The technical field to which the invention relates.

The present invention relates to a device and transfer method and to a device and method of reception. More specifically, the present invention relates to a device and transfer method and to a device and method that allow you to get all the information about configuring multi-segment broadcast.

The level of technology

Recently, terrestrial digital broadcasting has been deployed in a range of ultra-high frequency (UHF). Each physical channel of the terrestrial digital broadcast is divided into 13 segments, one segment of which is used for broadcasting for mobile terminals. Then the remaining 12 segments are used together for broadcasting for fixed terminals, such as television receivers (for example, see Patent document 1).

Currently, when the broadcast mobile terminal, transmit the same contents as when broadcasting for fixed terminals. Mobile terminals, mainly mobile phones made with the possibility of receiving broadcasting for mobile terminals, has already received wide distribution.

In addition, the wave of digital terrestrial Chironomidae Inoi transmission channels 13-52 UHF include many unused channels, in addition to the channels in which terrestrial digital broadcast actually performs in different regions. Therefore, consider how to effectively use these unused channels.

One possible way of effective use of unused channels is to perform a multi-segment broadcast in unused channels. It should be noted that the multi-segment broadcasting refers to the set of Monomeric broadcasts simultaneously transmitted on one physical channel. In other words, the multi-segment broadcasting refers to the broadcast, in which a frequency band of terrestrial digital broadcast is divided into many segments, and one or more services broadcast transmission is performed in the same segment.

By the way, the conventional mobile terminal for receiving broadcast to the mobile terminal receives the setting information, which is configuration information, such as frequency, and generates a table of information about the configuration below is called the setup table as follows:

Figure 1 shows a block diagram of a sequence of operations forming the configuration table using the normal mob is a high terminal.

At step S11, the mobile terminal sets the given physical channel (for example, a physical channel with the lowest frequency), as the target physical channel that should be processed. At step S12, the mobile terminal configures the Central segment of the target physical channel. At step S13, the mobile terminal determines whether the adopted transport stream (TS) of the Central segment of the target physical channel or not. If you determine that it was adopted, the process goes to step S14.

At step S14, the mobile terminal receives, from a received TS, table network information (NIT), which represents the information received from the network segment to the mobile terminal, described as the actual data NIT, and table service description (SDT), which is information about the service broadcast provided on the network segment for the mobile terminal, described as the actual data SDT. It should be noted that NIT refers to a table that contains information about the frequency for each service broadcasting and information about the corresponding service broadcast to adjust the carrier frequency of a particular service broadcasting. In addition, SDT refers to a table that contains meta-information for each service re-broadcast the ACI (for example, the name of the service and so on). After processing at step S14, the process goes to step S15.

On the other hand, if step S13 determines that the TS of the Central segment has not yet been adopted, the process skips step S14 and goes to step S15.

At step S15, the mobile terminal determines whether all of the physical channels is set as the target physical channel or not. If at step S15 determines that not all the physical channels have been set as the target physical channel, at step S16, the mobile terminal establishes the following physical channel (for example, a physical channel with the second lowest frequency)as the target physical channel, then the process returns to step S12. Then, the mobile terminal repeats the processing of steps S12-S16 until such time as all of the physical channels will not be set as the target physical channel.

On the other hand, if at step S15 determines that all of the physical channels have been set as the target physical channel, at step S17, the mobile terminal generates a table of settings based on the NIT and SDT, obtained in step S14.

In particular, as shown in figure 2, NIT contains the network ID, which is an ID unique to the network, TSID, which is an ID unique to TS, frequency, service ID, unique for broadcast, etc. corresponding to the segment for your cell phone the terminal. In addition, SDT contains meta information about the service broadcast corresponding to the segment to the mobile terminal, which includes TSID, service ID, service name, etc. for services to broadcast.

Thus, as shown in figure 2, the mobile terminal receives the service ID and frequency, as setting information, from the NIT of the Central segment of each physical channel, receives the service name of the corresponding SDT NIT, then associating the name of the service frequency to generate a configuration table.

It should be noted that in the example shown in figure 2, because the two services broadcast pass with time division in the Central segment of the physical channel 1 (PhCH-1), two service ID contained in the NIT of the Central segment of the physical channel 1.

Detailed description of the invention

The first option exercise

The configuration example of the first variant assests is of system transmission/reception

Figure 4 shows an example configuration of the first variant implementation of the system of transmission/reception in which the invention is applied.

The system 30 of the transmission/reception figure 4 includes stations 31-1 through 31-3 terrestrial broadcast, Monomeric relay station 32 and the receiving terminal 33.

Stations 31-1 through 31-3 terrestrial broadcast perform digital terrestrial broadcasting, using a ground wave digital broadcast. It should be noted that the lower station 31-1 through 31-3 terrestrial broadcast together called station 31 terrestrial broadcast, when it is not necessary to distinguish them individually.

Monomeric relay station 32 receives the broadcast to mobile terminals digital terrestrial broadcast (below called the broadcast of one segment)transmitted from station 31 terrestrial broadcast. Then, Monomeric relay station 32 performs a retransmission of a broadcast transmission of a single segment mode multi-segment broadcast in the difficult area of reception, using the unused channel wave of the terrestrial digital broadcast. It should be noted that the area difficult is the Riem relates to the field of as underground shopping center in which it is difficult to receive terrestrial digital broadcasts transmitted from stations 31 terrestrial broadcast.

The receiving terminal 33 is a mobile terminal, configured to receive a broadcast transmission of a segment transmitted from station 31 terrestrial broadcast and broadcast one segment is re-transmitted when the multi-segment broadcast of Monomeric relay station 32. Below broadcast one segment transmitted from Monomeric relay station 32, is called a re-broadcast of one segment.

As described above, since Monomeric relay station 32 performs retransmission broadcast one segment in the field of difficult reception, the receiving terminal 33 can reliably accept broadcast one segment, even in the difficult reception. Following broadcast of one segment will be described as an example of multi-segment broadcasting.

Description of the ground wave digital broadcast

Figure 5 presents the allocation of the band for the ground wave digital broadcast in which the system 30 of the transmission/reception figure 4.

As shown in figure 5, the system 30 of the transmission/reception 30, in the physical channel used for digital terrestrial broadcast among all of the bands of the ground wave digital broadcast, the broadcast of one segment perform in the band one segment in the centre, and broadcasting for fixed terminals perform in the band the other 12 segments.

On the other hand, in the unused channel re-broadcast of one segment performed with multi-segment broadcast. It should be noted that up to 13 logical channels when the re-broadcast of one segment may be transmitted for broadcast transmission in one of the unused channel.

Figure 6 presents an example configuration of a multi-segment broadcast, transmitted in one unused channel.

Multi-segment broadcast on 6 consists of a single segment broadcasts transmitted in the Central segments of the four physical channels.

The method of obtaining information about configuring

Figure 7 illustrates the method for obtaining configuration information when re-broadcast of one segment in the system 30 of transmission/reception.

As shown in Fig.7, for the doctrine of the setup information for the re-broadcast of one segment, usually can be used three ways. The first method consists in obtaining information about configuring by scanning wave broadcast. For the first method, the receiving terminal may receive information about configuring accept re-broadcast one segment in the scan result of the wave of the terrestrial digital broadcast. Thus, the user having the receiving terminal may automatically receive information about configuring accept re-broadcast one segment, without regard to whether the reception of the re-broadcast of one segment in the current location of the user or not.

The second method is that information about configuring embedded in the receiving terminal. In this second method, the receiving terminal must save the setup information. However, it is difficult to maintain all the information about configuring re-broadcasts of one segment, the changing regional. Thus, the second method does not match the re-broadcast of one segment.

The third way is to obtain information about configuring using anything other than wave broadcast (for example, by passing the data through the Internet ITP). In this third method, the user having the receiving terminal must know, is it possible to receive a re-broadcast of one segment in the current location of the user or not, and to identify the need for information on setting up about this re-broadcast of one segment, if it is present. However, it is difficult to know all the re-broadcast of one segment, the changing regional, as you change regions. Therefore, the third method does not match the re-broadcast of one segment.

Based on the above, in the system 30 of the transmission/reception is the first way for more information about setting up a re-broadcast of one segment. In particular, station 31 terrestrial broadcast and Monomeric relay station 32 transmits setting information of the wave of the terrestrial digital broadcast, and the receiving terminal 33 receives the setting information by scanning and contains it. Then, based on the supported configuration information, the receiving terminal 33 is configured on and plays the specified logical channel re-broadcast of one segment.

A detailed configuration example of the relay station one segm the NTA

On Fig shows a block diagram representing a detailed configuration example of the station 32 relay one segment.

Monomeric relay station 32 on Fig includes a receiving antenna 41, the tuners with 42-1 through 42-3 one segment, the converters 43-1 through 43-3 signal, multi-transmitter 44 and the transmitting antenna 45.

Tuner 42-1 one segment is configured to set the Central segment terrestrial digital broadcasts transmitted from stations 31 terrestrial broadcast and received via receiving antenna 41 and provides TS Monomeric broadcast, transmitted in the Central segment, the Converter 43-1 signals. TS Monomeric broadcast contains video data or audio data, NIT, SDT, etc. Monomeric broadcast.

As in Monomeric tuner 42-1, Monomeric tuners 42-2 and 42-3 are configured on the specified Central segment terrestrial digital broadcast and provide TS Monomeric broadcast that is configured on the Central segment, converters 43-2 and 43-3 signal.

When TS Monomeric broadcast provided from Monomeric tuner 42-1 is a TS that is intended for transmission in the Central segment of the INR is segmental broadcast, Converter 43-1 signal changes NIT contained in TS Monomeric broadcast, to generate the NIT of the Central segment of multi-segment broadcasting. Converter 43-1 signals TS provides Monomeric broadcast, updated generated NIT, multi-segment transmitter 44 as TS Monomeric re-broadcast, which must be uploaded to the Central segment.

On the other hand, when TS single segment broadcast tuner 42-1 one segment TS is not intended for transmission in the Central segment of multi-segment broadcasting, the transmitter 43-1 signals supports TS single segment broadcast tuner 42-1 one segment in the form as it is. Then the Converter 43-1 signals provides TS in multi-transmitter 44 as TS Monomeric repeat broadcast, intended for transfer to another segment, except for the Central segment of multi-segment broadcasting (below called the non-Central segment).

As in the Converter 43-1 signal converters 43-2 and 43-3 signals change NIT contained in TS Monomeric broadcast from Monomeric tuner 42-1, for the generators is of the NIT of the Central segment of multi-segment broadcasting. Then the converters 43-2 and 43-3 signals provide TS Monomeric broadcast, updated generated NIT, multi-segment transmitter 44 as TS Monomeric repeat broadcast, intended for transmission in the Central segment. In addition, as in the Converter 43-1 signal converters 43-2 and 43-3 signals provide TS Monomeric broadcast from Monomeric tuner 42-1, as he is, in the multi-transmitter 44 as TS Monomeric repeat broadcast, intended for transmission in non-Central segment.

It should be noted that below Monomeric tuners 42-1 - 42-3 together called Monomeric tuner 42, when there is no need to distinguish them individually. Similarly, converters 43-1 through 43-3 signals are called Converter 43 signals. In addition, three Monomeric tuner 42 and three Converter 43 of the signals presented on Fig, but are not limited to three.

Multi-segment transmitter 44 transmits the TS Monomeric repeat broadcast provided from the inverter 43 signals intended for transmission in the Central segment, through the transmitting antenna 45 in the Central segment. In addition, multi-transmitter 44 parade the TS Monomeric re-broadcast, provided from inverter 43 signals intended for transmission in non-Central segment, through the transmitting antenna 45 in the non-Central segment.

As described above, since Monomeric relay station 32 transmits NIT single segment broadcast, such as it is, as NIT non-Central segment, the signal Converter 43 should be performed only with the possibility of changing NIT Central segment. Thus, the cost of Monomeric relay station 32 can be reduced compared with the case where NIT all segments of multi-segment broadcasting should be changed.

Description NIT

Figure 9 illustrates the NIT transmitted in segments of the physical channel for Monomeric repeat broadcast.

As shown in Fig.9, in the Central segment s7 multi-segment broadcast NIT single segment broadcast, accept Monomeric relay station 32 with the handle multi-segment information (described below) and the like, attached thereto, is passed as NIT Monomeric repeat broadcast. On the other hand, in the non-Central segments s1, s2,..., s12, s13, NIT single segment broadcasts adopted the Monomeric retranslate the authorized station 32, in the form as they are passed as NIT Monomeric repeat broadcasts.

NIT single segment broadcasting, adopted Monomeric relay station 32 includes the network ID, information about TS Monomeric broadcast (below called information TS), etc. Information TS includes TSID TS, frequency, service ID, etc. Monomeric broadcast.

As noted above, the NIT of the Central segment of Monomeric repeat broadcast in multi-segment broadcast is a NIT single segment broadcast with multi-segment descriptor information, etc. attached to it. Thus, the multi-segment descriptor information may represent information indicating that the Central segment, the transmitting multi-segment descriptor information is a segment of multi-segment broadcasting.

Figure 10 shows the data structure of the NIT.

As shown in figure 10, NIT, 8-bit ID of the table (table_id), 1-bit indicator syntax plot (section_syntax_indicator) and 1-bit area for future use (reserved_future_use) placed starting from the top, in that order. For example, 0×40 is set as the ID of the table.

In addition, after the area for future use is litvania, is a 2-bit reserved area (reserved), 12-bit length of the plot (section_length), 16-bit network ID (network_ID), 2-bit reserved area (reserved) and a 5-bit version number (version_number) in that order. Then, a 1-bit indicator of the next current (current_next_indicator), 8-bit sector number (section_number), an 8-bit number of the last plot (last_section_number) and 4-bit area for future use are located in the specified order.

Next, a 12-bit length descriptor network (network_descriptor_length) and 4-bit network loop are located in the specified order. In network loop handles, comprising a handle name, (network_name_descriptor), the descriptor system (system_management_descriptor), etc. are set for each network ID submitted in the previous step. Descriptor name of the network represented by the network name. Descriptor administration system presents information about whether the network is a broadcast transmission or a data transmission network.

After the network loop 12-bit area for future use, the length of the loop TS (transport_stream_loop_length), loop TS and 32-bit CRC (check for cyclic redundancy) 32 (CRC_32) are in order. In the loop TS descriptor list services (service_list_descriptor), the descriptor system ground shipping (terrestrial_delivery_system_descriptor), etc. provided for every what about the TS. In the descriptor list of services service ID that is the identification information services broadcast, and the service type that indicates the type of services broadcast (e.g., television broadcast, radio broadcast etc). Descriptor system ground shipping presents information about the configuration.

It should be noted that in the NIT of the Central segment of Monomeric repeat broadcast information on the broadcast for fixed terminals, at least 7 bytes (below called the information about the broadcast to fixed terminal), represented in the descriptor in the loop TS NIT original Monomeric broadcast, removed. Then, within the size range of information for information about the broadcast to mobile terminals located handle multi-segment information (multi_segment_info_descriptor), which presents a multi-segment descriptor information.

Thus, the multi-segment descriptor information presented in the size range of information for information about the broadcast for fixed terminals. In line with this, the number of TS packets Monomeric re-broadcast is peredachi equal to the number of TS packets of the original Monomeric broadcast. In other words, the NIT won't change increases the number of packets. Consequently, changes in NIT does not require changes to other information in TS that can prevent the complication of functions Monomeric relay station 32.

Description handle multi-segment information

Figure 11 shows an example of the description of the multi-segment descriptor information.

As shown in figure 11, the multi-segment descriptor information that is described in the multi-segment descriptor information includes an 8-bit tag descriptor (descriptor_tag), 8-bit length descriptor (descriptor_length), 4-bit multi mode (multi_segment_mode), 4-bit reserved field (reserved) and multi-bit data size of 16×N-bit (multi_segment_bitmap).

Multi-segment mode is a mode that represents the interval between the frequencies of the segments of multi-segment broadcasting (below called the interval of the segment).

On Fig shows an example of the multi-segment mode.

In multi-segment mode on Fig, mode 1 is the interval of segment Δf1, as shown at position A on Fig. In this case, the total number of segments multi-segment broadcast is 13. Then, for example, one-tenth the frequency of the multi-segment broadcasting F10 specify how F10=fcenter+3Δf1 where fcenter is particularly the frequency of the Central segment, or seventh segment F7.

In addition, in multi-segment mode on Fig, mode 2 is the interval segment Δf2, as shown in position on Fig. In this case, the total number of segments multi-segment broadcast is 11. Then, for example, the second multi-frequency broadcast set F2 as F2=fcenter-4Δf2 where fcenter represents the frequency of the Central segment and the sixth segment F6.

On Fig shows an example of the configuration of the multi-bit data.

Multi-bit data on pig include bit data, each of which contain 16 bits, representing the multi-segment information link (Multi_segment_layout), the connection information (Segment_Connection_Group) and information Monomeric indication retransmission (1Seg_Redistribution_Indication). View information using bit data, therefore, provides the opportunity to minimize the amount of information.

Information about multi-segment layout (the layout) is the layout of the segment, used for multi-segment broadcast (below called a segment broadcast), that is, the segment operations in the physical channel for which emit multi-segment broadcast.

In particular, each of the top is 13 bits of the 16-bit bit data, representing multi-segment layout information correspond to each segment of the physical channel for which emit multi-segment broadcast. Then, for example, a single bit equal to "1", indicates that the segment corresponding to this bit represents the segment of the broadcast, and a bit equal to "0"indicates that the segment corresponding to this bit is not a segment of the broadcast.

The lower 3 bits are used to represent the information that the bit data, which includes the lower 3 bits to represent the multi-segment information of the layout. In the example shown in Fig, "000" indicates that the bit data are multi-segment information of the layout.

Given that the above multi-segment information the layout is the layout of the segment of the broadcast, when the receiving terminal 33 can be identified by the multi-segment information about the layout, which is the segment of the broadcast physical channel of the multi-segment broadcasting. In addition, the receiving terminal 33 recognizes in advance the frequency of the Central segment of multi-segment broadcasting, fcenter. Thus, the receiving terminal 33 is able to count the frequency of NEGP is enta broadcast, as shown in Fig.

The connection information is the layout of the segment of broadcast, used to transfer Monomeric repeat broadcast of the same Monomeric relay station 32. The connection information is described for each Monomeric relay station 32.

In particular, each of the upper 13 bits of the 16-bit bit data representing the connection information corresponds to each segment of the physical channel to which the selected multi-segment broadcasting. Then, for example, a single bit equal to "1", indicates that the segment of the broadcast corresponding to this bit transfers the same Monomeric relay station 32, which transmits the segment broadcast corresponding to another bit equal to "1". On the other hand, the bit "0"indicates that the segment of the broadcast corresponding to this bit is passed through the other Monomeric relay station 32, in addition to Monomeric relay station 32, which transmits the segment broadcast corresponding to this bit is equal to "1".

The low 3 bits are used to represent the information that the bit data, which includes the low 3 bits, is inform the data connection. In the example shown in Fig, "001" indicates that the bit data represents the connection information.

The connection information presented thus reduces the time required for the settings in the receiving terminal 33. In particular, TS, passed the same Monomeric relay station 32 is OFDM multiplexing (orthogonal frequency division) synchronized. Thus, the receiving terminal 33 can eliminate OFDM synchronization during configuration to reduce the time required to configure, by continuously tuning segments broadcast, used for transmission of the same Monomeric relay station 32.

In the system 30 of the transmission/reception according to figure 4, as shown in Fig, one Monomeric relay station 32 transmits the TS Monomeric repeat broadcasts for all segments of the broadcast, the time required for setting is short, regardless of the order of the settings on the segments of the broadcast.

However, another scheme transfer Monomeric repeat broadcast system 30 of the transmission/reception can be a distributed scheme in which TS Monomeric re-broadcast transmit using on the natives Monomeric relay station for each segment broadcast, as shown in Fig. In the example shown in Fig, each of the three Monomeric relay stations 51-1 - 51-3 transmits TS Monomeric repeat broadcast for one segment broadcasting.

In addition, another scheme transfer Monomeric repeat broadcast system 30 of the transmission/reception can be a transmission scheme that is a hybrid for the centralized scheme, in which Monomeric relay station 32 transmits the TS Monomeric repeat broadcasts for all segments of the broadcast, and distributed scheme, as shown in Fig, below called a hybrid scheme. In the example shown in Fig, one Monomeric relay station 61-1 transmits TS Monomeric repeat broadcasts for the three segments of the broadcast, and each of the two Monomeric relay stations, 61-2 and 61-3 transmits TS Monomeric repeat broadcast for one segment broadcasting.

Thus, when the transmission scheme is a distributed or hybrid scheme, the time taken for setting differs depending on the order settings on the segments of the broadcast. In particular, when the segment is broadcast, used for transmission of the same Monomeric stations broadcast continuously tune the synchronization of the OFDM eliminated to reduce the time occupied by the setting. However, when constantly to tune into segments broadcast used for other Monomeric relay stations, perform synchronization of OFDM to increase the time required for setting.

Thus, in the system 30 of transmission/reception, single segment repeater station 32 transmits the connection information, and the receiving terminal 33 controls the order settings based on the connection information to reduce the time required for tuning. For example, as shown in Fig, when the connection information indicates that six to eight segments represent segments of the broadcast of the same Monomeric relay station, the receiving terminal 33 is configured on the eighth segment, after setting the sixth segment. This allows you to tune into the eighth segment in a shorter time than in the case of the settings on the eighth segment, after tuning to the segment of the broadcast of another Monomeric relay station (for example, the fourth segment).

Returning to Fig, information indicating odesign nteu re-transmission (re-transfer) shows the layout of the segment, used for Monomeric repeat broadcast among segments of the broadcast.

In particular, each of the older 13 bits of the 16-bit bit data representing information Monomeric indication retransmission corresponds to each segment of the physical channel, which produce multi-segment broadcast. Then, for example, a single bit equal to "1", indicates that the segment of the broadcast corresponding to that bit is a segment broadcast Monomeric repeat broadcast. On the other hand, one bit of "0"indicates that the segment of broadcast corresponding to this bit represents the segment of the broadcast for broadcast, which is not Monomeric repeat the broadcast.

It should be noted that, because the system 30 send/receive all broadcast, transferred on the multi-segment broadcast, represent Monomeric repeat broadcast, senior 13 bits bit data information Monomeric indication of retransmission is equal to senior 13 bits of bit data of the multi-segment layout.

The low 3 bits in the information Monomeric indication retransmission are used to represent the information that bit data represents information Monomeric indication of retransmission. In the example shown in Fig, "010" indicates that the bit data represents information Monomeric indication retransmission.

It should be noted that, when the information about the information about the broadcast for fixed terminals, which must be removed is small, multi-bit data may not be included in the bitmap data connection information and the information of the multi-segment layout.

On the other hand, when the amount of information for broadcast to mobile terminals, which must be removed is large, and another handle, but handle multi-segment information can be optionally placed on the amount of information for broadcast to mobile terminals, may be placed in the descriptor information Monomeric resubmit.

Description of the descriptor information Monomeric retransmission

On Fig shows an example of a detailed configuration descriptor information Monomeric resubmit.

As shown in Fig, the descriptor information Monomeric retransmission (one_Seg_redistribution_info_descriptor) includes an 8-bit tag descriptor (descriptor_tag), 8-bit is th length of the descriptor (descriptor_length), 8-bit number TS (no_of_ts) and 16×N-bit network ID terrestrial digital broadcast (terrestrial_network_id).

Number TS is a TSID multi-segment broadcast physical channel, which includes the Central segment, which posted the descriptor information Monomeric retransmission. In addition, for the network ID information that identifies the source Monomeric broadcast Monomeric re-broadcast segment broadcast, presented in ascending order of frequency segments of the broadcast.

Process description Monomeric relay station

On Fig shows a block diagram of a sequence of operations that describe the transfer process Monomeric relay station 32.

At step S31, Monomeric tuner 42 is configured to set the Central segment terrestrial digital broadcasts transmitted from stations 31 terrestrial broadcast and received via receiving antenna 41 and provides TS Monomeric broadcast in the Central segment of the inverter 43 signals.

At step S32, the inverter 43 signals determines whether the TS supplied from Monomeric tuner 42, TS, which should be transferred to the Central segment or not. If at step S32 determines that TS must be uploaded to the Central segment, at step S33, the inverter 43 signal changes NIT TS provided from Monomeric tuner 42.

In particular, the inverter 43 signals removes the information about the broadcast for the fixed terminals of the NIT and places the handle multi-segment or multi-segment descriptor information and descriptor information Monomeric re-transmission number information for the broadcast to mobile terminals. Then the Converter 43 signal is TS containing the modified NIT, multi-segment transmitter 44, and then the processing goes to step S34.

On the other hand, if at step S32 determines that TS should not pass in the Central segment, the inverter 43 signal is TS, as it is in multi-transmitter 44, and then the processing goes to step S34.

At step S34, multi-transmitter 44 transmits the TS supplied from the Converter 43 of signals in a given segment through the transmitting antenna 45. In particular, multi-transmitter 44 transmits the TS with NIT, modified at step S33, in the Central segment, and transmits the TS with unmodified NIT in non-Central segment. Then processing ends.

An example of the detailed configuration of the receiving terminal

On Fig shows a block diagram representing an example of the detailed configuration of a receiving terminal 33 in figure 4.

On Fig the receiving terminal 33 includes an antenna 71, the tuner 72, the demultiplexer 73, the video decoder 74, the selector 75, the display 76, the audio decoder audio 77, loudspeaker 78, browser 79 and the controller 80.

The tuner 72 performs the setting based on the configuration information provided from the controller 80, and takes Monomeric repeat broadcast of the specified logical channel from the relay Monomeric station 32 via the antenna 71. The tuner 72 provides the adopted TS to the demultiplexer 73.

The demultiplexer 73 further demultiplexes the TS supplied from the tuner 72, a variety of information, including video data, audio data, control information display for the browser that displays the Monomeric broadcast and PSI (Information specific to the program). It should be noted that PSI is a generic term table including information for receiving the broadcast services transmission, such as NIT, RMT (table card program), PAT (table Association program), etc.; frequency information; and information that identifies the service, the appropriate service broadcasting, and is a management information system. Demultiple the SOR 73 provides video data to the video decoder 74 and provides the audio data in the audio decoder audio 77. In addition, the demultiplexer 73 provides the management information is displayed to the browser 79 and provides a variety of information in the PSI in the controller 80.

The video decoder 74 decodes the video data supplied from the demultiplexer 73, using a decoding scheme corresponding to the encoding scheme used in station 31 terrestrial broadcast, and presents the decoded video data to the selector 75, in accordance with control by the controller 80.

The selector 75 selects the video data supplied from the video decoder 74, or video data provided from the browser 79, and provides the selected video data to the display 76, in accordance with control by the controller 80. The display 76 displays the image Monomeric broadcast or Monomeric repeat broadcast based on the video data supplied from the selector 75.

Audio decoder audio 77 decodes the audio data supplied from the demultiplexer 73, using a decoding scheme corresponding to the encoding scheme used in station 31 terrestrial broadcast and provides the decoded audio data to the speaker 78, in accordance with control by the controller 80. Loudspeaker 78 outputs a sound corresponding to the audio data from the audio decoder 77, as the sound onesegment the th broadcast Monomeric or re-broadcast.

The browser 79 interprets information display control provided from the demultiplexer 73, to generate video data, and provides the video data selector 75.

The controller 80 provides, in turn, information about the configuration of the Central segments of the physical channels of the digital terrestrial wave broadcast in the tuner 72. In addition, the controller 80 calculates the frequencies of other segments of the broadcast, in addition to the Central segment on the basis of NIT Central segment when Monomeric re-broadcast and the frequency fcenter. Then, the controller 80 provides the calculated values of frequency, as setting information, the tuner 72, in order, based on connection information.

In addition, the controller 80 generates the table based configuration NIT and SDT Monomeric broadcast provided from the demultiplexer 73, or NIT Central segment of the Monomeric repeat broadcasts, SDT segments broadcasts for Monomeric re-broadcasts the frequency fcenter and calculated frequencies. Then, the controller 80 stores the generated table settings in the internal memory (not shown).

In addition, in response to the indication from the user, the controller 80 provides n is the rank of the services, registered in the table settings in the browser 79, to ensure the representation of names of services on the display 76. The user sees the names of the services presented on the display 76 to indicate the choice of the name services for services broadcast for viewing. Based on this indication of the selection, the controller 80 reads the configuration information from the configuration table corresponding to the service name, for viewing, and provides information about configuring the tuner 72.

In addition, the controller 80 controls the video decoder 74, the selector 75, the audio decoder 77 and browser 79 on the basis of various information in the PSI supplied from the demultiplexer 73. In particular, the controller 80, for example, controls the video decoder 74 and the audio decoder 77 so that the video output from the video decoder 74, and the audio data output from the audio decoder 77, are synchronized.

The method of formation table settings

On Fig illustrates the method for forming the table settings in the receiving terminal 33.

As shown in Fig, the receiving terminal 33 scans the Central segments of the physical channels of the digital terrestrial wave broadcast in order from low to high frequencies. In particular, the tuner 72 receiving terminal 33 configures the Central segment of each physical channel in the order of the low to high frequencies and receives the TS of the Central segment.

Then, at the beginning of the TS of the Central segment 91 of the physical channel for which emit terrestrial digital broadcasting, get NIT and SDT Monomeric broadcast, which must be uploaded to the Central segment 91. Since the Central segment 91 is a segment terrestrial digital broadcast, NIT Central segment 91 does not contain the multi-segment descriptor information. In line with this, goal setting moves to the Central segment of the next physical channel.

Further, in the example Fig, TS in the Central segment of the next physical channel is absent, so that the goal setting moves on to the Central segment 92-1 next physical channel. Consequently, NIT and SDT broadcast in the Central segment 92-1 obtained from the TS of the Central segment 92-1.

In the example on Fig because the Central segment 92-1 represents the Central segment of the physical channel in which the selected Monomeric repeat broadcast, NIT Central segment 92-1 contains a multi-segment descriptor information. In line with this, information about multi-segment layout and information of this mode multi-segment descriptor information and the frequency fcenter use to calculate cascadepoint 92-2 to 92-5 broadcast, in addition to the Central segment 92-1.

Then, based on the calculated frequencies and connection information, other segments 92-2 to 92-5 broadcast, except for the Central segment 92-1, are to configure, in turn, so that the segments of the broadcast for the same Monomeric relay station 32 were located continuously. This provides broadcast SDT Monomeric repeat broadcasts in other segments 92-2 to 92-5 broadcast, except for the Central segment 92-1.

Next goal setting moves to the Central segment 93 of the next physical channel. Setup continues similarly until such time as the setting will not be performed for all physical channels of the digital terrestrial wave broadcast.

Then create a table-based configuration NIT and SDT Monomeric broadcast, or NIT Central segment of the Monomeric repeat broadcasts, SDT segments broadcast Monomeric repeat broadcasts, frequency fcenter and calculated frequencies.

It should be noted that in the example shown in Fig, other segments from 92-2 to 92-5 broadcast, except for the Central segment 92-1, also configured. However, when the NIT of the center of Lenogo segment 92-1 contains descriptor information Monomeric retransmission, segments from 92-2 to 92-5 broadcast can be configured. In this case, on the basis of TSID contained in the descriptor information Monomeric retransmission, SDT original Monomeric broadcast already adopted Monomeric repeat broadcast is received and used in the formation of the configuration table.

On the other hand, when NIT Central segment 92-1 not contains the bitmap data information multi-link, the receiving terminal 33 is unable to recognize the segments from 92-2 to 92-5 broadcast, then tune to the Central segment 92-1 and all non-Central segments. This allows the receiving terminal 33 can recognize information about configuring other segments of the broadcast, in addition to the Central segment.

On Fig illustrates a conventional receiving terminal 95, which can't take Monomeric repeat broadcast transmission, and the receiving terminal 33, which receives a ground wave digital broadcast transmission system 30 of transmission/reception.

Conventional receiving terminal 95, typically scans the Central segments of the physical channels in order from low to high frequencies, to generate a configuration table, as in the receiving terminal 33. However, since the receiving terminal 95 cannot accept the mother Monomeric re-broadcast, the receiving terminal 95 ignores the multi-segment descriptor of the NIT information contained in the TS of the Central segment of the physical channel for which distinguish Monomeric repeat broadcast. Thus, the receiving terminal 95 is not faulty, but cannot tune to another segment of the broadcast, in addition to the Central segment.

Consequently, when the receiving terminal 95 receives a ground wave digital broadcast transmission system 30 of the transmission/reception table settings form of the NIT and SDT for Monomeric broadcast and Monomeric repeat broadcast of the Central segments of the terrestrial digital broadcast.

On the other hand, the receiving terminal 33 can take Monomeric re-broadcast, then can recognize multi-segment descriptor of the NIT information contained in the TS of the Central segment of the physical channel to which the selected Monomeric re-broadcast, and can be configured to a different segment of the broadcast, in addition to the Central segment. Therefore, in the receiving terminal 33, table settings form of the NIT and SDT all Monomeric broadcasts and Monomeric repeat Chironomidae the data transmission wave of the terrestrial digital broadcast.

As noted above, when a conventional receiving terminal 95 receives a ground wave digital broadcast transmission system 30 of the transmission/reception, since the receiving terminal 95 can't take Monomeric re-broadcast, the receiving terminal 95 is unable to register information about configuring Monomeric re-broadcast non-Central segment table settings. However, even an ordinary reception terminal 95, you may receive information about configuring single segment broadcast, transmitted from station 31 terrestrial broadcast. Thus, the wave of digital terrestrial broadcasting in accordance with the invention does not affect the reception of Monomeric broadcast conventional receiving terminal 95.

Example of a table configuration settings

On Fig shows an example of a configuration table, formed the receiving terminal 33.

In the example shown in Fig, from the third to the tenth segments of the physical channel, for which there Monomeric repeat broadcast, installed in segments of the broadcast, and the information of the mode set in the mode 2. It should be noted that, as shown in Fig, mode 2 indicates that the interval of segment represents a Δf2, and one Phi is practical channel in mode 2 consists of 11 segments.

In this case, first, recognize the sixth segment, which represents the Central segment that is configured to handle multi-segment information. Then the frequency of other segments of the broadcast, in addition to the Central segment, calculated on the basis of information regime and information multi-segment layout for the multi-segment descriptor information and the frequency fcenter.

In particular, the frequency Fk are estimated using the expression Fk=fcenter±Δfm×N, where Fk is the frequency of k-th segment, which represents the segment of the broadcast, Δfm is the interval segment in mode m, and N represents the number of segments from the Central segment to the k-th segment.

It should be noted that the frequency fcenter of the Central segment used in this calculation is not the rate specified in NIT Central segment, but represents the frequency actually used when configuring the Central segment using the receiving terminal 33. The reason why the frequency specified in NIT Central segment is not used as a frequency fcenter, is that the frequency specified in NIT Central segment still represents the frequency of the original Monomeric broadcast for Monomeric re-broadcast lane the cottage.

When the frequencies of the segments broadcast rely therefore on the basis of frequency segments of the broadcast, other segments of the broadcast, in addition to the Central segment, set in order, based on the connection information, and receive SDT segments of the broadcast. It provides registration of names of services contained in the SDT segments of the broadcast, and frequency fcenter or calculated frequencies in the tuning table.

In addition, the table settings, the number of connection groups each segment broadcast register on the basis of connection information of the multi-segment descriptor information. The number of connection groups corresponds to the source of each segment broadcast. The same number of defined segments of the broadcast, with the same source. In the example shown in Fig, TS all segments of the broadcast transmit from the same Monomeric relay station 32, then the same number of "G1" connection group register for all segments of the broadcast.

Description of the processing of the receiving terminal

On Fig shows the block diagram of the sequence of operations forming the configuration table using the receiving terminal. Such formation of table settings begin, for example, when the user designates a receiving configuration table.

At step S51, the controller 80 sets the given physical channel (for example, a physical channel with the lowest frequency), as the target physical channel for processing. Then, the controller 80 provides the frequency of the Central segment of the target physical channel for the tuner 72, as setting information.

At step S52, the tuner 72 configures the Central segment of the target physical channel based on the configuration information from the controller 80.

At step S53, the tuner 72 determines whether accepted or not TS of the Central segment of the target physical channel. If you determine that it was adopted, the processing goes to step S54.

At step S54, the demultiplexer 73 further demultiplexes the TS of the Central segment of the target physical channel received by the tuner 72, for receiving the NIT and SDT. Then, the demultiplexer 73 provides NIT and SDT in the controller 80.

At step S55, the controller 80 determines whether the accepted TS of the Central segment of multi-segment broadcasting or not, or does NIT provided to demultiplexer 73, multi-segment descriptor information or not.

If at step S55 determines that the adopted TS is a TS of the Central segment of multi-segment Shirokova the positive transfer, the processing goes to step S56. At step S56, the controller 80 calculates the frequencies of other segments of the broadcast, in addition to the Central segment, based on the information mode and information multi-link multi-segment descriptor information contained in NIT Central segment, and frequency fcenter. Then, the controller 80 provides the calculated frequency, as setting information, the tuner 72, in order based on the connection information.

At step S57, the tuner 72 configures other segments of the broadcast, except for the Central segment of the target physical channel based on the configuration information from the controller 80. At step S58, the demultiplexer 73 further demultiplexes the TS of other segments of the broadcast, except for the Central segment of the target physical channel received by the tuner 72, for receiving the SDT. Then the demultiplexer 73 provides SDT in the controller 80, and the processing goes to step S59.

On the other hand, if at step S53 determines that the TS of the Central segment of the target physical channel has not been adopted, or, if at the step S55 determines that TS, adopted at step S55, it is not the TS of the Central segment of multi-segment broadcast, the processing goes to step S59.

At step S59, the controller 80 determines whether all of the physical channels is set to the target physical channel, or not. If at step S59 determines that not all the physical channels have been set as the target physical channel, at step S60, the controller 80 sets the following physical channel (for example, a physical channel with the second lowest frequency)as the target physical channel, then the process returns to step S52. Then, the process at steps S52 - S60 to repeat until all the physical channels will not be set as the target physical channel.

On the other hand, if at step S59 determines that all of the physical channels is set as the target physical channel, the processing goes to step S61.

At step S61, the controller 80 generates a table of settings based on the NIT and SDT Monomeric broadcast, or NIT Monomeric repeat broadcasts of the Central segment, SDT Monomeric repeat broadcasts segments of the broadcast, the frequency fcenter and the frequency calculated in step S56. Then, the controller 80 stores the created table settings in the internal storage device, after which the processing ends.

As noted above, the Monomeric relay station 32 generates NIT Central segment of the Monomeric repeat broadcast, including NIT single segment broadcast, and the handle of multi-stakeholder who gmental information then passes NIT in the Central segment of the Monomeric repeat broadcast. Then, the receiving terminal 33 receives the TS of the Central segment of each physical channel, and, in accordance with the multi-segment descriptor information contained in TS, recognizes whether the Central segment segment multi-segment broadcast or not, for configuration management. This allows you to recognize the setup information for all Monomeric repeat broadcasts.

It should be noted that in the above description, the names of the services on the basis of SDT must be registered in the setting table, but the names of the services may not be registered in the setting table. In this case, other segments of the broadcast, in addition to the Central segment, should not be configured.

In addition, the inverter 43 signals Monomeric relay station 32 may not only put the multi-segment descriptor information, etc. in the NIT transmitted to the Central segment, but also to change the frequency of the Monomeric broadcast specified in the NIT, the frequency of the Central segment. In this case, specified in NIT frequency of the Central segment of Monomeric repeat broadcast, can be used as a frequency fcenter.

The second option exercise

The configuration example of the second variant of implementation of the system transmission/reception

On Fig shows a configuration example of the second variant of implementation of the system of transmission/reception in which the invention is applied.

System 100 transmission/reception pig includes station 31 terrestrial broadcast, public station from 101-1 to 101-3 broadcast and the receiving terminal 102. It should be noted that those components that are shown in figure 4, are denoted by the same reference numbers of positions and will not be repeatedly described.

The system 100 to transmit/receive on Fig transmits multi-channel public broadcasting, which is not Monomeric re-broadcast, multi-segment broadcast, using an unused channel wave of the terrestrial digital broadcast.

It should be noted that multi-channel public broadcasting is a Monomeric broadcast, performed in different ways, using a number of logical channels in a limited area. The example multi-channel public broadcasting can be a broadcast related to an amusement Park, which is considered the only within the amusement Park. Below multichannel public broadcast is simply a public broadcast.

Station 101-1 public broadcast system 100 transmit/receive transfers of public broadcasting, accept only within the scope of A service, as a multi-segment broadcasting, using the unused channel wave of the terrestrial digital broadcast.

On the other hand, the station 101-2 public broadcasting transmits public broadcasting, accept only within the area of service, the quality of multi-segment broadcasting, using an unused channel wave of the terrestrial digital broadcast. In addition, the station 101-3 public broadcasting transmits public broadcasting, accept only within the region serving as the multi-segment broadcasting, using the unused channel wave of the terrestrial digital broadcast.

In the example shown in Fig, A maintenance area includes the area In and out of service. In particular, the station 101-1 public broadcasting is a Central station having given blast, as the area is A maintenance, and station 101-2 and 101-3 public broadcasting are local stations, which are building or Park within the area, as areas B and C service, respectively.

Accordingly, in this case, the public broadcasting Central station, with a large reception area (station 101-1 public broadcasting), obviously, more is more important than public broadcast local stations (stations 101-2 and 101-3 public broadcast).

Thus, in the system 100 transmission/reception, public broadcast stations 101-1 public broadcasting, as a Central station, allocate to the Central segment, allowing more reliable reception more important public broadcasts using the receiving terminal 102.

It should be noted that, when the importance of public broadcasts is not so obvious as for the system 100 to transmit/receive on Fig, dedicated lanes for public broadcasts within an unused channel does not need to be obviously defined.

The receiving terminal 102 is a mobile is erminal, made with the possibility of receiving Monomeric broadcasting and public broadcasting. Thus, when the user is working with the receiving terminal 102 is in the area of A service, as shown in Fig, the receiving terminal 102 can accept a single segment broadcasting and the public broadcasting station 101-1 - 101-3 public broadcasting.

It should be noted that below the station 101-1 - 101-3 public broadcast together called station 101 public broadcast, when there is no need to distinguish them individually. Now public broadcasting will be described as an example of the multi-segment broadcasting.

An example of a detailed configuration of the station of the public broadcasting

On Fig shows a block diagram representing an example of a detailed configuration of a workstation 101 public broadcasting.

Station 101 public broadcast on Fig includes generator 121 relevant information, block 122 receiving video data, the video encoder 123, block 124 receiving the audio data, the audio encoder 125, a multiplexer 126, a transmitter 127, and an antenna 128.

It should be noted that NIT public broadcast, transmitted in the Central segment that contains the handle of the multi-segment information.

Block 122 receiving receives video data video data public broadcast from the built-in HDD (hard drive disk), which is not shown, the external server and the like, and provides video data to the video encoder 123.

The video encoder 123 encodes the video data supplied from the block 122 receiving video data in accordance with a coding scheme such as MPEG2 (Group of experts in the field of moving image, phase 2), and provides the encoded video data to the multiplexer 126.

Block 124 receive audio receive audio data public, broadcast from the built-in HDD, not shown, of the external server and the like, and provides these audio data in the audio encoder 125.

Audio encoder 125 encodes the audio data supplied from the block 124 receiving the audio data, in accordance with a coding scheme such as MPEG2, and provides the encoded audio data to the multiplexer 126.

The multiplexer 126 to multiplexer the t relevant information from the generator 121 relevant information video data from the video encoder 123 and the audio data from AudioCodes 125, to generate the TS, and TS provides the transmitter 127.

The transmitter 127 transmits the TS supplied from the multiplexer 126 in the segment via the antenna 128.

Description of the work station of the public broadcasting

On Fig shows the block diagram of the sequence of operations describing the transmission station 101 public broadcasting.

At step S71, the generator 121 relevant information generates PSI for public broadcasting, information management, mapping, etc. as relevant information, and then provides the relevant information to the multiplexer 126.

At step S72, the block 122 receiving video get video public, broadcast from the built-in HDD, which is not shown, the external server and the like, and provides these video data to the video encoder 123.

On the stage set S74, the block 124 receive audio receive audio data public broadcast from the built-in HDD, which is not shown, the external server and the like, predstavlyaet these audio data in the audio encoder 125.

At step S75, audio encoder 125 encodes the audio data supplied from the block 124 receiving the audio data, in accordance with a coding scheme such as MPEG2, and provides these the coded audio data to the multiplexer 126.

On the stage set s76, the multiplexer 126 multiplexes the information from the generator 121 relevant information, video data from the video encoder 123 and the audio data from AudioCodes 125, to generate the TS.

In particular, the multiplexer 126 generates a TS containing the NIT, which includes a multi-segment descriptor information, as the TS of the Central segment. In addition, the multiplexer 126 generates a TS containing the NIT, which does not include the multi-segment descriptor information, like TS off-center segment. Then, the multiplexer 126 provides the generated TS to the transmitter 127.

At step S77, the transmitter 127 transmits the TS supplied from the multiplexer 126 in the segment via the antenna 128, then processing ends.

A detailed configuration example of the receiving terminal

On Fig shows a block diagram representing a detailed configuration example of the receiving terminal 102 on Fig.

On Fig the receiving terminal 102 includes an antenna 71, the tuner 72, the demultiplexer 73, the video decoder 74, the selector 75, the display 76, the audio decoder audio 77, loudspeaker 78, browser 79 and the controller 141. It should be noted, is arranged, what those components that are shown in Fig, are denoted by the same reference numbers of positions and will not be repeatedly described.

As with the controller 80 on Fig, the controller 141 provides, in turn, information about the configuration of the Central segments of the physical channels of the digital terrestrial wave broadcast in the tuner 72. In addition, the controller 141 calculates the frequencies of other segments of the broadcast, in addition to the Central segment, on the basis of NIT Central segment of the public broadcast. Then, the controller 141 provides the calculated frequency, as setting information, the tuner 72, in order, based on connection information.

In addition, the controller 141 generates a table based configuration NIT and SDT Monomeric broadcast provided from the demultiplexer 73, or NIT and SDT of the Central segment of the public broadcast, and calculated frequencies then saves the table settings in the internal memory (not shown).

In addition, as with the controller 80, in response to the indication from the user, the controller 141 provides the names of the services registered in the table is set up, the browser 79 to enable the representation of names of services on the display 76. The user sees the name of the service, to provide the Lenno on the display 76, to denote the choice of the name service broadcast for viewing. As with the controller 80, based on the indication of the selection, the controller 141 reads the configuration table the configuration information corresponding to the service name, for viewing, and provides information about configuring the tuner 72.

In addition, as with the controller 80, the controller 141 controls the video decoder 74, the selector 75, the audio decoder 77 and browser 79 on the basis of various information in the PSI supplied from the demultiplexer 73.

The method of formation table settings

On Fig illustrates the method for forming the table settings in the receiving terminal 102.

As shown in Fig, as with the receiving terminal 33, the receiving terminal 102 scans the Central segments of the physical channels of the digital terrestrial wave broadcast in order from low to high frequencies.

Then get the TS of the Central segment 91 and 93 of physical channels, for which emit terrestrial digital broadcast, then NIT and SDT Monomeric broadcasts, which were transferred to the Central segments 91 and 93, are obtained from TS. In addition, get the TS of the Central segment 92-1 physical channel for which allocate public broadcasting, then NIT and SDT public, broadcast, re the ACI, which is intended for transmission in the Central segment 92-1, obtained from TS.

After that, other frequency segments 92-2 to 92-5 broadcast, except for the Central segment 92-1, calculated on the basis of information multi-composition and information mode multi-segment descriptor information contained in NIT Central segment 92-1 and the frequency fcenter. Then the table setup form based on the NIT and SDT Monomeric broadcast, or NIT and SDT public broadcast of the Central segment, and on the calculated frequency.

Example of a table configuration settings

On Fig shows an example of a configuration table, formed the receiving terminal 102.

In the example shown in Fig, the first, fourth, sixth, eighth, tenth, and thirteenth segments of the physical channel, which allocate public broadcasting, set for segments of the broadcast, and information mode is set to 1. It should be noted that, as shown in Fig, mode 1 indicates that the interval of the segment is Δf1, and one physical channel in mode 1 consists of 13 segments.

In this case, at the beginning of the seventh segment, which represents the Central segment, encourage and recognize the multi-segment descriptor information. For the eat other frequency segments broadcast, in addition to the Central segment, calculated on the basis of the information mode and the multi-segment information the layout of the multi-segment descriptor information, and frequency fcenter contained in the NIT of the Central segment. Then, the table settings, service names related to the names of the services contained in the SDT of the Central segment is recorded in Association with the frequency fcenter and calculated frequencies.

In the example on Fig, service name, service in region 1-main", relating to the service name, service in region 1"contained in the SDT of the Central segment registered as the name of the Central services segment in Association with the frequency fcenter. In addition, service name, service in region 1-subl", etc. relating to the service name "service 1", registered as a service name other segments of the broadcast, in addition to the Central segment, in Association with the calculated frequencies.

In addition, the table settings, the number of connection groups each segment broadcast is also registered on the basis of connection information of the multi-segment descriptor information. In the example shown in Fig, TS of the seventh segment, which represents the Central segment, and the TS of the sixth and eighth segments, is passed from the same public station 101 broadcasts is peredachi, and the same number "G1" group of the compounds registered for the sixth - eighth segments.

Description of the processing of the receiving terminal

On Fig shows the block diagram of the sequence of operations forming configuration table the receiving terminal 102. This formation configuration table begins, for example, when the user indicates that you want to get the table settings.

The processing at steps S91-S98 is similar to the processing in steps S51-S56, S59 and S60 Fig, and will not be repeatedly described.

At step S99, the controller 141 generates a table of settings based on the NIT and SDT Monomeric broadcast, or NIT and SDT public broadcast of the Central segment, and based on the frequency calculated in step S96. Then, the controller 80 stores the generated table settings in the internal storage device, after which the processing ends.

As described above, the public station 101 broadcasts generates NIT Central segment of the public broadcast, including NIT public broadcast and multi-segment descriptor information, and then transmits the NIT in the Central segment of the public broadcast. Then, the receiving terminal 102 receives the TS of the Central segment of each physical channel, and is consistent with the multi-segment descriptor information contained in TS, recognizes whether the Central segment segment multi-segment broadcast or not, for configuration management. This allows you to recognize information about configuring all public broadcasts.

It should be noted that, also in the system 100 transmission/reception, the receiving terminal 102 can be configured to a different segment of the broadcast, except for the Central segment of the public broadcast, to obtain SDT and register the correct name of the service table settings based on SDT.

Accordingly, when the receiving terminal 102 is configured on a different segment of the broadcast, in addition to the Central segment, the receiving terminal 102 can recognize the actual host segment broadcast among segments of the broadcast, recognizable from NIT Central segment.

For example, on Fig, the receiving terminal 102 recognizes from NIT Central segment all segments used to transmit using public broadcast stations 101-1 to 101-3, as a segment of the broadcast. However, when the receiving terminal 102 is in the area of service, the receiving terminal 102 may not take public broadcast of public stations is 101-1 and 101-3 broadcast. Therefore, even when the receiving terminal 102 is configured on a different segment of the broadcast, in addition to the Central segment, TS public broadcasts public stations 101-1 and 101-3 broadcast is not received, and will receive only SDT public broadcasting public station 101-2 broadcast, which can be actually adopted.

Thus, in this case, the receiving terminal 102 registers in the table configuration flag, indicating the possibility or lack of reception for each public broadcast, and does not show the name of the service do not accept public broadcast on the display 76. Accordingly, it is possible to prevent that when the user selects the service name shown on the display 76, public broadcasting corresponding to the service name will not be shown.

In addition, when the bit data of the multi-segment information the link is not contained in the NIT of the Central segment of the public broadcast, the receiving terminal 102 may not recognize the segment of broadcast and configured not only to the Central segment, but also to all non-Central segments. This allows the receiving terminal 102 to recognize inform the data about the configuration of other segments of the broadcast, in addition to the Central segment.

In addition, in the above-described system 30 (100) send/receive one of the Monomeric re-broadcasting and public broadcasting are performed with multi-segment broadcast, but they can both be made when multi-segment broadcast.

In addition, in the above-described system 30 (100) send/receive NIT Monomeric repeat broadcast or public broadcast can be received, for use, for registration information, such as service ID, the table settings.

In accordance with the invention, NIT, defined in the existing terrestrial digital broadcast with multi-segment descriptor information attached to it, is passed as NIT Central segment of multi-segment broadcasting, which ensures compliance with multi-segment broadcast methodology existing terrestrial digital broadcast, ensuring their interaction.

In addition, the receiving terminal 33 (102) may be implemented by adding to the conventional receiving terminal 95 detection of multi-segment descriptor information NIT Central segment multi-segment broadcast, the function is formirovaniya configuration table-based multi-segment descriptor information, etc. Thus, in accordance with the receiving terminal 33 (102), it is possible to limit the increase in cost, to provide multi-segment broadcast.

The sequence of the above-described processes Monomeric relay station 32, the receiving terminal 33, the public station 101 broadcasts and the receiving terminal 102 may be performed using hardware or software. To run a series of processing using software, a program configuring the software is installed in the computer.
