The technical field to which the invention relates

The present invention relates to the transmitter, mode of transmission, the receiver, the method and programme, and more specifically, to the transmitter, mode of transmission, the receiver, the method and program, which allows to obtain General information selection of multi-channel broadcast.

The level of equipment

In recent years, digital terrestrial broadcasting is carried out in the UHF (ultra high frequency). Physical channel digital terrestrial broadcast is divided into 13 segments, and the broadcast is intended for mobile terminals, is through the use of the bands corresponding to a single segment. Broadcast is intended for fixed terminals, such as television sets, is through the use of the bands corresponding to the remaining 12 segments (for example, see the PTL 1).

When broadcast, designed for mobile terminals, the same program as broadcast intended for fixed terminals, currently transmits in broadcast mode, and mobile terminals, the host broadcasts intended for mobile terminals, is widespread in the form of mobile phones.

In the waves of the digital terrestrial broadcasting has a lot of unused channels, in addition to the channels through which actually perform digital terrestrial broadcasts in various fields, components from 13 to 52 UHF channels. Accordingly, we studied the way that makes the best use of unused channels.

The way to implement multi-segment broadcasting using unused channels, known as a powerful way of effective use of unused channels. Multi-segment broadcasting means many Monomeric service broadcasting, which also passed through one physical channel. Therefore, when multi-segment broadcasting transmission frequency band for terrestrial digital broadcasting divided into many segments, and one or more services broadcast provided by one segment.

Existing mobile terminal, the host broadcasts intended for mobile terminals, receives information on the selection channel, which represents the information about the choice of channel, such as frequency, etc. and generates a table of choice (below called a spreadsheet channel selection).

Figure 1 shows a block diagram of the sequence of operations, illustrating the process of formation of the table, select the channel in the mobile terminal in accordance with the prior art.

At the stage S11 mobile terminal sets the given physical channel (for example, physical channel with the lowest frequency)as the destination physical channel, intended for processing. At the stage S12 mobile terminal chooses the Central segment of the target physical channel. At the stage S13 mobile terminal determines whether adopted TS (Transport stream) the Central segment of the target physical channel, and is in the process of phase S 14, determine when that TS was adopted.

At the stage S14 mobile terminal receives NIT (network information table), which is information about the network of the corresponding segment, described as NIT relevant, and SDT (table service description), which is information about the service is broadcast over the network corresponding segment, described as SDT relevant to the adopted TS. NIT is a table that includes information about the frequency for each service broadcasting is used to configure the carrier, through which is passed a certain service broadcasting, and information about the corresponding service broadcasting. SDT is a table, which includes meta-information (e.g. the name of the service) for each service broadcasting. After the process is completed at the stage S14 perform the process on stage S15.

On the other hand, when the S13 determines that TS Central segment is not adopted, the process at the stage S14 miss and perform the process on stage S15.

At the stage S15 mobile terminal determines whether all physical channels are set as a target physical channel. When the S15 determine that not all physical channels is set as a target physical channel, mobile terminal sets the following physical channel (for example, physical channel, which has the second highest frequency) as the destination physical channel on stage S16, and again executes the process stage S12. Mobile terminal repeatedly performs processing stages S12 - S16 until such time as all physical channels will not be set as a target physical channel.

On the other hand, when the S15 determine that all physical channels are set as a target physical channel, mobile terminal generates a table of channel selection is based on NIT and SDT from round S14, at the stage S17.

In particular, as shown in figure 2, the network ID, which is the ID that is specific to the network, TSID, which is the ID specific to TS, the frequency ID services specific to services broadcast, etc. all of which correspond to the segment, described in the NIT. TSID, service ID and name of the service, the corresponding ID service, etc. all of which correspond to the segment described in SDT.

Accordingly, as shown in figure 2, the mobile terminal gets the ID of services and frequency as the information channel selection NIT Central segment of each physical channel gets the name of the SDT, corresponding NIT, and correlate them with each other in the table, select the channel.

In the example shown in figure 2, because the two services broadcast, ID services which are ID1 and ID2, pass with time division through the Central segment of the physical channel 1 (physical SN 1), two ID services described in the NIT of the Central segment of the physical channel 1.

Detailed description of the invention

An implementation option

System configuration of the transmitter and receiver

Figure 4 shows a diagram illustrating the system configuration 30 transmitter and receiver, in accordance with the embodiment of the invention.

The ground station 31 broadcast performs digital terrestrial broadcasting, using the waves of the digital terrestrial broadcasting. Regional station 32-1 broadcast transmits multichannel regional broadcasting, which can only be accepted in the region And maintenance, as multi-segment broadcasting using unused channels waves terrestrial digital broadcasting.

Multichannel regional broadcasting is a Monomeric broadcasting, which is carried out between multiple parties using multiple logical channels in a particular area. A sample multi-channel regional broadcasting is a broadcast within amusement Park, which can be taken only at the amusement Park. Below multichannel district broadcast is simply called the district of the broadcast. In the following description of the district broadcasting, as an example, is presented as a multi-segment broadcasting.

Regional station 32-2 broadcast transmits regional broadcasting, which may be adopted only in the area of services, in the form of a multi-segment broadcasting using unused channels waves terrestrial digital broadcasting. Regional station 32-3 broadcast transmits regional broadcasting, which can only be accepted in the field With care in the form of multi-segment broadcasting, using unused channels waves terrestrial digital broadcasting. In the following description, when district station 32-1-32-3 broadcast't particularly want to distinguish from each other, together they are called the district station 32 broadcast.

Terminal 33 receiver is a mobile terminal that can receive broadcasts intended for mobile terminals (below called single segment of the broadcast terrestrial digital broadcasting and regional broadcast. Accordingly, as shown in figure 4, if the user terminal 33 receiver is located in the region And maintenance, terminal 33 receiver can accept Monomeric broadcast and regional broadcasts from regional offices 32-1 broadcast.

Wave of digital terrestrial broadcasting

Figure 5 shows a diagram illustrating the selection of the bands for waves of ground-wave digital broadcasts in the system 30 transmitter and receiver, shown in figure 4.

As shown in figure 5, in the system 30 transmitter and receiver, Monomeric broadcast is performed by the use of the band of the Central segment in physical channel used for terrestrial digital broadcasting of all stripes waves digital terrestrial broadcasting, and broadcasting, designed for fixed terminal, perform with the band corresponding to the remaining 12 segments.

Regional broadcasting is passed as multi-segment broadcasting by using unused channels. The maximum number of logical channels district broadcast, which can be formed by using one unused channel, is 13.

The allocation of the bands at the district broadcast transmission in an unused channel is not defined by anything specific, but when the level of importance regional broadcast obvious, district, broadcasting, with a high level of importance, can be attributed to the Central segment. In this case it is possible to allow terminal 33 receiver more satisfactorily to take the district broadcasting, with a high level of importance.

An example in which the level of importance regional broadcasting is clear, shown in Fig.6. Figure 6 regional station 32-1 broadcast represents the Central station, for which a specified area is set as the scope And maintenance. District station 32-2 and 32-3 broadcast represent local station, in which buildings or areas for entertainment within the scope established as the area In and out of service. Thus, the region And a service includes the areas In and out of service. Therefore, it is apparent that the level of importance regional broadcast to the Central station (district station 32-1 broadcast), reception area which more is higher than the regional broadcast to the local stations (district station 32-2 and 32-3 broadcast).

As shown in figure 7, we can consider three ways of obtaining information channel selection for the district of broadcasting. In the first way information channel selection is obtained by scanning the waves broadcast. In the first method, the terminal of the receiver can receive information channel select accept district broadcast only by scanning the waves of the digital terrestrial broadcasting. Accordingly, the user, who has a terminal of the receiver can automatically obtain the information channel select accept district broadcast without recognition, is there a regional broadcast, which could be adopted at the current position.

In the second way information channel selection is already loaded in the terminal of the receiver. The second method kindly requested to keep the information channel selector in the terminal of the receiver, but it's hard to keep all the information channel selection district broadcast, which is different depending on regions. Accordingly, the second method is not suitable for the district of broadcasting.

The third way information channel selection is obtained by using tools (such as data transmission over the Internet), other than broadcasting. The third way a user who has a terminal receiver must determine whether the district broadcasting, which could be adopted at the current position, and must pass a command to obtain information channel selection district broadcast. However, it is difficult to determine the regional broadcasting, which vary in different areas, changing field. Accordingly, the third method is not suitable for district broadcast.

Accordingly, the first method is used as a way of getting information channel selection district broadcasts in the system 30 transmitter and receiver. In particular, the station 31 terrestrial broadcasting and regional station 32 broadcast transmits information to select a channel by using ground waves digital broadcasting, and the terminal 33 receiver receives and stores information channel selection via the scan operation. Terminal 33 receiver selects and plays channel regional broadcasting with the specified logical channel based on the information stored channel selection.

Configuration regional stations broadcast

On Fig shows the block diagram illustrating the detailed configuration of the district station 32 broadcast.

Regional station of 32 broadcast, shown in Fig, includes the module 51 generate relevant information for the module 52 receive video, the video encoder 53, 54 module receive audio, audio encoder 55, multiplexer 56, 57 module transmitter and antenna 58.

Module 51 generate relevant information generates PSI (specific information for the program), which includes NIT and SDT regional broadcasting, and information (below called management information display)used to run a display using the browser at the district broadcast, as relevant information, and submits that the relevant information in the multiplexer 56. PSI is a generic term for tables that includes information such as NIT, PMT (table mapping program) and PAT (table Association programs)used to receive services broadcast, information about the frequency and the information used to specify the package corresponding to the service broadcasting, and information management system.

Module 52 receiving video data gets district video broadcast from the built-in HDD (hard disk drive disk), which are not shown or from an external server, and delivers the received video to the video encoder 53.

The video encoder 53 encodes video data is fed from a module 52 receive the video data on the basis of the method of coding, such as MPEG2 (experts Group of the moving image, phase 2), and passes the encoded video data multiplexer 56.

Module 54 receiving audio data gets district audio broadcast of the embedded HDD, which are not shown or external server and transmits the audio in audio encoder 55.

Audio encoder 55 encodes audio data submitted from a module 54 receiving audio data, based encoding, such as MPEG2, and delivers the encoded audio data in the multiplexer 56.

Multiplexer 56 multiplexes relevant information from the module 51 generate relevant information, video from the video encoder 53 and audio data from 55, generates TS and feeds the generated TS in module 57 transmitter.

Module 57 transmitter transmits TS, submitted from multiplexer 56, through antenna 58 by using the given segment.

NIT and SDT

Figure 9 shows a diagram illustrating NIT served in the use of the Central segment of the physical link to the district broadcast.

As shown in figure 9, when district broadcast pass through the use of the 13 segments s1-s13, components of physical channel for regional broadcasts, NIT-0 and NIT-1, described below, is passed by the use of the Central segment of s7.

NIT-0 includes the network ID, the handle multi-segment information and information (below called information TS) for TS Central segment of s7. The handle multi-segment information is a handle representing that segments s1-s13, components of physical channel, which includes Central segment s7, are segments of the multi-segment broadcasting. Information TS Central segment s7 includes TSID TS Central segment s7, the frequency of the Central segment of s7 and service ID for services broadcast of the Central segment of s7.

NIT-1 includes the network ID and information TS for segments s1-s6 and s8-s13, other than the Central segment of s7. Network ID NIT-0 and the network ID NIT-1 differ from each other. In the example shown in figure 9, the network ID NIT-0 is equal to 0, and network ID NIT-1 is equal to 1.

NIT-0 with the above configuration, passed as the actual NIT describing NIT corresponding segment, through the use of the Central segment s7, as shown in figure 10. In addition, NIT-1 is passed as another NIT describing NIT, which is information about the network segments (below referred to as off-center segments)than that of the corresponding segment of the same physical channel.

As shown in figure 10, SDT Central segment s7 passed as SDT is topical for the description of SDT corresponding segment through the use of the Central segment of s7. In addition, SDT noncentral segments s1-s6 and s8-s13 passed as SDT another describing the SDT, which is information about the service is broadcast to the network noncentral segments.

On the other hand, as shown in figure 10, NIT-1 is passed as NIT current through the use of noncentral segments s1-s6 and s8-s13, and nothing is passed as NIT another. SDT relevant segments s1-s6 and s8-s13 passed as SDT relevant and nothing is passed in as the SDT another.

Figure 11 shows a diagram illustrating the structure of the data NIT.

As figure 11 shows, the ID of the table (table_id) size 8 bits, the indicator syntax plot (section_syntax_indicator) the size of one byte, and reserved area (reserved_future_use) of size one bit consistently are located starting from the title of the NIT. When NIT NIT is a NIT, as NIT relevant ID table is a 0 x 40. When NIT is a NIT, as NIT another, ID table is a 0 x 41. When NIT is a NIT, as NIT relevant Central segment descriptor multi-segment information is described in the area reserved for the future.

After the reserved area follow not used area (reserved) the size of two bits; length of a segment (section_length) of size 12 bits, the network ID (network_ID) 16 bits are not used area (reserved) the size of two bits, and the version number (version_number) 5 bits that are consecutive. After this current following indicator (current_next_indicator) the size of the one bit sector number (section_number) size 8 bits, the last number of the segment (last_section_number) size 8 bits and reserved area 4 bits are consistently.

Length of handle network (network_descriptor_length) of size 12 bits and the cycle network size 4 bits are consistently thereafter. In the cycle network descriptors, such as a handle network name (network_name_descriptor) and the handle system management (system_management_descriptor), are for each network ID, described in the previous step. The name of the network is described in the descriptor name of network and information representing whether the network is a broadcast data or data network, described in the descriptor system management.

After the loop network consistently are reserved area the size of 12 bits, the cycle length TS (transport_stream_loop_length)cycle TS and 32 value CRC (cyclic redundancy check) (CRC_32) with a size of 32 bits. In the cycle TS descriptor list of services (service_list_descriptor), a handle to the ground system (terrestrial_delivery_system_descriptor) etc. documented for each TS. Service ID, which is the information to specify the service broadcasting and the type of services that represent the type of service broadcasting (television broadcast, multicast, broadcast, etc.), described in the descriptor list of services and information channel selection is described in the descriptor ground systems.

Processing in regional stations broadcast

On Fig shows the block diagram of the sequence of operations, illustrating the processing of transfer to the district station 32 broadcast.

At the stage when the module 51 generate relevant information generates PSI regional broadcasting and information management display relevant information and submits relevant information generated in the multiplexer 56.

At the stage S32 module 52 receiving video data gets district video broadcast from the built-in HDD, which is not shown, or from an external server and delivers the received video to the video encoder 53.

At the stage S34 module 54 receiving audio data gets district audio broadcast of the embedded HDD, which is not shown, or from an external server and delivers the received audio in audio encoder 55.

At the stage S35 audio encoder 55 encodes the audio data is fed from a module 54 receiving audio data, based encoding, such as MPEG2, and delivers the encoded audio data in the multiplexer 56.

At the stage S36 multiplexer 56 multiplexes relevant information from the module 51 generate relevant information, video from the video encoder 53 and audio data from 55 and generates TS.

In particular, the multiplexer 56 generates as TS Central segment of TS, including NIT-0 (see figure 9), as NIT relevant, including NIT-1 as another NIT, including SDT corresponding segment as SDT relevant and including SDT noncentral segments as SDT another. Multiplexer 56 generates as TS noncentral segments TS, including NIT-1 as NIT relevant and including SDT corresponding segment as SDT relevant. Multiplexer 56 delivers TS generated in the module 57 transmitter.

At the stage S37 57 module transmitter transmits TS supplied from a multiplexer 56, through antenna 58 through the use of a given segment and completes the processing flow.

Detailed configuration of the terminal of the receiver

On Fig shows the block diagram illustrating the detailed configuration of the terminal 33 receiver presented on figure 4.

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

Tuner 72 selects the channel based on the information channel selection supplied from a controller 80, and accepts TS Monomeric broadcasting or local broadcasting through the given logical channel, through the antenna, 71 out of the ground station 31 broadcast or from the district station 32 broadcast. Tuner 72 delivers adopted TS demuxer 73.

The demultiplexer 73 shares TS supplied from a tuner 72, video, audio, information, control the display and information PSI. The demultiplexer 73 takes video in video decoder 74 and delivers the audio in audio decoder audio 77. The demultiplexer 73 submits information to control the display in the browser 79 and transmits information in PSI controller 80.

Video decoder 74 decodes video supplied from demultiplexer 73, on the basis of the method corresponding to the video encoder 53, controller 80 and feeds the decoded video data in the module 75 choice.

Module 75 selection selects the video data is fed from a decoder 74, or video data submitted from a browser, 79 controller is 80, and delivers the selected video data in the module 76 display. Module 76 display shows an image of a single segment of broadcasting or local broadcasting on the basis of video data supplied from 75 module selection.

Audio decoder audio 77 decodes audio data supplied from demultiplexer 73, on the basis of the method corresponding to 55, controller 80 and feeds the decoded audio data in loudspeaker 78. Loudspeaker 78 displays a sound that matches the audio data from audio decoder 77 as sound Monomeric broadcasting or local broadcasting.

The browser 79 analyzes the information to control the display of supplied from demultiplexer 73, generates video, and sounds generated by the video data module 75 choice.

The controller 80 consistently delivers the information channel selection the Central segment of each physical channel ground waves digital broadcasts in the tuner 72. The controller generates 80 table of channel selection is based on NIT relevant and current SDT Central segment of each physical channel supplied from demultiplexer 73, or NIT relevant, NIT another, SDT relevant and SDT another. Controller 80 stores the generated table of channel selection in the built-in memory (not shown).

The controller delivers 80 names registered in the lookup table of the channel, in the browser 79 in response to a command from the user and displays the name of the service module 76 display. The user selects and sends commands to the service name for a service broadcasting, which should be viewed when the name of the service that is displayed on the module 76 display. Controller 80 reads the choice of the channel corresponding to a service name, which must be seen from the table, select the channel on the basis of selection commands and gives few details select the channel to tuner 72.

The controller controls 80 scaler 74, 75 module selection, audio decoder 77 and browser 79 on the basis of information PSI supplied from demultiplexer 73. In particular, the controller controls 80 scaler 74 and audio decoder 77, for example, for a synchronization of video signals output from the video decoder 74, and audio output from the audio decoder 77, with each other.

Method of formation of tables channel selection

As shown in position And Fig, terminal 33 scans the Central segment of each physical channel ground waves digital broadcast sequentially from low frequency. In particular, the tuner 72 terminal 33 receiver selects the Central segment of each physical channel sequentially from low frequency and receives TS Central segment.

Accordingly, NIT and SDT Monomeric broadcast, transmitted through the use of Central segments 91 and 93, get out NIT relevant and current SDT TS Central segments 91 and 93 of physical channels, which are terrestrial digital broadcasting.

On the other hand, NIT and SDT district broadcast data transmitted through the use of the Central segment of 92-1, get out NIT relevant and current SDT TS Central segment of 92-1 physical link, for hosting the regional broadcasting. NIT and SDT district broadcast, placed in four noncentral segments 92-2-92-5 receive from another NIT and SDT another TS Central segment of 92-1. Selection table of the channel, including the information channel selection for single segment broadcast and regional broadcasts, form, using NIT and SDT, obtained in this way.

As described above, because NIT and other SDT another, and NIT relevant and current SDT located in the TS of the Central segment of 92-1, terminal 33 receiver can receive NIT and SDT all district broadcasts physical channel corresponding to the Central segment 92-1, only continuous scanning of the Central segments of the physical channels. Accordingly, the terminal 33 receiver can generate a table of channel selection, which includes information channel selection with Monomeric broadcast and district broadcast within a short period of time. As a result it is possible to quickly give you the names of services for selected services broadcast.

On the other hand, the scan for the formation of a table, select the channel, when another NIT and SDT another are not in the TS of the Central segment shown in the position to Fig. Thus, as shown in position on Fig when the terminal of the receiver recognizes that the adopted TS TS is a Central segment of the multi-segment broadcasting handle-based multi-segment information NIT relevant terminal receiver must sequentially scanning TS noncentral segments and get NIT relevant and current SDT noncentral segments. Accordingly, in this case, the scan time is extended, and, thus, this approach is not effective.

On Fig shows a diagram illustrating the existing terminal 100 receiver which does not cover regional broadcasting, and the terminal 33 receiver, which receives terrestrial digital broadcasting in the system 30 transmitter and receiver.

The existing terminal 100 receiver successively scans the Central segments of physical channels from low frequency, similar to terminal 33 receiver, and generates the lookup table of the channel. However, because the terminal is 100 receiver does not cover regional broadcasting, multi-segment descriptor information NIT actual located in the TS of the Central segment of the physical channel, in which is placed the district broadcast is neglected. Accordingly, 100 terminal of the receiver does not lead to erroneous operation, but cannot get another NIT and SDT another.

As a result, when the terminal is 100 receiver receives terrestrial digital broadcasting in the system 30 transmitter and receiver, a table, select the channel form of NIT and SDT Monomeric broadcast and regional broadcast of the Central segments of physical channels, as shown in Fig.

And, Vice versa, since the terminal 33 receiver covers regional broadcasting, the terminal of the receiver can recognize the handle multi-segment information NIT actual located in the TS of the Central segment of the physical channel, in which is placed the district broadcasting, and can get another NIT and SDT another. As a result, the terminal 33 receiver produces a table of channel selection is based on NIT and SDT all Monomeric broadcast and district broadcast, posted in the physical channels.

On Fig shows a diagram illustrating examples table, select the channel that is formed by the terminal 33 receiver, and tables select the channel that is formed by 100 terminal of the receiver, in the example shown in Fig.

As shown in position And Fig, first name services "Monomeric services 1", ID services "ID1", and the frequency F1 Monomeric broadcast allocated to the Central segment of the first physical channel is recorded in the table, select the channel that is formed by the terminal 33 receiver.

A service name from "regional services 1" to "regional services 5", ID services from "ID2" to "ID6" and frequencies from "F2" to "F6" district broadcast, located in five segments second physical channel, register after that.

Then register the name of the service "single segment service 2", ID services "ID7", and the frequency of "F7" Monomeric broadcast, placed in the Central segment of the third physical channel. After that, similarly to register the facility name, ID services and frequency Monomeric broadcast allocated to the Central segment of the fourth physical channel and regional broadcasting in seven segments fifth physical channel.

On the other hand, as shown in position on Fig, similarly to table select the channel that is formed by the terminal 33 receiver, the name of the service "single segment 1", ID services "ID1", and the frequency F1 Monomeric broadcast allocated to the Central segment of the first physical channel is recorded in the table, select the channel that is formed by 100 terminal of the receiver.

Then register the service name "district 1, service ID "ID2" and frequency F2 district broadcast allocated to the Central segment of the second physical channel.

Similarly to table select the channel that is formed by the terminal 33 receiver, then register the name of the service "single segment service 2", ID services "ID7" and frequency "F7" Monomeric broadcast, placed in the Central segment of the third physical channel. After that, similarly to register a service name, service ID and frequency Monomeric broadcast, placed in the Central segment of the fourth physical link, and regional broadcasts, located in the Central segment of the fifth physical channel.

As described above, when an existing terminal 100 receiver receives terrestrial digital broadcasting in the system 30 transmitter and receiver, the terminal is 100 receiver does not cover regional broadcasts and, thus, could not register information channel selection district broadcast noncentral segments in the table, select the channel. However, the existing terminal 100 receiver can receive information channel selection Monomeric broadcast, transmitted from ground stations 31 broadcast. Accordingly, terrestrial digital broadcasting in accordance with the invention does not prevent the admission of Monomeric broadcasts in the existing terminal 100 receiver.

Processing in the terminal of the receiver

On Fig shows the block diagram of the sequence of operations that illustrates the process of formation of the table channel selector in the terminal 33 receiver. The process of formation of the table channel selection begins, for example, when the user passes command to retrieve the table of the channel selection.

At the stage S51 controller 80 sets the given physical channel (for example, physical channel with the lowest frequency) as the destination physical channel, intended for processing. The controller delivers 80 frequency of the Central segment of the target physical channel as the information channel selection in tuner 72.

At the stage S52 tuner 72 chooses the Central segment of the target physical channel based on the information channel selection controller 80.

At the stage S53 tuner 72 determines whether adopted TS Central segment of the target physical channel and runs a process of stage S54, determine when that TS Central segment of the target physical channel was accepted.

At the stage S54 demultiplexer 73 allocates NIT relevant and current SDT of the TS of the Central segment of the target physical channel, adopted by the tuner 72, and receives NIT relevant and current SDT.

At the stage S55 demultiplexer 73 determines whether the accepted TS Central segment of multi-broadcast-handle-based multi-segment information NIT relevant obtained during the S54.

When determining the stage S55 that the adopted TS TS is a Central segment of the multi-segment broadcasting demultiplexer 73 allocates another NIT and SDT another of the TS of the Central segment of the target physical channel and receives another NIT and SDT another phase S56. Then run the process at the stage S57.

On the other hand, when the S53 determines that TS Central segment of the target physical channel was not adopted, or when the define phase S55 that adopted the TS TS is the Central segment of multi-segment broadcast, perform the process on stage S57.

On the other hand, when the S57 determine that all physical channels are set as a target physical channel controller 80 creates a table of channel selection is based on NIT relevant and SDT another, or NIT relevant, NIT another, SDT relevant and SDT another received by the demultiplexer 73 on stage S59.

As described above, regional station of 32 broadcast generates NIT district broadcast as multi-segment broadcasting and passes TS, including NIT relevant, describe NIT Central segment, and another NIT describing NIT noncentral segments, using the center of the segment. Accordingly, only by receiving TS Central segments of physical channels district-broadcasting terminal 33 receiver can recognize information channel select all regional broadcast of the NIT relevant and another NIT included in taken TS.

Since the district station 32 broadcast transmits NIT noncentral segments as NIT another defined in existing terrestrial digital broadcast transmission, the regional broadcasting may be agreed with the method and system of the existing terrestrial digital broadcasting, ensuring, thus, their mutual interoperability.

And, Vice versa, when NIT noncentral segments along with NIT Central segment is passed as NIT relevant terminal 33 receiver may cause erroneous operation. This is because not defined in existing terrestrial digital broadcast transmission that NIT actual includes NIT segments than the corresponding segment.

Terminal 33 receiver accepts TS of the Central segment of the district broadcasts transmitted from the regional station 32 broadcast, and allocates NIT relevant and NIT different from TS. Terminal 33 receiver creates a table of channel selection is based on NIT relevant and NIT another. Accordingly, only by receiving TS Central segments of physical channels district-broadcasting terminal 33 receiver can recognize information channel selection entire district broadcast, transmitted on the basis of NIT relevant and another NIT included in the adopted TS.

Terminal 33 receiver can be implemented by adding the allocation function as NIT relevant and NIT another of the TS of the Central segment of multi-segment broadcasting and recording of information selection of multi-channel broadcasts in the table of channel selection is based on NIT relevant and NIT another in the existing terminal 100 receiver. Accordingly, in accordance with the terminal 33 receiver becomes possible not to allow an increase in the cost required for the coverage of regional broadcasting.

In the above description SDT another feature of the TS of the Central segment. However, when there is no need to display the names of the services at terminal 33 receiver, SDT another could not be placed. For example, when the user passes command on an object, select the channel, passing the move command of the physical link by using the up and down buttons at terminal 33 receiver, SDT other may not be posted.

The description above one another NIT place in all of noncentral segments. However noncentral segments can be divided into many groups (e.g. groups in each district station 32 broadcast, as the source of the broadcast), and NIT another could be placed for each group.

The processes described above station 32 district broadcast and terminal 33 receiver can be performed with use of hardware or software. When the processing is carried out by means of software programs comprising the software, installed in the computer. Here are examples of a computer that includes your computer, collected in the form of specialized hardware, and a personal computer, made with the possibility of various functions, by setting different programs in it.
