The technical field to which the invention relates

The present invention relates to the transmitting device and the method of transmission for signal transmission in the transmission system, with many carriers. In addition, the present invention relates to the receptor and the method of admission to receive signals transmission system, with many carriers. Moreover, the present invention relates to a system of transmission of signals from multiple carriers, computer program and a non-volatile medium of information.

The level of technology

Digital signals are sent in applications such as digital video broadcasting. Standards such as the so-called standards DVB, have existed since the 1990s and provides for a number of different modulation schemes, such as diagrams quadrature amplitude modulation (QAM) or multiplexing with orthogonal frequency division multiplexing (OFDM) for broadcasting services, along with the formats for the transmission of accompanying management data and metadata. These standards define as radio frequency (RF) technology, which will be used to transfer the data and the way in which the data representing the different services broadcasting, organized in packets and streams for transmission.

DVB comprehensively documented elsewhere, so below will be presented only a brief description with reference to the standards that relate to the transfer of services of cable broadcasting, although, of course, it should be noted that such review may be (for example) to digital satellite services and terrestrial broadcast services.

In basic terms, video data, audio data and accompanying data corresponding to the broadcast program, are multiplexed into the flow of the program (PS) MPEG-2. One or more PS multiplexed for the formation of a transport stream (TS), created as a sequence of data packets of a fixed length. Bit rate TS can be in the range between approximately 6 Mbit/s and 84 Mbit/s depending on the parameters, such as the modulation scheme used (for example, 16QAM - 4096QAM) and bandwidth broadcast channel that will be used for the transmission of TS.

According to the existing technology, one broadcast channel (with the bandwidth from multiple MHz to 8 MHz) carries one TS. TS includes packet data program (video, audio, etc) and batch control data that define the various programs that are migrated using TS (so-called data (PSI/SI). As an elementary part of the data PSI/SI also postponed the so-called network information table (NIT), which provides information on the physical network, such as the frequency of the channel, sender, services, and name services. These details are described, in particular, in the document "digital video Broadcasting (DVB); Specification for service information (SI) in systems DVB - Document And 38 DVB, January 2011" (Digital Video Broadcasting (DVB); Specification for Service Information (SI) in DVB systems - DVB Document A3 8, January 2011). The most recent physical elements of DVB second generation, such as DVB-C2 (which is described in the document "digital video Broadcasting (DVB), the Manual on implementation of digital cable transmission systems of the second generation (DVB-C2), Document 147 DVB November 2010" ("Digital Video Broadcasting (DVB); Implementation Guidelines for a second generation digital cable transmission system (DVB-C2) - DVB document A 147, November 2010)and DVB-T2, overcome the limitation of converting one TS in one physical level using so-called, approach PLP (channel physical layer), i.e. one signal physical layer usually contains more than one data stream (TS).

The EP 2131521 A1 and the EP 2131522 A1 disclosed transmitter digital signals, in which each of the many data streams transmitted using modulation of the corresponding frequency band within one of the groups of frequency channels, each of the bands takes no more than the configured maximum bandwidth that is less than or equal to the width of the channel bandwidth. The transmitter has a tool for the transfer of the relevant provisions of frequencies within each frequency channel, one or more items of information about the band, which determines the frequency band corresponding to all the streams of data carried within this frequency channel, and one or more items to be placed so that any part of the frequency channel is equal in magnitude given maximum bandwidth, included at least one item of information about the band. In addition, disclosed appropriate receiver digital signals.

There is a growing demand not only for the numerous digital television services, but also on higher-quality services (in respect of the picture and audio permission). This demand is putting pressure on digital payload carried by each channel. Therefore, the continuous objective is the effective and flexible use of the existing broadcast spectrum.

These aspects of the present invention are based on the idea of reducing the expenses on the alarm system and quick setup of the receiver with the use of the indicator type of frequency tuning, which indicates the receiver what type of frequency settings shows frequency display. Therefore, you can flexibly use the frequency display, i.e. a different frequency settings you can record in this indicator frequency settings (which is also seen as one of a series of descriptors, and only a short type indicator frequency of settings needed for sending information to a receiver frequency tuning the receiver actually reads from the mentioned indicators of frequency tuning.

Of course, this mechanism alarm can also be used to gain an advantage compared to other transmission systems that use other staffing patterns or other display data flows in frequency channels. In such a personnel structure of one or more traffic flows display in one or more sections of the data (also in the future are referred to here as frequency bands), each of which (in the case of more than one slice of the data) covers only part of the full bandwidth frequency channel. The options for implementing information about the band such known systems is also called the descriptor of the delivery system.

Realization of the invention

As shown in figure 1, the system of transmission of digital signals contains the transmitting device 10 and receiving device 20, which are connected by a line 30 of communication. In this example, the communication line is wired communication line", a term which covers the conductive wires and fiber-optic), and system (1) is for the provision of cable TV services. In General, except in cases where there are differences, the device operates in accordance with the standard DVB-C2, which is seen here as a model of option implementation.

In addition, there is also a subsidiary reverse channel 40, with the help of which information, such as a purchase or read statistics, can be transferred from the receiver to the transmitter. Reverse channel is known and would not further described here.

These technologies are not limited to cable systems. Relevant technologies can be used in other systems of transmission, such as terrestrial or satellite system.

The transmitting device contains a number of programmable multiplexers 100, each of which is programmed on the flow of data. These multiplexed video, audio and data streams belong to the program in the program stream (PS) MPEG-2. PS multiplexed with transport multiplexer 110 using PS for other programs for the formation of a transport stream (TS) MPEG-2. TS is the primary digital stream, which is tolerated by the system and can have a bit rate usually in the range of approximately 6 to 84 Mbit/sec

TS multiplexed with other TS (or other input streams, such as the so-called generalized encapsulated flows, generalized continuous streams or generalized packaged flows fixed-length) and network information (which will be described below) via a multiplexer 120, and the resulting data are served on the encoder and the modulator 130.

The encoder and the modulator 130 cover features such as packaging, coding channel interleaving data (time and/or frequency), convert word length, differential encoding, encoding QAM, elaboration of the frame filtering baseband and radio frequency (RF) modulation, such as OFDM-modulation, in which each thread payload is transferred modulated groups (usually) adjacent carriers. Except where described, these functions correspond to the known functions of the transmitting device DVB-C2. In practical system may be multiple transmitting devices associated with a block of Association to develop combined modulated RF signal. Modulated RF signal cable 30 for transmission in one or more (usually large number) receivers 20.

The transmitting device 10 is running controller 140. Below will describe the functions performed by the controller 140 (for example, preparation of NIT and data on the strip). The receiving device, 20 will be described in more detail below, in particular, with reference to the Fig.7. While it is enough to note, that the receiving device works under the control information for demodulation and decoding of the required data stream, such as, in particular, the TS - from the transmitted signal.

In the process, the transmitting device 10 is working with a number of frequency channels. They are usually within the range from about 47 to approximately 862 MHz. But these technologies can be applied to a location that has only one frequency channel. Within each channel, data is transferred using OFDM-modulation many carriers.

Although previous systems, channels have a fixed bandwidth, for example, 8 MHz, with each channel was near frequency (with a small strip) with the following channel, in the newer system, the permitted use of channels with different width of the passband (arbitrary bandwidth over to 7.61 MHz, for example, 8, 16, or 32 MHz). However, the bandwidth of the receiver (and, respectively, the maximum allowed bandwidth, with the help of which you can transfer one data flow payload, such as TS) remains the same as in previous systems, for example, 8 MHz. In other words, a given receiver bandwidth is less than or equal to the width of the channel bandwidth. Technology also allows migrate a number TS or other types of payload within the same channel. Figure 2 illustrates the previously proposed frame data, will be used to explain how this technology works.

In this case, the time is shown below in the vertical direction, and frequency - in the horizontal direction. Frame 300 data is (in this example), the bandwidth of 32 MHz and starts with a header 310. In the header 310 many elements 320 L1 data included in various provisions of the frequencies within the channel. The specific contents of the L1 data will be explained below, but referring to the example of figure 2, it should be noted that as an example, eight such elements are executed within the channel 32 MHz. In other words, each example L1 data is carried out by a group of neighboring OFDM-carriers, which, taken as a group, occupy bandwidth of 4 MHz (in other systems to 7.61 MHz equivalent to a maximum bandwidth of data slice), although in a more General sense, each element may be less than the bandwidth of the receiver, and will therefore the higher the number of elements, if the bandwidth of each element less. In other variants of implementation, data elements L1 can also take greater bandwidth, even bandwidth in excess of 8 MHz.

Eight data elements L1 (in this example) within the same channel 32 MHz preferably are identical and, for convenience, preferably transmitted at the same time. The reason L1 data transmitted in a bandwidth of not more than the bandwidth of the receiver, is that in any place where the band receiver 8 MHz is aligned within the channel 32 MHz, the bandwidth of the receiver is limited to cover at least one full data element of L1.

Figure 3 shows a schematic example of image time-frequency domain structure frame or a combination of 300', which is used in accordance with the standard DVB-C2, where you can use the present invention. The structure of the 300' frame covers the entire 24 bandwidth transmission in frequency direction and contains at least one (or, at least, two or, at least, three) signal combination 31 (which correspond to elements L1 data mentioned above), situated next to each other frequencies in the frequency direction, each of which carries identical or almost identical signaling information displayed on the relevant frequencies and have the same length. In the example shown in fig.z, the first time slot entire strip 24 bandwidth transmission is divided into four signal combinations 31, but suitable can be any other higher or lower number of the signal combinations.

The length of pilot signals (number of carrier frequencies allocated band pilot signals) is mostly the same for each signal combinations. Length or band 39 bandwidth of a signal combinations of 31 may be the same as the band 38 bandwidth, you can configure the tuner receiver. However, bandwidth transfer, you can configure the tuner to the receiving device can be greater than the length of the signal combinations 31. Conversion of the signal data and pilot signals in carrier frequencies during the conversion from the frequency to the staging area is run by the frequency conversion in time.

Each signal combination of 31 contains, for example, the allocation of signal combinations 31 within the frame. For example, each signal combination 31 in each frame 300' has and carries identical signaling information. Signal data are, for example, signal L1 data that contain all the information about the physical channel, which is necessary to the sink device to decode the received signals. However, any other suitable signaling information may be contained in the signal combinations 31. Signal combinations 31 may, for example, contain the allocation of appropriate segments 32, 33, 34, 35, 36 data to the receiving device knows where to find the necessary data segments to tuner receiver could tune in to the appropriate location in order to take the necessary data segments. Alternatively, as mentioned above, each signal combination of a frame can contain identical signaling information, and the location of the corresponding signal combinations within the frame is indicated in various ways, such as through the sequence of pilot signals signal combinations or by the information encoded in the protection belts, etc. As set out above, each signal combinations 31 may contain information about each combination of data contained in the frame. This information may include the length of the combination of data, number and/or the location of the pilot signals contained in the combinations of data and/or position settings (for example, the bandwidth settings, the beginning of bandwidth or similar) and/or any other appropriate information. Thus, information about the length of the data patterns is expressed, for example, in terms of or belongs to a minimum lengths combinations of data. However, in order to reduce the inefficient use of each signal combination of 31 should contain information on a part or some combination of data, such as, but not limited to those that are within (or located in or near) the frequency bands in which are located a signal combinations 31. In the example shown in figure 3, the first signal combination of 31 in the frame may contain information on combinations of 32 and 33 of the data (and the next time, combinations 32', 32"... 33', 33" data etc). The second signal combination in the frame may contain information on a combination of 33, 34 and 35 of the data (and the next time, combinations 33', 33"... 34', 34"... 35', 35" data etc).

As mentioned above, the first signal combinations of 31 may also contain a provision setting, that is, the frequency bandwidth of the receiver, such as a receiver 63, will be configured for the receipt of the relevant combinations of data. This position settings can be, for example, signal as a center for bandwidth settings, beginning bandwidth settings or any other suitable provisions frequency. This has the advantage that the length (in the frequency direction) combination may vary from frame to frame within the current bandwidth settings without the need or demand configure the receiver from frame to frame. In other words, by means of the alarm and the provisions of the settings in the first signal combinations 31, the receiver can easily cover the combination of data from different length within the current bandwidth settings. In addition, such an implementation would have the advantage that you will not need to provide protective strip (in the frequency domain) between adjacent bandwidth transmission channels. Each channel bandwidth transmission (each channel bandwidth, transmission, for example, has lots of bandwidth settings) contains signal combinations in which each signal combinations, for example, has the identical (or almost identical signal data). The signal data in the first signal combinations 31 in the adjacent bands channel bandwidth of transmission, however, may be different. Thus, having the information about the beginning of bandwidth settings for each corresponding receiver, which is present in the signal data of the first signal combinations 31, you can achieve a clear and unambiguous allocation of the first signal data respective receiver, and therefore protective strip between neighbouring bandwidth of the transmission channel will no longer be necessary. Furthermore, due to the position signaling settings, you can avoid setting the receiver the position in which part of the first type of signal combinations and part of the second type of signal combinations are accepted within the bandwidth settings, whereby part cannot be reordered or , because they contain a varying signal content. An additional feature is that the information is incorporated into the signaling data from the first signal combinations 31 if the tag is present in the following combinations of data. Substantially embodiment, the label always has length of the minimum combination of data or a multiple of it. In this case, the label can be always treated as a combination of data from a logical point of view. Inclusion of information relating to the provisions of labels signal data has the additional advantage that the receiver knows that, for example, permanent pilot signals are present on the edges of the label in the neighboring combinations of data, by which decreases the bandwidth of the data of these combinations of data.

Thus, as shown in figure 3, each frame preferably contain at least two data elements L1 (also called signal combinations), which are located next to each other in the frequency direction, and at least two combinations of data (data blocks displayed on different frequency bands)that follow, at least, two signal combinations in the temporal direction in the time slot that directly follows the temporary slot, in which there are at least two signal combinations. Each of the combinations of data, following the signal combinations, respectively, follows other data patterns that follow the time slots in the temporal direction, where all combinations of data, following each other in a temporary area, have the same structure in the frequency direction, and each of at least two signal combinations and combinations of data contain many of the carrier frequencies. Such a structure of the frame, as well as the formation and use of such frames, are described in more detail in the above-mentioned DVB-C2 and in numerous patent applications for the same applicant, for example, in the United States 2010/0034219 A1, the description of which is included here as a reference.

Many data elements L1 should not (in joint consideration) to fill the entire width of the channel bandwidth. Between them can be frequency intervals and shelterbelts. There are still two route to the receiver, which determines the location of the channel. One passes through NIT (network information table), and another by means of a frequency sweep, as described above.

The transmitting device, 400, according to the present invention, is schematically represented in figure 6. It contains modulator 410, which modulates each of the many data streams for carriers frequencies of the corresponding frequency band in one group of one or more frequency channels, each of the bands takes no more than the configured maximum bandwidth that is less than or equal to the width of the channel bandwidth. In addition, the transmitting device contains 400 generator 420 information about the band, generates information on the band, which determines the frequency band corresponding to all the streams of data carried within one frequency channel, and the information about the band includes frequency display, showing the frequency and type indicator frequency settings, indicating the type of frequency settings specified in the mentioned indicator frequency settings, where the above-mentioned type is selected from the group consisting of, at least, the first type, showing the frequency bandwidth, and the second type, showing the center frequency of the frequency channel. Moreover, the transmitting device contains 400 transmitter 430, which transmits mentioned data streams, modulated on carriers frequencies, and one or more elements referred to information about the band in the relevant provisions of frequencies within each frequency channel.

The receiving device to 500, according to the present invention, is schematically represented in the Fig.7. It contains a receiver 510, which configures the bandwidth of the receiver frequency channel to accept, from the frequency of the channel, an item of information about the band, and information about the band determines frequency band corresponding to all the streams of data carried within the frequency of the channel, and the information about the band includes frequency display, showing the frequency and type indicator frequency settings, indicating the type of frequency settings specified indicator frequency settings, where the above-mentioned type is selected from the group consisting of, at least, the first type, showing the frequency bandwidth, and the second type, showing the center frequency of the frequency channel. In addition, the receiver contains 500 device 520 read information about the band, which reads the information about the band and extracts the frequency bands given frequency band through an assessment of the mentioned indicators such as frequency settings and the corresponding indicator of frequency tuning. Receiver 510 configured to tune frequency settings specified read an indicator of frequency tuning, if the indicator type frequency setting specifies the second type frequency settings, or using additional information from the configuration in case the indicator type frequency settings shows the first type of frequency tuning.

On Fig.8 schematically in more detail the receiving device to 500'. Signal cable, served on the receiver 510, which contains tuner (having in this example, the bandwidth of 8 MHz, although it can be adjusted as described below), QAM demodulator and decoder channel, which performs such famous operations as a differential encode, convert word length, etc. to generate the output. Data signal output receiver 510 data, is served on the decoder 530 and detector 540 parameters associated with the storage device 550 to store your settings.

Detector 540 options performs the function of detecting the details about the channel of NIT or from the scanner and detection details TS from the L1 data, and, thus, preferably includes device 520 read information about the band, which is shown in a more General form in the flowchart in figure 9. All of these details are stored in a storage device 550 to store settings and are used to control the receiver 510 data. Decoder 530 performs decoding of the required flow PS immediately after the installation of the corresponding parameters of the receivers.

Receiver 510 data can have different bandwidth limits. For example, the receiver 510 of the data bandwidth, which is between 8 MHz and 7 MHz - perhaps to take advantage of existing compatibility with the different elements of previous systems of DVB-C. This feature can be actually used in conjunction with these technologies, so as L1 data have certain parameters for the reception of the required data flow, data receiver can set the bandwidth of the receiver on the lowest (or just low) installation (among those values that are available receiver data), which still covers the required flow data, given of course, the so-called decline, which represents a reduction in the sensitivity of the data on the edges of the bandwidth of the receiver of the data. Where the use of such a feature, the receiver of the data can, for example, set the bandwidth on the contrary to a higher level (if it is really necessary, given the bandwidth of each element in L1 data whenever data L1 especially required for access.

Below is a more detailed explanation of the first variant of the implementation of the present invention. Information about the band, in this embodiment, included in the so-called handle the delivery system, as presented below in table 1. This descriptor delivery systems used in the circuit of the table TS network information to describe the transmission of DVB-C2.

It should be noted that information on the frequency settings Slice of the data in alarm L1, as well as in the delivery system C2 should be updated synchronously.

The Central frequency of C2_System used by head stations (transmitters) C2, which cannot update information on the frequency settings (data slice) in delivery system C2 and alarm L1 synchronous manner. C2_tuning_frequency is the Central frequency of C2 system, and it requires to be able to make the full Header. The receiver must be assessed alarm L1 in the header to obtain knowledge about the final position settings.

Below is a brief discussion of several different implementations of the above variants of the transmission system according to the present invention. In the transmission of only 8 MHz center frequency C2_System (C2SF) and frequency of data Slice (DSTF) are equivalent, as shown in figure 9. They do not depend on the number or position data slices and only require one frequency that is needed to further alarm (not both). Preferably, DSTF is the signal, and C2_tuning_frequency_type is set to "00".

In the transmission system, which has a bandwidth of more than 8 MHz C2SF normally located in the centre of the strip and is different from DSTF, as shown in figure 10. The frequency of data Slice (DSTF) also differs depending on whether you need slice 1 data or slice 2 data. Usually, any C2SF or DSTF may be the signal. Alarm DSTF useful to reduce the time demodulation slice 1 or 2 data, since the receiver can switch directly to a slice of the data without having 2-stage of the configuration process. In this case C2_tuning_frequency_type is set to "00".

Sometimes, however, the head of the station cannot upgrade alarm L1 and handle delivery system synchronous manner, for example, in the case of the head stations of low-cost or S2 signals with dynamic data. Then, the frequency Slice of the data may not accurately signal, so instead of it signal should C2SF. In this case C2_tuning_frequency_type is set to "01".

In the transmission system, which has (dependent) static data segment (DSDS), Central frequency of the System S2 (C2SF) is usually located in the heart of 8 MHz bandwidth (or more), as shown in figure 11. The frequency of data slice (DSTF) for the dependent static data slice is approximately 4 MHz from the edge of the bandwidth. In this case, the receiver first decodes the Central frequency of C2 System to decode all the parameters alarm L1 prior to configuring the frequency Slice of the data. In this case, C2SF (or different frequency settings) is the signal, and it should be noted that it represents the frequency DSDS, that is a special case in which C2_tuning_frequency_type is set to "10".

Preferably, the embodiment handle delivery system includes at least the elements C2_tuning_frequency, plp_id and data_slice_id to the receiving device was able to successfully configured. C2_tuning_frequency used to avoid scanning each time after making a dynamic process or save. plp_id used to precisely determine a unique PLP. The conclusion concerning the data_slice_id you can do the analysis and processing of the entire alarm L1. However, this requires, in reasonable quantities, software processing. Therefore, one cannot avoid the 2-step configuration process if the frequency is not explicitly signal. C2_system_id not needed if the frequency is the signal, and when plp_id is unique in the system S2.

On fig.12 shows a diagram of the sequence of operation of the transmitting device. Stages of 600 and 610 performed (in this example) using the controller 110, which produces information about the channel (corresponding to the given NIT described above) and information elements on the page (the corresponding data elements L1 described above). It should be noted, that the elaboration of the data NIT is arbitrary; channels can be identified instead sweep frequency. At the stage of 620 these data is transferred (this step is executed by the encoder, and the modulator 130).

On fig.13 shows the sequence of operations of all variants of route of administration, according to the present invention, contains the following stages. Step 700 represents a phase alignment bandwidth of the receiver with a frequency channel to take from this frequency channel, an item of information about the band, and with such information about the band determines the frequency band corresponding to all the streams of data carried within this frequency channel, and the information about the band includes frequency display, showing the frequency settings, and type indicator frequency settings, indicating the type of frequency settings specified in the mentioned indicator frequency settings, where the above-mentioned type is selected from the group consisting of, at least, the first type, showing the frequency bandwidth, and the second type, showing the center frequency of the frequency channel. Stage 710 is a stage reading of the aforementioned information about the band and recovery tuner frequency bands given frequency band by assessing the mentioned indicators such as frequency settings and the corresponding indicator of frequency tuning.

Then, at the stage 715 evaluate type indicator frequency settings to show whether the indicator type of frequency tuning first or second class (or even a third type, which is used in some versions of frequency tuning. In the case of the first type, the receiver recognizes that it is configured for bandwidth and that it is already configured to the correct frequency and can directly read (phase 720) data payload in the band, the tuned. In the case of the second type, the receiver knows what he is set on the Central frequency of the channel, but for the settings you want more information about setting up, which then preferably removed by stages 725 of signaling data L1, as described above. Through the use of this additional information about configuring the receiver returns to the stage 730, after which the receiver reads (phase 720) data payload in a frequency band which is now configured receiver. In the case of the third type, the receiver recognizes that it will be configured with a static frequency band, but first needs additional information about configuring the settings for this static frequency band, which then, preferably, retrieved on stage 725 of signaling data L1, as described above. Through the use of this additional information about configuring the receiver returns to the stage 730, after which the receiver reads (phase 720) data payload in a frequency band which is now re-tuned.

Below, a more detailed explanation of the second variant of the implementation of the present invention. Moreover, in this embodiment, information about the band included into the delivery system, and also provides a General explanation provided above with respect to the first option implementation. Handle delivery system for implementation of the second option is shown below in table 5.

Description

the final frequency settings C2

you must reconfigure the information about the alarm L1

'The final frequency settings C2' is a default option for C2 systems. Field C2_tuning_frequency passes frequency slice of the data referenced by plp_id. C2_tuning_frequency for a particular Slice of the data is the sum of the parameters alarm L1 START_FREQUENCY and DSLICE_TUNE_POS. It should be noted that information on the frequency settings Slice of the data in alarm L1, as well as in the delivery system S2, should be updated synchronously.

A value of 'you must reconfigure the information about the alarm L1' indicates that the receiver C2 need to re-tune to their final positions settings, based on the specific information about configuring Slice of the data in alarm L1. Both cases require the 2 phase approach settings.

In the first case C2_tuning_frequency is a center frequency of the C2_system. This option is used by a parent stations C2 who cannot update the information on frequency settings Slice of the data in the system of delivery of C2 and alarm L1 synchronous manner. C2_tuning_frequency is the Central frequency of C2 system, and it is required for the adoption of the full Header.

In the second case C2_tuning_frequency is a starting position settings for (Dependent) Static data slice: a Slice of the data that will be , representing (dependent) (main cut) (see above is a guide to the implementation of DVB-C2, TS 102991, section 10.2). In the case of the settings on (Dependent) Static slice of the data, we cannot guarantee that the receiver can decode signaling L1 to its final position settings. Therefore, the receiver must first tune in to signal the start C2_tuning_frequency, where given the full Header. This frequency is usually a center frequency of C2 System, but it can take any position of adjustment, where the receiver can easily decode the signal L1. Of the receiver to assess the alarm L1 in the header to define an additional parameter (in particular, the position of the label), as well as final frequency (Dependent) Static data slice.

Usually accommodation sending device and the receiving device, which is used in this second scenario, implementation, rather like the placement of the sending device and the receiving device, which is used in the first variant of implementation, that is, as a rule, are provided the same basic blocks that are shown in figure 6 and 7.

The transmitting device 400, which is used in the second variant of implementation therefore contains modulator 410, which modulates each of the many data streams for carriers frequencies of the corresponding frequency band in one group from one or more channels, each of the bands takes no more than the configured maximum bandwidth that is less than or equal to the channel bandwidth, generator 420 information about the band, which produces information about the band, and determining the frequency band corresponding to all the streams of data carried within one frequency channel, and the information about the band includes frequency display, shows the frequency, and the usage of frequency tuning, with the first value of the flag, indicating that the frequency specified mentioned indicator frequency settings, you can directly use by the receiving device to configure, or having a second a flag value indicates that more information about setting should be used by the receiving device to configure, and transmitter 430, which transmits mentioned data streams, modulated on carriers frequencies, one or more elements referred to information about the band in the relevant provisions of frequencies within each frequency channel and referred for more information on configuring.

Thus, the receiver is 500, which used in this second scenario, implementation, contains receiver 510, which smoothes the bandwidth of the receiver with a frequency channel to take, from the frequency of the channel, an item of information about the band, and with such information about the band determines the frequency band corresponding to all streams of data carried within this frequency channel, and information about the band includes frequency display, indicating the frequency and the usage of frequency tuning, with the first value of the flag, indicating that the frequency specified mentioned indicator frequency settings, you can use directly in the receiving device to configure, or having a second a flag value indicates that more information about setting should be used in the output device, and the device 520 read information about the band, which reads the information about the band, and retrieves the frequency bands given frequency band by the assessment referred to flag the use of the frequency settings and the corresponding indicator of frequency tuning, and which reads further signaling information, including additional information about configuring the case when the flag of the use of the frequency setting is used in the above-mentioned second meaning of the flag, where the above-mentioned receiver 510 configured to tune frequency settings, read the specified indicator frequency settings given frequency band in case the flag of the use of frequency setting is set on first mentioned the value of the flag or use the said additional information about how to configure settings in case the flag of the use of frequency setting is set on the second referred to the value of the flag.

The corresponding sequence of operations are shown in figure 14. Stages of 700 and 710 essentially identical stages, which are explained above with reference to fig.13. At the stage of 755 evaluate the usage of frequency tuning. If the flag is the use of the frequency setting is set to the first value flag (value is 00 in table 6), the receiver is a receiver that is already set to the correct frequency and can directly read (phase 720) data payload in the band, the tuned. If the flag is used frequency setting is set on the second a flag value (a value of 01 in table 6), for information about setting is used at the stage of 765 and then is used to reset the settings to the correct frequency setting the stage 770, after which the receiver reads (phase 720) data payload in a frequency band which is now re-tuned.

The present invention can be used predominantly in the system Vod (video on demand). In the system Vod usually difficult and expensive is scanning (impossible in some cases, as the flows are changing). Information NIT is not transferred within TS, but is signalled via a particular challenge, for example, call Internet (http://) (for example, through these IP distinct and different from the audio and video data; in practice it will probably run through the same physical cable, but, probably, even will be through another or wireless connection). This is the specific case when the alarm DSTF becomes the most sensitive in terms of saving time. For a normal case broadcasting the same information can be obtained by scanning the channel.
