detailed description

Embodiments of the present invention are described below through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation modes, and various modifications or changes can be made to the details in this specification based on different viewpoints and applications without departing from the spirit of the present invention.

It should be noted that the diagrams provided in this embodiment are only schematically illustrating the basic idea of the present invention, and only the components related to the present invention are shown in the diagrams rather than the number, shape and shape of the components in actual implementation. Dimensional drawing, the type, quantity and proportion of each component can be changed arbitrarily during actual implementation, and the component layout type may also be more complicated.

The invention provides a TS stream transmission method. The TS stream transmission method can be applied in a wireless broadcasting system. In one embodiment, as shown in Figure 1, the TS stream transmission method includes:

Step S1, separating the TS multiplexing stream including N channels of services into corresponding N channels of service data streams and one common data stream, where N>=2. In one embodiment, as shown in FIG. 2, the TS multiplexing stream is a Big TS composed of N SPTS (Single-program transport stream, single-program transport stream) (N>=2), that is, the TS multiplexing stream . Each SPTS consists of a piece of program information, including video stream, audio stream, program specific information stream (PSI) and other data packets. The information transmitted by the TS stream (SPTS or Big TS) includes the following types: (1) PES packets of video and audio and auxiliary data; (2) Program Specific Information Table (PSI), including four types of tables, description sheet Program Mapping Table (PMT) for channel program information, Program Association Table (PAT) for describing multiplex information of multiple programs, Network Information Table (NIT) for describing network system information, and conditional access table (CAT) required for CA system ); (3) Various service information tables (SI), including service description table (SDT), segment information table (EIT), time and date table (TDT), and optional business group table (BAT), running status table (RST) and Time Offset Table (TOT), etc. For the business data encapsulated in the transport stream, it can be separated and merged according to the different data contents. The separation operation of TS multiplex stream mainly includes 2 types or their combination: 1) Separate different service components of the same transport stream (TS multiplex stream) into multiple partial transport streams (TSPS, service data stream), respectively 2) Extract the time-synchronized and repetitive parts of two or more transport streams and merge them into a common data part transport stream TSPSC (common data stream), and use the common transport channel (CTCH) bearer; empty packets are filled in the repeated content positions in each original transport stream to form a partial transport stream.

As shown in Figure 3, the basic unit of the TS stream is the TS packet, whose length is fixed at 188 bytes. The TS packet starts with the synchronization byte 0x47, and the packet ID (PID) is used to determine the type of data in the TS packet. (Video, Audio, Data or Program Specific Information). The process of locating the synchronization flag of the TS stream is shown in Figure 4, which specifically includes: opening the TS stream input port, reading one byte from the input transport stream in sequence until the 0x47 flag is obtained, and after recording the position of the flag, continue to search After the 188th byte after the address, judge whether it is still 0x47. If it is 0x47, confirm that the synchronization byte of the first TS packet is found; if it is not 0x47, repeat the above synchronization byte addressing process. After the synchronization subsection of the TS packet is located, the complete TS packet can be obtained. Analyze the TS packet header information, extract the PID identifier from the packet header, and combine Table 1 to know the PSI/SI form type carried by the TS packet. Since the TS packet length is fixed at 188 bytes, and also for the reliability of information transmission, each PSI/SI form information cannot be stored in one or continuous TS packets. In order to obtain complete PSI information, it is necessary to splice the PSI/SI form sections in multiple TS packets (different sections of the same table are indicated by the Section number indicator bit in the header to indicate the connection order of the sections) to construct a complete PSI/SI form SI form. The PID value definition of the PSI/SI allocation table is shown in the following table:

surface PID value PAT 0x0000

CAT 0x0001 TSDT 0x0002 reserve 0x0003～0x000F NIT,ST 0x0010 SDT,BAT,ST 0x0011 EIT,ST,CIT 0x0012 RST,ST 0x0013 TDT,TOT,ST 0x0014 network synchronization 0x0015 RNT 0x0016 reserve 0x0017~0x001B in-band signaling 0x001C Measurement 0x001D DIT 0x001E SIT 0x001F

There is a strict index relationship between the PSI/SI tables, so the obtained PSI/SI table PIDs must be combined with their mutual index relations to obtain a complete PSI/SI table. The relationship between various tables of PSI/SI is shown in Figure 5. By reading and analyzing TS packets, all PSI/SI information tables can be obtained from the TS stream. These tables combine data and control information of all service streams, and the PAT table contains PMT table indexes of all program streams. According to The PAT can find the PMT table corresponding to each program stream; the PMT table includes indexes of all program stream information (such as PIDs of audio, video, data, subtitle and other data packets). The content in the TS stream is divided into two categories according to the mapping requirements: one is data information, which will be mapped to the data transmission channel (Data Transmission Channel, abbreviated as DTCH) in units of program streams (or program stream combinations), and the other is The common information of the program stream (Common Data, abbreviated as CDatax), this kind of public information includes three parts: the common information of N original TS streams, SDT other, EIT other, which will be mapped to the Common Transmission Channel (Common Transmission Channel, abbreviated as CTCH).

In one embodiment, the specific realization of separating the TS multiplexing stream including N channels of services into corresponding N channels of service data streams and one common data stream includes: copying the TS multiplexed stream into N+1 TSs Multiplexing streams, where N TS multiplexing streams only retain the service data contained in one service to obtain corresponding N service data streams, and one TS multiplexing stream only retains public information to obtain public data streams. Specifically, the separation of the TS multiplexing stream is carried out in three steps:

1. Copy the TS multiplexed stream into N+1 identical TS multiplexed streams. It is assumed that the structure of the TS multiplexed stream is as shown in the following table:

After copying, N+1 identical TS multiplexed streams are obtained:

2. Select N channels as TSPS, and separate information. The formation of N channels of TSPS is shown in the table below.

Wherein, TSPS represents a service data stream, and TSPS1, TSPS2, ..., TSPSN represent N service data streams. In one embodiment, according to the service-id and the corresponding data PID, the N service data streams in the TS multiplexing stream only retain the data information of a single program to form a Transport Stream Partial Stream (Transport Stream Partial Stream, abbreviated as TSPS).

3. The other TS multiplex stream only retains the common information of the N program streams, that is, the Common data in the table, to form a common part transport stream (Transport Stream Partial Stream Common, abbreviated as TSPSC), that is, to obtain a common data stream. The net data volume of the separated TSPS/TSPSC is equal to the data volume of the original TS multiplexed stream, and the TSPS/TSPSC is equal in length, code rate and time-synchronized with the original TS multiplexed stream. In one embodiment, the public information includes: 1, common information of N TS streams, which mainly refers to PSI information in the DVB-T2 system; 2, SDT other; 3, EIT other. Although SDTother and EIT other are part of the content of SI, because the content carried by them does not belong to the content of the local TS, they are regarded as part of the public information, and the corresponding SDT actual and EIT actual must be mapped to Data PLP. Among them, the storage information of the SDT and EIT tables is shown in the following table:

According to the content in the table, it can be known that SDT other with PID=0X0011Table-id=0X46 and EIT other with PID=0X0012Table-id=0X4F and 0X60-0X6F should appear in TSPSC.

Step S2, sending the N service data streams and one public data stream respectively through different transmission channels. In one embodiment, as shown in FIG. 6, the previously obtained N-way TSPS (N-way service data stream) and 1-way TSPSC (one-way public data stream) are applied to n+1 TCH (transport channel) to transmit information , including n DTCHs (data transmission channel) and 1 CTCH (common transmission channel), TSPS is mapped to DTCH, and TSPSC is mapped to CTCH. DTCH and 1CTCH have the same TCH_GROUP_ID (TCH_GROUP_ID is mainly used to establish the association between CTCH and DTCH, and CTCH and DTCH mapped from one TS stream have the same TCH_GROUP_ID).

In an embodiment, a preset modulation and coding method is selected for any one of the N service data streams before being processed and transmitted. Users can decompose TS to different channels for transmission according to their own needs, and can choose different modulation and coding methods for different services to enhance the flexibility of transmission and improve transmission efficiency.

In one embodiment, the TS stream transmission method further includes: multiplexing N single-program TS streams into one TS multiplexed stream including N channels of services.

In one embodiment, the TS stream transmission method further includes: receiving the N service data streams and the common data stream, and recovering the TS multiplex stream including the N service streams. In one embodiment, the TS stream transmission method further includes: demultiplexing the received TS multiplexed streams including N channels of service data streams into N channels of single-program TS streams. In one embodiment, the receiving end needs to find all TCHs in the group according to the TCH_GROUP_ID and reconstruct the original TS stream. Since TSPS and TSPSC are separated by adopting the method of replacing empty packets, when restoring public information, it is only necessary to replace empty packets with original data at the corresponding time point of TSPS. In particular, in order to accurately find the replacement position of the empty packet, N TSPS and 1 TSPSC need to be aligned in a strict sense, so it is necessary to analyze what kind of data is stored in the TS packet according to the PID in the packet header when restoring information, and then use the PCR clock to determine the exact position of empty packet replacement. The TS stream transmission method may further include: processing one of the received N service data streams and the common data stream to obtain a single-program TS stream corresponding to the one service data stream. In one embodiment, the recovery of SDT other needs special processing: because SDT other contains program information of other frequency points than this frequency point, it is necessary to keep the SDT other of other Services and delete the program information of this Service when restoring. SDT other. For example, the recovery of SDT content in TS3 is shown in the following table:

In one embodiment, the recovery of EIT other also needs special treatment: the EIT tables with Table_id 0x4E and 0x4F describe the current (present) and subsequent (following) events in the corresponding service, and the EIT table with table_id=0x4E must be sent. At this time, the EIT sub-table uses the first section to describe the event currently being played, and uses the second section to describe the event to be played. There is only one table loop structure in the first and second sections. The EIT tables whose table_ids are 0x50~0x5F and 0x60~0x6F describe the (schedule) events in the corresponding service within a certain period of time according to the order of the start time, and the table loop structure of the section is generally multiple. The contents of the EIT in TS3 are restored as shown in the table below:
