I recently encountered a headache caused by the IsDB code stream issue. I have found a lot of relevant materials to learn. The following is an excerpt from the Internet: It should be said that after truly understanding TS and reading the book "digital TV business information and coding" recommended by friends, MPEG2 TS and digital TV are closely inseparable, it is worth summarizing some of these relationsh

Prior to the establishment of Isma, the active image expert group defined the reuse of one or more audio, video, and data element streams when developing MPEG-2 system standards Method, MEPG-2 standards were officially released in November 1994. The data stream is packaged with a time mark to form a encapsulated element stream (PES ). Audio , Video and data (optional) PES are reused together to form a single output stream that can store and transmit applications. MPEG-2 system standards are desi

The PES package consists of Baotou and payload , and the specific format is summarized as follows:You can see that Pts/dts is in the PES package , these two parameters is the key to solve the video-audio synchronization display, to prevent the decoder input cache overflow or underflow.PTS indicatesDisplay Unitappear inSystem Target Decoder(Std:system target decoder), DTS represents the timeAccess UnitAll bytestime to remove f

Statement 1: Although Isma and MPEG-2 ts over IP can be used for IPTV stream transmission, but due to the Mechanism and the original intention of different standards, there are some differences in IPTV service support, the specific analysis is as follows: 1. Support for business functions Isma currently supports MPEG-4 and H.264 and does not support other encoding standards. As video and audio streams are transmitted separately, Isma provides more fle

Live broadcasting: The existing Isma method. The process is as follows: Video collection-> video encoding-> RTP packaging-> UDP multicast; Audio collection-> Audio Encoding-> RTP packaging-> UDP multicast; The above is the workflow of mp4live. Live Video: mpeg ts stream mode. The process is as follows: Video collection --> video encoding --> Audio collection> Audio Encoding> TS packaging> RTP packaging> UDP

In MPEG-II standards, in order to combine one or more audio, video, or other basic data streams into one or more data streams for storage and transfer, it must be re-packaged and encoded. In the code stream, it also needs to insert various time tags, system control and other information, and finally sent to the channel encoding and modulation. In this way, two types of data streams, TS and PS, can be formed, which are suitable for different applicatio

Stream (program stream) PS Flow consists of PS package, and a PS package is made up of several PES packages (here, ES through the two-layer package). The packet header of the PS package contains synchronization information and clock recovery information. A PS package can contain up to 16 video PES packages and 32 audio PES packages with the same 1: benchmark. Ts: The Ts--transport stream (the transport Str

TS is all called mpeg2-ts, the abbreviation for "Transport Stream". The mpeg2-ts format is characterized by the requirement to decode independently from any segment of the video stream.

**************************************** **************************************** ********************I. Ts Encapsulation1. IntroductionMPEG2 transport stream (TS Stream) is a data stream defined according to the ITU-T Rec. h.222.0 | ISO/IEC 13818-1 protocol.To transfer and store the encoding data of one or more programs in an environment where serious errors may occur.

(1) Es-elementary Streams (Original stream), the encoding of video, audio signals and other data is compressed into the data stream called the original stream. The original stream includes the access unit, such as the video source stream's access unit is a pair of image encoding data. (2) Pes-packetized Elementary Streams (the original stream of the group), the grouping of the original stream is called the PES grouping, is a data structure used to transmit the original flow (3) The program is a
