I recently encountered a headache caused by the IsDB code stream issue. I have found a lot of relevant materials to learn.

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

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

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
