Transport stream (TS) is specified in MPEG-2, and it is a standard format for transmission and storage of audio, video, and data, and is used in broadcast systems such as DVB and ATSC. Transport stream specifies a container format encapsulating packetized streams, with error correction and stream synchronization features for maintaining transmission integrity when the signal is degraded.
The connection of Transport Stream to Program Stream is as follows. Firstly, PS is designed for reasonably reliable media, such as disks (like DVDs), while TS is designed for less reliable transmission, namely broadcast. Further, Transport Stream transmissions may carry multiple Program Streams.
Some Important elements of a transport stream:
Packet - A packet is the basic unit of data in a transport stream.
PID - Each table or elementary stream in a transport stream is identified by a 13-bit packet ID (PID).
Programs - Transport stream has a concept of programs. Each program is described by a Program Map Table (PMT) which has a unique PID, and the elementary streams associated with that program have PIDs listed PMT.
Program Specific Information(PSI) - There are 4 PSI tables: Program Association , Program Map, Conditional Access, and Network Information. The MPEG-2 specification does not specify the format of the CAT and NIT.
PAT - stands for Program Association Table. It lists all programs available in the transport stream.
PMT - Program Map Tables (PMTs) contain information about programs. For each program, there is one PMT.
PCR - To enable a decoder to present synchronized content, like audio tracks matching the associated video, at least once each 100 ms, or PCR is transmitted in the adaptation field of an MPEG-2 transport stream packet.
