13.3 What is an MPEG Transport Stream?
MPEG Transport Stream (MPEG-TS) is a standard format for transmission and storage of
audio, video and Program and System Information Protocol (PSIP) data. It is used in
Broadcast systems such as DVB.
Transport stream specifies a container format encapsulating packetized elementary
streams, with error correction and stream synchronization features for maintaining
transmission integrity when the signal is degraded.
A Transport Stream may carry multiple programs.
13.4 What is a PID?
Each table or elementary stream in a transport stream is identified by a 13-bit packet ID
(PID). A demultiplexer extracts elementary streams from the transport stream in part by
looking for packets identified by the same PID. In most applications, Time-division
multiplexing will be used to decide how often a particular PID appears in the transport
stream.
