![]() ![]() A Program Map Table describes every single program (PMT), which has a unique PID, Program Specific Information(PSI) - There are 4 PSI tables: Program Association (PAT), Program Map (PMT), Conditional Access (CAT), and Network Information (NIT), PAT - PAT stands for Program Association Table. Various elements make up a transport stream - namely Packet - A packet is a 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. 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. In addition, the transport stream (TS) can handle error correction and stream synchronization issues much better than other formats when the signal gets degraded. ![]() ts file format is used to broadcast high-definition TV (HDTV) - it is specifically designed for less reliable transmission, and broadcast fits well. It describes a combination of lossy video and lossy audio data compression methods, which permit storage and transmission of movies using currently available storage media and transmission bandwidth. ![]() MPEG-2 (aka H.222/H.262 as defined by the ITU) is a standard for the generic coding of moving pictures and ISO/IEC 13818 MPEG-2 at the ISO Store.
