Program-specific information (PSI) is metadata about a program (channel) and part of an MPEG transport stream. The PSI data as defined by ISO/IEC 13818-1 (MPEG-2 Part 1: Systems) includes four tables: The MPEG-2 specification does not specify the format of the CAT and NIT. PSI is carried in the form of a table structure.

2006年10月9日 · Document A/78, “ATSC Recommended Practice: Transport Stream Verification,” outlines a common methodology for describing transport stream conformance criteria. This document explicitly describes the elements and parameters of ATSC Standards A/53 and A/65 that should be verified in a transport stream for it to be considered a compliant emission.

PMT (Program Map Table): one per “program ”; identifies elementary streams in “program ” and gives their types (audio, video, etc.) and PIDs. Supports tuning by physical channel number and MPEG-2 program number.
