Question:

What is a PAT (program association table) in MPEG?

Answer:

A PAT is data appearing in packets having PID code of zero that the MPEG decoder uses to determine which programs exist in a transport stream. PAT points to PMT (program map table), which, in turn, points to the video, audio, and data content of each program.
