NettetA continuity-count error occurs when successive counter words contain the same count (indicating a repeated packet) more than twice, or the count is out of order, or packets are lost. To test for PMT errors, recall that the program map table carries the PID values of the packets containing the actual audio, video and data for a particular program.
