As many of you know, ATSC A/53C has dictated that all PID assignments (except for PAT) will be numbered equal to or above 0x0030 after January 1st, 2005. At the same time, the "program paradigm" for PID assignment has been deleted. The "program paradigm" is in older versions of A/53, and assigns PID numbers with these formulas (where N equals the MPEG-2 Program Number). PMT = 16*N PCR = 16*N + 1 Video = 16*N + 1 Audio = 16*N + 4 One of the local DTV stations here in the SF Bay Area, KGO-DT, has fulfilled the equal to or above 0x0030 PID requirement by changing their Program Numbers from 1 and 2 to 3 and 4 and continuing to use the old "program paradigm". This results in PIDs 0x0030, 0x0031, 0x0034, 0x0040, 0x0041 and 0x0044. This has caused some receivers to display a black screen and no audio when tuned to KGO-DT. No amount of re-scanning will resurrect these receivers. So the question to the group is: What is the safest way to satisfy the equal to or above 0x0030 requirement? Since the "program paradigm" has been deleted, should MPEG-2 Program Numbers now start at 1 (instead of the previously recommended 2)? Thoughts and experience would be appreciated.
