If there had been created a universal transport stream format that interleaved
the video and audio together on a frame by frame or at least group by group
basis, along with timing tags for each such chunk, then we would not be having
such sync problems.
A local broadcaster had frequency A/V sync issues with programs fed over the
Pathfire satellite service. I looked into one of these machines and noticed
that the entire video and entire audio were fed separately. If the satellite
signal had a glitch that caused some loss of content, the timing could then
be off by however much content could not be recovered.
