Audio dropout with mpeg 2 encoding on Cable outlet
on Feb 1, 2012 at 1:43:31 pm

One of the outlets I send commerceial content to is a local cable company which serves subscribers only within city limits. They have their own set of encoding specs, etc, and have always had periodic audio problems of sorts, but it seems my spots in particular suffer dropouts more often. They mostly load other source material from Beta sp, mine from Mpeg 2 files off an FTP. I have discovered that these dropouts occur when there is something more data intensive, (motion grpahics, etc., maybe a fancy transition) onscreen. Visuals are fine, just the audio breaks up or drops out for a few frames. Is this a buffering issue, bit rate, or streaming problem? and something I can avoid by tweaking the audio encoding? Any help much appreciated.
