[BC] DTV Audio Levels

[RichardBJohnson at comcast.net]

I don't want to belabor the point, but must post production I've seen uses time-codes for alignment. All the HDTV production stuff has time-codes so I'm told. I suppose if somebody is trying to use some home studio stuff for professional production, there might be a problem, but I recently was on the "talent" side of a HDTV setup for a British production company and they had a time-code generator going to every piece of equipment so it could be put together post-production.
Cheers,

That's all well and good in theory Richard.  In practice, the TV guys tell me a different story.  Lip sync is a real problem for them with digital TV.  A few milliseconds becomes VERY obvious VERY quickly, especially when the audio leads the video, which can easily happen when doing post production where the audio and video paths are separate and have different processing delays.  It can quickly become a real mess.
