[BC] DTV Audio Levels

[RichardBJohnson at comcast.net]

If I am a network TV station licensee and I get a digital network feed, can't I control all aspects of that network signal? As the licensee, I am required to have absolute control. If the signal doesn't meet specs, it's my license, not the network. If somebody swears, it's my fine, not the network, etc. If the TV station has complete control of the content as required by law, then it should be trivial to maintain audio levels within acceptable limits. Now, if the network saw fit to multiplex the audio onto the video instead of sending it by land-line (seems reasonable), then the broadcaster has no choice but to demultiplex that audio, feed it into something that can control it, and then multiplex it back. I think the broadcaster needs to have the same control over video as well. The broadcaster needs to fade to black at the very least in order to have control over what is being broadcast. Imagine somebody sending the wrong video feed to an uplink. Mrs. Robinson's porno flick isn't acceptable according to the FCC. The broadcaster needs to have control and the control can't come from some network master control in New York. It needs to be local to the TV station.

Cheers,

Why is that? The concept is easy to imagine. Does my TV experience 
make me more smarter than most everyone else here? It's a nice 
fantasy, but that's all.

Understanding the combobulation and discombobulation of digital 
signals isn't really the problem. What's hard to fathom is why the 
FCC would approve a system that virtually guarantees ongoing 
violations of their regulations. Unless, of course, the industry's 
designers of the implementation of the system didn't understand it 
and used the analog model which assumes levels should be tolerable 
and easy to manipulate.
