[BC] DTV Audio Levels

[Clayborn, Kevin]

Group,

Been on the road all day, just now got back "on-line".

Seems Bob, Frank and Kirk have already addressed the issues brought up
today.

Nothing more for me to do except go find a nice frosty cold one.

Then Bob Orban wrote:
Our processors for digital channels, including digital TV, typically 
delay the audio by 25 ms and can be padded to one frame. The 25 ms of 
delay results from a cascade of the phase-linear crossover in the 
multiband compressor and low-IM look-ahead limiting. 

...lots snipped out...

The upcoming HD-SDI interface card for our 8585 surround processor 
includes video delay to ensure that the audio and video remain in 
sync when passed through the unit.
