Audio Sync with HD

[mpdillon]

Hi,
I live in the Philadelphia area. I like to watch the Igles games in simulcast with a local radio station. However, with Comcast Digital signal the simulcasted audio from the radio station arrives about 3 to 5 seconds before the Comcast Digital video. Basicly, you kno how the play ends before you see it. Does anyone make a receiver which has a programable audio delay?\
thanks,
pat

New receiver

Most receivers made in the last couple years will have the delay feature. They usually call it audio delay or lip sync delay.
However, I think that most receivers will allow delays in the 100-200 milliseconds range and you are describing audio being 3-5 seconds ahead. Sounds like it might be a comcast issue.

The Felston DD540 can delay up to 680 ms, but even that is far short of several seconds. It appears that the TV or radio source (the later one) is intentionally delaying their signal, perhaps for the purpose of muting objectionable content, or to more easily switch in commercials and such.

Good luck trying to find something to create that much delay.

Of course, this could be created by a computer program, using a disk for buffer space.

I have the exact same problem in the DC area. It's not limited to Comcast though, as even over the air HD signals seem delayed a few seconds behind real time. It makes it impossible to listen to radio play by play while watching the game in HD, but switching to the regular def broadcast solves the problem. I've even thought about using a guitar delay pedal on the FM radio signal to synce it up, but there doesn't seem to be a way to introduce it into the reciever's signal chain since it's not a separate tuner. I wish these HD broadcasters would get their game together broadcast in real time with accurately lip synced audio!

New Yamaha

One of the features on the new Yamaha RX-V2700 is a time base corrector on the video scaling chip. Not sure if this would solve your problem.
