Trying to sync video of football game w/ Audio of radio broadcast

Anybody know of a unit to do this? I love listening to our local radio
announcers for the game while watching the video. However, the radio
broadcast is a good 4-5 seconds before the video.

So I want to delay a radio broadcast by 4-5 seconds. I would imagine I
would run the tape out to the delay unit, back into the tape in, and
listen in a monitor mode.

There are commercial units that run delay for radio stations. I can never
figure why radio stations don't use them to synch up their broadcasts with
football TV -- it could not be very hard. Listening to "psychic
play-by-play" with TV video is really irritating. Also, not hard to imagine
a small unit that would just send the digitized radio signal to a disk or
chip and then out again after a specified delay. Should be cheap but
apparently no one who could do that thinks there is a good market for it.
Also, not sure if you could integrate it with an existing system, such as a
home theater setup.

Yeah, I once looked for the same thing for the same purpose.
Came across this: http://delayplayradio.com/

$140 was more than I was willing to spend on something for an occasional
game though.

I'm willing to bet that you might be able to do the same thing with a
computer and a little creativity though. Thought about giving it a try with
my laptop (has audio in and out), but never got around to it...

Exactly what I want, thank you.

I've also posted this request in an electronics ng, so we'll see if
there's a relatively simple circuit that can do the same. I'm willing
to bet there is.

Well, one issue is that there would be a variety of different delays to
choose from depending on the Satellelite service, HDTV, Cable, or OTA.

Your welcome. Yeah, it doesn't seem like something that could be overly
complicated. Almost as if it could be done with a PCB, a few components
and IC's, and an hour with a solder gun. Post back if someone has any plans
to it! I'd like to build something like that myself. (Can't really justify
$140 for just a few games, but for like $40 or so it would be a fun
project.)

Thanks!

Eric, I found this:

This sample circuit is based on a chip called MX609P. This chip is a
CODEC for audio. The basic operation is Audio In, then there's a pin
that encodes the data serially. You then save it to some RAM. There's
a counter from the MX609P and once the count hits a certain value, the
data stored in RAM is output back to the MX609P, it's decoded back to
audio out.

Pretty simple, really, and it's just a matter of putting enough memory
to store the amount of audio you require. Probably could set up some A
to D input so the delay could be set with a pot. I may give this a
shot over the holiday...

My step-dad does this using his TiVo unit...he just pauses the TiVo for
a few seconds, and then starts the playback again while listening to the
radio. Within one or two attempts, he seems to get it the TiVo-delayed
picture synced up with the radio broadcast.

Since our TV broadcast is already behind the radio broadcast, I would
have to hook up the Tivo (if I had one) to the radio instead of the TV.

I don't think he does this.... ;-)
