The problem I see with this is how much a person company would pay for this. It's this simple. The actual tuner is pretty simple and can be on some PC card and be set to the station with a micro-controller. But there is no escape from having a tuner per channel.
What may tank this endeavor is the price of such a custom system. Off the cuff I estimate it to be about 20 to 25 thousand USD for such a box. Walmart VCR's run under 50USD so that's only 4,000 USD.
Is it worth this?
We have a need to monitor 80 TV Cable stations. We will tune to individual stations and feed stereo audio output to an audio fingerprinting system. Instead of 80 VCR?s, we are looking for another type of TV/Cable tuning device ? preferably to save space, we?d like to have one box unit that can tune to and output multiple stations.
Any suggestion for an item that would fit this application would be appreciated.
