I sat in on the W6CX weekly next a little over a week ago and asked a few questions about their digital ATV setup. Its an impressive combination of analog and digital inputs that run through their repeater, to FM digital outputs. And even better, they are working on internet linking to their repeaters much the same way I was pondering. I'm not sure how far along that process is. It seems the repeater we'd have here would need an analog and digital component on the receive end, similar to how W6CX does it. But to internet link it, they were planning to use a Grandview box to encode the stream. Beyond that, I'm a little sparse on the details but it seems that's at least a good hint. I've seen different encoder/decoder devices online. Not sure exactly what this one does vs that one, but if I have it right, I think it would be something like: Camera streams into the encoder box Code streams across the internet to the repeater Repeater has a decoder on it and can pickup that stream If this was done right, I'd think that someone running just a camera to an encoder could send it over the internet, same as if they had an ATV transmitter. Question I can't seem to answer is: What is the bandwidth requirement for streaming TV/video -- in terms of the internet connection? Is it possible to use a lower bandwidth stream on a system that normally uses a higher bandwidth? (compress/de-compress?) Imagine if you could open a program/application, and using a webcam (adjusted to the right streaming bandwidth, bitrate, etc.) that you could connect to repeater X, just as if you had fired up an ATV unit and pointed a beam at it. And the recipients could reply back on RF, or even back on the same program. That's what I'd like to see. Something like Skype for amateur television, but more like Echolink.
