    We had wondered why not something like Twitch as a multicast-er. Clearly getting the streams to a service like this could have some issues, both technical and meat-space interference.
    If a chicken and a half, can lay an egg and a half, in a day and a half... how long would it take a monkey, with a wooden leg, to kick the seeds out of a dill pickle?

      Sure, that would work, although you might have to contend for bandwidth. A broadcast or multicast system is more efficient and seems more elegant. We should strive for using technology to its best and fullest potential. (Consider DEFCON Secure WiFi... Sure, DEFCON could offer the same insecure WiFi experience that we're all used to, but if we can do better, we should.) Plus there is the novelty factor. It is now possible to transmit multiple HD streams over the air on a tiny budget. An OTA broadcast would demonstrate capabilities that we could only dream of a few years ago. That being said, there are a lot of practical hurdles to doing DCTV over the air, and falling back to technically inferior but tried-and-true technologies seems like the way to go, at least for now. (Anyone remember M-Bone?)

        I'm not sure about the video, but the audio clipping could be due to the mismatch between "pro" line level (+4 dBu) and "consumer" line level (-10 dBV). Hopefully the DCTV capture hardware can accept "pro" line levels. A simple software audio compressor/processor (like the free stereotool) could help a lot.

        I've said this before, but I'd really like to get the live caption data streamed out somehow. I think it'd be kind of awesome to idle in an IRC channel for each track and see what's going on everywhere simultaneously.
