DTV: Internet TV

"Internet TV is Open and Independent
DTV is a new, free and open-source platform for internet television and video. An intuitive interface lets users subscribe to channels, watch video, and build a video library. Our publishing software lets you broadcast full-screen video to thousands of people at virtually no cost. The project is non-profit, free and open source, and built on open standards. A Windows version of DTV and a full website are well underway and will arrive in the next several weeks.
The Channel Guide is Open
Today, along with the Mac Beta, we're launching the built-in DTV Channel Guide. Publishers of DTV-compatible channels can now submit channels to be included in the guide. If you have an RSS feed with video enclosures, your channel is already compatible (see our ideal RSS format). This beta version of DTV embeds QuickTime 7, so any video that plays in QuickTime will play in DTV. DTV suppports standard HTTP downloads as well as BitTorrent downloads. Submit your channel today!"
