Home Stereo of the Future?
iCube has a device called Play@TV that serves video and audio from your computer to your TV, either wirelessly or via Ethernet. It has component, S-video and composite video ouputs and analog and optical digital audio outputs, but I don’t know whether it would be able to serve up HDTV. I would guess that it could if your computer is fast enough (it uses Windows Media Player to compress video on-the-fly to fit down your network pipe), but I’m not sure. Quick price check has it at $170 with wireless card and $150 without at ZipZoomFly.
