Record and playback high definition TV signals
Authored by: vansie on Apr 28, '04 07:11:26PM
I've had a DCT 6200 box from Comcast for about 2 months now and have been able to make recordings off it over its firewire connection since I got it. The only thing you have to check for is that the firmware of the box is at least 7.07 and preferably at 7.10. Once that's set, you can record HD (1080i, 720p, 480p) or SD (regular 480i) content alike to any Mac with a firewire connection and the VirtualDHVS software from Apple. You'll also need the AVCBrowser tool that comes with the FW SDK to properly setup the 6200 to record, it involves prepping the proper channel number on the FW bus for VDHVS. You can find all the info and discussion on this thread I started at AVSForum, as well as this more Mac-centric one.

On another note, playback with VLC of 720p or 1080i content is going to need a *hefty* CPU and probably won't play on anything but the latest and greatest G5's. With bitrates anywhere between 11 and 19 mbit, there's a lot of number crunching to be done. If you are lucky enough to have an STB or HDTV with firewire input I would strongly suggest you use that since those devices have built in mpeg2 decoders and they will have no issues playing your recordings back.
The encryption scheme agreed on by all parties involved is called 4C, and is similar in limitations to the HDCP scheme used on DVI connections on cable boxes, DVD players and displays.
