Watch. Fglrx. RFIDAnalysis.org. Video for Linux (v4l) resources. This page was born in 1997 and was updated faithfully for a while, but has been stale for far too long.
You should head over to the V4L-DVB wiki for current info. Anything shown below is what's left of the original links which are still working, although many of them are also very old and not very useful. Last update pass (dropping dead links and updating those which have moved): May 2013 Drivers. Redefining the Media.
