HD Capture Cards
Other HD capture cards available and possibly useful:
- DVS
- AJA
- BlackMagic Design
- Optibase
- VideoPump (can't find that but it seems to be related to MediaPump) - but it was used by ResearchChannel for prototyping HD over IP
- bluefish444
However, these cards are usually intended for editing and thus not optimized for latency. Mike Wellings reported interesting results about card latencies. Other cards possibly supported in Linux are listed at http://www.lmahd.com/cinelerra.html.
