Subject: [video4linux] Broadway Mpeg Capture and Composite Out Board

The Data Translation Broadway board is a device that can do high quality
capture from composite and s-video at a good frame rate. It can also do mpeg
video compression in real time. The image quality is amazing for mpeg-1.
There's hardly any artifacts at all. The card also includes a composite NTSC
output.
If anyone's interested, have a look at the larger sample clips on
http://www.b-way.com/. Data Translation also makes a bunch of other neato
imaging boards, including a capture card with 4 bt8xx's on it. Their main
web site is at http://www.datx.com/
They've released the source code for their Windows 95/98/NT driver, and I
was hoping someone might be interested in working on a port. My kernel
hacking skills are pretty limited, however I do have contacts at Data
Translation, and might be able to secure boards or additional technical
information for skilled developers seriously interested in working on the
project.

I'd be interested in writing a driver for the mpeg card and/or the quad
bt8x8, if the hardware and docs can be obtained. Previous and current
projects include a number of video devices including the bt848 driver
rewrite for V4L2. It's stalled right now because there are other things
more pressing at work, but it'd get a lot more timeslice if need-be.
'References' can be found on my v4l2 page, listed in my .signature.
Something that might influence the process is the fact that my workplace,
Oregon Graduate Institute, is doing major research into streaming video
quality of service, including a markup for MPEG that allows intelligent
dropping of data to deal with lower bandwidth links. All our data sources
are currently pre-recorded using either really old Parallax hardware or
the new Canopus DV card we purchased. One of these things, capable of
doing live MPEG encoding, would be amazingly useful in our research.
TTYL,
