Hi Jim, Since this is both video and course-work related, have a look at the LoonBoard: http://www.newae.com/prod.html http://www.newae.com/loonboard/loonboard.html Collin wrote a couple of articles about it in Circuit Cellar (see http://www.newae.com/arts.html), and the development process is open-source, and will give folks some exposure to the BT.656 standard. See also the docs for the video decoder and encoder chips used: http://focus.ti.com/docs/prod/folders/print/tvp5150a.html http://www.analog.com/en/prod/0%2C2877%2CADV7173%2C00.html Hope this helps! Andrew.
