Composite video uses 525 vertical lines with a 15.75KHz scanrate, *interlaced*. Any box that could convert your video to composite couldn't do it on the fly. It would have to contain a full color video memory, so the input and output could be almost totally asynchronous. It would also have to do some kind of filtering to compress 1024 lines of information into 525 (or 512). I'm sure it can be done, but for what kind of $$$? ------------------------------------------------------------------------------ Name: Robert Skinner Mail: Saber Technology, 2381 Bering Drive, San Jose, California 95131 AT&T: (408) 945-0518, or 945-9600 (mesg. only) UUCP: ...{decvax,ucbvax}!decwrl!saber!skinner ...{amd,ihnp4,ittvax}!saber!skinner
