"The 3 Gbps over a single cable standard is SMPTE 424M." -Ron Interesting, I missed that. Dang it all if the university won't let me buy the SMPTE standards (or any standards or books for that matter) so that I could find out about these things. They think all information is available on the internet. They'll spend $Millions on equipment and $0 on consultants, development and research materials, support services and equipment, etc. They expect me to know everything (and immediately, too.) Yeah, I know, I hear the violins playing, too. Does anyone know if any equipment in the near future will have SMPTE 424M I/O? Is there a street name for it like HD-SDI seems to be synonymous for SMPTE 292M? Dan Grimes
