Chris, is this true of all HDV cameras? I thought it was higher. Is it true for the Sony HC-7 that sells for about $1400? I was trying one out but got different latencies--probably depends on the application involved. I was using it with ExtendedVideoService module that Sang Woo Han/GIST is working on for the WindowsXP platforn. > We have recently developed a new version of vic with DV and HDV > capture & display capability.

I am installing some public "portals" on campus that will be always on, persistent video/audio for "one on one" ad hoc communication and want to use the best quality video I can. I may have to start with DVTS but pending funding I'd like to move to HDV and eventually to uncompressed HD.
