John,
With regard to screen space logistics, we've developed a version of
vic that does DV and HDV - full details and perhaps a demo at the
forthcoming AG Retreat. One of the changes is the ability to resize
the video window(s) to any size you like. Thus you could accomodate
several streams at smaller than true HD size when display space
becomes tight.
BTW, I think that when DV, HDV, HD are all more common in the AG,
best practice will be to always send those formats as duplicates of
standard H261 streams so that other sites can choose to view their
own preferred mix of H261 and higher resolution formats (somewhat
avoiding the screen real estate problem you raised, not to mention
bandwidth issues). The cameras we've been testing with have a number
of simultaneous outputs available so its trivial to send both DV/HDV
and H261 at the same time.
