I'm interested in this project and have some DV equipment that I could
contribute, but I have a big question about what the application is for
thi technology.
For videoconferencing, I believe you can get pretty much equivalent
results from MPEG2, although quite frankly, we are seeing users pleased
with much lower quality than that. Further, we are actively discouraging
the use of motion JPEG-like codecs for videoconferencing because they use
no temporal compression (I suppose DV is like mezzanine MPEG2, can someone
confirm that). Further, this doesn't really represent a
standards-development direction including call signalling, tracking, etc.
So that leaves video production. We do use some DV for video production,
but are focusing on SMPTE 259M and SMTPE 292M for that. DV isn't high
enough quality for many applications, being very compressed, and it
doesn't support HDTV. Even the news folks, which are the bottom of the
heap in my book, are using souped up DVCPro running at 50mb/s (100 mb/s
for a two-way conference).
So I guess I am curious about just how folks see this being used.
Obviously it's a big bitstream to stress the routers with, so I think
that's legit. Is someone envisioning an application or virtual network of
this? I might like to participate if so.
Hopefully,
-Tyler
