Hi, all,
I have not been following the development of this draft.
However, in the context of my involvement in another standards
organization which is addressing JPEG2000 motion images I have
been considering the resolution scalability of JPEG2000. In
particular, there is interest in separating the JPEG2000 code
stream into a "base layer" and one or more "enhancement layers".
This strategy is familiar and also seems beneficial in the RTP
multicast environment, where different recipients can subscribe
to different layers depending on their processing capabilities
and connection bandwidth. This could also be a tool for
congestion management.
Has there been any consideration given to allowing a JPEG2000
video stream to be divided across several RTP sessions (base
layer session, enhancement layer session) and reassembled at
the receiver? The structure of JPEG2000 seems to make this
relatively straightforward.
My apologies if this is was well-discussed and settled in the
past, while I was not paying attention.
Cheers,
Chuck Harrison
