SMPTE 32NF Networking Technology Committee
The VSF is providing resources to move several projects through the
Society of Motion Picture and Television Engineers (SMPTE). Our work
is being conducted under the 32NF Networking Technology
Committee. There are two ad-hoc groups, both chaired by Brad Gilmer,
Executive Director of the VSF. The first group is the VBR
group. The second is the Video over
IP group.
The 32NF Technology Committee is currently conducting a two-week
review of a working draft of SMPTE 2022-4, VBR non-piecewise constant
MPEG-2 Transport Streams over IP networks. Once any input from this
review is received and reconciled, we intend to move this document to
Committee Draft status and begin a formal due-process ballot as part
of moving the document through to adoption and publication.
At the last SMPTE meeting, the 32NF committee agreed to adopt a
work statement which covers transport of JPEG 2000 on IP
networks. It is likely that this work will be assigned to the Video
over IP Ad Hoc Group at the next SMPTE meeting in September. We now
have a first draft of a JPEG 2000 on IP document which has been
presented to the VSF HBRAV group.
Finally, we have made good progress on mapping High Bit Rate Media
Transport (formerly High Bit Rate Audio/Video) onto IP networks, and
we have resolved all outstanding comments. We still have quite a bit
of work to do on the HBRMT FEC document, but the committee is making
good progress on these issues. I anticipate that we will be in a
position to introduce these two documents to the SMPTE in
September. These two documents standardize the carriage of
uncompressed A / V at rates up to 3 GB/sec, and also support MXF
encapsulation of media.
Please contact Brad Gilmer if you would like to
participate in any of these activities.
