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.
