J2K Technical Recommendation Group
The VSF J2K Activity Group completed the first phase of its work during the 1Q 2013, and issued a Technical Recommendation on 4/15/2013 entitled "Transport of JPEG 2000 Broadcast Profile video in MPEG-2 TS over IP" (pdf, 308k). The Technical Recommendation, which uses existing standards to define interoperable profiles for real time streaming of a broadcast profile JPEG 2000 codestream wrapped in MPEG2TS, with audio and ancillary data and encapsulated in IP with FEC, is available to VSF Members and Non-Members in PDF format.
After publication of TR-01, the J2K Activity Group organized several private J2K interop events in 2013 and 2014 hosted by Fox Networks in The Woodlands, Texas. The culmination of this initial interop work was a major public interoperability demonstration of HD 720p encoded JPEG 2000 (J2K) video at VidTrans 2014. This Interop featured ten equipment manufacturers and technology suppliers, making it the largest technology demonstration ever held for JPEG 2000 video over IP technology. Subsequent private interop workshops were organized in 2014 and 2015 in cooperation with the VSF Interop Activity Group, followed by another public demonstration at VidTrans 2015 focusing on HD 1080i interlaced video, audio and ancillary data transport.

Current work in the J2K Activity Group considers bidirectional, interactive applications that require specific optimizations for low system latency, as well as real-time transport of high end film and television production video formats. Another future goal may be to define interoperable profiles for real time streaming of JPEG2000 video wrapped in MXF with audio and ancillary data, and encapsulated in IP.
The J2K Activity Group is liaising with DVB & EBU in order to create recommendations that is aligned with ongoing work on J2K over MPEG2TS within these groups.
