Hi Mayumi: please see the incoming liaison statement. From the IETF's AVTCORE working group. Hi IETF folks: please note that Shinji Watanabe is not responsible for MPEG anymore. The current contact point for ISO/IEC JTC1/SC29 and its subgroups (including WG1 JPEG and the various WGs and AGs that, in combination, make up MPEG) is Ms. Mayumi Koike, to whom this email is addressed. Stephan (IETF liaison to SC29).

The following aspects could be of interest for IETF AVTCORE working group: - The green metadata for "interactive signalling for remote decoder power reduction" is of interest for return channel signalling such as via RTCP. - It remains to be seen whether metadata signaling from the sender to the receiver could be included in IETF specifications, in particular when the content of the metadata is codec-independent (e.g., "quality recovery after low power encoding"). The AVTCORE Working Group is contributions driven and further work in the group can be pursued by providing draft proposals to be discussed via the AVTCORE working group email reflector.
