Purpose: In response

Referenced liaison: Liaison statement to IETF AVT on MPEG Green Metadata (https://datatracker.ietf.org/liaison/1762/)

Body: IETF AVTCORE Working Group acknowledges and appreciates your work on updating the specifications of the GREEN-MPEG standard. 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.
