This memo describes an RTCP feedback message format for the ISO/IEC International Standard 23001-11, known as Energy Efficient Media Consumption (Green metadata), developed by the ISO/IEC JTC 1/SC 29/ WG 3 MPEG System. The RTCP payload format specified in this document enables receivers to provide feedback to the senders and thus allows for short-term adaptation and feedback-based energy efficient mechanisms to be implemented. The payload format has broad applicability in real-time video communication services.
