Technical Summary

This document defines an RTP Control Protocol (RTCP) Extended Report
(XR) Block including two new segment types and associated SDP
parameters that allow the reporting of MOS Metrics for use in a range
of RTP applications.

Working Group Summary

The WG reviewed carefully the document several times and there is
good support behind it.

Document Quality

Two vendors indicated that they have similar functionality in their
code and intentions to implement the standard block when approved.
There was one important change to notice which resulted from the SDP
Expert Review which led to the change of the title of the document from
QoE to MOS Metric reporting, which defines better the scope of the document.


Dan Romascanu is the Document Shepherd. Gonzalo Camarillo is the Responsible
Area Director.
