This document defines an RTP Control Protocol (RTCP) Extended Report (XR)
block that allows reporting of a post-repair loss count metric for a range 
of RTP applications.  In addition, another metric, repaired loss count, is 
also introduced in this report block for calculating the pre-repair loss 
count when needed, so that the RTP sender or a third-party entity is able 
to evaluate the effectiveness of the repair methods used by the system.

This document is a product of the Metric Blocks for use with RTCPs Extended Report Framework Working Group of the IETF.

This is now a Proposed Standard.
