          Technical Summary

This document defines a new report block type within the framework of RTP
Control Protocol (RTCP) Extended Reports (XR).  One of the initial XR
block types is the Loss Run Length Encoding (RLE) Report Block.  This
conveys the information regarding the individual Real-time Transport
Protocol (RTP) packet receipt and loss events experienced during the RTCP
interval preceding the transmission of the report.  The new report, which
referred to as the Post-repair Loss RLE Report, carries the information
regarding the remaining lost packets after all loss-repair methods are
applied.  By comparing the RTP packet receipts/losses before and after the
loss repair is completed, one can determine the effectiveness of the
loss-repair methods in an aggregated fashion.  This document also defines
the signaling of the Post-repair Loss RLE Report in the Session
Protocol (SDP).  

Working Group Summary
The document has been reviewed by the AVT working group to ensure
consistency with RTCP XR.
