This document defines a new report block type within the framework of
RTP Control Protocol (RTCP) Extended Reports (XRs).  One of the
initial XR report block types is the Loss Run Length Encoding (RLE)
Report Block.  This report conveys 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 is referred to as
the Post-repair Loss RLE report, carries information regarding the
packets that remain lost 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
Description Protocol (SDP).  [STANDARDS TRACK]
