Abstract

This document defines a new report block type within the framework ofRTP Control Protocol (RTCP) Extended Reports (XRs). One of theinitial XR report block types is the Loss Run Length Encoding (RLE)Report Block. This report conveys information regarding theindividual Real-time Transport Protocol (RTP) packet receipt and lossevents experienced during the RTCP interval preceding thetransmission of the report. The new report, which is referred to asthe Post-repair Loss RLE report, carries information regarding thepackets that remain lost after all loss-repair methods are applied.By comparing the RTP packet receipts/losses before and after the lossrepair is completed, one can determine the effectiveness of the loss-repair methods in an aggregated fashion. This document also definesthe signaling of the Post-repair Loss RLE report in the SessionDescription Protocol (SDP). [STANDARDS-TRACK]
