Title: RTP Control Protocol (RTCP) Extended Report (XR) Block for MPEG2
Transport Stream (TS) Program Specific Information (PSI) Independent
Decodability Statistics Metrics reporting
Reviewer: Enrico Marocco
Review Date: 2013-03-19

IESG Telechat Date: Unknown

Summary: This draft is ready for publication as a Standards Track RFC.
From an APPS point of view there no issues with this document, but a
bunch of nits the RFC Editor would have spotted anyway.


General note: ETSI TR 101 290 is mentioned in several places throughout
the document. It should be replaced with the actual reference ([ETSI]).

[Rachel]: Okay.

Abstract: The last sentence is really hard to read. I'm not sure I
entirely understand what it means, so I'll let it up to the authors to
propose a better wording.

[Rachel]: How about changing to the following sentence?

This document defines an RTP Control Protocol (RTCP) Extended Report (XR) Block that allows the reporting of MPEG2 TS Program Specific Information (PSI) Independent decodability statistics metrics for applications using transmissions of MPEG2 TS over RTP. 


S. 3, "Reserved" definition: s/senders ignored/senders and ignored/

[Rachel]: Okay.
