    RTP Control Protocol (RTCP) Extended Report (XR) Block for MPEG2
  Transport Stream (TS) Program Specific Information (PSI) Independent
               Decodability Statistics Metrics reporting
               draft-ietf-xrblock-rtcp-xr-decodability-09

Abstract

   An MPEG2 Transport Stream (TS) is a standard container format used in
   the transmission and storage of multimedia data.  Unicast/Multicast
   MPEG2 TS over RTP is widely deployed in IPTV systems.  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 related to
   transmissions of MPEG2 TS over RTP.

1.  Introduction

1.1.  MPEG2 Transport Stream Decodability Metrics

   The European Telecommunications Standards Institute (ETSI) has
   defined a set of syntax and information consistency tests and
   corresponding indicators [ETSI] that are recommended for the
   monitoring of MPEG2 Transport Streams [ISO-IEC.13818-1.2007].  The
   tests and corresponding indicators are grouped according to priority:
