RTP Control Protocol (RTCP) Extended Report (XR) Block for MPEG-2
Transport Stream (TS) Program Specific Information (PSI) Independent
Decodability Statistics Metrics Reporting
Abstract
An MPEG-2 Transport Stream (TS) is a standard container format used
in the transmission and storage of multimedia data. Unicast/
multicast MPEG-2 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 MPEG-2 TS decodability
statistics metrics related to transmissions of MPEG-2 TS over RTP.
The metrics specified in the RTCP XR block are not dependent on
Program Specific Information (PSI) carried in MPEG-2 TS.

RFC 6990 RTCP XR TS Decodability August 2013
1. Introduction
1.1. MPEG-2 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 MPEG-2 Transport Streams [ISO-IEC.13818-1.2013]. The
tests and corresponding indicators are grouped according to priority:
o First priority - Necessary for decodability (basic monitoring)
o Second priority - Recommended for continuous or periodic
monitoring
o Third priority - Recommended for application-dependent monitoring
