RTP Control Protocol (RTCP) Extended Report (XR) Block for MPEG2
Transport Stream (TS) Program Specific Information (PSI) Decodability
Statistics Metrics Reporting
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 decodability statistics metrics
related to transmissions of MPEG2 TS over RTP. The metrics specified
in the RTCP XR block are related to Program Specific Information
(PSI) carried in MPEG TS.

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:
First priority: Necessary for decodability (basic monitoring)
Second priority: Recommended for continuous or periodic monitoring
