  RTCP XR Report Block for TS Decodability Statistics Metric reporting
               draft-ietf-xrblock-rtcp-xr-decodability-00

Abstract

   Transport Stream is a standard container format used in the
   transmission and storage of multimedia data.  Unicast/Multicast/
   Broadcast MPEG-TS over RTP is widely adopted in the IPTV deployment.
   This document defines an RTCP XR Report Block that allows the
   reporting of decodability statistics metrics related to transmissions
   of MPEG-TS over RTP.

1.  Introduction

   The European Telecommunications Standards Institute (ETSI) has
   defined a set of syntax and information consistency tests and
   resulting indicators [ETSI] recommended for the monitoring of MPEG-2
   Transport Streams (TS) [ISO-IEC.13818-1.2007].  The tests and
   corresponding indicators are grouped according to priority:

   o  First priority - Necessary for de-codability (basic monitoring)
   o  Second priority - Recommended for continuous or periodic
      monitoring
   o  Third priority - Recommended for application-dependant monitoring

   This draft is based on information consistency tests and resulting
   indicators in the [ETSI] and defines a new block type to augment
   those defined in [RFC3611] for use with Transport Stream (TS)
   [ISO-IEC.13818-1.2007].  The new block type supports reporting of the
   number of each indicator in the first and second priority;third
   priority indicators are not supported.  This new block type can be
   useful for measuring content stream or TS quality by checking TS
   header information [ETSI] and identifying the existence, and
   characterizing the severity, of bitstream packetization problem which
   may affect users' perception of a service delivered over RTP; it may
   also be useful for verifying the continued correct operation of an
