     RTP Control Protocol (RTCP) Extended Report (XR) Block for TS
                Decodability Statistics Metric reporting
               draft-ietf-xrblock-rtcp-xr-decodability-01

Abstract

   Transport Stream (TS) is a standard container format used in the
   transmission and storage of multimedia data.  Unicast/Multicast/
   Broadcast MPEG-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 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
   corresponding indicators [ETSI] that are recommended for the
   monitoring of MPEG-2 Transport Streams [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 defined by ETSI [ETSI] and defines a new block type to
   augment those defined in Freidman, et al. [RFC3611] for use with
   Transport Stream (TS) [ISO-IEC.13818-1.2007].  The new block type
