Technical Summary:

This document defines a new RTP Control Protocol (RTCP) Packet Type and 
RTCP Extended Report (XR) Block Type to be used for achieving Inter-
Destination Media Synchronization (IDMS).  IDMS is the process of 
synchronizing playout across multiple geographically distributed media 
receivers. Typical use cases in which IDMS is usefull are social TV, 
shared  service control (i.e. applications where two or more 
geographically  separated users are watching a media stream together), 
distance  learning, networked video walls, networked loudspeakers, etc.

Working Group Summary:

This document went through a working group last call. There were 
comments and the document was updated to resolve all comments. The work 
started in ETSI and since it have to do with RTCP it was brought to the 
IETF AVTCore WG. The last issue that took some time was to update the 
ETSI document clarifying that the change control will be at the IETF.

Document Quality:

The document got good reviews from AVTcore members.
