   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.  Using the RTCP XR IDMS Reporting Block defined in
   this document, media playout information from participants in a
   synchronization group can be collected.  Based on the collected
   information, an RTCP IDMS Settings Packet can then be send to
   distribute a common target playout point to which all the distributed
   receivers, sharing a media experience, can synchronize.

   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.
