Abstract:
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.
