Abstract:
This document gives information on an RTP Control Protocol (RTCP)
Packet Type and RTCP Extended Report (XR) Block Type including
associated Session Description Protocol (SDP) parameters for Inter-
Destination Media Synchronization (IDMS). This document mandates the
use of the RTCP XR Block Type 12, which is used to collect media
playout information from participants in a group playing out
(watching, listening, etc.) a specific RTP media stream. This RTCP
XR Block Type is specified and registered with IANA by ETSI. The
RTCP packet type specified by this document is used 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.
