The RTCP XR Block Type, registered with IANA based on an ETSI specification, is used to collect media play-out information from participants in a group playing-out (watching, listening, etc.) a specific RTP media stream. The RTCP packet type specified by this document is used to distribute a common target play-out 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.}, }
