Abstract Abstract
This document defines a new RTP Control Protocol (RTCP) Packet Type This document defines a new RTP Control Protocol (RTCP) Packet Type
and an RTCP Extended Report (XR) Block Type to be used for achieving and an RTCP Extended Report (XR) Block Type to be used for achieving
Inter-Destination Media Synchronization (IDMS). IDMS is the process Inter-Destination Media Synchronization (IDMS). IDMS is the process
of synchronizing playout across multiple geographically distributed of synchronizing playout across multiple geographically distributed
media receivers. Using the RTCP XR IDMS Report Block defined in this media receivers. Using the RTCP XR IDMS Report Block defined in this
document, media playout information from participants in a document, media playout information from participants in a
synchronization group can be collected. Based on the collected synchronization group can be collected. Based on the collected
