The IESG has received a request from the Audio/Video Transport Core Maintenance WG (avtcore) to consider the following document: - 'Inter-destination Media Synchronization using the RTP Control Protocol (RTCP)' <draft-ietf-avtcore-idms-09.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2013-06-11. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. 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. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-avtcore-idms/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-avtcore-idms/ballot/ No IPR declarations have been submitted directly on this I-D.
