Abstract

Inter-Destination Media Synchronization (IDMS) is essential in the emerging media consumption paradigm, which is radically evolving from passive and isolated services towards dynamic and interactive group shared experiences. This paper concentrates on improving a standardized RTP/RTCP-based solution for IDMS. In particular, novel Early Event-Driven (EED) RTCP feedback reporting mechanisms are designed to overcome latency issues and to enable higher flexibility, dynamism and accuracy when using RTP/RTCP for IDMS. The faster reaction on dynamic situations (e.g., detection of asynchrony or channel change delays) and a finer granularity for synchronizing media-related events, while preserving the RTCP bandwidth bounds, are validated through simulation tests.
