Design, development and evaluation of an adaptive and standardized RTP/RTCP-based IDMS solution

Abstract

Inter-Destination Media Synchronization (IDMS) is essential for enabling pleasant shared media experiences. The goal of my PhD thesis is to design, develop and evaluate an advanced RTP/RTCPbased IDMS solution fitting the requirements of the emerging distributed media consumption paradigm. In particular, standard compliant extensions to RTCP are being specified to allow for an accurate, adaptive and dynamic IDMS control when using RTP for streaming media. Moreover, the feasibility and suitability of several architectural schemes for exchanging the IDMS information, algorithms for allowing a dynamic IDMS monitoring and control, as well as adjustment techniques are being investigated. Objective and subjective testing are being conducted to validate the satisfactory performance of our IDMS solution and to provide insights about the users' tolerance on asynchrony levels in different IDMS scenarios.

Self-Organized Inter-Destination Multimedia Synchronization For Adaptive Media Streaming

“…Therefore, a peer or the source is selected as the master to which the media playback of all clients is synchronized. In [4] and [16] a SMS approach using RTP and RTCP for achieving IDMS is presented. Therefore, the receiver report message and the application-specific message of RTCP were extended.…”

Merge and forward

“…In [1], [8] and [9] RTP/RTCP is used to provide IDMS for a group of peers. This approach extends the RTCP protocol by extending the sender and receiver reports in order to signal timing and control information.…”
