Enforcing Multipoint Multimedia Synchronisation in Videoconferencing Applications

This paper deals with the problem of multimedia synchronisation in fully meshed multipoint videoconferencing applications. This work relies on previous work dealing with multimedia synchronisation in point to point videoconferencing: Up to now, the two main approaches are based on (1) timeline or on (2) temporal intervals composition. But, the first approach is not suited for multimedia data, and the second not suited for multipoint synchronisation. This paper then proposes a hybrid synchronisation solution taking advantage of the two preceding approaches. A multipoint videoconferencing tool based on this hybrid solution, called Confort, has been designed, developed, implemented and evaluated. This paper then deals with implementation details, as well as evaluation measurements.
