Analysis and Comparison of Multimedia Inter-stream and Group Synchronisation Algorithms

In this paper an analysis and comparison of multimedia synchronisation algorithms is presented. After presenting the three types of multimedia synchronisation (intra-stream, inter-stream and group synchronisation), only inter-stream and group synchronisation algorithms are considered. The main synchronisation techniques included in most of the analysed algorithms have also been classified. Finally, a table is presented with the main characteristics of each algorithm according to the techniques included and other critical parameters such as the use of global or locally available clocks, the suitability for stored contents or live contents, the synchronisation information added to the data packets, the use of Real Time Transport Protocol, etc. This work provides a good starting point to all the new researchers interested in multimedia synchronisation and multimedia systems.
