Media Presentation Synchronisation for Non-monolithic Rendering Architectures

Non-monolithic renderers are physically distributed media playback engines. Non-monolithic renderers may use a number of different underlying network connection types to transmit media items belonging to a presentation. There is therefore a need for a media based and inter-network- type synchronization algorithm. NeighbourCast is an algorithm for synchronising nodes in a wireless ad hoc network. In this paper, we introduce an efficient extension to NeighbourCast, that allows non-monolithic rendering nodes to be synchronised across multiple networks, during a media presentation. Our results show that our algorithm matches the requirements we enlist for non-monolithic renderer synchronisation. Our results meet the requirements imposed by lip synchronization research done earlier.
