Media Presentation Synchronisation for Non-monolithic Rendering Architectures

Non-monolithic renderers are physically distributed me- dia 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 a algo- rithm for synchronising nodes in a wireless ad hoc network. In this paper, we introduce an efficient extension to Neigh- bourCast, 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 syn- chronisation. Our results meet the requirements imposed by lip synchronization research done earlier.
