A method of communicating a traffic stream over a communications network comprising a variable traffic bandwidth

摘要

A method of communicating a traffic stream 200a over a variable traffic bandwidth comprises: processing the traffic stream to produce a modified traffic stream 200b comprising a plurality of traffic clips 210, each clip comprising a plurality of traffic frames 230; processing the traffic frames of each clip to produce a set of traffic structures corresponding to each clip, the structures of the set comprising a component of the traffic frames, such that an assembly of corresponding components of the structures of each set collectively comprise the respective traffic frame; communicating the structures of each set sequentially wherein the number of structures communicated is arranged to vary according to the variable traffic bandwidth. Preferably each traffic structure corresponds with an iterative processing step of the traffic frames comprising an iterative extraction of components from the frames, each iteration including further components in the representation of each frame.
