PROBLEM TO BE SOLVED: To provide an apparatus and method for client-side composition of video streams.SOLUTION: A method includes receiving, by a video display device 103, a multiplexed data stream from a remote video server 102. The multiplexed data stream includes substreams, where the substreams includes a descriptor substream, at least one media substream, and a composition-instruction substream. The method further includes demultiplexing, by the video display device 103, the multiplexed data stream into the substreams according to the descriptor substream and displaying, by the video display device 103, the at least one media substream on a display screen 104 according to the composition-instruction substream, where the compositing-instruction substream includes instructions on a composition of the at least one media substream. |
