Abstract
A system and method for transmitting a plurality of video signals scalably coded into layers including a base layer and one or more enhancement layers and associated audio signals, if any, over a communication network for presentation to one or more end users. A layout to display the plurality of video signals is determined based on a set of criteria and only the data of the video signal layers that are necessary for displaying the video signals in the determined layout, and any associated audio signals, is selectively transmitted over the communication network.
