Abstract

A method is provided for processing multilayer bit streams that includes receiving the multilayer bit streams of Scalable Video Code (SVC) each having a base layer and at least one enhancement layer. One or more of the enhancement layers are extracted in whole or in part from at least one of the multilayer bit streams so that the multilayer bit streams are collectively reduced in their total bandwidth. Each of the extracted bit streams are rewritten to a single layer bit stream. The single layer bit streams are then multiplexed to form a multiplexed single layer bit stream that is non-SVC.
