WebSystems and methods are described for simplifying the sub-bitstream extraction and the rewriting process. In an exemplary method, a video is encoded as a multi-layer scalable bitstream including at least a base layer and a first non-base layer. The bitstream is subject to the constraint that the image slice segments in the first non-base layer each …
