Abstract
A hybrid scalable encoder, method, and media are disclosed for processing video signal data as a plurality of block transform coefficients for each of a base layer and an enhancement layer included on a dual standard-definition and high-definition disc. The encoder includes a two-layer decomposition unit for decomposing an original high-definition signal data sequence into base layer data and enhancement layer data, a standard-definition encoder coupled to the decomposition unit for encoding the base layer data as a base layer bitstream embodying a standard-definition data sequence, and a high-definition encoder coupled to the decomposition unit and the standard-definition encoder for encoding the difference between the high-definition data and the standard-definition data as an enhancement layer bitstream embodying a high-definition data sequence.
