TWO-LAYER DECODING FOR HYBRID HIGH-DEFINITION DVD |
摘要 |
<p>A hybrid high-definition decoder and method are disclosed, for processing signal data as a plurality of block transform coefficients for each of base layer data and enhancement layer data, where the decoder includes a standard-definition decoder for decoding the standard-definition data from a base layer bitstream embodying a standard-definition data sequence, a high-definition decoder coupled to the standard-definition decoder for decoding the difference between the high-definition data and the standard-definition data from an enhancement layer bitstream stored as picture user data embodying a high-definition data sequence, and a two-layer composition unit for composing a high-definition signal data sequence from the standard-definition data and the difference between the high-definition data and the standard-definition data.</p> |
