HYBRID SCALABLE DECODER AND METHOD FOR STANDARD-DEFINITION AND HIGH-DEFINITION VIDEO FORMATS ON A SINGLE-DISC

摘要

A kind of hybrid salable encoder (100 is disclosed, 600), method and medium, be used for video signal data is treated to a plurality of conversion coefficients, described a plurality of conversion coefficients are used for the basic layer that comprises and each of enhancement layer on dual, single-definition and high definition scale.Described encoder (100,600) comprising: double-deck resolving cell (110) is used for original high-definition signal data sequence is decomposed into base layer data and enhancement data; Single-definition encoder (112), it is couple to described resolving cell, is used for base layer data is encoded to the basic layer bit stream that embodies the standard definition data sequence; High definition encoder (124), it is couple to described resolving cell and described single-definition encoder, is used for the difference between high-resolution data and standard definition data is encoded to the enhancement layer bit-stream that embodies the high-resolution data sequence.
