VIDEO ENCODING METHOD ENABLING HIGHLY EFFICIENT PARTIAL DECODING OF H.264 AND OTHER TRANSFORM CODED INFORMATION

摘要

PROBLEM TO BE SOLVED: To provide methods and apparatus for processing multimedia data enabling efficient partial decoding of transform coded data.SOLUTION: A decoder device receives transform coefficients associated with multimedia data. The decoder device determines a set of multimedia samples to be reconstructed. In one aspect, the set of samples to be reconstructed is a subset of a matrix of transformed multimedia samples. The decoder device determines a set of transform coefficients to be used to reconstruct the multimedia samples. In one aspect, the transform coefficients are used to scale partial basis images associated with the encoding method used to generate the transform coefficients, resulting in reconstructed multimedia samples.
