    Abstract: 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.

    Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and method for decoding video data while maintaining a target video quality using an integrated error control system including error detection, resynchronization and error recovery.SOLUTION: Robust error control can be provided by a joint encoder-decoder functionality including multiple error resistance designs. In one aspect, error recovery may be an end-to-end integrated multi-layer error detection, resynchronization and recovery mechanism designed to achieve reliable error detection and error localization. The error recovery system may include cross-layer interaction of error detection, resynchronization and error recovery subsystems. In another aspect, error handling of a scalable coded bitstream is coordinated across a base layer and an enhancement layer of scalable compressed video.
