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.

Abstract: PROBLEM TO BE SOLVED: To provide techniques for interpolating video frames at decoding.SOLUTION: A frame interpolation operation is dynamically adjusted based on analysis of information associated with one or more video frames. In response to the analysis of the information associated with the one or more frames, an interpolation control module adjusts the frame interpolation operation in a number of different manners. For example, the interpolation control module may dynamically enable or disable motion compensated frame interpolation, select a different type of interpolation, select a video frame prediction mode to be used in the motion compensated frame interpolation, or select different threshold values for frame interpolation.
