    摘要： A classified adaptive spatio-temporal creation process is utilized to translate data from one format to another. This process creates new pixels by applying a filter selected on an output pixel by pixel basis which has been adaptively chosen from an application-specific set of three-dimensional filters. In one embodiment, a standard orientation is chosen, which is defined according to each output data position. Input data is flipped to align the output data position with the output position of the standard orientation. A classification is performed using the flipped input data and an appropriate filter is selected according to the classification. The filter is then executed to generate the value of the output data point.

    摘要： A system and method for decoding a signal comprising fixed-length data (FL-data) and variable length data (VL-data) is disclosed. In one embodiment, groups of fixed length data (FL-data) and blocks of variable length data (VL-data) are stored in a predetermined space. Each group of FL-data corresponds to a block of VL-data. The blocks of VL-data are retrieved by referencing corresponding groups of FL-data. In one embodiment, this system and method permits bidirectional recovery of data. In one embodiment, this is used in the transmission of video signals over a potentially lossy communications channel.

    摘要： The present invention provides a mechanism for preventing quality degradation of decoded data during the decoding of encoded data. In one embodiment, error propagation is detected and corresponding data is flagged. An error recovery process is then applied to the flagged data. In an alternate embodiment, scores for hypotheses are calculated for lost/damaged data. A score distribution is used for detection of the false hypotheses. The data are flagged if their score distribution is within a range defined by a threshold and an error recovery process is applied to recover those data having associated error flags set.

    摘要： A method, apparatus, and article of manufacture for restoring a deteriorated signal to an undeteriorated signal. A deteriorated signal consists of a plurality of deteriorated and undeteriorated data points. For each deteriorated data point, a plurality of class types is created based upon characteristics of the area containing the deteriorated data point. The data point is classified with respect to one of the plurality of class types and assigned a corresponding input signal class. The undeteriorated signal is generated by adaptively filtering the deteriorated input signal in accordance with the input signal classification result. More than one classification method is used to create the plurality of class types. Created classes may include a motion class, an error class, a spatial class or a spatial activity class. A spatial class is modified according to a spatial symmetry.
