    摘要: Systems and methods are disclosed for supporting a pull data flow scheme in an A/V decoder. One method relates to processing data using an A/V decoder comprising receiving the data from a data stream and recovering a system time reference from the received data. The received data is processed using a clock asynchronous to the system time reference and pulled into an output device using a system adapted to support a pull data flow. The processed data is output using a time reference locked to the system time reference.

    摘要: A video processing system may be operable to utilize multi-band sharpening to process luma signals for image signals. The luma signal may be decomposed into a plurality of frequency band components, wherein each component may be processed separately using different sharpening gains and/or offsets. The multi-band processed components may be combined to generate sharpened output luma signals. The multi-band sharpening may be performed utilizing peaking processing, and the input luma signal and/or LTI sharpened luma signals may be combined with the multi-band peaking sharpened signals to generate the sharpened output luma signals. Corresponding chroma signals may also be adjusted to generate sharpened output chroma signals. Luma and/or chroma sharpening operations may be further adjusted based on coring, clipping avoidance, luma statistics, color region detections, and/or curve control parameters. Sharpened output image signals may be generated based on the sharpened output luma signals and the sharpened output chroma signals.

    摘要: A system and method for processing video information. Various aspects of the present invention may provide a decoder module that decodes block encoded video information. The system may, for example, include a first memory module, communicatively coupled to the decoder module, that stores video processing information utilized by the decoder module for decoding a current video block from a current video frame. The system may also, for example, include a second memory module, communicatively coupled to the decoder module, that stores reference video information from a previous video frame utilized by the decoder module for decoding the current video block. In a non-limiting exemplary scenario, the first memory module and the second memory module may be communicatively coupled to the decoder module with independent respective data and/or address buses.
