    Abstract: A method and apparatus for SAO (sample adaptive offset) processing in a video decoder are disclosed. Embodiments according to the present invention reduce the required line buffer associated with the SAO processing. According to one embodiment, tri-level comparison results for one deblocked pixel row or column of the image unit are determined according to SAO type of the deblocked pixel row or column. The tri-level comparison results are stored in a buffer and the tri-level comparison results are read back from the buffer for SAO processing of the subsequent row or column from a subsequent image unit. The comparison results correspond to “larger”, “equal” and “smaller” states. The comparison results can be stored more efficiently.

    Abstract: A data processing apparatus has a compressor and an output interface. The compressor generates an output multimedia data according to an input multimedia data. The output interface packs the output multimedia data into an output bitstream, and outputs the output bitstream to another data processing apparatus via a camera interface. The camera interface is a camera serial interface (CSI) standardized by a Mobile Industry Processor Interface (MIPI). In addition, the compressor adaptively adjusts a compression algorithm according to context characteristics in the input multimedia data, power supply status, operational status of a storage device, image capture characteristic, configuration of the another data processing apparatus, and/or compression algorithm supported by the another data processing apparatus. Further, the another data processing apparatus adaptively adjusts a de-compression algorithm according to a compression algorithm supported by the compressor.
