    Abstract: A video processing system includes a data buffer and a storage controller. The data buffer is shared between a plurality of in-loop filters, wherein not all of the in-loop filters comply with a same video standard. The storage controller controls data access of the data buffer, wherein for each in-loop filter granted to access the data buffer, the data buffer stores a partial data of a picture processed by the in-loop filter. Another video processing system includes a storage device and a storage controller. The storage controller adaptively determines a size of a storage space according to a tile partition setting of a picture to be processed by an in-loop filter, and controls the storage device to allocate the storage space to serve as a data buffer for storing data of the in-loop filter.

    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.
