Abstract: A data processing apparatus has a first compressor, a second compressor, a first output interface, and a second output interface. The first compressor generates first compressed display data by performing compression upon display data of a first partial region of a frame according to a first compression order. The second compressor generates second compressed display data by performing compression upon display data of a second partial region of the frame according to a second compression order. There is a boundary between the first partial region and the second partial region. In a horizontal direction, the first compression order on one side of the first boundary is opposite to the second compression order on another side of the first boundary. The first and second output interfaces output the first and second compressed display data via a first display port and a second display port of a display interface, respectively.

Abstract: A method and apparatus for applying DF processing and SAO processing to reconstructed video data are disclosed. The DF processing is applied to a current access element of reconstructed video data to generate DF output data and the deblocking status is determined while applying the DF processing. Status-dependent SAO processing is applied to one or more pixels of the DF output data according to the deblocking status. The status-dependent SAO processing comprises SAO processing, partial SAO processing, and no SAO processing. The SAO starting time for SAO processing is between the DF-output starting time and ending time for the current block. The DF starting time of a next block can be earlier than the SAO ending time of the current block by a period oft, where t is smaller than time difference between the DF-output starting time and the DF starting time of the next block.
