Abstract
A video decoding apparatus for decoding an encoded video bitstream having frames of video data encoded in rows of macroblocks. The video decoding apparatus comprises a parsing unit configured to receive the encoded video bitstream and to interpret the encoded video bitstream to generate items of macroblock information to be used for reconstructing the video frames of video data. The parsing unit is configured to store the items of macroblock information in a memory in bitstream order. The video decoding apparatus further comprises a line control unit configured to generate line control information associated with each row of macroblocks, the line control information comprising a sequence of pointers to the items of macroblock information stored in the memory, such that sequentially reading the sequence of pointers accesses the items of macroblock information in raster scan order. The line control information is stored in said memory in association with said items of macroblock information. A reconstruction pipeline is configured to reconstruct the frames of video data with reference to the line control information.
