Method for processing adjacent block information in video decoding macro-block prediction and boundary filtering

Abstract: The invention relates to a method for processing adjacent block information in video decoding macro-block prediction and boundary filtering, which belongs to the technical field of video decoding. The method comprises the following steps of: storing adjacent block information by ten registers; performing subscript mapping processing on a 4*4 segmented block at an upper left corner and performing offset calculation to obtain the numbers of the registers of a left block, an upper block, a right block and an upper left block; after processing is finished by the prior art, updating the subscript mapping until an entire macro-block is processed; and updating the macro-block of the register to obtain new line buffer content and the information of an adjacent register so as to process a next macro-block. The method is suitable for predicting the macro-block and calculating the intensity of boundary filtering in H.264 and AVS decoding, can effectively reduce the storage spaces of adjacent block registers, multiplexes and simplifies hardware design and improves video decoding efficiency.
