Example 1
4 shows a codec device for video or image deblocking filtering, including a filter mode decider, a deblocking filter device for deblocking filtering macroblock data, and a time division for time-sharing output. Multiplexing device. Figure 5 is a diagram showing sample pixel points involved in deblocking filtering of a 4x4 block horizontal or vertical boundary using the deblocking filtering method employed by the present invention. Among them, the thick line indicates the block boundary that needs to be deblocked, and p0, p1, q0, and q1 represent two sample pixels on each side of the block boundary. 6 is a block boundary deblocking filtering apparatus for performing deblocking filtering on a block boundary by a conventional deblocking filtering method, and p0, p1, q0, q1 represent four sample pixel points input to a block boundary deblocking filtering device, P0, P1, Q0, and Q1 represent the pixel values of the original sample pixel points p0, p1, q0, and q1 after block de...
