Claim 9:
10. An apparatus, comprising:
an input module configured to receive a current block of a picture;
a neighboring block buffer configured to store a first set of pixel data of one or more neighboring blocks of the current block;
a deblocking filter configured to perform a deblocking operation to the current block using pixel data of the current block and the first set of pixel data of the one or more neighboring blocks;
a filtered block buffer configured to store one or more completely filtered sub-blocks and one or more partially filtered sub-blocks; and
an output module configured to output an output block comprising the one or more completely filtered sub-blocks and a respective portion of each of the one or more partially filtered sub-blocks, the respective portion being adjacent to one of the completely filtered sub-blocks, wherein the deblocking filter is configured to perform the deblocking operation along at least one vertical or horizontal deblocking boundary of the current block by referencing a first number of pixels and revising a second number of pixels on each of two sides of the at least one vertical or horizontal deblocking boundary, and wherein:
the respective portion comprises a rectangular area having a width or length of a third number of pixels, and
the third number is equal to a difference between the first number and the second number.
