Claim One:
1. A method for deblocking filtering a macroblock based on a coding standard for image information which is saved in macroblocks, which are arranged adjacent to each other horizontally in macroblock rows and adjacent to each other vertically in macroblock columns, wherein each macroblock is formed from blocks which are arranged adjacent to each other horizontally in block rows m and adjacent to each other vertically in block columns n and form block elements M mn where m=1 to 4 and n=1 to 4 of a first matrix M, the method comprising: determining a context area surrounding a first macroblock to be filtered, said context area being formed from blocks which are arranged adjacent to each other horizontally in block rows o and adjacent to each other vertically in block columns p and form block elements K op where o=1 to 7 and p=1 to 7 of a second matrix K, block elements K rs of the second matrix K where r=3 to 6 and s=3 to 6 correspond to the blocks of the block elements M mn where m=1 to 4 and n=1 to 4 of the first matrix M, the context area comprising the blocks of the block elements K op that do not correspond to the blocks of the block elements M mn of the first matrix M; filtering blocks of the context area that surround the first macroblock starting with block element K 11 of the second matrix K according to the coding standard for image information such that the blocks of the block elements K op of the second matrix K that correspond to the blocks of the block elements M mn where m=1 to 4 and n=1 to 4 are not filtered during the filtering of the blocks of the context area that surround the first macroblock; and filtering the blocks of the first macroblock after the filtering of the blocks of the context area that surround the first macroblock.
