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, wherein the blocks have vertical edges and horizontal edges forming outer boundaries of the blocks and starting with block element M 11 , the vertical edges and the horizontal edges of the blocks of a macroblock comprising: determining a context area containing the blocks of 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, wherein the block elements K rs where r=3 to 6 and s=3 to 6 correspond to the block elements M mn where m=1 to 4 and n=1 to 4 of the first matrix M, and Filtering the vertical edges and the horizontal edges of the blocks of the context area starting with block element K 11 of the second matrix K according to the coding standard for image information.
