Abstract

Deblocking filters are disclosed (Fig. 2, item 20), where the nature of the filter is determined based upon the level of detail of a reconstructed video frame in the region in which the block boundary is located (Fig. 2, item 22). One embodiment of the method of the invention includes indentifying a boundary between two blocks of the reconstructed video frame, determining the level of detail of the reconstructed video frame in a region in which the block boundary is located (Fig. 2, item 24), wherein the region includes pixels from multiple columns of the reconstructed frame and includes at least one pixel that is not immediately adjacent the block boundary (See Fig. 2, item 26), and selecting a filter to apply to predetermined pixels on either side of the block boundary based upon the determined level of detail (See Fig. 2, item 30).
