US 8,149,926 B2 · Generating edge masks for a deblocking filter

Abstract

A deblocking unit may include a buffer, an edge mask generator, and a deblocking filter. The buffer may store video data including blocks. The blocks may correspond to at least a portion of a macroblock. The edge mask generator may generate a particular edge mask that defines edges between blocks to be deblocked. The edge mask generator may include an edge mask memory to store a number edge masks and logic to choose the particular edge mask among the number of edge masks. The logic may choose based on a type of the video data in the buffer and a position offset of the macroblock. The deblocking filter may deblock edges between blocks of video data in the buffer based on the particular edge mask from the edge mask generator.

Dependent claims

An apparatus, comprising:

a memory including a plurality of tables that include edge mask information that identifies edges of blocks of video data to be deblock filtered;
first logic to determine whether data to be deblock filtered is luminance or chrominance data and to specify a table index for selecting one table of edge mask information among the plurality of tables based at least in part on whether the video data to be deblock filtered is luminance or chrominance data;
and
a combiner to combine the table index with a macroblock position offset, the macroblock position offset indicating a particular macroblock region in the video data to be deblock filtered, to produce a combined index to specify a particular data entry within the one table, the particular entry corresponding to at least one set of edge mask information used to deblock filter the video data.
