20110222607 | DEBLOCKING FILTERING METHOD AND DEBLOCKING FILTER - An exemplary deblocking filtering method includes checking if at least one of two adjacent blocks is an intra-coded block and accordingly generating a checking result; and applying a deblocking filtering scheme with a clipping range to the two adjacent blocks by a deblocking filtering circuit as long as the checking result indicates that at least one of the two adjacent blocks is the intra-coded block. | 2011-09-15 |
