Abstract
In one embodiment, four horizontal successive pixels are first filtered by a decoder in a digital video appliance based on a determined horizontal filtering coefficient. Two pixels of the four horizontal successive pixels are in a first block and two pixels of the four horizontal successive pixels are in a second block. Then four vertical successive pixels are filtered by the decoder based on a determined vertical filtering coefficient. Two pixels of the four vertical successive pixels are in the first block and two pixels of the four vertical successive pixels are in a third block.
