FIMV-MFC V1.0
H.263 Annex J Deblocking filter
The filtering is performed on 8x8 block edges, except across picture edge. The horizontal edges are filtered first
from top to bottom, and then vertical edges are filtered from left to right. The pixels that are used in filtering across
a horizontal edge need not be influenced by previous filtering across a vertical edge. Parameters for filtering
operation are set by the BIT processor.
The Figure 21.32 highlights the valid data output in H.263 Annex J mode.
