ABSTRACT:
A method and apparatus are disclosed for adaptively selecting a deblocking filter used in video de-blocking. Determinations are made as to whether each of a set of spatially adjacent video blocks is inter-coded or intra-coded and whether each of said adjacent video blocks is field-coded or frame-coded. A deblocking filter is selected (an interlace deblocking filter or a frame deblocking filter) based on the determinations. The selected deblocking filter is used to filter across a boundary between adjacent video blocks.
