Abstract
A method of simplifying deblock filtering of video blocks of an enhanced layer of scalable video information is disclosed which includes selecting an adjacent pair of video blocks, determining whether boundary strength of the video blocks is a first value, evaluating first conditions using component values of a first component line if the boundary strength is not the first value, and bypassing deblock filtering between the video blocks if the boundary strength is the first value or if any of the first conditions is false. The method may include bypassing evaluating conditions and deblock filtering associated with the maximum boundary strength. The method may include bypassing evaluating second conditions and bypassing corresponding deblock filtering if the intermediate edge is a horizontal edge. The method may include bypassing less efficient memory reads associated with component values used for evaluating the second conditions.
