Abstract
Methods for decoding frames of compressed video information are disclosed. Each frame includes a plurality of blocks having a prediction stage parameter and a residual error attribute. One method includes categorizing each of the blocks into categories based on at least one of the prediction stage parameter or the residual error attribute, determining a loop filter strength value to each of the categories, and filtering the boundary adjacent to at least one of the blocks using the loop filter strength assigned to the category in which that block is categorized.
