Claim Text:
1. A method of encoding of video data, the method comprising: determining an initial loop filter level for a frame of the video data according to a factor associated with target bit rate, frame width and frame height, wherein the initial loop filter level is a loop filter parameter; incorporating loop filter information associated with the initial loop filter level in a bitstream corresponding to compressed video data; applying loop filtering to at least a part of reconstructed frame to generate restored video data; and providing the restored video data; wherein said determining the initial loop filter level determines at least one filter parameter selected from a group consisting of loop_filter_level and sharpness_level; and wherein a segment-level initial loop filter level is determined for each of segments of the frame according to quality setting for said each of the segments based on whether segmentation is on or off, and wherein the segment-level initial loop filter level is used as the initial loop filter level for said each of segments; wherein said determining the initial loop filter level determines at least one filter parameter selected from a group consisting of loop_filter_level and sharpness_level; and wherein a segment-level initial loop filter level is determined for each of segments of the frame according to quality setting for said each of the segments based on whether segmentation is on or off, and wherein the segment-level initial loop filter level is used as the initial loop filter level for said each of segments.
