Abstract: A method of encoding a frame to generate an output bitstream has following steps: dividing the frame into partitions; dividing each of the partitions into blocks, wherein each of the blocks is composed of pixels; assigning a first segmentation identifier to each of first blocks located at partition boundaries each between two adjacent partitions within the frame, wherein the first blocks belong to a first segment, and the first segmentation identifier is signaled per first block; and encoding each of the blocks. The step of encoding each of the blocks includes: generating reconstructed blocks for the blocks, respectively; and configuring an in-loop filter by a predetermined in-loop filtering setting in response to the first segmentation identifier, wherein the in-loop filter with the predetermined in-loop filtering setting does not apply in-loop filtering to each reconstructed block corresponding to the first segment.
