1. A video coding method, comprising: identifying, from content of pixel blocks of a frame of video data, which pixel blocks are likely to exhibit banding artifacts from a video coding/decoding process; identifying regions of the frame that are likely to exhibit banding artifacts based on the identified pixel blocks' locations with respect to each other; applying anti-banding processing to pixel blocks within a region; and coding the frame for transmission over a channel by a compression operation, the coding being applied to a frame comprised of the processed data of the anti-banding processed pixel blocks and source data of remaining pixel blocks.
