Abstract:
1. A method of coding a coded unit (CU) of video, the method comprising: maintaining, by a video coding device, one or more variable length coding (VLC) tables that map VLC codewords to a plurality of prediction modes; counting a number of occurrences of each of the prediction modes in a set of the prediction modes for a current frame; adjusting a mapping of the set of prediction modes to codewords based on the number of occurrences of each prediction mode; resetting the mapping of the set of prediction modes to codewords in response to receiving a new frame of video following the current frame; receiving a first VLC codeword associated with a CU of the current frame; determining one of the prediction modes for the CU based on the first VLC codeword; and reconstructing the CU using the prediction mode.
