DEVICES AND METHODS FOR CONTEXT REDUCTION IN LAST SIGNIFICANT COEFFICIENT POSITION CODING

摘要

A method of video encoding includes encoding a position of a last non-zero coefficient within a video block having a first width. The position of the last non-zero coefficient is provided as a string of binary values, wherein each binary value in said string corresponds to a bin index value. The method also includes determining a context index value for each bin index value, wherein the context index value for each bin index value is configured to be shared across two or more blocks of different widths.
