ABSTRACT:
A method of entropy encoding image or video data may include entropy encoding a number of blocks independently and in parallel to generate a number of bit streams. At least one of the number of bit streams may include an assumed value in place of a value that would be determined by another bit stream. The method may also include selectively correcting the assumed value based on a value in another one of the number of bit streams. The number of bit streams may be combined into an output, entropy encoded bit stream corresponding to the number of blocks.
