Abstract:
1. A method, comprising: receiving a compressed video bitstream comprising a first codeword of compressed digital media data; decoding the compressed video bitstream, the decoding comprising decoding the first codeword into a first digital media data value by referencing a codeword table, the codeword table associating the first codeword with the first digital media data value and associating a second codeword with a second digital media data value; incrementing a first counter for counting occurrences of the first digital media data value being decoded from the compressed video bitstream during the decoding; comparing a value of the first counter with a value of a second counter, the second counter for counting occurrences of a second digital media data value being decoded from the compressed video bitstream during the decoding; and changing the codeword table such that the first codeword is associated with the second digital media value and the second codeword is associated with the first digital media value if the value of the first counter and the value of the second counter are equal.
