Abstract
A symbol sequence is entropy-encoded using a table of symbol occurrences, and an integer value f is used to encode the table of symbol occurrences. The integer value f is used to adaptively decode the table of symbol occurrences, including (i) decoding each entry of a cumulative table of symbol occurrences by successively subdividing decoding ranges of the cumulative table of symbol occurrences at their respective middle indexes and, for each decoding range: calculating, from decoded entries of the cumulative table of symbol occurrences, an entry at a first index+f mod(an entry at a last index−the entry at the first index+1) to decode an entry at the respective middle index of the decoding range, and calculating f div(the entry at the last index−the entry at the first index+1) to update f; (ii) calculating the table of symbol occurrences from the decoded entries of the cumulative table of symbol occurrences; and applying the decoded table of symbol occurrences to entropy-decode the received encoded symbol sequence.
