| Abstract(in English) | A recently introduced family of entropy coders known as Asymmetric Numeral Systems (ANS) includes several variants. The tabled variant (tANS), which may be the best in compression performance, is suitable for static use, but it is not appropriate when the probability distribution of the source changes. The range variant (rANS) is suitable for dynamic use, but it is inferior in compression performance. This paper aims at overcoming these drawbacks, and proposes an intermediate variation between them. The proposed variation is based on rANS, and is derived via a randomized technique. Its performance is empirically evaluated. |
