CE-1.8: Results of Rice Parameter Derivation with Content Adaptation
Authors: K. Kawamura KDDI K. Unno KDDI Kei Kawamura
Abstract
This contribution reports a result of a rice parameter selection method in the CE. The proposed method focuses on the regular residual coding for operation range extensions of VVC. Since a distribution of residual coefficient values becomes wider for high bit depths and high through-put, the current rice parameter range makes a performance degradation. Such the distribution depends on not an internal bit depth but the content itself. To address this issue, this contribution decomposes the locSumAbs value into shift parameter and index parameter of the pre-defined look-up table.
