Patent number: 11956434Abstract: An encoder includes circuitry and memory coupled to the circuitry. The circuitry, in operation, for each coefficient of a plurality of coefficients included in a block, determines a base level relating to Context-Based Adaptive Binary Arithmetic Coding (CABAC) for the coefficient, and encodes an absolute value of the coefficient. In determining the base level, when one or more flags are used in encoding the absolute value of the coefficient, the base level is determined to be a first value, and when one or more flags are not used in the encoding, the base level is determined to be a second value that is smaller than the first value. In encoding the absolute value of the coefficient, when one or more flags are not used, a rice parameter is determined based on the base level which is equal to the second value, and the coefficient is binarized using the rice parameter.Type: GrantFiled: December 6, 2022Date of Patent: April 9, 2024Assignee: PANASONIC INTELLECTUAL PROPERTY CORPORATION OF AMERICAInventors: Yusuke Kato, Kiyofumi Abe, Takahiro Nishi, Tadamasa Toma
