Zusammenfassung:An example apparatus for binarizing video data includes a memory configured to store video data; and one or more processors implemented in the circuit and configured to: calculate a local sum value (locSumAbs value) of absolute values of coefficients adjacent to a current coefficient of a current block of video data; deriving a shift value from the locSumAbs value, and deriving a shift value from the locSumAbs value; using a shift value to normalize the locSumAbs value, and using the shift value to normalize the locSumAbs value; the rice parameter is determined by using the normalized locSumAbs value, and the rice parameter is determined by using the normalized locSumAbs value; and binarizing or inversely binarizing the current coefficient by using the Rice parameter. In this manner, these techniques may allow for a more suitable Rice parameter value selection when binarizing high bit depth data in conjunction with performing context adaptive binary arithmetic coding (CABAC). 一种用于二进制化视频数据的示例设备包括:被配置为存储视频数据的存储
