    Abstract: An encoding includes: obtaining, by an encoder, data to be encoded, where the data to be encoded is at least one LCU; determining, a quantization depth parameter of the LCU according to a preset bit rate control algorithm, and adding the quantization depth parameter into the data to be encoded; determining, a QP of each CU according to a size of a minimum picture block and a size of each CU included in the LCU; calculating, by the encoder, a QP difference of each CU according to the QP of each CU and a QP prediction value of each CU; for each CU that satisfies a preset condition, carrying, by the encoder, the QP difference of the CU in the CU; and encoding, by the encoder, the quantization depth parameter, the QP difference of the CU that satisfies the preset condition, and each CU to obtain a bit stream.

    Abstract translation: 编码包括:由编码器获取待编码的数据,其中要被编码的数据是至少一个LCU; 根据预设比特率控制算法确定LCU的量化深度参数,并将量化深度参数加到待编码的数据中; 根据最小图像块的大小和包括在所述LCU中的每个CU的大小来确定每个CU的QP; 根据每个CU的QP和每个CU的QP预测值,由编码器计算每个CU的QP差; 对于满足预设条件的每个CU,由编码器携带CU中的CU的QP差; 并且由编码器编码量化深度参数,满足预置条件的CU的QP差和每个CU以获得比特流。
