Encoding method and device, and decoding method and device |
摘要 |
An encoding method and device, a decoding method and device and an encoding/decoding system. The method comprises: an encoding end acquiring data to be encoded, the data to be encoded being at least one LCU; the encoding end determining a quantization depth parameter of the LCU according to a bit rate control algorithm, and writing the quantization depth parameter into the data to be encoded; the encoding end determining a QP of each CU according to the minimum picture block size and the size of each CU contained in the LCU; the encoding end calculating a QP difference of each CU according to the QP of each CU and a QP prediction value of each CU; for each CU satisfying a preset condition, the encoding end carrying the QP difference of the CU in the CU; the encoding end encoding the quantization depth parameter, the QP difference of the CU satisfying the preset condition, and each CU to acquire a bit stream. Further provided are a decoding method and an encoding/decoding device. |
