Claim 10:
11. The H.265 encoding device according to claim 1, wherein
the precise comparison module comprises a distribution module, a plurality of hierarchical calculation modules, and a plurality of hierarchical comparison modules, the distribution module is coupled with the coarse selection module, and the hierarchical comparison modules are coupled with the distribution module, wherein
the distribution module is configured to distribute each CU block in each partition mode and the prediction information corresponding to the CU block to different hierarchical calculation modules according to each partition mode of each CTU block,
the hierarchical calculation module is used to calculate a plurality of cost information by performing intra-layer comparison according to the received CU block and the prediction information corresponding to the CU block, and select a prediction mode and a partition mode with the lowest cost corresponding to the CU block, and
the hierarchical comparison modules are configured to compare the prediction modes and costs corresponding to the partition modes selected by the hierarchical calculation modules of different layers, and select the partition mode with the lowest cost for the CTU block and the corresponding coding information.
