Claim 18:
19. The H.265 encoding method according to claim 12, 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, the method further comprises:
distributing, by the distribution module, each CU block in each partition mode and the prediction information corresponding to the CU block to different hierarchical calculation modules;
calculating, by the hierarchical calculation modules, a plurality of cost information by performing intra-layer comparison, and selecting a prediction mode and a partition mode with the least cost corresponding to the CU block;
comparing, by the hierarchical calculation modules, the prediction modes and the costs corresponding to the partition modes selected by the hierarchical calculation modules of different layers, and selecting the partition mode with the lowest cost for the CTU block and the corresponding coding information.
