Claim 4:
5. The H.265 encoding apparatus according to claim 1, wherein
the coarse selection module comprises an inter-prediction module and an intra-prediction module, the inter-prediction module is coupled with the preprocessing module and the precise comparison module, and the intra-prediction module is coupled with the preprocessing module and the precise comparison module,
wherein
the inter-prediction module is configured to perform inter-prediction on each PU block of the CTU block in each partition mode, select one or more PU blocks with reference information obtained from the reference frame and having cost less than a preset cost value, and determine a motion vector of the selected reference PU blocks as the prediction information corresponding to the partition mode;
the intra-prediction module is configured to perform intra-prediction on each PU block in each partition mode, and select one or more intra-frame prediction directions whose cost is less than a preset cost value relative to each PU block, wherein the selected intra prediction direction is used as the prediction information corresponding to the partition mode.
