(EN) A method of block vector(BV)prediction for an IntraBC mode(Intra-block copy mode)coded block in a video coding system according to the present invention is disclosed. Multiple BV candidate lists are derived from neighboring blocks of the current block.A BV candidate list is selected as a BV predictor for the BV of the current block. The current block is coded based on an Intra reference block located according to the BV of the current block. In one embodiment,a left-bottom(LB) block of the current block is used to derive the first BV candidate list and an above-right(AR)block of the current block is used to derive the second BV candidate list. A 1-bit index code is signaled to select a BV predictor between the first BV candidate list and the second BV candidate list.
(ZH) 根据本发明，公开了一种用于视频编码系统中的块内复制模式编码块的块向量预测的方法。多个块向量候选列表从当前块的相邻块导出。选择块向量候选列表作为当前块的块向量的块向量预测值。基于根据当前块的块向量定位的帧内参考块来对当前块进行编码。在一个实施例中，当前块的左下块用于导出第一块向量候选列表，并且当前块的右上块用于导出第二块向量候选列表。用信号发送1比特位索引代码以在第一块向量候选列表和第二块向量候选列表之间选择块向量预测值。
