Apparatus and method for decoding video data

The invention provides a method for decoding video data by electronic equipment. The electronic device determines, according to the video data, at least one block vector predictor for a block unit determined from the current frame. The electronic device determines, from the current frame, a block template region adjacent to the block unit and a plurality of candidate template regions, each candidate template region indicated by a particular block vector predictor of the at least one block vector predictor and a corresponding one of a plurality of block vector differences in the vector difference list. The electronic device determines a first cost value between the block template region and each candidate template region, and determines an adjusted difference list including at least one block vector difference based on the first cost value. The electronic device selects a reference block from the current frame to reconstruct the block unit based on the adjusted difference list. 本发明提供了一种电子设备解码视频数据的方法。电子设备根据视频数据
