摘要：
This disclosure relates to adaptively reordering reference frames for video coding technologies. Template matching (TM) may be used to reorder the reference frames or reference frame pairs for each block by comparing the difference between the template of a current block and the template of a reference block with reference to the motion information of the spatial reference motion information (or spatial motion vectors) and/or temporal reference motion information (or temporal motion vectors). The difference between the template of current block and the template of the reference block may be calculated for each spatial reference motion information and/or temporal reference motion information, and marked as the score value of the associated reference frames or reference frame pairs. The available reference frames or reference frame pairs are ranked based on the score value.
