History-based candidate list with classification

Abstract:

Techniques are described for history-based candidate list operations in video coding for determining motion information for a current block. In one example, a device for decoding video data includes a memory configured to store a history-based candidate list and a video decoder. The video decoder is configured to construct the history-based candidate list by storing, in the memory, motion information of reconstructed blocks into the history-based candidate list as candidates of the history-based candidate list, identify a subset of candidates of the history-based candidate list, generate a candidate list based on the identified subset of candidates of the history-based candidate list, and reconstruct a current block based on the generated candidate list.
