Claim 26:
27. An apparatus, comprising: one or more electronic circuits or processors configured to:
construct a history-based motion information candidate list, wherein the history-based motion information candidate list is an ordered list comprising N history-based motion information candidates Hk, k=0, . . . , N−1, the N history-based motion information candidates Hk containing motion information of N preceding blocks preceding a block, wherein N is an integer greater than 0, wherein each history-based motion information candidate comprises:
one or more motion vectors (MVs),
one or more reference picture indices corresponding to the MVs, and
an interpolation filter index;

add at least one history-based motion information candidate from the history-based motion information candidate list into a motion information candidate list for the block; and
derive motion information of the block based on the motion information candidate list, wherein the derived motion information of the block comprises:
i) one or more MVs,
ii) one or more reference picture indices corresponding to the MVs, and
iii) an interpolation filter index.
