Abstract:
Devices, systems and methods for coding video using one or more tables to store motion information and processing subsequent blocks are described. In one aspect, a video coding method is provided to include deriving motion information for a first video block, wherein one or more candidates of one or more tables are selectively checked during a motion candidate list construction process which is used to derive the motion information for the first video block, wherein each table of the one or more tables includes motion candidates derived from previously coded video blocks that are coded prior to the first video block; and coding, based on the motion information, the first video block.
