Abstract
A method of coding video data is provided to include resetting one or more tables including motion candidates before coding video blocks that are in a first video region of a picture in a video; coding a video block in the first video region, and determining whether to update the one or more tables using motion information derived for the video block; deriving motion information for a subsequent video block to the video block in the first video region; and coding the subsequent video block using the motion information derived for the subsequent video block; wherein one or more candidates from the one or more table are selectively checked during a motion candidate list construction process which is used to derive the motion information for the subsequent video block.
