Claim 0:
1. A video coding method, comprising:
deriving motion information for a first video block which is coded using an intra block copy (IBC) mode, wherein one or more motion candidates of one or more tables are selectively checked in an order 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 coded with the IBC mode, and arrangement of the motion candidates in the table is based on a sequence of addition of the motion candidates into the table;
coding, based on the motion information, the first video block;
adding, in a case of a size of the first video block satisfying a predefined condition and the first video block being coded with the IBC mode, a new motion candidate related to the motion information of the first video block into the one or more tables, wherein at least one motion candidate in the table is deleted when the table is full before the new motion candidate is added to the table, and not adding, in a case of the size of the first video block not satisfying the predefined condition or the first video block not being coded with the IBC mode, the new motion candidate related to the motion information of the first video block into the one or more tables,
wherein the new motion candidate has a maximum index in the table.
