Claim 14:
15. An apparatus for processing video data comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:
maintain one or more tables wherein each table includes motion candidates;
determine that a first video unit of a video is a sharing node wherein child blocks coded with a specific mode under the first video unit are processed in parallel;
derive motion information for a first child block under the first video unit;
perform a conversion between a bitstream of the video and the first child block using the derived motion information; and
determine, whether to update the one or more tables using the derived motion information for the first child block,
wherein in a case that the specific mode is an inter advanced motion vector prediction (AMVP) mode and the sharing node is an inter AMVP sharing node, a process to update the one or more table using the motion information of the first child block under the sharing node is disabled, wherein the first child block is coded with the inter AMVP mode, and
wherein in a case that the specific mode is an intra block copy (IBC) AMVP mode and the sharing node is an IBC AMVP sharing node, the process to update the one or more table using the motion information of the first child block under the sharing node is disabled wherein the first child block is coded with the IBC AMVP mode.
