Assignee: APPLE INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. One or more non-transitory computer readable media storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
encoding a current block according to an intra block copy (IBC) mode, wherein encoding the current block according to the IBC mode comprises:
constructing an IBC merge candidate list for the current block;
deriving a block vector of the current block;
obtaining a prediction sample of the current block based on the block vector;
encoding index information indicating one of the IBC merge candidates identical to the block vector of the current block; and
determining whether to update an IBC motion information table based on the block vector of the current block, wherein when a size of the current block is smaller than a threshold size, the IBC motion information table is not updated based on the block vector of the current block,
wherein the IBC merge candidate list includes an IBC merge candidate derived based on the IBC motion information table,
wherein the IBC motion information table includes an IBC motion information candidate derived from a block to which an IBC mode is applied before the current block, and
wherein a maximum number of the IBC merge candidates that the IBC merge candidate list may include is determined based on information signaled via a sequence parameter set.
