Claim 19:
20. A non-transitory computer-readable storage medium storing computer instructions that, when executed by at least one processor of a device, cause the at least one processor to:
obtain coded data corresponding to a current to-be-decoded unit;
obtain a syntax indicating coding mode restriction type corresponding to the current to-be-decoded unit by decoding the coded data, the coding mode restriction type indicating which coding mode of the current to-be-decoded unit that decoding of the current to-be-decoded unit is restricted to;
determine a candidate coding mode set corresponding to the current to-be-decoded unit according to the coding mode restriction type, the candidate coding mode set comprising a block copy intra-frame coding mode;
select a target coding mode from the candidate coding mode set; and
decode the current to-be-decoded unit according to the target coding mode, thereby obtaining corresponding decoded data.
