Classification: CPC H | IPC H

Claim 14:
15. An apparatus for data decoding, the apparatus comprising:
at least one memory configured to store computer program code; and
at least one processor configured to access said computer program code and operate as instructed by said computer program code, said computer program code including:
first obtaining code configured to cause the at least one processor to obtain coded data corresponding to a current to-be-decoded unit;
second obtaining code configured to cause the at least one processor to obtain a syntax indicating a 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;
determining code configured to cause the at least one processor 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;
selecting code configured to cause the at least one processor to select a target coding mode from the candidate coding mode set; and
decoding code configured to cause the at least one processor to decode the current to-be-decoded unit according to the target coding mode, thereby obtaining corresponding decoded data.
