Classification: CPC G  H | IPC G

Claim 20:
21. The apparatus according to claim 20, wherein when a first residual coding flag value of the first target frame is not equal to a second residual coding flag value of a previous frame of the first target frame, the residual coding switching flag value indicates that the first target frame is a switching frame;
when the first residual coding flag value is not equal to the second residual coding flag value, and a modification flag value of the second residual coding flag indicates that the second residual coding flag value has not been modified, the residual coding switching flag value indicates that the first target frame is a switching frame; or
when first residual coding flag value is not equal to the second residual coding flag value, and a residual second coding switching flag of the previous frame of the first target frame indicates that the previous frame of the first target frame is not a switching frame, the residual coding switching flag value indicates that the first target frame is a switching frame; wherein
the first residual coding flag value indicates whether a residual signal of the first target frame needs to be encoded, and the second residual coding flag value indicates whether a residual signal of the previous frame of the first target frame needs to be encoded.
