Claim 9:
10. The method according to claim 9, 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 first 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 first residual coding switching flag value indicates that the first target frame is a switching frame; or
when the first residual coding flag value is not equal to the second residual coding flag value, and a second residual 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 first 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.
