A coding system includes an inter prediction block (320), a transform and quantization block (334, 336), an encoding unit (380), and a reconstruction loop with an adaptive restoration block (360). The inter prediction block (320) performs prediction on a current frame, the transform and quantization block (334, 336) performs transform and quantization processes on prediction residues, and the reconstruction loop reconstructs the current frame to generate the restored reconstructed samples. The adaptive restoration block (360) performs restoration on processed data by considering a plurality of candidate restoration methods, selects one of the candidate restoration methods as a final restoration method, and generates adaptive restoration information corresponding to the final restoration method. The encoding unit (380) encodes the prediction information and adaptive restoration information to generate an encoded bitstream. |
