Claim 19:
20. A method of operating an image processing apparatus, the method comprising:
extracting an input stream and parameter information by demultiplexing an input stream received from an encoding device by a demultiplexing processor;
storing the extracted input stream by an input stream buffer;
generating a restored frame by decoding the stored input stream by a decoding processor;
storing the generated restored frame by a restored frame buffer;
generating an output frame with an improved image quality by applying the extracted parameter information to the restored frame by a machine learning image quality improvement processor; and
storing the generated output frame by an output frame buffer,
wherein the encoding device updates a parameter by machine learning based on an error between an input original frame and a restored frame restored from the original frame, the restored frame decoded at a local decoder and stored at the restored frame buffer, and transmits the parameter information corresponding to the updated parameter together with the input stream.
