Motion picture encoding method and apparatus

摘要

A motion picture encoding method and apparatus is disclosed, which adaptively switches filters in accordance with the property of a motion picture and the condition for encoding and to improve the encoding efficiency. A motion picture is encoded a plurality of times, an encoding parameter for encoding is optimized, the property of the motion picture signal is measured, and filtering is performed by using the encoding parameter or the property of the measured motion picture signal and thereby optimizing the filter characteristic only for the final-time encoding so as to practically generate and output an encoding signal (bit stream). $$
