ENCODING METHOD, APPARATUS AND DEVICE AND DECODING METHOD

摘要

PURPOSE: An encoding apparatus for applying various encoding modes is provided to efficiently change an encoding mode and signal compression by using a general-purpose encoding method and a general-purpose encoding device. CONSTITUTION: A coding request estimation unit(11) estimates coding request values about one mode used for encoding an input frame signal. A mode determination unit(12) determines an encoding mode used for encoding an input frame signal according to a mode selection policy. An encoding unit(13) encodes an input framing signal by the use of the determined encoding mode.
