Terminal supporting signaling for MPEG-4 tranceiving

A terminal supporting the MPEG (MPEG) -4 signaling for transmission and reception is disclosed. And the terminal is provided with a system control unit for performing signaling for negotiating the capability of the audio codec, to multiplex the encoded data multiplexer, and a terminal for performing a video codec, an audio coding and decoding for performing a video coding and decoding, the the system control unit, and a plurality of parameters for determining video capability to be used to register, the parameters of one of the video capability registration unit to register parameters for determining video capability that corresponds to at least the level of the MPEG-4; And a plurality of parameters for determining audio capability to be used to register, in which the parameter is at least one of the audio capability registration unit to register parameters for determining audio capability for the MPEG-4 level in; And a plurality of parameters for determining a system's ability to be registered to be used, one of the parameters is at least MPEG-4 level, the parameters for determining a system's ability registered system capability registration unit for the; characterized in that it comprises a . The terminal may perform the signaling that supports MPEG-4 as the basis for applying MPEG-4 visual, audio, and system in the video conferencing system.
