ABSTRACT:
A teleconference terminal equipment adapted to construct an AV meeting system as an intended use, comprising a network interface and communications control apparatus, a multimedia multiplexing/demultiplexing and interterminal signal control unit which multiplexes and demultiplexes video data and control data contained in a communication frame to be transmitted by the control apparatus and a communication frame received by the same, respectively, a video codec which codes and decodes motion picture data, a video input/output interface which connects an external camera to the video codec, a camera control/external device multiconnector, a CPU which controls an operation of the external camera through the multiconnector on the basis of control data delivered from the control unit, and a box-shaped housing with an adjustable supporter to house the communication control apparatus, video codec, and camera.
