In a teleconference terminal equipment; a picture codec for simultaneously displaying a still picture and video on a single screen, comprising an analog-to-digital converter which converts a picture signal into digital picture data, a picture-in-picture processor which is supplied with the digital picture data as self-picture data of the terminal equipment, a video decoder or a still picture decoder which decodes input picture data and delivers the decoded data to the P-in-P processor, and a digital-to-analog converter which is supplied with picture data for forming a P-in-P frame, having been produced from the self-picture data and the decoded data by the P-in-P processor, and which converts the supplied picture data into an analog signal and delivers the analog signal as an output.

Picture codec and teleconference terminal equipment

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.

The picture codec includes an analog-to-digital converter which converts a picture signal into digital picture data, a picture-in-picture processor which is supplied with the digital picture data as self-picture data of the terminal equipment, a video decoder or a still picture decoder which decodes input picture data and delivers the decoded data to the P-in-P processor, and a digital-to-analog converter which is supplied with picture data for forming a P-in-P frame, having been produced from the self-picture data and the decoded data by the P-in-P processor, and which converts the supplied picture data into an analog signal and delivers the analog signal as an output.

Picture codec for teleconference equipment, which forms and displays

A teleconference terminal equipment adapted to construct an AV meeting system as an intended use, comprising a network interface and communications network control unit, 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 unit and a communication frame received by the same, respectively, a picture codec which codes and decodes video data, a video input/output interface which connects an external camera to the picture codec, a camera control/external device multiconnector, and a CPU which controls an operation of the external camera through the multiconnector on the basis of control data delivered from the control unit.

Teleconference terminal equipment and teleconference module

A video telephone system which includes a master video telephone terminal (secretary terminal) connected to a communication network and slave video telephone terminals (executive terminals) connected to the master video telephone terminal in which the master video telephone terminal can transfer a call to the slave video telephone terminals. When a call comes into the secretary terminal from a remote terminal on the communication network, a line control section of the secretary terminal sets up a line. Video data and speech data received on the line are decoded by a video signal coding-decoding section and an aural signal coding-decoding section and the decoded signals are output through a display and a speech output device. Sound and images picked up by a microphone and a camera respectively are coded for transmission. Then, if a predetermined instruction of call transfer to an executive terminal is entered on an electronic tablet of the secretary terminal, a communication branch control section of the secretary terminal calls the executive terminal, sets up a line between the secretary and executive terminals on a local transmission network, and connects the line between the secretary terminal and the remote terminal.

Magnetic resonance imaging scanner

Central processor for an electronic computer

A housing for accomodating an electronic apparatus including heat-generating parts, in which the surface of a cooling air inlet port in the front or rear side of the housing is formed in arcuate fashion and recessed as viewed from the interior of the housing. As a result, the velocity of air introduced is remarkably reduced thereby improving the heat radiation of the housing.
