A video wall has a plurality of spatial object image display devices, each spatial object image display device including a luminous display screen for providing a first image. The luminous display screen is operably engaged with a video wall computer, which is operatively engaged with at least one video input device such as a video cassette recorder (VCR). The video wall computer acts as a splitter to distribute the output of the VCR to the plurality of spatial object image display devices. Each...

An MPEG video decompression method and apparatus utilizing a plurality of stages interconnected by a two-wire interface arranged as a pipeline processing machine. Control tokens and DATA Tokens pass over the single two-wire interface for carrying both control and data in token format. A token decode circuit is positioned in certain of the stages for recognizing certain of the tokens as control tokens pertinent to that stage and for passing unrecognized control tokens along the pipeline. Reconfig...

A closed circuit video surveillance system having a plurality of camera stations which may be connected by entirely random and independent selection to a plurality of monitors located at different viewing stations without degradation of video quality. Each camera feeds its video signal over its own transmission line to a central switching station at which all camera signals are collected. Each viewing station has a monitor connected by a transmission line to an electromechanical switching means ...

A fluoroescence spectrometer or fluorometer for simultaneously presenting the excitation and emission spectra of a multicomponent sample in the form of an intensity matrix is disclosed which comprises an elongated cuvette for holding the fluoroescent sample, along whose length a spatially distributed spectrum of exciting energies is simultaneously directed, and a polychromatic analyzer which simultaneously analyzes the excitation and emission spectra given off by the sample along its length by p...

A video telephone (1) includes a communication block (2) having a telephone communication function and a display block (3) assembled so as to be mounted on the communication block (2) and having a television function. The display block (3) includes a display screen (4) and a television camera. The display block (3) can be adjusted in tilt with respect to the communication block (2).

A system of shortening transition time of transitions occurring in video signals is disclosed which includes circuitry for multiplying a function of the full wave rectified first differential of the input video signal by a function of the second differential of the input video signal and then adding the waveform resulting from such a product to the properly delayed input signal to provide a crispened output video signal. The system may be provided to crispen the luminance and chroma signals of a...

A method and device for selectively displaying a magnified image which permits an operator to appreciate the magnified image in its original context. The device includes a main monitor, a magnifier monitor, associated memories, and a controller. The magnifier monitor is movably mounted with respect to the main monitor. The position of the magnifier monitor in two dimensions represents the approximate center of a region on the main monitor to be magnified. The magnifier monitor is movable in a th...

A video encoding apparatus is provided with a resolution converting section, an encoding section, and a transmitting section. The resolution converting section enlarges or reduces a binary picture which represents the shape of an object. The encoding section encodes a binary picture reduced by the resolution converting section. The reduction ratio used by the resolution converting section is encoded, and the transmitting section transmits this encoded reduction ratio along with encoded data on t...

A terminal assembly for a personal computer integrates an S-video and a composite video terminal into a single socket on an electronic device. The socket includes inlets for separately carrying S-video and composite video signals. The socket can be connected to provide an S-video signal to another device using a standard S-video cable. Alternatively, the socket can be connected to provide a composite video signal using an adaptor that has two terminals: one for mating with the socket and couplin...

A video output controller has a video output buffer, a DMA controller, and a display controller. The display controller has a DMA command list processor configured to determine which of the DMA commands contained in the DMA command list must be issued, an initialize signal port configured to receive an initialize signal for starting initialization, a step signal port configured to receive a step signal for starting the issuance of the DMA command, and an external signal processor configured to p...
