Abstract: A method of and apparatus for regulating color in a color broadcasting receiver is disclosed and is composed of a tuner, a demodulator, and a burst level detector for detecting the color burst level of a video signal output from the demodulator and outputting the color burst level as a corresponding control voltage signal. A color controller is disclosed for controlling the color by emphasizing or attenuating the high band components of the video signal output from the demodulator in accordance with the control voltage level from the burst level detector, so that it is possible to receive video signals without much change in color regardless of the variation of the voltage standing wave ratio (VSWR) that varies according to changes in the connection between the broadcast antenna and RF cable.

Abstract: A video display system is provided which compensates for video processing delays in multiple, inter-coupled video processing subsystems. The video display system is comprised of multiple video processing subsystems, each having a video bus for coupling video data between individual ones of the multiple subsystems. Each subsystem is adapted to receive one or more video data inputs and to selectively and programmably process the one or more video data inputs to provide a video data output. Each subsystem is comprised of a video delay subsystem coupled to an external video source and to the video bus. The video delay subsystem adds a programmable time delay to its respective external video source input data prior to coupling it to its respective processor for processing of video data contained within that respective video processing subsystem.

Abstract: A wireless local television transmission system with related methods, apparatus, and components. There is a source of a video signal to be viewed at a remote location such as a TV camera, cable select box, antenna, or VCR. An up converter is connected to the source for shifting the video signal to a frequency above the normal television bands. A transmitter is connected to the up converter for transmitting the video signal at the shifted frequency. A receiver is disposed at the remote location for receiving the transmitted video signal. A down converter is connected to the receiver for shifting the video signal back down to a frequency within the normal television bands and identified with a known channel. Finally, conventional television set functions are connected to the down converter for processing and displaying the video signal on the known channel.

Abstract: A video system includes a scan converter for developing a progressively scanned display of video lines from a two field interlaced line system. A spatial array of six pixels convering two successive video lines is developed and gradients are determined between diagonally opposed pairs of pixels and a vertically opposed pair of pixels in the array. The interpolated pixel is developed by averaging the two pixels in the smallest of the gradients. A non-orthogonal display is developed by using horizontally interpolated pixels in the array developed by averaging successive pairs of real pixels, which introduces an offset of one-half pixel duration to the interpolated pixels. An adaptive peaking and noise coring circuit is included. Another spatial array of three line of pixels, both real and interpolated, is developed and a horizontal, a vertical and two diagonal gradients between pairs of pixels in the array are calculated.

Abstract: A computer based video/graphics display system includes a computer system (22) having a graphics generator (24). A video signal from a video source (28) is fed through an input stage (26) to an asynchronous converter (30). The converter (30) synchronises the video signal to the graphics generator (24). The output from the asynchronous converter (30) and the output from the graphics generator (24) are fed to a fading/mixing matrix (34). The combined signal output from the fading/mixing matrix is fed to a computer display monitor (14). The system allows the mixing or windowing of computer graphics and a video image on a common display.

Abstract: A complex television system is provided for accommodating at the same time both highly technically oriented and less technically oriented users of the system. The system includes a state of the art complex television, a complex remote control transmitter device for use by the technically oriented user in both programming and, if desired, controlling the television, and a simple auxiliary remote control transmitter device for the less technically oriented user. The simple auxiliary remote control transmitter device has a minimum of keys, such as power-on, channel-up, channel-down, volume-up, and volume-down, as well as a switch which identifies the user. Different power-on and channel-up and down codes for each switch position is provided by the simple auxiliary remote control transmitter device, and each such code is different than the corresponding codes of the complex remote control transmitter device. In this manner, a microprocessor in the television will recognize which user is in control.

Abstract: In a charge-coupled imager in which an electronic shutter is controlled by varying an effective charge accumulating time of a charge-coupled device, according to this invention, the accumulation is started in synchronism with the trigger signal applied from the outside, the charge is accumulated only during a period of time determined by the shutter speed setting signal, and the accumulated charge is read out, whereby the charge accumulating time (exposure time) can be varied in such a manner that the starting of exposure time is made constant while its ending is varied. Therefore, the charge-coupled imager of inter-line transfer type of the invention can be made inexpensive and applied to a video processing apparatus such as a so-called machine-vision in which man's visual sense is not assumed.
