VIQ Computer graphics system

Abstract: A YIQ computer graphics system includes a data processing system having a data tablet for receiving inputs from an artist and a video processing system connected to the data processing system. The video processing system includes a two component expandable frame store with the first component storing video intensity information for each pixel of a visual image and with the second component storing two video color components each for one-half of the visual image. The video processing system further includes a memory controller coupled to receive pixel address information identifying pixel locations within a row and column matrix of pixel locations containing the visual image and addressing specific locations within the frame store in response thereto, an interface circuit coupled to transfer video data between the frame store and the data processing system at pixel locations within a matrix of locations defined by the data processing system, and a video output processor coupled to provide matrix address locations to the frame store and receive in return video data from the frame store to generate a color video output signal in raster scan order. The video processing system may also include an input scanner coupled to write into the frame store video information on a continuous frame-by-frame basis to permit the video output processor to output a video signal which indicates a continuously changing video image on a frame-by-frame real time basis.

Sync generator, video processor

Abstract: A single compact multi-function video processing unit of a color video system has a sync generator for driving a video source and a video processor for providing video functions. A bus system interconnects the sync generator and video processor.

Method for the acoustic design of video games

Abstract: The invention relates to a method for the audio design of video games which are depicted by means of combining a video game device with a monitor device, usually a television set. It is the object of the invention to improve the previously simple audio accompaniment and to design and play back the audio information in such a way that the user of a video game device is addressed not only visually, but also acoustically by the programmed events of the video game. The audio information accompanying the respective game can be called up in the video game device and stored using the frequency response and phase relations characteristic of artificial head stereophonics. The play back of said information takes place via at least one set of stereo headphones.

Video disk player simulator, method and apparatus

Abstract: A system and method for simulating the operation of a video disk player playing an interactive video disk, which comprises a video tape player, a timing code reader, a monitor, a computer, and an input device. A control program is entered into the computer through the input device. A video tape is loaded in the video tape player. The video tape player generates video signals and a timing code signal associated therewith. The video signals are displayed on the monitor. The timing code signal is converted into an output signal by the timing code reader. The computer, under operator control, controls the operation of the video tape player, in response to the output signal and the control program such that the video signals displayed on the monitor simulate the operation of a video disk player playing an interactive video disk.

Copying-protected prerecorded video cassette and method and coder for producing and method and decoder for playing such a video cassette

Abstract: On the magnetic tape of a video cassette, the video signals are stored distorted or modified for copying protection. Furthermore, a coding associated with the video cassette is provided on the magnetic tape. When the video cassette is played, the correspondence of the coding existing on the magnetic tape with a coding which is applied to a code carrier belonging to the video cassette is compared. On agreement, a circuit arrangement is activated by means of which the distortion or modification of the video signals is cancelled.
