Abstract: A digital video display system wherein the various characters to be displayed are displayed in the form of images of the complete character rather than the standard dot-matrix pattern of the prior art. A character generator in the display system stores signals representing the various characters to be displayed which are retrieved from storage in response to a character code. The signals are in the form of a binary code having a sufficient number of bits to represent a different number of levels of gray-scale or luminance values for the various picture elements making up the character image. The binary codes thus retrieved from storage are supplied to a video synthesizer that generates the video signal to display the character images which may be displayed in a number of different modes including white-on-black, black-on-white, black-on-gray, and white-on-gray as well as different combinations of such modes to represent a cursor.

Abstract: This disclosure relates to a color video system that is adapted to receive digital codes representing values of different colors that are to be displayed to create an image on a standard video monitor. The system employs a video synthesizer which includes a memory in which appropriate digital signals are stored representing the desired transformations of the signals to signals that are to be transmitted to the video monitor. Specifically, the system is adapted to transform respective color codes to codes required for the I, Q, and Y mode of transmission.

Abstract: This disclosure relates to a digital video display system wherein a control element is provided that includes position and count registers to specify the initial position of a scan line and the number of scan lines displayed which registers are supplied with incoming data to specify the position of each character line so that the position of a character image on display can be adjusted upwardly or downwardly to give the appearance of smooth scrolling.The various characters to be displayed are displayed in the form of images of the complete character rather than the standard dot-matrix pattern of the prior art. A character generator in the display system stores signals representing the various characters to be displayed which are retrieved from storage in response to a character code. The signals are in the form of a binary code having a sufficient number of bits to represent a different number of levels of gray-scale or luminance values for the various picture elements making up the character image.
