摘要： 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. The video synthesizer can generate output voltage levels in discrete steps for the different luminances to be employed. The voltage output signals differ from level to level in accordance with the 2.2 root of luminance.

摘要： 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.
摘要翻译：本公开涉及一种彩色视频系统，其适于接收表示将被显示以在标准视频监视器上创建图像的不同颜色的值的数字代码。该系统采用视频合成器，其包括存储器，其中存储适当的数字信号，表示将要发送到视频监视器的信号的信号的期望变换。具体地，该系统适于将各个颜色代码转换为I，Q和Y传输模式所需的代码。

摘要： 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.
