摘要： Graphical user interface system and methods for providing "hints" for screen objects of interest, particularly user interface elements which rely upon multitudes of iconic (bitmap image) indicia. The interface includes a static (status) frame or window positioned in a non-intrusive fashion below or to one side of a client area (active portion) of a user interface. The frame is continually updated with appropriate descriptors or "hints" (e.g., text and/or graphics) as a screen cursor moves from one screen object to another.

摘要： To minimize the capacity of a random access memory for storing display data of a display controller for displaying characters or the like on a television screen, the display data is divided into the data for characters or the like and the blank data free from characters with a discriminator, the data for characters or the like are stored in the random access memory every unit address, the number of non-characters shown by the blank data is counted by a counter, and the cumulative counted number is stored in the unit address of the random access memory. When the blank data is displayed, the counted number is read from the random access memory and non-character signals equivalent to the counted number are output to a display unit.

摘要： In a videotex terminal system, image data has a code frame and a photo frame, and each of these frames includes dot pattern data, foreground color data, background color data, and flashing data. This type of image data can be simultaneously displayed on both a cathode ray tube display (CRT) and a liquid crystal display (LCD). These two displays are not controlled independently of each other; rather, they are controlled in association with each other by a display control unit to eliminate the need to use a complicated software program in a central processing unit (CPU) and to reduce the number of hardware components required by the system. The display control unit is particularly advantageous in that is can easily discriminate the code frame and the photo frame from each other, and it enables the system to execute a reliable display operation.

摘要： A television receiver for displaying a video signal representing a first frame with a first aspect ratio is described wherein the video signal includes a coded character signal to be reproduced within the first frame. The receiver includes: a decoding unit for decoding the coded character signal; a first converter for converting the video signal into a second video signal to be reproduced to have a second frame with a second aspect ratio in accordance with a mode signal; a second converter for converting the decoded character signal into a second character signal to be reproduced to have a third frame smaller than the second frame; and a displaying unit for displaying the second video signal and the second character signal with characters from the second character signal being superimposed on a video image reproduced from the second video signal. The second converter controls start position and size of displayed characters by controlling counters used for determining the start position and size. Alternatively, a frequency of a clock signal used for determining the start position and size may be controlled.

摘要： A method and circuit (30) for providing drive signals that have a half-tone and fast blanking capability to a video display (20) has a video preamplifier (31) integrated on a semiconductor substrate (35) for receiving an input video signal (14) and for producing an output drive signal (17) to the video display (20). The preamplifier (31) may have a plurality of channels (31', 31") corresponding to each color video signal to be processed. A halftone control circuit (21), also integrated on the semiconductor substrate (35) receives halftone control signals (60) and connected to reduce the drive signal produced by the video preamplifier (31). A fast blanking circuit (22) for receiving fast blanking control signals (80) is also integrated on the semiconductor substrate (35) and is connected to substantially turn off the drive signal produced by the video preamplifier (31). The preamplifier (31) is constructed with bipolar transistors and the halftone and fast blanking control circuits are constructed with MOS transistors, for example by a LinBiCMOS semiconductor manufacturing process. The preamplifier (31) may include a plurality of amplification stages, (40, 43-45, 48, 50) wherein the halftone control circuit (21) and the fast blanking control circuits (22) control a drive level prior to a last amplification stage (50) to enable low level control of the halftone and fast blanking operations.

摘要： A VGA controller having an overlay mode for displaying images formed from selective components of multiple image planes. A first image and a second image overlaying the first image are interleaved into three of four bit planes of a dynamic random access memory. When displaying the image, the controller will simultaneously read from the first and second images. If the value of the second image is non-zero, then the second image is displayed. Otherwise, the first image is displayed.
