    摘要： The present invention provides for a software routine executable by an image display system that controls at least one video timing signal (for example, the pixel clock signal) supplied to a display subsystem. More specifically, the software routine, adjusts the video timing signal in response to detection that the system is switching between power modes. The software routine preferably updates the video timing signal such that the system conserves power in response to detection that the system is switching from AC-powered operation to limited DC-powered operation.

    摘要： A method is provided for rendering display blocks on a video display device of a computer processing system having an existing display driver. The method includes the step of assigning each of a plurality of n video adapters to an mth display subregion of the display device. A call to a draw function of the existing display driver is received. The draw function corresponds to a particular shape to be drawn and includes starting and ending coordinates. The mth display subregion that drawing of the shape is to begin on is calculated from the starting coordinates. A function of the existing display driver is called by calling an address stored in the filter driver of a routine corresponding to the called function. The called function corresponds to the received draw function. A segment of the shape is rendered on the calculated mth display subregion by the nth display adapter corresponding thereto. A traversal is made to the nth video adapter corresponding to a next segment of the shape. The next segment of the shape is rendered on the mth display subregion corresponding to the traversed nth video adapter. The traversal and second rendering step are repeated until all segments of the shape have been rendered.

    摘要： Allows a video broadcast viewer to pause at anytime while viewing a program, and upon returning to be able to view the intervening segment. The video received during the pause period is stored and available for recall upon user command. The storage medium is circular in so much that the memory, upon becoming filled to capacity continues to write incoming information data over the previously stored data. The storage circuits employs a sequential access storage device and/or a direct access storage device. The storage circuit has a high speed memory input buffer and a high speed memory output buffer to account for the relatively long READ and WRITE access times of the storage device employed. At the end of the pause period, the user can view the stored video. The user has a choice between catching up to the regular broadcast or watching the remaining program video in a delay mode. The stored video may be viewed intermittently or continuously in regular, slow or fast motion, under user direct or remote VCR-type of video function control.
