Abstract
Abstract A method of scrolling up or down on the face of a television type display device is described where frames are repetitively generated, and video information cyclically supplied by a storage device is displayed during each frame. The method involves selectively changing the cycle of the frames generated on the face of the cathode ray tube to commence at a home position or initial starting point at any selected storage location in the cyclical storage device. This is accomplished by the method steps of storing a home position character at any storage location in the cyclical storage device, initiating a new frame starting from the home position whenever the home position character is detected, and moving the home position character to different storage locations to scroll up or down.
