发明名称 Computer memory back-up
摘要 The interface apparatus couples a video recording device to the parallel data channel of a computer system and also to the computer video output circuitry, so that both digital information (such as computer programs or data files) and analog information (such as video signals for displaying on a TV monitor) may be stored on the same video recording medium. The apparatus thus permits storage of both digital information and human readable information in convenient back-to-back relationship. The interface also permits the computer video monitor to directly display stored or live video broadcasts, without computer intervention. The invention thus allows the display of graphic, photographic and motion picture information in analog format, thereby eliminating information loss through digitizing. An automatic search mode of the invention permits the computer to direct the video recording device to search for a predetermined location on the recording medium at high speed without human intervention.
