ABSTRACT:
Systems which have an integrated unit (or module) that allows information retrieved from an onboard information storage device to be presented in visual, audio, or visual audio form via output devices such as CRT screens and audio speakers. When the system is turned on, the disc player is checked to see if a disc has been loaded. If a disc is found, a message identifying the type of disc that has been loaded and a message prompting the user to activate a control which will cause the disc to be played are displayed on the integrated unit screen. If a disc is not found, the system user is prompted to load a disc. Once this is done and the disc is detected, the step of ascertaining the type of disc, displaying a disc type message, and prompting the user to start the disc playing are carried out.
