Systems in which information can be retrieved from an encoded, laser readable disc

摘要

Systems which have an integrated unit that allows both television signals and information retrieved from an onboard information storage device to be presented in visual, audio, or visual/audio form via output devices such as television screens and audio speakers. The operating mode-television or stored information retrieval and display-is selected by the user. The user is coached through steps leading to retrieval and presentation of the wanted information if the information retrieval mode is selected. A novel remote control allows the system user to choose the mode of operation and to navigate the steps needed to reach the wanted information from a location convenient to the user.
