9 Hage First, FIG. 2 shows a sketch of the title display remote control system of the present invention, in which an optical disc is loaded into the optical disc playback device 22 and played back. Next, information such as the number of songs, total play time, and play start time of each song on this optical disc (this is called TOC information) is read from the Toe information area and sent to the optical transmitter 2.
7 to transmit the Toe information to the wireless remote control device 23. To explain using FIG. 1, the TOC information reproduced by the optical disc reproduction device 1o is converted into an optical signal using the transmitting/receiving microprocessor 11 and the optical transmitter 13, and is transmitted to the wireless remote control device 21. Ru. The transmitted optical signal is converted into an electrical signal by the light receiving device 19, and the system microprocessor 2o searches the removable nonvolatile storage device 17 for the same information as the input TOE information, and stores the same TOC information. If there is no T
The OC information is stored in the removable nonvolatile storage device 17. Next, using the input device 15 and display device 10-7, the title of the loaded optical disc and the title of the song recorded on the optical disc are entered in characters. Then, the input optical disc title and song title are stored in the removable nonvolatile storage device 17 through the system microprocessor 2o. Next, after loading other optical discs, the disc title and song title are input and stored in the removable nonvolatile storage device 17. Thereafter, the optical disc is removed from the optical disc reproducing device 14, and the power to the entire system is turned off. Then, when the power is turned on and the same optical disc as described above is loaded into the optical disc playback device, the optical disc playback device 10
The TOC information reproduced is converted into an optical signal by the transmitting/receiving microprocessor 11 and the optical transmitter 13, and is transmitted to the wireless control device 21. The transmitted optical signal is converted into an electrical signal by the light receiving device 19, and the system microprocessor 20 converts the input TOC information and the same TOC information into the input signal.

A search is made to see if it exists in the wearable non-volatile storage device 17.

Then, if there is the same ToC information that was input last time, the corresponding optical disc title and song title information that was input into the removable non-volatile storage device 17 following the input of the previous TCI information are read out and read out all at once. It is displayed on the display device 16.

A flowchart showing the above contents is shown in FIG. Then, the title information of the displayed song, for example, as shown in FIG. The optical disc reproducing device 14 is controlled by transmitting command information.

As described above, according to this embodiment, an optical disc playback device is provided with an optical transmitter and a light receiver to enable transmission of Toe information and reception of command information, and a conventional wireless remote control device receives TOC information. By providing a permanent light receiving device and a removable non-volatile storage device for storing ToC information and title information, when the same disc is played again, the disc is recognized based on the disc's ToC information and the disc of that disc is Titles and song titles can be automatically displayed all at once. That is, when an optical disc that is the same as the optical disc stored in the nonvolatile storage device is loaded, the identity of the disc is determined based on the TOC information, and the title and song title of the optical disc are determined based on the TOC information. can be displayed all at once, making it very easy to use. Best of all, if the storage capacity of the removable non-volatile storage device is exceeded, it can be replaced with a new non-volatile storage device.

Note that although light is used as the wireless signal in the above embodiment, other methods such as ultrasonic waves or radio waves may also be used.

Effects of the Invention As described above, the present invention provides a conventional optical disc playback device with an optical transmitter for transmitting TOC information, and a conventional wireless control device with a light receiving device and a removable nonvolatile storage device. It is now possible to automatically display disc titles and song titles on the display device of the wireless remote control device at hand, improving visibility and operability. Furthermore, even if the storage capacity of the nonvolatile storage device is exceeded, it can be replaced with a new nonvolatile storage device, so there is no limit to the storage capacity. In addition, since the stored non-volatile storage device can be used for other same wireless remote control devices, the saved non-volatile storage device is also useful for information exchange.
