  • Automatic storage medium identifying method and device, automatic music CD identifying method and device, storage medium playback method and device, and storage medium as music CD
    Patent number: 6646966
    Abstract: A data reproducing unit reproduces data read by a first reading unit from a storage medium. A storage unit stores added information corresponding to data stored on the storage medium. The added information is read by the second reading unit and reproduced by an added information reproducing unit. A control unit controls such that the data is reproduced by the data reproducing unit in synchronism with the reproduction of the added information by the added information reproducing unit.

  • Storage medium playback system and method
    Patent number: 6283764
    Abstract: A first reading unit reads data stored in a second storage area of a storage medium (including reproduction management information), and stores it in another storage medium. A first reproducing unit reproduces the data read from a first storage area of a storage medium by the first reading unit. A second reading unit reads data stored by the first reading unit in another storage medium, and outputs it to a second reproducing unit. The second reproducing unit reproduces data received from the second reading unit. A controlling unit synchronizes the reproduction of the data by the first reproducing unit with the reproduction of the data by the second reproducing unit.

  • STORAGE MEDIUM PLAYBACK SYSTEM AND METHOD
    Publication number: 20010006771
    Abstract: A first reading unit reads data stored in a second storage area of a storage medium (including reproduction management information), and stores it in another storage medium. A first reproducing unit reproduces the data read from a first storage area of a storage medium by the first reading unit. A second reading unit reads data stored by the first reading unit in another storage medium, and outputs it to a second reproducing unit. The second reproducing unit reproduces data received from the second reading unit. A controlling unit synchronizes the reproduction of the data by the first reproducing unit with the reproduction of the data by the second reproducing unit.

  • Karaoke system for synchronizing and reproducing a performance data, and karaoke system configuration method
    Patent number: 5880388
    Abstract: A first reading unit reads first performance data from a first storage medium, and outputs it to a reproducing unit. A second reading unit reads second performance data from a second storage medium, and outputs it to the reproducing unit. The reproducing unit reproduces the first performance data inputted from the first reading unit, and the second performance data inputted from the second reading unit. A control unit synchronizes reproduction of the first performance data and reproduction of the second performance data, and switches between these reproductions.
