ABSTRACT:
An optical disk player to reproduce information recorded on an optical disk, being operable by a remote controller, includes a system controller. The system controller displays an image of the remote controller on a display device by set-up. The system controller stores different items of color information for discriminating, from one another, inhibit key information indicating a key by which key entry is inhibited during playing, the key being other than keys for which inhibition setting of a key operation is previously disabled on a side of the player or the optical disk, user-designated inhibit key information indicating a user-designated key for which inhibition of the key entry is desired during playing of the optical disk, and inhibition-setting disabled key information. The system controller displays color marks according to the different items of color information at segments of corresponding keys on the remote controller image displayed on the display device.
