Patent ID: 7639803

Claim:
An optical disk player to reproduce information recorded on an optical disk, being operable by a remote controller comprising a system controller, which includes: a remote controller image displaying unit to display an image of the remote controller on the display device by set-up; an inhibit key information storing unit to store 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 the side of the player or the optical disk; a user-designated inhibit key information storing unit to store 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; a color information storing unit to store different items of color information for discriminating the inhibit key information, the user-designated inhibit key information, and the inhibition-setting disabled key information from one another; an inhibition determining unit to determine whether or not the key entry is inhibited when it is received on a basis of presence/absence of the inhibit key information from the inhibit key information storing unit and/or the user-designated inhibit key information from the user-designated inhibit key information storing unit; an inhibition side determining unit to determine, if it is determined by the inhibition determining unit that the key entry is inhibited, on which side of the player or optical disk or of the user, the key entry is inhibited on a basis of the inhibit key information and user-designated inhibit key information; and a color mark displaying unit that reads, if a determination result by the inhibition side determining unit is the player or optical disk side, the color information corresponding to the inhibit key information from the color information storing unit thereby to display a general inhibit mark with a color represented by the color information at the segment of the corresponding key of the remote controller image displayed on the display device, that reads, if the determination result by the inhibition side determining unit is the user side, the color information corresponding to the user-designated inhibit key information from color information storing unit thereby to display a user-designated inhibit mark with color represented by the color information on the display device, and that displays, if the inhibit key on the side of the player or optical disk is the same as that on the side of the user, the general inhibit mark at the segment of the corresponding key of the remote controller image displayed on the display device and reads color information corresponding to the inhibition setting disabled key information from the color information storing unit thereby to display an inhibition setting disabled mark with color represented by the color information at the segment of the corresponding key of the remote controller image displayed on the display device.
