Claim:
An optical disk player comprising: an optical pickup which reads out signals from an optical disc by irradiating a laser beam on the optical disk; a signal processor which processes the signals read out by the optical pickup; a decoder which decodes the signals processed by the signal processor; an HDMI (High-Definition Multimedia Interface) output terminal to which a monitor display device is connectable through an HDMI cable and outputs the signals decoded by the decoder to the monitor display device through the HDMI cable; a main controller which controls the optical pickup, the signal processor, and the decoder; and a remote controller which is operated by a user to input various commands to the main controller, wherein the main controller obtains information relating to resolutions that the monitor display device supports; the command for switching the resolution of the monitor display device is transmitted from the remote controller to the main controller when a specific key provided in the remote controller is operated by the user; when a command for switching the resolution of the monitor display device is inputted through the remote controller, the main controller converts video signals among the signals decoded by the decoder to have a resolution corresponding to the command and outputs the converted video signals to the monitor display device; when the command is inputted first, the control means converts video signals to have a resolution of lowest level among the resolutions that the monitor display device supports and outputs the converted video signals to the monitor display device; when the command is inputted additionally, the control means converts video signals to have a resolution higher by one level than current level among the resolutions that the monitor display device supports and outputs the converted video signals to the monitor display device; and when the command is inputted while the monitor display device displays images at highest resolution, the controller stops to output the video signals to the monitor display device.
