- 2. An apparatus according to claim 1, wherein the operation key means comprises an X-Y input device and two trigger buttons, and the display means comprises a liquid crystal display on which is displayed the video signal by operating the X-Y device and the two trigger buttons.
- 3. An apparatus according to claim 1, wherein the control means con, rises means for displaying the operation key icons in a peripheral portion on the screen, and for changing display portions on the screen of the operation key icons displayed on the screen.
- 4. An apparatus according to claim 1, further comprises audio reproducing means for reproducing an audio signal on the basis of the digital audio data on disc, and the control means controls the audio reproducing means in response to the control information signals from the operation key means when the video signal is not displayed on the screen.
- 5. An apparatus according to claim 4, wherein the operation key icons displayed on the screen are similar in appearance to conventional manually operated "PLAY", "STOP", and "AMS" keys.
- 6. An apparatus according to claim 1, wherein, prior to any actuation of the operation keys, the control means causes the display means to display the decoded video signal but not the operation key icons and wherein, after the operation of one of the operation keys, the control means causes the display means to simultaneously display the decoded video signal and the operation key icons.
