Abstract

A remote control apparatus is disclosed, in which a first remote control device and a second remote control device can be separated or combined. A configuration is also disclosed in which a remote control apparatus including a first remote control device and a second remote control device controls a display apparatus. Also disclosed is a display apparatus controlled by a remote control apparatus including a first remote control device and a second remote control device that can be separated or coalesce.

Claims

1. A display apparatus operated by a remote control apparatus including a first remote control device and a second remote control device that can be switched between a combined state and a separated state, said display apparatus comprising:

a display unit; and

a communication portion to communicate with the first and the second remote control devices,

wherein a number of display picture frames displayed on said display unit is changed in accordance as the first remote control device and the second remote control device are combined with, or are separated from, each other.

2. A display apparatus according to claim 1, wherein control for increasing the number of display picture frames is performed in response to separation of the first remote control device and the second remote control device from each other.

3. A display apparatus according to claim 1, wherein control for reducing the number of display picture frames is performed in response to combination of the first remote control device and the second remote control device with each other.

4. A display apparatus operated by a remote control apparatus including a first remote control device and a second remote control device that can be switched between a combined state and a separated state, said display apparatus comprising:

a display unit; and

a communication portion, to communicate with the first and the second remote control devices,

wherein each of different picture frames displayed on said display unit is controlled in accordance with operations of a corresponding one of the first remote control device and the second remote control device.

5. A display apparatus controlled by operating a remote control device, comprising:

a display unit where a plurality of display picture frames are displayed; and

a transmission circuit for transmitting to the remote control device a voice signal corresponding to a predetermined one of the picture frames controlled by operations of the remote control device from among the plurality of picture frames.

6. A display apparatus controlled by operation of a remote control device, comprising:

a display unit for forming one or more display picture frames;

a control circuit for performing control so as to form the one or more display picture frames on said display unit;

a circuit for receiving a signal for controlling a predetermined picture frame from among the plurality of display picture frames, from the remote control device; and

a circuit for transmitting a voice signal corresponding to the predetermined picture frame to the remote control device.

7. A remote control apparatus for controlling a display apparatus, comprising:

a first remote control device; and

a second remote control device,

wherein the first remote control device and the second remote control device can be switched between a state in which these devices are combined and a state in which these devices are separated, and

wherein a picture frame newly displayed on the display apparatus in response to the first remote control device and the second remote control device being switched from the combined state to the separated state is controlled by one of the first remote control device and the second remote control device.

10. A remote control apparatus according to claim 7, wherein a signal for discriminating between the state in which the first remote control device and the second remote control device are combined, and the state in which the first remote control device and the second remote control device are separated, is output by one or the other of the remote control devices.

14. A remote control apparatus according to claim 7, wherein at least one of the first remote control circuit and the second remote control circuit includes a circuit for receiving a voice signal.

8. A remote control apparatus for controlling a display apparatus, comprising:

a first remote control device; and

a second remote control device,

wherein the first remote control device and the second remote control device can be switched between a state in which these devices are combined and a state in which these devices are separated, and

wherein, when the first remote control device and the second remote control device are switched from the separated state to the combined state, one of the remote control devices generates a signal for stopping display of a picture frame display of which had been under control of one or the other of the first display device and the second display device.

11. A remote control apparatus according to claim 8, wherein a signal for discriminating between the state in which the first remote control device and the second remote control device are combined, and the state in which the first remote control device and the second remote control device are separated, is output by one or the other of the remote control devices.

15. A remote control apparatus according to claim 8, wherein at least one of the first remote control circuit and the second remote control circuit includes a circuit for receiving a voice signal.

9. A remote control apparatus for controlling a display apparatus, comprising:

a first remote control device; and

a second remote control device,

wherein the first remote control device and the second remote control device can be switched between a state in which these devices are combined and a state in which these devices are separated, and

wherein the first remote control device controls a first picture frame from among a plurality of picture frames displayed on the display apparatus and the second remote control device controls another picture frame from among the plurality of picture frames.

12. A remote control apparatus according to claim 9, wherein a signal for discriminating between the state in which the first remote control device and the second remote control device are combined, and the state in which the first remote control device and the second remote control device are separated, is output by one or the other of the remote control devices.

16. A remote control apparatus according to claim 9, wherein at least one of the first remote control circuit and the second remote control circuit includes a circuit for receiving a voice signal.

13. A remote control apparatus for controlling a predetermined apparatus, comprising:

a first remote control device;

a second remote control device, wherein the first remote control device and the second remote control device can be switched between a state in which these devices are combined and a state in which these devices are separated; and

a transmission circuit for outputting a signal for discriminating between the state in which the first remote control device and the second remote control device are combined and the state in which the first remote control device and the second remote control device are separated.

17. A remote control apparatus according to claim 13, wherein at least one of the first remote control circuit and the second remote control circuit includes a circuit for receiving a voice signal.
