In this case, the video / audio signal editing unit 220 receives the output signal sent from the video / audio signal processing unit 210, and the control signal generator 260 generates a control signal to edit the video / audio signal. You. Thereby, for example, all of the contents, images, sounds, etc. can be edited. Therefore, the user can edit data, display images, and the like into a desired format. In the above example, the case where a video / audio signal is transferred has been described, but a signal from a network page can also be processed by the built-in browser. The signal is transmitted from, for example, an Internet-connected mobile phone, a handheld computer, or a wristwatch having a network connection function.

One of the main components of the control signal generator 260 is a control signal processing unit 266 for processing a control signal.
A control signal from the control device 300 is received via the RF receiver 62 and the RF receiver 264. Also, the control signal processing unit 266
Can also receive a control signal from the control device 300 via the connection cable 268. FIG. 4 is a block diagram illustrating a functional relationship between various components in the control device illustrated in FIG. The control device 300 may be a cable connection or a wireless handheld controller, and includes a control panel 310 and a control signal transfer unit 320. In addition, the control device 300 transmits the RF transmitter 330 and the antenna 34
0 may be provided. Alternatively, the control device 300 is connected to the control signal generator 26 via a cable 350 provided separately.
0 may be connected to the cable 268. Control device 30
0 mainly performs the function of editing various signals such as images, sounds, and network pages.

The controller 300 may be a remote controller or a cable-connected controller, and is operated by a simple input keyboard or a combination of a trackball and an enter button. The screen of the wireless headset display device displays a function selection page, and the user can operate a cursor (indicated by an arrow or the like) on the page with a trackball. In this way, by combining the movement of the cursor with the enter button,
Operations on the display screen, such as moving to the previous page and the next page, can be performed. Since this display screen is of the same type as the monitor of the desktop computer, the operation of the control device 300 is almost the same as the mouse operation of the computer. Therefore, control device 300 simplifies the operation of the display screen. The wireless headset display device of the present invention has a very wide range of application,
Roughly, it can be used for any type of personal portable device where data can be transferred via a wireless medium.

When a personal portable device such as a VCD playback device or a DVD playback device is a device capable of wireless transfer, a video / audio signal is wirelessly transferred from an information signal generator in the playback device to a headset display device. be able to. So, if you start your personal portable device and wear a wireless headset, you can enjoy watching videos and viewing information privately in public places and in transportation such as buses, trains, or airplanes.
