In order to exchange various image data such as the above, various data is exchanged with the personal computer 50 via the communication control I / F 200 as various image data as communication data.

  For example, the image data stored in the ROM / RAM 303 is displayed on the PDP main body 100 at a preset time in conjunction with the timer 203 provided in the communication control I / F 200. At this time, the video input control unit 302 transmits control data for displaying the video on the PDP main unit 100, that is, for switching the input.

External control can be performed using various communication formats, such as, and by using various communication formats, it is not necessary to assume control problems caused by the communication format, and the control range can be expanded freely. be able to.

  In this embodiment, the discharge type PDP 10 is used as a display panel. However, the present invention is not limited to this and can be applied to a CRT or a liquid crystal display.

  In this embodiment, when the communication control I / F 200 is connected to the PDP 10 main body, an operation instruction signal is output to the communication control I / F 200 via the system control unit 112. You may make it output to the communication control I / F200 directly from the operation input part 110 not via the system control part 112. FIG.

  In the present embodiment, the personal computer 50 is used as the external control device. However, the present invention is not limited to this, and a communication terminal device such as a portable terminal device or a dedicated communication control device may be used.

  In the present embodiment, when the communication control unit 202 I / F is connected to the PDP main body unit 100, an operation instruction signal indicating the user instruction content input via the operation input unit 110 is transmitted to the communication control I / F. The system control unit 112 is input to the F200 via the system control unit 112 and based on an instruction from the communication control unit 202 I / F. The operation instruction signal related to some control is as follows. The system control unit 112 may directly control each unit without going through the communication control unit 202 I / F.

  In this embodiment, the video I / F 300 is connected to the communication control I / F 200 via the PDP main body 100. However, the video I / F 300 is not limited to this, and is directly connected to the communication control unit 202 I / F. You may make it do.

  In this embodiment, when the schedule data is stored in advance in the ROM / RAM 204 by a dedicated member for setting the communication control I / F 200 and the communication control I / F 200 is attached to the PDP main unit 100, the timer 203 It is also possible to operate the system control unit 112 based on the current time and the schedule data.

  In this embodiment, image data is input to the video I / F 300. However, an input terminal for a pointing device such as a video game operation device is provided, and the main body of the PDP is accompanied with video of the video game. 100 may be displayed on the screen by the pointing device.

It is a block diagram which shows the system structure of PDP in one Embodiment which concerns on this application. It is a figure for demonstrating the shape of the communication control interface and video interface with which the PDP main-body part of one Embodiment is mounted | worn.
