The operation of the terminal display device will be described from an initial state where no transmission ID is stored in the transmission ID memory 11 in advance. The communication control unit 13 receives a signal from the information control device 1 via the communication line 2,
And the receiving ID is separated and output ST1. Reception control unit 14
Is compared with the reception ID of the own terminal display device stored in the reception ID memory, and if they match, the transmission ID memory 1
Confirm that no transmission ID is stored in ST1 and ST2,
It is determined that there is no storage, and the received transmission ID is stored in the transmission ID memory and written ST4. Further received transmission ID
When it is confirmed that the received ID matches the received ID stored in the received ID memory 11, a command code is received and output. The command determining unit 16 determines the received command code using the table of the command code and the control data stored in the command code memory 15 to determine the control command ST6, and determines whether the display program and the display data have been received. Then, it is stored in the display program memory 17 and the display data memory 18. On the other hand, if the reception ID or the transmission ID does not match, the subsequent reception is stopped.

In the normal operation state, the first transmission I
The display control unit 19 reads out display data from the display data memory 18 according to the display program in the display program memory 17 and generates video and audio data according to the control code from the information control device D. Image data is PDP
(Plazma Display Panel) and the like, and the audio data is output as audio from an audio output unit 21 such as a speaker. During this time, the inter-terminal table device 10 does not receive and input a control code from another information control device 1A.

When the information control unit 1 stops transmitting the display data and transmits a transmission ID erasure code for instructing erasure of the transmission ID of the information control device, the instruction determination unit 18 determines the transmission ID in the transmission ID memory. At the same time, the input from the other information control unit 1A is restarted.

An electronic signboard device or an electronic bulletin board device according to an application of the present invention automatically switches the information source according to the time zone or the day of the week to receive and display display data. For example, at 7:00 in the morning, a news program or the like from the information control device (A) 1 shown in FIG. At 8:29, the information control device (A) 1 sends a transmission ID erasure code for instructing the transmission ID of the information control device to be erased, and makes it possible to receive from the next information control device (B) 1A. . 8:30
At the same time, the information control device (B) 1A starts transmission of the received program data of the ticket. The electronic signboard device and the electronic bulletin board device are in the initial state described in the previous section because the transmission ID of the transmission ID memory 11 has already been deleted, and transmit the received transmission ID of the information control device (B) 1A. The information can be stored in the ID memory 11 and can be continuously displayed. Thereafter, the information control device sends the transmission ID for each required time.
By sending the erasure code, the selection of the information control device is made automatically.

[0018]

The present invention is implemented in the state described above, and has the following effects. The control command from the information control device having the preset transmission ID is preferentially received.
When a command to stop reception is received from the information control device, the reception is stopped, and after the reception is stopped, the control command from the information control device of another transmission ID received first is preferentially received. When the transmission ID is not stored in the transmission ID memory, the received transmission ID is additionally stored in the transmission ID memory and the display data from the information control device is received. Thereafter, reception control is performed in accordance with a control command from another information control device. As described above, the terminal display device can automatically receive and display control commands from a plurality of information control devices, display programs and display data without depending on control of only a specific information control device. became. Furthermore, the revision of the displayed program is also handled by the information control device side, and switching of all terminal display devices can be remotely controlled.
