Abstract

A radio message display system for transmitting a message entered on an input device over a radio link which is set up by a paging transmitter and a paging receiver, the message being displayed on a display panel. A transmit side is provided with an encoder for coding the message entered on the input device, and the paging transmitter adapted to modulate a carrier by the coded message and transmitting the modulated carrier. A receive side, on the other hand, is provided with the display panel in which the paging receiver is accommodated for receiving and demodulating the carrier. The receiver may display the message on a display section thereof or deliver it to an external output terminal thereof. The display panel supplied with the message via the output terminal of the receiver displays it on another display section.

Claims

1. A radio message display system for displaying a message entered by transmitting the message over a radio link, comprising:

an input device for entering a message;

an encoder for coding an output of said input device;

a paging transmitter for modulating a carrier by an output of said encoder and transmitting said modulated carrier as a radio carrier;

a paging receiver having a receiving and demodulating section for receiving and demodulating the radio carrier to produce said message, a display section for displaying said message on said paging receiver, and an output terminal for outputting said message at the same time as said message is being received; and

a display panel having an input terminal and a mounting section for mounting said paging receiver, said message being supplied from said output terminal to said input terminal when said paging receiver is mounted in said display panel, and a display for displaying said message from said input terminal.

2. The radio message display system of claim 1, wherein said display panel is T-shaped.

3. A message display system, comprising:

a radio pager and a display panel;

said radio pager including;

a display section;

first means for receiving a message transmitted over a radio carrier wave;

means for displaying the message on said display section;

output terminal means for issuing an output signal representative of said message; and

means for supplying the message to said output terminal means at the same time as said message is being received;

said display panel including;

a display;

input terminal means for being connected to said output terminal means when said radio pager is mounted in said display panel;

means for mounting said radio pager;

means for receiving the message delivered to said input terminal means from said output terminal means; and

means for displaying the message on the display.

4. The message display system of claim 3, wherein said display panel is T-shaped.

5. A method for displaying a radio transmitted message, comprising the steps of:

receiving a message transmitted over a radio link by means of a radio pager having a display section;

displaying the message on said display section;

mounting said radio pager in a display panel having a display;

applying the received message to said display panel at the same time as said message is being received; and

displaying the message on said display.

6. A radio message receiver, comprising:

means for receiving a radio carrier carrying a message;

demodulating means for demodulating said message from said radio carrier;

a display section for displaying said message thereon;

control means coupled to said demodulating means for receiving said message and supplying said message to said display section for being displayed thereon; and

auxiliary output means coupled to said control means for transmitting said message to an a auxiliary display device at the same time as said message is being received.

7. The radio message receiver of claim 6, further comprising a read only memory coupled to the control means for controlling same.

8. A combination of a large display panel and a radio pager, comprising:

said large display panel including;

a display panel housing;

a display control circuit;

a display mounted to the housing and coupled to said display control circuit for displaying thereon a message in characters large enough for simultaneous viewing by several persons from a greater than a predetermined distance;

mounting means for mounting in the housing a radio pager;

said radio pager including control means for receiving said message by detecting and demodulating a radio carrier carrying said message, a display section mounted on said radio pager, said control means being effective for displaying said message on said display section, output means in said radio pager for transmitting an electrical signal representative of said message to said display control circuit of said large display panel essentially at the same time as when said message is being received and is being transmitted to said display section;

said mounting means for said radio pager including means for connecting said output means of said radio pager to said large display panel for displaying thereon said message.

9. The combination of claim 9, wherein said large display panel comprises an input terminal for being mated to said output means of said radio pager when said radio pager is mounted in said large display panel.

10. The combination of claim 9, wherein said large display panel further comprises a character generator for receiving said electrical signal and for converting said electrical signal to electrical signals suitable for driving said display to cause said message to be displayed thereon.

11. The large display panel of claim 10, wherein said electrical signal is comprised of several signal fields.

12. The large display panel of claim 11, wherein said signal fields include a bit sync field, a frame sync field, an address field, a command field, data field, and an error-correcting code field.
