Abstract

Disclosed is a remotely controlled display system in which various forms of messages may be remotely provided to a display, and information regarding the display and/or the message may be provided to the control location. The information provided to the control location may be status information regarding the status of the message or the message medium, which may be, for example, a billboard or other sign, or it may be the verification of the message(s) sent to the remote location for display.

Claims

1. A display system including a display medium means having a display medium for displaying messages, and central processing means disposed at a remote location from said display medium means for initiating a message for display on said display medium, said display comprising:

first means for providing electronic communication over a transmission medium between the central processing means and remote display medium means, said first means being controlled to communicate a message from the central processing means to the display medium,

second means disposed at the remote display medium means for receiving the message and for causing text or graphic characters representing the message to be displayed on the display medium in a manner capable of being interpreted by individuals viewing the display medium, and

third means disposed at the remote display medium means for detecting the status of at least one operational parameter of displaying a message on the display medium which parameter relates to the proper display of the message on the display medium and for providing information representative thereof;

fourth means associated with the display medium for controlling the first means to electronically communicate the status information of the third means to the central processing means.

2. A display system as set forth in claim 1, wherein the third means includes means for monitoring the second means to provide status information relating to the correctness of the text or graphic characters representing the message caused to be displayed on the display medium.

3. A display system as set forth in claim 1, wherein the fourth means controls the first means to communicate the status information to the central processing means upon receipt of the message by the second means.

4. A display system as set forth in claim 1, wherein the fourth means controls the first means to communicate the status information to the central processing means upon request of the status information from the central processing means.

5. A display system as set forth in claim 1, wherein the fourth means controls the first means to communicate the status information to the central processing means at a predetermined time.

6. A display system as set forth in claim 1 wherein the central processing means includes means for composing a message comprising a processor for creating an alphanumeric message.

7. A display system as set forth in claim 1 wherein the central processing means includes means for composing a message comprising a processor for creating a graphic message.

8. A display system as set forth in claim 1 wherein the central processing means includes means for composing a message comprising a processor coupled to a digitizing means for creating a graphic message.

9. A display system as set forth in claim 1 wherein the central processing means further comprises means for storing a composed message for communication to the display medium means at a later time.

10. A display system as set forth in claim 1 wherein the central processing means includes means for generating a command for controlling a function in the operation of displaying the message on the remotely located display medium, and means for controlling the first means to communicate the command to the second means for implementation thereby.

11. A display system as set forth in claim 10 wherein the third means includes means for monitoring the second means to provide status information relating to the implementation of the command by the second means.

12. A display system as set forth in claim 1 wherein the second means includes means for receiving a plurality of messages and causing said text or graphic characters representing the received message to be displayed on the display medium in accordance with a predetermined schedule.

13. A display system as set forth in claim 12 wherein the third means includes means for monitoring the second means to provide status information relating to the proper display of the plurality of messages on the display medium in accordance with the predetermined schedule.

14. A display system as set forth in claim 1 wherein the third means includes a display sensor for detecting a malfunction in the display medium in connection with displaying the message and providing status information representative thereof.

15. A display system as set forth in claim 1 wherein the display medium means includes a source of illumination for the display medium;

and wherein the third means includes an illumination sensor for detecting a malfunction in the source of illumination and providing status information representative thereof.

16. A display system as set forth in claim 1 wherein the display medium means includes a source of power for the display medium;

and wherein the third means includes a power sensor for detecting a malfunction in the source of power and providing status information representative thereof.

17. A display system as set forth in claim 1 wherein the display medium means includes a sensor for detecting an intrusion within a proximity of said display medium means and for providing status information representative thereof.

18. A display system including a display medium means having a display medium for displaying messages, and central processing means disposed at a remote location from said display medium means for initiating a message for display on said display medium, said display comprising:

first means for providing electronic communication over a transmission medium between the central processing means and remote display medium means, said first means being controlled to communicate at least one message from the central processing means to the display medium,

second means disposed at the remote display medium means for receiving and storing the message in a memory, and for causing text or graphic characters representing at least one of the messages stored in the memory to be displayed on the display medium for a time interval, and

third means disposed at the remote display medium means for detecting the status of at least one operational parameter of displaying a message on the display medium during the time interval that the message is displayed, which parameter relates to the proper display of the message on the display medium and for providing information representative thereof;

fourth means associated with the display medium for controlling the first means to electronically communicate the status information of the third means to the central processing means.

19. A display system including a display medium means having a display medium for displaying messages, and central processing means disposed at a remote location from said display medium means for initiating a message for display on said display medium, said display comprising:

first means for providing electronic communication over a transmission medium between the central processing means and remote display medium means, said first means being controlled to communicate messages from the central processing means to the display medium,

second means disposed at the remote display medium means for receiving and storing the message in a memory, and for causing text or graphic characters representing certain messages stored in the memory to be displayed on the display medium in accordance with a message display schedule with each displayed message being displayed for a time interval, and

third means disposed at the remote display medium means for detecting the status of at least one operational parameter of displaying a message on the display medium during the time interval that the message is displayed, which parameter relates to the proper display of the message on the display medium and for providing information representative thereof;

fourth means associated with the display medium for controlling the first means to electronically communicate the status information of the third means to the central processing means.
