Abstract

A network messaging protocol enabling messages from multiple network devices to share a single display device is disclosed. The protocol enables a display device to prioritize among incoming messages from different network devices and to prioritize among incoming multiple messages from a single device. The protocol further enables multiple networked devices communicating over an IP based network to share a display device, and also provides the ability for a network device to specify the display characteristics of its message. A display device executing the messaging protocol processes and displays multiple messages from multiple network devices without the need to overwrite important messages or display messages in unreadable sizes.

Claims

1. A method for displaying messages on a display device, said messages originating from a plurality of networked electronic devices communicating with the display device over a network, said method comprising the steps of:

providing a protocol to enable a plurality of networked devices to send messages to a display device;

registering a plurality of networked electronic devices with said display device, in response to a registration request from each of the networked electronic devices, prior to said display device displaying any messages from the plurality of networked electronic devices, the display device assigning an identifier to each of the networked electronic devices upon registration;

the display device sending the assigned identifiers to the plurality of networked electronic devices in response to the registration; and

creating, in response to the registering of the plurality of networked electronic devices with said display device, a separate priority message queue on said display device for each of the plurality of networked electronic devices registered with the display device, each priority message queue having a priority level assigned to it based on an identity of that registered networked electronic device, each display message received by the display device from that registered networked electronic device being placed in the priority message queue that is assigned to that networked electronic device;

creating a unique message ID identifying each message placed in said priority message queue of a given networked electronic device;

selecting a highest priority message queue among the priority message queues, said priority message queue containing at least one message;

selecting from within said highest priority message queue a message with highest message priority level; and

displaying said selected message on said display device.

2. The method of claim 1 wherein the network is an Internet Protocol (IP) based network.

3. The method of claim 1 wherein said registering further comprises:

sending to the display device a text string representing a device name for at least one of the networked electronic devices.

4. The method of claim 1 wherein said method further comprises the step of:

sending to the display device a graphical image representing at least one of the networked electronic devices.

5. The method of claim 1, said method comprising the additional steps of:

receiving a display message at the display device from a given one of the networked electronic devices; and

placing the received display message in the priority message queue for the given networked electronic device.

6. The method of claim 5 wherein said received display message in the priority message queue for the given networked electronic device contains text.

7. The method of claim 5 wherein said received display message in the priority message queue for the given networked electronic device contains a graphical image.

8. The method of claim 5 wherein said received display message in the priority message queue for the given networked electronic device contains both text and a graphical image.

9. The method of claim 5, said method comprising the additional steps of:

providing a priority level for each display message sent from the given networked electronic device to the display device; and

creating a unique message ID identifying each message placed in said priority message queue of said given networked electronic device.

10. The method of claim 5, said method comprising the additional step of:

sending a request to said display device from a registered networked electronic device that is registered with the display device to remove a message from the priority message queue of said registered networked electronic device.

11. The method of claim 5, said method comprising the additional step of:

sending a list of Message IDS appearing in a priority message queue from said display device to a particular networked electronic device registered with said display device in response to a request from said particular networked electronic device.

12. The method of claim 5, said method comprising the additional step of:

sending a status message providing a current status of a message in a priority message queue from said display device to a registered networked electronic device registered with said display device in response to a request from said registered networked electronic device.

13. The method of claim 5, said method comprising the additional step of:

including display instructions as part of the display message sent to said display device by the given networked electronic device registered with said display device.

14. The method of claim 5, said method comprising the additional step of:

unregistering said given networked electronic device registered with said display device.

15. The method of claim 1 wherein said messages are written using extensible markup language (XML).

16. A computer-readable storage medium for use with a display device with a network interface, said computer-readable storage medium holding computer executable instructions when executed by a computer to perform a method comprising the steps of:

providing a protocol to enable a plurality of networked electronic devices to send messages to a display device, and registering a plurality of networked electronic devices with said display device, in response to a registration request from each of the networked electronic devices, prior to said display device displaying any messages from the plurality of networked electronic device, the display device assigning an identifier to each of the networked electronic device upon registration;

the display device sending the assigned identifier to the networked electronic devices in response to the registration;

creating, in response to the registering of the plurality of networked electronic devices with said display device, a separate priority message queue on said display device for each of the plurality of networked electronic devices registered with the display device, each priority message queue having a priority level assigned to it based on an identity of a corresponding registered networked electronic device, each display message received by the display device from a registered networked electronic device being placed in a priority message queue that is assigned to said networked electronic device;

creating a unique message ID identifying each message placed in said priority message queue of a given networked electronic device;

selecting a highest priority message queue among the priority message queues, said priority message queue containing at least one message;

selecting from within said highest priority message queue a message with highest message priority level; and

displaying said selected message on said display device.

17. The medium of claim 16 wherein said network is an Internet Protocol (IP) based network.

18. A method for displaying messages on a display device, said messages originating from a plurality of networked electronic devices communicating with the display device over a network, said method comprising the steps of:

providing a protocol to enable a plurality of networked devices to send messages to a display device;

registering a plurality of networked electronic devices with said display device, in response to a registration request from each of the networked electronic devices, prior to said display device displaying any messages from the plurality of networked electronic devices, the display device assigning an identifier to each of the networked electronic devices upon registration;
