Abstract

A real-time messaging system for an image display device is provided. One disclosed embodiment includes an image display device including a light source and an image-generation device configured to receive light from the light source, and in response, generate an image. The image display device may further include a projection lens configured to display the image on a viewing surface. The image display device may also include memory and a processor operatively coupled with the memory to receive a command message sent to a select group of image display devices in real-time via a network, and upon recognizing the command message, display an alert image.

Claims

1. A method of selectively transmitting a command message in real-time to an image display device, the method comprising:

selecting an image display device from a group of image display devices;

interrupting a current mode of the image display device; and

transmitting a command message in real-time to the image display device via a network, the command message including code interpretable by the image display device for generating an alert image.

2. The method of claim 1, wherein interrupting the current mode of the image display device includes interrupting a powered-off mode of the image display device, the method further comprising, in response, powering on the image display device.

3. The method of claim 1, wherein the code of the command message includes instructions for adjusting one or more display settings of the image display device.

4. The method of claim 1, wherein the code of the command message includes a command line interface prefix indicating a print text command.
