Abstract

A method, operable in a keyboard, video, mouse (KVM) system in which multiple target computers connected to a KVM switch are accessible via the KVM switch by a remote computer connected to the KVM switch, each of the target computers having a video output, and in which one or more preselected images are each associated with corresponding actions, the method includes monitoring the video output of at least some of the target computers connected to the KVM switch to search for one of the preselected images in the video output; and when one of the preselected images is detected in a video output of one of the target computers, taking the corresponding actions associated with that image.

Claims

1. A method, operable in a keyboard, video, mouse (KVM) system in which multiple target computers connected to a KVM switch are accessible via the KVM switch by a remote computer connected to the KVM switch, each of the target computers having a video output, and in which one or more preselected images are each associated with corresponding actions, the method comprising:

monitoring the video output of at least some of the target computers connected to the KVM switch to search for one of the preselected images in the video output; and

when one of the preselected images is detected in a video output of one of the target computers, taking the corresponding actions associated with that image.

2. The method of claim 1 wherein the actions associated with an image are selected from the actions comprising:

(a) sending an alert to an operator,

(b) capturing and storing the image, and

(c) responding to the image.

3. The method of claim 2 wherein responding to the image comprises:

sending instructions to the one of the target computers.

4. A device, operable in a keyboard, video, mouse (KVM) system in which multiple target computers connected to a KVM switch are accessible via the KVM switch by a remote computer connected to the KVM switch, each of the target computers having a video output, and in which one or more preselected images are each associated with corresponding actions, the device configured to:

monitor the video output of at least some of the target computers connected to the KVM switch to search for one of the preselected images in the video output; and

when one of the preselected images is detected in a video output of one of the target computers, to take the corresponding actions associated with that image.

5. The device of claim 4 wherein the actions associated with an image are selected from the actions comprising:

(a) sending an alert to an operator,

(b) capturing and storing the image, and

(c) responding to the image.

6. The device as in claim 4 wherein the device is included in the KVM switch.
