Smart cable for controlling video capture device
View Patent ↗An element, such as a plug on a VGA cable, can communicate with a media storage unit to enable or disable media storage.
1. An element adapted to transfer a video signal, the element adapted to be connected to a presentation device to provide the video signal to a display device, the element including a switch with an on-state and an off-state, wherein, when the switch is in the on-state, storage of media from the presentation device is enabled and, when the switch is in the off-state, storage of media from the presentation device is disabled, and wherein the switch in the off state does not disable the display of the media by the display device.
2. The element of claim 1 , wherein the element is part of a video cable.
3. The element of claim 1 , wherein the element is a plug of a video cable.
4. The element of claim 1 , wherein the element connects to a video cable.
5. The element of claim 1 , wherein the element includes a display to indicate a state of the element.
6. The element of claim 1 , wherein the switch state is encoded mechanically.
7. The element of claim 1 , wherein the switch state is encoded electronically.
8. The element of claim 1 , wherein the switch is operated manually.
9. The element of claim 1 , wherein the switch changes to a default state when the element is unplugged.
10. The element of claim 1 , wherein the switch must be switched from its default state for the element to be attached.
11. The element of claim 1 , wherein the element transfers an indication of the switch state using one or more lines of the video cable cord.
12. The element of claim 1 , wherein the storage is enabled and disabled at the media storage unit.
13. The element of claim 11 , wherein the element sends an indication to the media storage unit.
14. The element of claim 11 , wherein media storage unit detects a line of the video cable being grounded to determine whether to store the media.
15. The element of claim 11 , wherein media storage unit examines an image to determine whether to store the media.
16. A video cable comprising:
a video cable cord; and
a plug attached to the video cable cord, wherein the plug is adapted to be connected to a presentation device to provide a video signal to a display device, the plug including a switch with an on-state and an off-state, wherein, when the switch is in the on-state, storage of media from the presentation device is enabled and, when the switch is in the off-state, storage of media from the presentation device is disabled, and wherein the switch in the off state does not disable the display of the media by the display device.
17. The video cable of claim 16 , wherein the switch changes to a default state when the video cable cord is unplugged.
18. The video cable of claim 16 , wherein the switch is operated manually.
19. The video cable of claim 16 , wherein the video cable is a VGA cable.
20. The video cable of claim 16 , wherein the plug indicates the switch state when the video cable cord is unplugged.
21. The video cable of claim 16 , wherein the switch must be switched from its default state for the plug to be attached.
22. The video cable of claim 16 , wherein the plug transfers an indication of the switch state using one or more lines of the video cable cord.
23. The video cable of claim 16 , wherein the plug transfers an indication of the switch state using a DDC message.
24. The video cable of claim 16 , wherein the storage is enabled and disabled at a media storage unit.
25. The video cable of claim 22 , wherein media storage unit detects a line of the video cable being grounded to determine whether to store the media.
26. The video cable of claim 22 , wherein media storage unit examines an image to determine whether to store the media.
27. The video cable of claim 22 , wherein media storage unit examines a DDC message to determine whether to store media.
