## Abstract

A USB image transmission system is provided. The USB image transmission system may include a content source configured to be operatively coupled to a USB-enabled display device. Image data may be transmitted over the USB connection from the content source for display by the display device. In some embodiments, a USB collaboration hub may enable multiple content sources to be operatively linked through a USB connection to one or more USB-enabled display devices.

## Claims

### Claim 1

An image display system, comprising:
a plurality of display devices, each with a serial bus port, the plurality of display devices to be provided image data;
a serial bus link coupled with each of the plurality of display devices;
a content source coupled with the serial bus link, the content source to send the image data over the serial bus link to at least one of the plurality of display devices, wherein
a bulk end-point is established, through which image data is transferred, and
a control end-point is established, through which control data is transferred.

### Claim 2 (depends on 1)

The image display system of claim 1, wherein at least one of the plurality of display devices is configured to act as a moderator, wherein the moderator is configured to function as a system controller to set a collaboration mode and aggregate image content to the plurality of display devices.

### Claim 3 (depends on 2)

The image display system of claim 2, wherein the collaboration mode of the moderator is a file transfer between two of the plurality of display devices.

### Claim 4 (depends on 2)

The image display system of claim 2, wherein the collaboration mode of the moderator is configured to control which display devices may utilize the serial bus link coupled with the content source.

### Claim 5 (depends on 2)

The image display device of claim 2, wherein the collaboration mode of the moderator is an ad-hoc mode, wherein the serial bus link is open from any of the plurality of display devices to broadcast image data from the content source.

### Claim 6

An image display system, comprising:
a plurality of display devices, each with a serial bus port, the plurality of display devices to be provided image data;
a serial bus link coupled with each of the plurality of display devices;
a content source coupled with the serial bus link, the content source to send the image data over the serial bus link to at least one of the plurality of display devices, wherein
at least one of the plurality of display devices is configured to act as a moderator, wherein the moderator is configured to function as a system controller to set a collaboration mode and aggregate image content to the plurality of display devices.

### Claim 7 (depends on 6)

The image display system of claim 6, wherein the collaboration mode of the moderator is a file transfer between two of the plurality of display devices.

### Claim 8 (depends on 6)

The image display system of claim 6, wherein the collaboration mode of the moderator is configured to control which content source may utilize the serial bus link coupled with the display device.

### Claim 9 (depends on 6)

The image display device of claim 6, wherein the collaboration mode of the moderator is an ad-hoc mode, wherein the serial bus link is open from any of the plurality of display devices to broadcast image data from the content source.
