Abstract

Systems, methods, and computer-readable and executable instructions are provided for providing a video clone to a display matrix. Providing a video clone to a display matrix can include utilizing a computing device to transfer video images via Ethernet to a network interface controller (NIC) device 602 . Providing a video clone to a display matrix also can include utilizing the NIC device to transfer the video images to a plurality of displays 604 . Providing a video clone to a display matrix also can include determining a plurality of portions of the video images that correspond to the plurality of displays utilizing a display scalar 606 . Furthermore, providing a video clone to a display matrix can include associating the display scalar with each of the plurality of displays of the display matrix to display the video clone of each of the portions of video images 608.

First claim

What is claimed:

1. A method of displaying video on a display matrix of display devices, comprising:
receiving, by a first network interface controller (NIC) device of a first of the display devices, a video image via Ethernet from a computing device;
transferring the video image from the first NIC device to a second NIC device of a second of the display devices, wherein the first and second NIC devices are part of a chain of NIC devices in the respective display devices;
determining, with respective display scalars of the display devices, a plurality of portions of the video image that correspond to the display devices; and
causing display of each of the portions of the video image on the display devices.

2. The method of claim 1 , wherein the transferring of the video image comprises sending the video image from an Ethernet OUT port of the first NIC device to an Ethernet IN port of the second NIC device.

3. The method of claim 1 , further comprising determining, by the display scalar of each of the display devices, a respective orientation of the plurality of the video image.

4. The method of claim 1 , wherein the chain of NIC devices includes an Ethernet daisy chain of NIC devices.

5. A non-transitory computer-readable medium storing instructions executable by a system to cause the system to:
receive, from a network interface controller (NIC) device of a first display device, a video image received by the NIC device via Ethernet, wherein the first display device is connected via a display port connection to a second display device, the first and second display devices being part of a matrix of display devices;
convert, by the first display device, the received video image to a converted video image in a particular color space;
determine, by a display scalar in the first display device, a first portion of the received video image that corresponds to the first display device;
send, from the first display device, the converted video image via the display port connection to the second display device, to cause another portion of the received video image to be displayed using a display scalar of the second display device; and
cause display of the first portion of the received video image by the first display device.

6. The non-transitory computer-readable medium of claim 5 , wherein the second display device does not include a NIC device.

7. The non-transitory computer-readable medium of claim 6 , wherein the converted video image includes an RGB video image.

8. The non-transitory computer-readable medium of claim 6 , wherein the instructions are executable to cause the display scalar of the first display device to convert the received video image from a VoE video format to a different video format displayable by the first display device.

9. The non-transitory computer-readable medium of claim 8 , wherein the instructions are executable to cause the display scalar of the first display device to determine a size of the first portion of the received video image.

10. The non-transitory computer-readable medium of claim 5 , wherein the received video image is passed through a frame buffer to a video receiver in the first display device.

11. The non-transitory computer-readable medium of claim 5 , wherein the display devices are connected in a display chain.

12. A display matrix, comprising:
a plurality of display devices, wherein a first of the display devices comprises a first network interface controller (NIC) device to receive a video image via Ethernet from a computing device, and wherein a second of the display devices includes a second NIC device that has a packet analyzer to detect the video image sent to the first NIC device by the computing device,
wherein the plurality of display devices include respective display scalars to divide the received video image into portions for display by the respective display devices.

13. The display matrix of claim 12 , wherein the first NIC device is assigned an IP address to which the computing device sends the video image.

14. The display matrix of claim 12 , wherein the first NIC device of the first display device is a master NIC device to which the computing system sends video images, and wherein a remainder of the display devices include NIC devices that have respective packet analyzers to detect the video images sent to the master NIC device.
