Abstract

Embodiments of the invention are generally directed to an integrated mobile desktop. An embodiment of an apparatus includes a display chip to receive graphical data and produce video display signals; and a logic chip to receive data from a mobile device and the video display signals from the display chip to generate a display including at least a portion for a representation of a display of the mobile device. The logic chip provides for integration of operations for the apparatus and the mobile device using the generated display.

Claims (36)

1. An apparatus comprising:

a display chip configured to:

receive graphical data from a component of the apparatus using a first video communication protocol, and

produce video display signals based on the received graphical data;

a logic chip separate from the display chip to receive data from a second apparatus using a second video communication protocol and the video display signals from the display chip using a third video communication protocol to generate a display including at least a portion for a representation of a display of the second apparatus; and

a memory component accessible by the logic chip to store or retrieve High-bandwidth Digital Content Protection (HDCP) data, the memory component separate from a memory of the apparatus and not accessible by a central processing unit of the apparatus;

wherein the logic chip provides for integration of operations for the apparatus and the second apparatus using the generated display.

2. The apparatus of claim 1 , wherein the operations include manipulation of data on the second apparatus using controls for the apparatus or a computer coupled with the apparatus.

3. The apparatus of claim 1 , wherein the operations include transfer of data between the second apparatus and the apparatus or a computer coupled with the apparatus.

4. The apparatus of claim 1 , wherein the apparatus is a personal computer.

5. The apparatus of claim 1 , wherein the second apparatus is a mobile device.

6. The apparatus of claim 1 , wherein the apparatus is a display monitor to be coupled with a computer.

7. The apparatus of claim 1 , wherein the logic chip provides protection for secure video data by separating the secure video data from other data.

8. The apparatus of claim 1 , wherein the first video communication protocol is one of Video Graphics Array (VGA), Digital Visual Interface (DVI) or High-Definition Multimedia Interface (HDMI).

9. The apparatus of claim 8 , wherein the second video communication protocol is Mobile High-definition Link (MHL).

10. The apparatus of claim 9 , wherein the third video communication protocol uses low-voltage differential signaling (LVDS).

11. The apparatus of claim 1 , wherein the first video communication protocol uses low-voltage differential signaling (LVDS).

12. The apparatus of claim 11 , wherein the second communication protocol is one of Mobile High-definition Link (MHL), High-Definition Multimedia Interface (HDMI) or display port (DP).

13. A method comprising:

receiving, by a display chip of a first device, graphical data from a component of the first device using a first video communication protocol;

producing, by the display chip of the first device, video display signals based on the received graphical data;

discovering, by a logic chip of the first device separate from the display chip, a second device connected to a port of the first device;

establishing a connection between the logic chip of the first device and the second device using a second video communication protocol;

receiving, by the logic chip of the first device, data from the second device using the second video communication protocol and the video display signals from the display chip of the first device using a third video communication protocol;

storing High-bandwidth Digital Content Protection (HDCP) data of the data received from the second device in a memory component of the first device accessible by the logic chip, the memory component separate from a memory of the first device;

preventing access to the HDCP data by a central processing unit of the first device;

providing interface control between the first device and the second device using the second video communication protocol;

generating, by the logic chip of the first device based on the data received from the second apparatus and the video display signals, an active representation of a display of the second device for presenting in a display of the first device; and

translating one or more actions in using the display of the first device into an operating system of the first device and an operating system of the second device.

14. The method of claim 13 , further comprising separating the received data between the video output data and other data.

15. The method of claim 13 , wherein the one or more actions include manipulation of the second device using controls of the first device.

16. The method of claim 13 , wherein the one or more actions include transfer of data between the first device and the second device using the active representation of the display of the second device in the display of the first device.

17. The method of claim 13 , wherein the first apparatus is a computer.

18. The method of claim 13 , wherein the second apparatus is a mobile device.

19. The method of claim 13 , wherein the first video communication protocol is one of Video Graphics Array (VGA), Digital Visual Interface (DVI) or High-Definition Multimedia Interface (HDMI).

20. The method of claim 19 , wherein the second video communication protocol is Mobile High-definition Link (MHL).
