Abstract

Systems and methods for communicating private information from a browser to a driver are presented. The private information communication method can comprise: performing a private information communication process in which private information is communicated through a private information communication plug-in of a browser to a driver; and performing a driver process based upon the private communication information communicated in the private information communication process. The private information communication process can comprise determining private information content; communicating the private information to the private information communication plug-in coupled to a private communication channel; calling a graphics driver from the private information communication plug-in using the private communication channel; and forwarding the private information from the private information communication plug to the driver via the private communication channel. The driver process can comprise: determining if there is an association between normal information and the private information, and processing the normal information in accordance with associated private. The private information can be associated with stereoscopic 3D video streaming.

Claims

1. A private information communication method comprising:

performing a private information communication process in which private information is communicated through a dedicated private communication channel from a private information communication plug-in of a browser to a driver, wherein the dedicated private communication channel includes a backdoor interface, wherein the private information includes browser information that would otherwise not be communicated to the driver, wherein the private information further includes stereoscopic video information associated with graphics surface information; and

performing a driver process based upon the private communication information communicated in the private information communication process.

2. The private information communication method of claim 1 wherein the private information communication process comprises:

determining private information content;

communicating the private information to the private information communication plug-in coupled to the dedicated private communication channel;

calling a graphics driver from the private information communication plug-in using the dedicated private communication channel; and

forwarding the private information from the private information communication plug-in to the driver via the dedicated private communication channel.

3. The private information communication method of claim 1 wherein said private information includes metadata.

4. The private information communication method of claim 1 wherein said private information includes arguments.

5. The private information communication method of claim 1 wherein the driver process comprises:

determining if there is an association between normal information and the private information, and

processing the normal information in accordance with associated private information.

6. A computer system comprising:

a system operable to implement a display driver component which is operable to perform graphics processing unit interface operations with a display component, wherein the graphics processing unit interface operations with a display component include processing graphics surface information received from a normal information communication channel utilizing private information received via a dedicated private communication channel, wherein the dedicated private communication channel includes a backdoor interface, wherein the private information includes stereoscopic video information associated with the graphics surface information, wherein a graphics processor device is included in the system; and

the system operable to implement a browser component operable to forward the private information to the graphics processing unit display driver component via the private information communication channel through a dedicated private information communication plug-in of the browser component.

7. The computer system of claim 6 wherein the browser includes an application component.

8. The computer system of claim 7 wherein the browser includes a runtime component.

9. The computer system of claim 6 wherein the browser includes a java script component.

10. The computer system of claim 6 wherein the private information communication plug-in is installed when the driver is installed.

11. The computer system of claim 6 wherein the metadata includes the width of the player window, the height of the player window, the stereo mode, a flag indicating whether to enable or disable stereoscopic 3D rendering and process ID.

12. A non-transitory computer readable medium operable to store instructions for directing processor operations in a private communication process, wherein the private communication process comprises:

performing a private information communication process in which private information is communicated through a private information communication plug-in of a browser to a driver, the private information communication plug-in coupled to a dedicated private communication channel, wherein the dedicated private communication channel includes a backdoor interface; and

performing a driver process based upon the private communication information communicated in the private information communication process, wherein the private information includes stereoscopic video information associated with graphics surface information, wherein calls associated with normal information from an application communicated on a normal information communication channel are intercepted by the driver and processed utilizing corresponding portions of the private information communicated on the private channel.

13. The non-transitory computer readable medium of claim 12 wherein the private information communication process comprises:

determining private information content;

communicating the private information to the private information communication plug-in;

calling a driver from the private information communication plug-in using the dedicated private communication channel, and forwarding the private information from the private information communication plug-in to the driver via the dedicated private communication channel.

14. The non-transitory computer readable medium of claim 12 wherein the private information includes metadata.
