Control of video device by multiplexing accesses among multiple applications requesting access based on visibility on single display and via system of window visibility rules

In an information handling system, a method for controlling a video device with a video device manager, comprising:

• receiving a request by an application to access the video device, wherein a window corresponding to the application is displayable in a multi-window environment on a single display device of the information handling system;
• denying access to the video device by the application if a window corresponding to the application is not visible on the single display device of the information handling system;
• and
• providing access to the video device by the application via a system of window visibility rules if a window corresponding to the application is visible on the single display device of the information handling system.

In an information handling system, a method for controlling a video device with a video device manager, comprising:

• registering a first application executable by the information handling system with the video device manager by placing the first application on a registration list internal to the video device manager;
• receiving a request from the first application to access the video device;
• providing access to the video device by the first application;
• registering a second application executable by the information handling system with the video device manager by placing the second application on the registration list internal to the video device manager,
• receiving a request from the second application to access the video device;
• and
• providing access to the video device in a multi-window environment based upon a system of window visibility rules wherein a determination of access to the video device is based upon a visibility of a first window corresponding to the first application on a single display device and a visibility of a second window corresponding to the second application on the single display device.

An information handling system, comprising:

• a processor suitable for performing a program of instructions;
• a single display device coupled to the processor, the single display device suitable for providing a display of data;
• a video device suitable for providing video data;
• and
• a memory device coupled to the processor, the memory device suitable for storing a program of instructions, wherein the program of instructions configures the processor to provide access in a multi-window environment to the video device to one or more applications executable by the information handling system, wherein each application of the one or more applications has a corresponding window displayable on the single display device of the information handling system, and upon multiple applications of the one or more applications requesting access to the video device, configures the processor to multiplex access to the video device among the multiple applications via a system of window visibility rules of the corresponding windows as displayed on the single display device of the information handling system.
