Display of combined first and second inputs in combined input mode

Abstract

A first processing unit provides a first input. The first processing unit has a first architecture on which a first operating system is run having a first operating environment in which first applications are run. A switching unit selects both the first and a second input in a combined input mode. The second input is provided by a second processing unit having a second architecture in which a second operating system is run having a second operating environment in which second applications are run. A scaler combines the first and second inputs into an orientation comprising a full screen of the first operating environment and a window of the second operating environment, where the window of the second operating environment is overlaid into the full screen of the first operating environment. The scaler transmits the combined first and second inputs to a display unit for display on a screen.
