Method and apparatus for controlling video content on a display

A computer readable storage medium having stored therein instructions, which when executed by a processor cause:

• detecting a first input gesture by a user on a touch interface device;
• in response to detecting the first input gesture, selecting an application for display on a display screen from a set of two or more applications displayed on the display screen, wherein the two or more applications are secondary digital content displayed in an overlay above a primary video stream on the display screen;
• detecting a second input gesture by the user on the touch interface device;
• in response to detecting the second input gesture, scrolling through a currently-displayed layer of the selected application displayed on the display screen, wherein scrolling through the currently-displayed layer takes place in an X-Y plane on the display screen;
• detecting a third input gesture by the user on the touch interface device;
• and
• in response to detecting the third input gesture, scrolling between layers of the selected application in a simulated Z-space on the display device.

A controller for controlling a display device, comprising:

• (a) a touch screen display;
• (b) a processor;
• and
• (c) a computer readable medium storing instructions for controlling the processor to perform operations during execution performed by the processor, wherein the operations comprise:
• displaying a user interface for control of secondary digital content in an overlay above a primary video stream on a display device, wherein the user interface includes only a line from top to bottom separating the user interface into a left side and a right side, wherein the user interface includes no custom buttons or keys;
• detecting a first input gesture by a user on the touch screen display from the left side to the right side;
• in response to detecting the first input gesture, selecting an application for display on a display screen from a set of two or more applications displayed on the display screen, wherein the two or more applications are secondary digital content displayed in the overlay above the primary video stream on the display screen;
• detecting a second input gesture by the user on the right side of the user interface on the touch interface device;
• in response to detecting the second input gesture, scrolling through a currently-displayed layer of the selected application displayed on the display screen, wherein scrolling through the currently-displayed layer takes place in an X-Y plane on the display screen;
• detecting a third input gesture by the user on the left side of the user interface on the touch interface device;
• and
• in response to detecting the third input gesture, scrolling between layers of the selected application in a simulated Z-space on the display device.
