Region of interest selection, decoding and rendering of picture-in-picture window

A computing device, comprising:

• a memory device resident in the computing device;
• and
• a processor disposed in communication with the memory device, the processor configured to:
• display a secondary video signal for a secondary program;
• receive a boundary that defines a Region of Interest (ROI) on the secondary video signal;
• extract a portion of the secondary video signal, the portion corresponding to the ROI;
• display a primary video signal for a primary program in a main window;
• and
• display the portion of the secondary video signal in the main window, wherein the portion of the secondary video signal overlays the primary video signal.

A non-transitory computer-readable medium, comprising computer-executable instructions that, when executed on a computing device, perform steps of:

• displaying a secondary video signal for a secondary program;
• receiving a boundary that defines a Region of Interest (ROI) on the secondary video signal;
• extracting a portion of the secondary video signal, the portion corresponding to the ROI;
• displaying a primary video signal for a primary program in a main window;
• and
• displaying the portion of the secondary video signal in the main window, wherein the portion of the secondary video signal overlays the primary video signal.
