Abstract: The embodiments of the present disclosure teach overlaying videos on a display device. The technique involves one or more buffers at input such as a first buffer (Primary Buffer) and an overlay buffer, a blitting module, a second buffer(Frame Buffer), and a display screen. The first buffer provides a first image data to the blitting module and the overlay buffer provides a second image data to the blitting module. The embodiments of the present disclosure demonstrate overlaying the second image on the first image with enhanced configurable functionality (like stretching, clipping, color keying, Alpha Blending and Raster Operation) if required, without modifying the Primary Buffer without the need of any overlay support in hardware.
