Abstract
A mechanism for memory reduction in picture-in-picture video generation is disclosed. A method of embodiments of the invention includes receiving, from a transmitting device, a plurality of video streams at a receiving device coupled to the transmitting device, wherein a first video stream of the plurality of video streams is designated to be displayed as a main video and one or more other video streams of the plurality of video streams are designated to be displayed as one or more sub videos to the main video. The method further includes transforming the one or more other video streams into the one or more sub videos, temporarily holding the one or more sub videos in a compressed frame buffer, and merging, via pixel replacement, the main video and the one or more sub videos into a final video image capable of being displayed on a single screen utilizing a display device, wherein pixel replacement is performed such that the one or more sub videos occupy one or more sections of pixels of screen space pixels occupied by the main video.
