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.

Abstract: Embodiments of the invention are generally directed to transmission and handling of three-dimensional video content. An embodiment of a method includes receiving a multimedia data stream including video data utilizing an interface protocol and determining that the received video data includes three-dimensional (3D) video data, where each frame of the video data includes a first vertical synchronization (Vsync) signal prior to an active data region, the active data region including a first data region and a second data region. The method further includes converting the 3D video data from a 3D data format to a two-dimensional (2D) video format, where converting the 3D video data includes identifying a region between the first data region and the second data region, inserting a second Vsync signal between the first data region and the second data region, and providing an identifier to distinguish between the first data region and the second data region.
