Dynamic Mosaic for Creation of Video Rich User Interfaces

Systems and methods for delivering video content for use in video rich user interfaces are disclosed. A mosaic channel may be generated, comprised of multiple video tiles each located at a different position within the mosaic channel, and transmitted to a receiving device. Audio for each video tile may also be provided. The receiving device may, using a 3D graphics engine (e.g., OpenGL), generate a video rich user interface navigable by a user to preview any of the different videos or other content included within the mosaic channel. The content included within the mosaic channel may be altered as the user is navigating the video rich user interface so that the user can continuously preview different content.
