US Patent 10546424 Layered content delivery for virtual and augmented reality experiences

A virtual reality or augmented reality experience of a scene may be presented to a viewer using layered data retrieval and/or processing. A first layer of a video stream may be retrieved, and a first viewer position and/or orientation may be received. The first layer may be processed to generate first viewpoint video of the scene from a first virtual viewpoint corresponding to the first viewer position and/or orientation. The first viewpoint video may be displayed for the viewer. Then, a second layer of the video stream may be retrieved, and a second viewer position and/or orientation may be received. The second layer may be processed to generate second viewpoint video of the scene from a second virtual viewpoint corresponding to the second viewer position and/or orientation, with higher quality than the first viewpoint video. The second viewpoint video may be displayed for the viewer.
