Abstract
A video compression system is provided. An encoder may encode video that is decoded by a decoder. The video may be made up of video frames. The decoder may generate approximated display frames for viewing on a display device based on corrected reference frames. The corrected reference frames at the decoder may be created based on approximated reference frames generated based on model state information and based on difference frames provided by the encoder. The encoder may create the difference frames by subtracting approximated reference frames from exact reference frames. The exact reference frames may be created based on a model of a three-dimensional virtual reality environment. The encoder may create the approximated reference frames based on corrected reference frames that are generated based on the difference reference frames.
