Abstract: A system and method are provided for improving video encoding using content information. A three-dimensional (3D) modeling system produces an encoded video stream. The system includes a content engine, a renderer, and a video encoder. The renderer receives 3D model information from the content engine relating and to produces corresponding two-dimensional (2D) images. The video encoder receives the 2D images and produce a corresponding encoded video stream. The video encoder receives content information from the content engine, transforms the content information into encoder control information, and controls the video encoder using the encoder control information.

Abstract: A video frame compression system includes a rendering engine that provides a current video frame and current additional rendering information. Additionally, the video frame compression system includes a warping engine that generates a warped video frame, wherein the warped video frame is a transformation of a previous video frame that is based on the current additional rendering information. Further, the video frame compression system includes a video encoder that compresses the current video frame by using the warped video frame as a reference frame and separately compresses the current additional rendering information. Still further, the video frame compression system includes a packetizer that provides main and auxiliary data streams corresponding to the compressed current video frame and the compressed current additional rendering information, respectively. A video frame decompression system and methods of video frame compression and decompression are also provided.

Abstract: A system and method are provided for a 3D modeling system with which an encoded video stream is produced. The system includes a content engine, an encoder, and a fixed function engine. The fixed function engine receives content information from the content engine. The fixed function engine produces encoder information from the content information. The encoder uses the encoder information to produce an encoded video stream having at least one of a higher quality and a lower bandwidth than a video stream encoded without the encoder information.
