Extending prediction modes and performance of video codecs |
| 摘要 |
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. |

1. A video frame compression system, comprising:
a rendering engine that provides a current video frame and current additional rendering information that differs from the current video frame; 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; and 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. |
