Abstract
Systems and methods for encoding/decoding a video stream. Animated talking heads are coded using partial offline encoding, multiple video streams, and multiple reference frames. The content of a face animation video that is known beforehand is encoded offline and the remaining content is encoded online and included in the video stream. To reduce bit rate, a server can stream multiple video sequences to the client and the video sequences are stored in the client's frame store. The server sends instructions to play a particular video sequence instead of streaming the particular video sequence. Multiple video streams can also be streamed to the client. Positional data and blending data are also sent to properly position one video stream relative to another video stream and to blend one video stream into another video stream.
