摘要：
Techniques and tools for extended range variable length coding and decoding of differential motion vector information are described. For example, a video decoder determines whether or not to use an extended range variable length decoding mode. When the extended range variable length decoding mode is used, the decoder decodes a differential motion vector in the extended range variable length decoding mode. Otherwise, the decoder decodes the differential motion vector in a default range variable length decoding mode. A video encoder performs corresponding processing.
