Seamless switching of scalable video bitstreams |
摘要 |
In accordance with certain aspects of the present invention, methods and apparatuses are provided according to a seamless bitstream switching scheme. The seamless switching scheme can be used with scalable video bitstreams, and can take advantage of both the high coding efficiency of non-scalable bitstreams and the flexibility of scalable bitstreams. Small bandwidth fluctuations can be accommodated by the scalability of the bitstreams, while large bandwidth fluctuations can be tolerated by switching among scalable bitstreams. The flexible and effective scheme for seamless switching among scalable bitstreams significantly improves the efficiency of scalable video coding over a broad bit rate range.
