Abstract

A scalable bitstream syntax currently is used to realize the scalable video requirement. Compared with non-scalable video decoder, a much more complex video decoder is need to decode scalable bitstreams. However, it is considered that a video decoder should implement as simple as possible to play some quality video which users want. From this view point, a scalable video coding scheme by updatable bitstream is proposed to realize the scalability without scalable video decoder. In this paper, we pay attention to spatial updatable scalability and explain this algorithm. Finally, our proposed method is evaluated from simulation.
