Due to the growth and success of the Internet and wireless communication, as well as increasing demand for multimedia services, streaming media over the Internet and wireless channels has drawn tremendous attention. Scalable coding is a both effective and efficient solution for this purpose. By embedding lower resolution or quality bitstreams into higher resolution or quality bitstreams, scalable coding is a new approach to represent and prioritize data. In this book, a fully scalable video coding algorithm with combined temporal, spatial and quality scalability is designed. Since subband/wavelet coding inherently provides multi-resolution representation, a motion compensated 3D (spatiotemporal) subband/wavelet transform is utilized to realize temporal and spatial scalability. Motion compensated temporal filtering (MCTF) plays an essential role in this 3D transform. It influences coding efficiency and also temporal scalability. In this book, sub-pixel accurate MCTF with lifting scheme is also presented.
