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 lowerresolution or quality bitstreams into higher resolution or quality bitstreams, scalable coding is a new approach to represent and prioritize data.

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.
