ABSTRACT

This chapter focuses on applying distributed source coding principles to video compression, covering three areas of distributed video coding, namely, Witsenhausen–Wyner video coding, layered Wyner–Ziv (WZ) video coding, and multiterminal (MT) video coding. It highlights triumphs achieved so far in distributed video coding and pointing out future directions. In MT video coding for video sensor network applications, since the encoders are not allowed to communicate with each other, the use of distributed source coding is a must. The chapter discusses latest MT video coding setup where a low-resolution depth camera is employed to assist side information generation at the decoder. The demand for distributed video coding applications and recent progresses made on Search window (SW) and WZ code designs have fueled much initial excitements and possibly hype about the topic, leading to some confusion or even disappointment.
