The differences between distributed video coding and conventional video coding paradigm followed by application scenarios of them are presented.Theoretical foundations and main coding frameworks of the DVC are described.Questions and solutions proposed recently of several key techniques in DVC such as Wyner-Ziv coder,side information construction and modeling of the virtual "correlation channel" are analyzed.Finally,the research directions of the DVC and some other promising application scenarios of the distributed coding are discussed.
