Study for Distributed Video Coding Architectures

Distributed Video Coding (DVC) is mainly concerning for shifting high computational complexity at encoder of traditional video coding to the decoder. And DVC same with traditional video coding is required by hardware (VLSI) implement. Therefore, in this paper is for current DVC architectures, which are the typical case and easier to hardware (VLSI) implement, as an introduction. In the experimental results, this paper focus on the state-of-the-art DVC (DISCOVER) and the proposed Padding Block Based Distributed Video Coding (PB Based DVC) for comparison. In which the proposed DVC scheme shows better performance than DISCOVER in most video test sequences, and the decoder computational complexity lower than the DISCOVER over hundredfold.
