Abstract
Distributed video coding (DVC) is a relatively new video coding architecture originated from two fundamental theorems namely, Slepian–Wolf and Wyner–Ziv. Recent research developments have made DVC attractive for applications in the emerging domain of wireless video sensor networks (WVSNs). This paper reviews the state-of-the-art DVC architectures with a focus on understanding their opportunities and gaps in addressing the operational requirements and application needs of WVSNs.

Can Gray Code Improve the Performance of Distributed Video Coding

TL;DR: This paper comprehensively evaluates the performances of Gray code in different DVC schemes, such as feedback channel-based transform domain Wyner-Ziv (FC_TDWZ) video coding, parallel pixel domain Wyneyziv video codes, and encoder rate control-based TDWZ (ERC_TD WZ).

Side information hybrid generation based on improved motion vector field

TL;DR: In this paper, a side information hybrid generation algorithm based on an improvement model for the motion vector field is proposed, where the side information frame to be generated for the current Wyner-Ziv frame is divided into easy to estimate and difficult to estimate macroblocks.

Low-Density Parity-Check Codes

TL;DR: A simple but nonoptimum decoding scheme operating directly from the channel a posteriori probabilities is described and the probability of error using this decoder on a binary symmetric channel is shown to decrease at least exponentially with a root of the block length.
