单向分布式视频编码(DVC)是DVC未触及的领域之一，当反馈通道不可用时必须采用它。因此，为了实现该目的，提出了使用并行Wyner-Ziv架构的单向分布式视频编码。仿真结果表明，在相同比特率和计算成本下，与没有反馈信道的传统 DVC 编解码器相比，所提出的编解码器可以获得高达 6.5 dB PSNR 增益
Unidirectional distributed video coding (DVC) is one of the untouched areas of DVC, which has to be necessarily employed when the feedback channel is not available. Thus, to serve that purpose, proposed is a unidirectional distributed video coding using a parallel Wyner-Ziv architecture. Simulation results show that up to 6.5 dB PSNR gain can be obtained with the proposed codec over the conventional DVC codec with no feedback channel at the same bit rate and the computational cost
