摘要：
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 [1] with no feedback channel at the same bit rate and the computational cost.
