N2 - This work studies the error resilience of pixel-domain distributed video coding in noisy wireless transmission environment. Turbo codes are used to implement the DVC coder and the AWGN model is assumed for the transmission channel. The goal is to find out whether symbol based coding or bit-plane based coding is more robust against channel noise. We compare the two in the context of joint source-channel coding to ensure a high error resilience. First, we propose a framework to estimate the end-to-end distortion for these two schemes. Next, we allocate the rate between source coding and channel coding, aiming at a minimum end-to-end distortion. Then, we simulate the two schemes, setting the same bit budget for them, and compare their error resilience. Experimental results show that symbol based coding outperforms bit-plane based coding by up to 0.7 dB in PSNR of the decoded video.
