Abstract

Distributed video coding (DVC) is a potential solution for distributed video sensors in wireless visual sensor and machine-to-machine (M2M) networks. However, the error resilience schemes have not been fully investigated in literatures. In this paper, we propose several error resilience schemes for key frame transmission of DVC, including resending, refining, and hybrid modes. The resending mode asks the transmitters to resend the lost packets as automatic repeat-request, the refining mode conceals the corrupted key frames by temporal error concealment techniques with considering the characteristics of DVC, and the hybrid mode can adaptively select the better mode packet-by-packet with the proposed rate-distortion optimized mode decision. Experimental results show that the proposed schemes can achieve around 6-dB gain in PSNR compared with a baseline approach with intra error concealment. Furthermore, the hybrid mode can achieve 0.5-dB gain in PSNR for some sequences compared with the better one among the resending and refining modes.
