Abstract

In recent years, with emerging applications such as wireless video surveillance, multimedia sensor networks, disposable video cameras, medical applications and mobile camera phones, the traditional video coding architecture is being challenged. For these emerging applications, Distributed Video Coding (DVC) seems to be able to offer efficient and low-complexity encoding video compression. In this paper, we present a novel transform domain distributed video coding algorithm based on Turbo Trellis Coded Modulation (TTCM). As in the conventional turbo based Wyner-Ziv encoder, transform quantized coefficients are applied to the TTCM encoder and parity bits are generated from both constituent encoders. However, TTCM symbols are not generated at the encoder since they are not sent to the decoder. Parity bits produced by the TTCM encoder are stored in a buffer and transmitted to the decoder upon request. TTCM symbols are generated at the decoder and these symbols are passed to the TTCM decoder for demodulation. Experimental results show that significant rate-distortion (RD) gains compared to the state-of-the-art results available in the literature can be obtained.
