In this paper, we present a novel distributed multiview video compression framework for surveillance purposes that employs a concealment based approach for the generation of the side information through the use of hybrid Key/Wyner- Ziv frames. Two multi-view coding structures are proposed in order to better exploit the inter-camera correlation present at the decoder. We additionally introduce a number of enhancements including use of spatio-temporal concealment for generating the side information on a MB basis, mode selection for switching between the two concealment approaches and for deciding how the correlation noise is estimated, local (MB wise) correlation noise estimation and modified B frame quantisation. The results presented indicate considerable improvement (up to 23%) compared to corresponding frame based schemes and improvements of up to 1.4 dB relative to an equivalent intra-view codec.
