Error Protection of 3D Wavelet Video Streaming Using Wyner-Ziv Video Coding for Lossy Network Transmission
In this paper we propose a novel method that is motivated by distributed source coding to correct the errors of significant sections in 3D wavelet video streaming. Extra information is generated by Wyner-Ziv codec and is sent to the decoder. While errors occur, the relevant parts in the same frames from EZBC decoder are used as side information to decode the Wyner-Ziv bits to produce a refined replacement of the corrupted ones. Finally the rest parts of these frames are combined with refined parts from the Wyner-Ziv description to yield a correct sequence. We present the simulation results to demonstrate that our scheme can achieve significant gains in error-resilient performance compared with Forward Error Correction scheme.
