Because of differential coding used in standard video compression algorithms to exploit temporal correlation in adjacent frames for coding gain, a frame lost in network will cause error propagation in subsequent frames at the decoder. Previously proposed Distributed Source Coding (DSC) frames can be periodically inserted to halt this error propagation by overcoming the uncertainty at encoder of which frames will be correctly received at decoder, without resorting to large intra-coded I-frames. In this paper, the authors propose a unified DSC frame construction for IMVS, so that the encoder can overcome both types of uncertainty in a coding-efficient manner; i.e., halt error propagation in differentially coded multi-view video and facilitate periodic interactive view switching at the same time.
