In this paper we advocate a multi-resolution mechanism for redundant information generation and transmission with low overheads in bit-rate, in order to enable reliable video communication over challenging lossy networks with low latency. Our previous work entitled RECAP, transmitted a low resolution redundant version of a parent video stream, in order to achieve effective concealment of isolated...
Most of the Wyner-Ziv (WZ) video coding schemes in literature model the correlation noise (CN) between original frame and side information (SI) by a given distribution whose parameters are estimated in an offline process. In this paper, an online CN modeling algorithm is proposed towards a more practical WZ-based error resilient video coding (WZ-ERVC). In ERVC scenario, the side-information is typically...
Current models in Wyner-Ziv video coding consider the temporal correlation noise to be side-information independent (SII). This paper goes beyond this assumption and proposes a novel model, of which the parameters are side-information dependent (SID). The proposed model is experimentally validated showing remarkable accuracy improvement over the conventional SII model. Moreover, a novel SID technique...
