Adaptive multiple description coding and transmission of uncompressed video over 60GHz networks

Abstract

While many cognitive radio (CR) techniques are developed to better utilize the allocated spectrum, the massive unlicensed bandwidth in the 60GHz band also provides great potential for supporting new bandwidth intensive applications. In this paper, we investigate the problem of streaming uncompressed High Definitio (HD) videos over 60GHz networks. We present an adaptive multiple description (MD) coding (MDC) technique based on Priority Encoding Transmission (PET) that exploits the different significanc of the pixel bits, and an interleaving based transmission scheme to combat the bursty losses due to blockage. A nonlinear integer programming problem is formulated and solved with a heuristic approach for determining the sub-optimal coding and transmission parameters. The proposed scheme is adaptive to the dynamic 60GHz link conditions for enhanced video quality. The performance of the proposed scheme is validated with simulations.
