Abstract

In this paper, we present an optimal solution to the problem of error control in layered and replicated media systems satisfying real-time delay constraints. In doing so, we rely on an a priori estimate of loss along with a hybrid proactive FEC-ARQ scheme to statistically guarantee the quality of service for receivers. Our optimal layered media multicast control (LMMC) solution to a formulation of the error control problem analytically determines the redundancy assignment of individual groups associated with a layered media system minimizing a cost metric defined over wasted bandwidth of redundancy.
