Effective application of statistical multiplexing in advanced T-DMB System

This paper deals with an enhancement method on the simultaneous multimedia broadcast capacity over advanced T-DMB(AT-DMB) broadcast channel which is constrained by wireless capacity and service rate variation. Especially we focus on the statistical multiplexing, which can effectively mitigate the individual program's service rate variation without service quality degradation. In the current T-DMB system, as each program encoder produces a fixed data rate for each single program, a statistical multiplex could enhance each program's achievable video quality. This paper proposes an efficient statistical multiplexing scheme for an AT-DMB system and shows illustrative simulation results of the proposed method.
