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.
