New Approaches to Statistical Multiplexing for Perceptual Audio Coders Used in Multi-Program Audio Broadcasting
In the case of multi-program audio broadcasting or transmission joint encoding is an attractive proposition. It has previously been reported that the conventional joint encoding benefits conventional perceptual audio coders in this scenarios. However, previous attempts to such statistical multiplexing have focused primarily on joint bit allocation. Here we show that such an approach is not sufficient to realize the promise of statistical multiplexing. Rather a successful strategy has two essential ingredients including a highly accurate psychoacoustic model and a coordination mechanism that goes beyond joint allocation. We describe methods to achieve these objectives and also present objective and subjective coding results.
