APPARATUS FOR EFFICIENT STATISTICAL MULTIPLEXING OF VOICE AND DATA SIGNALS

摘要

A statistical multiplexer employing split band encoding in which each port has associated with it a sub-bank of filters (110F-130F) and a sub-bank of quantizers (110Q-130Q). The common equipment assigns the coding resource across all the ports rather than only within a single port. This equipment includes a power level measurement device (170) which is separately responsive to the output of each of the filters and provides an input to a signalling control and multiplexing equipment (180) and to a bit allocation device (171) which provides a control signal to each of the quantizers providing to each of them a bit allocation out of the pool of bit capacity for the entire multiplexer.
