Abstract
An ATM/MPEG system receives individual MPEG programs of different constant bit rates from a plurality of servers. The individual programs are converted into ATM cells which are transmitted along an ATM network at a constant bit rate. The ATM cells are received and arranged into queues of the individual programs. A microprocessor prioritizes the queues based upon the bit rates of the MPEG programs. The queues are multiplexed to 16 VSB modulators based upon their priority assignments with the highest priority queues being sent to the modulators in preference to lower priority queues.
