Abstract
The present invention pertains to a broadcast network. The broadcast network comprises N transmit stations, with each transmit station being capable of transmitting a signal and N being an integer .gtoreq.1. There are also M receive stations, where M is an integer .gtoreq.2; I switching stages where I is an integer .gtoreq.0 and a broadcast hub. The broadcast hub and I switching stages are connected such that they are capable of linking the N transmit stations to the M receive stations so that any one of the N transmit stations can transmit a signal to L of the receive stations, where L is an integer and 2.ltoreq.L.ltoreq.M, but each receive stations can receive a signal from only one of the N transmit stations at any given time. The broadcast hub and switching stages link more than one of the N transmit stations to desired receive stations at any given time.
