Abstract
System and method for use in a hybrid multispot satellite broadcasting system comprising at least one satellite (S; S1; S2) for multibeam broadcasting of beams in respective frequency bandwidths (F1; F2; F3), the system further comprising a plurality of terrestrial repeater (R1; R2; R3) for receiving, processing and re-transmitting said beams in a frequency bandwidth which is different from that of the bandwidth of the beam received. Each terrestrial repeater (R1; R2; R3) re-uses for terrestrial re-transmission a combination of bandwidths corresponding to different beams broadcast from said satellite to different beams.
