Abstract:
A satellite broadcasting system for communication between a satellite hub and a range of ground stations in which a set having a predetermined number of modulation-codings (MODCODs) is available for data transmission from the satellite hub to the ground stations. Each MODCOD in use in the hub requires additional hub resources, and the system uses a MODCOD limiter for limiting the number of MODCODs in operation at a given time to a subset smaller than said predetermined number of MODCODS, thereby reducing overall resource usage.
