Abstract

A satellite payload architecture for interactive data distribution and broadcasting services preferably for use in the emerging EHF (20-60 GHz) frequency bands. The system allows many individual service-program providers to transmit their service-program data to the satellite, on a bandwidth-on-demand and as-needed basis, directly from their premises through low-power, low-cost broadcast satellite terminals. The satellite payload utilizes high-gain spot beams for low-cost uplinking, digital regeneration and multiplexing of the individual received service-program data into MPEG transport streams, and broadcasting these in a DVB-compatible format via full-area broadcast beams to very small, low-cost end-user satellite terminals. All end-user satellite terminals are also equipped with transmit capability of a reverse-channel in support of interactivity-communications and network signaling/control functions. The proposed system will provide low-cost interactive data distribution and broadcasting services to thousands of small and large content-providers to reach their target customers.
