In this work we are integrating Direct Broadcast Satellite Systems (DBS) with Terrestrial networks to provide a hybrid and effective communication substrate lying between data resources and mobile user aplications. Smooth integration of these two media balances the need for rapid data dissemination to very large numbers of clients and on-demand interactive data services. We have developed algorithms which rapidly adapt the content of the broadcast based on the "misses" which result in explicit (on-demand) data requests.
