Abstract
The invention refers to a system for distributing data from a transmission station to a plurality of user stations over a transmission channel having a predetermined bandwidth. In order to provide internet services to the end user via a single direct-to-home satellite transmission channel, the transmission channel comprises a contents channel and an announcement channel, wherein the transmission station transmits over the contents channel a data subset within a certain period and transmits over the announcement channel an index of future data subsets to be transmitted, and wherein a user profile is stored in each user station characterizing the relative importance of topics of interest to the user and wherein the user station downloads data subsets from the transmission channel in accordance with the quality of matching between the index of the announcement channel and the user profile.
