Abstract
A receiver is provided for an information system that provides selected information to individual users. A high speed digital program signal is broadcast and contains program data that begins at a reference time and is repeated at set intervals. An index signal that contains the receiver's identifier associated with the reference time and interval information is also broadcast. The receiver monitors the index signal for its identifier. When the receiver detects its identifier, the receiver downloads the time and tuning information. The receiver then uses the time and tuning information to receive, download, and store the user's selected program. In some embodiments a transceiver replaces the receiver to allow the user to make remote program requests.
