Abstract: A broadcast material delivery architecture provides coordinated inclusion of supplemental materials with delivered broadcast material. A broadcaster broadcasts the broadcast materials to a plurality of users, the broadcast material being divided into a plurality of segments. Also broadcast is program data associated with the plurality of segments. A user terminal receives the broadcast material from the broadcaster and retrieving supplemental materials related to said plurality of segments of said broadcast material. To retrieve the supplemental materials, the program data are provided to a data server, which provides parameters for the supplemental materials to the user terminal. The user terminal uses the parameters to retrieve supplemental materials from one or more databases. The user terminal plays the supplemental materials in conjunction with the broadcast material.

Abstract: An insertion and encoder system monitors broadcasts from a first broadcasting system to determine the presence of segments that can be substituted in a second broadcast. In one embodiment, the system and method determines whether the first segment from the first broadcast had been sold for the second broadcasting system. In this example embodiment, if the first segment had not been sold for the second broadcasting system, it is substituted for a second segment. The system and method accesses an inventory of sold substitution segments and substitutes a sold segment for the unsold segment in real time. In one embodiment, sold advertisement segments are substituted for unsold advertisement segments that are broadcast to a wide audience over the Internet. Segments are selected in accordance with predefined criteria that can include user demographics and/or personal preferences.
