Abstract
The invention provides a system and method in which users may join a communication mode such that the multimedia content received by the user is closely matched to a predefined profile. The content may be transmitted by unicast, multicast or radio broadcast. Moreover, depending on an individual's request(s) and that of other users in a network, a user may switch between a radio broadcast, multicast and unicast to meet the user's preferences based on a profile. Profile data may include content type, transmission quality, cost considerations, etc. The two-way nature of the system and method also enable a user to request and receive information and complete transactions.
