Abstract:
Method and apparatus for allowing viewers to control broadcast programming content includes a programming uplink facility, a satellite relay and a plurality of receiver stations. The receiver stations each include a satellite dish antenna, a low-noise-block (LNB) converter coupled to the antenna, an integrated receiver/decoder (IRD) coupled to a the LNB, and a conventional television display coupled to the IRD. In addition to primary programming, the uplink facility broadcasts special subordinate programming that is received by the IRD and made available for display on viewer command. The viewer can control programming content by instructing the IRD to either switch from the primary programming to the special subordinate programming, or to incorporate the special subordinate programming into the primary programming content. Preferably, the special subordinate programming has a direct relation to the substantive content of the program.
