An audio/video distribution system for a multiple dwelling unit such as an apartment building provides programming which is selectable by a subscriber through the interactive use of on-screen menus. Programming and services are supplied from a headend over a distribution network to individual apartments. The distribution network includes an interdiction field unit associated with each of a group of apartments. The interdiction field unit normally interdicts those channels capable of carrying video on demand movies, interactive video games, and interactive services. When a subscriber wishes to order a movie, video game, or other service through interactive on-screen menus provided from the headend to the apartment, the headend instructs the interdiction field unit associated with the subscriber's apartment to de-interdict a channel. Selections made through a remote control to a subscriber terminal in the apartment are supplied to the headend over the distribution system. The channel remains deinterdicted during the playing of a movie, video game, or interactive service selected by the subscriber, based upon the signals received from the subscriber terminal during the interactive on-screen menu session. |
