An entertainment head-end provides broadcast programming, video-on demand services, and HTML-based interactive programming through a distribution network to client terminals in subscribers' homes. A number of different features are provided, including novel user interfaces, enhanced video-on-demand controls, a variety of interactive services (personalized news, jukebox, games, celebrity chat), and techniques that combine to provide user experiences evocative of conventional television.
