Abstract
Abstract An interactive television information system coupled to a cable television system having a headend for supplying information services and an information service distribution network for delivering information services to subscriber televisions. Each subscriber television is associated with a home interface controller. The home interface controllers receive the television information signals and include a data transceiver for data communications. A subscriber selection device associated with a home interface controller permits subscriber interaction through the data transceiver with an assigned interactive controller from a plurality of interactive controllers. The assigned interactive controller is in communication with the information sources and in television communication with its assigned home interface controller. Selection of an information source nay be made through channel selection of an apparent channel from any of a first group of apparent channels and a second group of apparent channels. Different information services on different apparent channels from the first group of apparent channels are provided to a given home interface controller via the same television information signal as the subscriber changes channel selection from one of the apparent channels in the first group of apparent channels to another apparent channel in the first group of apparent channels. To receive apparent channels from the second group of apparent channels, a home interface controller simply selects the television information signal at its input corresponding to the selected channel.
