Abstract
An information delivery system which continuously provides sets of information which can be selected by a user. Digital data is encoded as analog signals which are used to amplitude modulate a carrier signal. A plurality of such modulated carrier signals, each constituting a subchannel, are mixed together to form a single channel which can be delivered to a user over a cable or otherwise. The data provided on each carrier in the channel constantly repeats itself so that the entire set of data on a particular carrier wll be available to a user in a relatively short time regardless of the time of access by the user. A first subchannel contains an index to the remaining subchannels to allow user selection of a particular set of information.
