Abstract:

A method of transmitting real time digital video, audio and composite signals along existing delivery circuit and transmission pathways that takes advantage of unused bandwidth in existing transmission spectrums and circuit pathways. The invention permits the delivery of messages, commands and data files which may be presented later to the consumer at a predefined time and place and in a predefined format allowing the transmission of CD quality digital sound, digital video and bitmap files to a consumer, group of consumers or consumer population. The method and apparatus described transmits information and data to the consumer in a non real-time background mode which may be stored in a local repository for future presentation. Presentation parameters are transmitted either concurrently with or subsequently to information and data. The method may be employed on a wide variety of platforms including television, cable, satellite, telephone networks, private and public data networks and dedicated lines.
