Abstract (en)

[origin: WO9815122A1] A communication system having programmable, addressable receivers that receive, store, process, and send digital and conventional video, audio and control signals for use in, among other things, a cable video network (9). Conventional audio and composite video and digital data signals are assembled into a single transmission by an automated production system. The transmission is delivered to the addressable receivers where the audio and video signals and some portion of the data may be selected and processed for re-transmission (114, 116, 118, 120, 98). The receivers may be addressed individually, in units or in groups for the purpose of receiving information on the basis of one or more pre-selected criteria.
