A system is disclosed for delivering audio and/or video signals to users in connection with the provision of interactive television services. Various sources of such signals are connected to a digital network, such as a packet network. Also connected to such network are control and application processors and interfaces to distribution arrangements such as cable television systems and telephone subscriber loops. Each user has a signal converter for receiving a digital signal from the distribution arrangement, converting such signal for viewing on a conventional television receiver and transmitting control packets to other elements of the system. The signal sources can include a data cache for storing recorded video and audio materials, a broadcast source for receiving broadcast signals, apparatus for composing multimedia signals from multiple sources and apparatus for running games. The various elements of the system can be situated at different geographical locations and operated by the control and/or application processors under software control to provide a variety of interactive television services.

An interactive system for delivering information programs comprising data packets to users over a cable television distribution system, the data packets being transmitted in television transmissions of the cable television distribution system in response to user commands received over the cable television distribution system, the interactive system comprising: a packetized network; network routing control coupled to the packetized network for assigning communications paths through the packetized network and enabling transmission of data packets and control packets on the paths through the packetized network; at least one information source coupled to the packetized network for providing at least data packets to the packetized network; a cable television distribution system interface coupled between the packetized network and the cable television distribution system for providing user commands from the cable television distribution system to the packetized network and providing at least data packets from the packetized network to the cable television distribution system; and a controller coupled to the packetized network for receiving user commands from the packetized network and transmitting control packets to the at least one information source and the cable television distribution system interface, the controller, in response to received user commands, instructing the network routing control to assign a path in the packetized network, instructing the at least one information source to provide data packet on the assigned path through the packetized network, and instructing the cable television distribution system interface to receive at least the data packets placed on the assigned path of the packetized network and modulate the received data packets in the television transmissions to the user.
