Abstract

Only one or only a few channels are sent at a time from circuitry located in a curbside box, via a link such as either a coaxial or a fiber cable, into a customer'"'"'s home TV set or personal computer. However, many more than a few channels are delivered to the curbside box, via a link such as a fiber or a coaxial cable, from a central office or a central bank of paid video-movies to be selected by the customers. Thus whereas the link from the central office or central bank is relatively broad-band (e.g. 500 MHz to 1,000 MHz), the cable from the curbside to the home (or any other kind of building) can be relatively narrow-band (e.g., 5 MHz to 50 MHz). The curbside box serves a multitude of homes--a separate (narrow-band) cable running to each home from the (same) curbside switch. Each channel can be a free radio or free TV channel, a stored or an on-line newspaper pay channel, or a pay TV channel, or a pay-per-view channel (i.e., the customer must give advance notice per view, and may begin viewing in the middle of a selected program, or may come in at the beginning of a selected program with a short delay, depending on the sender'"'"'s arrangement). Requests from each TV set in each home (e.g., initiated by means of a hand-held remote control infra-red sending device) can be sent to the curbside box from the home along a link such as a wire or along the same curbside-to-home cable itself. In addition, billing of customers can be accomplished by means of another link connecting a junction in the wire or in the curbside-to-home cable to one or more remote billing centers.

Claims

1. An interactive communication system including a curbside switch-box, the curbside switch-box comprising:

a converter which receives a plurality of channels from at least one first remote source;

a remote controller which receives a set of first signals from a set of first links and delivers controller signals to the converter in response to the set of first signals, the controller signals enabling the converter to select channels from the plurality of channels, wherein the converter delivers the selected channels via a set of second links to a plurality of viewing devices; and

a data storage and switching device which receives data from at least one second remote source, wherein the remote controller, in response to the set of first signals, enables the data storage and switching device and the converter to deliver selected data from the second remote source via the set of second links to the plurality of viewing devices.

2. The system of claim 1, wherein at least one of the first links is a pair of wires.

3. The system of claim 1, wherein at least one of the first links and one of the second links is a single coaxial cable.

4. The system of claim 1, wherein at least one of the second links is a coaxial cable.

5. The system of claim 1, wherein at least one of the first links and one of the second links is a single optical fiber.

6. The system of claim 1, further including a set of third links which connects the set of first links with a remote billing location.

7. The system of claim 1, further including a plurality of set-top boxes located in a plurality of locations, wherein each set-top box is connected to one of the first links and one of the second links.

8. The system of claim 1, wherein the remote controller, in response to the set of first signals, controls the data storage and switching device to switch between the at least one second remote source to deliver data to the converter from the selected second remote source.

9. The system of claim 1, wherein the data storage and switching device stores data received from the at least one second remote source and delivers at least some of the stored data to the converter in response to data controller signals developed by the remote controller in response to the set of first signals.

10. The system of claim 11, further including a set of third links connecting the set of first links with a remote billing location.

11. The system of claim 1, wherein the at least one first remote source is a cable television source.

12. The system of claim 1, wherein the at least one first remote source is a video bank.

13. The system of claim 1, wherein the at least one second remote source is an information source.

14. The system of claim 1, wherein the at least one second remote source is a data source.
