Abstract

A method and system for broadcasting at least one of a plurality of digitally encoded signals transmitted by a network provider to a plurality of user programmable devices disposed in a single environment. A remote interface unit is coupled to each of the user programmable devices for receiving a user programming from one of the plurality of user programmable devices. The user programming selects one of the plurality of compressed, digitally encoded signals. A common set-top transceiver is operatively connected to each of the remote interface units and the network provider including a first receiver for receiving the user programming from each of the remote interface units and a transmitter for transmitting the user programming to the network provider. The common set-top transceiver also includes a second receiver for receiving the selected one of the plurality of digitally encoded signals from the network provider and at least one video processing module for broadcasting the selected one of the plurality of digitally encoded signals to the plurality of user programmable devices based on the user programming.

Claims

1. For use with a network provider broadcasting multiple streams of compressed, digitally encoded signals, a method for transmitting the digitally encoded signals to a plurality of user programmable devices disposed in a single environment and coupled to a common set-top transceiver, the user programmable devices transmit and receive signals at a predetermined range of frequencies, the method comprising:

transmitting a user programming from each of the plurality of user programmable devices to the network provider via the common set-top transceiver at one of a plurality of frequencies within the predetermined range of frequencies, each of the user programmable device selecting the same or different one of the plurality of compressed, digitally encoded signals as each of the other user programmable devices;

receiving each of the selected ones of the plurality of digitally encoded signals from the network provider at the common set-top transceiver; and

transmitting each of the selected ones of the plurality of digitally encoded signals to each of the plurality of user programmable devices based on the user programming transmitted by each of the user programmable devices.

2. The method as recited in claim 1 wherein the predetermined range of frequencies correspond to a radio frequency spectrum.

3. The method as recited in claim 1 wherein the each of the plurality of frequencies correspond to a channel within the radio frequency spectrum.

4. The method as recited in claim 1 wherein transmitting each of the selected ones includes transmitting each of the selected ones of the plurality of digitally encoded signals to each of the plurality of user programmable devices based on the one of the plurality of frequencies.

5. The method as recited in claim 1 wherein each of the plurality of user programmable devices include a predetermined signal format and wherein the method further includes converting each of the selected ones of the plurality of digitally encoded signals into each of the corresponding predetermined signal formats.

6. The method as recited in claim 5 wherein the predetermined signal format is an analog signal format.

7. The method as recited in claim 6 wherein each of the user programming is an analog signal and wherein transmitting the user programming includes converting each of the analog signals into a corresponding digital signal.

8. The method as recited in claim 7 wherein transmitting the user programming includes modulating each of the user programming.

9. The method as recited in claim 8 wherein modulating each of the user programming is performed utilizing a radio frequency modulator.

10. The method as recited in claim 1 wherein the plurality of user programmable devices are television receivers.

11. The method as recited in claim 1 wherein the digitally encoded signals are video signals.

12. The method as recited in claim 1 wherein the digitally encoded signals are audio signals.

13. For use with a network provider broadcasting multiple streams of compressed, digitally encoded signals, a system for transmitting the digitally encoded signals to a plurality of user programmable devices disposed in a single environment, the system comprising:

remote interface unit coupled to each of the user programmable devices for transmitting a user programming from each of the plurality of user programmable devices, each of the user programmable device the same or different one of the plurality of compressed, digitally encoded signals as each of the other user programmable devices; and

a common set-top transceiver operatively connected to the network provider and to each of the remote interface units, the common set-top transceiver including;

a first receiver for receiving the user programming from each of the remote interface units;

a transmitter for transmitting each of the user programming to the network provider;

a second receiver for receiving each of the selected ones of the plurality of digitally encoded signals from the network provider; and

a plurality of video processing modules, each being assigned a corresponding virtual address, for transmitting each of the selected ones of the plurality of digitally encoded signals to each of the plurality of user programmable devices based on the user programming transmitted by each of the user programmable devices and the virtual address of the associated video processing module.

14. The system as recited in claim 13 wherein each of the plurality of user programmable devices transmit and receive signals at a predetermined range of frequencies and wherein each of the virtual addresses is a predetermined frequency within the predetermined range of frequencies.

15. The system as recited in claim 14 wherein the predetermined range of frequencies correspond to a radio frequency spectrum.

16. The system as recited in claim 15 wherein each of the virtual addresses is a channel within the radio frequency spectrum.

17. The system as recited in claim 14 wherein the at least one video processing module transmits each of the selected ones of the plurality of digitally encoded signals to each of the plurality of user programmable devices based on the one of the plurality of frequencies.

18. The system as recited in claim 13 wherein each of the plurality of user programmable devices include a predetermined signal format and wherein the common set-top transceiver further includes a converter for converting each of the selected ones of the plurality of digitally encoded signals into each of the corresponding predetermined signal formats.

19. The system as recited in claim 18 wherein the predetermined signal format is an analog signal format.

20. The system as recited in claim 19 wherein each of the user programming is an analog signal and wherein the first receiver includes a second converter for converting each of the analog signals into a corresponding digital signal.

21. The system as recited in claim 13 wherein the user programming is performed utilizing a remote control and wherein each of the remote interface units include an infrared receiver for receiving the user programming from the remote control.

22. The system as recited in claim 21 wherein each of the remote interface units include a modulator for modulating the user programming.

23. The system as recited in claim 22 wherein the modulator is a radio frequency modulator.

24. The system as recited in claim 13 wherein the plurality of user programmable devices are television receivers.

25. The system as recited in claim 13 wherein the digitally encoded signals are video signals.

26. The system as recited in claim 13 wherein the digitally encoded signals are audio signals.
