Abstract

Systems and methods are disclosed for providing television services and/or presentations to a plurality of televisions located at a customer premises. One such method, among others, includes: receiving by a set-top terminal (STT) located at a customer premises, via a transmission link that is coupled to the STT, a television service that was transmitted from a remote location, and transmitting the television service by the STT, via the transmission link, to a television that is located at the customer premises.

Claims

1. A method for providing television services, comprising the steps of:

receiving by a first set-top terminal (STT) located at a customer premises, via a first transmission link that is coupled to the STT, a first television service that was transmitted from a headend; and

transmitting the first television service by the STT, via the first transmission link, to a first television that is located at the customer premises.

2. The method of claim 1, further comprising:

transmitting a second television service by the STT, via a second transmission link, to a second television that is located at the customer premises.

3. The method of claim 1, further comprising:

prior to transmitting the first television service by the STT, receiving by the STT a request for the first television service from a remote control device that is configured to control the first television.

4. The method of claim 1, wherein the first television service is transmitted at a frequency that is above the frequency band of a broadband signal that is received by the STT from the headend.

5. The method of claim 1, wherein the first television service is transmitted at a frequency that is above 860 MHz.

6. The method of claim 1, wherein the first television service is transmitted at a frequency that is substantially equal to a frequency of an Ultra-high frequency (UHF) channel that is not being used to transmit a television service from the headend to the STT.

7. The method of claim 1, further comprising:

receiving the first television service by a splitter module from the STT.

8. The method of claim 7, further comprising:

passing the first television service by the splitter module to a radio frequency (RF) converter module that is configured to convert the frequency of the first television service to a lower frequency that corresponds to a predetermined television channel, and that is configured to transmit the first television service to the first television.

9. The method of claim 7, further comprising:

converting the frequency of the first television service by the splitter module to a lower frequency that corresponds to a predetermined television channel.

10. The method of claim 9, further comprising:

passing the first television service by the splitter module to the first television.

11. A set-top terminal (STT) comprising:

a tuner for extracting a first television service from a broadband signal that is received by the STT via a first transmission link that is coupled to the STT;

an ultra-high-frequency (UHF) transmitter; and

a processor that is programmed to cause the UHF transmitter to transmit the first television service via the first transmission link to a first television in response to the STT receiving from a first remote control device user input requesting the first television service.

12. The STT of claim 11, wherein the first television service is transmitted by the UHF transmitter to the first television at a frequency that is above the frequency band of the broadband signal that is received by the STT.

13. The STT of claim 11, wherein the first television service is transmitted by the UHF transmitter to the first television at a frequency corresponding to a channel that is not being used to transmit a television service from a headend to the STT.

14. The STT of claim 11, wherein the first television service is transmitted by the UHF transmitter to the first television at a frequency that is above 860 MHz.

15. The STT of claim 11, further comprising:

an output system for outputting a second television service via a second transmission link to a second television.

16. The STT of claim 15, wherein the processor is also programmed to cause the output system to transmit the second television service via the second transmission link to a second television in response to the STT receiving from a second remote control device user input requesting the second television service.

17. A system comprising:

a set-top terminal including,

a tuner for extracting a first television service from a broadband signal that is received by the STT via a first transmission link that is coupled to the STT,

an ultra-high-frequency (UHF) transmitter, and

a processor that is programmed to cause the UHF transmitter to transmit the first television service via the first transmission link to a first television in response to the STT receiving from a first remote control device user input requesting the first television service; and

a splitter module that is configured to receive the first television service from the STT and to pass the television service to the first television.

18. The system of claim 17, wherein the splitter module is also configured to convert the frequency of the first television service to a frequency corresponding to a predetermined television channel.

19. The system of claim 17, further comprising:

a radio frequency (RF) converter module that is configured to receive the first television service from the splitter module and to transmit the first television service to the television at a frequency corresponding to a predetermined television channel.

20. A system comprising:

a first set-top terminal (STT) including,

a first tuner that is configured to extract video data from a broadband signal that is received by the first STT via a first transmission link that is coupled to the first STT,

a storage device that is configured to store the video data;

an ultra-high-frequency (UHF) transmitter, and

a processor that is programmed to cause the UHF transmitter to transmit the video data via the first transmission link to a second STT in response to the first STT receiving, from a first remote control device, user input requesting the video data; and

a splitter module that is configured to receive the video data from the first STT and to pass the video data to the second STT.

21. The system of claim 20, wherein the user input comprises an infra red (IR) signal.

22. The system of claim 21, further comprising:

an IR signal receiver that is configured to receive the user input, to encode the user input using on-off keying (OOK), and to transmit the OOK encoded user input to the first STT.

23. The system of claim 20, wherein the splitter module is also configured to convert the frequency of the video data to a frequency corresponding to a predetermined television channel.

24. The system of claim 20, further comprising:

a radio frequency (RF) converter module that is configured to receive the video data from the splitter module and to transmit the video data to the television at a frequency corresponding to a predetermined television channel.
