Abstract

A method is disclosed for delivering broadband video data to an end user device comprising transmitting broadband video data via a radio frequency transmitter to a home radio frequency receiver located at a residential power transformer providing electrical power to a home; coupling the broadband video data from the home radio frequency receiver to a first modem onto a copper power line electrically coupled to the residential power transformer; receiving the broadband data on a second modem from the copper power line; and sending from the second modem, different portions of the broadband data to each of a plurality of end user devices in the home. A system and computer program for performing the method are disclosed.

First claim

What is claimed is:

1. A method for delivering broadband video data to an end user device comprising:
receiving, by a processing system including a processor, broadband video data from a home radio frequency receiver that obtains the broadband video data from a radio frequency transmitter, wherein the home radio frequency receiver located at a residential power transformer that provides electrical power to a home; and
transmitting, by the processing system, the broadband video data to a second modem from copper power line electrically coupled to the residential power transformer to enable the second modem to send different portions of the broadband video data to each of a plurality of end user devices in the home.

2. The method of claim 1 , wherein the second modem sends the broadband video data to the end user device in a unicast.

3. The method of claim 1 , wherein the broadband video data is multicast from the second modem to the plurality of end user devices and wherein a plurality of RF signals comprises a band of RF frequencies and wherein a first subset of the band of RF frequencies is associated with a first end user device and a second subset of the band of RF frequencies is associated with a second end user device, wherein the first subset of the band of RF frequencies and the second subset of the band of RF frequencies do not overlap.

4. The method of claim 1 , further comprising: transmitting, by the processing system, a first plurality of RF signals to a first plurality of RF receivers in a first local region and transmitting a second plurality of RF signals to a second plurality of RF receivers in a second local region, wherein the first plurality of RF signals and the second plurality of RF signals do not interfere with each other in their respective local regions.

5. The method of claim 1 , wherein
the broadband video data is received as an optical signal by the radio frequency transmitter and wherein the radio frequency transmitter has converted the optical signal using a uni-traveling carrier photodiode.

6. The method of claim 3 , wherein the first subset of the band of RF frequencies are encrypted using a first encryption key associated with the first end user device and the second subset of the band of RF frequencies are encrypted using a second encryption key associated with the second end user device.

7. The method of claim 4 , wherein the first plurality of RF signals and second plurality of RF signals share a same frequency band.

8. The method of claim 5 , wherein a phase of a carrier signal is used for one of link management and enhanced power when link degradation occurs.

9. A method, comprising:
receiving, by a processing system including a processor, broadband video data from a home radio frequency receiver that obtains the broadband video data from a radio frequency transmitter, wherein the home radio frequency receiver located at a residential power transformer that provides electrical power to a home; and
transmitting, by the processing system, the broadband video data to a second modem from a copper power line to enable the second modem to send different portions of the broadband video data to each of a plurality of end user devices in the home, wherein a received radio frequency signal carrying the broadband video data is converted from an optical signal by sampling the received signal using electro optic sampling.

10. The method of claim 9 , wherein the second modem sends the broadband video data to an end user device in a unicast.

11. The method of claim 9 , wherein the broadband video data is multicast from the second modem to the plurality of end user devices and wherein a plurality of RF signals comprises a band of RF frequencies and wherein a first subset of the band of RF frequencies is associated with a first end user device and a second subset of the band of RF frequencies is associated with a second end user device, wherein the first subset of the band of RF frequencies and the second subset of the band of RF frequencies do not overlap.

12. The method of claim 9 , further comprising: transmitting, by the processing system, a first plurality of RF signals to a first plurality of RF receivers in a first local region and transmitting a second plurality of RF signals to a second plurality of RF receivers in a second local region, wherein the first plurality of RF signals and the second plurality of RF signals do not interfere with each other in their respective local regions.

13. The method of claim 11 , wherein the first subset of the band of RF frequencies are encrypted using a first encryption key associated with the first end user device and the second subset of the band of RF frequencies are encrypted using a second encryption key associated with the second end user device.

14. The method of claim 13 , wherein a first plurality of RF signals and a second plurality of RF signals share a same frequency band.

15. A method comprising
receiving, by a processing system including a processor, broadband video data from a home radio frequency receiver that obtains the broadband video data from a radio frequency transmitter, wherein the home radio frequency receiver located at a residential power transformer that provides electrical power to a home, and, wherein the radio frequency transmitter is placed in a location selected from the group consisting of an electric power distribution substation, a residence and a triple play network node; and
transmitting, by the processing system, the broadband video data to a second modem from a copper power line to enable the second modem to send different portions of the broadband video data to each of a plurality of end user devices in the home.

16. The method of claim 15 , wherein the broadband video data is received as an optical signal by the radio frequency transmitter and wherein the radio frequency transmitter has converted the optical signal using a uni-traveling carrier photodiode.

17. The method of claim 15 , wherein the second modem sends the broadband video data to an end user device in a unicast.

18. The method of claim 15 , wherein the broadband video data is multicast from the second modem to the plurality of end user devices and wherein a plurality of RF signals comprises a band of RF frequencies and wherein a first subset of the band of RF frequencies is associated with a first end user device and a second subset of the band of RF frequencies is associated with a second end user device, wherein the first subset of the band of RF frequencies and the second subset of the band of RF frequencies do not overlap.

19. The method of claim 15 , further comprising: transmitting, by the processing system, a first plurality of RF signals to a first plurality of RF receivers in a first local region and transmitting a second plurality of RF signals to a second plurality of RF receivers in a second local region, wherein the first plurality of RF signals and the second plurality of RF signals do not interfere with each other in their respective local regions.

20. The method of claim 16 , wherein a phase of a carrier signal is used for one of link management and enhanced power when link degradation occurs.
