Abstract

A content distribution system and method receives data from a data source and identifies at least one unused channel in the received data. The unused channel is filtered and identified as an available content transmission channel. Content is then received from a content source and encoded to generate encoded content. The encoded content is modulated to generate modulated content, which is distributed within a distribution environment using the available content transmission channel.

Claims

1. A method comprising:

receiving data from a cable service provider;

identifying at least one unused channel in the cable network;

filtering the unused channel;

mapping the unused channel as an available content transmission channel;

receiving content from a content source;

encoding the received content to generate encoded content;

modulating the encoded content to generate modulated content; and

distributing the modulated content within a distribution environment using the available content transmission channel.

2. The method of claim 1, wherein encoding the received content includes encoding the received content in a manner that allows existing display devices to decode the encoded content.

3. The method of claim 1, wherein modulating the encoded content includes modulating the encoded content in a manner that allows existing display devices to tune the modulated content.

4. The method of claim 1, wherein distributing the modulated content using the available content transmission channel includes distributing the modulated content in a limited geographic area.

5. The method of claim 1, wherein the content is video content.

6. The method of claim 1, wherein the content is high definition television content.

7. The method of claim 1 wherein encoding the received content includes converting the received content into an analog standard definition television signal.

8. The method of claim 1, wherein modulating the encoded content includes modulating the encoded content using Quadrature Amplitude Modulation.

9. The method of claim 1, wherein identifying at least one unused channel in the cable network includes identifying at least one undesired channel in the cable network.

10. The method of claim 1, wherein the modulated content is distributed via existing cable transmission wires in the distribution environment.

11. The method of claim 1, wherein the modulated content is distributed wirelessly within the distribution environment.

12. The method of claim 1, further comprising filtering undesired channels.

13. A method comprising:

receiving data from a content service provider;

identifying any unused channels associated with the data received from the content service provider;

identifying any undesired channels;

decoding the data received from the content service provider to generate decoded data;

encoding the decoded data by removing data associated with unused channels and data associated with undesired channels to generate encoded data; and

distributing the encoded data within a distribution environment.

14. The method of claim 13, wherein the encoded data is distributed within the distribution environment via existing cable transmission wires in the distribution environment.

15. The method of claim 13, wherein the encoded data is distributed wirelessly within the distribution environment.

16. The method of claim 13, wherein the encoded data is distributed within the distribution environment via existing transmission wires in the distribution environment and via wireless transmission.

17. The method of claim 13, wherein decoding the data includes demodulating the data received from the content service provider to generate demodulated data and demultiplexing the demodulated data.

18. The method of claim 13, wherein encoding the data includes re-multiplexing the decoded data to generate re-multiplexed data and modulating the re-multiplexed data.

19. An apparatus comprising:

a receiving device configured to receive data from a content service provider and to identify a plurality of unused channels in the received data, the receiving device further configured to filter the unused channels and map the unused channels as available content transmission channels;

a first distribution device coupled to the receiving device and configured to receive available content transmission channel information from the receiving device, the first distribution device further configured to distribute content received from a first content source to at least one display device via a first available content transmission channel; and

a second distribution device coupled to the receiving device and configured to receive available content transmission channel information from the receiving device, the second distribution device further configured to distribute content received from a second content source to at least one display device via a second available content transmission channel.

20. The apparatus of claim 19, further comprising a recording device coupled to the receiving device and configured to record content for future distribution via an available content transmission channel.

21. The apparatus of claim 19, wherein the receiving device is further configured to distribute a listing of the available content transmission channels to the first distribution device and the second distribution device.

22. The apparatus of claim 19, wherein the first distribution device is further configured to wirelessly distribute content received from the first content source to a display device.

23. The apparatus of claim 19, wherein the first distribution device is further configured to distribute content received from the first content source to a display device via existing physical transmission wires.

24. The apparatus of claim 19, wherein the receiving device is further configured to filter an undesired channel from the received data and map the undesired channel as another available content transmission channel.

25. The apparatus of claim 19, wherein the receiving device is further configured to associate a first unused channel with the first distribution device and to associate a second unused channel with the second distribution device.
