Abstract

Transmitting devices facilitate privacy protection of content broadcasted from the transmitting device to a receiving device without the need to modify the receiving device. A transmitting device may be adapted to acquire content, such as audio and/or video data, to be broadcasted by the transmitter for reception and use by a receiving device. A transmission range is selected to define a distance for broadcasting the content from the transmission device for reception and use by a receiving device. A frequency is also selected to be used for broadcasting the content. With the transmission range and frequency selected, the transmitting device may broadcast the content according to the selected transmission range and frequency.

Claims

1. An access terminal, comprising:

a transmitter module to broadcast content for use by a receiving device; and

a processing circuit coupled to the transmitter module, the processing circuit adapted to;

receive a transmission parameter;

select a transmission range in response to the received transmission parameter;

select a frequency on which to broadcast the content; and

broadcast the content according to the selected transmission range and the selected frequency.

2. The access terminal of claim 1, wherein the processing circuit is further adapted to acquire the content.

3. The access terminal of claim 2, wherein the processing circuit is adapted to acquire the content from a storage medium coupled to the processing circuit.

4. The access terminal of claim 2, further comprising a receiver module coupled to the processing circuit, wherein the processing circuit is adapted to:

receive the content from the communication network via the receiver module; and

store the content in a storage medium.

5. The access terminal of claim 2, further comprising a content capture module coupled to the processing circuit, wherein the processing circuit is further adapted to acquire the content via the content capture module.

6. The access terminal of claim 5, wherein the content capture module comprises at least one of a camera and/or a video camera and/or an audio recorder and/or an external storage device.

7. The access terminal of claim 1, wherein the received transmission parameter comprises a transmission power value.

8. The access terminal of claim 1, wherein the received transmission parameter is input by a user.

9. The access terminal of claim 8, wherein the user input transmission parameter comprises a distance value.

10. The access terminal of claim 8, wherein the user input transmission parameter comprises an index into an adjustment bar.

11. The access terminal of claim 8, wherein the user input transmission parameter comprises a transmission parameter selected based on a perceived quality of the content at a receiving device.

12. The access terminal of claim 1, wherein the processing circuit is adapted to select the frequency on which to broadcast the content from a frequency space that is one of unallocated or in white space.

13. The access terminal of claim 1, wherein the content includes at least one of audio and/or video data.

14. The access terminal of claim 13, wherein the broadcasted content comprises digital high-definition content for use by a high-definition receiving device.

15. The access terminal of claim I, wherein the processing circuit is adapted to select a transmission range that is sufficient to reach an intended receiving device and to prevent a receiving device located at a distance farther than the transmission range from using the broadcasted content.

16. A method operational at an access terminal for transmitting content for reception by a receiving device, comprising:

acquiring content to be broadcasted;

selecting a transmission range for broadcasting the content for reception and use by a receiving device;

selecting a frequency on which to broadcast the content; and

broadcasting the content from the access terminal according to the selected transmission range and the selected frequency.

17. The method of claim 16, wherein acquiring the content comprises receiving the content from a storage medium on the access terminal.

18. The method of claim 16, wherein acquiring the content includes generating the content with a processor on the access terminal.

19. The method of claim 16, wherein acquiring the content comprises:

receiving the content wirelessly from a communication network; and

storing the content in a storage medium.

20. The method of claim 16, wherein acquiring the content comprises acquiring at least one of audio and/or video data via a content capture module.

21. The method of claim 20, wherein acquiring the content via the content capture module comprises acquiring the content via at least one of a camera and/or a video camera and/or an audio recorder and/or an external storage device.

22. The method of claim 16, wherein selecting the transmission range includes selecting a transmission power for broadcasting the content.

23. The method of claim 16, wherein selecting the transmission range includes selecting the transmission range via a user input.

24. The method of claim 23, wherein selecting the transmission range via a user input includes inputting a distance value.

25. The method of claim 23, wherein selecting the transmission range via a user input includes adjusting an index into an adjustment bar.

26. The method of claim 23, further comprising selecting the transmission range via a user input based on a perceived quality of the content at a receiving device.

27. The method of claim 26, wherein selecting the transmission range via a user input based on the perceived quality of the content at a receiving device includes:

increasing the transmission range if the perceived quality is insufficient;

decreasing the transmission range if the perceived quality is sufficient; and

maintaining the transmission range when the transmission range is at a minimum value for providing a perceived quality that is sufficient.

28. The method of claim 16, wherein selecting the transmission range includes selecting a transmission range that is sufficient to reach an intended receiving device while preventing a receiving device located outside of the transmission range from receiving and using the broadcasted content.

29. The method of claim 16, wherein selecting the frequency on which to broadcast the content comprises selecting a frequency from a frequency space that is one of unallocated or in white space.

30. The method of claim 16, wherein broadcasting the content includes broadcasting digital high-definition content adapted for use by a high-definition receiving device.

31. An access terminal, comprising:

means for acquiring content to be broadcasted;

means for selecting a transmission range for broadcasting the content for reception and use by a receiving device;

means for selecting a frequency on which to broadcast the content; and

means for broadcasting the content from the access terminal according to the selected transmission range and the selected frequency.

32. The access terminal of claim 31, wherein the means for acquiring the content includes:

means for receiving the content wirelessly from a communication network; and

means for storing the content in an internal storage medium.

33. The access terminal of claim 31, wherein the means for selecting the frequency on which to broadcast the content comprises means for selecting a frequency from a frequency space that is one of unallocated or in white space.

34. A machine-readable medium comprising instructions for facilitating protected transmission of content from an access terminal for use by a receiving device, which when executed by a processor causes the processor to:

receive a transmission parameter;

select a transmission range in response to the received transmission parameter;

select a frequency on which to broadcast the content; and

broadcast the content according to the selected transmission range and the selected frequency.

35. The machine-readable medium of claim 34, further comprising instructions, which when executed by a processor causes the processor to acquire the content via at least one of a receiver module in communication with a communication network and/or a content capture module and/or a storage medium.

36. The machine-readable medium of claim 34, wherein the instructions, which when executed by a processor causes the processor to receive the transmission parameter includes instructions, which when executed by a processor causes the processor to receive a user input distance value.
