Abstract

A system and method of detecting and thwarting the use of unauthorized imaging systems at theatrical performances. Sensors are deployed at a theatrical event to detect a focusing signal and/or the RF signal of an unauthorized imaging device. De-focusing signals are used to disrupt the auto focus system of imaging devices that do not use IR focusing systems. A thwarting signal comprising invisible light frequencies may be combined to produce a thwarting signal that is received by the CCD of an imaging device as white light thereby rendering the recorded image unusable. Emission signatures of imaging devices are stored in a datastore and distributed to users of thwarting systems via a network. Emission signatures are associated with thwarting signals to allow detection and thwarting systems to respond quickly to the use of an unauthorized imaging device.

Claims

1. A thwarting system for preventing pirating of a theatrical experience comprising:

a network;

a processor connected to the network;

a content thwarting signal generator;

a sensor installed within a theatrical performance venue and connected to the network, wherein the sensor is adapted for;

detecting RF noise emissions within the theatrical performance venue; and

sending RF noise emission data to the processor; and

wherein the processor is adapted for;

receiving the RF noise emission data from the sensor;

determining if the RF noise emission data is indicative of a presence of an imaging device;

determining whether a content signal has been transmitted by the imaging device if the RF noise emission data are indicative of the presence of the imaging device; and

commanding the content thwarting signal generator to transmit a content thwarting signal to thwart the content signal if the content signal has been transmitted by the imaging device.

2. The system of claim 1, wherein the system further comprises a content signal datastore and the processor is further adapted for:

characterizing the content signal as a content signal signature;

associating the content signal signature with the content thwarting signal; and

storing the content signal signature and the associated content thwarting signal in the content signal datastore.

3. The system of claim 1, wherein the content signal is a spread spectrum signal, a Bluetooth signal, an 802.11(x) signal, an amplitude modulated signal, or an FM modulated signal.

4. The system of claim 1, wherein the content thwarting signal comprises a noise signal.

5. The system of claim 1, wherein the area wherein the theatrical performance venue is a room and the sensor is located on the interior walls defining the room.

6. The system of claim 1, wherein the theatrical performance venue is an outdoor theater and the sensor is mounted on structures arranged spatially so as to sense an area occupied by an audience.

7. The system of claim 1, wherein the processor comprises a location system configured for determining the location of the imaging device from which the emission emanates.

8. The system of claim 1, wherein the sensor is located in audience seating fixtures.

9. The system of claim 1, wherein the sensor comprises a sensor location identifier that is associated with a location within the theatrical performance venue.

10. The system of claim 1, wherein the system further comprises a location system, wherein the sensor comprises a transceiver, and wherein the transceiver comprises:

an antenna;

a local receiver; and

a local transmitter and wherein;

the local receiver is adapted for receiving the RF noise emissions from the imaging device;

the transmitter is adapted for sending an RF noise emission data to the location system in response to reception of RF noise emissions by the receiver; and

wherein the location system locates the imaging device based on the RF noise emission data.

11. The system of claim 1, wherein the sensor comprises a sensor location identifier that is associated with a location within the theatrical performance venue and the RF noise emission data comprises a sensor location identifier.

12. The system of claim 11, wherein the RF noise emission data further comprises a signal strength measure of the RF noise emissions received by the sensor.

13. A method of preventing pirating of a theatrical experience comprising:

receiving at a sensor RF noise emissions from a theatrical performance venue;

receiving at a processor RF noise emission data from the sensor;

determining at the processor whether the RF noise emission data are indicative of a presence of an imaging device;

determining whether a content signal has been transmitted by the imaging device if the emission data are indicative of the presence of the imaging device; and

commanding a content thwarting signal generator to transmit a content thwarting signal to thwart the content signal if the content signal has been transmitted by the imaging device.

14. The method of preventing the pirating of a theatrical experience of claim 13 further comprising:

characterizing the content signal as a content signal signature;

associating the content signal signature with the content thwarting signal; and

storing the content signal signature and the associated content thwarting signal in a content signal datastore.

15. The method of preventing the pirating of a theatrical experience of claim 13, wherein the content signal is a spread spectrum signal, a Bluetooth signal, an 802.11(x) signal, an amplitude modulated signal, or an FM modulated signal.

16. The method of preventing the pirating of a theatrical experience of claim 13, wherein the content thwarting signal comprises a noise signal.

17. The method of preventing the pirating of a theatrical experience of claim 13, wherein the theatrical performance venue is a room and the sensor is located on the interior walls defining the room.

18. The method of preventing the pirating of a theatrical experience of claim 13, wherein the theatrical performance venue is an outdoor theatre and the sensor is mounted on the structures arranged spatially so as to sense an area occupied by an audience.

19. The method of preventing the pirating of a theatrical experience of claim 13, wherein the sensor is located in audience seating fixtures.

20. The method of preventing the pirating of a theatrical experience of claim 13, wherein the RF noise emission data comprise a sensor location identifier that associates the sensor with a location within the theatrical performance venue.

21. The method of preventing the pirating of a theatrical experience of claim 20 further comprising using the RF noise emission data to locate the imaging device within the theatrical performance venue.

22. The method of preventing the pirating of a theatrical experience of claim 13, wherein the RF noise emission data comprise a signal strength measure of the RF noise emissions received by the sensor.

23. The method of preventing the pirating of a theatrical experience of claim 22 further comprising using the RF noise emission data to locate the imaging device within the theatrical performance venue.
