Abstract

Often, during an event, such as a movie, play, concert, opera, etc., viewers of the event attempt to illicitly record the event. Such illicit recording attempts may be interfered with by using emitters that emit radiation that interferes with recording and/or operation of the recording devices. For example, infrared emitters may be used to saturate an event viewing area. The infrared, while non-visible to human viewers, is received and recorded by recorders using charge-coupled devices (CCDs), such as conventional digital cameras, movie cameras, television cameras, telescopes, etc. Other radiation can be emitted based on the type of recorder with which one desires to interfere. Alternatively, or in addition thereto, emitters may also be used to send commands to recorders, such as stop, rewind, eject, etc., to interfere with operation of the recorders.

Claims

1. A method for interfering with illicit attempts to record an event, comprising:

identifying a starting point for projecting interference during an event; and

emitting a radiation that is not human perceptible during the event that will interfere with recording devices used during the event, wherein the radiation comprises infrared.

2. The method of claim 1, wherein the emitting the radiation occurs according to a selected one of the following intervals:

randomly during the event, continuously during the event, at selected moments of interest during the event.

3. The method of claim 1, further comprising:

emitting the radiation according to a pattern.

4. The method of claim 3,

wherein the pattern comprises selected ones of:

a watermark, purchase instructions for obtaining a legitimate copy of the event, a message.

5. The method of claim 3, wherein the pattern comprises a text message.

6. The method of claim 3, further comprising:

projecting the event against a viewing surface that will reflect the radiation; and

emitting the radiation towards the viewing surface so that illicit attempts to record the event result in a recording of the radiation as well.

9. The method of claim 1, wherein determining the interference starting point comprises detecting the start of the event.

10. The method of claim 9, wherein detecting the start of the event comprises detecting a starting signal issued during the event for triggering starting interference.

11. The method of claim 10, wherein the event is provided as a recording, and wherein the signal is embedded within the recording.

12. The method of claim 9, wherein detecting the start of the event is based at least in part on detecting a change in human-perceptible characteristics of the event.

13. The method of claim 12, wherein the changed human-perceptible characteristic comprises at least one of:

a change in lighting for the event, a change in sound for the event, and a change in texture.

7. A method for interfering with illicit attempts to record an event, comprising:

identifying a starting point for projecting interference during an event; and

emitting a radiation that is not human perceptible during the event that will interfere with recording devices used during the event;

wherein the emitting the radiation comprises emitting control instructions to affect operation of recording devices used during the event.

8. The method of claim 7, wherein the control instructions comprise selected ones of the following operation commands:

stop, rewind, fast forward, power off, power on, erase recording media, identify the recording device, and sound theft alarm.

14. An article, comprising:

a machine-accessible media having associated data for interfering with illicit attempts to record an event, wherein the data, when accessed, results in a machine performing;

identifying a starting point for projecting interference during an event; and

emitting a radiation that is not human perceptible during the event that will interfere with recording devices used during the event, wherein the radiation comprises infrared.

15. The article of claim 14 wherein the machine-accessible media further includes data, when accessed by the machine, results in the machine performing:

emitting the radiation according to a pattern.

16. The article of claim 15 wherein the machine-accessible media further includes data, when accessed by the machine, results in the machine performing:

projecting the event against a viewing surface that will reflect the radiation; and

emitting the radiation towards the viewing surface so that illicit attempts to record the event result in a recording of the radiation as well.

18. The article of claim 14 wherein the data corresponding to determining the interference starting point includes further data, when accessed by the machine, results in the machine performing:

detecting the start of the event.

19. The article of claim 18 wherein the data corresponding to detecting the start of the event includes further data, when accessed by the machine, results in the machine performing:

detecting a starting signal issued during the event for triggering starting interference.

20. The article of claim 19, wherein detecting the start of the event is based at least in part on detecting a change in human-perceptible characteristics of the event.

17. An article comprising a machine-accessible media having associated data for interfering with illicit attempts to record an event, wherein the data, when accessed, results in a machine performing:

identifying a starting point for projecting interference during an event;

emitting a radiation that is not human perceptible during the event that will interfere with recording devices used during the event; and

emitting control instructions to affect operation of recording devices used during the event.

21. A system comprising:

a focus area in which an event may be presented; and

one or more emitters disposed about the focus area configured to emit a human imperceptible emission perceptible to a recording device used to record the event, wherein the human imperceptible emission comprises infrared.

22. The system of claim 21, wherein the human imperceptible emission comprises selected ones of:

control instructions which when received by the recording device result in a change of state for the recording device, and a message which becomes human perceptible in a recording of the human imperceptible emission.

23. The system of claim 21, wherein the focus area is a selected one of:

a stage, a screen, and a projection surface.

24. The system of claim 21, wherein a first one of the emitters is configured to emit at least a portion of the human imperceptible emission towards the focus area.

26. The system of claim 21, wherein at least one of the emitters is configured to emit a message which becomes human perceptible in a recording of the human imperceptible emission, wherein the message comprises selected ones of an advertisement, a theft warning, a watermark, and a legal notice.

27. The system of claim 21, further comprising:

an event monitor operable to identify points of interest within the event;

an emission control communicatively coupled with the event monitor and operable to activate at least one emitter when a point of interest is identified.

25. A system comprising:

a focus area in which an event may be presented; and

one or more emitters disposed about the focus area configured to emit a human imperceptible emission perceptible to a recording device used to record the event;

wherein a first one of the emitters is configured to emit at least a portion of the human imperceptible emission towards the focus area, and

wherein a second one of the emitters is configured to emit at least a portion of the human imperceptible emission away from the focus area.
