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.
