The patent reads:
“A transmitter can be located in areas where capturing pictures and videos is prohibited (e.g., a concert or a classified facility) and the transmitters can generate infrared signals with encoded data that includes commands temporarily disabling recording functions.”
It doesn't make this 'feature' any better.
