A newly-granted Apple patent could have big implications for concert-goers keen to record live acts on their phones.
Filed by Apple in 2011 and granted this week, the document - snappily-titled "Systems and methods for receiving infrared data with a camera designed to detect images based on visible light" - sets out a system for remotely disabling iPhone cameras, using a live concert as a prime example of where it could work.
It uses as infrafred beam placed on stage to block any iPhone pointed towards the performers. Users would merely get a "recording disabled" message.

Fans recording live performances on smartphones is becoming a nuisance for both concert-goers and performers alike, reports The Guardian.

The site also adds that the infrared aspect is now slightly outdated and that more modern forms of transmission, such as iBeacons, would make more sense.
