At the New Scientist :
quote:The technique of hiding control signals in sound has been developed by Scientific Generics, based at Harston near Cambridge, UK. "We can use the existing infrastructure, putting data in TV sound, over a public address system or a music CD, or in an e-mail or an MP3 file," says Ian Hosking. The company is patenting the technique, which it calls "intrasonics".
The idea of controlling devices with sound is not new. Some early television remote controls emitted ultrasonic bleeps. But they were unreliable. Traffic noise could switch off the television and the ultrasound often upset household pets.
In the new system, coded control signals are spread over a wide range of frequencies, but they are too faint to be audible on a normal domestic sound system. The technique is adapted from spread spectrum technology, which the military developed for more secure radio communications.
I thought they already held instructions for us anyway. Guess it's another upgrade to mind control. We are watching FOX.
