Title: Visible Light Communication

Visible Light Communication

One day, you may be able to obtain customized information directly from your television's LED backlights, thanks to a new technology dubbed "Visible Light Communication." The LED lights transmit information by flickering at high frequencies; a device with a photodiode (for example, a cell phone) then picks up the transmitted signals.

According to Samsung, this new technology could have a profound impact on the future of TV, in part because it would allow advertisers to take a completely different approach to airing commercials.

Though Samsung says that products featuring Visible Light Communication won't arrive anytime soon, the technology has been demonstrated with working prototypes. The Nakagawa Laboratory of Tokyo's Keio University has done extensive research in Visible Light Communication, as well.

I was closing my Guardrail-like comment ("All you kids get off my lawn" and such).
