This article just made me more confused instead of explaining what the technology is and how it works. > would allow for more precise geolocating of television signals, ultra-high definition picture quality and more interactive programming, like new educational content for children and multiple angles of live sporting events What?? What does multiple camera angels have anything to do with the signal quality? What type of educational content is possible that's not possible with current TVs? Don't current TVs already support 4k? So what type of picture quality is it talking about? What type of interactive programming is it capable of that's not possible with current TVs? Someone please explain!
