Guest_Jim_* Posted May 20, 2015 Posted May 20, 2015 Some believe that the future for some technologies will involve more directly linking them, and we already see something like this with television content that our phones can listen and react to. The trick for such a future is keeping this communication hidden from the viewer, or at least unobtrusive. Researchers at Dartmouth College have achieved just that, while still encoding information directly into the video displayed on screen. Some attempts to encode data into video have been made before, but one does not necessarily want a QR code to appear on top of whatever they are watching. The Darthmouth researchers' solution, called HiLight, is to use the alpha channel of the image, so the information can be found in pixel translucency changes. This way the communication and screen content is separated, hiding it from the users, yet still allowing for real-time communication. Also, because it uses the visible part of the spectrum, there is not electromagnetic interference.
