Passive 3D seems to be the new home entertainment hotness at CES this year, but that doesn't mean the industry has given up on active shutter. Case in point, Freescale Semiconductor and RealD have announced they're developing an "enhanced 3D active eyewear solution" that combines Freescale's RF4CE platform for the over-the-air 3D synchronization with RealD's switching, filtering, and optical technology. Powered by Freescale's MC1323x System on a Chip, the new system hopes to eliminate many the problems plaguing IR-based active shutter like line-of-sight and of field-of-vision limitations. It should also allow 3D glasses to operate from longer distances, and since it takes advantage of the same radio frequency used by remotes, it could lower overall costs for manufacturers to boot. Keep in mind though that unlike NVIDIA's RF-based 3D Vision Pro Tech, all of these wondrous promises are just talk with no walk -- so we'll throttle our excitement until we can go eyes-on with some actual gear. For all the details hit up the PR after the break.
