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 limita
