Chief Twit Leo Laporte and I explore the show floor at CES 2012. Our first stop is the DTS booth to interview legendary producer/engineer/musician Alan Parsons and engineer/producer Elliot Scheiner. Next, we head to the LG booth, where Leo is impressed with the 3D video wall and we take a look at the 55-inch OLED flat panel and Google TV. At the Sharp booth, Kerry Hodel explains the company's ICC-4K upscaling and shows us a stunning 8K display, after which we wander over to Samsung, where Stuart Silloway shows us the ES8000 LED-LCD TV, Samsung's 55-inch OLED, and the Verizon FiOS app. Finally, we take a quick look at Sony's Crystal LED flat panel, which seems to be that company's version of OLED.
