In this special episode live from the 2012 National Association of Broadcasters (NAB) convention in Las Vegas, Leo Laporte and I walk the show floor, talking to representatives from Canon, Panasonic, JVC, and Sony about new technologies that will improve the consumer experience of TV and movies. Particularly interesting is the rapidly falling cost of 4K digital-video cameras from Canon, JVC, and Sony as well as a new 3D conversion technology from JVC. We also talk to Panasonic's Peter Fannon about the upcoming Summer Olympics in 3D and see 4K flat-panel reference monitors in the Canon, JVC, and Sony booths that look amazing even at relatively small sizes.
