At most trade shows, some companies go all out with their booth design, and I usually take some pics of the most beautiful ones. Here are a few I saw at NAB 2014.   In this display on the periphery of the Canon booth, some lenses were placed between a one-way mirror in front and a regular...

 Harmonic is not a company many consumers have heard of—it provides video-infrastructure services for the professional community. But its booth at NAB 2014 had several interesting demos related to UHD. Perhaps most important was a live UHD stream at 60 progressive frames per second. A playout...

 The Dolby 3D laser-projector demo in the Christie booth was accompanied by the company's Vive theater-audio system, which replaces the traditional horn-based speakers with line arrays using ribbon tweeters mounted directly in front of cone mid-range drivers. Vertical line arrays typically...

 Christie is one of the largest providers of DLP-based digital-cinema projectors, and it always has a big booth at NAB. This year, the company demonstrated a new laser-illuminated projection system designed to display Dolby 3D. Unlike RealD and Imax 3D, which use polarized light to isolate the...

 It seemed that nearly everyone at NAB was settled on using HEVC (High-Efficiency Video Coding), aka H.265, as the codec for UHD. It's often been said that HEVC offers 50 percent greater efficiency than the previous-generation H.264, aka AVC (Advanced Video Coding), resulting in files that are...

 Last week, the 2014 NAB (National Association of Broadcasters) convention was held in Las Vegas, and I was there to cover as much as I could for AVS Forum and TWiT, the online TV station that produces my Home Theater Geeks podcast. Be sure to check out my on-camera interviews at the show here...

 As it has for the last several years, NHK—Japan's public-broadcasting service—demonstrated 8K technology, what it calls Super Hi-Vision. With a pixel resolution of 7680x4320 (33 megapixels, four times the number of pixels in UHD), 8K seems like a distant dream—and completely unnecessary for...

 There was virtually no news about a UHD/4K physical-disc format at NAB, but Sony was touting its Pure Audio initiative to place entire albums of high-res music on current Blu-ray discs. Universal Music, Warner Music Group, and (of course) Sony Music have all signed on to produce such albums...

 Red Digital Cinema introduced its new Epic Dragon digital camera with 6K (6144x3160 or 19 megapixel) resolution. It's one of the highest-performance digital cameras available with 16 stops of dynamic range and frame rates up to 120 fps at 4K and 5K and over 80 fps at full-frame 6K. It records...

 Panasonic was showing a few interesting displays at NAB 2014. Perhaps the most interesting was a 98" UHD LED-LCD flat panel with full-array local dimming and 500 nits of peak-white output. The TH-98LQ70U will be available in September, but no pricing was announced. It will also be available in...

 There are several ways that UHD could be delivered to the home, including online, over the air, and physical disc. (I haven't heard much about cable or satellite delivery.) It seemed clear at NAB that the first method will be online or so-called IP (Internet Protocol) delivery. Sony had demos...

 One of the main reasons I went to NAB 2014 was to ascertain the state of UHD/4K standardization and the expected rollout timetable. Of course, the pixel resolution is well-established—3840x2160 for home-based systems—but what about other aspects such as higher dynamic range and bit depth...

 Just back from the 2014 NAB (National Association of Broadcasters) convention, industry consultants Michael Heiss, Chris Armbrust, and I talk about what we saw and heard there and how it could affect the content delivered to consumers, including the state of Ultra HD standardization, high...

 I roamed the show floor of the 2014 NAB (National Association of Broadcasters) convention to interview representatives of companies at the forefront of the content-creation industry. I was looking for the latest technologies that may affect what consumers will see and hear in the future...
