NHK and Mitsubishi develop the first H.265 encoder for 8K video
NHK's 8K Super Hi-Vision is an extremely bandwidth-heavy format -- so much so that earlier tests used gigabit-class internet links rather than traditional TV broadcasting methods. Thankfully, both the broadcaster and Mitsubishi have developed an encoder that could keep data rates down to Earth. The unassuming metal box (above) is the first to squeeze 8K video into the extra-dense H.265 (HEVC) format, cutting the bandwidth usage in half versus H.264. Its parallel processing is quick enough to encode video in real time, too, which should please NHK and other networks producing live TV. We'll still need faster-than-usual connections (and gigantic TVs) to make 8K an everyday reality, but that goal should now be more realistic.

JVC will launch its first (sort of) 8K projector later this month in Japan, for $261,000
JVC showed off a prototype 8K Super Hi-Vision projector in 2008 at CEATEC, and now it's ready to ship a real product later this month, dubbed the DLA-VS4800. JVC's e-Shift pixel technology is at play here, which we first saw in consumer products with the '4K' projectors it shipped in 2011, and updated in last year's models. Basically the D-ILA display panel inside the device is half the resolution (in this one, 4,096 x 2,400) but projects two images alternated at 120Hz, one shifted slightly diagonally. This creates the impression of a higher res display, without actually upping the pixel count.
Based on our demos of the tech at CEDIA for the last two years, the effect is very convincing, however with AV Watch's presumed price tag of 25 million yen ($261k US -- and that's without the 4 available lenses, which have no price), we might want a few more real pixels, if such a product were available for purchase. Still, if you want the first 8K display device on the block, this is your only choice, unless you can convince Sharp to part with one of its sweet 8K Super Hi-Vision LCD prototypes (we've asked, we've begged, we've planned Ocean's 11-style heists -- it's not possible.) The other issue is that you'll still need some content to view, and with the roadmap currently putting test broadcasts in 2016, leaving this one to the museums and planetariums it's intended for may be the best course of action.

NHK demonstrates 8K 3D digital binoculars: 16x ‘lossless’ zoom at 1080p (hands-on)
Alongside its Super Hi-Vision TV demonstrations, Japan's national broadcaster had some 3D goggles also taking advantage of that 8K resolution. With 16 times the pixels of typical 1080p content, these prototype binoculars provide the same multiple of zoom from an 8K feed -- that is 16x zoom without losing any of original data. We got to grips with a the master model here at CEATEC, and were able to pan up and down, as well as manipulate a lever to close in on views of both Mount Fuji and Tokyo's very recent Skytree tower. NHK mentions that it could see the devices being used to show off other sightseeing spots in the future, but we don't expect home installations any time soon.
