Prepare To Upgrade Your TVs AgainWe assumed the gorgeous 8K ultra-HDTVs we saw at CES this year were years away. But Japan's NHK has just completed the first over-the-air broadcast of a 7680x4320 signal using UHF frequencies—just when you'd finished paying off your giant HDTV display.The compressed Super Hi-Vision signal, as the NHK calls it, was broadcast over a distance of about 2.7 miles without any errors on the receiving end. So it's not like the broadcaster has started blanketing Tokyo in a glorious 8K signal just yet, but it's an important milestone. And to facilitate all that data, 16 times the resolution of a 1920x1080 HD image, the researchers spread the signal across a couple of UHF frequencies. Which means that one day the government might have to rustle up even more spectrum space if 8K ends up replacing our recently-deployed hi-def networks. [NHK via AV Watch via Engadget HD]high-definition camera developed a compact camera head for Super Hi-Vision□ NHK, as the next generation of television broadcasting services immersive, but the research and development (SHV) Super Hi-Vision.- developed a compact camera head for single-plate color imaging method SHV of a prototype 33 million pixel image pickup device this time, newly equipped with a color filter, color images can be captured by one image pickup device. In the single-plate color imaging system is unnecessary because the prism, we were able to achieve significant reduction in size and weight of the camera head for SHV.□ weight of the camera head is about 4kg, weight reduction has been less than 1/5 compared to the camera head for SHV've been using so far. In addition, by having a miniaturized camera head, as it is now possible to use a variety of lenses for SLR cameras.□ The newly developed camera head can be found at the NHK Science & Technical Research Laboratories of the general public will be held on Sunday 27 to Thursday 24 May.
