NHK makes first successful Super Hi-Vision OTA broadcast, man cave owners giggle with glee
Fresh off from successfully shrinking its Super Hi-Vision camera, Japan's NHK is sticking another feather in its cap -- the first over-the-air broadcast of its super-duper high-resolution technology. The broadcaster says it recently managed to send a compressed Super Hi-Vision signal from the roof of its Science and Technology Research Laboratories in Tokyo to a distance about 4.2 kilometers away with no issues. NHK used two UHF channels during the experiment. To optimize and boost transmission capacity, NHK leveraged technologies such as orthogonal frequency-division multiplexing (OFDM) and multiple-input multiple-output (MIMO). Low-density parity check coding was also used for error correction. NHK has been constantly experimenting with its Super Hi-Vision high-resolution (7,680 x 4,320) video format, including a UK-to-Japan broadcast via a 24Gb/s internet connection in 2010. Folks who happen to be in Japan from May 24th to 27th can check the tech at the NHK labs' open house in Tokyo's Setagaya ward.
MPEG group working on AVC replacement for Ultra High Definition video of the future
The tech around Super Hi-Vision technology may not be completely worked out yet, but with that on the way, plus HD for mobile devices and even more streaming, the 88th meeting of the MPEG/ISO standards group in Maui was apparently a busy one as attendees voted to work on a new, better form of compression to replace MPEG-4 AVC. "High Performance Video Coding" (HVC) is just a dream at the moment, but be sure to pencil that in as one more spec to look out for in the future. Of course, they didn't mention a delivery system for 22.2 channel audio, but we'll just assume that's being handled as well.[Via EE Times UK]
Super Hi-Vision creeps towards reality with latest breakthrough
Because 1080p and even Quad HD just aren't high-def enough, Japanese broadcaster NHK has announced new breakthoughs in it's Super Hi-Vision (formerly Ultra High Definition Video) technology. They've been showing it off periodically for the last several years, but the latest step towards living rooms is a single image sensor that for TV cameras that is capable of full SHV (7,680 x 4,320) resolution. Previous prototypes were limited to half that resolution, but now they're focusing on shrinking the equipment necessary to encode/decode the uncompressed 24Gbps SHV stream to 124Mbps from its current to fit in broadcaster headends and UHDTVs near you. While those pixels are nothing to sneeze at, we're still trying to figure out where to get speakers for the planned 22.2 channel audio.
NHK makes a showing at NAB and brings Ultra HD
Hey! High definition is confusing enough. People are just now getting used to 720p/1080i and 1080p, so here comes NHK again with their UHDV. Ultra High Definition TV has a resolution of a measly 7,680 x 4,320 which works out to be 16 times the current 1920 x 1080 standard we have today. This is nothing new though guys. (and gals) They have been showing this off around the world for a couple of years now starting at NAB back in 2004. It is still pretty cool though and when you combine that uber-high resolution with 22.2 channels of audio...WOW. Simply wow. Don't except Circuit City or Best Buy to carry this anytime within the decade though. Or even within the next decade, as they are aiming for a 2025 launch. So if you save a dollar a day till the launch in 19 years, you will have just under $7000 to be the first kid on the block with UHDV![thanks to everyone that sent this in]
