MPEG group working on AVC replacement for Ultra High Definition video of the future

by Richard Lawler posted May 5th 2009 at 9:56PM


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.

Super Hi-Vision creeps towards reality with latest breakthrough

by Richard Lawler posted Jun 1st 2007 at 7:53PM

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!
