bleeding edge of technology in the current consumer market, a new technology from Japan makes the latest HD movies specifications look simply archaic. Last week, At 7680x4320, over 33 million pixels make up the image – this represents 16 times the resolution of a 1080p image. To get a picture of the bump in resolution, a Super Hi-Vision image could be approximated by tiling 16 of today’s best HDTVs together.
In comparison, a 1080p picture represents a six-fold jump in resolution over standard-definition television.
Unlike current HD cameras, which are hitting the hands of consumers, the Super Hi-Vision camera sensors are not yet able to capture a full color picture. The latest prototype Super Hi-Vision sensor is monochrome, but to capture color images.
The prototype is super-fast too, able to capture data at a rate of 4,000 frames per second.
improved image. While today’s best home theaters have 7.
1 setups, the audio component paired with Super Hi-Vision is 22.2.
However, it may be quite some time before such an image is delivered on media, let alone broadcasted, as an uncompressed signal requires a bit-rate of 24Gbps.
A single minute of Super Hi-Vision footage would require 194 GB of storage.
To help ease that burden, NHK is enlisting the help of ATEME, a provider of MPEG-4 and H.264 solutions, to compress the 7680 x 4320 "Ultra HD" video – creating a new video standard.
ATEME says that it is currently next-generation standard using existing MPEG-4 AVC compression technology.
Ultra HD," said Benoit Fouchard, Vice President of Sales, Broadcast and Broadband for ATEME. "ATEME's MPEG-4 AVC encoding has always been accepted as the world's best, and NHK's sole reliance on our technology proves we are for HD.
We are very proud to be working with them and look forward to a Super Hi-Vision cameras, recorders, encoders and projectors planned for 2009. NHK estimates that satellite transmission tests will begin in 2011, and by 2020, Ultra HD will be ready for broadcast to households.
