Japan's NHK broadcasters demo Super Hi-Vision system
Researchers at Japan's public broadcaster, NHK, have unveiled their Super Hi-Vision system, boasting a staggering 7,680x4,320 resolution.
It's equivalent to a 4x4 grid of 1080p high definition TVs, and an uncompressed video stream would require 24Gbps of bandwidth. Even with MPEG-4 AVC/H.264 compression, it still takes up 128Mbps, which is around six times the size of current high definition broadcasts.
It's just a prototype at present, so we shouldn't be too concerned that our new 1080p HDTV sets are obsolete. We're not even getting 1080p broadcasts here yet, and certainly don't have the capacity to stream such a humongous amount of data.
If and when it comes out of prototype, wealthy Japanese consumers will likely get it first, leaving us drooling over 4,320p resolution.
I thought that the organisation had the ability to produce a prototype of twenty times 1080p for large screen displays.
Since, the diagonal screen size hasn't been given they may still have the ability to upscale the six times to twenty times.
Does any person knows not only what diagonal size the six times relate to, but the maximum diagonal size they could scale it up to?
