Japanese engineers at work on HDTV successor
29 May 2007 17:05
There is no doubting the crisp picture and cinema-quality audio of HDTV, but engineers in Japan are already beavering away at its potential eventual replacement, Super Hi-Vision (SHV).Scientists at NHK's Science and Technical Research Laboratories demonstrated their most recent SHV technology last week, PC World reports, and it was impressive, to say the least.
SHV pictures are made up of 4,320 horizontal picture lines and 7,680 vertical lines (32 megapixels) - the equivalent of 16 HDTV screens stacked up together.
Now NHK has created a new image sensor that can shoot an image that could be displayed using SHV's full capabilities. Until now, three separate cameras had to be used to produce the right resolution.
In a demonstration, NHK set up a camera three metres away from a scene with a newspaper in it. On screen, the stories printed on the pages of the newspaper could be read with the naked eye.
SHV is some way off, but the latest technology gives a tantalising glimpse of what consumers can expect in the future.
Other problems being worked on by NHK include compressing the SHV signal.
