[Note:  This item comes from reader Mike Cheponis.  There is a good  
message here.  Look how long its taken us to move from NTSC to HDTV  
video, and we're still not there yet.  How long will it take us to  
move from HDTV to something like this?  DLH]

TOKYO — Aiming at next-generation broadcasting, Japan Broadcast  
Corporation (NHK) has demonstrated a live relay of a 4x x 8k  
resolution Super Hi-Vision program connecting a 260-km distance by a  
fiberoptic network.

NHK's next-generation broadcasting system can convey the sensation of  
reality to viewers. Super Hi-Vision is the provisional format for  
that purpose, achieving 7680 x 4320 pixels.
It already demonstrated the images of Super Hi-Vision at the 2005  
World Exposition, Aichi, Japan, held from March to September in Aichi  
this year using a preliminary prepared video footage.
NHK developed a Super Hi-Vision camera equipped with 8 megapixel CCD  
image sensors that can take 4k x 8k images. In the field test, it  
sent the two cameras to a sea park and sent baseband signals without  
image compression using an fiberoptic network formed by multiple  
network companies.
The signal of the total 24 gigabits per second was divided into 161.5  
Gbps HD-SDI signals to sent using the DWDM (dense wavelength division  
multiplex) method.
"Super Hi-Vision has huge information and was difficult to transmit.  
Using 16 waves on optic fiber, we succeeded a live relay over a long  
distance. This means that Super Hi-Vision proved the possibility of  
being a future TV broadcasting technology," said Mikio Maeda, senior  
research engineer of the laboratory.
