In Pictures: NHK's Successor to HDTV

This prototype camera, fitted with NHK's new Super Hi-Vision image sensor, can capture a live monochrome video image at 7680 by 4320 resolution.

Until now NHK used this experimental Super Hi-Vision camera, which contains four image sensors with half-SHV resolution. A new image sensor just developed should change this.

This prototype Super Hi-Vision encoder can encode a 24-gbps video signal to a 128-mbps MPEG4 AVC stream in real time using 16 encoders in parallel.

Visitors to NHK's Science and Technical Research Laboratories in Tokyo check out a demonstration of Super Hi-Vision television, a next-generation high-definition TV system.
