The Japanese government will be starting a joint project with some Japanese companies to develop a successor to HDTV.
The plan is to make "Super Hi-Vision" be available in 2015 - and it will also be promoted as a new international standard. The new standard brings a breathtaking 33 million pixels - more than sixteen times the resolution of 1080p.
Obviously these displays would also work extremely well as computer displays - once graphics cards are built that can drive them... quad dual-link DVI's anyone?
Let's see...
33Mpix * 3 bytes per pixel = 100MB/frame
60hz * 100MB/frame = 6,000MB/sec
GULP.
That's 6GB/sec for uncompressed video at 60HZ!
Hmm... we need fatter pipes. Even with MPEG4 we'd likely need 50-100Mbps for excellent quality.
