J.S., You mean that CUBE still may appear on some radar screens as a faint blip,as when Tinkerbell gives off that weak signal of flickering light in Peter Pan.
On the usenet, when they argue over digital video they make reference to CUBE....

An excerpt....
So lets look at the relative resolutions of 480i, 480p, 720p, 1080i.
We'll consider luminence resolution only
Video Freq. Pixels painted
Format Response in 30th of a second
-------------------------------------------------------------------
NTSC 5 Mhz 240,000
480i component ~10 Mhz 240,000
720x525p (DVD) 22.6 Mhz 756,000
1280x750p 57.6 Mhz 1,829,000
1960x1125i 64.8 Mhz 2,205,000
Note that 480i component video takes a higher frequency response due to
the higher chroma detail.
So from this we see that the two best forms of HDTV are about an order of
magnitute higher resolution than NTSC (that's 1000% not 15,000%). DVD
through a progressive scan player offers a factor of 3 improvement over
NTSC in pixels, and it is a factor of 2.5-3 worse than the higher
resolution modes of DTV. So it falls nicely in the middle...... |
