Subject: the mess of digital tv standards is getting worse

This is what happens when you refuse to compromise early in the standards
game and choose a uniform system for the future. Not only do we have 18
hdtv standards, but another half dozen to convert them for PCs, & vice
versa to TVs. What a mess!

And what the industry refuses to acknowledge is that each conversion
DEGRADES the image further. It is physiological impossible to de-interlace
interlaced images without reducing the resolution. All this could have been
solved if hdtv/dtv never had interlace at all and adopted square pixels.

See also today's Wall Street Journal for more nonsense on a new web tv chip
by Broadcom-- their decoder box for a tv set costs as much as a full
low-end PC with a monitor.
