[opendtv] Re: HP and Philips to Begin Licensing Video Content Protection System to Manufacturers after Gaining FCC Approval

Trouble is that hardly anyone has considered broadcasting true SD. Current DVDs 
are better than most broadcast television because it is fully component video 
sampled to ITU R601. Most of the stuff touted as "SD" quality is merely NTSC 
quality.

To define the quality difference, consider this:

NTSC

Luma bandwidth: to 3 MHz (if your lucky).
Chroma bandwidth: 500kHz

SD

Luma bandwidth: to 5.5 MHz
Chroma bandwidth: to 2.75 MHz

Also consider the NTSC artifact garbage and the loss of diagonal luma 
resolution through comb filter decoders, much of the so called "SD" you sees 
today is really awful.

Maybe we can learn from our European counterparts who abandoned composite PAL 
in the studio years ago.

Cheers,

Terry Harvey
