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
