John;
Thank you. I consciously declined to mention that "requirement" from my
post, to see if anybody sensible would recall the need to handle HDTV input
signals and output them in NTSC. I just can't wait to see those HDTV
signals in analog within a 6-MHz channel.
Now, a fool would handle MP@HL by using the most expensive technique to
down-rez HDTV to SDTV; someone who actually designed electronic circuits --
as opposed to people who try to read everything they can about 'electronic
design news' to inform them how to design circuits -- would choose the most
cost-effective technique consistent with the overall requirements. If the
most cost-effective technique produced bad pictures, they would crawl up the
quality tree until they found the sweet spot in the price/performance curve.
Can you imagine Grandma and Grandpa, who have never had cable, after turning
in their voucher and a few dollars (I don't the voucher can cover sales tax,
since that's a state matter), commenting while "Watching Dancing with the
Stars" that they're not sure if the decimation technique is better than
re-sampling to get 480i output, and maybe they should have bought a new
$2,000 HDTV set than hooking up the $4.00 stb to 'old Bessie."
I don't see it happening.

This STB of Bert's is meant to be "coupon compliant" so it by law cannot
have a true HD output. Since the highest resolution output it is allowed to
have is S-Video at 480i (component output at any resolution including 480p
is a disqualifying feature) then decimation is an acceptable downconversion
technique.
