When I listened to the very first CDs in the early 1980s, I realized one thing immediately:

When you give up one kind of distortion, it gets replaced with another.

If I get NTSC reception, but it's of poor quality, how do I categorize "perfect" ATSC reception? Is it "exactly reproducing", "replicating", or something else?

How about if my ATSC reception drops out during touchdowns and resumes in time for commercials? How do I compare that to constantly snowy or ghosty NTSC? Is there a scale of irritation I can use? ;)

Notice that “exactly reproduce” is a much narrower term than “replicate.” You might want to look up replicate in a real dictionary.

Also, nobody on this list has any legal authority, and Mark Aitken and I are the only who comment on this list and participate in ATSC committees – and I am only involved in the T3/S1 specialist group on metadata.

What people say on this list has no weight. And, in the case of a few people, what is said is 180 or so degrees from anything real.

That said, 8-VSB will replicate NTSC, if broadcasters use the maximum power permitted by them. But, it won’t “exactly reproduce” NTSC in the near field for some time to come. In the far field, it will exceed NTSC in coverage.
