Here is a decent history of Taiwan and 8-VSB. I noticed that the ATSC
kept Taiwan on their site as an ATSC country long after Taiwan had
officially switched. They may still list them as ATSC. What does that
mean? I doubt if Taiwan is paying its ATSC dues.

"In 1998, a formal decision was made for Taiwan to adopt the US
‘advanced television systems committee’ (ATSC) digital standard. Based
on 8-vestigial side-band (8-VSB) technology, ATSC appeared at the time
to be a logical choice, given its ready application to 6-MHz channels
and the NTSC standard being used for analogue TV."
And....
"After changing the pilot station equipment from 8-VSB to DVB-T devices,
it was found that the problem of multi-path interference was largely
solved,” says Chung. By the end of June 2001, Taiwan had reversed its
original decision and adopted the DVB-T standard."
