The EVD "hype" has been here (in China, that is) for like, ages.
It is interesting that though the Chinese media has a lot of news about EVD's being better than DVD and being a national pride (as present international standards are mostly made by western countries and companies, China desperately needs its own standards to be more powerful in the intl market), there are seldom any mention about how exactly is EVD better than other formats, i.e. the technical specs. Moreover since EVD is less known outside China (and maybe inside China too - the computer magazines here talks about Vista and Blu-ray and HD but seldom EVD) compared to western Hi-Def formats, I am made curious: how is EVD, and can it do 1080p?
A quick search dug out a quite official-looking site for EVD: (Chinese only... apparently they have an English version, but the database is down. Note I'm not making any assurance that this is indeed the official site).
From several articles on the site we can see that the EVD standard uses DVD discs (format D5 and D9) as media - wow, I didn't know that, no wonder never have I heard the data capacity of EVD -, supports 720p and 1080i (not as much as the western Hi-Def formats), and utilizes MPEG2 and ExAC (custom audio coding standard) as compression algorithms. And there is, indeed, a copy protection scheme.
The site also metioned about a even lesser-known NVD and a Taiwan standard, FVD.
When I first heard that they've made a format called EVD, I thought that "it's just 'DVD++'". Today I know that E officially stands for Enhanced. But to me, it's just DVD++.

>>1 is not entirely stupid. 'Kay the article might be a bit boring... (The rants of a new user. Please note he is not a Japanese.)
Didn't know Slashdotters have already been introduced to FVD (which, by the way, looks like FUD - not that matters...).
