is HDTV a worldwide standard?

Archived from groups: alt.tv.tech.hdtv (More info?)

Yes, but no. The HDTV formats (1080p/1080i/720p) are standardized by
the ATSC which is an International standards body. So this means HD
devices (not many of them to count) should work universally... I
suppose game consoles have proven this to be true between Japan, the UK
and the US (XBox and PS2 have select games that do support 1080i or
720p though component output)

For over the air reception (modulation), there are two standards COFDM
and 8VSB. The US is using 8VSB, most other parts of the world are using
COFDM so your set would not be compatible for over-the-air reception.

Mexico is also ATSC (8VSB)

The two countries that border the US and the country, S. Korea where the
IP royalties will go for 8-VSB. Strong endorsement for 8-VSB???

Hello,

ATSC from USA is meant for 60 Hz deflection systems, Europe has 50 Hz
deflection systems. There are many flatscreen displays that cannot
handle 50 Hz video (like from Euro1080 HDTV) even if it comes through a
DVI/HDMI interface. So a european standardisation body has adopted the
"HD-ready" logo for consumer equipment that is able to handle 50 Hz as
well as 60 Hz HD video...
