HDTV可以达到逐行扫描800线或隔行扫描1080。NTSC TV一般是525线, 其中可用的为480线, 所以又叫480i(interlace), PAL制TV是625线。

谁说HDTV没成型的,我的好多朋友和同事都在用HDTV, rogers和bell都有数字HDTV节目,看dvd也只有HDTV才能表现出来。

No. There is no major improvement if you watch analog TV program with a HDTV.

hdtv is a standard, not equipment. hdtv standard has 720p, 480p, 1080i. in terms of resolution, it varies from each individual tv.

No, you are wrong. For current HDTV sets, they should support all these resolutions you mention.

yes, they sure support all above standards. but they still have different resolutions.e.g. Panasonic. TH-37PWD4UY 37" - 853 X 480, TH-42PWD5UY 42" - 853 X 480, TH-42PHD5UY 42" - 1024 x 768, TH-50PHD5UY - 50" 1366 X 768.
