HDTV=High Definition TV

Resolutions

Name	Resolution	Scanning	Aspect Ratio
480i	640 x 480	Interlaced	4:3 (1.33)
480p	640 x 480	Progressive	4:3 (1.33)
720i	1280 x 720	Interlaced	16:9 (1.78)
720p	1280 x 720	Progressive	16:9 (1.78)
1080i	1920 x 1080	Interlaced	16:9 (1.78)
1080p	1920 x 1080	Progressive	16:9 (1.78)

The most common broadcasted HDTV resolutions are 720p (mostly for sports) and 1080i. 1080p would be nicer, but requires too much bandwidth currently. Most HDTV consumer products are less than 1080i/p, for instance projectors are most often 720p.

LCD/Plasma TVs are quite often 1366x768 which is a widescreen resolution of the PC resolution 1024x768 and kinda maps to 720p.
