The picture Horizontal resolution has to be at least 720 lines
(ex. 1024x720 or 1280x720).
For comparison, standard def. has only 480 lines (ex. 720x480 in NTSC)

The current standard calls for a minimum resolution of 1920 by 1080 pixels (pixels are the tiny dots that make up a video or computer image). This standard delivers more than five times the resolution, color, depth of field and detail of standard video. In order for a program to be truly hi-def, both the camera that records it and the screen on which it is displayed must be able to generate that minimum number of pixels. The hi-def standard calls for a widescreen, or 16:9 format.
