Ty, we always talk in terms of lines.

Thus 720 anything (for example, 720p) refers to a progressive 1280
pixel wide by 720 line high frame.

Similarly, 1080 anything (for example, 1080i or 1080p) refers to an
interlaced or progressive, respectively, 1920 pixel wide by 1080 line
high frame.

NTSC DV has a frame size of 720 pixels wide by 480 lines high
interlaced, which would be called 480i, not 720i. If it were
progressive instead of interlaced, it would be called 480p, not 720p.

Clear?
