The 720x480 DVD resolution is associated with which video standard?

Explanation:
720x480 is the standard-definition resolution tied to the NTSC video system. In NTSC regions, video uses about 29.97 frames per second and 480 visible lines per frame, so DVDs encoded for those regions adopt 720x480 as the pixel grid (with the final display aspect adjusted by pixel aspect ratio to show 4:3 or 16:9). PAL and SECAM, by contrast, use 720x576 and 25 fps, and there isn’t a real NTSC-PAL hybrid. So the 720x480 DVD resolution aligns with NTSC.
