What is ATSC and NTSC?

What are the two types of television systems?
From the early experiments with visual transmissions, two types of television systems came into existence: mechanical television and electronic television. Mechanical television developed out of Nipkow’s disk system and was pioneered by British inventor John Logie Baird.
Is analog or digital TV better?
