What On Earth Possessed Me?

… to decide to blog about questions? I began by making everything a question. <--That felt good. Now, here’s the question that I am currently exercised upon: Is DVD-Video a worldwide standard? Does it work with NTSC, PAL, and SECAM?

Answer: The MPEG video on a DVD is stored in digital format, but it’s formatted for one of two mutually incompatible television systems: 525/60 (NTSC) or 625/50 (PAL/SECAM). Therefore, there are two kinds of DVDs: “NTSC DVDs” and “PAL DVDs.” Some players only play NTSC discs, others play PAL and NTSC discs. Discs are also coded for different regions of the world (see 1.10). NTSC is the TV format used in Canada, Japan, Mexico, Philippines, Taiwan, United States, and other countries. PAL is the TV format used in most of Europe, most of Africa, China, India, Australia, New Zealand, Israel, North Korea, and other countries.
