The two popular video standards used around the world are National Television System Committee (NTSC) and Phase Alternating Line (PAL). NTSC is used in most of the Americas and in Japan, South Korea, Taiwan, Philippines and Myanmar. PAL is used mostly in Europe, Asia and Australia.
Phase Alternating Line (PAL) is a colour encoding system for analog television. It was one of three major analogue colour television standards, the others being NTSC and SECAM. In most countries it was broadcast at 625 lines, 50 fields (25 frames) per second, and associated with CCIR analogue broadcast television systems B, D, G, H, I or K.
The major distinction between NTSC, PAL, and Secam is that NTSC is an abbreviation for National Television Standard Committee, PAL is an abbreviation for Phase Alternating Line, and Secam is an abbreviation for Sequential Couleurmmoire.
The primary visual difference between NTSC and PAL systems for high definition TVs (HDTVs) is in the refresh rate. NTSC refreshes the screen 30 times a second, while PAL systems do so 25 times a second.
Television standards conversion is the process of changing a television transmission or recording from one video system to another. Converting video between different numbers of lines, frame rates, and color models in video pictures is a complex technical problem.
