Standards

National Television Standards Committee - NTSC: This is named for the group that originally developed the black & white and subsequently color television system that is used in the United States, Japan, and many other countries. An NTSC picture is made up of 525 interlaced lines and is displayed at a rate of 29.97 frames per second.

Phase Alternate Line - PALThis is the video format standard used in many European countries. A PAL picture is made up of 625 interlaced lines and is displayed at a rate of 25 frames per second.

Sequential Color and Memory - SECAMThis video format is used in many Eastern countries such as the USSR, China, Pakistan, France, and a few others. Like PAL, a SECAM picture is also made up of 625 interlaced lines and is displayed at a rate of 25 frames per second. However, the way SECAM processes the color information, it is not compatible with the PAL video format standard.
