Video Broadcast Formats: NTSC and PAL
Have you ever bought a VHS or DVD only to have it not play correctly in your player? If so, you may be trying to play a video that is captured in a different format than your tape player. Two formats, NTSC and PAL, used alternately worldwide, are the most common forms of encoding systems for broadcast television.

NTSC stands for the National Television System Committee and is the standard format of broadcast for North America and most South American Countries. Developed originally in 1941, the first strand of NTSC format was not compatible for color broadcast. It was not until 1953 that the second, modified version of NTSC was released, allowing for television broadcast in color.

Phase Altering Line, or PAL, is the encoding format used in European countries, Brazil, Argentina, China, India, Australia, and most African countries. This analog television encoding system was unveiled in 1963 by Walter Bruch at Telefunken, a German radio and television company. It was not until 1967 that PAL began broadcast in color. The PAL format was created to combat with transmission issues created during broadcast with the NTSC format.

The major difference between NTSC and PAL broadcast formats is the line count and frame rate. NTSC broadcast has 525 individual scan lines captured at 30 frames per second (525-line/60Hz); allowing for tint control that is adjusted manually by the user. PAL has 625 individual scan lines captured at 25 frames per second (625-line/50Hz). The PAL format uses phase reversal to automatically cancel any hue errors, making a manual adjustment to the tint or color unnecessary.

On June 17, 2009 the majority of over the air transmissions that take place in the United States were switched to the ATSC format. Developed in the early 1990's by Grand Alliance, the Advanced Television Systems Committee released a broadcast format that originally only supported High Definition (HD) programming, but has now been adjusted to support both standard and HD.
