What is the difference between NTSC, PAL, SECAM?

Author cavsi Category: Audio and Video Tags:

There are 3 main analog video standards in use around the world.

PAL (Phase Alternating Line)
NTSC (National Television System Committee)
SECAM (Séquentiel couleur à mémoire – Sequential Color with Memory)

Each standard is incompatible with the other two. Also, the equipment that demodulates the signal must be formatted for that signal.

Generally NTSC is used in North America, most of the countries in South America and Japan. PAL is the format for the UK and most European countries except France and parts of Eastern Europe which use SECAM. For example, a recording made in the France could not be played on an American VCR.

If you view video tapes that are from outside of the United States, or send videos abroad, you must first convert the tape to or from the foreign television standard.
