THE ABOVE FORMATS ARE USED BY DIFFERENT COUNTRIES.
Most people using the pal video, U.S uses NTSC VIDEO to broadcast the video.france uses the SECAM video format.
abbreviations
NTSC--------(National Television System Committee)
PAL---------- (Phase Alternating Line)
SECAM-----(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.
This table illustrates the differences between the video standards:
NTSC M | PAL B,G,H | PAL I | PAL N | PAL M | SECAM B,G,H | SECAM D,K,K’,L | |
Lines/Fields | 525/60 | 625/50 | 625/50 | 625/50 | 525/60 | 625/50 | 625/50 |
Horizontal Frequency | 15.734 kHz | 15.625 kHz | 15.625 kHz | 15.625 kHz | 15.750 kHz | 15.625 kHz | 15.625 kHz |
Vertical Frequency | 60 Hz | 50 Hz | 50 Hz | 50 Hz | 60 Hz | 50 Hz | 50 Hz |

The difference is not the encoding of the video, but the means in which the video is transmitted.
PAL and NTSC are analog systems of transmission, which means that the growth of digital television around the globe will eventually render this comparison moot.
PAL (phase alternating line) video is the result of the European electrical grid, which is 50 hertz alternating current (Hz AC). Power circuits in North America are 60 Hz AC, which provides electricity at a higher frequency that is incompatible with PAL video. Because a new system needed to be designed, engineers tried to create a system that addressed deficiencies with the American video protocol. They called it National Television System Committee (NTSC).
The NTSC protocol calls for 525 scan lines (also called 480i), which is the number of pixel lines transmitted over a signal in standard definition. PAL signals read 625 scan lines (576i). Televisions read the signal and apply it to the number of pixel lines on their screen.
The lower scan-line number of NTSC leads to less color depth. The result is a less-than-true color broadcast, requiring tint control. This is why NTSC televisions are equipped with tint controllers and PAL are not.
