What is the difference between Pal and NTSC?

TV broadcasting technology is more complex than people realize. There are systems and standards necessary for television to work the way we are used to, and these procedures may differ from country to country.

Differences between PAL and NTSC System

To know the difference between these two transmission systems it is convenient to present the history and the details of each of them. Check out!

How did it come about and what is the NTSC System like?

The National Television System Committee (NTSC) system was developed in the United States to be an analog broadcast model for televisions. The system is old, born in 1941, still in broadcasting standard, and is part of broadcasters in North America, South America, and Asia. Interestingly, this system was not adopted in India.

The NTSC system has very sharp and striking features, such as 525 lines of resolution, with 480 fully visible images, while the rest of the system is due to the connectors and beams called VBI (Vertical Blanking Interval).

The NTSC is a system made for countries that use an alternating current that counts 60 cycles in one second, which can also be called 60 Hertz (Hz). In countries where the type of electric current is 50 Hertz or 50 cycles per second, there was a need to create compatible television systems.

NTSC is a complete and very efficient system capable of reproducing over 16 million different colors on a television. NTSC is not compatible with computers because computers use RGB (Red, Green, and Blue) system boards to form their images. To do so, you need to use converters.

How did it come about and what is the PAL System like?

The Phase Alternating Line (PAL) system has been widespread in Europe. Its creator is a German designer and engineer named Walter Brunch. The project sponsor company was Telefunken. The PAL system was created in 1963 but was installed in 1967.

The PAL system has very determining characteristics, such as a very high-quality image, totaling 625 lines of resolution. Compared to the NTSC system, there are 100 more lines in the PAL system and therefore it has higher quality in its images. The execution cycle is 50Hz, which means that 50 cycles are performed every second, the same as NTSC.

What is the system of India?

The PAL system has variations, as does the NTSC system. This was necessary for adaptations and improvements to be conceived. In India, the PAL system was adopted in 1972, on February 19.

The main change in this case was the adaptation of the electric current, since in India the system is 60 Hz, which corresponds to 60 cycles per second. The name of the variation of the PAL system that operates in India is PAL-M.
