What is the difference between pal and NTSC?
TV Broadcasting Technology is very difficult and even more complex than people thought and realize. There are some standards and necessary systems for television to work in a way they should be. All these procedures can be different and vary from country to country.
How did it come about and what is the NTSC System Like?
NTSC stands for National Television System Committee (NTSC); this is a system which was developed in the United States to be an Analog Broadcasting System for TVs. The system is now very old and it was established in 1941 and still broadcasting standards and it is the part of broadcasters in North America, Asia and South America. This system was not adopted in India.
This system has very sharp and rich features and all the features are striking. 525 resolution lines and with 480 fully visible images and the rest of the system is known as VBI (Vertical Blanking Interval) due to connectors and beams.
This system was specially made for those countries who use alternate current that counts 60 cycles in just one second, this process is also known as 60 Hz. In countries, where the type of this current is 50 Hz or 50 cycles in 1 second, there is a need to create the compatible TV system to avail this service and features.
This system is a complete and very efficient system and NTSC is eligible to produce over 16 million colors. Computers cannot use this system since Computer uses RGB which is Red Green Blue, computers are unable to use NTSC system because computer uses RGB to produce image. If you want to use this system in computer, then you have to use a converter so that you can use this system in computer otherwise it will be impossible for you to use this in computer.
How Did It come About and What is the PAL system Like?
PAL stands for Phase Alternating Line (PAL) and this system was widely spread in Europe. The founder of this system is a German Designer and Engineer named Walter Brunch. The company which sponsor this project was named as Telefunken. This system was created in 1963 but it was installed in 1967.
This PAL system has unique and great functions which are very great and efficient. This system has great characteristics such as high quality image, it has 625 line of resolution. In compare with NTSC system, this PAL system has 100 more line of resolution and that is why this produce higher quality image. This system has executive cycle of 50 Hz and this means that 50 cycles are performed in every second.
Americans Use NTSC, Everybody Else Uses PAL
In America, NTSC system is being used while in other countries they use PAL because the other system which is NTSC, is an analog color television system which is used in different regions of America including Central America, and other regions of South America as well.
PAL is a system which is based on analog which is used in Europe, Australia and other regions of Asia, remaining regions of South America and in Africa.
Both of these systems are very same and the only big difference is electrical usage. 60 Hz of electrical power is produced in north side of America. On the other side, the 50 Hz is a standard and this difference is huge than our thinking.
Why Power Makes Such a Big Difference Among Them?
If your TV operates at 60 Hz, then it does not mean that your TV will display 60 frames per seconds. Analog TVs uses Cathode Ray Tube which is also known as (CRT). It uses CRT technology and send beam of light at the backside of a screen but remember that these beams are not similar to projector. PAL is technically superior to NTSC.
Which One Should I Use?
The answer of many people will be NTSC. Many video converters and other editors give options to choose NTSC or PAL while compression or exporting an edited video. The format you should choose depend on the location and the viewers because different viewers use different system and this can be difficult to choose from.
If you are producing video and you know that your video will be watched globally means the viewers will be globally then NTSC will be a safer option for you by default. Most PAL VCRS and other DVD players can play NTSC easily while on the other hand, NTSC players cannot play PAL formatted videos.
What is the System of India?
There are many variations in PAL system as does the NTSC system. This was important and necessary for adaptation and other improvements. In India, this PAL system was adopted in the year of 1972 and the date was Feb 19.
The main change in this case was electric current because the system in India is 60 Hz which means that 60 cycles per second.
