NTSC stands for National Television System Committee. It is color encoding system that is responsible for setting up the visual quality and graphics of the content viewed on the TV. It is usually for the analog television. PAL stands for Phase Alternation by Line. All around the world these two systems are used for making the visual content visible and the only difference is that these two systems are found in different areas all around the globe. The basic difference between both systems is of their bandwidth, frame per second and aspect ratio.

What is NTSC?
NTSC stands for National Television System Committee it is a system that involves the quality of the visual content that is viewed on the TV. This system is applicable with the analog TVs and as well as digital televisions. It is distributed by region and covers a wide spread geographical area. The very first of NTSC based system was developed in 1941 that was primarily for the black and white analog TVs and did not support colored visual content. The digital television covering utilizing this particular system includes the whole of North America and South America, Along with it Burma, Japan, Taiwan, Pacific Islands and South Korea. This system is also used in the Philippines but only for analog-based television devices. NTSC system uses an aspect ratio of 720×480, and the frame rate of the visuals is 30 fps (Frames per second). Unlike PAL system it possesses manual color correction.
What is PAL?
PAL stands for Phase Alternation by Line. It is another widely used system that is responsible for the quality of the visual content delivered on the TVs. PAL is present in different areas and covers the rest of areas that does not involve NTSC. PAL system is moreover more facilitated and is based on the modern technology as compared to NTSC. The aspect ratio on PAL systems is 720X526, and the delivery of the frames is 25 fps. NTSC used manual color correction, whereas PAL unlike to NTSC possesses the automatic color correction options. PAL is more commonly used in countries like Australia, UK, Asia and many is many European countries as well such as Sweden, Denmark, etc. The very first of the PAL system was initially developed in Western Europe in 1950 and was proposed for few countries for testing purpose. PAL is now the most widely used visual content system on TV all around the globe.
