What is NTSC?

NTSC mainly refers to the older analog signal that was adopted by the United States in the 1940s. However, it is largely phased out under digital ATSC broadcasting. NTSC is considered inferior to ATSC because it is not capable of providing high-quality HDTV images or widescreen formats and also does not retain the highest audio. The NTSC has a committee on the National Television System, which was started by the United States in 1940. It was introduced under the original standards for analog television. 

After its arrival, differences between the various TV companies ended and the system was standardized. The system was later changed from black and white to color TV, which became possible in 1953 and was updated. Apart from America, this system was also used in Canada, America, Japan, and many Asian countries, the Caribbean, South America, etc. In 2009, it was discontinued in the US. It was gradually discontinued in Canada and most countries by 2011.

NTSC stands for National Television System Committee. It is the older version of television analog. NTSC only allows encoding two color signals which are I which is known as I-Phase and Q which is known as in Quadrature. This process is called QAM. After this, NTSC allows color subcarrier for color television. 

What is ATSC?

ATSC is a type of OTA signal introduced by the United States. It is many times better and better than the old system. It has been designed in such a way that all the old gaps can be filled. It has also brought high-quality widescreen, HDTV picture, and audio quality by enhancing the quality. Along with this, all the qualities of theatrical effect have been provided in it.

Using analog TV requires the aid of a converter if the digital signal is to be carried away. But all new TVs covered by the FCC already have an ATSC tuner built into the TV so a separate tuner isn’t needed. ATSC stands for Advanced TV Committee, the group that replaced NTSC in 1982 to rectify its shortcomings and convert it into an improved version, which was done by the United States itself.

ATSC stands for advance television system committee. It is capable to carry multiple channel information in a single stream. ATSC support different display resolution. It allows the 1080s and 720p video formats. ATSC requires less bandwidth for HDTV quality. ATSC can carry 6 SD video streaming and gives a wide range of screen formats which is up to 16:9. So overall we can say that ATSC is gradually replacing NTSC because it is the updated version.
