The two main types of analog television broadcast signals are NTSC and ATSC. Both systems have been used in the United States, Canada, Mexico, South Korea, Japan, Taiwan, and other countries. NTSC is an abbreviation for National Television System Committee.
ATSC is an abbreviation for Advanced Television Systems Committee. The main difference between NTSC and ATSC is that NTSC uses a 4:3 aspect ratio while ATSC uses a 16:9 aspect ratio. NTSC also has a frame rate of 30 frames per second (FPS) while ATSC has a frame rate of 59.94 frames per second (FPS). In addition, NTSC uses composite video while ATSC uses digital component video.
What is NTSC?
NTSC, or National Television System Committee, is the analog television system that was used in North America from 1941 until 2009. NTSC was developed by the Radio Corporation of America (RCA) and is based on a system that was originally used in mechanical television receivers. NTSC was commonly used in the United States, Canada, Mexico, Japan, and other countries. NTSC has a refresh rate of 60 Hz and uses an interlaced scanning format. NTSC is not compatible with PAL or SECAM, which are the other two major television systems. In 2009, NTSC was replaced by ATSC as the standard for digital television in North America.

Difference between NTSC and ATSC
NTSC and ATSC are two different television broadcast standards. NTSC, which stands for National Television Standards Committee, is the analog broadcast standard used in the United States. ATSC, which stands for Advanced Television Systems Committee, is the digital broadcast standard used in the United States. NTSC is incompatible with ATSC, so a TV that can only receive NTSC signals will not be able to receive ATSC signals.
The main difference between NTSC and ATSC is that NTSC is an analog signal while ATSC is a digital signal. NTSC signals are transmitted using amplitude modulation while ATSC signals are transmitted using quadrature amplitude modulation. ATSC also uses 8VSB modulation while NTSC uses FM modulation. Another difference between NTSC and ATSC is that NTSC has a 4:3 aspect ratio while ATSC has a 16:9 aspect ratio. Finally, NTSC has a resolution of 720×480 while ATSC has a resolution of 1920×1080.
Conclusion
The major difference between NTSC and ATSC is that ATSC uses MPEG-2 compression, while NTSC does not. This results in a higher quality image with less noise for ATSC broadcasts. However, there are still many TVs out there that only support NTSC signals, so it is important to be aware of both standards when planning your broadcast strategy.
