NTSC stands for National Television System Committee, and it refers to a television encoding system that was widely used in the United States and some other countries. It is a standard for the transmission and display of analog video signals.
The NTSC system was developed in the 1940s by the National Television System Committee, hence the acronym. It established the technical standards for black and white television broadcasting and later expanded to include color television. NTSC operates with a frame rate of 29.97 frames per second, and each frame is composed of 525 scan lines. The aspect ratio of NTSC video is 4:3.
In terms of video quality, NTSC is characterized by its relatively low resolution and limited color reproduction compared to newer digital video formats. The transmission occurs in analog form, meaning that the video signal is continuously varying rather than discrete digital data.
Despite its limitations, NTSC remained the standard for analog television in the United States for several decades and influenced television broadcasting worldwide. However, with the advent of digital television and high-definition formats, NTSC has been largely replaced by digital systems such as ATSC (Advanced Television Systems Committee) in the United States.
In summary, NTSC is a television encoding system that was widely used in the past, particularly in the United States, for transmitting and displaying analog video signals.
