11 Facts About NTSC

In 1953, a second NTSC standard was adopted, which allowed for color television broadcast compatible with the existing stock of black-and-white receivers.

Since the introduction of digital sources the term "NTSC" might be used to refer to digital formats with number of active lines between 480 and 487 having 30 or 29.

NTSC standard was used in most of the Americas, Myanmar, South Korea, Taiwan, Philippines, Japan, and some Pacific Islands nations and territories .

NTSC standard has been adopted by other countries, including some in the Americas and Japan.

Japanese NTSC never changed primaries and whitepoint to SMPTE "C", continuing to use the 1953 NTSC primaries and whitepoint.

Backward compatibility with black-and-white television, NTSC uses a luminance-chrominance encoding system invented in 1938 by Georges Valensi.

In NTSC, chrominance is encoded using two color signals known as I and Q in a process called QAM.

The NTSC signal includes a short sample of this reference signal, known as the colorburst, located on the 'back porch' of each horizontal synchronization pulse.

In CRT televisions, the NTSC signal is turned into three color signals called Red, Green and Blue, each controlling that color electron gun.

Mathematically for NTSC this is relatively simple as it is only needed to duplicate every fourth frame.

Use of NTSC coded color in S-Video systems, as well as the use of closed-circuit composite NTSC, both eliminate the phase distortions because there is no reception ghosting in a closed-circuit system to smear the color burst.
