Documentation of the characteristics of NTSC. NTSC is defined primarily in FCC Part 73 technical specifications. Many of its characteristics are defined in EIA-170A. NTSC is also defined by the CCIR.
NTSC is a living standard; as problems with it are discovered, they are corrected.
For example, a former EIA standard, RS-170, omitted any phase relationship between luminance and chrominance timing, resulting in blanking problems. EIA-170A defines that relationship (called SC/H for subcarrier to horizontal phase relationship). See also True NTSC.

K2T is a weighted function of the amplitude and time of the distortions occurring before and after the 2T pulse. In practice, a graticule is almost always used to quantify this distortion. Different countries and standards use slightly different amplitude weighting factors. The figure below shows a typical waveform monitor K Factor graticule display. The outer dotted lines at the bottom of the graticule indicate 5% K2T limits. See the discussion on Pulse to Bar Ratios.

Calculation of this parameter requires the measurement of the pulse and bar amplitudes. Kpulse/bar is equal to: 1/4

The CCIR designation for 525 scanning-line/30 frame-per-second television.
U.S. color television is internationally designated NTSC-M. The M standard is the world’s second oldest (the oldest was a 405-line/25 frame British standard, no longer broadcast).
