The tint control is normally set by sight to create satisfactory skin tones in a picture. The range of adjustment typically allows these colors to be adjusted from a green to a magenta tint. Television sets produced in recent decades typically include a (sometimes non-defeatable) distortion of the color decoding spectrum, to minimize the visual ...

A typical modern set-top box, along with its remote control - pictured here a digital terrestrial TV receiver by TEAC. A set-top box (STB), also known as a cable box, receiver, or simply box, and historically television decoder or a converter, [1] is an information appliance device that generally contains a TV tuner input and displays output to a television set, turning the source signal into ...
Each frame corresponded to one of the RGB primary colors. This method is compatible with black and white NTSC, but incompatible with color NTSC. In fact, even NTSC monochrome TV compatibility is marginal. A monochrome set could have reproduced the pictures, but the pictures would have flickered terribly. The camera color video ran at only 10 ...
Test cards typically contain a set of patterns to enable television cameras and receivers to be adjusted to show the picture correctly (see SMPTE color bars).Most modern test cards include a set of calibrated color bars which will produce a characteristic pattern of "dot landings" on a vectorscope, allowing chroma and tint to be precisely adjusted between generations of videotape or network feeds.
Rendition of SD ECR-1-1978 color bars Colors are only approximate due to different transfers and color spaces used on web pages and video (BT.601 or BT.709). SMPTE color bars are a television test pattern used where the NTSC video standard is utilized, including countries in North America.
In NTSC, its frequency is exactly 315/88 = 3.579 54 [a] MHz with a phase of 180°. PAL uses a frequency of exactly 4.43361875 MHz, with its phase alternating between 135° and 225° from line to line. Since the colorburst signal has a known amplitude, it is sometimes used as a reference level when compensating for amplitude variations in the ...
The vacuum-tube electronics used in televisions through the 1960s led to various technical problems. Among other things, the color burst phase would often drift. In addition, the TV studios did not always transmit properly, leading to hue changes when channels were changed, which is why NTSC televisions were equipped with a tint control.
