Color (television)

Color is an invention that was introduced in the Netherlands on September 21, 1967 and in Belgium on 1 January 1971. The Netherlands Antilles were color TV in 1973, Suriname followed in 1977. In the 70s of the 20th century color to a large audience and affordable the color gradually supplanted theblack and white - television .

Ten years after the introduction was, according to the CBS 52% of Dutch households own a color device. In 1978, already 61% of households own a color TV. In 1977, the last NIS studio in The Hague made suitable for broadcast in color.

The television reporter gave the benefit of black-witkijkers at a football game until about the early eighties by the football teams that played in light and in dark shirts.

The color systems are fully compatible with monochrome. A color transmission is also to receive a black-white television, of course, without color, without technical modifications. Also, the reverse is the case.

In Europe, a system is used with the name of PAL, while in America an older system, NTSC , is used. France has another system called SECAM, among other things used by Eastern European countries. The differences in these three systems consist primarily of how the problem of the gradients of the color spectrum to be solved by small phase differences in the reception signal. These phase differences are often due to the inevitable imperfections in the received antenna signal that the electromagnetic waves of the television signal are often reflected by buildings and other obstacles. This causes the color image, if no control measures are taken against, color errors can for example prevent a pink face will have a greenish tint.

PAL and SECAM each have a solution for this problem. In NTSC color errors must sometimes be corrected by hand. NTSC is therefore considered to be inferior, but NTSC is indeed a technological feat. The NTSC system, however, developed much earlier, while the Europeans have waited until the technology that was more advanced and could use the experiences of the American system.

The picture tube of a color is significantly different from that of a black-and-white device, as well as the recording devices. Internally, everything is repeated three times: once for 1 red, 1 time for blue and 1 time for green . With these three colors can be blended to the human eye all visible colors, according to the RGB system.
