Color television receiver "Rainbow".
Color TVsDomesticThe television receiver of the black-and-white image Raduga "has been experimentally produced by the Leningrad plant named after Kozitsky since 1954. In Leningrad, for experiments on the introduction of color television since the spring of 1954, a small number of experimental television receiver" Rainbow "was produced. It was an electronic television set for reception of a black-and-white image with mechanical color production by means of synchronous rotation with the transmitting center of an electric motor with light filters of red, blue and green colors combined on a common disk with an electric motor and installed in front of the screen inside the apparatus. started working on the third meter channel in 1955. The TV was modernized several times. In Moscow, views were organized to demonstrate the capabilities of color television in specially created ateliers. In 1956, all these experiments, as unpromising, were completed. I have no yes data on the modernization of the model, but in the article cited and photographs from the magazine "Soviet Union" No. 6 for 1954, the TV, although it remained in the same building, has clearly undergone significant changes. Judging by the photographs, it was already a TV with a rectangular picture tube and no rotating color filters. Maybe I'm wrong, and these are only photos retouched by the editorial staff of the magazine. This is how television is described in the magazine "Soviet Union": Millions of Soviet people watch television. Television broadcasting is becoming more and more widespread in the USSR. Along with the construction of new television centers, work is underway to create new broadcast television centers and equipment for the exchange of television programs between cities. In the past, in 1953, TV sets of new models went on sale: Temp, Avangard, Sever, Zenit, Zvezda. And recently a TV set of the Ekran brand has been released. A projection receiver with a 1 square meter screen is being developed. Television equipment with a 3x4 m screen has been created, thanks to which hundreds of viewers will be able to watch the program simultaneously. Soviet designers are improving new models of domestic television sets and transmission equipment. The sensitivity of the receivers increases, a switch for five television channels is introduced in all televisions, the VHF range is added. In 1954, enterprises of the domestic radio engineering industry manufactured experimental equipment for color television transmissions. Design engineers N.S. Belyaev, P.I. Korshunov and V.G. Semyonov created transmitting and receiving television equipment for color images, as well as a new experimental TV `` Rainbow ''. The first broadcasts gave good results. Nowadays, test broadcasts of performances, concerts and films in color are held regularly, twice a week. At the same time, engineers are working to ensure the compatibility of color and b / w images. For their reception, a device that is universal in terms of the combination system is already being designed.
