An improved RCA/NBC color system submitted in July 1953 became the industry standard chosen by the Federal Communications Commission (FCC) in December 1953. Goldmark and others have pointed out that the CBS color wheel system did provide better picture quality than RCA’s system, but the compatibility problem proved its downfall. Brown and others) was compatible with existing black and white TVs. In the end, another “compatible color” technology developed for RCA and NBC (by a team led by Richard Kell, George H. Although CBS did broadcast in color with the Goldmark system in 1950–1951, the incompatibility problem remained for the about ten million receivers that were then in use. After the end of the war, Goldmark again took up the development of color television using the field sequential method. World War IIĭuring World War II, Goldmark was put in charge of a group developing electronic counter measure receivers. On December 2, 1940, the system broadcast the first live color TV images on experimental CBS channels. The system transmitted on 343 lines, about 100 less than a black and white set, and at a different field scan rate, and thus was incompatible with television sets currently on the market without an adapter. In the first public demo, it projected colorful images of flowers, a red boat sailed into a sunset and a girl chased a ball. The system, first demonstrated on August 29, 1940, and shown to the press on September 3 used a rapidly rotating color wheel that alternated transmission in red, green and blue at the rate of twenty pictures a second.
After his return to the United States, he set about creating a prototype color television. He was fascinated by the color images and soon became enthusiastic about the idea of color images on television. During a postponed honeymoon with his second wife in Montreal in the spring of 1940, Peter Carl Goldmark attended a screening of the film Gone with the Wind in Technicolor. In addition to his work on the LP record, Goldmark developed field-sequential color technology for color television while at CBS.
In 1948, Goldmark invented the plastic long-playing record, which soon replaced the shellac record. In the following years, he was instrumental in developing the long-playing microgroove 33-1/3 rpm phonograph disc, the standard for incorporating multiple or lengthy recorded works on a single disc for two generations. From 1945 to 1948, he developed the filler-free compound (made of PVC and PV acetate), which reduced the noise of the records in addition, the speed could be reduced from 78 to 33⅓ min-1. In 1936, Goldmark joined CBS Laboratories as Chief Television Engineer, and one year later he became a naturalized citizen of the U.S. Kaltenborn of CBS, who convinced him to move to the United States. īack in Vienna, he eventually met radio correspondent H. He later hoped to work together with John Logie Baird but was turned down for a job after meeting Baird for lunch in London. Goldmark received his first exposure to television already in 1926 while in graduate school in Vienna. In 1931, he earned his PhD in physics in Vienna. Peter’s interest in radio led him to study engineering, but he was unable to register at the Technische Hochschule in Vienna and spent a year at the Technische Hochschule in Berlin. At the end of World War I in 1919, the family moved to Vienna to escape the communist regime that took over Hungary. But, from his autobiography, we that he know grew up in a classical musical environment, which had strong influences on his decisions in later life. Peter Carl Goldmark was born in Budapest, Hungary, and little is known about his early years. Goldmark also also developed the 33-1/3 LP phonograph that greatly increased the playing time of records, which revolutionized the recording industry. While working for Columbia Broadcasting System (CBS), he developed the first commercial color television system (1940), which used a rotating three-color disk. On December 2, 1906, German-Hungarian engineer Peter Carl Goldmark was born. Patent diagrams of CBS field-sequential color system: Fig.
