NTSC

The FCC had briefly approved a different color television standard, starting in October 1950, which was developed by CBS.[2] However, this standard was incompatible with black-and-white broadcasts. It used a rotating color wheel, reduced the number of scan lines from 525 to 405, and increased the field rate from 60 to 144, but had an effective frame rate of only 24 frames per second. Legal action by rival RCA kept commercial use of the system off the air until June 1951, and regular broadcasts only lasted a few months before manufacture of all color television sets was banned by the Office of Defense Mobilization (ODM) in October, ostensibly due to the Korean War.[3] CBS rescinded its system in March 1953,[4] and the FCC replaced it on December 17, 1953 with the NTSC color standard, which was cooperatively developed by several companies, including RCA and Philco.[5] The first publicly announced network television broadcast of a program using the NTSC «compatible color» system was an episode of NBC’s Kukla, Fran and Ollie on August 30, 1953, although it was viewable in color only at the network’s headquarters.[6] The first nationwide view of NTSC color came on the following January 1 with the coast-to-coast broadcast of the Tournament of Roses Parade, viewable on prototype color receivers at special presentations across the country. http://en.wikipedia.org/wiki/NTSC --37.190.52.119 18:38, 18 декабря 2012 (UTC)
