441 lines

441 lines, or 383i if named using modern standard, is an early electronic television system. It was used with 50 interlaced frames per second in France and Germany, where it was as an improvement over the previous 180 lines system. In North America it was used by RCA with 60 frames per second from 1938 to 1941.

Use in Italy

Broadcasts using the system began in Italy in 1939 with regular services from Rome and Milan using 2 kW power on the frequency 45 MHz

North America

Field tests in Los Angeles on various line systems began in 1936, and North America had adopted RCA's 441-line system by 1938. The following year the first TV receivers were sold on a very limited basis, mostly in New York. Its manufactures included RCA, General Electric, DuMont, and Andrea. The 525 line System-M replaced the 441 line standard on July 1, 1941.
