In 1926, British engineer John Beder made an experimental television broadcast using the method of mechanical scanning. Eleven years later, the British BBC company successfully developed and produced a black-and-white television system with electronic scanning, and officially broadcast black-and-white television programs. Around 1950, the United States carried out a lot of research work on color television on the basis of the development of black-and-white television, and in the autumn of 1953, the NTSC color television system compatible with black-and-white television was determined, thus completing the transition from black-and-white television to color television.
In 1956, Dr. Henri Di Falessi of France proposed another color television system, SECAM system, which was improved on the basis of the NTSC system.
In 1960, the engineers of the West German company Delfürtuen, Hull, Berluch, proposed the PAL system, which basically retained the advantages of the NTSC system and took some improvements. In 1966, West Germany and the United Kingdom established the PAL system as the national standard.
