Henri De France

Henri de France was an influential French television engineer. He was the author of the 819 line standard, the inventor of SECAM and apparently behind the HD-MAC high-definition standard. On December 6, 1931, he founded the Compagnie Gnrale de Tlvision in Le Havre and develops television sets using a vertical definition of 60 lines. Another French pioneer of the time is Ren Barthlemy. In February 1932, de France makes several transmissions over a distance of 7 kilometers from the Radio-Normandie station in Fcamps. His signals can be received by a few people located at over 100 kilometers away. In October 1932, he obtains a definition of 120 lines. In 1956 he patents the SECAM color television system. On October 1, 1967 at 2:15pm CET, la deuxime chane switched broadcast from black and white to color using SECAM. Died in January 1996. Interred at Jarnac, the same town where former president Franois Mitterrand lies. The public passage near France Tlvisions buildings in Paris is named Esplanade Henri de France.
