	Henry Valensi (Site not responding. Last check: 2007-11-04)
		Valensi moved to Paris in 1898 and studied at L’Ecole des Beaux Arts de Paris in the studios of Jules Lefebrve and Tony Robert-Fleury.
		In 1923 Valensi exhibited in Rome, the introduction of the catalogue was written by Marinetti, Valensi was consider a French Futurist.
		Valensi was the leader of the group of artists that he himself named the “Musicalistes.” Painting during the 1930s through the 1950s, the “Musicalistes” interpreted the rhythms of music in two dimensions through abstract shapes.

	Qwika - similar:NTSC
		Georges Valensi was a French telecommunications engineer who, in 1938, invented and patented a method of transmitting color images so that they could be received on both color and fl and white television sets.
		Rival color television methods, which had been in development since the 1920s, were incompatible with monochrome televisions.
		In telecommunication, a pilot is a signal, usually a single frequency, transmitted over a communications system for supervisory, control, equalization, continuity, synchronization, or reference purposes.

	YUV - Encyclopedia, History, Geography and Biography
		As most actual uses of RGB->YUV are in integer math, it's often convenient to use a fixed-point approximation.
		The primary advantages of luminance/chrominance systems such as YUV, and its relatives YIQ and YDbDr, are that they remain compatible with fl and white analog television (largely due to the work of Georges Valensi).
		The Y channel saves nearly all the data recorded by fl and white cameras, so it produces a signal suitable for reception on old monochrome displays.

	The Television: Colored-up.
		The problem that cropped up was that the public was not willing to churn out additional cash to buy color TVs since they had just recently purchased expensive fl and white ones.
		In 1938, Georges Valensi suggested that it should be possible to transmit color programs in such a way that fl and white television sets would also be able to recognize the signals and fl and white viewing be possible.
		This created a necessity to have some form of signal usable by a fl and white receiver and not just 3 signals, one for each of the primary colors.

	Living In One World
		By the early years of the 20th century reliable electrically-powered calculators and electronic vacuum tubes were available, but it was not until 1936 that Konrad Zuse developed the first mechanical computer and then relay-operated machines (relays are switches operated by electromagnets).
		In the USA George Stiblitz completed the first relay computer in 1939, while working for Bell Laboratories and in the same year John Atanasoff introduced a semi-digital computer.
		Other key developments in the 1800s were the introduction of binary logic by the English mathematician George Boole from 1847; and the intro-duction of punched cards for use in electrically-powered calculating machines in the 1880s by the American, Herman Hollerith, whose company eventually became the computer giant IBM.

	DVB - The History of Television
		George Carey proposed a system based on the exploration of every point in the image simultaneously: a large number of photoelectric cells are arranged on a panel, facing the image, and wired to a panel carrying the same number of bulbs.
		Equipment that was easier to manipulate was used by the BBC for the coronation of His Majesty King George VI in 1937 and, the following year, for the Epsom Derby.
		In 1938, Georges Valensi, in France, proposed the principle of dual compatibility:

	NTSC - Biocrawler (Site not responding. Last check: 2007-11-04)
		Because the NTSC frame rate is higher, it is necessary for video conversion equipment converting to NTSC to interpolate the contents of adjacent frames in order to produce new intermediate frames; this introduces artifacts, and a trained eye can quickly spot video that has been converted between formats.
		For backward compatibility with fl and white television, NTSC—in this area the terminology NTSC is technically correct—uses a luminance-chrominance encoding system invented in 1938 by Georges Valensi.
		Luminance is essentially the original monochrome signal, while chrominance carries color information.

		For backward compatibility with fl and white television, NTSC uses a luminance-chrominance encoding system invented in 1938 by Georges Valensi.
		Luminance (derived mathematically from the composite color signal) takes the place of the original monochrome signal.

		After having gone _ far, George did not want to turn back.
		The longest extension ever granted was to Georges Valensi; his 1939 patent for color TV re- ceiver circuitry was extended until 1971 because for most of the patent s normal life there was no colour TV to receive and thus no hope of reward for the invention.
		Because a patent remains permanently public after it has terminated, the shelves of the li- brary attached to the patent office contain details of literally millions of ideas that are free for any- one to use and, if older than half a century, sometimes even re-patent.
