In November of the same year, Baird and Bernard Natan of Pathé established France's first television company, Télévision-Baird-Natan.
In 1931, he made the first outdoor remote broadcast, of The Derby.
In the receiver, a type of Kerr cell modulated the light and a series of variously angled mirrors attached to the edge of a rotating disc scanned the modulated beam onto the display screen. The 8x8 pixel resolution in this proof-of-concept demonstration was just sufficient to clearly transmit individual letters of the alphabet.
An updated image was transmitted "several times" each second.
The invention of the television was the work of many individuals in the late 19th and early 20th centuries.
Individuals and corporations competed in various parts of the world to deliver a device that superseded previous technology.A selenium photoelectric tube detected the light reflected from the subject and converted it into a proportional electrical signal.This was transmitted by AM radio waves to a receiver unit, where the video signal was applied to a neon light behind a second Nipkow disk rotating synchronized with the first.He also started work on the first color television.On March 25, 1925, Baird gave the first public demonstration of televised silhouette images in motion, at Selfridge's Department Store in London.Baird's system used the Nipkow disk for both scanning the image and displaying it.A bright light shining through a spinning Nipkow disk set with lenses projected a bright spot of light that swept across the subject.The first practical facsimile system, working on telegraph lines, was developed and put into service by the Italian priest Giovanni Caselli from 1856 onward.This was a spinning disk with a spiral pattern of holes in it, so each hole scanned a line of the image.By the 1920s, when amplification made television practical, Scottish inventor John Logie Baird employed the Nipkow disk in his prototype video systems.He created his prototype in a little village called Santa Cruz on the island of Trinidad where he was recovering from an illness.
