49 Facts About Electronic television

Alternatively Electronic television signals are distributed by coaxial cable or optical fiber, satellite systems and, since the 2000s via the Internet.

Until the early 2000s, these were transmitted as analog signals, but a transition to digital Electronic television was expected to be completed worldwide by the late 2010s.

Electronic television published an article on "Motion Pictures by Wireless" in 1913; transmitted moving silhouette images for witnesses in December 1923; and on 13 June 1925 publicly demonstrated synchronized transmission of silhouette pictures.

Meanwhile, in the Soviet Union, Leon Theremin had been developing a mirror drum-based Electronic television, starting with 16 lines resolution in 1925, then 32 lines and eventually 64 using interlacing in 1926.

Only a limited number of holes could be made in the disks, and disks beyond a certain diameter became impractical, image resolution on mechanical Electronic television broadcasts was relatively low, ranging from about 30 lines up to 120 or so.
