Telecommunications for all.
Introduction Transmitting pictures via the telephone network is an old gimmick.
He used a technology very much like the one used later by the German physicist Arthur Korn - the father of the modern telefax. Transmitting moving images is a much later issue, because of the much more advanced technology required. Instead, techniques of processing the pictures have been developed, thus allowing for transmission of moving images via ordinary telephone lines. Only a fraction of the information can be transmitted under such circumstances, but with intelligent signal processing moving images of useful quality can be received. The technology is interesting for many purposes.
