Fultograph Print
image:fultograph_print.jpg, A Fultograph image, 65×129mm. The fultograph was an early, clockwork image-receiving device, similar in function to fax machines. It took signals from the loudspeaker socket of a radio receiver and used an electrochemical process to darken areas of sensitised paper wrapped on a rotating drum. Invented by Otho Fulton, the system was used briefly in the late 1920s to broadcast images to homes by radio. The machines themselves were expensive (Pound sterling, £22 15''Pound sterling#Subdivisions and other units, s'' 0''Pound sterling#Subdivisions and other units, d'' in 1928) and required a good receiver to operate.The fultograph, Transdiffusion.org retrieved on: August 13, 2007 The BBC broadcast Fultograph images in 759 programmes between 1929 and 1932.

Fax Machine
Fax (short for facsimile), sometimes called telecopying or telefax (the latter short for telefacsimile), is the telephonic transmission of scanned printed material (both text and images), normally to a telephone number connected to a printer or other output device. The original document is scanned with a fax machine (or a telecopier), which processes the contents (text or images) as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system in the form of audio-frequency tones. The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy. Early systems used direct conversions of image darkness to audio tone in a continuous or analog manner. Since the 1980s, most machines modulate the transmitted audio frequencies using a digital representation of the page which is compressed to quickly transmit areas which are all-white or all-black. Fax machines were ubiquitous in office environments in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
