Abstract
A new method of transmission and reproduction of line images, e. g., drawings, is described which utilizes a cathode-ray tube for reproduction, the spot of which is made to trace out the lines of the image 20 or more times a second. The steps of the complete process are: first, the transcription of the line image into two tracks similar to sound-tracks on moving picture film; second, the production from these tracks of two varying potentials by means of photoelectric pick-up devices; third, the transmission of these potentials; and fourth, their application to the cathoderay deflector plates to effect reproduction. Satisfactory transmission of fairly complex images, e. g., animated cartoons, could be effected within a total band-width of 10,000 cycles.
