Method and apparatus for encoding, transmitting, receiving and de-coding information

摘要

A clear language dictionary of items of information to be transmitted is provided for composing messages and is also electronically impressed in first memory elements of sending and receiving computers. Each item of the dictionary is equated to a different octal number and the several octal numbers are impressed in second memories of both of the computers. The sending computer converts each selected item to its equated octal number, and then converts each digit of the equated octal numbers to successive groups of binary digits 0-0-0 to 1-1-1 taken from a color code which is impressed in third memories of both computers and in which the first digit of each group is equated to a first basic color, the second digit is equated to a second basic color, and the third digit is equated to a third basic color. Each group of binary digits is transmitted as a color coded group from the third memory of the sending computer, either as a binary color group on television or as optical colors singly or in combinations of colors. Three optically shielded light sensitive color receptors at the receiving station re-convert the color pulses to binary digit groups that are fed to the memory of the receiving computer for reverse de-coding and actuation of a printer to reproduce the message sent.
