Abstract
The method of electro-optically scanning a picture with a multiple electrical optical scanning head which can be laterally moved across the picture and the outputs of the multiple scanning head are supplied to a first group of shift registers so that individual lines of scanned information will be stored in individual shift registers. After the k lines of information have been scanned and stored in the first group of shift registers the scanning element is shifted to scan additional lines and the output of the multiple scanning device is supplied to a second plurality of shift registers to store information in this group of lines. When information is being written in the second group of shift registers the first group of shift registers are connected to a transmitter to serially transmit line by line the stored information. While information is being written into the first group of shift registers the second group of shift registers are connected to a transmitting medium to transmit the stored information line by line. A similar receiver with third and fourth group of shift registers is used to reproduce the information at a receiving site.
