Abstract

PURPOSE: To shorten a communication time by inserting a skip pulse during a picture signal interval following to skip mark signals by performing modulation by the carrier of the picture signal, and by mixing the skip mark signal and skip pluse.
CONSTITUTION: At the transmission side, reader-scanner circuit 1 scans on an original line by line at a high speed in a phase-signal interval, and the contents of picture information obtained through the prior scanning are approved 4 in sequence; at the time when information on the line is skipped, sub-scanning skip pulses are generated as many as lines to be skipped. Here, the skip mark signal at timing right after a phase signal which corresponds to the 1st line of a series of continuous skip operations in modulated, skip pulses are inserted in the picture-signal interval following the skip mark signal, and modulation 3 is done by the carrier of the picture signal. Then, modulated skip mark signal and skip pulse are mixed and transmitted to the reception side, where demodulation is done. Consequently, the communication time can be shortened.
