Abstract

PURPOSE: To prevent the lowering in the video quality, due to jitter by detecting the center of each bit of the video signal from the transmitter section read in and by performing phase adjustment again when the detection point is shifted by a given amount.
CONSTITUTION: The crystal oscillator 1 at the reception side is a high oreder colck source, the output is divided by 16 with the counter 2, generating the recording clock, and one circulation is made with n counts corresponding to the number of bits of one line at the counter 3. Further, the video signal read in with the transmitter is sampled with the period the same period as the recording clock at the reception side, the faxsimile signal E received at the reception side is differentiated 4, setting the counters 2 and 3 via the gate 5. Further, the output decoding 6 the output of the counter 3 controls the gaste 5. Further, phase alignment is made so that the center of each bit of the signal E can be detected, and when the detected point is shifted by a given amount, the lowering in the video quality due to jitter can be prevented
