Abstract

PURPOSE: To prevent the bad influence to the display by circulating once the reading of the character information of the main memory when the synchronizing shift is generated without repeating it.
CONSTITUTION: The synchronizing correction circuit 300 is disposed at the back step of the synchronizing separation circuit 4. When the phase shift of the phase signal is produced because of the change-over of the television signal, if the vertical synchronizing signal is introduced before the reading of one field of the main memory 17 is completed, the correction vertical synchronizing signal neglecting this is outputted. When the horizontal synchronizing signal is introduced before the reading for one scanning line of the character information of the main memory 17, the correction horizontal synchronizing signal to neglect it and be produced after the completion of the reading is outputted. Accordingly, even if the the hoirzontal or the vertical synchronizing signals of the transmission signal produce the phase shift due to any reason, the influence of the reproduced image surface of the character signal can be prevented.
