Abstract

PURPOSE: To reduce sharply the disarray of reproduced character patterns by transmitting a prescribed protection information corresponding to the action of display control information separately and, at reception of the display control information, correcting the loss of signs and errors on the basis of the protection information.
CONSTITUTION: A bucket detection circuit 22 supplies an error discrimination result to a correction control circuit 23 on the basis of the data of a sign data error detection result from a bit relocation circuit 5. The circuit 23 reads out control data for format protection corresponding to the bucket number of the received bucket from an F bucket memory 9 by the command from the circuit 22 and supplies data to a display coordinate specification register 17, a character pattern specification register 15 and a character pattern set specification register 16 on the basis of the read data to correct each data. Thus even if losses and errors are detected in data transmission of normal buckets, appropriate character patterns can be displayed.
