Abstract
PURPOSE: To enable the addition of redundancy bit, by performing the identification of line synchronous signal in high speed facsimile signal through the insertio of codes corresponding to the length 0 as the redundancy bit with a required number, when the coding of specified video information is finished.
CONSTITUTION: After the scanning signal of picture is converted into binary electric signal with the video reader 1 and it is ones tored in the input buffer memory 2, the signal from the memory 2 is coded at the coder 3 and outputted to the output terminal via the output buffer memory 4. The counter 6 and the dummy 7 are provided with the output of the coder 3 with this circuit constitution. Further, the counter 6 counts the number of bits per one line and if the count value is less than the specified value, constitution is taken that the coder 7 is driven until the specified value is exceeded. The code of run length having length 0 outputted with the coder 7 is repetitively added to the end part of the video signal of the buffer 4.
