Abstract

PURPOSE: To perform the picture transmission between different types of units, by selecting and recording either of the picture signal decoding the reception code or its differentiation signal according to the number of black video elements of each scanning line.
CONSTITUTION: The video signal decoded with the decoder 13 is stored in the line memory 31 every one scanning line and inputted to the black video element count circuit 32 at the same time to count the number of black video elements in the scanning lines. After the end of count, the video signal read out from the line memory 31 is inputted to the selector 34 as it is, while the differentiation signal via the differentiation circuit 33 is inputted to the selector 34. The selector 34 is controlled with the output of the black video element count circuit 32, and if the number of black video elements in the scanning lines exceeds a given number, the differentiation signal is selected and transferred to the recorder 14, and otherwise, the original video signal is performed. The receiver obtaines the information related to the recording and processing speed of the transmitter with the transmission control procedure in advance to perform selective control.
