On the transmitting side, there is provided a synchronizing signal generator for generating a horizontal synchronizing signal and a picture element clock signal. A regularly selective transmitter supplied with the output from the synchronizing signal generator to selectively remove picture elements of the video signal with a predetermined frame period. Thus, the video signal is formed into a plurality of sequences, which are and sequentially transmitted. On the receiving side, there is provided a synchronizing signal generator for generating a horizontal synchronizing signal and a picture element clock signal synchronized with those on the transmitting side, a frame memory for storing the video signal of one frame, and a movement detector for comparing the video signal sequence transmitted from the transmitting sides with those video signal sequences stored in the frame memory to determine whether the video signal of the transmitted sequence belongs to a moving picture or to a stationary picture and to produce a signal in accordance with the result of the comparison, the transmission station has no frame memory. The movement detector is included in the receiving station, therefore there is no need of transmitting a movement detecting signal.，下面是Video signal transmission system专利的具体信息内容。
1.
