The public telephone line has a bandwidth insufficient for the rapid transmission of video signals. A long time period is required therefore. The present invention improves this long transmission time. The freeze-picture transmission apparatus according to the present invention receives a plurality of video signals in a predetermined order. The received one is compressed and stored in memory. The read-out from the memory is done at a speed corresponding to a bandwidth of the transmission line. The compressed video signal read-out from the memory is transmitted to the reception unit. In the reception unit, the compressed video signal transmitted is once stored in another memory. The read-out from another memory is done at a TV scanning speed.
