Abstract
PURPOSE:To transmit the information with high quality, by transmitting a picture and a voice at intervals of 1 field in case of a quick motion scene, and on the other hand, transmitting a picture and a voice at intervals of 1 frame in case of a slow motion scene. CONSTITUTION:A continuous video signal is digitized by the A/D converter 1, and is written into the frame memories 2, 2' in due order. A continuous voice signal is digitized by the A/D converter 5, and is stored in the buffer memories 6, 7 in due order. On the other hand, whether the picture motion is large or not between the adjoining frames is decided by the motion detection circuit 4. In case it has been decided by the motion detection circuit 4 that the motion is quick, a picture and a digitized voice are transmitted reciprocally at intervals of 1 field, and on the other hand, in case it has been decided that the motion is slow, a picture and a digitized voice are transmitted reciprocally at intervals of 1 frame.
