<p>PURPOSE: To reduce the deterioration of quality becoming a fault and time delay as much as possible by minimizing delay time at the time of transmitting the moving picture of a low data rate. CONSTITUTION: The field picture of a picture part where a picture area to be transmitted changes is coded on a transmission side, it is transmitted through a transmission channel and is decoded on a reception side. The decoded field picture is inserted in accordance with the picture parts of a reproduction picture and it is substituted for a comparatively old field picture which is transmitted before the part. Then, it is used before partial update. Algorithm delay and storage delay in a television camera used in track and field are minimized, a continuous motion process is given to an observer and impression is made effective, for example. When time required for coding or decoding one picture is equal for all the pictures, coding time CP and decoding time dp for avoiding the loss of calculation ability are made constant and the time area between the pictures is set to be 1/f.</p> |
