The video data of an image sequence are encoded and decoded section by section, with each nth key frame data field being transmitted as completely as possible. From two adjacent key frame data fields, n-1 phantom image data fields are calculated at the transmitting and receiving ends taking into account n-1 motion fields. Further, n-1 difference image data fields are determined at the transmitting end and transmitted together with the key frame data fields. At the receiving end, the original sequence of data fields is reconstructed from the transmitted data fields by recalculation of the motion fields.
