Abstract
A picture encoding and decoding technique for enabling random accessing. Using a prediction picture signal formed by only locally decoded signals of an intra-coded first field, a second field making up a frame along with the above-mentioned first field is encoded. If the second field making up a frame along with the above-mentioned first field is encoded using a prediction picture signal formed from the local decoded signal of a field belonging to a temporally previous group, a flag indicating that encoding has been made using the local decoded signal of the field belonging to the temporally previous group is encoded.
