<p>In an encoder (1, 2; Fig. 1), an input picture of a non-interlace structure is sampled by down sampling to form an interlace picture,and the interlace picture is encoded. The encoded data are decoded to form an interlace decoded picture, and the interlace decoded picture is sampled by up sampling and utilized as a predictive picture upon encoding of the non-interlace input picture. In a decoder (7, 4; Fig. 2), a bit stream corresponding to an interlace picture of a low resolution is decoded into an interlace decoded picture. The interlace decoded picture is sampled by up sampling and is utilized as a predictive picture upon decoding of a bit stream corresponding to a non-interlace picture of a high resolution. <IMAGE></p> |
