A video encoder () for coding moving pictures comprising a buffer () with a plurality of memory areas capable of storing frames composed of top fields and bottom fields, a motion estimation unit () operable to code, field by field, inputted pictures performing moving estimation and moving compensation by referring, field by field, to the picture data stored in a memory area, a motion compensation unit (), a subtractor (), a transformation unit () and a quantization unit (), a memory management unit () operable to manage, frame by frame, a plurality of memory areas, an inverse quantization unit () and inverse discrete cosine transform unit () operable to decode picture data in coded fields and store the picture data in the decoded field in any of the plurality of memory areas under the management by the memory management unit ().

Moving picture coding apparatus and moving picture decoding apparatus

A decoder according to the present invention includes: an obtainment unit which obtains additional information that includes a motion vector indicating a motion of an image in the first video data, and stream data that is coded data of the second video data which has the same content as the first video data and which has the lower resolution than the resolution of the first video data; a decoding unit which decodes the stream data into images of the second video data; and a conversion unit which converts the decoded images of the second video data into third video data having the same resolution as the first video data, through interpolation using the additional information.
