Abstract
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.
