Abstract: A moving picture encoding apparatus encodes a moving picture having an interlaced structure, and includes: a storage which stores fields as reference pictures; and an encoder which encodes a current field as a B-picture, using a first reference picture list which includes only one field in a same parity as the current field, and a second reference picture list which includes only one field in an opposite parity to the current field.

Abstract: A video coding apparatus is a video coding apparatus which codes a coding target video based on a coding standard, and includes: a dividing unit which divides an image included in the coding target video into a plurality of control blocks; and a prediction image generating unit which divides each of the control blocks into a plurality of prediction blocks, and generates, for each of the prediction blocks, a prediction image using one of inter prediction and intra prediction, wherein the coding standard allows each of the control blocks to be divided into the prediction blocks such that the prediction blocks have different sizes, and the prediction image generating unit divides each of the control blocks into the prediction blocks such that the prediction blocks all have an identical size, rather than dividing each of the control blocks into the prediction blocks such that the prediction blocks have different sizes.
