A coding apparatus includes a window information acquiring unit acquiring window information indicating an arrangement of windows on a screen that includes a plurality of windows, an identifying unit identifying macroblocks that include a border between overlapping windows from the window information and macroblock information indicating an arrangement of macroblocks into which the screen is partitioned, a classifying unit partitioning the identified macroblocks into sub-blocks so as to conform to the border and classifying the sub-blocks into which the macroblocks are partitioned into groups, and a coding unit coding the sub-blocks classified into the groups by applying the result of the motion vector prediction to the other sub-blocks classified in the same group.
