Abstract:
1. A moving picture reproducing device which decodes compressed moving picture into decoded image displayed on a display device, comprising: a plurality of decoding units each of which decodes the compressed moving picture in a resolution which is different from resolutions of the other decoding units; a display size obtaining unit which obtains a display size of image displayed on the display device; and a decoding unit selecting unit which selects a decoding unit to decode the compressed moving picture, from the plurality of decoding units according to the display size obtained by the display size obtaining unit, wherein the decoding unit selecting unit newly selects the decoding unit whenever the selected decoding unit decodes a predetermined amount of the compressed moving pictures, wherein the moving picture is compressed based on MPEG and the decoding unit selecting unit selects the decoding unit for each GOP (Group of Picture), and wherein the decoding unit selecting unit selects, at the beginning of decoding process of current GOP, a decoding unit used in the decoding process of the previous GOP, when a B picture in the current GOP includes information related to an I picture and a P picture of the previous GOP.
