Abstract

A moving picture decoding method of an embodiment according to the present invention is a moving picture decoding method for decoding encoded data of an interlaced scanned picture including Top field and Bottom field, and the method includes a stereo information acquisition step for acquiring stereo information indicating whether Top field and Bottom field are two pictures forming a stereo picture from the encoded data, a decoding step for decoding two fields corresponding to each other from the encoded data and generating two decoded fields, and an output step for outputting the two decoded fields. In the output step, the stereo information is referred to and the two decoded fields are outputted simultaneously.
