Claim 0:
1. A non-transitory computer readable medium storing instructions to be executed by a computer to perform a decoding process, the decoding process comprising:
acquiring an encoded signal and syntax information from a bitstream stored on the non-transitory computer readable medium, the bitstream being generated by encoding video in units of pictures based on a predetermined encoding standard;
acquiring video format information indicating whether the video is encoded with a video format among an interlace format of the predetermined encoding standard or a progressive format of the predetermined encoding standard, from a header of a sequence which is a unit of the video;
(i) setting each of all frames or all fields which are included in the video, as a picture included in the video, regardless of whether the video format is the interlace format of the predetermined encoding standard or the progressive format of the predetermined encoding standard, and (ii) setting a Picture Order Count (POC) indicating display order to each of the pictures included in the video one by one, the POC being different each other;
decoding a picture to be decoded, from among the pictures included in the video, with reference to a picture previously decoded before decoding the picture to be decoded, the picture to be decoded being a field or a frame; and
outputting the picture to be decoded, wherein
in the decoding, picture data of the picture to be decoded is always decoded with a syntax structure, which is a syntax structure for decoding common format of the predetermined encoding standard regardless of whether the video format is the interlace format of the predetermined encoding standard or the progressive format of the predetermined encoding standard.
