1. A non-transitory computer readable medium storing a bitstream to be executed by a computer to perform a decoding process, the bitstream being encoded by a method for encoding video in units of pictures based on a predetermined encoding standard to generate an encoded bitstream, the encoding method comprising:
determining video format information indicating which video format is used for encoding the video from among an interlace format of the predetermined encoding standard or a progressive format of the predetermined encoding standard,
(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, and
encoding a picture to be encoded, from among the pictures included in the video, with reference to a picture previously encoded before encoding the picture to be encoded, the picture to be encoded being a field or a frame, wherein
in the encoding, (i) picture data of the picture to be encoded is always encoded with a syntax structure, which is a syntax structure for encoding the progressive 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, (ii) the video format information indicating the video format is encoded in a header of a sequence which is a unit of the video, and (iii) the encoded bitstream is generated.
