PROBLEM TO BE SOLVED: To provide a decoding method and an encoding method which are capable of reducing output delay for pictures.SOLUTION: Output delay for pictures is reduced by determining S36 after a current picture has been decoded S35 and stored in a decoded picture buffer DPB, the number of pictures in the DPB that are marked as needed for output. This number is compared S37 against a value derived from at least one syntax element present in a bitstream representing pictures of a video sequence. If this number is greater than the value, a picture, which is the first picture in output order, of the pictures in the DPB that are marked as needed for output is output S38 and marked S39 as not needed for output. |
