The decoding method includes: decoding a first frame which is a P frame that is to be displayed last among a plurality of P frames that are to be displayed before an IDR-I frame is displayed; decoding the IDR-I frame; decoding a second frame which is a P frame that is to be displayed first among a plurality of P frames that are to be displayed after the IDR-I frame is displayed; and maintaining a reference frame stored in a buffer, for decoding the first frame until the second frame is decoded. Therefore, by allowing frames near an IDR-I frame to access reference frames stored in a buffer, natural picture conversion is possible, and accordingly smooth picture conversion without flickering is possible.
