Information recording/reproducing system decodes an MPEG data stream constituted of one-grouped pictures of I 2 , B 0 , B 1 , P 5 , B 3 , B 4 , P 8 , B 6 , B 7 , P 11 , B 9 , B 10 , P 14 , B 12 , and B 13 in turn on B picture, P picture and I picture to become the MPEG data stream constituted of one-grouped pictures of I 2 , P 5 , B 3 , B 4 , P 8 , B 6 , B 7 , P 11 , B 9 , B 10 , P 14 , B 12 , B 13 , I 2 , B 0 , and B 1 in turn on the B picture, the P picture and the I picture. The system produces a reproduced image that is constituted of one-grouped pictures of I 2 , B 3 , B 4 , P 5 , B 6 , B 7 , P 8 , B 9 , B 10 , P 11 , B 12 , B 13 , P 14 , B 0 , and B 1 in turn on the B picture, the P picture and the I picture. The reproduced image can prevent any necessary picture from being lacked and get any smoothly reverse reproduction images.
