Access point pictures designated as randomly accessible positions are I pictures or P pictures. Information indicating the decoding sequence (I 1 , P 1 , B 1 , B 2 , B 3 , B 4 , P 2 , . . . ) of pictures functioning as access points and attribute information (picture-type) indicating whether a picture functions as an access point or is necessary for decoding of the access point following a given access point are recorded on the video information recording medium. Random access is possible even if the GOP interval is lengthened. |
