| Abstract | This invention provides a recording medium for recording various AV streams, which enables to perform a random access and is suitable for a DVD-RAM or the like, Also provided are an apparatus and a method for accessing the recording medium. The information recording medium (100) stores, as management information, object information for managing an object. The object information includes an access map (86c) for managing an MPEG transport stream for each block unit which is comprised of the integer-times number of ECC blocks. The access map (86c) has, in addition to predetermined access information for the block, a flag (811a) indicating whether the block includes an I-picture or not. |
