摘要

An information recording medium, an information recording method, an information reproducing method, an information recording apparatus, and an information reproducing apparatus are provided to detect whether a data recording unit includes reference picture or not by forming a management area for recording management information. An information recording medium comprises a data area(112), and a management area. The data area separately records data of a digital stream signal as plural data objects, each of which is separately recorded as one or more data units. The management area records predetermined management information used to manage recorded data in the data area. The management information has specific information indicating whether or not the data object includes a data unit which does not include any reference picture or I-picture in MPEG format.
