    Abstract: According to one embodiment, this invention allows to acquire attribute information of a stream object and to generate it as management information upon recording a digital stream when an MPEG-TS that uses H.264 as a moving picture encoding format is to be recorded. Information is acquired from a component descriptor, a PES packet header, or a sequence parameter set in a program map table included in the digital stream signal, and video attribute information of the object and/or attribute information of the data unit is determined. The object is recorded for each data unit, and management information that manages the recorded is recorded.

    Abstract: In an embodiment, a PATS counter synchronized with an SCR superposed on an MPEG-TS is used. When recording the MPEG-TS, a pair of the value of time stamp information (PTS/DTS) of a previously detected picture and the value of the PATS counter are stored (ST500-ST510). When detecting the next time stamp information, an increase in the time stamp information is compared with an increase in the PATS counter (ST512-ST526). If the significant difference is exhibited (YES in ST600), it is determined that an error is found in the time stamp information value, and a recording process is performed (ST530).

    Abstract: According to one embodiment, an access management system such as an AACS is used to protect highly confidential information recorded in a write-once medium. To first prepare a title key file for encryption by the AACS, title keys are prepared as many as the number of rules of a usage rule file. The plurality of title keys prepared in this manner are written in the title key file. The title keys written in this title key file are appropriately used to encrypt contents, and the encrypted contents are then recorded in the write-once medium.
