摘要： A configuration is provided wherein usage restrictions of an application are determined in accordance with timestamps. A certificate revocation list (CRL) in which the revocation information of a content owner who is a providing entity of an application program recorded in a disc is recorded is referred to verify whether or not a content owner identifier recorded in an application certificate is included in the CRL, and in the case that the content owner identifier is included in the CRL, comparison between a timestamp stored in a content certificate and a CRL timestamp is executed, and in the case that the content certificate timestamp has date data equal to or later than the CRL timestamp, utilization processing of the application program is prohibited or restricted. According to the present configuration, a configuration is realized wherein an unrevoked application is not subjected to utilization restriction, and only a revoked application is subjected to utilization restriction.

摘要： An apparatus and method configured to identify the type of a content to be copied and perform a copying process in a sequence according to the result of identification is provided. In an information processing apparatus configured to perform the copying process for copying recorded data in an information recording medium to other media or the like, the type of the data recorded in the recording medium of a copy source is identified. More specifically, whether the type of the content to be copied is either a reproduction-pass-specific content which sets a reproduction pass corresponding to the information processing apparatus and causes the information processing apparatus to execute the reproduction according to the reproduction pass, or a content-code-applied content which verifies the reproduction sequence to be executed in the reproducing apparatus and verifies whether the reproduction process is executed according to the correct reproduction sequence is discriminated, and an optimal sequence is applied on the basis of the result of discrimination, whereby the copying process is executed. In this configuration, a reliable copying process on the basis of the optimal process according to various data types is realized.

摘要： An information processing system includes a medium storing contents for reproduction, and a reproducing device to reproduce the contents. The reproducing device obtains a device certificate and transmits the device certificate to the medium. The device certificate includes the reproducing device's type information, and the medium encodes a media ID for identifying the medium according to an encoding algorithm selected according to the reproducing device's type information. The encoded media ID is transmitted to the reproducing device, which decodes the encoded media ID according to a decoding algorithm corresponding to the device type of the reproducing device, and decrypts and reproduces data to which the obtained media ID is applied.

摘要： Executes a re-encoding after decoding data of a connection section A of a first MPEG picture data. This re-encoding is executed based on a control such that a transition of a VBV buffer occupation value starts from a VBV buffer occupation value at a position a and ends with a VBV buffer occupation value at a position d. Up to the position a of the first MPEG picture data, the first MPEG picture data is reproduced. Next, re-encoded MPEG picture data of the connection section A is reproduced. Thereafter, the data is connected to the position d of a second MPEG picture data, and the second MPEG picture data of the position d and after is reproduced.
