A first root certificate transform value is calculated by applying a first transform function to data constituting a first root certificate recorded in the first information recording medium and a second root certificate transform value is calculated by applying a second transform function to data constituting a second root certificate recorded in the second information recording medium. Transform values based on first and second root certificates are compared. A process under execution is continued when the first and second root certificate transform values match. However, the process under execution is stooped or a warning is output when the first and second root certificate transform values do not match.

Abstract: It is possible to accurately and securely execute conversion from an MPEG-2TS format to an MP4 format. A data converting unit that executes format conversion from an MPEG-2TS format to an MP4 format sorts out TS packets storing video data from MPEG-2TS format data, selects a TS packet having a start code (SC) at the top of a payload on the basis of header information of the sorted out TS packets, and extracts payload configuration data other than the start code (SC) and sets the payload configuration data as configuration data of MP4 format data. The data converting unit determines, on the basis of, for example, a value of a transport priority set in a header of the TS packet, whether or not the TS packet is a TS packet in which a start code (SC) is set in a top region of a payload.

Abstract: A situation where some data is missing is to be prevented in a process of recording data on a second medium in a different format from the data recording format of a first medium. An information processing device that reads the data recorded on the first medium, and performs a process of recording data on the second medium receives copy permission information from a management server, and acquires, from a data providing server, additional data that cannot be acquired directly from the first medium. The information processing device reads a copy control management file recorded on the first medium, and accesses and acquires the additional data by using access information recorded in the copy control management file. The information processing device then uses data containing the acquired additional data as the data to be recorded on the second medium.
