    摘要： The transmission format A license conversion unit (430) of the terminal device (120) converts the transmission format license (710), which is obtained from the license relay server (110), described in a transmission format into a processing format license (510) to be specified by the conversion format specification information (711) and detects modifications on the license whose format has already been converted by performing a signature verification on the after-conversion processing format license (510) using a processing format signature (712).

    摘要： To reduce a frequency of recording communication management information for communication disconnection countermeasure. A digital content distribution system includes a license server (101) that issues a license, and a user terminal (103) that controls use of content based on the issued license. The license server (101) judges, according to the license to be issued, whether or not the communication management information for the communication disconnection countermeasure needs to be recorded, and notifies the user terminal of a result of the judgment. This enables the user terminal (103) to reduce the frequency of recording the communication management information.

    摘要： A broadcast station that is a transmission device assigns an ID and a license transformation period to a license to be generated, and transmits to a terminal apparatus 102, in order to provide a digital right management system which can provide a protection for the rights of a provider while preventing an unauthorized obtainment of a license to be transmitted through a digital broadcast. The terminal apparatus 102 records a license import log including the license ID and license transformation period assigned to the license. Further, the terminal apparatus 102 controls a license obtainment in the case where the same license has been obtained by the time of obtaining the license. Furthermore, the license received by the terminal apparatus 102 is kept at least until the license transformation period expires.

    摘要： Provided is a content distribution system and the like that enables division at an appropriate position when dividing a content to record the content on a recording medium. A content distribution system (100) includes: a content distribution apparatus (200) that distributes a content; and a terminal apparatus (300) that records the content. The content distribution apparatus (200) includes: a storage unit (201) that stores division information indicating a division position at which the content is divided; and a distribution unit (204) that reads the division information from the storage unit (201) and distributes the division information to the terminal apparatus (300). The terminal apparatus (300) includes: a receiving unit (302) that receives the division information from the content distribution apparatus (200); and a recording unit (304) that obtains the content divided at the division position indicated by the division information and records divisional contents on plural recording medium (304).
