Abstract:
1. A content receiver that receives a content, for which a viewing time limit is managed, from a content server, and that writes out the content to a non-transitory exchangeable medium, the content receiver comprising: a viewing license invalidating unit that invalidates a viewing license of the content; and a first control unit that (i) judges whether the viewing license is valid, (ii) judges whether the viewing time limit of the content is determined, (iii) writes out the content to the exchangeable medium, and (iv) reproduces the content, wherein when the first control unit judges that the viewing license is valid and the viewing time limit of the content is not determined, the first control unit (i) causes the viewing license invalidating unit to invalidate the viewing license before writing out the content to the exchangeable medium, and (ii) writes out information indicating that the viewing time limit of the content is not determined to the exchangeable medium, and wherein after the first control unit writes out the viewing time limit of the content to the exchangeable medium, the first control unit (i) transmits a viewing license request, which includes a request of determining the viewing time limit of the content, to a license server, (ii) receives a determined viewing time limit of the content and the viewing license from the license server, and (iii) reproduces the content.
