Abstract:
1. A content receiver that receives content with a viewing license accompanied by a viewing time limit managed from a content server and that writes out the content along with the viewing license of the content to an exchangeable medium, the content receiver comprising: a license invalidating/validating unit that invalidates and validates the viewing license; an exchangeable medium reading/writing unit that writes out the content along with the viewing license of the content to the exchangeable medium and that reads at least the viewing license written in the exchangeable medium; a viewing time limit setting unit that sets the viewing time limit; and a control unit, wherein when the control unit causes the exchangeable medium reading/writing unit to write out the content to the exchangeable medium before the content is reproduced, the control unit causes the exchangeable medium reading/writing unit to also write out the viewing license of the content to the exchangeable medium, and further causes the license invalidating/validating unit to invalidate the viewing license of related content belonging to a predetermined content group to which the content to be written out belongs if the viewing time limit of the content is not set, and when the exchangeable medium with the viewing license of the content being written thereto, which is accompanied by the viewing time limit that has been set by reproducing of the content written out to the exchangeable medium, is installed, the control unit causes the viewing time limit setting unit to set the viewing time limit, which is the same as the viewing time limit of the reproduced content, for the related content and causes the license invalidating/validating unit to validate the viewing license of the related content.
