摘要： When a control unit of a content receiver causes to write out content to an exchangeable medium, causes to also write out a viewing license of the content to the exchangeable medium, and further causes an invalidating/validating unit to invalidate a viewing license of related content belonging to a same predetermined content group as the content if a viewing time limit of the content is not determined. When a content reproducer reproduces the content recorded in the exchangeable medium, determines the viewing time limit of the content and records it to the exchangeable medium. When the exchangeable medium which is reproduced by the content reproducer is installed, the control unit causes to set a viewing time limit of the related content to the same time limit as the viewing time limit of the content on the exchangeable medium and causes to validate the viewing license of the related content.
