Abstract

The present application relates to an information reproducing device and an information reproducing method. An information recording medium includes: encrypted content (502) purchased through a network; and purchase type information (148) indicating a purchase type of the content included in a management information area conforming to a digital versatile disc video recording standard.

Description

technical field [0001] The present invention relates to an information reproducing apparatus and an information reproducing method for reproducing data from an information recording medium (or an information storage medium) such as an optical disc that records content downloaded through a network. Background technique [0002] In a conventional content delivery system using a network, in a local device, usage right information indicating a license as a usage right corresponding to content is stored in a license storage device. When content is used, rights information is output from the license storage device to the content usage device. In addition, the output right information is sent to the content delivery server. In the content distribution server, a validity check is performed on the rights information. Only when the validity is successfully checked, the content corresponding to the rights information is sent from the distribution server to the content usage device. ...
