摘要： [Object] To realize processing for switching a reproduction state from broadcast data to network data and resuming the reproduction of the original broadcast data.[Solving Means] A browser (241) acquires, via a network, an XML-AIT having a content equivalent to a broadcast AIT defining a life cycle of a broadcast application while a VoD content is reproduced after being switched from the broadcast application. The browser (241) manages the broadcast application based on the XML-AIT and resumes the reception of the broadcast application after the reproduction of the VoD content is ended. With this structure, processing of separating two transport streams at the same time becomes unnecessary, and one demultiplexer (23) only needs to be provided.

摘要： There are provided a content distribution system and a license management method for performing, in a collective manner, license management of a plurality of resources contained in contents. Each piece of content contains one upper-level resource (which is first referred to within the content), at least one lower-level resource (which can be referred directly or indirectly from the upper-level resource), one startup document and a license-corresponding document (which is an information file for performing, in a collective manner, license management of the resources contained in the content). The startup document contains at least upper-level resource reference destination information and at least one piece of license information for identifying view licenses required for viewing the resources contained in the content. In each resource, if link information for accessing other content is described, information for accessing the startup document of the other content is described.
