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.
