要約
(EN)
To download a subcontent related to a content from a network even when a recording medium on which the content is recorded is not inserted into an electronic device. [MEANS FOR SOLVING PROBLEMS] A resident application of a recording/reproducing apparatus (100) reads metadata recorded on a BD-ROM while the BD-ROM is inserted into the recording/reproducing apparatus (100) and stores the metadata into a disk library DB (34). Then, when the BD-ROM is not inserted into the recording/reproducing apparatus (100), based on the URL of a content server (22) included in the metadata stored in the disk library DB (34), the resident application downloads a new trailer from the content server (22) and stores the new trailer into a local storage (38). This makes it possible for the resident application to reproduce, through a disk library (30), the new trailer stored in the local storage (38) even when the BD-ROM is not inserted.

本发明涉及一种电子设备、再现方法和程序。目的是为了即使当记录有内容的记录介质没有插入到电子设备时也下载与内容相关的子内容。解决方式:当BD-ROM插入到记录/再现设备100时,记录/再现设备100中的驻留应用程序读取存储在BD-ROM中的元数据并把元数据存储在盘库DB 34中。当BD-ROM没有插入到记录/再现设备100时,驻留应用程序基于盘库DB 34中存储的元数据所包括的内容服务器22的URL,从内容服务器22下载最新的预告片,并随后把最新预告片存储在本地存储器8中。因此,即使当没有插入BD-ROM时,驻留应用程序也能够经盘库30再现存储在本地存储器8中的最新预告片。
