Abstract: According to one embodiment, an information processor includes a management module that manages a plurality of register areas in a host controller for processing data protected by copyright. The register areas store confidential information for copyright protection. The management module includes a use state management module and a release module. The use state management module manages use state information on whether the register areas are used by existing process tasks. When all the register areas are occupied by the existing process tasks and a new process task requests for the use of a register area to perform a process based on the confidential information, the release module releases a register area occupied by one of the existing process tasks according to the use state information to assign the register area to the new process task.

Abstract: According to one embodiment, a contents list providing apparatus includes a list obtaining unit which obtains a contents list of contents stored in a contents server coupled to the contents list providing apparatus via a network. An updated list generating unit generates, based on the contents list obtained by the list obtaining unit, an updated contents list including an updated content. An updated list providing unit provides, to a communication terminal coupled to the network, the updated contents list generated by the updated list generating unit.

Abstract: According to one embodiment, an electronic apparatus includes a wireless communication device, an information acquisition module, a file management information generation module, and an access control module. The information acquisition module acquires, by wireless communication with an external device, metadata corresponding to content data which the external device can provide. The file management information generation module generates, based on the acquired metadata, file management information based on which a host apparatus recognizes the content data as a file stored in a storage medium in the electronic apparatus. The access control module is configured to, upon receiving a read request for a file corresponding to the content data, which is transmitted from the host apparatus, execute external device access processing of acquiring the content data from the external device using the wireless communication device, and output the acquired content data to the host apparatus.

Abstract: According to one embodiment, an electronic apparatus is detachably connected to a host apparatus. The electronic apparatus includes a file management information generation module. The file management information generation module generates file management information based on which a host apparatus recognizes each of content data items as a file stored in a storage medium, the file management information being indicative of a plurality of starting storage locations on the storage medium corresponding to starting data blocks of the content data items, and a plurality of shared storage locations on the storage medium, which are shared by the content data items and correspond to second and following data blocks of each of the content data items.

Abstract: According to one embodiment, a display apparatus includes a card slot configured to be insertable a memory card including a user data area in which one or more encrypted content keys encrypted with a user key and list information of content-specific information unique to each of content items corresponding to the respective encrypted content keys are stored, a close-proximity wireless transfer device configured to be able to transfer with an external device, an information acquisition module configured to acquire the content-specific information of content held by the external device with which the close-proximity wireless transfer device is executing close-proximity wireless transfer, a content-specific information detection module configured to detect the content-specific information corresponding with information indicating the acquired content, from the list information stored in the user data area, and a display processing module configured to display a list of content items corresponding to the detected

Abstract: A portable electronic device includes a transmitting circuit, an X-ray detector, and a controller. The transmitting circuit includes a power amplifier for amplifying radio waves. The detector is arranged to detect X-rays radiated from an installation arranged on a passageway to an area where radiation of electromagnetic waves is restricted. When X-rays with a certain intensity or more are detected by the detector, a controller recognizes that the device is about to enter the area, and reduce the gain of the power amplifier, so that the transmitting circuit is set to be unable to radiate radio waves.
