Abstract: When license information is transferred between a server machine and a client machine, an identifier which is unique to a series of communication sequences is provided. The identifier is sent when a communication is performed between the two machines, as well as when the license information is updated. Therefore, when a message for transferring the license information is received by the use of the same identifier, a response message is returned without updating the license information.

Abstract: A thermal conductive mechanism for a battery pack made up of a stack of a plurality of sub-battery modules each of which includes a plurality of battery cells arrayed thereon. The sub-battery modules each has opposed major surfaces and are laid to overlap each other in a direction perpendicular to the major surfaces. The thermal conductive mechanism is equipped with plates provided one for each of the sub-battery modules. Each of the plates has a given number of the battery cells disposed thereon and also has heat transfer surfaces extending in a planar direction of the plate. The heat transfer surfaces are placed in one of direct and indirect contact with the given number of the battery cells to achieve transfer of heat therebetween, thereby equalizing the temperature in each of the battery cells and also minimizing a difference in temperature among the battery cells.

Abstract: An information processing device that attaches common accompanying data to a content group composed of contents. The information processing device acquires the contents, acquires one or more characteristics of each acquired content and searches among reference data items in order to acquire one or more reference data items that each include any of the one or more characteristics, each reference data item having attached thereto at least one attribute used for identifying the reference data item, the reference data items being data other than the contents. The information processing device then specifies, among the attributes attached to the acquired one or more reference data items, an attribute that also pertains to the contents, uses the specified attribute as an attribute for identifying each of the contents, and attaches the specified attribute to each of the contents.

Abstract: When a secure counter malfunction detection unit 212 deters a malfunction in a secure counter 211, a content playability judgment unit 206 performs a content playability judgment based on information managed by a malfunctioning-state playback processing management unit 214. The malfunctioning-state playback processing management unit 214 stores a malfunctioning-state playback condition composed of information such as a playback count and a playback time. The content playability judgment unit 206 judges that content is playable when the malfunctioning-state playback condition is met, and a content playback unit 210 splays the content.

Abstract: A video search device extracts a plurality of objects each contained in a different one of frames of a video, assigns a weight value to each of the extracted objects based on a time-series feature of the frame containing the object, and searches for an object similar to each of the extracted objects based on the extracted objects each having the weight value assigned thereto.

Abstract: When license information is transferred between a server machine and a client machine, an identifier which is unique to a series of communication sequences is provided. The identifier is sent when a communication is performed between the two machines, as well as when the license information is updated. Therefore, when a message for transferring the license information is received by the use of the same identifier, a response message is returned without updating the license information.

Abstract: A content distribution system distributes a content key and content use conditions for controlling a content use in a client apparatus to the client apparatus, via a communication channel, from either a multicast distribution server or a unicast distribution server. A content distribution management server determines by which distribution method to send the content key and content use conditions of each content according to an attribute of the content (a compression format, a compression ratio, a content holder, and the like). An encrypted content distribution server distributes only encrypted content whose content key and content use conditions are to be distributed by the unicast, and the multicast distribution server distributes encrypted content whose content key and content use conditions are superimposed by the multicast.

Abstract: A contents using device (or a terminal device) 300 is composed of: a license processing unit 305 which judges, on the basis of a usage rule of a license, whether or not the content is available; a content reproduction unit 304 which uses the content judged by the terminal device 300 to be available; a restriction unit (or a content reproduction unit 304) which restricts the license corresponding to the contents from being used by another source by reason that the license is currently in use, for a time period between a start and a normal end of the content usage by the content reproduction unit 304; an event detection unit 307 which detects a predetermined event that occurs between the start and the normal end of the content usage and that forcefully aborts the content usage; a restriction-relaxation necessity judgment unit (or a recovery/penalty judgment unit) 309 which judges whether or not the predetermined event is against an intention of a user; and a restriction relaxation unit (or a license recovery un

Abstract: A content usage device includes (i) a license management unit that holds license information and (ii) a content output unit that uses a content in compliance with license information and outputs the content in at least one manner of a sound, video and data. The license management unit, upon receiving a request of license information from the content output unit, requests a license management unit of another content usage device to transfer the license information and acquires the license information, and passes the acquired license information to the content output unit. The content output unit uses a content in compliance with the license information passed from the license management unit.

Abstract: A method is provided for judging use permission of information on one or more terminal apparatuses which use content provided by a content provider and metadata provided by a metadata provider and supplementing the content, the method comprising: metadata use permission judgment judging use permission of the metadata based on usage control information regarding use control of the metadata; and using the metadata in the case where in said metadata use permission judgment, the use of the metadata is permitted. Specifically, the usage control information includes the first signer identification information which identifies the range of the provider of the metadata that can be used. The metadata includes a signature of the metadata provider identified in the first signer identification information, and the second signer identification information identifying the signer of the signature.
