Abstract: A method for monitoring time so that the use of protected content can be controlled includes receiving a trusted time value from a trusted authority external to a client device. When the client is no longer in communication with the trusted authority, the previously-received trusted time value is updated by use of the client's operating system counter so that a calculated trusted time value is derived for content license evaluation purposes.

Abstract: [Object] To stabilize an operation of a license server by avoiding concentration of license acquisition requests from a large number of clients at a time right after a broadcast start time of a content. [Solving Means] A web server (21) of an IPTV server sets an acquisition request time of a main license within a time period from a broadcast start time to a predetermined set time at random in accordance with an acquisition request of a license for reproducing an encrypted content, the acquisition request being from an IPTV client terminal (10), and transmits, to the IPTV client terminal (10), information on the acquisition request time of the main license and a temporary license including a temporary content key that corresponds to a reproduction of the broadcast content from the broadcast start time to the predetermined set time. A license server (22) transmits the main license including a main content key that corresponds to a whole reproduction of the content in accordance with an acquisition request of the main license, which is executed in the IPTV client terminal (10) based on the information on the acquisition request time.

Abstract: An information processing device, method, recording medium, and program capable of preventing lack of information when importing or exporting a content. In step (S301), a CPU extracts an audio track contained in the content. In step (S302), the CPU converts the format of the extracted audio track into a format corresponding to a memory stick. In step (S304), the CPU generates a predetermined file from data excluding the audio track. In step (S306), the CPU adds reference information on the audio track to the file. In step (S307), the CPU controls write of the audio track whose format has been converted and the file into the memory stick. The present invention may be applied to a DRM system client.

Abstract: An information processing device and method, a program storing medium, and a program capable of distributing a use right for each small content without causing a large load on a client. A use right of a content holder server (6) is provided to a license server (4). The license server (4) divides the use right provided from the content holder server (6), for example, to a use right for only reproduction and a use right for reproduction and check out. A client (1) pays 10 yen to acquire use right for reproduction. The client (1) further pays 30 yen to acquire the use right for reproduction and check out. That is, the use right for only reproduction is upgraded to the use right containing reproduction and check out. The present invention can be applied to a server providing a content via a network.
