20100023980 | Information Processing Apparatus, Terminal Apparatus, and Program - An information processing apparatus includes a content purchase history storage unit in which a content purchase history for each user is stored, a metadata storage unit in which metadata of a plurality of contents is stored, and a metadata retrieval unit to retrieve, upon reception of a metadata retrieval request that is sent from a terminal apparatus of the user via a network and includes information for identifying a user and a retrieval condition, metadata of a content that meets the retrieval condition from the metadata storage unit, judge whether the content retrieved has already been purchased based on the content purchase history of the user that is stored in the content purchase history storage unit, and send a retrieval result of the metadata of the content that includes a judgment result to the terminal apparatus via the network as a metadata retrieval response. | 01-28-2010 |
20100293488 | EXTENDED ELEMENTS AND MECHANISMS FOR DISPLAYING A RICH GRAPHICAL USER INTERFACE IN PANEL SUBUNIT - Methods for realizing advanced graphical user interface (GUI) in panel subunit. The present invention provides, in one embodiment, a button GUI element descriptor that defines a bitmap to be displayed when a button is out of focus and another bitmap to be displayed when the button is in focus. In another embodiment, the present invention provides a table GUI element descriptor that defines a table-like on screen display to be displayed on the controller device. Another embodiment of the present invention provides a panel GUI element descriptor that includes a focused identifier attribute indicating a pre-determined element of the on-screen display as default focus. In this way, the target device would be able to control the default focus of the controller device when displaying an on-screen display. In yet another embodiment, the present invention provides a text GUI element descriptor that includes a font style attribute that dictates whether the text GUI element should be displayed as bold, underlined and/or reversed. By using these extended elements in panel subunit, more complicated and advanced GUI, such as an electronic programming guide (EPG) can be achieved. | 11-18-2010 |
20110010546 | INFORMATION PROCESSING APPARATUS AND METHOD, RECORDING MEDIUM AND PROGRAM - The present invention relates to an information processing apparatus allowing proper communication with a communication partner in accordance with a communication time of the communication partner. | 01-13-2011 |
20110072268 | SERVER APPARATUS, LICENSE DISTRIBUTION METHOD, AND CONTENT RECEPTION APPARATUS - [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. | 03-24-2011 |
20120096260 | CONTENT TRANSMISSION DEVICE, CONTENT TRANSMISSION METHOD, AND COMPUTER PROGRAM USED THEREWITH - A content transmission device for transmitting content, whose copying is controlled, includes an authentication section for performing an authentication procedure between the content transmission device and a content receiving device, a first copy-control-information processing section for processing first copy control information describing copy control information concerning the content, a second copy-control-information processing section for processing second copy control information including content information different from the first copy control information, and a content transmission section for generating and transmitting, to the content receiving device, a packet including a header including the first copy control information and the second copy control information, and a payload obtained by encrypting the content with a predetermined content key. | 04-19-2012 |
20120110613 | SYSTEM, APPARATUS, METHOD AND COMPUTER PROGRAM FOR TRANSFERRING CONTENT - Apparatus and methods are provided for moving electronic content between devices. In one implementation, an content-transmitting apparatus may include a transmitting unit configured to transmit content to a content-receiving apparatus. The content-transmitting apparatus may also include a determination unit configured to determine, in response to the transmission, whether first key information associated with the content-receiving apparatus corresponds to second key information associated with the content-transmitting apparatus. A receiving unit may be configured to receive a confirmation message from the content-receiving apparatus, and a confirmation unit may be configured to confirm whether the content is usable at the content-receiving apparatus, based on at least the confirmation message. | 05-03-2012 |
20120167172 | INFORMATION PROCESSING APPARATUS AND METHOD, RECORDING MEDIUM AND PROGRAM - The present invention relates to an information processing apparatus allowing proper communication with a communication partner in accordance with a communication time of the communication partner. | 06-28-2012 |
20120257744 | ENCIPHERING APPARATUS AND METHOD, DECIPHERING APPARATUS AND METHOD AS WELL AS INFORMATION PROCESSING APPARATUS AND METHOD - The invention provides an enciphering apparatus and method, a deciphering apparatus and method and an information processing apparatus and method by which illegal copying can be prevented with certainty. Data enciphered by a 1394 interface of a DVD player is transmitted to a personal computer and a magneto-optical disk apparatus through a 1394 bus. In the magneto-optical disk apparatus with which a change to a function is open to a user, the received data is deciphered by a 1394 interface. In contrast, in the personal computer with which a change to a function is open to a user, the enciphered data is deciphered using a time variable key by a 1394 interface, and a result of the decipherment is further deciphered using a session key by an application section. | 10-11-2012 |
20130236009 | ENCIPHERING APPARATUS AND METHOD, DECIPHERING APPARATUS AND METHOD AS WELL AS INFORMATION PROCESSING APPARATUS AND METHOD - The invention provides an enciphering apparatus and method, a deciphering apparatus and method and an information processing apparatus and method by which illegal copying can be prevented with certainty.

20140208113 | COMMUNICATION APPARATUS, COMMUNICATION METHOD, COMMUNICATION SYSTEM, AND COMPUTER PROGRAM - A measurement to obtain an RTT to a receiving apparatus is performed by a relay apparatus that is disposed between a WAN and a home network and connects these two networks. That an RTT value is equal to or less than the threshold value is set as a content distribution condition from a transmitting apparatus, so that the same use environment as a system using current DLNA and DTCP-IP can be realized for content use in the home network. Thereby, unjust distribution of content is prevented while an authentication and key exchange procedure performed via an external network is allowed. | 07-24-2014 |
