20080250504 | DIGITAL RIGHTS MANAGEMENT METHOD AND APPARATUS - A digital rights management (DRM) method and apparatus are provided. The DRM method includes transmitting a rights object request message; receiving a rights object response message based on a Universal Plug and Play (UPnP) contents directory service; and acquiring a rights object using the rights object response message. Another DRM method includes receiving a rights object request message; and transmitting a rights object response message based on a Universal Plug and Play (UPnP) contents directory service. The DRM apparatus includes a transmitting unit which transmits a rights object request message to a media server of a DRM domain; a receiving unit which receives a rights object response message based on a Universal Plug and Play (UPnP) contents directory service from the media server; and a playback unit which plays back a contents object on a basis of a rights object acquired using the rights object response message. | 10-09-2008 |
20080301289 | METHOD AND APPARATUS FOR SEARCHING FOR UPNP DEVICE - Provided is a method of searching for a Universal Plug and Play (UPnP) device in a UPnP network. Accordingly, a control point inserts attribute information on a device designated by a user in addition to information on a device type, a service type, or the like into a search message that is multicasted to search for a UPnP message, and a UPnP device which receives the search message determines whether or not the received attribute information corresponds to an attribute of the UPnP device with reference to a device description and a service description, and transmits a response message according to a result of the determining. Therefore, network traffic that occurs in an operation of searching for a UPnP device can be reduced, and a user can easily and rapidly search for a desired UPnP device. | 12-04-2008 |
20080307092 | METHOD AND APPARATUS FOR DETERMINING WHETHER CONTENT IS USABLE - Provided is a method of determining whether content provided from a first device is available to a second device in a network including the first and second devices. In the method, content domain information indicating a domain in which use of content provided from a first device is allowed is obtained from the first device, device domain information indicating a domain to which the second device belongs is obtained from the second device, the content domain information and the device domain information are compared to determine whether they are identical to each other, whether the content is available to the second device is determined based on the result of comparing. | 12-11-2008 |
20080310620 | METHOD, APPARATUS AND SYSTEM FOR MANAGING A/V PROFILES - A method, apparatus and system for managing A/V (Audio/Video) profiles are provided, which is related to a technology that supports different profiles in a domain. The method of managing A/V profiles includes requesting a license component and an encrypted content component, and creating a DRM license and encrypted content by gathering elements that correspond to an A/V profile of a specified device from the license component and the encrypted content component. | 12-18-2008 |
20090019058 | METHOD AND APPARATUS FOR RELAYING COMMUNICATION BETWEEN UNIVERSAL PLUG AND PLAY DEVICE AND REMOTE USER INTERFACE CLIENT - Provided is are method of relaying communication between a remote user interface (RUI) client and a universal plug and play (UPnP) device in a home network. The method includes: searching for a UPnP action mapped to an RUI element corresponding to an RUI control message received from an RUI client,; generating a simple object access protocol (SOAP) message for calling a found UPnP action; and transmitting the SOAP message to the UPnP device. | 01-15-2009 |
20090025085 | METHOD AND SYSTEM FOR DOWNLOADING DRM CONTENT - A method and system for downloading DRM contnt are provided. The method includes a first device supporting DRM technology and acquiring content information from a download descriptor downloaded from a content provider system, the first device transmitting the acquired content information to a second device not supporting DRM technology, and the second device downloading the DRM content from the content provider system using the downloaded content information. | 01-22-2009 |
20090064344 | METHOD AND APPARATUS FOR MANAGING DIGITAL RIGHTS MANAGEMENT RIGHTS OBJECTS - Provided are a method and apparatus for managing digital rights management (DRM) rights objects, and more particularly, to a method and apparatus for downloading and managing DRM rights objects by accessing a device, which does not support DRM technology, using a universal plug and play (UPnP) network. The method includes requesting a media server, which has downloaded specified content, to provide meta information of the content; determining whether to download a rights object for the content based on the meta information of the content; requesting an approval for the download of the rights object if it is determined to download the rights object; and providing the downloaded rights object to the media server. | 03-05-2009 |
20090235285 | METHOD AND APPARATUS FOR GENERATING MASHUP GRAPH, AND METHOD AND APPARATUS FOR RECOMMENDING MASHUP SERVICE - Provided are a method and apparatus for generating a mashup graph. The method includes receiving a set of services and collecting application programmable interfaces (APIs) of the services, and generating a mashup graph by using the collected APIs according to information regarding connections between the APIs and weights between the APIs. Thus, a mashup graph having a simple form in which a user's preference can be reflected can be generated, instead of a complicated connection matrix. | 09-17-2009 |
20110093525 | SYSTEM AND METHOD FOR PROFILING REMOTE USER INTERFACE - Provided are a network system and method for profiling a remote user interface (RUI), and more particularly, a network system and method for performing optimal RUI profile matching between an RUI client and an RUI server in order for optimal service adaptation for various contents based on composite capabilities/preference profiles (CC/PP). | 04-21-2011 |
20110138016 | DYNAMIC LOCAL FUNCTION BINDING APPARATUS AND METHOD - A dynamic local function binding apparatus and method are provided. In an application virtualization environment, a terminal may register local services associated with local functions of the terminal, and a remote server may call the serviced local functions to be used while the server is executing an application for the terminal.
