Abstract: A method for updating contents of a Digital Media Server (DMS) in a digital living network alliance system (DLNA) is disclosed. An update process is performed through a periodic update event in a Digital Media Player (DMP) that receives all content information of the DMS. Upon determining that information loss has occurred in the update process, the DMP sends to the DMS a request for information about a list of items possessed by the DMS. The DMP receives the requested information about the list of items and compares the received information about the list of items with information about pre-stored items to obtain a comparison result. When a difference occurs as the comparison result, all information about contents of the DMS is obtained through a browse action. When the difference does not occur as the comparison result, the update process is continuously performed.

Abstract: A system and method for data transmission in a DLNA network environment are disclosed. The data transmission system includes a content creation unit creating at least one content, a content correlation check unit checking a created content to classify the created content by category and a conversion content creation unit extracting header information and body information of the classified content and converting the extracted information into preset type information.

Abstract: The present invention relates to a method, apparatus, and system for data transmission based on a DLNA (Digital Living Network Alliance) network that classifies contents files which are stored in a DMS according to a support of the DLNA network to make a contents list. Support is provided to convert a file attribute of a selected file into a file attribute which can be applied to the DLNA network to generate, in case a user selects a non-supported file which is not applied to the DLNA network. The invention outputs the selected file to a display unit, captures the outputted image to convert into a file which can be applied to the DLNA network.

Abstract: A method for providing a multimedia messaging service according to the present invention includes the steps of: collecting multimedia contents accessible through a network in response to a request for preparing a multimedia message, generating the multimedia message including multimedia file access information by selecting a multimedia file from the collected multimedia contents, converting the multimedia message to a web page, transmitting the web page as an Internet mail, extracting the multimedia file access information from the web page included in the mail after receiving the mail, accessing a multimedia file by using the multimedia file access information and executing the multimedia file.

Abstract: A method for sharing a file between a control point and a media server in a DLNA system, and a system thereof are provided, in which the control point captures a photo, determines a similarity between a facial image included in the captured photo and a facial image file corresponding to at least one media server, compares the similarity with a pre-stored value, and if the similarity is greater than or equal to the pre-stored value, transmits a Uniform Resource Identifier (URI) representing a position at which the photo is stored to the media server, and the media server accesses the URI received from the control point and receives the photo using the URI.

Abstract: A method for sharing content using a Digital Living Network Alliance (DLNA) network is disclosed. The method includes the steps of creating a DLNA VPN (Virtual Private Network) between an inside-home DLNA network and at least one outside-home DLNA device, and delivering content from an inside-home DLNA device connected to the inside-home DLNA network to an outside-home DLNA device contained in the DLNA VPN in response to a request for content from the outside-home DLNA device. The method further allows continuous sharing of content, even if IP addresses of devices connected to the DLNA VPN are changed, by managing dynamic IP addresses of the devices connected to the DLNA VPN using an external network management server. Thus, the method allows outside-home DLNA devices to freely share content using a DLNA network. The method also allows various contents to be processed on a mobile terminal regardless of a storage space and processing capability of the mobile terminal.
