Such network profile information stores the network type and network status information corresponding to the user ID or the identification number of the terminal used by the user, and through which network the terminal currently used by the user is connected. You can show what is being done.

  Next, a terminal registration and release procedure required for continuously providing content according to an embodiment of the present invention will be described in detail with reference to FIG.

  FIG. 3 is a flowchart showing a terminal registration and release procedure according to the embodiment of the present invention.

  As shown in FIG. 3, the browser operates in one terminal among the plurality of terminals 100 (S101). Then, one terminal transmits a processing mode message for requesting a mode set to the content conversion system 300 so that the continuously converted content can be received from the content conversion system 300, and the content conversion system 300 is continuously transmitted. The operation request processing mode is set (S102).

  The content conversion system 300 registers the terminal that has requested the operation, and stores and manages the profile information of the user related to the registered terminal and the profile information of the terminal in the profile device 400 (S103).

  The content conversion system 300 starts an operation of converting the content corresponding to the registered status conversion information of the terminal in accordance with the browser environment (S104). Further, the content conversion system 300 stores the status information of the converted content.

  While performing the conversion processing operation, the content conversion system 300 determines whether there is an operation processing release request from the registered terminal (S105).

  As a result of the determination, if an operation process release request is received, the content conversion system 300 controls the profile device 400 to delete information on the terminal that requested the operation process release (S106). Here, the information of the terminal to be deleted includes the status information of the converted content of the terminal requested to be released, the profile information of the terminal, that is, hardware-related information for each terminal, the network type and network status information of the terminal.

  On the other hand, if there is no operation processing release request, the content conversion system 300 continuously performs an operation of converting content corresponding to the status conversion information of the terminal (S107).

  Next, a content conversion process in an environment where the status of the terminal is converted will be described in detail with reference to FIG.

  FIG. 4 is a flowchart showing a content conversion procedure according to the embodiment of the present invention.

  Here, in the content conversion system 300 according to the embodiment of the present invention, the content conversion process will be described using the first terminal 110 and the second terminal 120 among the plurality of terminals 100 as an example.

  First, as shown in FIG. 4, the first terminal 110 transmits a first registration request message to the situation conversion automatic search unit 310 to request registration in order to continuously receive content (S201). In response to such a registration request, user profile information regarding the first terminal 110 and terminal profile information are stored in the profile device 400 and managed. Next, the content conversion system 300 converts the content according to the profile information of the first terminal 110, and continuously provides the converted content to the first terminal 110.

  While providing content to the first terminal 110, the situation conversion automatic search unit 310 continuously searches for the situation conversion of the first terminal 110 and the second terminal 120 without interruption (S202).

  When the user changes the terminal from the first terminal 110 to the second terminal 120, the second terminal 120 transmits a second registration request message to the situation conversion automatic search unit 310 to make a registration request (S203). In response to such a registration request, user profile information and terminal profile information related to the second terminal 120 are stored and managed in the profile device 400. In addition, the second terminal 120 transmits terminal registration information included in the second registration request message to the content conversion system 300 via HTTP (hypertext transfer protocol). On the other hand, the first terminal 110 releases the connection with the content conversion system 300 in order to stop providing the converted content provided continuously from the content conversion system 300.

  The situation conversion automatic search unit 310 performs the situation conversion corresponding to the terminal change to the other terminal, that is, the second terminal 120, which is not the first terminal 110, and the profile information of the first terminal 110 already stored and the second The comparison is made with the profile information of the terminal 120 (S204). If the profile information of the first terminal 110 and the profile information of the second terminal 120 do not match as a result of comparing the profile information, the situation conversion automatic search unit 310 determines that the user has changed the terminal from the first terminal 110 to the second terminal 120. Is determined to have been changed. The situation conversion according to the embodiment of the present invention corresponds to a user terminal change or a terminal network change.

  When the user changes the terminal from the first terminal 110 to the second terminal 120, the situation conversion automatic search unit 310 moves service provision to the second terminal 120.

  Next, the situation conversion automatic search unit 310 transmits a profile information request message requesting profile information of the second terminal 120 corresponding to the situation conversion to the profile management unit 320 (S205). The situation conversion automatic search unit 310 transmits the model information of the second terminal 120 included in the profile information request message, and requests detailed profile information of the second terminal 120 from the profile management unit 320. Detailed profile information of the second terminal 120 is, for example, hardware specification information such as screen size and audio / video format information.

  The profile management unit 320 transmits a profile information response message including profile information corresponding to the profile information request message to the situation conversion automatic search unit 310 (S206).

  The situation conversion automatic search unit 310 uses the received profile information to generate a content conversion processing request message for content conversion processing corresponding to the terminal status conversion, and transmits this message to the content conversion processing unit 330 (S207). ). At this time, the content conversion processing request message includes terminal status conversion information. The terminal status conversion information is transmitted via HTTP.

  The content conversion processing unit 330 converts the content so as to correspond to the received content conversion processing request message. For example, the content conversion processing unit 330 converts the content by screen reconstruction corresponding to the difference in screen size between the first terminal 110 and the second terminal 120. Also, the content is converted by a conversion algorithm corresponding to the audio / video format difference.

  The content conversion processing unit 330 transmits the converted content to the situation conversion automatic search unit 310 (S208). Further, the situation conversion automatic search unit 310 transmits the content to the second terminal 120 (S209).

  Therefore, according to the embodiment of the present invention, even when a single user has a plurality of terminals and is connected to the system to receive a service, the content is converted according to the characteristics of each terminal and provided. Content can be received continuously.

  In FIG. 4, the case where the user changes the terminal from the first terminal 110 to the second terminal 120 has been described. However, in the content conversion system according to the embodiment of the present invention, one terminal moves between different types of networks. Also, converted content corresponding to the modified network is provided. In the content conversion system 300 according to the embodiment of the present invention, a case where a user changes a terminal network from a wireless LAN to a cellular network will be described as an example.

  In order to continuously receive content, one terminal transmits a registration request message to the situation conversion automatic search unit 310 via the wireless LAN to make a registration request. In response to such a registration request, user profile information related to the terminal, wireless LAN profile information, that is, a wireless LAN connection device related identification number is stored in the profile device 400 and managed. Next, the content conversion system 300 converts the content corresponding to the wireless LAN, and continuously provides the converted content to the terminal.

  While providing content to the terminal via the wireless LAN, the situation conversion automatic search unit 310 continuously searches for situation conversion corresponding to the network change of the terminal without interruption. When the user changes the terminal network from the wireless LAN to the cellular network, the terminal transmits a registration request message to the situation conversion automatic search unit 310 via the cellular network to make a registration request. In response to such a registration request, user profile information related to a terminal, cellular network profile information, that is, a cellular network connection device related identification number is stored in the profile device 400 and managed.

  The situation conversion automatic search unit 310 performs the situation conversion corresponding to the network change of the terminal to the cellular network, which is not the wireless LAN, and the already stored wireless LAN connection device related identification number and the cellular network connection device related identification number. Compare and judge. As a result of comparing the identification numbers, if they do not match, the situation conversion automatic search unit 310 moves the service provision through the cellular network. Then, the content conversion processing unit 330 converts and provides the content so as to correspond to the changed network.

  Therefore, the content conversion system according to the embodiment of the present invention searches for status conversion information according to the network change of the terminal even when the terminal moves between different types of networks, and obtains profile information according to the search result. The process of receiving and converting the content is the same as the process of searching for status conversion information according to the change of the terminal when the terminal is changed and receiving the profile information and converting the content according to the search result. .

  As described above, the content conversion system according to the embodiment of the present invention converts the content when the terminal moves between different types of networks or when the user changes the terminal that has received the converted content to another terminal. By automatically searching for a change in the status of the terminal on the system side and converting the content according to the result, it is possible to continuously support the content requested by the terminal whose status has been changed.
