Description

  The present invention relates to a data relay device used by connecting to a network such as the Internet, a data transmission system using the data relay device, a data transmission method using the system, and a program for executing the data transmission processing .

  In recent years, there is a content storage / sharing service as one of services using the Internet. This allows a server on the network to upload and store content (files) that you want to store, and when necessary, access it from the required location to download and use the stored content. It is a thing.

  FIG. 5 shows an example of this type of service. In this example, content such as video data stored in the computer device 1 installed at home is uploaded to the server 2 via the Internet (step Sa). When the content stored in the server 2 becomes necessary in the destination computer device 3, the computer device 3 is connected to the server 2 via the Internet, and the content is downloaded from the server 2 ( Step Sb). In this way, by storing the content in the server 2 in advance, it is possible for the destination computer device 3 to retrieve the stored content as long as an environment capable of connecting to the Internet is prepared. become.

  In this case, the stored content can be shared by a plurality of terminal devices. That is, for example, as shown in FIG. 6, in addition to the home computer device 1, a plurality of computer devices 3, 4, and 5 that can share content stored in the server 2 are prepared, and the content is uploaded to the server 2. After that (step Sa), the same content data can be downloaded (steps Sb, Sc, Sd) to each of the computer devices 3, 4, 5.

  Further, for example, as shown in FIG. 7, after an information device 6 such as a digital still camera is connected to the computer device 3, the content data obtained by the information device 6 is once transferred to the computer device 3, The computer apparatus 3 uploads to the server 2 (step Se), and the content data stored in the server 2 is downloaded to the home computer apparatus 1 (step Sf). By performing the processing as shown in FIG. 7, for example, by using a digital still camera as the information device 6, contents such as video data obtained by photographing outside can be transferred to a desired user. In this case, the computer device 3 connected to the information device 6 is used to prepare a communication environment that can be connected to the Internet, and access processing to the server 2 is performed.

A server for storing such contents is prepared by, for example, an Internet provider that provides Internet connection services. Non-Patent Document 1 describes a service example of a provider that provides such a service.

  In this way, if a device such as a computer device that can be connected to the Internet is prepared, a content transfer service such as video data can be received. However, when uploading or downloading content, the transfer is actually started. There has been a problem that the operation until this time is complicated. Further, the operation for transferring the content is completely different for each service provider, and it cannot be said that it is always easy for the user to use. The operation for transferring content is executed using, for example, a computer device connected to the Internet.

  FIG. 8 is a diagram illustrating a change example of the operation screen displayed on the display of the personal computer device when the content transfer service is used. First, a login screen is displayed in a state where it is connected to the address of the corresponding server (step ST11), and if there is a login operation on that screen, the display moves to a menu screen (step ST12). The login screen is displayed as shown in FIG. 10, for example, and is configured to input a user ID and a password. Further, the menu screen is displayed as shown in FIG. 11, for example, a display for selecting uploading to the server, downloading from the server, folder creation, etc., a list of prepared folder names and file names, and the like. Is supposed to do. In addition, a display for selecting logout is also performed. If logout is selected while the menu screen is displayed, the screen returns to the login screen display of step ST11.

  When upload is selected in the menu screen display, the process proceeds to display of the upload input screen (step ST13). The upload input screen is displayed as shown in FIG. 12, for example, and displays the name of the folder or file to be uploaded and the display for executing the upload. After selecting the folder or file to be uploaded, the display for executing the upload is clicked, so that the upload is executed and the screen moves to the upload status display screen (step ST14). The upload status display screen is displayed as shown in FIG. 13, for example, and the name of the file being transferred is displayed on the server side. When the upload state is completed, the display returns to the menu screen display in step ST12.

  When download is selected on the menu screen display, the display shifts to display of a download input screen (step ST15). The download input screen is displayed as shown in FIG. 14, for example, and displays the name of the folder to be downloaded and the display for executing the download. After selecting the folder or file to be downloaded, the display for executing the download is clicked, so that the download is executed, and the screen moves to the download status display screen (step ST16). The download status display screen is displayed as shown in FIG. 15, for example, and the name of the file being transferred from the server side is displayed. When this download state ends, the display returns to the menu screen display in step ST12.

  FIG. 9 shows the flow of processing between the server and the computer apparatus. FIG. 9 shows an example of uploading data (content) from a computer device to a server. First, there is a login screen request from the computer device to the server (step S11), and the login screen data as shown in FIG. 10 is transferred from the server (step S12). Thereafter, when the user ID and password are input using the login screen and the login button is clicked, the input user ID and password are transmitted to the server side (step S13). On the server side, when the user can be authenticated with the user ID and password, the data on the menu screen is transferred (step S14).

  When the upload button in the menu screen is clicked, an upload screen request is sent to the server (step S15). Based on the request, the upload input screen data as shown in FIG. 12 is transferred from the server. (Step S16). When the upload button is clicked after designating a file from the input screen, the upload information is transferred to the server (step S17), and the screen data for displaying the upload status is transferred (step S18). The uploading screen as shown in is displayed. Then, the file transfer is actually started from the computer device (step S19), and the ACK signal which is a response confirmation signal and the data of the status display screen are transferred from the server side (step S20).

  The file transfer from the computer device and the ACK signal and status display screen data transfer from the server side are repeated until the file transfer is completed (steps S21 and S22). When the file transfer is completed, the menu screen data is transferred from the server (step S23), and the menu screen display is restored. When the logout button in the menu screen is clicked, the login screen data is transferred. (Step S23), it returns to the initial state.

  As described above, many operations are required to transfer the filed content to the server, which is cumbersome and not preferable for the user. In addition, since detailed procedures and screen configurations displayed in each state differ for each service provider, it is necessary to re-learn the procedures and the like every time the user uses a different service. Even if the service of the same supplier is used, if there is a change in the specification such as version upgrade, there is a possibility that the operation procedure changes or the address of the server to be accessed changes.

  Furthermore, in order to use such a service on the go, for example, it is necessary to possess means for connecting to the Internet, such as a notebook personal computer device, but in order to receive only a data transfer service, Having such a device is inconvenient for the user.

  An object of the present invention is to provide a device such as a personal computer device so that it can be used easily without complicated operations when using a content transfer service via the Internet or the like. .

  The present invention stores data relating to a content server that is connected to a predetermined network and stores content data according to a predetermined procedure, and a communication procedure that is connected to the predetermined network and transfers data between the content server. A communication procedure providing server and a data relay device that can be connected to a predetermined network and communicate with a connected or close information terminal are prepared, and the address of the communication procedure providing server is stored in the data relay device, and further, the address The data relating to the communication procedure transferred from the communication procedure providing server is stored, and data transfer is executed between the information terminal and the content server based on the stored data relating to the communication procedure.

  According to the present invention, the data relay device performs the execution of the procedure of the content storage / sharing service that is a service provided by the Internet provider or the like, and the content storage / sharing service is performed without using a computer device. Become available. Further, it is possible to easily cope with a procedure for using a content storage / sharing service that is different for each provider.

  In addition, by using the technology of the present invention, even when the procedure for using the content storage / sharing service of each provider is updated, it can be easily handled by acquiring the updated procedure. Become.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram showing a system configuration example of this example. In this example, a dedicated data relay device is prepared as means for accessing the server owned by the user. This data relay device is referred to herein as a data transfer agency. The data transfer agency is a device that is used by a user directly connected to an information device (information terminal) that handles content data (or in close proximity to a state where short-distance communication is possible). Information devices include, for example, devices that create content using video signals such as digital still cameras and video cameras, devices that display video content such as video playback devices, and audio signals such as audio recording devices and audio playback devices. A device that handles content and other devices that hold various types of content data can be used.

  In the system configuration example shown in FIG. 1, the information device 10 is shown as a digital still camera. The data transfer agency 20 is configured to be connectable to the information device 10. Specifically, the information device 10 and the data transfer agency 20 are connected with a serial bus cable such as a USB (Universal Serial Bus) method or an IEEE (The Institute of Electrical and Electronics Engineers) 1394 method, or a memory It is connected by an interface using a card slot for cards or the like so that data can be transferred between both devices. Alternatively, data may be transferred between the information device 10 and the data transfer agency 20 that are in close proximity by short-range wireless communication using the Bluetooth (trademark) method, infrared signal transmission, or the like. In the case of a configuration in which the card is mounted in the card slot, the data transfer agency 20 itself may be configured in a card type. In any case, the data transfer agency 20 is preferably configured to be small and light so that it can be easily carried when going out.

  The data transfer agency 20 includes an interface unit (communication means) connected to the Internet, and can be connected to the transmission / reception procedure providing server 30 and the content servers 40 and 50 via the Internet. Address information for connecting to the providing server 30 is stored.

  The content servers 40 and 50 can upload and download data (contents) even when accessed from a general personal computer (not shown in FIG. 1). For example, a data storage service provided by an Internet provider or the like The same server as the conventional one for. The transmission / reception procedure with the content servers 40 and 50 may be executed by any protocol such as the FTP protocol.

  The transmission / reception procedure providing server 30 includes a communication procedure manual storage unit 31. Based on the information stored in the communication procedure manual storage unit 31, the transmission / reception procedure providing server 30 provides information (data transmission / reception procedure information) necessary for communication between the data transfer agency 20 and the content servers 40 and 50. The data transmission / reception procedure information relates to a data transmission procedure between the data transfer agency and the content server, and includes necessary information such as a command flow or software (such as a plug-in). The transmission / reception procedure providing server 30 provides such a data transmission / reception procedure information and a list of content servers 40, 50,... Corresponding to the data transmission / reception procedure information managed by the transmission / reception procedure providing server 30. For example, the content server list is provided as address information of a site (URL) connectable to the server.

  Any one of the content servers 40 and 50 may include the function of the transmission / reception procedure providing server 30. The transmission / reception procedure providing server 30 may provide a list of content servers and address information of a site (URL) into which the transmission / reception procedure information can be input, and the transmission / reception procedure information may be provided by another server.

  FIG. 2 is a diagram illustrating a configuration example of the data transfer agency 20. The data transfer agency 20 transmits the data received from the information device to the content server 40 or 50, and transmits the data received from the content server 40 or 50 to the information device 10, between the information device 10 and the content servers 40 and 50. It is a device that relays data transfer through the network, and has a built-in function to perform web operations performed by the user. The specific configuration shown in FIG. 2 will be described. An interface unit 21 with an information device, a network interface unit 22 for connecting to the Internet, and a control unit that controls data transfer using both interface units 21 and 22. And a storage unit 24 that stores data to be transferred, data related to communication procedures, and connection destination addresses. As the interface unit 21 with the information device, an interface connected by a cable such as a USB system or an IEEE1394 system, an interface connected directly such as a card slot, or an interface for performing short-range wireless communication is used. The network interface unit 22 is an interface for performing communication with the content server and the transmission / reception procedure providing server. For example, the network interface unit 22 is represented by a wired interface represented by Ethernet or a wireless LAN (Local Area Network). A wireless communication interface can be employed. For the storage unit 24, various storage means such as a semiconductor memory and a hard disk can be applied.

  Since the network interface unit 22 of the data transfer agency 20 has a function for performing communication via the Internet, the connected information device 10 side can use network layer protocols such as TCP / IP, web It is not necessary to incorporate access functions, and the data transfer agency 20 performs them for them. The data transfer agency 20 incorporates a basic procedure such as a communication protocol and address information for connecting to the transmission / reception procedure providing server 30 from the beginning, but the transmission / reception procedure with the content servers 40 and 50, the server 40, The address for connecting to 50 is obtained from the transmission / reception procedure providing server 30 and stored in the storage unit 24 for use. The content transmission / reception history is also stored in the storage unit 24.

  Next, a flowchart of the operation when performing data transfer processing using the data transfer agency 20 of this example will be described with reference to FIG. First, when the connected information device 10 generates a request for data transmission or data reception, the data transfer agency 20 receives content server information (name) corresponding to a transfer destination and a transfer source from the information device ( Step ST1). Next, the control unit 23 determines whether or not a content server to be accessed in the future is included in the transmission / reception procedure information list (the content server name corresponding to the stored transmission / reception procedure information or information corresponding thereto) in the storage unit 24. It is confirmed (step ST2), and it is determined whether there is transmission / reception procedure information of the corresponding server (step ST3).

  If the transmission / reception procedure information is not found in the storage unit, the transmission / reception procedure providing server 30 is accessed, and the transmission / reception procedure information is downloaded and stored in the storage unit 24 (step ST4). In step ST5, data is received from the information device, uploaded to the content server, or downloaded from the content server, and transmitted to the information device. At the time of uploading or downloading, it is executed under the control of the control unit 23 according to the procedure using the transmission / reception procedure information stored in the storage unit 24.

  If the transmission / reception procedure information is stored in the storage unit, the transmission / reception procedure providing server is accessed, and the version information of the transmission / reception procedure information of the content server to be accessed is obtained (step ST6). It is determined whether the transmission / reception procedure information in the storage unit is the same as or updated with the version of the transmission / reception procedure information in the transmission / reception procedure providing server (step ST7). Here, when it is not updated, it progresses to step ST5 and performs upload or download according to the procedure using the transmission / reception procedure information memorize | stored in the memory | storage part 24. FIG.

  If the version of the transmission / reception procedure information in the transmission / reception procedure providing server has been updated, the transmission / reception procedure providing server is accessed and the transmission / reception procedure information is downloaded (step ST8). In step ST5, upload or download is executed according to the procedure using the updated transmission / reception procedure information. By performing the processing in this manner, it is possible to cope with the case where the version of the transmission / reception procedure information is updated, and data transfer can always be performed with an appropriate communication procedure.

  As already described, it is expected that the operation of data transfer on the web via the Internet will differ depending on the server to be accessed. In addition, the operation procedure may be changed even on the same server. Therefore, the data transfer agency 20 needs to cope with transmission / reception procedures of the plurality of content servers 40 and 50 as shown in FIG. For this purpose, for example, the data transfer agency 20 downloads list information of content server names (or equivalents) corresponding to transmission / reception procedure information managed in the transmission / reception procedure providing server. Then, a means for allowing the user to select a content server from the list of content servers or a content server name input by the user is confirmed to be included in the list information of the content server. If not included, the user is notified and re-entered. To encourage.

  Next, the data transfer operation by the system of this example will be described with reference to FIG. Here, it is assumed that data transfer is performed with the system configuration shown in FIG. 1, and in the initial state, the data transfer agency 20 to which the information device 10 is connected has never accessed the content servers 40 and 50. Suppose that

  At this time, the data transfer agency 20 first receives data to be transmitted to the content server 40 from the information device 10. Since the content server 40 is accessed for the first time, the transmission / reception procedure information regarding the server 40 is not stored in the storage unit of the data transfer agency 20, so that the data transfer agency 20 sends the transmission / reception procedure providing server 30 to the transmission / reception procedure providing server 30 as shown in FIG. Then, transmission / reception information related to the server 40 is requested (step S1), and transmission / reception procedure information related to the server 40 is downloaded and stored (step S2). An address for accessing the transmission / reception procedure providing server 30 is stored in the data transfer agency 20 in advance.

  Next, as shown in FIG. 4B, the data transfer agency 20 uploads the data received from the information device to the server 40 (step S3). When the transmission completion of each data can be confirmed (step S4), the transmission history is updated to record which data has been transmitted. At the time of this upload, for example, the procedure shown in FIGS. 8 and 9 is executed as a conventional example, and user operations such as inputting a user ID and password, clicking a login button, specifying a file, and clicking an upload button are originally necessary. However, the control unit 23 of the data transfer agency 20 automatically executes these processes based on the transmission / reception information for the server 40 acquired from the transmission / reception procedure providing server 30. The user ID and password are registered in advance in the data transfer agency 20. Or you may make it input using the display part by the side of the connected information apparatus 10 side. As for file designation, data (content) sent from the information device 10 to the data transfer agency 20 is automatically designated. At that time, the data transfer agency 20 may automatically assign a file name.

  Next, it is assumed that the data transfer agency 20 receives data to be transmitted to the server 50 from the information device 10. Also at this time, since the data transfer agency 20 accesses the server 50 for the first time, the transmission / reception procedure information regarding the server 50 is not stored in the storage unit of the data transfer agency 20, and therefore, as shown in FIG. 20 requests transmission / reception procedure information to the transmission / reception procedure providing server 30 (step S5), and downloads transmission / reception procedure information regarding the server 50 (step S6).

  Next, as shown in FIG. 4D, the data transfer agency 20 uploads the data received from the information device 10 to the server 50 (step S7). When the transmission completion of each data can be confirmed (step S8), the transmission history is updated to record which data has been transmitted. At the time of this uploading, for example, the procedure shown in FIGS. 8 and 9 is performed as a conventional example, and user operations such as inputting a user ID and password, clicking a login button, specifying a file, and clicking an upload button are originally necessary. However, the control unit 23 of the data transfer agency 20 automatically executes these processes based on the transmission / reception information for the server 50 acquired from the transmission / reception procedure providing server 30.

  In this way, once the server 40, 50 is accessed, the transmission / reception procedure information is stored in the storage unit of the data transfer agency 20, and thereafter, the access to the server 40, the server 50 is a download of the transmission / reception procedure information. Done without. However, the version update is confirmed, and if updated, the updated data is downloaded. In addition, when access to a new content server is required, it is necessary to obtain transmission / reception procedure information regarding the server from the transmission / reception procedure providing server 30.

  In this way, the data transferred to the content server 40 or 50 can be read by a computer device or the like that has accessed the server 40 or 50, as in the past. Further, the information can be read by the information device to which the data transfer agency 20 is connected without using a computer device.

  In the description of FIG. 4, uploading has been described as an example, but the same processing is performed when downloading from a server.

  Further, the data transfer agency 20 temporarily stores data received from the information device in the storage unit, and for example, disconnects the information device from the data transfer agency 20 and then uses the time available for communication with the content server to transfer the data. May be performed. Then, the data transfer agency 20 may hold information on whether or not the transfer has been completed among the stored data, and may provide it to the user by some method. Further, the data transfer agency 20 may hold information on which data among the data to be transferred has been transferred and provide the information to an information device or the like. By executing these functions, it is possible to present to the user which data has been transmitted and which is still.

Further, the location of the transmission / reception procedure information (location to be managed, server) can be considered several as shown below, but any may be used in the present invention.
Example 1 A server that manages both content server list information and transmission / reception procedure information is installed separately from the content server (as described in the above embodiment).
Example 2 Both content server list information and transmission / reception procedure information are managed in the content server.
Example 3 Content server list information and transmission / reception procedure information are managed on separate servers. For example, this corresponds to the case where transmission / reception procedure information is managed by the content server, and the transmission / reception procedure providing server provides the list information of the content server and the address where the transmission / reception procedure information is stored.

  In the embodiments described so far, the data transfer agency 20 or the like is assumed to be a dedicated relay device configured by hardware. However, for example, a relatively small data processing such as a PDA (Personal Digital Assistants). A program for executing the processing of the present invention may be installed in the device, and the control processing based on the program may function as a similar relay device. In the embodiments described so far, the present invention is applied to a system for transferring data via the Internet. However, any communication means for connecting to the Internet may be used.
