The server connection information storage device 20 stores connection information (URL or IP address, login ID, password, etc.) of a server that transmits image information to the STB 10 via the wide area communication network 34, in this embodiment. To do.

  The CPU 14 includes a QR code generation function 22 that generates a graphic code indicating various information such as connection information stored in the server connection information storage device 20, for example, a QR code (trademark).

  Modern mobile phone networks can be connected to the Internet. In the present embodiment, an arbitrary mobile phone 40 can be connected to the wide area communication network 34 via the mobile phone network 36. The mobile phone 40 includes a network interface 42 connected to the mobile phone network 36, a CPU 44 that controls the whole, operation keys 46, a camera 48, and a storage 50. The CPU 44 includes a QR code analysis function 52 that analyzes or decodes the QR code captured by the camera 48.

  Further, a user information management server 60, a presentation management server (PM server) 70, and a file server 90 in the company network are connected to the wide area communication network 34. Of course, the file server 90 is connected to the wide area communication network 34 through a gateway that manages data transfer from the inside to the outside and vice versa. However, since it is not related to the operation of this embodiment, in FIG. Nasty gateways are omitted.

  The user information management server 60 includes a network interface 62, a CPU 64 that manages the whole, and a user information storage device 66 that stores user information.

  The presentation management server (PM server) 70 includes a network interface 72, a CPU 74 for managing the whole, a storage 76, and a progress management information storage device 78 for storing progress management information. The CPU 74 has a conversion function 80 for converting a presentation file into an image.

  The file server 90 includes a network interface 92, a CPU 94 that manages the whole, and a storage 96 that stores files.

  FIG. 2 shows an operation flow of this embodiment. The operation of this embodiment will be described in detail with reference to FIG.

  The set-top box 10 accesses the user information management server 60 at power-on and at regular intervals, receives server connection and service use authentication via the wide area communication network 34, and connects to the PM server 70 at that time. Information is acquired (S1). The connection information to the PM server 70 includes a URL (Universal Resource Locator) of the PM server 70, a login ID, and a password. The STB 10 stores the acquired connection information in the storage device 20.

  A person who wants to give a presentation at the STB 10, for example, a sales engineer, instructs the STB 10 to display connection control information of the PM server 90 using an operation device or a remote control device (not shown) of the STB 10. In response to this instruction, the CPU 14 of the STB 10 reads the server connection information from the storage device 20, and generates a QR code indicating the server connection information, the identification information of the STB 10, and the one-time password by the QR code generation function 22. The generated QR code is applied to the video monitor 30 by the image output device 16 as connection control information and displayed (S2).

  At the same time, the STB 10 requests the PM server 70 to establish a session for transferring image data, and notifies that there is an access request using the one-time password. The identification information of the STB 10 includes information necessary for establishing a session between the PM server 70 and the STB 10, and includes, for example, the IP address of the gateway 32 and the IP address of the STB 10, or the network interface 12 of the STB 10 It consists of a MAC address. By requesting a connection from the STB 10 to the PM server 70, the STB 10 can receive image data from the PM server 70 even when a firewall that controls access from the wide area communication network 34 is set in the gateway 32.

  A user such as a sales engineer takes a picture with the camera 48 of the mobile phone 40 that brings the QR code displayed on the screen of the video monitor 30 and analyzes it with the QR code analysis function 52. Thereby, the connection information for connecting to the PM server 70, the identification information of the set top box to be used, and the one-time password for accessing the PM server 70 are set in the mobile phone 40. Thus, the sales engineer can access the PM server 70 using the mobile phone 40 (S3). Of course, it is obvious that part or all of the connection information to the PM server 70 may be displayed on the screen of the video monitor 30 as characters and the sales engineer may manually input the information to the mobile phone 40.

  The PM server 70 compares the identification information of the STB 10 added to the session establishment request from the STB 10, the one-time password, and similar information added to the access request from the mobile phone 40, and if both match ( S4) A communication path for image data transmission is established with the STB 10, and access to the mobile phone 40 is permitted (S5). If they do not match, the session establishment request from the STB 10 is rejected, and the access from the mobile phone 40 is rejected.

  When the file to be disclosed is stored in the storage 50 of the mobile phone 40, the user transfers the file from the mobile phone 40 to the PM server 70 (S6). When the file to be disclosed is stored in the in-house file server 90, the file server 90 is also accessed by the mobile phone 40, and the target file is transferred from the file server 90 to the PM server 70 via the wide area communication network 34.

  The PM server 70 converts the received file into an image file by the presentation file conversion function 80, and stores the received presentation file and the image data file obtained by the conversion in the storage 76 (S7). When the storage in the storage 76 is completed or the first page image can be transmitted, the PM server 70 transmits the first page image data to the STB 10 (S8). The STB 10 temporarily stores the image data transmitted from the PM server 70 in the memory 18, converts the image data into a video format that matches the video format of the video monitor 30 by the image output device 16, and supplies the video format to the video monitor 30. As a result, the first page of the presentation file is displayed on the screen of the video monitor 30.

  Using the mobile phone 40, the user transmits a presentation file progress message (forward and backward, etc.) to the PM server 70. The PM server 70 stores the progress of the received presentation file in the progress management information storage device 78, and transmits the image data of the designated page to the STB 10 according to the message from the mobile phone 40 (S9). In this way, an arbitrary page of the presentation file is displayed on the screen of the video monitor 30 connected to the STB 10, and the display page is switched as if the mobile phone 40 is a remote control device of the STB 10. be able to.

  When ending the presentation, the user notifies the PM server 70 of the end with the mobile phone 40 (S10). Following this notification, the PM server 70 deletes the presentation file and its image data file from the storage 76, and disconnects the session with the STB 10 and the mobile phone 40 (S11).

  Although an example of a presentation file for page turning has been described, the present invention can also be applied to a file having a content such that a series of images are continuously displayed, such as a moving image. It is only necessary to instruct the PM server 70 from the mobile phone 40 to perform operations equivalent to the playback stop, pause, fast forward, and rewind of the video equipment.

  When the presentation file is transferred from the file server 90 to the PM server 70, the file server 90 may be provided with a function for converting the presentation file into an image.

  In addition, the STB 10 receives the presentation image from the PM server designated by the STB 10 at the presentation location. Of course, the STB 10 may receive the image data from the PM server designated by the user. In this way, the file after the end of the presentation can be surely erased, and leakage to others can be easily prevented. That is, it is easy to ensure the confidentiality of the file contents. For this purpose, first, for example, using the wireless communication function of the mobile phone 40 or, if equipped, the infrared communication function or the short-range wireless function, the address of the PM server and information for use ( The login ID and password are notified to the STB 10, and the STB 10 uses the connection information to access the designated PM server and request transmission to itself.

  Although the invention has been described with reference to specific illustrative embodiments, various modifications and alterations may be made to the above-described embodiments without departing from the scope of the invention as defined in the claims. This is obvious to an engineer in the field to which the present invention belongs, and such changes and modifications are also included in the technical scope of the present invention.
