  (7) Here, the user in the conference room B selects the shared workspace named “Project X” among the plurality of shared workspaces displayed on the electronic blackboard 22.

  (8) In response to this selection operation, the shared workspace server 30 transmits a list of file references held in the shared workspace 1 to the base server 200. The shared workspace server 30 holds the network address of the base server 200 in order to enable connection between the base servers that have selected the project X of the shared workspace.

  (9) By the above-described procedure, two or more base servers have selected the same shared workspace. For this reason, the shared workspace server 30 issues a request to connect all the registered base servers to other base servers. More specifically, a request to connect to the base server 200 is issued to the base server 100, and a request to connect to the base server 100 is issued to the base server 200.

  (10) The base server 100 and the base server 200 issue a request to connect both video / audio servers, connect the electronic blackboards 12 and 22 to the shared workspace server 30, and share input / output to the application. Start.

  (11) In this embodiment, the base system 10 and the base system 20 hold the video / audio servers 11 and 21, respectively. The base server 100 transmits a request to the video / audio server 11 to receive video and audio from the video / audio server 21. Similarly, the base server 200 transmits a request to the video / audio server 21 to receive video and audio from the video / audio server 11.

  (12) The video / audio server 11 starts receiving video and audio from the video / audio server 21, and the video / audio server 21 starts receiving video and audio from the video / audio server 11. FIG. 10 shows a state in which the video and audio data received from the video server at the other site are output to each site on the electronic blackboards 12 and 22.

(13) Here, it is assumed that the user selects the file P via the graphical user interface presented on the electronic blackboard 12 of the base system 10. In response to this, an application associated with the file is started in the shared workspace server 30.

  (14) The shared workspace server 30 transfers the screen display performed by the application to the electronic blackboards 12 and 22 in the base systems 10 and 20.

  (17) When the user operating the electronic blackboard 12 instructs to end the application, the file used in the application is stored in the shared workspace. Or you may store in the file server (not shown) which the reference on a shared workspace instruct | indicates.

  (18) In the base server 200, the user instructs the logout from the base server 200 and the end of use by connecting the IC card 2. As a result, the base server 200 ends the session.

  (19) In the base server 100, the user instructs the logout from the base server 100 and the end of system use by moving the IC card outside the card recognizable range of the card reader 13.

  Next, each procedure described above will be described in more detail. First, an authentication procedure performed using the IC card 2 possessed by the user in order to use the remote conference system 1 will be described with reference to FIG. In the following description, the operation of the base system 10 is described as an example, but the base system 20 performs the same operation as the base system 10.

  In order to use the remote conference system 1, the user must log in to the system by reading the user information of the IC card 2 into the card reader 13 for authentication. The IC card 2 stores, for example, personal information such as a user's name and department, user information such as a password, authentication data, a user ID, and a user's face photo.

  The card reader 13 reads user information from the IC card 2 and transmits it to the base server 100. The base server 100 records the user information read by the card reader 13 in the authentication unit 103, extracts authentication data from the user information, and transmits it to the user database 40 via the communication control unit 106. In the user database 40, data for authenticating a user who can use the remote conference system 1 is recorded. For example, the secret key issued by the certification authority is recorded in the user database 40, and it is determined whether the user is a legitimate user by authenticating with the public key read from the IC card 2. When the authentication is successful, the user database 40 transmits certificate data certifying that the corresponding user is an authorized user who can use the system to the base server 100.

  If the authentication is successful, the site server 100 logs in to the shared workspace server 30 using the certificate data transmitted from the user database 40. When the shared workspace server 30 receives a login request with a certificate from the base server 100, the shared workspace server 30 receives the request. The shared workspace server 30 receives the login request and transmits file selection screen data to the base server 100. The screen data is data for the user to select a file to be displayed on the electronic blackboard 12. The meeting body selection screen data shown in FIG. 14 and the file list screen data shown in FIG. 18 correspond to this.

  Next, a communication procedure for selecting a conference body and performing a remote conference will be described with reference to FIG.
