Abstract

In an electric conference system using a large-screen display, presentation in an environment with a plurality of portable terminals connected is not taken into consideration. To do this, a host computer for an electric conference system is arranged to store a member ID to specify a terminal, generate a password, display the generated password on a large-screen display and make the password open to participants of a conference, authenticate the terminal on the basis of a member ID and a password, which are contained in a connection request received from the terminal, and process a command received from the terminal on the basis of the authentication result.

Claims (31)

1. A control apparatus for controlling an electric conference system and communicating with a plurality of terminals, the apparatus comprising:

a memory which stores an ID of a member who is permitted to participate in the conference;

a generator, constructed to generate a temporary password common to, and associated with, the plurality of terminals;

a display constructed to display the generated temporary password to make the temporary password open to participants of a conference, wherein the display is different from displays of the plurality of terminals;

an authentication section, constructed for availability for use to authenticate any number of the plurality of terminals based at least on the temporary password common to the plurality of terminals and the ID, which are contained in a connection request received from the terminal; and

a processor, constructed to process a command received from the terminal based on an authentication result from the authentication section,

wherein the authentication section stores a status corresponding to the ID in the memory, and the processor determines based on the status whether the received command is processible.

2. The apparatus according to claim 1 , further comprising a communication section constructed to execute radio communication with a portable terminal.

3. The apparatus according to claim 1 , wherein the processor updates display on the display in accordance with a drawing command contained in the received command.

4. The apparatus according to claim 1 , wherein the display is a large-screen display for conference.

5. A method of controlling an electric conference system using an apparatus which communicates with a plurality of terminals, the method comprising the steps of:

storing an ID of a member who is permitted to participate in the conference in a memory of the apparatus;

generating a temporary password common to, and associated with, the plurality of terminals;

displaying the generated temporary password on a display of the apparatus making the temporary password open to participants of a conference, wherein the display of the apparatus is different from displays of the plurality of terminals;

authenticating any number of the plurality of terminals based at least on the temporary password common to the plurality of terminals and the ID, which are contained in a connection request received from the terminal; and

processing a command received from the terminal based on an authentication result of the authenticating step,

wherein a status corresponding to the ID is stored in the memory in the authenticating step, and it is determined based on the status whether the received command is processible in the processing step.

6. A computer-executable program stored in a non-transitory computer-readable storage medium comprising program code causing a computer to perform a method of controlling an electric conference system using an apparatus which communicates with a plurality of terminals, the method comprising the steps of:

storing an ID of a member who is permitted to participate in the conference in a memory of the apparatus;

generating a temporary password common to, and associated with, the plurality of terminals;

displaying the generated temporary password on a display of the apparatus making the temporary password open to participants of a conference, wherein the display of the apparatus is different from displays of the plurality of terminals;

authenticating any number of the plurality of terminals based at least on the temporary password common to the plurality of terminals and the ID, which are contained in a connection request received from the terminal; and

processing a command received from the terminal based on an authentication result of the authenticating step,

wherein a status corresponding to the ID is stored in the memory in the authenticating step, and it is determined based on the status whether the received command is processible in the processing step.

7. A non-transitory computer-readable storage medium storing a computer-executable program causing a computer to perform a method of controlling an electric conference system using an apparatus which communicates with a plurality of terminals, the method comprising the steps of:

storing an ID of a member who is permitted to participate in the conference in a memory of the apparatus;

generating a temporary password common to, and associated with, the plurality of terminals;

displaying the generated temporary password on a display of the apparatus making the temporary password open to participants of a conference, wherein the display of the apparatus is different from displays of the plurality of terminals;

authenticating any number of the plurality of terminals based at least on the temporary password common to the plurality of terminals and the ID, which are contained in a connection request received from the terminal; and

processing a command received from the terminal based on an authentication result of the authenticating step,

wherein a status corresponding to the ID is stored in the memory in the authenticating step, and it is determined based on the status whether the received command is processible in the processing step.
