Abstract

PURPOSE:To allow a participant of a conference to easily confirm from which terminal equipment a picture in reception comes by superimposing the name of a participant point at which a terminal equipment relating to information is arranged. CONSTITUTION:Plural terminal equipments 30 are connected to a controller 10 via a line network 20. The terminal equipments 30 are arranged to each participation point (conference room). Each terminal equipment 30 is provided with a terminal equipment section 31 sending and receiving conference information to/from the controller 10, a monitor display device 32 connected to the terminal equipment section 31 and being an output section outputting received conference information and with a superimposing circuit 33. Moreover, each terminal equipment section 31 is registered with a participant point name in advance. The superimposing circuit 30 participant point information to be sent at all times and stores the newest information and when the circuit 33 receives a participant point number sent at the changeover of reception picture information, the circuit 33 retrieves the participant point name corresponding to the number, converts the name into character information and displays the information onto the monitor display device 32.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multipoint conference system, and more particularly, to a function of notifying a name of a participation point of a terminal participating in a conference.

[0002]

2. Description of the Related Art Generally, this type of system includes a terminal device arranged at different participation points (meeting rooms) for transmitting and receiving conference information, and a control device connected to the terminal device via a line network. Have. The control device selectively distributes conference information to be transmitted / received from each terminal device.

The conference information includes image information and audio information. The image information is projected to the participants of the conference by a monitor / display which is an image signal output means provided in each terminal device. At this time, the lamp on the controller arranged at each participation point was used to indicate which terminal device the captured image belongs to.

[0004]

However, the conventional multipoint conferencing system has a drawback in that it is difficult for the participant to determine which terminal the image being received is because the image is identified by the lamp of the controller. ..

An object of the present invention is to provide a multipoint conference system in which participants of a conference can easily confirm which terminal device the image being received belongs to.

[0006]

According to the present invention, in a multipoint conference system having a display unit for displaying predetermined information, the name of the participation point where the terminal device relating to the information is arranged is superposed. By doing so, a multipoint conference system characterized in that a superimposing circuit for displaying on the display section is provided can be obtained.

Further, according to the present invention, the multipoint system selects one terminal device from the plurality of terminal devices connected via a line network and receives the information transmitted by the one terminal device. Then, the information is transmitted to all the other terminal devices, and the participation point name and the participation point number corresponding thereto are transmitted to all the other terminal devices, and the participation of all the other terminal devices. A multipoint conference system having a control unit for transmitting point name data and the participation point number to the terminal device, wherein the superimposing circuit receives the information and the participation point number. can get.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing this embodiment.

In FIG. 1, a plurality of terminal devices 30 are connected to a control device 10 via a line network 20. The terminal device 30 is arranged at each participating point (meeting room).
The terminal device 30 is also connected to the terminal device 31 for transmitting / receiving the conference information to / from the control device 10, a monitor / display 32 which is an output unit for outputting (displaying) the received conference information, and is described later. Superimpose circuit 33
Have and. In addition, a participation point name is registered in advance in each terminal unit 31.

When the terminal device 30 is connected to the control device 10 (when a new participation is made), the terminal portion 31 transmits the participation point name data to the control device 10. The control device 10 allocates the participation point number (meeting room number) to the participation point name data, and distributes it to all the other participating terminal devices 30 together with the received participation point name data. On the other hand, the terminal device 30 newly joined
In response, the participation point information (participation point number and participation point name) of all the terminal devices 30 currently participating is transmitted. When the terminal device 30 leaves, the participation point number of the leaving terminal device 30 is transmitted to all participating terminal devices 30.
The terminal device 30 is connected to another terminal device 3 via the control device 10.
Image and sound are exchanged with 0, and the image information is displayed on the monitor display 32, but the participation point information is separated and sent to the superimposing circuit 33. The superimposing circuit 33 always updates the stored participation point information to the latest one and stores it. However, when receiving the participation point number that is sent when the received image information is switched, it is set to that number. The corresponding participation point name is searched, converted into character information, superimposed on the composite signal from the terminal device 30, and displayed on the monitor display 32.

As described above, the name of the participation point is superimposed and displayed on the monitor display and confirmed by the participants of the conference.

[0013]

According to the present invention, since the name of the participation point is superimposed and displayed on the monitor display of each terminal device, it is possible to confirm at a glance which terminal device the image being received belongs to. can do.
