JPH05207456A - Multi-point video conference controller indicating statistic of number of utterance - Google Patents

Abstract

PURPOSE:To easily display the statistic of number of times of utterance and to allow the system to grasp the degree of understanding in the education system employing a video conference by employing a counter storing number of times of utterance and a superimposing function onto a monitor. CONSTITUTION:Voice signals inputted from each microphone are synthesized by mixers A-4, B-4 and the mixed signal is sent to a line. Each point television conference controller 7 uses a level detection circuit 8 to detect a voice signal level sent from each conference room and selects a video image of a conference room in which a larger sound durates for a long time and distributes and sends it to each conference room. Then a signal used for selecting the conference rooms is inputted to a counter control section 9 to increment relevant counters 10. The count is stored to store number of times of utterance of conference rooms. Furthermore, the reserved data are optionally read and superimposed on reception monitors A-3, B-3 installed to each conference room for the display.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention connects conference terminals in a plurality of conference rooms arranged at distant points via a multipoint video conference control device for managing and controlling the entire conference, and video,
More particularly, the present invention relates to a multi-point video conference control device for displaying statistics of the number of times of speech in a video conference system capable of performing a video conference between remote points by voice.

[0002]

2. Description of the Related Art A video conference system using a conventional multipoint video conference control device is shown in FIG.

In FIG. 2, a transmission image A taken by any one of the cameras is a camera changeover switch A-1.
Is input to the image encoding device A-6 via. The image encoding device A-6 outputs the input transmission image A to the transmission image monitor A-2 in its room, encodes the image data, and sends it to the line. Also, the received image B from the other party
Is output from the line to the reception image monitor A-3 via the image encoding device A-6.

On the other hand, the audio signal A input from the microphone of the own room is input to the image encoding device A-6 after being synthesized by the audio mixer A-4. Image coding device A-6
Then, the input voice signal A is encoded and transmitted to the line.

The multipoint video conference controller 7 synthesizes the audio signals of all the conference rooms collected as described above, and then distributes and sends them to each conference room. At that time, the conference room in which a louder sound continues for a long time is detected by the audio level detection circuit 8, and the image of the conference room is selected and sent to each conference room.

[0006]

In the above-mentioned conventional multipoint video conference control device, the voice of the speaker is automatically detected and the video is switched, and the transmitted voice is transmitted from all conference rooms participating in the conference. It just synthesized the voice and sent it to each conference room.

The present invention has been made in view of the above-mentioned conventional circumstances, and therefore an object of the present invention is to provide a novel multipoint video conference control device capable of grasping the degree of understanding in education etc. using a video conference. To do.

[0008]

In order to achieve the above object, a multipoint video conference control apparatus according to the present invention stores a voice level detection circuit for detecting a voice level transmitted from each conference room and a number of utterances. Counter, a counter control unit for writing and reading to the counter, and a superimpose function for displaying on a monitor.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the accompanying drawings with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

Referring to FIG. 1, 10 is a counter corresponding to each conference room. The transmission image A captured by any one of the cameras is input to the image encoding device A-6 via the camera changeover switch A-1. The image encoding device A-6 outputs the input transmission image A to the transmission image monitor A-2 in its own room, encodes the image data, and sends it to the line. Also, the received image B from the other party is received from the line via the image encoding device A-6, and received image monitor A-
3 is output.

On the other hand, the audio signals input from the microphones are combined by the audio mixers A-4 and B-4 and sent to the line. The multipoint video conference control device 7 detects the level of the audio signal transmitted from each conference room by the audio level detection circuit 7, selects the video of the conference room in which a louder sound continues for a long time, and sends it to each conference room. Distribute and send. A signal for switching the conference room is input to the counter control unit 9, and the corresponding counter 10 is incremented. By saving this counter value, the number of times of speech in the conference room is stored.

Further, the stored data can be arbitrarily read and superposed and displayed on the reception monitors A-3 and B-3 installed in each conference room.

[0014]

As described above, according to the present invention,
By using a counter that stores the number of times of utterance and a superimpose function on the monitor, it is possible to easily display the statistics of the number of times of utterance, and it is possible to grasp the degree of comprehension in education such as video conferencing. can get.
