BRIEF DESCRIPTION OF THE DRAWINGS FIG.

FIG. 1 shows an embodiment of the present invention, which is a basic system in which a video conference terminal is connected to a multipoint video conference controller at n points via high-speed digital lines e-1 to em. The video conference terminal 11 includes an answer signal selection unit 8 installed at each participant's hand for selecting an answer.
Answer signals j-1 to j- output from the answer signal selection unit
n , a terminal control unit 6 that once collects data and creates data addressed to the multipoint video conference control device 10, and a video switching operation panel 7.
, A display unit 9, and a video signal from the audio / video input / output unit 5.
Signal, audio signal and video switching control signal from the terminal control unit 6.
And multiplexing with the aggregated answer signal
Multiplexed signal from the multipoint video conference controller 10
The video signal, audio signal, and the video switching result
Display system which is video switching result information to be displayed on the panel 7
Control signal and the answer result signal of all TV conference terminals.
And a moving picture coding device 4 for decoding the data separately .

[0008] The multipoint video conference control device 10 is connected to a video conference terminal 11 via a high-speed digital line e-1 to em.
Low bit rate output terminal 4 of the moving picture coding apparatus 4
-2 Total of each video conference terminal 11 sent through
Aggregates are answer signal, and outputs the result of the counting toward video conference terminal, from the television conference terminal 11
The video switching result information switched in response to the video switching request
It comprises a control information analysis unit 2 for outputting to a Levi conference terminal , a video switching / audio processing unit 1, and a line interface unit 3.

The audio / video input / output unit 5 sends a video / audio signal f input from a camera / microphone (not shown) in the conference room to the video encoding device 4, and controls a multipoint video conference. It has a function of receiving the video of the other conference room from the device 10 and the audio after the addition process from the video encoding device 4 and outputting the video to the TV monitor and the speaker in the conference room.

The terminal control unit 6 receives an input from the answer signal selection unit 8.
After once aggregate the answer signal j-1~j-n to be a force, this
Video switching operation panel 7 for the total signal and video switching of
It receives the video switching signal h which is al sent to input as the control signal g of the multipoint video conference control device 10 destined to the low speed bit rate input output terminal 2 of the moving picture coding apparatus 4. In the moving picture coding apparatus 4, after multiplexed video and audio signals f, and the control signal g is encoded and sent to the high-speed digital line e-1. From the video encoding device 4 of the video conference terminal 11
The multiplexed output signal is separated into a video signal a, an audio signal b, and a system control signal d (corresponding to the control signal g) by the line interface unit 3 of the multipoint video conference controller 10.
The control information analyzer 2 analyzes the system control signal d and
If the content is the video switching control signal h, a video switching / audio addition processing control signal c is created and sent to the video switching / audio processing unit 1
If the analyzed content is a response signal for knowing the intentions of all the conference participants by voting during the conference, the response signal is selected by the response signal selection unit 8 of the video conference terminal 11.
Answer signals j-1 to j-n and transmitted from all other conference terminals
The answer signal is totaled, and the result of the aggregation is sent to the line interface unit 3 as a system status signal.

[0011] video signal a, the audio signal b, respectively switching-adding process by the video switching and audio processing unit 1 on the basis of the video switching and audio addition processing control signal c is carried out, the video switching binding
The result information is sent to the system state signal d via the control information analysis unit 2.
It is transmitted all the television conference terminal 11 is sent to the line interface unit 3 via the, high-speed digital line e-1~e- m is connected as. In the television conference terminal 11 has received this, cis, at the terminal control unit 6
The system status signal d is separated and analyzed, and the connection status of the conference room
The system status signal h such as (video switching result information) is output and displayed on the video switching operation panel 7 and the aggregation result signal k is displayed on the display unit 9.

[0012]

[Effects of the Invention] As described above, the present invention provides a multipoint video conference control device having a function for counting responses sent from each video conference terminal, so that it is possible to know the intention of all conference participants by voting. By simply selecting the desired answer from the operation unit provided in front of each conference participant on the conference table, the total is instantly calculated and the result is output to the display of the conference terminal device. Has the effect that the intention of all the conference participants can be quickly and accurately known, and the smooth progress of the conference can be realized.
