[Means to solve the problem]

The multipoint video conference device of this invention has input/output terminals for video and audio signals, and a system It has low-speed bit rate input/output terminals for inputting and outputting control signals for high-speed Encoding/multiplexing of video signals, audio signals, and control signals by interfacing with digital lines A television equipped with a video encoding device that separates/decodes the received multiplexed signal. A conference terminal and a plurality of said video conference terminals are accommodated through a high-speed digital line. The low-speed bit rate output from the low-speed bit rate output terminal of the video encoding device When the video signal is received and analyzed, and the video signal is switched based on the analysis result. Both perform addition processing on audio signals and send system status signals to the video conference terminal. In a multipoint video conference device having a multipoint video conference control device for transmitting, Answer signal selection means for selecting an answer signal for the video conference terminal, and this answer. Sending the selected output signal to the low-speed bit rate input/output terminal of the video encoding device. In addition, each video conference terminal received from the multipoint video conference control device transmits terminal control means for outputting the total result of the answer signals to a display device; The selected outputs sent individually by the video conference terminal to the multipoint video conference control device are recorded. Each video conference terminal is equipped with a response standard means that aggregates power signals and outputs the aggregate results. The answer signals of all participants received from the The results of the aggregated responses are displayed on the display device, and all participants reach a consensus or vote.

【Example】

Next, the present invention will be explained with reference to the drawings.

[0007] Figure 1 shows an embodiment of the present invention, in which the video conference terminal is a multipoint video conference control device. The basic system is connected to n points through high-speed digital lines e-1 to e-m. It is mu. A video conference terminal 11 is installed at each participant's hand for answer selection. The response signal selection unit 8 and the selection signals from these response signal selection units are once aggregated and multiplied. A terminal control unit 6 that creates data addressed to the point video conference control device 10 and a video switching operation An operation panel 7, a display section 9, and a video encoding device 4 that encodes/multiplexes various signals. It consists of

[0008] The multi-point video conference control device 10 communicates via high-speed digital lines e-1 to e-m. The low-speed bit rate input/output terminal 4-2 of the video encoding device of the video conference terminal 11 The signals sent from the terminal are aggregated, and the aggregated signals are sent to the terminal. A control information analysis section 2 for outputting results, a video switching/audio processing section 1, and a line It consists of an interface section 3.

[0009] The audio/video input/output unit 5 receives input from a camera and microphone (not shown) in the conference room. The video/audio signal f sent to the video/audio signal f is sent to the video encoding device 4, and the multipoint video conference Video from other conference rooms from the control device 10 and audio after addition processing are sent from the video encoding device 4. It has the function of receiving and outputting it to the TV monitor and speakers in the conference room.

0010 The terminal control section 6 selects the answer signals j-1 to j-n selected by the answer signal selection section 8. The video sent from the video switching operation panel 7 for video switching after being aggregated once. Multiplexed with switching/control signal h, and control signal g addressed to multipoint video conference control device 10. and input it to the low-speed bit rate input terminal 4-2 of the moving image encoding device 4. moving image In the encoding device 4, after encoding and multiplexing the video/audio signal f and the control signal g, Send to high-speed digital line e-1. Video encoding device 4 of the video conference terminal 11 These output signals are sent to the line interface section 3 of the multipoint video conference control device 10. It is separated into a video signal a, an audio signal b, and a system control signal d. Control information analysis section 2 Next, we will create the video switching/audio addition processing control signal c, and we will also create a vote during the meeting. When determining the intentions of all conference participants, the response signal selection section of the video conference terminal 11 The signals j-1 to j-n selected by 8 are aggregated for all other conference terminals, and The total results and the system status signal are sent to the line interface unit 3.

[0011] The video signal a and the audio signal b are displayed based on the video switching/audio addition processing control signal c. The image switching/audio processing unit 1 performs switching and addition processing, and the line interface are sent to the bus unit 3 and connected via high-speed digital lines e-1 to e-n. It is transmitted to all the video conference terminals 11. Each video conference terminal 11 that received this On the side, the output control information of the multipoint video conference control device 10 is transmitted to the terminal control unit 6. The system status signal h, which is separated and analyzed and shows the connection status of the conference room, is sent to the video switching operation panel. The total result signal k is outputted and displayed on the display unit 9 at the screen 7 and the total result signal k, respectively.
