Description

Video conferencing system

This utility model relates to the equipment of conference rooms for conducting video-audio conferences. The objective of this technical solution is to build such a system that would provide convenient access for each user by means of controlling video-audio equipment and the interaction of all conference participants. In addition, the system must have a reliable interconnection of all nodes and devices and ease of maintenance.

The technical conditions of the videoconferencing system are known, including video cameras and a rear table installed in the conference room with seats for conference participants equipped with personal terminals (US 5272526 from 12/21/1993).

There are also known systems for holding videoconferences with the possibility of providing video and audio communication between conference participants, video cameras and monitors are located on the table top, at which the participant sits (DE 404.1319 A, 07/02/1992).

Video conferencing systems are also known for transmitting video and audio signals between a central studio and several external studios (DE 4142550).

The closest analogue of the claimed technical solution in the form of a utility model is a video-audio communication system, presented in the application DE No. 2836884 of 06.03. 1980 which describes a device containing a round table for conference participants and a device for receiving and transmitting images and audio signals, as well as control panels of these devices located at the workplaces of participants.

A disadvantage of the known system is that at each workplace of a conference participant it is necessary to install a video camera and a screen, and the installation of this equipment in the manner indicated in the device (above the table surface) will not allow the participant to observe other participants, because will obscure them.

The claimed technical solution eliminates such drawbacks by the fact that a common controllable PTZ camera and large screens for collective viewing are used, installed in planes to which the line of sight of the participants of the corresponding sides of the main screen is 1 normal.

Workplaces of conference participants are placed around a controlled PTZ camera and screens mounted on the frame mainly below the mutual viewing line of participants located opposite each other and below the table surface, if used.

This mutual arrangement will allow all participants to directly observe each other. At the same time, the system includes an attribution unit with a conference system that connects the participants' consoles to the control unit for a PTZ camera and video switching.

Figures 1 and 2 show a system for video conferencing.

Workplaces 1 for participants are located around a controlled PTZ camera 2 installed in the central part of the studio, on the frame 3 where several video conferencing display devices are also installed in the form of screens 4. Video camera 2 and screens 4 are connected to the camera control and video signal switching unit 5.

The system includes individual remotes 6 with a microphone 7, a speaker and a headphone jack. Individual remotes 6 are installed on the ground 1 of the conference participants and are connected to the control unit of the conference system (COP). 8. The control unit 8 individual remotes is connected to the control unit 5 of the video camera

and video switching. The control unit 8 (CC) can be connected to a device 9 for receiving and transmitting video signals to remote conference participants and device 10 for switching audio signals. A video recording device 11, for example, a video recorder, a video signal receiving and transmitting device 9 to remote conference participants, and other video signal sources or receivers can be connected to the video camera control and video switching unit 5. Each of the individual remotes 5 has a headphone jack and an organ for selecting an audio signal (simultaneous translation channel).

The system operates as follows.

Before starting work, in the control unit 5 of the video camera 2 and the switching of the video signal, as well as in the controlled new-turn video camera 2, the settings used to record the workplace 1 of each conference participant are saved. When you turn on the microphone 7 of the individual remote control installed on the workplace 1 of the conference participant, the control unit 8 (CC) transmits information about this through the 4-control video camera and video switching unit to the controlled PTZ camera 2. Using the stored information, the controlled PTZ camera 2 induces and removes that participant whose last microphone is turned on.

The video signal of the controlled PTZ camera 2 can be supplied to devices connected to the camcorder control and video signal switching unit 5, including screens 4, a video signal recorder, and a video transmit-receive device 8 which has been sent to a remote participant. Thus, all conference participants, including remote participants, can view the video image of the participant whose last microphone was turned on. Conference participants can view the video signals on the screens, as well as from other devices connected to the control unit 5 of the PTZ camera and video switching. The choice

the source of the video signal is carried out by the operator using the unit 5 control PTZ camera and switching signals.

The control system of the conference system can broadcast to users of individual controllers 6 several audio signals received from different sources through the device 10 switching audio signals.

Conference participants through the speakers of the consoles or headphones connected to the consoles 6 can listen to the speeches of other participants or other audio signals received by the conference control unit through the audio switching unit 5.

Speeches of conference participants through the control unit of the conference system and the switching unit of the audio signals can be transmitted to the receiving unit 12 of the transmission of the audio signal to the remote receiver or other consumers of the audio signal.

The choice of the audio signal for listening, for example, broadcasting in one of the languages of simultaneous translation, is carried out using the control body located on the individual remote control 6 of the conference participant.

Screens 4 can be made in the form of plasma panels, the size and location of which allow for a clear display of video signals during a video conference.
