Abstract

A system and method for controlling multipoint video conference, a video terminal and a central control subsystem are provided by the present invention. The system includes a central control subsystem and a video terminal at the conference place side, and central office equipment at the network side. The central control subsystem is configured to transmit a multipoint video conference control command to the video terminal; the video terminal is configured to transmit the received multipoint video conference control command to the central office equipment at the network side; the central office equipment is configured to control the video terminal of each conference place according to the received multipoint video conference control command. The scheme of the present invention maintains the good usability of the central control subsystem and guarantees the safety and the stability of the central office system.

Claims

1. A method for controlling multipoint video conference, comprising:

a central control subsystem at a conference place side directly transmitting a multipoint video conference control command to a video terminal;

the video terminal, after directly receiving the multipoint video conference control command from the central control subsystem, directly transmitting the received multipoint video conference control command to central office equipment at a network side; and

the central office equipment, after directly receiving the multipoint video conference control command from the video terminal, controlling the video terminal of each conference place according to the received multipoint video conference control command.

2. The method according to claim 1, wherein, the step of the central control subsystem directly transmitting the multipoint video conference control command to the video terminal comprises:

a touch screen of the central control subsystem receiving the multipoint video conference control command input by a user, and notifying a central control server in the central control subsystem, and the central control server directly transmitting the multipoint video conference control command to the video terminal.

3. The method according to claim 1, wherein,

the multipoint video conference control command is a multipoint video conference initiation command, a multipoint video conference ending command, an adding new conference place command, a deleting conference place command, an applying master control conference place command or a video broadcast command.

4. The method according to claim 2, wherein,

the multipoint video conference control command is a multipoint video conference initiation command, a multipoint video conference ending command, an adding new conference place command, a deleting conference place command, an applying master control conference place command or a video broadcast command.

5. The method according to claim 1, wherein the multipoint video conference command carries a parameter of a participant participating the conference.

6. A system for controlling multipoint video conference, comprising a central control subsystem and a video terminal at a conference place side and central office equipment at a network side;

wherein,

the central control subsystem is configured to directly transmit a multipoint video conference control command to the video terminal;

the video terminal is configured to directly receive the multipoint video conference control command from the central control subsystem, and directly transmit the received multipoint video conference control command to the central office equipment at the network side; and

the central office equipment is configured to directly receive the multipoint video conference control command from the video terminal, and control the video terminal of each conference place according to the received multipoint video conference control command.

7. The system according to claim 6, wherein,

the central control subsystem comprises a touch screen and a central control server;

the touch screen is configured to receive the multipoint video conference control command input by a user, and notify the central control server;

the central control server is configured to directly transmit the multipoint video conference control command to the video terminal.

8. The system according to claim 6, wherein,

the multipoint video conference control command is a multipoint video conference initiation command, a multipoint video conference ending command, an adding new conference place command, a deleting conference place command, an applying master control conference place command or a video broadcast command.

9. The system according to claim 7, wherein,

the multipoint video conference control command is a multipoint video conference initiation command, a multipoint video conference ending command, an adding new conference place command, a deleting conference place command, an applying master control conference place command or a video broadcast command.

10. The system according to claim 6, wherein the multipoint video conference command carries a parameter of a participant participating the conference.

11. A video terminal, used for controlling multipoint video conference, characterized in that the video terminal comprises a special interface for performing information interaction with a central control subsystem;

and

the video terminal is configured to directly receive a multipoint video conference control command from the central control subsystem through the special interface, and directly transmit the multipoint video conference control command to central office equipment at a network side.

12. The video terminal according to claim 11, wherein,

the multipoint video conference control command is a multipoint video conference initiation command, a multipoint video conference ending command, an adding new conference place command, a deleting conference place command, an applying master control conference place command or a video broadcast command.

13. The video terminal according to claim 11, wherein the multipoint video conference command carries a parameter of a participant participating the conference.

14. A central control subsystem, used for controlling multipoint video conference, characterized in that the central control subsystem comprises a special interface for performing information interaction with a video terminal, and the central control subsystem comprises a touch screen and a central control server, wherein,

the touch screen is configured to receive a multipoint video conference control command input by a user, and notify the central control server;

and

the central control server is configured to directly transmit the multipoint video conference control command to the video terminal through the special interface,

wherein the multipoint video conference command carries a parameter of a participant participating the conference.

15. The central control subsystem according to claim 14, wherein,

the multipoint video conference control command is a multipoint video conference initiation command, a multipoint video conference ending command, an adding new conference place command, a deleting conference place command, an applying master control conference place command or a video broadcast command.
