Embodiment 1

[0033] figure 1 The structure of the videoconferencing system provided by Embodiment 1 of the present invention is shown, and for convenience of description, only the parts related to the embodiment of the present invention are shown.

[0034] The remote conference control method provided by the embodiment of the present invention can be applied to the video system, and the video system at least includes:

[0035] A multipoint control unit (MCU) 1 and a plurality of joining terminal devices 2 controlled by the multipoint control unit 1;

[0036] The MCU1 is the control core of the video system. When the number of terminal devices 2 joining the conference is more than two, it needs to be regulated by the MCU1. The MCU1 is connected to the terminal devices 2 and the terminal devices 2 through a network. According to IDO protocol or international standard H.221, H.242, H.243, H.245 and other protocols, MCU1 realizes the exchange and mixing of images and voice, and realizes the c...

Embodiment 2

[0055] figure 2 It shows the implementation process of the remote conference control method provided by Embodiment 2 of the present invention, and the process of the method is described in detail as follows:

[0056] In step S201, when the conference joining terminal receives the interruption conference indication information sent by the multi-point control unit MCU during the video conference, the joining terminal closes its media channel according to the received interruption conference indication information, and saves the channel parameter, enter the standby or hibernation state.

[0057] In this embodiment, the conference joining terminal receives the conference interruption indication information sent by the MCU through the conference control channel during the video conference. Wherein, the interrupted conference indication information is predefined extended conference control information. The media channel includes receiving and sending media channels for sending or...

Embodiment 3

[0062] image 3 It shows the implementation process of the remote conference control method provided by Embodiment 3 of the present invention, and the process of the method is described in detail as follows:

[0063] 1. The multipoint control unit MCU sends a conference interruption instruction message to the conference joining terminal.

[0064] According to the defined extended conference control information, the MCU in this embodiment sends interrupted or resumed conference instruction information to each conference joining terminal to implement conference interrupted or resumed. Among them, the defined extended conference control information (information of the enterprise standard conference control (IDO) protocol) includes but is not limited to the parts shown in Table 1:

Abstract

The invention is suitable for the technical field of communication and provides a teleconference control method, a terminal device, a MCU (Multipoint Control Unit) and a video system. The method comprises the following steps that: while receiving an interrupting conference indicating message sent by the MCU by a conference initiating terminal during the process of teleconference, closing a media channel of the conference initiating terminal and storing a channel parameter by the conference initiating terminal according to the received interrupting conference indicating message, and entering into a standby or dormant state; and while receiving a recovering conference indicating message sent by the MCU by the conference initiating terminal, opening the media channel of the conference initiating terminal and recovering working state by the conference initiating terminal according to the received recovering conference indicating message and the stored channel parameter. According to the method provided by the invention, the interruption and recovery of the conference are quickly and simply realized by sending the indication for interrupting or recovering conference, so that no bandwidth resource is occupied, the loss of conference initiating equipment is prevented and the practicability is higher.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a remote conference control method, a terminal device, an MCU and a video system. Background technique [0002] As a kind of remote conference, video conferencing holds a conference between users at two or more locations through a multipoint control unit (MCU), video input and output devices, and audio input and output devices, and transmits images and images in real time. sound. [0003] In the process of holding an existing video conference, when the user needs to interrupt the meeting due to certain affairs (such as lunch break, dining, etc.), there are only two ways to use: one is to end the meeting and wait for the affairs to be processed before reconvening the meeting. Method 1: During the process of ending the conference, the joining site may be called by other conferences or sites, and the configuration parameters of the site may be changed, which will ...
