Embodiment
Be illustrated in figure 1 as the embodiment of the present invention one and control the method schematic diagram of video conference.Have voice channel between terminal and multipoint control unit (MCU), this voice channel both can the transmitting conference voice, and voice are controlled in the meeting that also can transmit to control meeting.The concrete steps that the present embodiment is controlled video conference are as follows:
The encoded voice that step 101:MCU receiving terminal sends;
Step 102:MCU decodes to the encoded voice that receives;
Step 103:MCU identifies the meeting control command from decoded voice;
MCU identifies voice, can adopt special voice recognition processing algorithm, input the relevant information of voice by analysis, and controlling voice messaging with the meeting that prestores compares, both equate or similar just judgement input voice are controlled voice for the corresponding meeting that prestores, and control meeting control command corresponding to voice thereby the corresponding MCU of going out is inner with this meeting.
Step 104: if identify the meeting control command, MCU directly carries out corresponding meeting control operation according to this meeting control command.
In order to realize that more accurately voice can control, MCU can also send to terminal to the meeting control command that identifies from voice before step 104, and by terminal feedback to the user.Terminal can by captions on screen to user's display conference control command, also the meeting control command can be passed through voice feedback to the user.The user of end side passes through remote controller or feed back the meeting control command that shows at the WEB interface, as confirming to select "Yes", otherwise selects "No".Terminal sends to MCU to the result of user feedback, and MCU operates according to the result of user feedback.If the feedback result of receiving is to confirm, MCU carries out corresponding meeting control operation according to this meeting control command, otherwise does not process.
