Abstract
The method to remote control multi audio/video communication devices by telephone terminal comprises: user calls the interactive voice answering server from different telephone terminals, the server certifies user ID and guides user to input account and password; then, the server displays function menu for selection and decides user selection; if effective, the server interacts with MCU; the latter decides user information, completes operation if effective, and sends result to the server. With control function on background technique, this invention is convenient to user conference.
Description
Technical field
The present invention relates to a kind of telecommunications broadband network audio technology, be specifically related to a kind of method of utilizing telephone terminal remote control multi audio equipment.
Technical background
(Multipoint Control Unit MCU) is the key equipment that the multipoint videoconference service is provided for numerous users on the broadband network to multipoint control unit.On a multipoint control unit, can hold tens even the individual independently multipoint videoconference of hundreds of simultaneously, and the user of these meetings is independent fully, and distributes everywhere on the geography.In this case, multipoint control unit to control very difficulty for so many independent meeting provides instant meeting, or even impossible.
Suppose that a multipoint conference has five participant terminals, these five participant terminals are in different geographical position, are called A terminal, B terminal, C terminal, D terminal and E terminal.Terminal local video picture is called A picture, B picture, C picture, D picture and E picture, as shown in Figure 1.In the process of video conference, the control that each participant terminal is implemented needs an approval that has the conference terminal of highest weight limit, and this conference terminal is exactly chairman.
Under the single-image mode of operation, suppose that the A terminal is chairman, then on B terminal, C terminal, D terminal and E terminal, can see the A picture, hear the sound of A terminal, and be to choose audience's picture in A terminal picture displayed, promptly be one of B picture, C picture, D picture or E picture.If specify the B terminal for choosing the audience, then chairman A terminal shows the B picture, hears the sound of B terminal.At this moment C terminal, D terminal, E terminal are general audience, can only see the video A picture of chairman A terminal.Under the single-image mode of operation, meeting can only have a chairman and one to choose the audience, and a plurality of general audiences can be arranged.
Under four picture mode of operations, each terminal that participates in a conference all shows four corresponding video pictures of terminal institute in five participant terminals on its screen, form the composite video picture.In this composite video picture, have at least three to be the far-end picture.Be any one terminal in the composite video picture, on its screen, can see three far-end pictures and a local picture.Have a terminal to be designated as chairman in the composite video picture, its excess-three terminal is designated as chooses the audience, and the terminal that does not enter the composite video picture is general audience.Under four picture mode of operations, meeting can only have a chairman and three to choose the audience, and a plurality of general audiences can be arranged.
The control of existing multipoint videoconference mostly concentrates on the multipoint control unit, and the right of other participant terminals is very limited.Under the single-image mode of operation, only can realize the far-end video camera control.Terminal can't realize being chosen audience, request Chair, appointment next round chairman or being switched terminal control function demand such as four pictures by general audience application.
At present, popular video terminal product on the market, as ViewStation128, the ViewStation SP of Polycom company, the Media Connect6000 of Vcon company, Media Connect8000 and FalconIP etc. are the endless controlled function all.
The object of the present invention is to provide a kind of method of utilizing telephone terminal remote control multi audio equipment, it has solved the technical problem that terminal in the background technology does not have controlled function.
Technical solution of the present invention is:
A kind of method of utilizing telephone terminal remote control multi audio equipment, its special character is: the performing step of this method comprises:
1) user sends calling from telephone terminal to interactive voice response server 1, and 1 couple of user of interactive voice response server carries out authentication:
(1) interactive voice response server 1 is used the voice guide user, by the telephone keypad input account number and the password of telephone terminal;
(2) account number and the password of 1 pair of user's input of interactive voice response server are compared;
2) after authenticating user identification passes through, the function menu that interactive voice response server 1 usefulness speech play pre-establishes, the user imports the information of selected function by keyboard;
3) information of 1 pair of user-selected function of interactive voice response server is judged, is identified as " effectively selecting ", and then information and the multipoint control unit MCU 3 with user-selected function carries out alternately;
4) 3 pairs of user-selected information of multipoint control unit MCU are judged, are identified as " effectively ", then finish user-selected function operations, and operating result are transferred to user's telephone terminal by interactive voice response server 1.
Above-mentioned telephone terminal can adopt ordinary telephone set, pstn telephone machine, gsm mobile telephone, CDMA mobile phone, IP phone machine or IP video conference terminal etc.The video display terminal of described IP video conference terminal can adopt simulated television and digital television etc.
