Embodiment
Below, with reference to accompanying drawing and embodiment, the present invention is described further：
Referring to Fig. 1, the present invention provides a kind of method for realizing intercommunication between video conference, is mainly used in gateway unit,
The gateway unit includes signaling transfer module, video conversion module and audio conversion module, signaling transfer module, Video Quality Metric mould
Block and audio conversion module are connected with software terminal, hard terminal；Signaling transfer module specifically includes WEBRTC (WebReal-
TimeCommunication) communication entity, signaling resolution module and SIP (Session Initiation Protocol) communications
Entity, three is sequentially connected, and WEBRTC communication entities are connected with software terminal, and SIP communication entities are connected with hard terminal.Software terminal example
Such as it is PC or browser of mobile terminal, hard terminal can entity video conference terminal, the processor such as including MCU.
Comprise the following steps that：
S1：Signaling transfer module receives the request signal from software terminal, and the request signal parse to obtain meeting
Address and messaging parameter, and invitation signal is sent to hard terminal, the invitation signal carries meeting address and messaging parameter；
The request signal of software terminal is actually initiated by user, and user inputs IP address, meeting address and meeting on software terminal
Password is discussed, by then generating request signal in software terminal after checking.IP address is used to select corresponding gateway unit.Meeting address
Namely meeting number, with uniqueness, a unique video conference is selected according to meeting number, sets up long-range with the video conference
Connection.Pass through the legitimacy of meeting password authentification user, it is ensured that the safety of meeting.Messaging parameter is that software terminal is carried out with hard terminal
Communication needs the parameter consulted, and the video code model that such as software terminal is used is VP8, and audio coding formats are ISAC, these
Messaging parameter informs hard terminal, if hard terminal can be received, and both can set up connection.All these information are all encapsulated in
In request signal, gateway unit is parsed to these information, and actually request signal is received by WEBRTC communication entities first,
Signaling resolution module is transmitted to, is parsed by signaling resolution module, the meeting address is called eventually through SIP communication entities,
Namely join with corresponding hard terminal and believe.
S2：Hard terminal judges whether to receive communication according to messaging parameter, if receiving, and feedback agrees to signal of communication to signaling
Modular converter, and perform S3；Otherwise, feedback disagrees signal of communication to signaling transfer module；
Hard terminal continues next step if the messaging parameter that can receive software terminal, if can not receive, can not build
Vertical connection.
S3：Signaling transfer module sets up signal of communication to software terminal according to agreement signal of communication feedback one, leads to software terminal
Cross gateway unit to be connected with hard terminal foundation, and receive encoded video and audio coding signal from software terminal；
In actually interaction, said process may be by could repeatedly consult to complete.After hard terminal agreement messaging parameter,
Show that software terminal and hard terminal can carry out Signalling exchange, pass on message to software terminal by signaling transfer module, afterwards software terminal
Set up and be connected with hard terminal, video conference can be carried out.
S4：Video conversion module is sent after the encoded video from software terminal is decoded to hard terminal, audio
Modular converter is sent after the audio coding signal from software terminal is decoded to hard terminal；
S5：Video conversion module is received after the encoded video from hard terminal is decoded and sent to software terminal, sound
Frequency modular converter is received after the audio coding signal from hard terminal is decoded and sent to software terminal.
Gateway unit all can both receive regarding for software terminal as terminal, its video conversion module and audio conversion module
Frequency encoded signal, audio coding signal, can also receive the encoded video and audio coding signal of hard terminal, and all right
These encoded videos, audio coding signal are decoded is forwarded to the opposing party again.It is achieved in traditional meeting and WEBRTC
Between conversion, both WEBRTC and traditional meeting is organically blended, facilitate user to be added to by software terminal such as PC, browsers
In conventional video meeting, do not limited by place, place, can freely increase participant number.
Still further aspect, referring to Fig. 2, the present invention also provides a kind of system for realizing intercommunication between video conference, and it includes soft
Terminal, hard terminal and gateway unit, the gateway unit include signaling transfer module, video conversion module and audio modulus of conversion
Block, signaling transfer module, video conversion module and audio conversion module are connected with software terminal, hard terminal.Wherein, Signalling conversion
Module specifically includes WEBRTC communication entities, signaling resolution module and SIP communication entities, and three is sequentially connected, WEBRTC communications
Entity is connected with software terminal, and SIP communication entities are connected with hard terminal.
Signaling transfer module is used to receive the request signal from software terminal, and the request signal parse to obtain meeting
Address and messaging parameter, and invitation signal is sent to hard terminal, the invitation signal carries meeting address and messaging parameter；Firmly
Terminal is used to be judged whether to receive communication according to messaging parameter, if receiving, and feedback agrees to signal of communication to signaling transfer module,
And signaling transfer module sets up signal of communication to software terminal according to agreement signal of communication feedback one, software terminal is passed through gateway unit
Set up and be connected with hard terminal, and receive encoded video and audio coding signal from software terminal；Otherwise, feedback is disagreed
Signal of communication is to signaling transfer module；Video conversion module sent after the encoded video from software terminal is decoded to
