Embodiment
Set up tripartite video call:
Use ICP/IP protocol to be connected to the intercommunication server after the indoor set start by network addressing.
Create video conference mode,, ask to set up tripartite video call when caller indoor set A (as Fig. 1, down together) calls out to called indoor set B, C.
A sends request instruction earlier and " requires to set up B, C video call with indoor set " to the intercommunication server.Whether " intercommunication server " receives the requirement of transmitting A respectively to B, C after the request instruction of A at this moment, after instruction is transmitted in B, the C service of receiving, is presented on the screen, accepted request by resident family's decision.After determining to accept, indoor set will be opened audio frequency, video and coding/decoding module.Receive code stream, decoding output image and audio frequency.
Indoor set A, B, the tripartite video intercom simultaneously of C are realized.
Application adds video call in many ways:
Indoor set D need add in the video call, only needs D resident family to click " video conference " in touch-screen control and checks the video conference tabulation;
In video conference tabulation, select to want the video conference that adds, add video conference with authentication (authentication be divided into do not have authentication adds, cipher authentication adds, invite the people to authenticate).
D will send out to the intercommunication server and apply for adding in many ways instructing in the video call;
Server determines whether to allow D to add video conference according to authentication;
When server authentication D provide authentication code legal after, allow D to add video conference;
Indoor set D will open audio frequency, video and coding/decoding module.Receive code stream, decoding output image and audio frequency.
Application adds video call foundation in many ways.
Invitation adds video call in many ways:
Need add in the video call as need indoor set E, can invite indoor set to add in touch-screen control by A (video conference founder or participant invite) resident family equally.
A will send out to invite and add E to instructing in the video call in many ways to the intercommunication server;
After receiving the invitation instruction that A sends, server is forwarded to E,
This moment, E determined that reception invitation adds video call request in many ways,
After accepting the invitation, indoor set E will open audio frequency, video and coding/decoding module.Receive code stream, decoding output image and audio frequency.
Invitation adds video call foundation in many ways.
Intercom system of the present invention needs at least that 3 indoor sets are above, intercommunication server and local area network (LAN) are formed, and indoor set and the communication of intercommunication server utilize local area network (LAN), carry out the transmission of voice and image, adopts this framework to realize tripartite or video intercom technology in many ways.The indoor set digital data transmission is used ICP/IP protocol international standard technology.
Below by embodiment and in conjunction with the accompanying drawings to tripartite or in many ways simultaneously the video intercom method and system be described in further detail.In fact this function has just added the video conference function in existing digital visual intercommunication, uses functions such as inviting, apply for adding video conference flexibly.
As shown in Figure 1: be system architecture diagram of the present invention, native system is mainly by needing three or many indoor sets, local area network (LAN), an intercommunication server at least.A, B, C, D, E are five indoor sets among its figure, a station server and local area network (LAN), and indoor set uses local area network (LAN) to be connected with the intercommunication server.Indoor set and intercommunication server numeral signal utilize the local area network (LAN) transmission, and use ICP/IP protocol international standard technology.
As shown in Figure 2: be indoor set video conference surface chart of the present invention, the left side is a conference participation tabulation resident family list.Central authorities then are resident family's conference participation video images, the video image frame can be according to how much change (Fig. 2 be shown as 4 frames) of the number of participation, to be shown as 6 frames (wherein surplus frame is that black does not have demonstration) in the time of 5 people's conference participations, 8 people participate in meeting will show 8 frames.The central authorities below is that microphone and volume are adjusted button, and indoor set changed the audio frequency input/output module over to after touch screen was clicked, and then the input and output volume is made adjustment.Right-hand for inviting resident family and withdraw from conference button, touch screen is clicked and is invited and input needs a building of inviting and room number, waits for that the other side adheres to video conference and finishes invitation, and touch screen is clicked to withdraw from and directly withdrawed from video conference.
As shown in Figure 3: be workflow diagram of the present invention, brief introduction is as follows respectively.
1. establishment video conference, and send to server,, video conference will be kept in the server then prompting failure of video conference failure if setting up successful list of videos.
2. wait that the resident family that is invited accepts after the video conference, indoor set will be opened the Voice ﹠ Video module, and encoding and decoding, and send code stream to server by network.
3. when invitation or application added video conference after video conference was set up, determine whether to allow to add according to authentication code.
Authentication code by and open audio-video device, receive code stream, decoding output participant's image and audio frequency, and receive the stream sign indicating number from server.
5. authentication adds the video conference failure not by then getting back to the demonstration local video.
As shown in Figure 4: the RJ45 Network Interface Module of indoor set links to each other with CPU MII interface, and all input are all handled by CPU MII interface, and the RJ45 interface connects the switch local area network (LAN), and then by local area network (LAN) and server communication.Be sent to CPU MII interface through the RJ45 interface and be sent to CPU when data flow enters indoor set, CPU sentences the processing input information.Send it to CPU MII interface after CPU finishes with regard to Data Stream Processing again, CPU MII interface is forwarded to opposite equip. with data flow by the RJ45 interface.
