Description
Technical field
The present invention relates to video conferencing technology field, be specifically related to a kind of digital home videos conference system based on p2p.
Background technology
Video conferencing system (Video conferencing System) is to utilize communication network, transmits a kind of communication system of multiple participant's continuously active images, sound and data.Compared with videoconference, have that intuitive is strong, the advantage such as contain much information.The terminal in each meeting-place is interconnected by communication network, receive image, the voice and data in other meeting-place, in multiple spot (more than two terminal) meeting situation, the multipoint control unit (Mutlipoint Control Unit be called for short MCU) of the personnel that attend a meeting by video conferencing system control meeting process, arbitrarily browse the other side meeting-place, watch meeting-place panorama or spokesman close-up shot, talk discussion; Video conference not only can be heard sound, can also see participant, makes each participant have sense on the spot in person; Participant also can exchange by the mode of text chat; Conference system provides abundant data, services by Data Control agreement for participant, as: file transfer, electronic whiteboard, desktop are shared and application program is shared etc.
Along with the high speed development of communication network, the application of video conferencing system is more and more extensive: provide far-end both sides or in many ways immediately and person to person interview, the most direct benefit is to save time and various meeting expenses, and improves meeting efficiency; Improve with promote commercially exchange, customer service, product development and product introduction; Support remote teaching, technical training, tele-medicine and the consultation of doctors; New tool of market survey, information retrieval, scientific research cooperative, engineering design, employee's recruitment etc. is provided.
Along with the development of IP technology, IP network and the enhancing of personal computer disposal ability, IP-based video conferencing system is come out, and it is powerful, and cost is lower, is current the most widely used conference system.The framework that IP-based video conferencing system often adopts has C/S (Client/Server, client/server) and B/S (Browser/server browser/server) structure.But the video conferencing system of existing two kinds of patterns is all reliance server, audio/video information is transmitted, very large to the pressure of server, user not only need to pay great hardware cost on server, and due to the restriction of server bandwidth resource, the transmission quality of audio/video information is not high.There are problems in the C/S model of double-layer structure, for example development and maintenance cost is high, server load weight, and very flexible, lacks openly, is difficult to integrate with etc. with Internet/Intranet, causes the many difficult problems in system operation and maintenance.Although the B/s pattern of three layers exploitation and maintenance are comparatively easy, server load weight, convention goer's quantity can be a lot of in theory, and actual effect is also unsatisfactory, and server becomes the bottleneck of conference system.
The framework that IP-based video conferencing system often adopts has C/S (Client/Server, client/server) and B/S (Browser/server browser/server) structure.But the video conferencing system of existing two kinds of patterns is all reliance server, audio/video information is transmitted, very large to the pressure of server, user not only need to pay great hardware cost on server, and due to the restriction of server bandwidth resource, the transmission quality of audio/video information is not high.There are problems in the C/S model of double-layer structure, for example development and maintenance cost is high, server load weight, and very flexible, lacks openly, is difficult to integrate with etc. with Internet/Intranet, causes the many difficult problems in system operation and maintenance.Although the B/s pattern of three layers exploitation and maintenance are comparatively easy, server load weight, convention goer's quantity can be a lot of in theory, and actual effect is also unsatisfactory, and server becomes the bottleneck of conference system.
Existing video conferencing system is all generally based on C/S model, it need to install client-side program on every computer, use very inconvenient, and platform dependence is strong, portable poor, be difficult to realize cross-platform, certainly, also having partial video conference system is based on B/S pattern, but all need to download, extra plug-in unit is installed, convenience still has much room for improvement, and plug-in unit itself is third party software, user may enter unsafe website in order to download, thereby there is potential safety hazard to a certain degree, and, the video conferencing system of existing two kinds of patterns is all that reliance server transmits audio/video information, very large to the pressure of server, user not only need to pay great hardware cost on server, and due to the restriction of server bandwidth resource, the transmission quality of audio/video information is not high.
Therefore, be necessary to provide a kind of digital home videos conference system based on p2p to solve the defect of prior art.
Summary of the invention
The object of this invention is to provide a kind of digital home videos conference system based on p2p, it is easy to use, and platform transplantation is good, safe, not only greatly reduces cost, and audio/video information transmission quality is high.
Therefore, the invention provides a kind of digital home videos conference system based on p2p, comprise a master server and multiple server zone and multiple client from server composition, described master server, be provided with p2p link block from server and client side, for from server with master server, client and be connected from setting up p2p between server; Described master server and all have respectively the index of other server resource from server, for exchange message; Described master server is for the scheduling from relation between server and client; The described Synchronization Control that is used for reception, storage, processing, forwarding and the audio frequency and video of audio frequency and video from server, text chat and file transfer; Described client be provided be carried on browser and for play the flash module of the audio and video information that other client sends, for gather corresponding client audio-frequency information audio collecting device, for gather corresponding client video information video acquisition device, for the sending module from the flash module of service or other client by the audio and video information collecting and under sending to; Described client successfully connects from server, setting up p2p by the p2p link block of server with other client is connected, the audio and video information that the sending module of client gathers audio collecting device and video acquisition device is processed through coding, is directly sent in the flash module in other client and is play by the Internet.
Preferably, described client is provided with and logs in module, carries out logon operation during from server for connecting in client.
