Description
Technical field
The present invention relates to communication technical field, particularly a kind of way of recording of videoconference and equipment.
Background technology
Along with the widespread deployment of IP network and the development of ip voice technology, voip session is progressively more and more used in enterprise as a kind of meeting solution of economical and efficient, has improved the efficient of people's communications, cooperation greatly.
The means that meeting exchanges as a kind of many people, minutes are necessary often, and for voip session, the recording of voip session is exactly a kind of form of minutes.In the application scenarios of reality, the recording of voip session requires also to need to finish the storage of recorded message, and can further realize the multiple functions such as backup, management, retrieval and broadcast to recording file except that the content of meeting is recorded.
With respect to the traditional PSTN network, conference call data is through encoding process, and after carrying out the IP packing, transmits on IP communication network (local area network (LAN), wide area network), rather than on traditional means of twisted pair copper silk thread, carry out.
Therefore, the voip session recording can not adopt traditional record type of making contact to realize, and is corresponding, recording technologies such as the built-in sound-recording function of meeting, mirror image packet capturing occurred.
One of existing voip session recording scheme is to adopt the technology of mirror image packet capturing, in the network architecture as shown in Figure 1, recording server and voip session server are received on the Ethernet switch simultaneously, Port Mirroring function by switch, the Port Mirroring that the voip session server is connected is to the port that recording server connected, recording system can be caught the speech data of all of the port like this, records.
In realizing process of the present invention, the applicant finds that there is following problem at least in prior art:
1, the mirror image packet capturing recording technology of prior art requires Ethernet switch that image feature is arranged, and needs configuration mirroring port on request, and configuration is changed bigger to user's existing network.
2, the mirror image packet capturing recording technology of prior art needs a plurality of voice flows of mirror image, each conferenced party that participates in videoconference all provides a voice flow, merge (if only choose a certain voice flow by recording server then, that recording does not just have the sound of corresponding participant), such technical scheme causes last session recording and actual meeting difference to occur.
For example,,,,, can only hear the audio mixing of B, C, D so for A selecting A, B, C, D audio mixing sometime if audio mixing is carried out in Dynamic Selection four directions wherein for the videoconference that has A, B, C, D, E, F six sides to participate in, in like manner:
B can only hear A, C, D audio mixing,
C can only hear A, B, D audio mixing,
D can only hear A, B, C audio mixing,
And E, F can hear the complete audio mixing of A, B, C, D.
The audio mixing that record E, F receive but this does not mean that just can be realized the recording to videoconference, because, also there is the another one problem, be exactly that audio mixing side is a Dynamic Selection.That is to say, at another constantly, may select other cubic audio mixing.If by mirror image packet capturing recording, can represent the actual conditions of whole meeting with can not find a stream.
And, do not record except selecting an existing stream, can not for example, carry out audio mixing once more to the file behind the audio mixing if desired by existing stream reprocessing, perhaps all can not realize the audio mixing of making a speech again etc.
Because according to existing technical scheme, if need be the audio mixing once more of the file behind the audio mixing, the echo phenomenon will appear, be B+C+D, A+C+D, A+B+D, several streams such as A+B+C and A+B+C+D mix once more, with same sound occurring repeatedly problem can appear, if joining day in the slightly different step, echoing will take place.
On the other hand, if need carry out audio mixing, will need recording system to do in strict accordance with the audio mixing strategy and the algorithm of conference system to original speech.But, in the operating process of reality, allow recording system and conference system strictness be consistent, implementing difficulty can be very big, and this is equivalent to rebuild a conference system in recording system.
