In one embodiment, as shown in Fig. 2, providing a kind of video conference processing method, it is applied to include at least two The cascade system of grade system, every primary system include at least one video conferencing system, each video conferencing system is corresponding to be connected Connect at least one terminal, comprising the following steps:
It step 202, will when the Request System in cascade system receives the key frame request of institute's connection request end transmission The system of key frame request is received as current level system, by including in the acquisition key frame request of current level system Requested end mark.
It is understood that generally requiring to carry out video conferencing system " classification fraction " mode in some conventions Construction and maintenance, i.e., carry out planning construction by administrative division or grade for whole system, units at different levels are responsible for safeguarding itself video While conference subsystem, and the video conference subsystem that control has units at different levels under its command can be dispatched.
Such as: an institution system is divided into provincial, city-level, district grade, township level, and provincial system can hold whole system In comprising all juniors and can terminal convention, and township level system can also hold the participant in itself compass of competency end The mini-session at end.It just needs to set up tree-like cascade video conferencing system at this time.
Video conferencing system refers to the system for video conference.Cascade system is referred to by least two different stages Video conferencing system composition system.The system that Request System refers to receiving the key frame request of request end transmission.Quilt Request end mark refers to the mark of requested end corresponding to the key frame data of request end request, as second level request end A is asked The key frame data asked is the key frame data of level-one terminal B, then terminal B is requested end, and B is requested end mark.In grade In connection system, superior system can have at least one lower system, and any one lower system can only have a superior system.
In one embodiment, it may include at least one server in each video conferencing system, server is corresponding Connect at least one terminal.When the request server in cascade system receives the key frame request of institute's connection request end transmission When, using the server for receiving key frame request as current level server, key frame is obtained by current level server The requested end mark for including in request.
As shown in figure 3, the cascade system includes four ranks, primary server is the server of highest level, and level-one is whole End 1 and level-one terminal 2 are the terminals directly connecting with primary server, and secondary server is that primary server is connected Next level servers.Second level terminal 1, second level terminal 2 and second level terminal 3 are the terminals directly connecting with secondary server, and And three tier server is next level servers that secondary server is connected.Three-level terminal 1 and three-level terminal 2 are directly with three The terminal of grade server connection, and level Four server 1 and level Four server 2 are next rank clothes that three tier server is connected Business.Level Four terminal 1 and level Four terminal 2 are the terminals directly connecting with level Four server 1.Level Four terminal 3 and level Four terminal 4 are straight Connect the terminal connecting with level Four server 2.
Key frame data refers to the frame data comprising an entire screen information in video data.Terminal obtains crucial After frame data, key frame data can be decoded to obtain the complete picture in video data.In video data, further include Distinguish frame data.Difference frame data refer to the frame data with distinctive information existing for a upper key frame data.Frame will be distinguished Data are overlapped with key frame data, it can obtain the frame data of complete picture.
Request end is when carrying out screen switching, if being not received by the key frame data of new video flowing, can not decode Generate complete video pictures.Therefore, request end needs to generate key frame request Concurrency and send to requested end, to get pass Key frame data.It request end can be by screen switching to new data flow according to key frame data.
The server of any one rank can receive the key frame request that the corresponding terminal of the server is sent.Work as grade When request server in connection system receives the key frame request of institute's connection request end transmission, key frame request will be received Server obtains the requested end for including in key frame request by current level server and marks as current level server Know.
Step 204, when requested end, which identifies corresponding requested end, is not attached to current level system, prime is worked as in judgement Whether other system is in the highest level in cascade system.
In a system, each of mark and the system that store all terminals connecting with the system are melted Close video data identification.Fusion video data identification refers to the video data all the way for being fused into the video data of multiplex terminal Mark.Requested end identifies the mark that can be each terminal, is also possible to merge the mark of video data, without being limited thereto.
After current level system receives key frame request, the requested end mark in key frame request is obtained, and should Requested end mark is matched with each mark stored in current level system.When successful match, then it represents that the quilt Request identifies corresponding requested end and connect with current level system.When matching unsuccessful, indicate that the requested mark corresponds to Requested end be not attached to current level system, then judge the superlative degree whether current level system is in cascade system Not.
In one embodiment, it when in current level system comprising at least one server, is corresponded to when requested end identifies Requested end when being not attached to current level server, judge the highest whether current level server is in cascade system Rank.
After current level server receives key frame request, the requested end mark in key frame request is obtained, and will Requested end mark is matched with each mark stored in current level server.When successful match, then it represents that This is requested the corresponding requested end of mark and connect with current level server.When matching unsuccessful, the requested mark is indicated Know corresponding requested end and be not attached to current level server, then judges whether current level server is in cascade system Highest level.
Step 206, when current level system is not at the highest level in cascade system, key frame request is sent to The other system of the upper level being connected with current level system, and return and execute system using key frame request is received as working as prime Other system step.
In cascade system, when current level is not at highest level, key frame request is sent to and current level The connected other system of upper level of system, and return to execute and walk the system for receiving key frame request as current level system Suddenly.
In one embodiment, when current level server is not at the highest level in cascade system, by key frame It requests to be sent to the other server of upper level being connected with current level server, and return to execution to receive key frame request Server is as current level server step.
Step 208, when current level system is in the highest level in cascade system, key frame is requested downward step by step The system for being sent to the participation video conference of current level system junior, until finding the corresponding system in requested end.
When current level system is in the highest level in cascade system, key frame request is sent down to step by step and is worked as The system of the participation video conference of preceding level-systems junior in this way can be with until finding the corresponding system in requested end In all systems that key frame request is sent in the cascade system.Wherein, the lower system of each system can have more It is a, and may include the system for participating in video conference in lower system, it also may include the system for having neither part nor lot in video conference.Cause This, each system only needs to request key frame to be sent to the system for participating in video conference.
In one embodiment, it may include at least one server in each video conferencing system；Work as current level When server is in the highest level in cascade system, key frame request is sent down to current level server junior step by step Participation video conference server, until finding the corresponding server in requested end.
When current level server is in the highest level in cascade system, key frame request is sent down to step by step The server of the participation video conference of current level server junior, until finding the corresponding server in requested end, Key frame can be requested in the Servers-all being sent in the cascade system in this way.
It is understood that when current level is not at highest level, if by key frame request be sent to currently The lower level servers for the participation video conference that rank is connected, and it is corresponding in each lower level servers lookup requested end mark Requested end.Each lower level servers, and the lower service are all not attached to when requested end identifies corresponding requested end When device is the lowest level in cascade system, key frame request is sent to connected upper level by each lower level servers Other server.And when upper level other server connection be multiple lower level servers when, then the other server of upper level will Multiple key frame requests are received, the waste of computer resource is caused.
As shown in figure 3, three-level terminal 1 initiates key frame request to three tier server, the requested end in key frame request It is identified as second level terminal 1, when three-level terminal, which does not find requested end, identifies corresponding requested end, which is requested It is sent in each other server of next stage, i.e., key frame request is sent to level Four server 1 and level Four server 2.Level Four server 1 and level Four server 2 do not find requested end and identify corresponding requested end, and level Four server 1 With the lowest level that 2 place rank of level Four server is in cascade system, then level Four server 1 and level Four server 2 are to three Grade server sends key frame request.Therefore, three tier server can receive level Four server 1 and level Four server 2 is sent Two identical key frames requests, cause the waste of computer resource.
When above-mentioned example uses above-mentioned video conference processing method, when three-level terminal does not find requested end mark pair When the requested end answered, key frame request is sent in the other server of upper level, i.e., is sent to key frame request Secondary server.Secondary server only receives the key frame request of junior, has saved computer resource.
Even if requested end is identified in the junior of current level, can also be realized using above-mentioned video conference processing method Save computer resource.For example, second level terminal 1 initiates key frame request to secondary server, it is requested in key frame request End is identified as three-level terminal 1, and when second level terminal, which does not find requested end, identifies corresponding requested end, which is asked It asks and is sent in the other server of upper level, i.e., key frame request is sent to primary server.Primary server is not searched Identify corresponding requested end to requested end, and rank where primary server is the highest level in cascade system, then to Secondary server sends key frame request.
After secondary server receives key frame request, it is corresponding requested that lookup requested end mark is carried out again End.When second level terminal, which does not find requested end, identifies corresponding requested end, key frame request is sent to next stage In each other server, i.e., key frame request is sent to three tier server.Three tier server equally only receives two The key frame request that grade server is sent.
Step 210, it using the corresponding system in the requested end found as requested system, is obtained by requested system The key frame data that requested end is sent, and key frame data is sent to the request end that Request System connects.
When a system searching in cascade system identifies corresponding requested end to requested end, by requested end pair The system answered is as requested system.The key frame data that requested end is sent is obtained by being requested system, and by the key Frame data are sent to Request System step by step.Key frame data is sent to by request end by Request System again.
In one embodiment, it may include at least one server in each video conferencing system；By what is found The corresponding server in requested end obtains the key frame that requested end is sent as requested server, by being requested server Data, and key frame data is sent to the request end that request server connects.
When a server in cascade system, which finds requested end, identifies corresponding requested end, by requested end Corresponding server is as requested server.The key frame data that requested end is sent is obtained by being requested server, and The key frame data is sent to request server step by step.Key frame data is sent to by request end by request server again.
Above-mentioned video conference processing method, in cascade system, by key frame request, first superior is sent step by step, works as highest When the system of rank does not still find the corresponding requested end in requested end, then key frame request sent to junior step by step Until finding the corresponding requested system in requested end.The key frame data of requested end is sent out by being requested system It send to Request System, then key frame data is sent to by request end by Request System, to realize the video council across rank View.
In one embodiment, when current level system is not at the highest level in cascade system, key frame is asked Seek the other system of the upper level for being sent to and being connected with current level system, comprising: when current level system is not in cascade system Highest level when, obtain the first network type of current level system, and the upper level being connected with current level system is other Second network type of system；When first network type is consistent with the second network type, key frame request is sent to and is worked as The connected other system of upper level of preceding level-systems.
Different systems can have different network types, such as different local area networks, Metropolitan Area Network (MAN), wide area network.When current When level-systems are not at the highest level in cascade system, obtain current level system first network type, and with work as Second network type of the connected other system of upper level of preceding level-systems.When first network type is consistent with the second network type When, key frame can be requested to be sent to the other system of upper level being connected with current level system.
In the present embodiment, when current level system is not at the highest level in cascade system, when current level system When the first network type of system is consistent with the second network type of the other system of upper level, key frame request is sent to and works as prime The connected other system of upper level of other system, realizes the video conference between the identical network type across rank.
In one embodiment, it when current level server is not at the highest level in cascade system, obtains current The first network type of level servers, and the second network class of the other server of upper level being connected with current level server Type；When first network type is consistent with the second network type, key frame request is sent to and is connected with current level server The other server of upper level.
Different servers can have different network types, such as different local area networks, Metropolitan Area Network (MAN), wide area network.When working as When preceding level servers are not at the highest level in cascade system, the first network type of current level server is obtained, with And the second network type of the other server of upper level being connected with current level server.When first network type and the second network When type is consistent, key frame can be requested to be sent to the other server of upper level being connected with current level server.
In one embodiment, when current level system is not at the highest level in cascade system, prime is worked as in acquisition The first network type of other system after the second network type of the other system of the upper level being connected with current level system, is also wrapped It includes: when first network type and the second network type are inconsistent, key frame request being sent to and is connected with the other system of upper level Cascade gateway, wherein cascade gateway be used for connect different network type system；Key frame is requested to send out by cascade gateway It send to the other system of upper level.
When first network type and the second network type are inconsistent, can not be counted between the system of different network type According to interaction.Therefore, it is necessary to cascade networks to correlate the system for connecing different network type.When first network type and the second network type When inconsistent, key frame request is sent to the cascade gateway being connected with the other system of upper level, then will be crucial by cascade gateway Frame request is sent to the other system of upper level.
In one embodiment, above-mentioned video conference processing method further include: when first network type and the second network class When type is inconsistent, key frame request is sent to the cascade gateway being connected with the other server of upper level, wherein cascade gateway is used for Connect the server of different network type；Key frame request is sent to the other server of upper level by cascade gateway.
When first network type and the second network type are inconsistent, can not be carried out between the server of different network type The interaction of data.Therefore, it is necessary to the servers that cascade network connection connects different network type.When first network type and the second network When Type-Inconsistencies, key frame request is sent to the cascade gateway being connected with the other server of upper level, then pass through cascade gateway Key frame request is sent to the other server of upper level.
Further, as shown in figure 4, the cascade network Central Shanxi Plain may include a pair of of simulation terminal, i.e. home court simulation terminal and visitor Field simulation terminal.Home court simulation terminal is connected with the other server of upper level, and visiting field simulation terminal is connected with next level servers. Simulate data sharing between terminal and visiting field simulation terminal in home court.For example, when home court simulation terminal receives data A, visiting field Simulation terminal also receives data A simultaneously；When visiting field, simulation terminal receives data B, home court simulation terminal also receives simultaneously To data B, and home court simulation terminal and visiting field simulation terminal can receive different data simultaneously.
When first network type and the second network type are inconsistent, key frame is requested to send out by current level server It send to the cascade network Central Shanxi Plain being connected with the other server of upper level, that is, is sent to the visiting field that the cascade network Central Shanxi Plain is connected with current level Simulate terminal.At the same time, the home court simulation terminal in the cascade network Central Shanxi Plain also receives key frame request, and the key frame is asked Seek the other server of upper level for being sent to and being connected with home court simulation terminal.
