Step 1012a: inquire whether there is client features code from the fixing multimedia content library preset.
It should be noted that, fixing multimedia content library in step 1012a is arranged in client, be previously stored with in this fixing multimedia content library can each fixing multimedia content of implementation information Push Service starting the condition code corresponding to remote media play signal when playing, and the playing duration (fixing multimedia content is played from start to and terminates duration) corresponding to each fixing multimedia content, in this fixing multimedia content library, each fixing multimedia content is at the playing duration one_to_one corresponding of the condition code started corresponding to remote media play signal when playing and fixing multimedia content.
In step 1012a, by inquiring about the client features code whether existing and get in above-mentioned steps 1011a in the fixing multimedia content library preset, thus learn that whether the content of the current broadcasting of client is can the fixing multimedia content of implementation information Push Service.
When inquiring about in less than above-mentioned steps 1011a the client features code got from fixing multimedia content library, then the content of the current broadcasting of client does not belong to fixing multimedia content, does not now need to carry out information pushing; When inquire from fixing multimedia content library there is the client features code got in above-mentioned steps 1011a time, then current start to play can the fixing multimedia content of implementation information Push Service for client, now performs step 1013a.
Step 1013a: obtain the moment that client receives the remote media play signal corresponding with client features code, to start broadcasting the moment as client.
In step 1013a, obtain client and receive moment of the remote media play signal corresponding with client features code, using the moment T1 that starts broadcasting as client, namely obtain this fixing multimedia content when client is actual start to play when.
Alternatively, also comprise after step 1013a:
Step 1014a: obtain the playing duration corresponding with client features code from fixing multimedia content library, using the playing duration as fixing multimedia content.
In step 1014a, the playing duration corresponding to the current fixing multimedia content starting to play of client can also be obtained based on fixing multimedia content library, in follow-up flow process, client finish time be calculated.
It should be noted that, the remote media play signal received by client in above-mentioned steps 1011a ~ step 1013a and be stored in the fixing multimedia content library of client to obtain carving method when client starts broadcasting, it is only a kind of possibility in the application, and the application can also adopt additive method to obtain carving method when client starts broadcasting.
Fig. 3 is another internal process figure of step 101 in the embodiment of the present invention one, and as shown in Figure 3, as another possibility, step 101 comprises:
Step 1011b: generate corresponding server feature code according to the remote media play signal that server receives.
In step 1011b, first carry out by capture card the remote media play signal that acquisition server is currently received, wherein the type of capture card is consistent with collected remote media play signal type, such as, when be sampled remote media play signal type be picture signal and/or audio signal time, this capture card can be correspondingly picture signal capture card and/or audio signal sample card; Then the remote media play signal collected for capture card generates corresponding client features code.Wherein, the data type of server feature code comprises: the combination of finger image or audio-frequency fingerprint or finger image and audio-frequency fingerprint.
Step 1012b: inquire whether presence server condition code from the fixing multimedia content library preset.
It should be noted that, the content that fixing multimedia content library in step 1012b stores with the fixing multimedia content library in above-mentioned steps 1012a completes identical, content for the fixing multimedia content library in step 1012b see description corresponding in above-mentioned steps 1012a, can repeat no more herein.But, different from the fixing multimedia content library in step 1012a but, fixing multimedia content library in step 1012b is arranged at server, inquires about for server feature code corresponding to the remote media play signal received server.
When inquiring about in less than above-mentioned steps 1011b the server feature code got from fixing multimedia content library, then the content of the current broadcasting of server does not belong to fixing multimedia content, now cannot determine whether the content of the current broadcasting of client belongs to fixing multimedia content, does not carry out information pushing to client; When inquire from fixing multimedia content library there is the server feature code got in above-mentioned steps 1011b time, then current start to play can the fixing multimedia content of implementation information Push Service for server, and the situation of now corresponding client has three kinds:
One, delay inequality between client and server be on the occasion of time, namely the remote media play signal that client receives lags behind server (for same remote media play signal, server first receives, receive after client), now, then client does not also start the fixing multimedia content of the current broadcasting of Play Server.
They are two years old, when delay inequality between client and server is 0, namely the remote media play signal that client receives is synchronized with server (for same remote media play signal, server and client side synchronously receives), now, then client just in time starts the fixing multimedia content of the current broadcasting of Play Server.
They are three years old, when delay inequality between client and server is negative value, namely the remote media play signal that receives of client prior to server (for same remote media play signal, client first receives, receive after server), now, then fixing multimedia content a period of time of the client current broadcasting of Play Server.
Start broadcasting the moment for obtaining client, then when inquire from fixing multimedia content library there is the server feature code got in above-mentioned steps 1011b time, continue perform step 1013b.
Step 1013b: obtain the moment that server receives the remote media play signal corresponding with server feature code, to start broadcasting the moment as server.
In step 1013b, obtain server and receive moment of the remote media play signal corresponding with server feature code, to start broadcasting the moment as server, namely obtain this fixing multimedia content when server is actual start to play when.
Step 1014b: obtain the delay inequality between client and server.
In step 1014b, any one can be adopted in prior art to obtain delay inequality between the two for the method obtaining delay inequality between client and server, and detailed process is the application be no longer described in detail.
Step 1015b: calculate client start broadcasting the moment according to start broadcasting moment and the delay inequality between client and server of server.
In step 1015b, alternatively, the client moment T1 that starts broadcasting can calculate according to formula T1=T2+ △ T.Wherein, T2 is that server starts broadcasting the moment, and obtain by above-mentioned steps 1013b, △ T is the delay inequality between client and server, obtains by above-mentioned steps 1014b.
It should be noted that, also comprise after step 1013b:
Step 1016b: obtain the playing duration corresponding with server feature code from fixing multimedia content library, using the playing duration as fixing multimedia content.
In step 1016b, the playing duration corresponding to the current fixing multimedia content starting to play of client can also be obtained based on fixing multimedia content library, in follow-up flow process, client finish time be calculated.
It should be noted that, the situation of carrying out step 1016b in figure 3 after execution of step 1015b more only plays exemplary effect, in the present embodiment, only need to meet step 1016b to perform after step 1013, step 1016b and the order between step 1014b and step 1015b are not restricted.
It should be noted that, with the technical scheme of above-mentioned steps 1011a ~ step 1013a unlike, the remote media play signal received by client in step 1011b ~ step 1015b, be stored in the fixing multimedia content library of server and the delay inequality between client and server, also can get server and start broadcasting the moment.
It should be noted that, additive method can also be adopted in the application to start broadcasting the moment to the client obtaining fixing multimedia content and start when playing in client, illustrate no longer one by one herein.Those skilled in the art should know, and be applicable to start broadcasting in the client client started when playing the method in moment to obtain fixing multimedia content in the application, also should belong to the protection range of the application for other.
Step 102: calculate the client finish time that fixing multimedia content terminates when playing in client according to start broadcasting moment and the playing duration of fixing multimedia content that gets in advance of client.
In a step 102, the client finish time T1 ' that fixing multimedia content terminates when playing in client can be calculated accurately, wherein T1 '=T1+t by the client got in the step 101 moment T1 and the playing duration t of fixing multimedia content that gets in advance that starts broadcasting.
Step 103: send to client within the time period that client started broadcasting between the moment to client finish time and fix the pushed information that multimedia content matches.
Above-mentioned steps 101 and step 102 to start broadcasting moment T1 and client finish time T1 ' owing to can get client accurately, as long as therefore meet the time period sent to client and fix the pushed information that multimedia content matches in step 103 to be positioned at client and to start broadcasting between moment T1 to client finish time T1 ', thus make the time of transmission pushed information and client actual play fix the time synchronized of multimedia content, and then the pushed information of client displaying and the unmatched problem of content of client actual play in prior art can be solved.
It should be added that, start broadcasting the moment to obtain client when adopting the flow process shown in Fig. 3 in the present embodiment, and the delay inequality got in step 1014b between client and server is when being negative value (the remote media play signal that client receives is prior to server), is positioned at server starts broadcasting between moment T2 to client finish time T1 ' as long as then meet the time period sending and fix the pushed information that multimedia content matches to client in step 103.
In the present embodiment, alternatively, also comprised before step 103:
Step 103a: generate and the pushed information of fixing multimedia content and matching according to the fixing multimedia content pushed information coupling storehouse pre-set.
Wherein, storing in fixing multimedia content pushed information coupling storehouse can several fixing multimedia contents of implementation information Push Service and each fixing multimedia content pushed information of mating.
