Aforesaid client can be with just not asking the client of synchronized playback to carry out synchronous playing to other in the video source active push of playback.
Aforesaid client does not ask the synchronous playing request of the sending general of the client of synchronized playback just to be pushed to the client that other do not ask synchronized playback in the video source of playback according to other.
A kind of audio video synchronization back method may further comprise the steps:
Step 1, client are sent the synchronized playback request to the Movie House server, and selection needs the video recording resource of synchronized playback;
After step 2, Movie House server are received the synchronized playback request; Judge the current idle data channel that is used to transmit video source that whether has; If idle data channel is arranged; And for the selected corresponding data channel of synchronized playback request and the passage feedback signal is set for idle data channel signal is arranged, to carry out fluidisation be video source and send to client through selected corresponding data channel with the video recording resource, as if there not being the idle data passage; It is no idle data channel signal that channel signal then is set, and transmits the passage feedback signal to client;
Step 3, client receive Movie House server channels feedback signal, if the passage feedback signal is no idle channel signal, then stop the playback flow process; If the passage feedback signal is for there being the idle channel signal, then through data channel receiver, video source selected in the step 2, and carry out playback, get into step 4;
Step 4, the Movie House server resource of will recording a video converts video source to, and through selected data channel video source is sent to client.
A kind of audio video synchronization back method comprises that also the client active push just do not asking the step of the client of synchronized playback to other in the video source of synchronized playback.
A kind of audio video synchronization back method comprises that also client just is pushed to the step that other do not ask the client of synchronized playback in the video source of playback according to other synchronous playing request generals that do not ask the client of synchronized playback to be sent.
The present invention compared with prior art has the following advantages:
1, synchronized playback only needs an originating end, and certain passage of other clients of message informing is carrying out playback, and other clients just can be carried out synchronized playback by this passage of program request, and are simple to operate.
2, whole flow process has controllability, and the synchronized playback promoter can control the situation (F.F., slow-motion, time-out etc.) of whole synchronized playback.
3, only need a synchronized playback server and several client just can realize synchronized playback, practice thrift the cost of realizing synchronized playback greatly.
