And method.
Background technique
One user usually possesses muti-piece screen, such as TV (television set), mobile terminal (smart phone or plate electricity
Brain, iOS android operating system), PC (computer) etc..In a terminal, realize that video playing breakpoint management compares
Generally.
Such as: application No. is a kind of 201110144970.5, entitled " audio/video continuous play seamless switching systems
And method " Chinese invention patent disclose a kind of audio/video continuous play seamless switching system and method, comprising: multipath pipe
Module, data buffering module, data outputting module and at least two document storage servers are managed, are filled after system initialization
Operation when encountering the abnormal conditions such as network failure or read error in audio-video document playing process for TV, carries out
Bumpless transfer operation achievees the purpose that system is continuously broadcasted, and avoids manual operation bring triviality and uncertainty.
For another example application No. is 201510150780.2, entitled " seamless handover methods of live video stream "
Chinese invention patent application discloses a kind of seamless handover method of live video stream, comprising: video flowing acquisition terminal receives user
After the specification switching request of terminal, original encoding device example is kept to continue to run, and starts a new encoder example；It will newly regard again
Frequency stream carries out frame number synchronization with original video stream；Then in new video stream select a key frame, and since the key frame to
User terminal transmits new video stream, and original video stream terminates after having transmitted the previous frame data of the key frame, and the frame of the key frame
Number and original video stream the last one key frame frame number between spacing be greater than new video stream GOP length 1/2；Then it closes again
Close original encoding device example.Front-end collection compression device of this method suitable for RTP Transport System for Real-time.
The above-mentioned prior art is all based on the breakpoint in same terminal and plays seamless switching.In reality, user possesses more
Media information number of terminals amount and type are gradually enriched, but due to the access network of multiple terminal, the difference of information acquisition platform, are made
The situation that independent of one another, resource cannot be shared at plurality of devices.With the continuous propulsion of integration of three networks process, how to using

Message signaling completes control of the user terminal to another user terminal, i.e., described first video playing terminal controls correlation
System order is sent to the central server, and the central server completes to be suitble to the parsing and generation of related protocol described the
The control signaling of two video playing terminals parsing, and control signaling is sent to second video playing terminal, complete film
Broadcasting on multiple user terminals, and the nothing of another user terminal is seamlessly switched in playing process by a user terminal
Interruption plays and control.
Preferable in the embodiment of the present invention, the central server can both receive the login letter of the same account of same user
Breath, the currently used user terminal of the user is judged according to the Account Logon information of the user, and according to the screens switch
The newest video file not finished of first video playing terminal 101 is being switched to the user currently just automatically by information
In second video playing terminal of login；Can also receive between different user screens switch request, different user it
Between can by plusing good friend, by it in first video playing terminal 101 video file being played on switch to it is described
Second video playing terminal 103, to realize the video sharing function between good friend.
It is preferable in the embodiment of the present invention, further include video server, the video server respectively with the resolver,
First video playing terminal 101 and second video playing terminal 103 connection, it is suitable for all into system
Media content is handled, and the relative index file for being directed to different media formats is generated.Specifically, the video server is to institute
There is the media content into system to be handled, completes the secondary volume transcoding and encapsulation process of streaming media content, and generate needle
To the relative index file (XML format ADI document) of different media formats.
It is preferable in the embodiment of the present invention, after first video playing terminal 101 receives video switching command, currently
Video can continue to play at the first video playing terminal 101, can also suspend current video in the first video playing terminal
101 broadcasting.
If after the first video playing terminal 101 receives video switching command, current video is at the first video playing end
It holds and continues to play at 101, then after the first video playing terminal 101 receives video switching command, the central server can be remembered
Playback progress of the current video at the first video playing terminal 101 when it receives video switching command is recorded, and according to record
Playback progress generate playback progress information；The current video that first video playing terminal 101 plays is switched into the second video
When playback terminal 103 plays, broadcasting of the current video at the first video playing terminal 101 is not influenced.
If after the first video playing terminal 101 receives video switching command, current video is at the first video playing end
It holds to suspend at 101 and play, then playback progress of the central server records current video at pause, and according to current video
