Specific embodiment
Below by drawings and Examples, technical scheme is described in further detail.
The present invention is in same LAN under multi-screen interaction scene according to multiple terminals, is proposed
A kind of video switching method based on multi-screen interactive.
Fig. 1 is a kind of video switching method flow chart based on multi-screen interactive provided in an embodiment of the present invention.
As shown in figure 1, the method is comprised the following steps：
Step 101, controls service end according to multi-screen interactive protocol search and source terminal in same LAN
Target terminal, and zapping requests are sent to the source terminal；
Specifically, control service end and be based on multi-screen interactive agreement, search is in same LAN with source terminal
Interior has the terminal of connection as target terminal, and initiates zapping requests to source terminal, and safeguards source
Annexation between terminal and target terminal.
Step 102, source terminal is set up with target terminal according to the information carried in the zapping requests and is connected
Connect；
Specifically, source terminal starts local player, and video, side caching are played in the way of transmitting as a stream
Side is played, and records the relevant informations such as the video address of currently playing video.Come when source terminal is received
After the handover request that control service end from same LAN is sent, according to the target carried in the request
The information of terminal, to target terminal confirmation link information is sent.If target terminal receives the confirmation,
A confirmation is then beamed back, so far, source terminal and target terminal formally set up connection.
Step 103, source terminal sends the stream medium data for having cached and video control information to target end
End；
Specifically, source terminal will be locally buffered, but the stream medium data not yet played, and record
Currently playing video control information be sent to target terminal, the control information includes currently playing video
Video address, receives play position during handover request, and the length letter of buffered good data
The information such as breath.
Step 104, target terminal plays the stream medium data for receiving, and is believed according to video control
Breath continues to send request of data to streaming media server.
Specifically, target terminal is received after the stream medium data that source terminal is sent, to the stream medium data
Peeled off.The data cached video ground sent according to source terminal for directly broadcasting, video control information
Location information, and the moment and data cached length determination broadcasting moment of switching are initiated, and from this moment
Continue to streaming media server request data, realize the complete broadcasting of video.
Additionally, source terminal send it is buffered, but not yet play stream medium data when, be according to institute
The video playback positional information of carrying searches the picture group at the position, then from first frame of this picture group
Start to provide video data to target terminal.
In one example, as shown in Fig. 2 source terminal, target terminal, control service end are based on multi-screen
Interaction protocol, establishes a connection in same LAN, and safeguards source terminal and mesh by control service end
Annexation between mark terminal.Source terminal starts local player, is played in the way of transmitting as a stream and is regarded
Frequently, play in caching, and record the relevant informations such as the video address of currently playing video.Work as target
Terminal initiate play switching request when, the request is processed by control service end, and be transmitted to
Target terminal keeps the source terminal of connection status.When source terminal receives the target in same LAN
After the handover request that terminal is sent, the broadcasting moment now is recorded, locally buffered will not yet be played
Stream medium data be sent to target terminal, and by the video address of the currently playing video of record, receive
To play position during handover request, and the other information such as the length information of buffered good data is same
When send.Target terminal is received after the data that source terminal is sent, and the information for receiving is peeled off, for caching
Data, can directly play, for control information, the video address information to send according to source terminal,
And the moment and data cached length determination broadcasting moment of switching are initiated, and continue to stream from this moment
Media server request data, is realized that video is complete, is quickly played with this.
Fig. 3 is a kind of video switching system schematic diagram based on multi-screen interactive provided in an embodiment of the present invention.
As shown in figure 3, the system includes：Control service end 201, source terminal 202 and target terminal 203.
Target terminal 203 is attached with source terminal 202, control service end 201 by multi-screen interactive agreement,
And three is in same LAN.Control service end 201 be based on multi-screen interactive agreement, for search with
Source terminal 202 has the terminal of connection as target terminal 203 in same LAN, and to source
Terminal 202 initiates zapping requests, and safeguards annexation therebetween；Source terminal 202
Regard for receiving the zapping requests that control service end 201 is sent, and providing for target terminal 203
Be taken in small doses at short intervals business；Target terminal 203 is used to receive the video data that source terminal 202 is sent, and continues to stream
The video data that media server request is not received, realizes the complete broadcasting of video.In an example
In (Fig. 3 is not indicated), control service end and source terminal or target terminal can be same equipment,
The invention is not limited in this regard.
