In addition, while again establishing a communications link with described intelligent television end after described the first mobile device end exits continuous broadcast state, described intelligent terminal can receive the continuous broadcast state acquisition of information instruction that described the first mobile device end sends equally, afterwards current continuous broadcast state information is sent to described the first mobile device end.
S400, described the second mobile device termination are received described current continuous broadcast state information, and are utilized described current continuous broadcast state information to enter the continuous broadcast state of synchronizeing with described intelligent television end.
Wherein, current continuous broadcast state information can comprise index in playlist, described playlist, play breakpoint etc.
The the first mobile device end reentering after exiting also can utilize intelligent television end passback current continuous broadcast state information completely recover current continuous broadcast state.
When described the first mobile device end or the second mobile device end enter the continuous broadcast state of synchronizeing with described intelligent television end, by described the first mobile device end or the second mobile device end, can realize the control to described intelligent television end play content and broadcast state.Can play intelligent television, the control such as time-out, F.F., rewind down, other content play of selection playlist.
As shown in Figure 2 be that intelligent television end of the present invention is supported the theory diagram that a plurality of mobile clients are mutual simultaneously, the present invention be take intelligent television as control centre, the control logic of playing continuously and the continuously needed information of broadcasting are stored in intelligent television end, make to play and be no longer dependent on mobile device end (being mobile client) continuously, alleviated the burden of mobile client, mobile client A, B, C sets up communication with described intelligent television Play Control center by DLNA agreement and is connected, when mobile client need to be recovered continuous broadcast state, only need to control centre, to send instruction by the DLNA agreement of expansion, control centre receives after instruction, by DLNA agreement, the corresponding information of playing is continuously sent to mobile client again, client is used these information to recover continuous broadcast state according to the actual conditions of oneself again.
As shown in Figure 3 be the specific embodiment of the continuous player method of media in multi-screen interactive, its step is as follows.
S1, mobile client A are by DLNA discovering device.DLNA serves to the random ID of distribution of each equipment, standard agreement is called UUID, unique identification as each equipment, the process nature of device discovery is exactly the process of equipment UUID of searching by Web broadcast, after success discovering device, mobile client A and intelligent television are set up the communication channel of information interaction, and all communications are afterwards all to carry out based on UUID.
S2, data encapsulation.Mobile client a enters media center module, selects the media file object of broadcasting continuously, carries out the encapsulation of data.
S3, by DLNA agreement, transmit data.Mobile client A sends to intelligent television end the packet after encapsulation by DLNA agreement.
S4, reception packet, resolve.Intelligent television end receive the packet sending over, first need resolution data bag, resolve the data that obtain and deliver to Play Control center
S5, control centre.Preserve the data that receive at the Play Control center of intelligent television end, performs step afterwards S6.
S6, broadcasting continuously.Received data are used at Play Control center, control intelligent television and enter Automatic continuous broadcast state.Perform step afterwards S12.
S7, by DLNA discovering device.If mobile client A exit rear heavy enter or have new mobile client for example mobile client B need to enter continuous broadcast state, utilize method as described in step S1 to make mobile client set up communication with intelligent television end and be connected.
The instruction that continuous broadcast information is obtained in S8, discovery.Mobile client A or B send the instruction of continuous state acquisition of information to the control centre of intelligent television end by the service of DLNA protocol extension.
S9, control centre, the Play Control center of intelligent television end receives and obtains after instruction, collects the information of relevant current continuous broadcast state, performs step afterwards S10.
S10, by DLNA agreement, transmit data.Play Control center sends to mobile client A or B by DLNA agreement by the information of relevant current continuous broadcast state.
S11, according to the continuous broadcast state of data synchronous intelligent TV.Mobile client A or B obtain after the data of Play Control center passback for mobile client A or the complete current continuous broadcast state of recovery of B
S12, end.
Shown in Fig. 4 is that intelligent television end enters continuous broadcast state by the first mobile client and the second mobile client is obtained continuous broadcast state information and play synchronous process by intelligent television end, and this process steps is as follows:
T0, beginning.
T1, the first mobile client connecting TV.By DLNA agreement, setting up communication connects.
The video source that T2, the first mobile client utilization get generates playlist information.Described playlist information can generate according to above-mentioned table 1,2,3 form.
T3, transmission are play other list to TV.The controls such as the first mobile client enters state of a control, can send broadcast state information after intelligent television starts to play, and the first mobile client can be play TV, time-out, F.F., rewind down, other content of selection playlist are play.
T4, TV Automatic continuous are play.Intelligent television sends to broadcast state information the mobile client having connected, and responds the control command of mobile client simultaneously.
T5, TV stop playing, and preserve broadcast information.Intelligent television can be preserved current information before stopping playing.
T6, there is other mobile client to connect? if, have, perform step T7, if nothing performs step T11
T7, the second mobile client connecting TV.The second mobile client can be the first client of heavily entering after disconnecting or the new mobile client except the first mobile client.
T8, from TV, obtain associated video broadcast information.The content of information comprises that intelligent television stops the playlist before broadcasting, the index in playlist, the breakpoint of broadcasting etc.
T9, the second mobile client are carried out Play Control.The second mobile client enters state of a control, controls the continuous broadcast state of intelligent television.
T10, TV stop playing.TV stops playing, and does not have other clients to connect simultaneously, performs step T11.
T11, end.
The system that in a kind of multi-screen interactive as shown in Figure 5 and Figure 6, media are play continuously, wherein, described system comprises mobile device end 100 and intelligent television end 200, and described mobile device end comprises described the first mobile device end and the second mobile device end, and described mobile device end comprises:
