Embodiment
The embodiment of the present invention provides control method for playing back and equipment, by send the message that carries Play Control information to terminal, make terminal to carry out Play Control according to described Play Control information, referring to accompanying drawing, be elaborated by specific embodiment.
Server can send message to terminal entering advertisement constantly or withdrawing from advertisement constantly, is entering advertisement constantly, and the Play Control information that described session control message is carried is specially forbids F.F., perhaps for forbidding F.F. and location; Withdrawing from advertisement constantly, described Play Control information is specially the permission F.F., perhaps for allowing F.F. and location, makes terminal carry out Play Control according to described Play Control information.
For example, media server can be directly from media file or from the broadcast strategy server, perhaps other approach obtain strategy and the information of Play Control, thereby can obtain the moment that the Play Control state need to change, and send message in the described moment that needs to change.Such as, before broadcast advertisement, media server is carried out some operation by carry Play Control information indicating terminal content blocking user thereafter in session control message, for example forbids F.F., rewind down and location.And when advertisement finished, media server wished again to remove to the forbidding of these operations, therefore can carry Play Control information and be used to indicate terminal content thereafter and allow the user to carry out F.F., rewind down and positioning action in new session control message.Terminal can be carried out corresponding Play Control after obtaining these Play Control information.Below be elaborated by specific embodiment:
With reference to Fig. 1, be embodiment of the present invention control method for playing back embodiment one flow chart, by expanding existing real-time stream media protocol (RTSP, Real-Time Streaming Protocol) message is transmitted Play Control information, for example, define the announce/set_parameter message that is mail to end side by media server in RTSP, can expand the x-Notice header field to this message, and define the conditional code of some expression Play Control information, for example:
1105: " Fast_forword Disable " forbids F.F.;
1106: " Fast_forword Enable " allows F.F.;
1107: " Rewind Disable " forbids rewind down;
1108: " Rewind Enable " allows rewind down;
1109: " Pause Disable " forbids suspending;
1110: " Pause Enable " allows to suspend;
1111: " Goto Disable " forbids positioning playing;
1112: " Goto Enable " allows positioning playing;
Below be elaborated by concrete steps:
S11, media server obtain the moment that the Play Control state need to change;
For example, media server can obtain the moment that the Play Control state need to change from media file or Play Control strategic server or other approach, and as being about to broadcast advertisement, advertisement closes to an end.
S12, media server send the announce(notice in the moment that the Play Control state need to change) message, carry Play Control information in described announce message;
For example, entering advertisement constantly, media server is by sending announce message, and the content that in message, the carrier state code identifies does not thereafter allow forwarding operation:
S->C:ANNOUNCE?rtsp://foo.com/bar.avi/streamid=0?RTSP/2.0
CSeq:1
Session:12345678
x-Notice:1105?Fast_forword?Disable
Can find out, wherein carry conditional code 1105 in the header field x-Notice of expansion: " Fast_forword Disable " illustrates content blocking forwarding operation thereafter.
After receiving, terminal can return to a response message:
C->S:RTSP/2.0?200?OK
CSeq:1
Session:12345678
The received 200OK response message of terminal represents correctly to receive announce message.
And withdrawing from advertisement constantly, and media server is by sending new announce message, and in message, carrier state code indication content thereafter allows forwarding operation:
S->C:ANNOUNCE?rtsp://foo.com/bar.avi/streamid=0?RTSP/2.0
CSeq:2
Session:12345678
x-Notice:1106?Fast_forword?Enable
Can find out, wherein carry conditional code 1106 in the header field x-Notice of expansion, the permission forwarding operation be described, i.e. thereafter content recovery forwarding operation.
Return to a response message after terminal is received, expression correctly receives:
C->S:RTSP/2.0?200?OK
CSeq:2
Session:12345678
Be understandable that, also can adopt other sign to represent different Play Control information.In addition, enter advertisement constantly, also can forbid simultaneously the fast forwarding and fast rewinding operation.Correspondingly, play the finish time when advertisement, allow to carry out the fast forwarding and fast rewinding operation.If player has the positioning control function, entering advertisement constantly, also can forbid simultaneously positioning action.Also can entering advertisement and constantly forbid user's all operations, for simplicity, also can define corresponding conditional code.
S13, terminal according to Play Control information entrained in message, are carried out corresponding Play Control after receiving announce message.
For example, carry conditional code 1105 in expansion header field x-Notice by received RTSP message: " Fast_forword Disable ", thereafter content blocking forwarding operation is described, described terminal forbids that the user carries out forwarding operation after receiving described RTSP message; If know in the expansion header field x-Notice of RTSP message and carry 1105: " Fast_forword Disable " and conditional code 1111: " Goto Disable ", after described terminal receives described message, forbid that the user carries out F.F. and positioning action.
When carrying out above-mentioned Play Control, Play Control state that can also terminal is current shows, to give user friendly prompting, for example, when forbidding that the user carries out certain operation, with the button ashing of this operational correspondence, and when allowing the user to carry out certain operation, with the button brightening of this operational correspondence.
In the present embodiment, by sending message to terminal, carry Play Control information in message, terminal is carried out Play Control according to described Play Control information, thereby realize carrying out Play Control when breaking for commercialsy, the method for visible this Play Control can not produce any impact to the program of playing, and does not need to revise program source, only need to be by the simple transmission of messages mode Play Control that just can effectively break for commercialsy, cost is lower.Simultaneously, can avoid user's invalidation request, and then can avoid the network and the media server end redundant operation that cause because of user's invalidation request, therefore can save network transmission resource, improve media server processes efficient.
Can also adopt other message to transmit Play Control information, with reference to Fig. 2, be embodiment of the present invention control method for playing back embodiment two flow charts, expand existing conversation initialized protocol (SIP, Session Initiation Protocol) message, carry Play Control information by the INFO in SIP or MESSAGE message, can expand a kind of type of message application/controlinfo this moment, and define some control parameters, and for example, definition: 0: forbid corresponding operating; 1: allow corresponding operating.Below describe by idiographic flow:
S21, media server obtain the moment that the Play Control state need to change;
For example, media server can obtain the moment that the Play Control state need to change from media file or Play Control strategic server or other approach, and as being about to broadcast advertisement constantly, advertisement closes to an end constantly.
S22, media server send INFO or MESSAGE message in the moment that the Play Control state need to change to terminal, carry Play Control information in described INFO or MESSAGE message;
For example, entering advertisement constantly, media server passes to terminal by the IPTV controller with INFO or MESSAGE message, carries Play Control information in described INFO or MESSAGE message, is used for identifying follow-up content blocking fast forwarding and fast rewinding operation:
Terminal is received and is returned to response after message:
SIP/2.0?200?OK
