Embodiment
In order to solve in the prior art, the user is when network requests IPTV programme televised live, and network side can't determine that the user asks the programme televised live of watching, thus the problem that can't control the programme televised live of user request.The embodiment of the invention provides a kind of methods, devices and systems that the IPTV programme televised live is controlled.
In following embodiment, initiate request by the live broadcast service apparatus for initiating, and control according to this request programme televised live that request is watched to described live broadcast service apparatus for initiating by the live broadcast service control device to programme televised live.
As shown in Figure 1, the method that the IPTV programme televised live is controlled that the embodiment of the invention provides comprises:
Step 101 receives the programme televised live request message that the live broadcast service apparatus for initiating sends, and in the present embodiment, described programme televised live request message can be Session initiation Protocol invitation message (SIP invite).
Step 102 according to the view content indication information that described programme televised live request message carries, is determined the programme televised live that request is watched.
In the present embodiment, described view content indication information can be the programme televised live indication information, also can be programme televised live indication information and channel identication.
Wherein, described programme televised live indication information can be program identification information, as the BCprogramID of appointment in the TISPAN standard; Perhaps time period identification information is as time started and concluding time identification information; Perhaps the program key word identification information is Liang Chaowei etc. as protagonist.In the use of reality, described programme televised live indication information can also be other relevant information of programme televised live with the request of live broadcast service apparatus for initiating, perhaps be the combination in any of above-mentioned several identification informations, all possible situation do not given unnecessary details one by one herein.Described channel identication can be the BCserviceID of appointment in the TISPAN standard, certainly, also can be other signs relevant with channel.
When described programme televised live indication information is time period during identification information, this time period identification information can only comprise the concluding time identification information, and at this moment, it is the time started that network side can be given tacit consent to the time that receives described programme televised live request message; Described time period identification information also can only comprise the time started identification information, and at this moment, network side can be provided with Default End Time according to presetting strategy, as being provided with after the time started 1 hour for the concluding time etc.
Described view content indication information can be carried at the header field of described programme televised live request message, and perhaps parameter field is perhaps in the message body.For example: as follows, described view content indication information can with Session Description Protocol (Service Discovery Protocol, the form of a SDP) capable (session attribute is capable) agreement is carried in the message body of SIP invite message:
a＝bc_service：BCServiceId
a＝bc_program：BCprogramId
Or
a＝bc_service：BCServiceId；BCprogramId；
Perhaps, as follows, described view content indication information can be carried in the message body of SIP invite message with the XML form:
Figure GSB00000455077200061
In the present embodiment, when described view content indication information comprised programme televised live indication information and channel identication, described step 102 comprised: according to described programme televised live indication information and channel identication, determine the programme televised live that request is watched;
When described view content indication information comprised the programme televised live indication information, described step 102 comprised:
According to described programme televised live indication information, the channel identication at the programme televised live place that the request of obtaining is watched; In the present embodiment, the live broadcast service control device can obtain the channel identication of the programme televised live that described request watches from self canned data; Also can be from other network entities, as service selection functional (Service Selection Function, SSF) (Content Profile Service Function, CPSF) entity obtain the channel identication of the programme televised live that described request watches for entity or content-data function;
According to described programme televised live indication information and channel identication, determine the programme televised live that described request is watched.
Step 103 is watched control to the programme televised live that described request is watched.
In another embodiment provided by the invention, as shown in Figure 2, after step 102 as shown in Figure 1, can also comprise before 103:
Step 102a judges whether the programme televised live that described request is watched arrives reproduction time.
Then step 103 as shown in Figure 1 can be specially 103a as shown in Figure 2 in the present embodiment, watches control according to the programme televised live that the judged result of step 102a is watched described request.
