To combine accompanying drawing to specify embodiment of the present invention below.
Referring to Fig. 1, the figure shows a kind of method that realizes the control of segmentation playing programs of the embodiment of the invention, said segmentation program comprises one or more segmentation, the method comprising the steps of:
Step S101: the duration that server is play as required is each the segmented configuration playing duration Control Parameter in the segmentation program, and said playing duration Control Parameter comprises to be play zero-time and/or broadcast concluding time;
Step S102: client is carried out Play Control according to the playing duration Control Parameter of each segmentation in the said segmentation program to said each segmentation when playing the segmentation program.
The present invention is in order to realize the Play Control to the segmentation program; Increased the playing duration controlled function; The duration of promptly playing according to actual needs; Be each the segmented configuration playing duration Control Parameter in the segmentation program neatly at server end, thereby make client-side to control reproduction time and play content effectively according to the playing duration Control Parameter of said configuration.Especially for advertisement insertion; Intercutting under the uncertain situation of scene, that adopts that such scheme of the present invention can adjust advertisement flexibly intercuts duration and play content, makes the user watch program to link up; Improved user's experience; Need not adjust the making of segmentation because of different scene, realize that cost is low, have very big market value.
Step S101 is when concrete the realization, and server can be each the segmented configuration playing duration Control Parameter in each segmentation program through starting corresponding process or service.
Among the above-mentioned steps S101, said server can be expanded MPD, and the playing duration Control Parameter of each segmentation in the segmentation program is carried among the MPD of said segmentation program.When the said MPD of said client downloads plays the segmentation program, can from said MPD, get access to the playing duration Control Parameter of each segmentation in the said segmentation program easily.
Among the above-mentioned steps S101, said server is that segmented configuration playing duration Control Parameter can adopt following any one mode to realize:
First mode: the broadcast zero-time of confirming segmentation; Calculate the broadcast zero-time and the duration sum that needs said segmentation to play of said segmentation, to obtain the broadcast concluding time of said segmentation; Play start time according to said segmentation disposes the playing duration Control Parameter of said segmentation with the broadcast concluding time.
Second mode: the broadcast concluding time of confirming segmentation; The broadcast concluding time of calculating said segmentation is poor with the duration that needs said segmentation to play, to obtain the play start time of said segmentation; Play start time according to said segmentation disposes the playing duration Control Parameter of said segmentation with the broadcast concluding time.
Wherein, Said server according to the play start time of segmentation with play the concluding time when disposing the playing duration Control Parameter of said segmentation, can adopt this mode: the play start time that the playing duration Control Parameter that disposes said segmentation comprises said segmentation with play the bundle time.Correspondingly, when said client is carried out Play Control according to said playing duration Control Parameter to segmentation, will control said segmentation and begin to play, and stop to play to the said broadcast concluding time from said play start time.
Preferably, the present invention is directed to 2 kinds of special sights, i.e. beginning from segmentation begins to play, and the ending that plays to segmentation, but the configuration mode of following clipped parameter also is provided:
Said server is when the beginning position of the corresponding said segmentation of the broadcast zero-time of confirming segmentation, and the playing duration Control Parameter that disposes said segmentation only comprises the broadcast concluding time of said segmentation.That is,, can omit the play start time of configuration segmentation to the sight that the beginning from segmentation begins to play.Correspondingly, said client only comprises broadcast during the concluding time in the playing duration Control Parameter of segmentation, will control said segmentation and start anew to play, and stops to play to the said broadcast concluding time.
Said server is when the end position of corresponding said segmentation of the broadcast concluding time of confirming segmentation, and the playing duration Control Parameter that disposes said segmentation only comprises the play start time of said segmentation.That is,, can omit the broadcast concluding time of configuration segmentation to the sight of the ending that plays to segmentation.Correspondingly, when said client only comprises play start time in the playing duration Control Parameter of segmentation, control said segmentation and begin to play from said play start time, extremely the end position of said segmentation stops to play.
