Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, the technical solution in the embodiment of the present application is carried out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall in the protection scope of this application.
Next, referring to Fig. 1, Fig. 1 is a kind of multimedia programming method flow diagram disclosed in the embodiment of the present application.
As shown in Figure 1, this method includes：
Step S100, it receives and cuts platform instruction, the platform of cutting is instructed comprising the channel information to be switched to；
Specifically, user cuts platform to set-top box input by other manners such as remote controlers and instructs, and use is contained in the instruction
The information of the family channel to be switched to.
Step S110, the corresponding media stream data of the channel information is asked to server, while in a manner of http with dvb
Mode obtains the corresponding media stream data of the channel information from the media stream data that server is broadcast；
Specifically, for dvb modes, can not actively send and ask to server, but from server constantly to
Each terminal sends media stream data, and each terminal can obtain and channel after receiving and cutting platform instruction from media stream data
The corresponding media stream data of information.
Step S120, when receiving the media stream data that http modes are asked, program broadcasting is carried out in a manner of http, together
When, the media stream data obtained for dvb modes descrambles；
Since the media stream data that http modes are asked does not need to descramble, understood after request to data directly with http
Mode carries out program broadcasting.And since the media stream data that dvb modes are asked is descrambled, in a manner of http into
While row program plays, scramble process is carried out to the media stream data that dvb modes are asked.Descrambling generally requires 1-3 seconds or so
Time.
Step S130, it when detecting that descrambling is completed, controls from http broadcast modes and is switched to dvb broadcast modes.
After descrambling successfully completes, control from http broadcast modes and be switched to dvb broadcast modes.Pass through two kinds of broadcast modes
Switching, realize the promotion for cutting platform rate.
Multimedia programming method provided by the embodiments of the present application is being received comprising the channel information to be switched to
When cutting platform instruction, the corresponding media stream data of the channel information is asked to server in a manner of http, at the same in a manner of dvb from
The corresponding media stream data of the channel information is obtained in the media stream data that server is broadcast, and is receiving http modes
During the media stream data of request, program broadcasting is carried out directly in a manner of http, meanwhile, the media stream number obtained for dvb modes
According to scramble process is carried out, after the completion of descrambling is detected, control from http broadcast modes and be switched to dvb broadcast modes.The application
It does not need to carry out the advantage of descrambling operation using http broadcast modes, program is carried out using http modes in dvb descrambling procedures
It plays, and switching is switched to dvb modes and plays out again after the completion of descrambling, improves and cuts platform speed.
Referring to Fig. 2, Fig. 2 is another multimedia programming method flow diagram provided by the embodiments of the present application.
As shown in Fig. 2, this method includes：
Step S200, it receives and cuts platform instruction, the platform of cutting is instructed comprising the channel information to be switched to；
Specifically, user cuts platform to set-top box input by other manners such as remote controlers and instructs, and use is contained in the instruction
The information of the family channel to be switched to.
Step S210, the corresponding media stream data of the channel information is asked to server, while in a manner of http with dvb
Mode obtains the corresponding media stream data of the channel information from the media stream data that server is broadcast；
Step S220, when receiving the media stream data that http modes are asked, program broadcasting is carried out in a manner of http, together
When, the media stream data obtained for dvb modes descrambles；
Since the media stream data that http modes are asked does not need to descramble, understood after request to data directly with http
Mode carries out program broadcasting.And since the media stream data that dvb modes are asked is descrambled, in a manner of http into
While row program plays, scramble process is carried out to the media stream data that dvb modes are asked.
Step S230, it when detecting that descrambling is completed, controls from http broadcast modes and is switched to dvb broadcast modes；
After descrambling successfully completes, control from http broadcast modes and be switched to dvb broadcast modes.Pass through two kinds of broadcast modes
Switching, realize the promotion for cutting platform rate.
Step S240, when detecting descrambling failure, stop playing program in a manner of http, and user is prompted not have this
The play right of program.
Specifically, if user does not play the permission of the program of requested channel, set-top box will be unable to successfully right
Media stream data is descrambled, therefore dvb broadcast modes do not allow user to watch the program of the channel.Therefore, control stop with
Http modes play program.Meanwhile user can be prompted not have the permission for watching this program.
Through this embodiment it is found that in the case where whether uncertain user has and watch this channel program, first with http
Mode plays program to user, if descrambling successfully, is switched to dvb modes and continues to play, if descrambling failed namely user not
Have the permission for watching this channel program, then stopping is controlled to play program in a manner of http.Since descrambling is taken on a 1-3 seconds left sides
The right side, so even user does not have the permission for watching this channel program, the application has also only provided a user 1-3 seconds or so
Program video does not interfere with the interests of multimedia supplier.
Referring next to Fig. 3, Fig. 3 is the method stream that a kind of http modes disclosed in the embodiment of the present application carry out program broadcasting
Cheng Tu.
As shown in figure 3, this method includes：
Step S300, the media stream data asked the http modes parses；
Step S310, according to preset audio/video decoding form, the media stream data after parsing is decoded；
Step S320, according to preset audio and video playing parameter, decoded media stream data is played out.
By above-mentioned flow diagram, http broadcast modes are that there is no the processes descrambled to media stream data.And
Dvb broadcast modes will increase the process of a descrambling on the basis of the above.
