Abstract
This invention belongs to the information issue technique field. It is a kind of arrangement method of information issue priority in broadcast video program system. For the limited channel capacity, when there is a lot of information to send, they must comply with some sequence. This invention provides a kind of information issue priority arrangement method evaluated by the importance of information, the time to require, the information content, and capacity. This method balances the efficiency and fair, and uses the channel resource effectively, improves the information issuing efficiency.
Description
Technical field
The invention belongs to the information publishing technology field, be specifically related to the decision-making technique that priority is ranked when big capacity information need send in a kind of broadcast video program system.
Technical background
In system according to user's program request situation broadcast video program, because user's interest is varied, the program that possible program request is different, a large amount of predetermined informations may be collected in the broadcasting center, and the information broadcast how fast and efficiently user to be needed is gone out and is become a problem.
Although the broadcasting center may have than higher transmission bandwidth, for example the data of per second 32 megabits can send, and the capacity of video frequency program is very huge, and common one hour video needs the capacity of about 1 gigabyte.We suppose that one hour video needs 1 gigabyte, and the bandwidth of broadcast channel is 32 MBPSs, and so such broadcast channel can be sent 300 hours video frequency program every day.Look that this numerical value is very big, but for user's great demand, remain not enough.
User's program request may be distributed in every field, but according to 80/20 principle (i.e. 80% user care 20% content), the IP Information On Demand of a large number of users always concentrates on the minority popular program.For example, a New cinema enters system, and the people that may pay close attention to is a lot, and everybody wants to have a look at; Perhaps some popular media events are as the war in Iraq, and people extremely are concerned about its progress, wish in time to obtain new information.Popular information like this should obtain than higher priority.Should take into account simultaneously some predetermined fewer information, these information can be sent within a certain fixing longest term, for example require in 3 days, to give the user with the information of consumer premise, all information that will send must be ranked according to certain rule or method, send implementation efficiency and fair balance one by one.
Therefore, it is very important to seek a kind of method of rational evaluation information priority level.
Summary of the invention
At the problems referred to above, the invention provides a kind of aligning method of information issue priority.Be required the time that sends, the capacity of information itself, the priority of the aggregation of data evaluation information issue arrangement of this three aspect according to the temperature of information (be program request number what), information.The people who that is to say program request is many more, and priority is high more; The time of program request, more early priority was high more; Video frequency program is short more, and priority is high more.And, also upgrade the priority arrangement order simultaneously because the data of collecting are brought in constant renewal in.In case the broadcast transmission channel idle is about to the highest information of current priority and sends, simultaneously the priority of this information is reduced to minimumly, allow next information be ready for sending.
The inventive method has taken into full account the equilibrium of performance and fairness, can effectively utilize information resources, improves the information transmitting efficiency.
Description of drawings
Fig. 1 has provided the flow process of priority of disposing order.
Fig. 2 has provided the change situation of priority list.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in detail.
As shown in Figure 1, priority of disposing order adopts following steps:
1, collects user's IP Information On Demand.
2, IP Information On Demand is corresponded on each video frequency program.Each video frequency program all has a record in other words, has write down the number of the current program request of this program, the time of program request the earliest and the length of this program.
3, arrange the priority of video frequency program, press following principle:
(1) people of program request is many more, and priority is high more;
The number of program request is many more, illustrates that this video frequency program is that a lot of people likes, should send it to the user who needs it as early as possible, reduces period of reservation of number.
(2) more early priority is high more the time of program request;
Although some video frequency program program request is fewer in number, also should within a period of time, video frequency program be sent to the user, for example three a days time limit the highest here will be set, in three days, must send to the user to the program of consumer premise.Make the user after three days, must watch video frequency program, can unrestrictedly not wait and stay.
(3) video frequency program is short more, and priority is high more.
Because broadcast channel has only one, a lot of informational needs send, and some video frequency program may be very big, and for example a TV play has tens collection.The method that we adopt is TV play to be divided into one collect transmission.Although most of users can subscribe to whole TV play, that is to say that the priority of each collection of this TV play is identical.But disposable whole TV play is sent out possibly takes a long time, other video frequency program just must be waited for, if user's download 40 collection TV play may have little time to see quickly at all, so for this very long video frequency program, be divided into several, block-by-block sends, and certain interval of time between piece and the piece allows short program intert in the centre and sends.For example the serial with 40 collection is divided into 10, and every 4 collection after reaching the broadcasting condition according to preceding 2 principle priority arrangement, is play one every day, and other times are broadcast by other video frequency programs.
According to mentioned above principle, can quantitatively calculate the priority of each video frequency program.Can calculate with reference to following formula:
Priority=A * program request number+B * program request time-C * program piecemeal sequence number
Wherein: A, B, C are adjustment factors, can set according to different real systems.For example, system's regulation must send to the user with the program of user's program request in three days, and the B coefficient of She Dinging must make this coefficient and the product of three day time reach limit priority so.And for example, the length of each normal video program of default is 45 minutes (i.e. the length of a collection TV play), wants the piecemeal transmission greater than 45 minutes video frequency program, and each piecemeal has a sequence number, transmits one by one according to the arrangement of sequence number.For length less than 45 minutes video frequency program then its piecemeal sequence number be 0, once send out, and can obtain higher priority.
1, dynamically updates playlist.
Because IP Information On Demand can be brought in constant renewal in, the priority of video frequency program is also brought in constant renewal in.
In case 2 broadcast transmission channel idle are about to the highest video frequency program of current priority and send.
3, reduce to the priority of this video frequency program minimum simultaneously.Program request number in the video frequency program that will send the exactly specifically record is made as 0, and the time of program request the earliest is made as sky, has come during calculating priority level last so automatically.Allow the highest video frequency program busy channel of next priority send.
Send so in turn, make full use of the resource of broadcast channel, make the video frequency program of consumer premise can be sent to the user there in time.
