Whether monitoring unit 001, the Event Information Table for monitoring front end issue in real time updates.
Specifically, according to《DVB Chinese business information specification》Defined, EIT tables include 4 classes, respectively
For：Existing transport stream is current/successor information table EIT_PF_Actual, other transport streams are current/and successor information table
EIT_PF_Other, existing transport stream event time table information EIT_Schedule_Act-ual, other transport stream event times
Table information EIT_Schedule_Other.Wherein, the effect of each table is as shown in table 1：
Table 1
| Table name | Description |
| EIT_PF_Actual | The current time event and subsequent time event of all channels of current frequency |
| EIT_PF_Other | The current time event and subsequent time event of all channels of other frequencies |
| EIT_Schedule_Actual | Event in all channels one week of current frequency arranges timetable |
| EIT_Schedule_Other | Event in all channels one week of other frequencies arranges timetable |
Because operator can add EIT_PF_Actual and EIT_PF_ in front-end configuration EPG in each frequency
Other, so set top box is in zapping, current/successor advance notice just not only can quickly show but also will not make reception data volume
Burden it is too heavy.And the event schedules in all channels of other frequencies one week, data are included in EIT_Schedule_Other
Amount is huge, by top-set hardware condition is limited, if adding EIT_Schedule_Other in each frequency will have influence on
Set top box receives the efficiency of data, so operator is general only to add EIT_Schedule_Actual again in each frequency, without
Add EIT_Schedule_Other.
In consideration of it, no matter to ensure user in which frequency viewing program, the event subscription that can obtain any channel is carried
Show, the embodiment of the present invention only receives EIT_PF_Actual and EIT_PF_Other with the monitoring unit 001 to obtain event letter
Illustrated exemplified by breath.Whether the Event Information Table of the monitoring unit 001 monitoring front end issue in real time updates, the event letter
Ceasing table includes EIT_PF_Actual and EIT_PF_Other, and user can obtain the reference reservation event in current time+1 hour
Push, this can reach the effect of event subscription prompting, and monitoring unit 001 is monitored in real time, it can be ensured that do not miss use
The interesting event at family.
Simultaneously, however not excluded that with the reduction of the raising of set-top-box chip arithmetic speed, and internal memory and FLASH costs, machine
The efficiency that top box receives big data quantity can be improved, then operator can be configured in front-end configuration EPG information：In each frequency
Point all describes EIT_Schedule_Actual, only EIT_Sch-edule_Other is described in dominant frequency point, due to the two tables one
Week only updates once, so receiving number of times will be reduced, will not be described here.
Resolution unit 002, updates if monitoring that the Event Information Table is present for the monitoring unit 001, parses
The Event Information Table, obtains the primitive event information of each event.
Specifically, when the monitoring unit 001 monitors that EIT_PF_Actual and EIT_PF_Other update,
The resolution unit 002 receives and parses through the event information in EIT_PF_Actual and EIT_PF_Other, including parses short thing
Part descriptor and content descriptors, obtain the primitive event information of each event in EIT_PF_Actual and EIT_PF_Other.
The primitive event information includes：Event identifier event_id, play start time, playing duration, event title and event class
Not.
Sort out unit 003, for the primitive event information got according to the resolution unit 002, according to default
Each event is sorted out with degree and the validity event mark is distributed.
It is because of certain specifically, why to be sorted out to each event and distribute the validity event mark
The Digital ID of collection number, such as " the new Water Margin (12) ", " the new Water Margin (13) ", two are generally had in the event title of a little serials
The event title of person is different, but is approximate event in fact, and event subscription prompting can be carried out to set top box and causes wrong or tired
Disturb, it is necessary to which allocative efficiency event identifier valid_event_id is to distinguish event_id.
In addition, it is desirable to be sorted out in identical event category and distribute the validity event mark, because some things
Although part event title is identical, such as film《Blame sincere not faze》With love and marriage program《Blame sincere not faze》, but both do not represent it is identical
Event.
During sorting out and distributing valid_event_id, the classification unit 003 is according to the resolution unit 002
The primitive event information got, is compared between the event with identical event category to event title, to described
Each program that resolution unit 002 is obtained is sorted out and distributes valid_event_id, obtains the validity event database,
The corresponding primitive event information of each event and validity event mark are stored in the validity event database.
It is preferred that, in order to improve matching degree, for there is the event title of numeral and punctuation mark, only compare China and Britain therein
Chinese character.
Wherein, matching degree is a user preset for the numerical value for the similarity for representing two event titles.Default situations
Under, after the numeral and punctuation mark in filtering off event title are compared, matching degree is preset as 100%, that is, represents two
The Chinese and English character of event title is identical., can be with but if user is desired with fuzzy matching, it is not required that completely accurate
Matching degree is reduced, matching degree such as is revised as 75%, the unit 003 of sorting out will be by《The new Water Margin》With《The Water Margin》It is classified as
One class simultaneously distributes a valid_event_id.The value of matching degree can be repaiied in parameter setting page as shown in Figure 3
Change.
It is further alternative, as shown in Fig. 2 the memory module 00 specifically also includes：
Timing unit 004, for when the user starts watching the program, timing being carried out to the currently viewing event.Specifically
, the embodiment of the present invention provides a kind of correlating event viewing method for calculating probability based on conditional probability.Basic thought is：With
Family have viewed after some event, and typically all custom jumps to next event interested and watched, form a rating habit
It is used, and the broadcast time of event popular in the event time table of TV station's arrangement is also fixed.Based on this, it is assumed that user
It has viewed event e for the first timeiIt has viewed event e again afterwardsi+1, then in event eiEvent e is watched on the basis of having watched againi+1
The probability of generation is just P (ei+1|ei)=1；When next time, user have viewed event eiIt has viewed event e again afterwardsi+2, then can recognize
It is user in event eiEvent e typically can be habitually watched on the basis of having watchedi+1Or ei+2, i.e. event ei+1And ei+2Just
For event eiCorrelating event.So event e is have viewed again in useriAfterwards, set top box will be recommended according to record to user
eiCorrelating event：ei+1And ei+2.And for ei+1And ei+2The viewing probability of the two correlating events is, it is necessary to according to user preceding
E is accounted for the time that it is watched respectively in watching process twicei+1And ei+2Effective viewing weight of the total reproduction time of event and viewing
Number of times is to distribute weight, and effectively watching weight calculation formula is：
Wherein, tjRepresent the l times viewing e of useri+jTime, t 'jRepresent ei+jEvent
Total duration, k represents ei+jViewing number of times, 0≤l≤k.Wherein, the unit of time is minute, for the sight within one minute
See the time, tj=0, illustrate too short viewing time user may be only zapping or and be not concerned with the event, do not unite
Meter, in order to avoid produce junk data.
If it should be noted that distributing weight according only to viewing duration, just not accounting for total playing duration of event
It is different, such as the duration of one football race is long more than the news of half an hour, but user can to both interest-degrees
Can be just the opposite, it is therefore desirable to account for the ratio of the total reproduction time of event according to viewing time to calculate weight.
Assuming that event eiCorrelating event sum be n, then some correlating event e in this n correlating eventi+j's
Viewing probability calculation formula be：
Wherein, αjRepresent ei+jEffective viewing weight, n represents eiCorrelating event it is total
One in number, n correlating event of j ' expressions, αj′Represent the corresponding effective viewing weight of the correlating event, 0≤j '≤n.
Therefore, timing unit 004 needs the viewing time t of some event of viewing each to userj, viewing number of times k and should
The correlating event sum n of event is counted.
It should be noted that the n values in the event increases watched with user, viewing probability calculation formula can also increase,
The reference reservation event that set top box is obtained will also increase, and user can set a maximum reference pre- in 5-20 number range
About event numerical value, maximum to be modified with reference to the value for preengaging event number in the setting page as shown in Figure 3.
When user starts to watch the TV play that Dragon TV is played《Humble abode》When, the timing unit 004 i.e. pair《Humble abode》
Carry out timing.
