The present invention pays close attention to temperature according to the rating probability of TV programme and user to decide TV programme putting in order in TV program list, make the user in TV program list, find the TV programme of oneself liking fast, show the hommization of Digital Television and make things convenient for the user.
As shown in Figure 1, present embodiment comprises step:
Step S110: when user's TV reception, add up the viewing time of each TV programme and watch number of times, and calculate the average each viewing time of acquisition.
In conjunction with shown in Figure 2, specifically, performing step S110 specifically comprises:
Step S111: a program viewing information table is set, and each list item writes down three contents of a TV programme respectively: " the program viewing time " of this TV programme, " program viewing number of times " and " average each viewing time "; Wherein, " average each viewing time " is to be divided by to calculate by " program viewing time " and " program viewing number of times " to obtain.All list items of this table are initialized as 0 entirely during the first rating of user, and expression is not watched as yet, and the order of the program of all list item correspondences is the program natural ordering behind the program searching.
When user's TV reception, the viewing time of this TV programme of Dynamic Maintenance: when the user began to watch a certain TV programme, setting " beginning viewing time variable " was write down it and is begun viewing time point A; When the user stopped to watch this TV programme, setting " end viewing time variable " was write down it and is stopped viewing time point B; Obtain " this viewing time " that the user watches this TV programme from the difference of " finishing the viewing time variable " value and " beginning viewing time variable " value, " this viewing time " is set writes down this difference (B-A); With the former value C addition that should " program viewing time " to writing down in should the list item of program in " this viewing time " and the program viewing information table, obtain up-to-date program viewing time D=C+ (B-A), again it recorded the program viewing information table " corresponding list item.
So, at every turn watching of this TV programme all repeated said process, make in " program viewing information table " to write down in should the list item of program should " program viewing time " value with the continuous synchronous refresh of the accumulation of user's viewing time.All programs are all done above processing, make in each list item of " program viewing information table " and writing down all the time by current all programs up-to-date " program viewing time ".
Step S112: when the user finishes watching of a TV programme, just inquire about " program viewing information table ", obtain the up-to-date program viewing time D of this program.
Step S113: the program viewing time that this time D is corresponding with each list item in " program viewing information table " is carried out size relatively, obtains the list item quantity P greater than this viewing time.
Step S114: the viewing information of this TV programme being recorded " program viewing information table " middle index value is in the list item of P.Be implemented in " program viewing information table " with this, by rating probability (being the length of viewing time) ordering, the viewing information with each TV programme of order records the program viewing information table " in each list item.
Step S120:, obtain the current temperature of watching of each TV programme, and the current temperature of watching is set to the hot broadcast TV programme greater than the TV programme of threshold value with this viewing time of each TV programme average each viewing time divided by correspondence.
The structure of one " hot broadcast programme information " is set, comprises one " hot broadcast program information table " and one " current hot broadcast number of programs "; " hot broadcast program information table " has the list item (such as being 10 list items) of fixed number X, can write down program names, program number and " the current temperature of watching " of X hot broadcast program at most; So " current hot broadcast number of programs " maximum is X.Structure during initialization " hot broadcast programme information " internal information all is set to 0.In addition, the flag bit of " current program whether hot broadcast " being set, is to represent non-hot broadcast at 0 o'clock during initialization.
