See Fig. 1, the flow process of the method for a kind of program that automatically switches that the embodiment of the present invention provides is as follows, specifically comprises step S101-S103:
Step S101: the history viewing trace information obtaining user, history viewing trace information comprises programme information and history point switching time.
In embodiments of the present invention, history viewing trace information is the historical record that active user watches program, the time point switched by Pgmtime stamp recorded program.Concrete, history viewing trace information comprises programme information and history point switching time, and this programme information is specially program inventory, comprises programm name and program play times; When history switching time, point performed program handover operation for user watches in the historical record of program, be switched to the time point of actual program.Such as, user watches in the historical operation record of program, on April 1st, 2015 10:55:00 be switched to central two programs from CCTV-1 program, then this time point " 10:55:00 on April 1st, 2015 " is history point switching time of central two programs; Meanwhile, this time point " 10:55:00 on April 1st, 2015 " is also history point switching time of CCTV-1 program.
Step S102: according to above-mentioned history viewing trace information, determine the preference degree of user to each program respectively.
Concrete, in embodiments of the present invention, in above-mentioned steps S102, determine that the step of each program preference degree specifically comprises step S201-S203, specifically shown in Figure 2:
Step S201: determine effective program according to history viewing trace information, effective program is the program that playing duration between two program history switching time points is greater than preset duration.
In the embodiment of the present invention, program history switching time, point watched the time point performing handover operation in the historical record of program for active user, between two adjacent history are put switching time, namely there is broadcast program.Concrete, effective program is the program that playing duration between two adjacent history points switching time is greater than preset duration; And the program that playing duration is less than preset duration is invalid program, thus effective program and invalid program can be distinguished, and then perform subsequent operation.
Such as, preset duration is 5 minutes, and user watches in the historical operation record of program, on April 1st, 2015 10:55:00 be switched to central two programs from CCTV-1 program, and on April 1st, 2015 11:10:00 be switched to CCTV-3 program from central two programs; In the programme information of central two programs, on April 1st, 2015 is program A before 10:56:00, afterwards for program B.Therefore, between two adjacent history points switching time " 10:55:00 on April 1st, 2015 " and " 11:10:00 on April 1st, 2015 ", there are two programs (i.e. program A and program B) in central authorities' two programs, and the playing duration of program A is 1 minute, the playing duration of program B is 14 minutes; Therefore, program A is invalid program, and program B is effective program.
Step S202: determine effective playing duration of effective program and effectively play frequency, effective playing duration is total playing duration of effective program in the first predetermined period, effectively plays the broadcasting time that frequency is effective program in the second predetermined period.
Wherein, the first predetermined period and the second predetermined period are identical or different predetermined period.Because general program is play once for every 7 days, in the embodiment of the present invention, the first predetermined period and the second predetermined period are all set to one week duration, can certainly be set to two weeks durations or month durations etc.Still be effective program for above-mentioned program B, this effective playing duration is program B playing duration altogether in week age; Effective broadcasting frequency is the broadcasting time of program B in week age, wherein, as above, shown in example, between above-mentioned two time points " 10:55:00 on April 1st, 2015 " and " 11:10:00 on April 1st, 2015 ", program B is effective program, be then a broadcasting time of program B.
