Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain the present invention, and be not used in limitDetermine the present invention.
The invention provides a kind of time shift program player method, with reference to Fig. 1, Fig. 1 is that time shift program of the present invention is broadcastPut the schematic flow sheet of method one embodiment, in one embodiment, this time shift program player method, comprisesFollowing steps:
Step S100, obtain time shifting broadcasting time Tstar, live time Tcurrent, entanglement time TterrWith time shift time Tdis。
Time shift program playing device receives time shift instruction, intercepts time shift program looking in the time of current time shifting broadcastingFrequently image information, according to intercept current time shifting broadcasting time video image information, obtain TV in time shiftChannel information and time shifting broadcasting time T while playing current videostar, wherein, time shifting broadcasting time T starRefer to the time of the programme content of spectators playback time in the past, such as " from you of star " time shift programTime shifting broadcasting time T star is 10 points, from 10 broadcastings " from you of star ".
Time shift program playing device inquiry EPG (electricalprogramguide, electric program menu letterBreath), according to the live time T current of TV programme described in the acquisition of information of EPG record. As table 1Show, table 1 is EPG, and as shown in Table 1, upper " from you of star " recorded of EPG is at channel CCTV1The reproduction time of playing the first collection is 10: 30, can know " from you of star " live timeBetween Tcurrent be 10: 30.
Table 1
The time that entanglement time T terr comprises while intercutting other video images for mistake, entanglement time T terrSource mainly contains two kinds: a kind of is because the calibration of each local time of the whole nation and latitude is different, transmitting stationIn program playing process, can carry the transmission of other images secretly, while playing current program, intercut suddenly itThe time of its video, for example, when spectators are watching " news hookup " of CCTV1, TV intercuts suddenlyTime of ten seconds is play " from you of star ", and this time of ten seconds of intercutting is entanglement time T terr;Another kind of: local receiving platform is found the time span that the picture material of head station transmission has other program to occur.Entanglement time T terr can be captured the error message of other videos and directly be obtained by time shift program playing deviceGet, such as, the wrong time summation that grabs other video playback videos is 30 seconds, and time shift joint is describedOrder playing device is 30 seconds at the entanglement time T terr of time shifting broadcasting. Time shift time T dis is fixed configurationsTime, arranges according to user's actual needs, such as user is set to 30 minutes, and in theory 30After minute, carry out time shifting broadcasting.
Step S200, according to described time shifting broadcasting time Tstar, described live time Tcurrent, described mistakeRandom time TterrWith described time shift time Tdis, determine simultaneous bias time Tshift。
Time shift program playing device is according to time shifting broadcasting time T star, live time T current, entanglement timeTterr and these time parameters of time shift time T dis, calculate simultaneous bias time T shift, simultaneous biasTime T shift=Tstar-Tcurrent-Tterr-Tdis, as shown in Table 2, by calculating, draws simultaneous biasTime T shift.
Table 2
Step S300, according to described simultaneous bias time T shift, time shift program is revised.
Time shift program playing device is according to the simultaneous bias time T shift calculating, to broadcasting of TV programmeThe time of putting is revised, and the TV programme of playing are synchronizeed with default time shift program, for example, and furtherReferring to Fig. 2, in CCTV2 channel, live time T current is 10: 30 minutes, time shifting broadcastingTime (Tstar) be 10: 1, the time shift time T dis that user arranges is 30 minutes, the mistake of obtainingRandom time T terr is 3 minutes, by formula Tshift=Tstar-Tcurrent-Tterr-Tdis, calculates sameStep shift time Tshift is negative 4 minutes, time shift program content is skipped after 4 minutes and is play; If meterCalculating simultaneous bias time T shift is positive 3 minutes, by time shift program content caching postpone 3 minutes laggardRow is play.
The time shift program player method that the present embodiment provides, revised the entanglement time of time shift program,Experience thereby strengthen user, promote spectators' satisfaction.
