As shown in Figure 2, the flow process of performance recording is, S1 begins, and S2 begins program recording, and whether S3 records and finish, and according to judged result, carries out subsequent step, if record end, then S9 records end; Otherwise S4 analyzes current PSI/SI information, judges whether S5 is advertised event, and in this way, then S6 suspends and to record, and as not, then repeats the S3 step, S6 suspend record after, judge that again the S7 advertised event finishes, in this way, then S8 continues to record, as otherwise continue the S6 step.
Broadcast in the mechanism at the wheel of NVOD, a general method is the segmentation that audio, video data is divided into regular length, then these segmentations is broadcasted in several channels according to certain rules again.
PVR records and can record a plurality of programs under same frequency, can also record a plurality of programs if having a plurality of receiving elements (tuner) under different frequent points.
In the TS data, be directed to single program, a time-shift service is represented the program fragment of a time period, and can find each program fragment by reference_evnet_id.No matter be film or serial, the name by reference event can obtain all TV play.So just can be by reference professional (ReferService_id), corresponding reference event (ReferEvent_id), corresponding time migration incident (ShitfEvent_id).By searching all reference event names, promptly can obtain all same films or same TV play.By recording complete time slice of each reference event, can record down complete a film or a complete TV play fully.Because each time slice obtains the programme information (looking audio frequency id) of this incident, all programs under the parallel record of PVR then by the id of skew professional (SiftService) among the TS.
The crucial process points of the embodiment of the invention is:
One, by input need the recorded program name, obtain all reference event names.Obtain by the name that contrasts all reference event in the present embodiment.
Two, at all reference event of looking for, find parallel as far as possible complete time slice.Obtain with reference to the start and end time of the event of professional correspondence by contrasting each.
Detailed process is as follows:
One. recording arrangement processing unit filtering services description list (SDT table)
(TS_PID=0x0011 TABLE_ID=0x42/0x46), resolves the ID that NVOD_reference_descriptor obtains all time migration business that a certain NVOD comprises with reference to business, i.e. program number among the PMT;
Resolving Time_shifted_service_descriptor obtains with reference to professional corresponding reference node purpose ID.
Two. (PID=0x0012 TABLE_ID=0x4e/0x50) obtains program start time to recording arrangement processing unit filtrating program Event Information Table (EIT table), and length is encrypted and ruuning situation
Resolve title and brief introduction that Short_event_descriptor gets program;
Resolve time_shifted_event_descriptor and obtain corresponding NVOD with reference to service numbers;
Parsing content_descriptor obtains the classified information of program;
Three. recorded program as required, search relevant reference event information.For example record a film with upper, middle and lower three collection (on electrodeless, electrodeless down, electrodeless in), by the contrast programm name electrodeless can obtain three reference event name, and by relevant event information.
Four. according to the reference event information of obtaining, obtain each incident time corresponding fragment, and analyze and to obtain walking abreast the time period that can completely record.Obtain the relevant programme information (audio frequency and video pid) of each time slice (time shifting case) then.
Five. judge the program of synchronous recording according to whether at same frequency, all can recorded program to carry out synchronous recording, perhaps one by one automatic recording all can program.
As shown in Figure 1, if professional 1-business 6 is a TV play, when watching in professional 1 program, then can recoding service 2, the program in professional 3, professional 4, professional 5. and then when seeing program in professional 2, program that can synchronous recording business 6.
If a program duration is T in the business, record six collection program required times less than 2T.If adopt common pattern, then need 6T.
Another object of the present invention is to filter out the advertising programme information in the program in recording process, record a continuous TV programme.On the program recording basis of routine, carry out the improvement and the technical processing of hommization, solved the problem of the selected program filtering advertisement of PVR automatic recording user, a kind of method of PVR program recording filtering advertisements is provided.
For achieving the above object, in one embodiment of the invention, realize by following technological means.
The precondition that realizes this target to be advertising message in TS stream be incident is independently analyzed by psi/si and can be analyzed this advertised event.And the advertised event name is similar to " advertisement ", " about * * * advertisement ", " AD " or the like, advertisement all is an incident independently in present most of program broadcasting system, as advertisement in the EPG information of central authorities' one cover is an independently incident, so the technological means of present embodiment has its practical significance in actual applications.
Realize that this target has two levels, a level is on existing broadcast items system-based, fuzzy filtering advertisements information.Second level is to cooperate with front end operator, realizes accurate advertisement filter.The two all is to screen by this channel program information, mainly is the EPG information of program, PF information and relevant descriptors.By the start and end time of contrast incident name and corresponding event, determine whether to record the program in this time period.
Present embodiment is introduced the function design of first level, referring to Fig. 3, the method for judging advertised event at first is set, as the keyword fuzzy query is set, and keyword query combines judgement with duration.
Process step comprises that mainly S10 begins, and S11 receives EVENT information, and S13 analyzes EVENT information, judges whether the S15 event name is advertisement name keyword, is that then S17 is confirmed to be advertised event, otherwise S18 finishes; In addition, carry out S12 synchronously and receive PSI/SI descriptor information, S14 analyzes PSI/SI descriptor information, judges whether the S16 descriptor is advertisement name keyword, is that then S17 is confirmed to be advertised event, otherwise S18 finishes.
The user imports the expectation recorded program or recorded program is wished in reservation, when recording this program, need note the event name (event name) of current program recording and the duration that need record.
The equipment background program obtains its EPG information and P/F information according to this channel information then, analyze the event name of current program, whether more whether be the recorded program event name, and judge the event name that this channel is current by resolving the PSI/SI/ descriptor, be the event name of recording.Be that the incident that the user records then continues to record; If the event name of EPG information of analyzing or PF information analysis is identical with the event name of PSI/SI/ descriptor analysis and be not, judge that then this event name is an advertised event, be then to suspend to record wait, and judge whether record duration finishes, finish then to wait for occur judging whether to be to continue program recording or withdraw from up to next incident.
This mode has certain limitation, because the incident name by information judges with the keyword contrast of setting, can not judge to be advertisement accurately, can only this incident of fuzzy Judgment advertised event whether.
Present embodiment is introduced the implementation procedure of second level, and second level is to realize with the radio and TV operator is collaborative, accurately the filtering advertisements incident.The radio and TV operator is generating EPG information, when PF information or other form, increases a type specification for advertised event in descriptor, and identifies for advertised event in descriptor.
Referring to Fig. 4, process step comprises that mainly S19 begins, and S20 analyzes PSI/SI information, and S21 judges whether it is the time type specification, whether is that advertised event is described in this way, then S23 judges it is advertised event, and S24 finishes; As not, judge then whether the S22 information description has advertisement to indicate descriptor, and then S23 judges it is advertised event in this way, as otherwise S24 finish.
And in the application program, when program recording, and note the event name (eventname) of current program recording and the duration that need record.The background devices program is analyzed the event type describing word and the parsing PSI/SI/ descriptor of operator's definition and is judged that current incident is an advertised event according to this frequency point information.Be then to suspend to record wait, finish (concluding time according to each incident is judged), judge that recording duration does not also finish then to continue to record up to this advertised event.If not, and in recording duration, then continue to record.
In this way,, in recording process, can filter out fully, realize recording accurately management because each advertised event is a precise marking.
In addition, the invention still further relates to a kind of performance recording equipment, can be television set or Related product, mainly comprise receiving element and processing unit, receiving element received signal and data, processing unit is handled according to the information and the data that receive, according to the method for recording of introducing above object content is recorded then, thereby realize the complete recording function of recording arrangement and the function of filtering advertisements content, promoted the quality and the performance of recording arrangement.
The invention provides a kind of hommization that has more, method for recording more flexibly satisfies user's individual sexual demand, and the space of having reduced disk as much as possible, and has filtered uncorrelated contents such as advertisement, and the time of recording has also recorded soon much than one way.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range that claims were limited.
