Description
Technical field
The present invention relates to a kind of management method of preserved program.
Background technology
Along with the development of Digital Television, the user also increases day by day to the functional requirement of digital TV set-top box, and particularly the user wishes to break away from and watches the passive and helpless of TV, the TV programme that can watch over easily and will play.In this case, more and more major companies begin to develop PVR (Per sonal VideoRecorder, personal video recording) set-top box.The PVR set-top box generally adopts the built-in hard disk of IDE or ata interface, the PVR technology is applied in the digital TV set-top box, realized time shift, recorded a video and retreated, function such as F.F., time-out, for the user has brought digitized unusually brilliant and interactive following one's bent.But, want to provide the service of hommization more, perfect displaying predetermined programme is play and scheduling recording function is necessary.
But in the existing set-top box, there is a shortcoming: for various reasons, front end TV station may change the broadcast time of broadcast items and arrange, so, in the set-top box the program of pre-recording/broadcasts just can can't carry out pre-recording and broadcast accurately because the time changes.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of can be according to the change of beginning and ending time of front end preserved program and the method for the beginning and ending time in renewal this preserved program information of having stored automatically.
For addressing the above problem, the present invention proposes a kind of preserved program management method, may further comprise the steps:
A, judge whether preserved program is effective, if effectively, execution in step b then;
B, judge whether the beginning and ending time of described preserved program change,, then upgrade the described beginning and ending time if change.
Wherein, whether service identifiers and/or the event identifier of step a by judging preserved program exists and realizes, if exist, then think effectively, otherwise invalid.
Wherein, step b compares realization by the beginning and ending time with this preserved program in former beginning and ending time of preserved program and the current electronic program guides, if change the beginning and ending time of then upgrading this preserved program.
In addition, also comprise step c, preserved program is sorted by zero-time.
Wherein, whether described service identifiers exists by judging that television channel lists realizes, whether described event identifier exists by judging the electronic program guides realization.Perhaps, whether described service identifiers and event identifier exist all by judging that electronic program guides realizes.
Further, when judging that described preserved program is invalid, then delete this preserved program record.
Wherein, described preserved program can be to preengage according to the electronic program guides reservation or by the time.
On the other hand, the present invention also provides a kind of storage means that can save preserved program information stores space, and it is managed preserved program information dynamically by definition class and chained list.
Implement the present invention and can realize the automatic renewal of the beginning and ending time of preserved program, thereby guaranteed to preengage the accuracy of playing, and then made things convenient for the user.In addition, owing to adopt the method for class and chained list to come dynamic managing reserved programme information, saved storage resources valuable in the set-top box.
Description of drawings
Fig. 1 is the structured flowchart of an embodiment of using the set-top box of a kind of preserved program management method of the present invention;
Fig. 2 is based on the flow chart of an embodiment of a kind of preserved program management method of set-top box among Fig. 1.
Embodiment
With reference to figure 1, illustrate the structured flowchart of an embodiment of the set-top box of using a kind of preserved program management method of the present invention.As shown in the figure, comprise tuner 11, channel decoding module 12, demultiplexing module 13, hard disk 14, decoder module 15 and A/V output module 16.
Its roughly the course of work be: the analog signal from cable television network exports channel decoding module 12 to after tuner 11 demodulation, channel decoding module 12 is decoded and with decoded TS (TransportStream, transport stream) stream exports demultiplexing module 13 to, demultiplexing module 13 is PES (Packetised Elementary Streams with TS flow data demultiplexing, Packet Elementary Stream) stream, described PES stream can be by two passage outputs, i.e. passage shown in the figure 1 and passages 3.Wherein, passage 1 directly exports decoder module 15 to carry out audio/video decoding and exports the 16 output demonstrations of A/V output module to, and 3 in passage exports described PES stream to hard disk 14 and stores.After the user starts time-shifting function, the program that broadcasts is decoded to export through passage 1 and is shown, also be stored in the hard disk 14 on the other hand through passage 3, if the user need retreat to watch and broadcast picture, then export the corresponding PES flow data of storage in the hard disk 14 to decoder module 15 by passage 2 and carry out exporting demonstration by the A/V output module behind the audio/video decoding, thereby realize time shift.For the time-out of the program that is broadcasting, time shift operation such as put slowly, in like manner also can realize.
Equally, when program recording by user or pre-recording, also be the storage of carrying out the PES stream of respective program by hard disk 14.When playing recorded program, just corresponding PES flow data in the hard disk 14 is outputed to decoder module 15 by passage 2 and carry out audio/video decoding output, finally export demonstration by the A/V output module.
Set-top box shown in Figure 1 only is an embodiment, if pay when watching program certainly, then needs to add Conditional Access Module and descrambling module etc.; Equally, above-mentioned hard disk is a kind of storage mode, can also adopt flash disk, CD etc.In another embodiment of the structure of set-top box, can adopt two demultiplexing module, promptly on the basis of Fig. 1, increase a demultiplexing module again, the input of the demultiplexing module of this increase is from the TS stream of channel decoding module 12 outputs, and its output exports hard disk 14 to by passage 3 (this moment, passage 3 was not connected with demultiplexing module 13).If the effect of two demultiplexing module is in order to realize while seeing record, promptly the user records other one road program when watching one road program, at this moment two demultiplexing module respectively demultiplexing go out the PES flow data of described two-way program for playing and recording.
With reference to figure 2, illustrate workflow based on an embodiment of a kind of preserved program management method of set-top box among Fig. 1.In the present embodiment, preserved program is stored in the set-top box with the way to manage of class and chained list dynamically, dynamically being meant when the preserved program informational needs is stored herein, then create the example of a class dynamically and dynamic memory allocated space as required in the internal memory of set-top box, form with class and chained list is come managing reserved programme information, for example, if have preserved program information to store now, then in system, create the example (being referred to as the preserved program record set) of a class, and the preserved program information that will need to store stores in the sequential chained list successively, can save memory space like this.As shown in the figure, present embodiment may further comprise the steps:
Step 201 has judged whether preserved program, if having, then flow process is descending, otherwise execution in step 220; Its realization can be in the following ways, at first judge whether preserved program record set (just having judged whether to define the class of a storage preserved program information), if do not have, then explanation does not have preserved program, if having, whether the number of then judging the preserved program in this preserved program record set again is 0, if 0, no preserved program then is described, if be not 0, then explanation has a preserved program, and wherein each preserved program is all as such object instance; Whether, can by the pointer of judging described preserved program record set be null value realize, if null value then illustrates no preserved program, otherwise then has if, judging whether the number of the preserved program in the preserved program record set is 0 here.
Step 202 judges successively whether the Service ID (service identifiers) of preserved program exists, if do not exist, then deletes corresponding preserved program information, otherwise the flow process continuation is descending; Whether the Service ID that judges all preserved programs in this step exists, and is deleted for the non-existent preserved program information of Service ID.
Step 203 judges successively whether the Event ID (event identifier) of preserved program exists, if do not exist, then deletes corresponding preserved program information, otherwise the flow process continuation is descending; Whether the Event ID that judges all preserved programs in this step exists, and is deleted for the non-existent preserved program information of Event ID.
Step 204 judges whether the beginning and ending time of preserved program changes, if change, then flow process is descending, otherwise execution in step 206; Because when preserved program, just at that time electronic program guides (ElectronicProgram Guide, the EPG table) time started and the concluding time of this program have been obtained in, and it is stored in the preserved program information, in this step, set-top box obtains the up-to-date EPG table from cable network, and with the program start time in the preserved program information and program end time respectively with this up-to-date EPG table in the program start time of this preserved program and program end time relatively, if change, then flow process is descending.Seeking described preserved program in the EPG table can locate by the Service ID and the Event ID of this preserved program.
Step 205, the beginning and ending time of update reservation program also successively sorts by zero-time again, and pointed article one preserved program record of described preserved program record set; This step is replaced the start time information of former storage with the up-to-date start time information of described preserved program, and joyful programs all in the described preserved program record set is resequenced according to the zero-time of program, and with article one preserved program record after the pointed rearrangement of this preserved program record set.
Step 206 judges whether current preserved program is in pending state, if then the flow process continuation is descending, otherwise execution in step 214; Current preserved program described in this step is the current preserved program pointed of the pointer of described preserved program record set, and whether also described pending being meant do not carry out playing, and it can be realized by judging status indication.
Step 207 judges whether this preserved program will begin to record/play after the setting-up time section, if then flow process is descending, otherwise execution in step 220; Described setting-up time reality is carried out countdown time of playing for preserved program, and it can solidify the user when dispatching from the factory can't change, and has default value when perhaps appearing on the scene, and the user can revise this time as required.Can realize by the return value of function revising; Whether the deterministic process of this step can add the above setting-up time section and realize more than or equal to the initial recording/reproduction time of described preserved program by judging the current time, if, then flow process is descending, otherwise execution in step 220, wherein the current time can be at TDT (the Time and Date Table that resolves automatic network, the time and date table) comes by the set-top-box system clock calculation on the basis of table and TOT (Time Offset Table, TOT Time Offset Table) table; In one embodiment of the invention, described setting-up time section can be made as in 30 seconds, promptly to current time+30s 〉=whether the preserved program zero-time is set up is judged, and carry out subsequent process according to judged result.
Step 208 is returned and is about to carry out prompting; This step is display reminding on display screen (for example " preserved program XXX is about to begin playing "), this information can be solidificated in the memory of set-top box when appearing on the scene, the user can't change, and perhaps the user also can require to utilize the return parameters of a certain function this information to be made amendment etc. according to the personalization of oneself.
Step 209, other deposits this preserved program record and arrives the back in zero-time and carries out this reservation; Promptly, this preserved program record is stored in the another location in addition to be used for other functional modules of set-top box, playing function module etc. for example, simultaneously, after arriving, zero-time carries out this reservation, just,, then carry out the reservation of this program and play if this program is play for reservation if this preserved program is that pre-recording then carries out recording of this program.Wherein, zero-time whether arrive can increase by one relatively the deterministic process of current time and described zero-time realize.
It should be noted that, in another embodiment of the present invention, between step 208 and step 209, can also there be the reception user to confirm the step of instructing, promptly when screen display be about to record/during broadcast information, at this moment the user is not if want to carry out the pre-recording of this program, then can send instruction to set-top box by the function key of cancellation reservation, set-top-box system is cancelled the reservation of this program and is deleted this preserved program record at described preserved program record set after receiving the instruction of cancelling reservation, and turns to step 201 to carry out again; If the user does not send the instruction of cancellation preserved program, then execution in step 209.
Step 210 judges whether described preserved program is pre-recording, if then execution in step 211, otherwise execution in step 212; This step can realize by judging the task type mark in the preserved program record.
Step 211 is returned and is recorded start information; Inform that promptly set-top-box system and/or user (can be shown on the screen) record beginning, it can be realized by return value.
Step 212 judges that whether described preserved program is that reservation is play, if execution in step 213 then, otherwise execution in step 214; This step can realize by judging the task type mark in the preserved program record.
Step 213 is returned reservation and is play start information; Inform that promptly set-top-box system and/or user (can be shown on the screen) play beginning, it can be realized by return value.
Step 214 judges whether this preserved program is carried out, if then execution in step 215, otherwise execution in step 219; Promptly for the reservation broadcast program, judge whether to play, for the pre-recording program, judge whether to record.
Step 215 judges whether this preserved program finishes after the setting-up time section, if then execution in step 216, otherwise execution in step 219; In this step about the associated description of elaborating of setting-up time section in can refer step 207, it can add the above setting-up time section whether more than or equal to concluding time of this preserved program by judging the current time, if set up, then explanation closes to an end, then execution in step 216, otherwise execution in step 219.
Step 216 is returned the prompting that closes to an end; The specific descriptions of this step can refer step 208.
Step 217, other deposits this preserved program record; Be about to this preserved program record and be stored in other functional modules uses of another memory location for set-top box.
Step 218 is returned pre-recording/broadcast ending message; Inform that promptly set-top-box system and/or user (can be shown on the screen) record/play end, this step can realize by function return value.
Step 219 judges whether next preserved program record exists, if exist, then execution in step 206, otherwise, execution in step 220; This step can be by judging described preserved program record set the return value of pointer judge, if return improper value during with the pointed next record or point to article one reservation recording etc., then explanation does not have next preserved program record, otherwise thinks that next preserved program record exists.
Step 220 finishes this preserved program control flow.
The reserving method of described preserved program, set-top box can be realized by dual mode, promptly according to the reservation of EPG table and/or according to time reservation.When the user prepares to preengage a certain program, set-top-box system prompting user can be according to any reservation the in the above-mentioned dual mode, if the user has selected according to time reservation, then the user need import the time started of program and record duration this moment, perhaps import the zero-time of program, if the user has selected according to the reservation of EPG table, then set-top-box system is stored the relevant information (comprising zero-time etc.) of this program in the EPG table automatically.Wherein, if the user has selected to preengage by the time, then obtaining at TDT (Time and Date Table, time and date table) table of resolving automatic network and TOT (TimeOffset Table, TOT Time Offset Table) table basis of current time goes up to come by the set-top-box system clock calculation.
Above disclosed is a kind of preferred embodiment of the present invention only, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of doing according to claim of the present invention still belongs to the scope that the present invention is contained.
