＜embodiment 1 〉
Fig. 2 is the example that television reception arrives the current broadcast program of real time record.
At first, when the user sees the broadcast program of oneself being liked, send the order that program is recorded a video, this order is passed to control unit 107 through I/O interface unit 111.This step is shown in step 201 among Fig. 2.Then, with regard to execution in step 202, control unit 107 sends the order of opening entry current target broadcast program.Afterwards, execution in step 203, the remaining space size of 108 pairs of program recording unit 110 of detection calculations comparing unit detects.Then, execution in step 204 is promptly searched the EPG information in the broadcast program information memory cell 109, the concluding time of inquiring about this broadcast program.Concluding time with broadcast program deducts now then, calculates the time span of the current target broadcast programs that will write down.This time span multiply by video bitrate and audio bit rate and, calculate the record this target broadcast programs required memory space.Execution in step 205 then, and promptly the detection calculations comparing unit 108, and the free memory of program recording unit 110 and the size of the required memory space of storage target broadcast programs are compared.
If the record cell free memory is less than the required memory space of storage target broadcast programs, with regard to execution in step 206, promptly control unit 107 is controlled notice from the remaining space deficiency of display program record cell 110 to display part 106 that send.What this time, display part 106 showed is exactly information 1, as shown in Figure 4.
Execution in step 207 and step 208 then, promptly by being stored in the EPG information of broadcast program information memory cell 109, i.e. broadcast program information, whether search target broadcast programs has replay in the recent period.This is searched, and is the name by target broadcast programs, and whether search in 109 li canned datas of broadcast program information memory cell has the identical program will be in recent broadcast.
If in 109 li canned datas of broadcast program information memory cell, do not search the recent rebroadcast information of target broadcast programs,, promptly on display part 106, show the notice of backup or the deletion of whether carrying out file with regard to execution in step 209.What this time, display part 106 showed is exactly information 2, as shown in Figure 5.If the user selects to carry out the backup or the deletion of file, promptly selected 502 keys, the user just goes file is backed up or deletes so.If the user selects file not to be backed up or to delete, promptly selected 503 keys, system just continues target broadcast programs is carried out record so, till full or user's time-out is recorded up to the record cell record.
If in broadcast program information memory cell 109 canned datas, search the rebroadcast information of target broadcast programs, that is, with the replay target broadcast programs,, promptly allow the user select whether temporarily not record and when replaying, record with regard to execution in step 210 in the recent period.What this time, display part 106 showed is exactly information 3, as shown in Figure 6, and also can be to rebroadcast informations such as user prompt replay times.If the user selects to switch to when replaying and records, promptly selected 602 keys, logger task just is switched to and carries out record, execution in step 212 when replaying so.If the user selects not switch to when replaying and records, promptly selected 603 keys, system just continues target broadcast programs to be recorded down execution in step 211 so.
When the user selects not record when replaying, execution in step 211, promptly control unit 107 shows the information that whether backs up or delete the file of in the past recording to display part 106.What this time, display part showed is exactly information 2, as shown in Figure 5.
If the user records when being chosen in replay by input units such as remote controllers, with regard to execution in step 212, promptly want the rebroadcast information of time of program of pre-recording and channel etc., the logger task of target broadcast programs is transformed into replay time execution in this rebroadcast information in broadcast program information memory cell 109 storage.When arriving the described replay time, send the order of recording target broadcast programs.Step 213 is that after the pre-recording target broadcast programs, control unit 107 is controlled the information that whether backs up or delete recorded file to display part 106 prompting users now in the past.What this time, display part 106 showed is exactly information 5, as shown in Figure 8.
After the information that shows the backup whether will carry out file now or deletion, execution in step 214, i.e. the segment of getting off was recorded in deletion just now.
If the record cell free memory is greater than the required memory space of storage target broadcast programs, then operation of recording is normally carried out, and successfully carries out record.
＜embodiment 2 〉
Embodiment 2 is television reception examples to the pre-recording signal time.The flow process of this example shows in Fig. 3.
At first, the user sends the signal of pre-recording broadcast program by remote controller to user interface section, and this signal Be Controlled unit 107 receives.This step step 301 as shown in Figure 3.Here, the user both can carry out pre-recording to target broadcast programs by the scheduling recording function of television set, can come target broadcast programs is carried out pre-recording by the EPG information in the broadcast program information memory cell again.After television set was received the signal of pre-recording, the free memory of 108 pairs of program recording unit 110 of detection calculations comparing unit detected, and promptly execution in step 302.In addition on the one hand, execution in step 303, promptly detection calculations comparing unit 108 is by the information of 109 li of broadcast program information memory cell, the time started and the concluding time of inquiring about all broadcast programs of wanting pre-recording.So since want the broadcast program of pre-recording may be not only one to inquire about the time started and the concluding time of each broadcast program, calculate the time length that each wants the pre-recording broadcast program respectively, each wants the memory space of the needed record cell of pre-recording broadcast program to calculate record.Calculate the memory space summation that all will carry out the needed record cell of program of pre-recording then.Then, the required memory space of the target broadcast programs of the free memory of 108 pairs of program recording unit of detection calculations comparing unit and all reservations of storage compares, and promptly execution in step 304.
If the record cell free memory is less than the required memory space of all pre-recording programs of storage, promptly execution in step 305, and control unit 107 is controlled the prompting of sending record cell remaining space deficiency to display part 106.What this time, display part 106 showed is exactly information 7, and as shown in figure 10, the display-object broadcast program is by pre-recording, but the free memory of record cell is not enough to record all preserved programs.And in the subscription and video recording schematic diagram, the reserved recorded information place just is registered as: the record cell deficiency, can not completely record.
Then, execution in step 306 and step 307, promptly by being stored in the broadcast program information of broadcast program information memory cell 109, whether the program of searching all pre-recordings one by one has rebroadcast information.This is searched, and is the name by the target broadcast programs of wanting pre-recording, and whether search in 109 li canned datas of broadcast program information memory cell has identical program to replay.
If want the program of pre-recording all not have the information of replaying in the recent period for each, with regard to execution in step 308, be that control unit 107 is controlled and wanted this time and the channel of the program of pre-recording to be stored in broadcast program information memory cell 109, when arriving the broadcast time of these a plurality of target broadcast programs, send record order, this target broadcast programs is carried out record.Execution in step 309 then, that is, control unit 107 is controlled and sent demonstration to display part 106 and whether carry out the backup of file or the prompting of deletion.What this time, display part 106 showed is exactly information 8, as shown in figure 11.
If in the broadcast program information of 109 li storages of broadcast program information memory cell, search the rebroadcast information of the target broadcast programs of pre-recording, then execution in step 310 and step 311, control unit 107 is controlled the prompting of sending the target broadcast programs existence replay of explicit reservation record to display part 106, and points out when can be chosen in replay and record.If being chosen in the replay time by remote controller etc., the user carries out record, then control unit 107 is controlled and is wanted this rebroadcast informations such as time of target broadcast programs of pre-recording and channel to be stored in broadcast program information memory cell 109, send the order of writing down the target broadcast programs of this existence replay to record cell 110 during the time in the arrival replay, to exist the logger task of the target broadcast programs of replaying to switch to the replay time that is searched, send the indication of the target broadcast programs of this existence replay of record in this replay time.What this time, display part 106 showed is exactly information 9, as shown in figure 12.
We notice, if record when the user is not chosen in replay in step 311, system will record the target broadcast programs of each reservation recording successively according to time sequencing so, till the record cell record is full.But, after the selection through user in the step 311, record when no matter the user is chosen in replay, carry out pre-recording when still not being chosen in replay, control unit 107 all can be after the user turns on television set, control prompting to user's " the record cell deficiency can not be finished recording task ".Thereby supervise the user that record cell is backed up or deletes.In addition, we notice that even the user records when being chosen in replay, perhaps meaning is not very big.Because if the user does not back up record cell or some file is deleted, too can't be complete when replaying record.But here we can be chosen in the selection of recording when replaying equally for one of user.This is because record when replaying, still very possible give the user more plenty of time carry out the arrangement of record cell.Such as the program that the user can have plenty of time more to record before having a look again decides which file of deletion then.
After step 310 and step 311, execution in step 312, control unit 107 sends the order of the information whether demonstration back up or delete record cell to display part 106.
If the record cell free memory greater than the storage all pre-recording programs required memory space, be execution in step 313, control unit 107 wants this time and the channel of the program of pre-recording to be stored in broadcast program information memory cell 114, recording task is switched to the described replay time carry out, send the order of recording target broadcast programs to record cell 110 during the time arriving replay.
If the user after pre-recording, has changed record cell, system will provide information, and promptly information 6, and as shown in Figure 9, the expression recording medium is replaced.And whole flow process will be got back to the initial part of flow process, that is, the remaining space to record cell calculates again.
When the remaining space that record cell occurs was not enough, the user can be by the search in EPG information, and inquiry wants recorded program whether replay is arranged.If replay is arranged, carry out when then the user can switch to replay to the recording task of broadcast program.Because recording task has been switched in the future and has carried out, the user backs up or deletes record cell with regard to the sufficient time is arranged.
The present invention had both gone for the video recording system of Digital Television, also went for the video recording system of IPTV.
According to aforesaid the present invention, above-mentioned execution mode is just realized concrete execution mode of the present invention, do not constitute for special qualification of the present invention, so, in the scope that does not break away from purport of the present invention, can carry out various rational changes.
