Realize that in order to design the method for subscribing can adopt system configuration described below, in this system configuration, when arriving the time of carrying out, satellite broadcast receiver 100a and recording apparatus 110 can be carried out independently according to the subscription data of storage and subscribe operation.Can also give the function that one of satellite broadcast receiver 100a equipment can remote control recording apparatus 110, thereby when arriving when carrying out the time of subscribing, satellite broadcast receiver 100a can carry out reservations by remote control recording apparatus 110.In this case, except that relevant apparatus identification code 203, the subscription data 200 of subscription data administrative section 105 management does not comprise the data that indicate whether other device of remote control among the satellite broadcast receiver 100a.
And except that input identification code 303, the subscription data 300 of subscription data administrative section 115 management also comprises the data that indicate whether by other device remote control in the recording apparatus 110.
Explain below with reference to Figure 15 and regularly to subscribe charge program how to record satellite broadcasting program for example etc.
Step according to above-mentioned timing reservation, suppose that subscription data administrative section among the satellite broadcast receiver 100a 105 stores the subscription data of the charging TV program 1510 (for example sports cast) in 1502 these times of time started 1501 to concluding time of plan, and storage is from the subscription data of another program 1520 of time started 1504 beginning of plan, and program 1520 is after program 1510.
Whether in the first few minutes of the planned start time 1501 of the charging TV program of subscribing 1510, regularly subscribing part 104 obtains up-to-date programme, and check program 1510 and will begin in the time of plan.
Regularly subscribing part 104 this moment also has another method to obtain up-to-date programme at interval with regular time.
If program 1510 begins according to schedule, when to predetermined time started 1501, regularly subscribing part will together begin program recording with recording apparatus 110.
On the other hand, if program 1510 begin to lag behind definite plan, regularly subscribes part and will obtain the concluding time of program, and whether the concluding time of checking program conflicts mutually with the meter time started 1504 of the reservation program 1520 of back.If clash, then this influence is notified to the operator.
Figure 16 has shown the picture frame example 1600 that shows on monitor 120.If elect 1601 on picture frame 1600, then the timing of satellite broadcast receiver 100a is subscribed part 104 and will be changed a reservation ticket reserving time 202 in the subscription data 200 of program 1510, and the relevant subscription data 200 of deletion and reservation program 1520.Simultaneously, require the timing of recording apparatus 110 to subscribe part 114 and change a reservation ticket reserving time 302 in the subscription data 300 of program 1510, and require deletion to subscribe the subscription data 200 of program 1520.
According to this requirement, the ticket reserving time 302 in the subscription data 300 that part 114 is stored in change the reservation program 1510 in the subscription data administrative section 115 is subscribed in timing in the recording apparatus 110, and the subscription data 300 of program 1520 is subscribed in deletion.Select 1602 if indicate, video recording will be recorded reservation program 520 in the middle of the program of subscribing program 1520, but the operator also can select to have the program of priority.
Then, begin to record the reservation program from the definite plan time started 1501 after, when a few minutes before the concluding time 1502 of plan, whether the timing of satellite broadcast receiver 100a is subscribed part 104 and is obtained up-to-date programme, and check program 1510 and finish by preset time.Regularly another method can be with the up-to-date programme of regular time interval acquiring in addition for predetermined portions 104.
If program 1510 finishes according to plan, when to concluding time of subscribing 1502, satellite broadcast receiver 100a will finish recording of program with recording apparatus 110.
On the other hand, if program 1510 (for example, sports cast normally) time of continuity has surpassed the concluding time of plan, and part 104 is subscribed in the timing of satellite broadcast receiver 100a will give the operator with this result notification by displayed map picture frame 1600 on monitor 120.If select 1601 on picture frame 1600, part 114 is subscribed in the timing of recording apparatus 110a will delete the subscription data 200 of subscribing program 1520, and require the timing in the recording apparatus 110 to subscribe the subscription data 200 that program 1520 is subscribed in part 114 deletions.
The operation of surveillance always finishes up to subscribing program 1510 in whole recording process, and the performance of program 1510 is transferred to the timing reservation part 114 of recording apparatus 110.According to this situation, the subscription data 300 that part 114 deletions are stored in the reservation program 1520 in the subscription data administrative section 115 is subscribed in the timing of recording apparatus 110.And continue program recording till (appearance) notice from the program end of satellite broadcast receiver 100a.If select 1602, recording apparatus 110 will be recorded the program 1520 of reservation from the centre of program 1520, also can allow the operator select to have the program of priority.
This set can be adapted to subscribe the accident time-delay of program neatly.Though notification operator deletion subscription data 200 in above-mentioned example, but can also when subscription data 1510 is set, pre-determine its priority, partly automatically delete subscription data 200 thereby when contingency unexpectedly changes subscription data (for example program time-delay), can make regularly to subscribe.
At this, though satellite broadcast receiver 100a is that input unit, recording apparatus 110 is relevant apparatus in the said system structure, recording apparatus 110 is that the system configuration of relevant apparatus also is fine for input unit, satellite broadcast receiver 100a.In this case, recording apparatus 110 orders are coordinated regularly and are subscribed, and be stored in subscription data in the subscription data administrative section 115 in the recording apparatus 110 respectively and in the subscription data administrative section 105 in the satellite broadcast receiver 100a, unique difference is the subscription data administrative section 115 management subscription datas 200 in the recording apparatus 110, subscription data administrative section 105 management subscription datas 300 in the satellite broadcast receiver 100a, but its treatment step to above-mentioned enforcement method similar.
