  Then, based on the reservation acceptance history information D5, the polling interval of the time zone with high usage frequency (time zone indicated by hatching) is set to “1 minute”, and the time zone with low usage frequency (time zone indicated by sandy hatching) The polling interval of is set to “10 minutes”, and the polling interval of the time zone where the usage frequency is at an intermediate level (the time zone shown in white) is set to “5 minutes”.

  Specifically, the polling interval is set to “1 minute” from 11:00 to 15:00 before weekdays and from 17:00 to 20:00, so the interval between 20:00 and 00:00 The polling interval is set to "5 minutes" because the frequency of use of is medium level. In addition, on Mondays, unlike other weekdays (Tuesday to Friday), it is “1 minute” for all time slots from 11:00 to 19:00 (from 5 hours to 15:00 hours on Tuesday to Friday) It is set.

  Thereafter, the polling storage information by time zone D2 stored in the polling information storage unit 52 is the same as the polling storage information by time zone D1 shown in FIG. And it becomes a process target (refer FIG. 3) of step S3.

  Since the setting of the polling interval in the time-based polling storage information D2 shown in FIG. 11 is performed based on the reservation reception history information D5, it is adapted to the usage situation of the user who uses the recording device 2. Is the optimal setting content.

  In addition, a time zone with low usage frequency is also clarified, and a longer power consumption reduction effect can be obtained by setting a longer polling interval.

  Also in the network program recording reservation system 100 of the first embodiment, after the user performs an external operation using an external device such as his / her own remote controller, the polling interval instruction information C8 obtained from the polling interval instruction information generation unit 57 is output. Thus, the same time zone polling storage information D1 as the time zone polling storage information D2 shown in FIG. 11 can be set. However, the network program recording reservation system 100B of the second embodiment does not require the external operation described above, and thus has the convenience of being automatically optimized by the recording device 2 without bothering the user. ing.

  As described above, the network program recording reservation system 100B according to the second embodiment includes the recording reservation reception information recognition unit 61, the recording reservation reception information storage unit 62, and the polling interval setting unit 63 that execute steps S21, S22, and S23. ing. For this reason, the network program recording reservation system 100B uses the recording device 2 to store the polling storage information D2 for each time zone based on the reservation reception history information D5 reflecting the execution history of the user's recording reservation information transmission processing in a plurality of classification time zones. Contents can be set automatically.

  For example, the polling time is shortened in a time zone in which a user has a relatively high frequency of performing recording reservation information transmission processing, and the polling time is set in a time zone in which a user has a relatively low frequency of performing recording reservation information transmission processing. The contents of the hourly polling storage information D2 can be set to be longer. As a result, the recording reservation information confirmation process is performed at an optimal polling interval that matches the life rhythm of each user who uses the recording device 2, and it is possible to provide a convenient operation feeling to the user and reduce unnecessary communication more accurately. Have the effect of

  In the second embodiment, the processing for setting the polling storage information D2 by time zone from the default state by the polling interval setting unit 63 has been mainly described. However, the contents of the polling storage information D2 by time zone that has already been set are described. It is also possible to implement processing that changes as appropriate.

  For example, after the time-span polling storage information D2 having the same contents as the time-span polling storage information D1 shown in FIG. 4 is set, the polling interval setting unit 63 sets the time zone shown in FIG. 4 based on the reservation acceptance history information D5. You may make it change toward the polling storage information D2 classified by time slot | zone shown in FIG. 11 from the content of the separate polling storage information D1.

  As described above, it is of course possible to use the polling interval setting unit 63 as the polling interval setting / changing unit (second polling storage information setting / changing unit).

  In the second embodiment, the recording reservation reception information D4 is included in the recording reservation information DR. However, when the recording reservation reception information D4 is not included in the recording reservation information DR, the confirmation time of the recording reservation information confirmation process May be estimated as the recording reservation reception time.

  That is, the recording reservation reception information recognition unit 61 replaces the recording reservation reception information D4 in the recording reservation information DR as the timing at which the recording reservation information transmission processing was performed when the recording reservation information DR was acquired from the server 1. The acquisition time of the recording reservation information DR may be adopted.

  In the present invention, within the scope of the invention, each embodiment can be freely combined, or each embodiment can be appropriately modified or omitted.
