In addition, if the user wants to secure the recording space in another way, the user presses cancel to secure the recording space. Here, the recording scheduled to be deleted is a recording that has not been saved by the user. When providing recordings to be deleted, such recordings may be provided at random, or may be provided in order of the oldest recordings among the recordings that have not been set.

In this case, the user can directly set a retention period for the recording setting of the recorded material. The setting time point is an arbitrary time point, and may be made through the end point of reproduction, the selection of recording material, or the like.

If the user selects confirmation 226 for the scheduled recording to be deleted (S106), the displayed scheduled recording to be deleted is deleted (S107). At this time, if the recording space is insufficient (S108) to go back to step S104 to repeat the above operation. However, if the recording space is not short, the reserved recording registration is completed (S109).

In addition, if the deletion is not performed for the scheduled recording to be deleted in step S106, the recording recording reservation setting is canceled (S110), and the reserved recording registration is completed, so that the user can later secure a recording space or notify before recording starts. In addition, the recording space may be secured again.

If there are no recordings to be deleted in step S104, the oldest recording list is provided along with a low capacity warning message (S111, S112). At this time, if the deletion of the oldest recording provided is checked (S113), the shortage of recording space is once again confirmed. Here, the criterion for extracting the oldest recordings may be one year, include a list of months before the current date, or include one or more lists of the oldest recordings and adjacent recordings when sorted by date.

In this case, when there are no recordings to be deleted, all recordings are set to be preserved. In this case, one or more oldest recording lists are provided. The recording space preparation information 200 at this time is as shown in FIG. 5.

Then, the user is notified whether the recording space is insufficient by calculating the reserved recording amount for a predetermined period (S142 and S143). Here, the predetermined period may be set to a specific period such as weekly or seven days, two weeks, one month. Alternatively, the user can set a certain period at random intervals, or operate the recording space management mode (manual or automatic) when the number of non-period recording lists is over a certain number. It can also be enabled to operate in recording space management mode when the threshold remains below the threshold.

As a result of checking whether the recording space is insufficient (S143), if the recording space is insufficient, the user is notified of the insufficient space and provides a list of recordable deletions (S144 and S145). At this time, if the user selects the deletion while viewing the record list that can be deleted (S146), the recordings of the provided list are deleted. Thereafter, the procedure as described above is performed again by checking whether the recording space is insufficient.

In other words, in order to calculate the reserved recording amount for a certain period, the user is informed in advance of the insufficient amount so as to provide sufficient recording space, and the space necessary for recording in advance can be secured. To do this, perform a full scheduled recording by notifying the total amount of reserved recording space required, the amount of reserved recording space that is currently empty, and providing a list of recordables that can be deleted to ensure that the reserved recording space is insufficient. In addition, the user may prepare a recording space and manage recordings in advance.
