  FIG. 7 is a flowchart showing a recording limit arrival time calculation process of the recording apparatus 1 of the present invention. In the recording apparatus 1 of the present invention, when a predetermined condition set in advance is satisfied, the arrival time when the free capacity of the recording medium 2 reaches a predetermined limit value is calculated and used by a recording process based on the reservation setting. The recording limit arrival time calculation process shown to the user is started (S601). In step S601, the predetermined condition for starting the recording limit arrival time calculation process is the recording reservation process described with reference to FIG. 2, the reservation setting change process described with reference to FIG. 3, and the recording described with reference to FIG. When the recorded reservation setting is changed by processing such as reservation information deletion processing, when the normal recording processing described with reference to FIG. 5 is completed, or when information deletion processing described with reference to FIG. 6 is performed There are conditions such as when the loading detection means 15a detects that a new recording medium 2 has been inserted into the auxiliary recording means 15 of the recording apparatus 1, or when a predetermined operation is received from the operation means 19. In addition, the reservation is not only performed when the reservation setting is changed by the user's operation as in the various processes described with reference to FIGS. 2, 3 and 4, but also by the automatic processing of the recording apparatus 1 based on the electronic program guide. Even when the setting is changed, it is determined that a predetermined condition for starting the recording limit arrival time calculation process is satisfied. Further, the information deletion process described with reference to FIG. 6 shows a case where information is deleted by a user's operation. However, when information is deleted by automatic processing of the recording apparatus 1, the information is deleted based on the reservation setting. Even when it is detected that the capacity of the free area of the recording medium 2 has changed by automatic processing of the recording device 1 such as when a broadcast program recorded every week is overwritten, the recording limit arrival time calculation processing is performed. It is determined that a predetermined condition for starting is satisfied.

  As the recording limit arrival time calculation process started in step S601, the recording apparatus 1 detects the capacity of the free area of the recording medium 2 to be recorded with the video signal under the control of the control means 10 (S602), and sets the reservation. Is calculated based on the recording reservation information recorded as (S603), the detected free area capacity is compared with the calculated recording processing capacity, and the recording processing based on all the recording reservation information is performed. It is determined whether or not (S604). The capacity required for the recording process calculated in step S603 is calculated from the recording time and the recording format obtained from the recording start date and time and the recording end date and time indicated in the recording reservation information. If the recording reservation information recorded as the reservation setting includes recording reservation information indicating repetitive recording such as every Sunday from 20:00 to 21:00, the capacity required for the recording process is calculated as infinite. The

  When it is determined in step S604 that the recording process is impossible, that is, when it is determined that the capacity required for the recording process based on all the recording reservation information exceeds the capacity of the free area of the recording medium 2 (S604: NO) The recording apparatus 1 controls the control unit 10 to set the free area capacity of the recording medium 2 to a predetermined limit value, for example, 99 of the total recording capacity, based on the free area capacity of the recording medium 2 and the recording reservation information. The arrival time reaching% is calculated (S605), the calculated arrival time is recorded in the second recording means 12 (S606), the arrival time is further output (S607), and the recording limit arrival time calculation processing is terminated. The calculation of the arrival time based on the capacity of the free area and the recording reservation information in step S605 is the capacity required for the recording process calculated from the recording time and recording format determined from the recording start date and time and the recording end date and time indicated in the recording reservation information. And the free space is compared. The arrival time calculated in step S605 may be the recording start date and time of the broadcast program recorded at the time when it reaches 99% instead of the time when it actually reaches 99% of the total recording capacity. Further, the arrival time to be output may be output until the date and time or only the date may be output. Furthermore, recording reservation information related to a broadcast program recorded at the arrival time, particularly the name of the program to be recorded, may be output together with the arrival time. The arrival time output in step S607 indicates a display output from the display means 16 and / or an external output as a video signal from the signal output means 17 to be displayed on the display device.

  When it is determined in step S604 that the recording process is possible, that is, when it is determined that the recording area based on the recording reservation information does not exceed the capacity of the free area of the recording medium 2 (S604: YES). The recording apparatus 1 outputs from the display unit 16 and / or the signal output unit 17 recordable information indicating that recording based on all the recording reservation information recorded as the reservation setting is possible under the control of the control unit 10. In step S608, the recording limit arrival time calculation process is terminated.

  FIG. 8 is a flowchart showing recording reservation information output processing of the recording apparatus 1 of the present invention. When the user desires to confirm the recording reservation information recorded as the reservation setting in the recording apparatus 1, the user operates the operation unit 19 to input a recording reservation information output request for requesting output of the recording reservation information.

  The recording device 1 receives a recording reservation information output request input from the operation unit 19 under the control of the control unit 10 (S701), and extracts recording reservation information recorded in the second recording unit 12 as a reservation setting (S702). Further, the arrival time calculated before and recorded in the second recording means 12 is extracted (S703), and the arrival time is output from the display means 16 and / or the signal output means 17 together with the extracted recording reservation information (S704). ). In step S703, instead of extracting the previously calculated arrival time, the recording limit arrival time calculation process described with reference to FIG. 7 is executed, and the calculated arrival time is output together with the recording reservation information. You may do it.

  FIG. 9 is a flowchart showing arrival time automatic output processing of the recording apparatus 1 of the present invention. At the time of activation, the recording device 1 reads the current date and time indicated by the clock unit 18 under the control of the control unit 10 (S801), extracts the arrival time recorded in the second recording unit 12 (S802), and the clock unit The remaining period indicating the difference between the date and time indicated by 18 and the arrival time is calculated (S803). Note that the start time at which the arrival time automatic output process starts includes, for example, not only the time when the power switch is pressed and the start of power supply to the recording apparatus 1 but also the time when the standby state is shifted to the active state. .

  The recording apparatus 1 then compares the calculated remaining period with a predetermined period such as 3 days (72 hours), 1 week (168 hours), or the like under the control of the control unit 10 (S804), and calculates the calculated remaining period. Is equal to or shorter than the predetermined period (S804: YES), the arrival time extracted in step S802 is output from the display means 16 and / or the signal output means 17 (S805). In step S802, instead of extracting the previously calculated arrival time, the recording limit arrival time calculating process described with reference to FIG. 7 is executed, and the calculated arrival time is compared with a predetermined period. Anyway. In step S804, when the remaining period is longer than the predetermined period (S804: NO), the arrival time automatic output process is terminated.

  In the above embodiment, the recording process for recording the video signal on the recording medium has been described. However, the present invention is not limited to this, and various information such as an audio signal is recorded on the recording medium. It can be applied to recording reservations.
