(Operation of recording and playback system)
The operation of the present invention will be described below with reference to the flowcharts of FIGS. 8 and 9 with reference to FIGS. It is assumed that the recording / reproducing apparatus 3 has just been purchased and reserves recording for the first time.

  The user operates a remote controller (not shown) or the input unit 31 of the recording / playback apparatus 3 to make a recording reservation. Based on the input information from the input unit 31, the control unit 33 activates the recording reservation registration system in the recording reservation unit 400, and transmits instruction information so that the recording reservation setting screen is displayed on the monitor 2 from the output unit 37. To do.

  The user operates the remote controller or the input unit 31 while looking at the recording reservation setting screen displayed on the display screen 20 of the monitor 2, and as an example, from “Reservation No. 1” of the reservation number 3420 in FIG. No. 3 "recording reservation is registered (S1).

  The control unit 33 transmits the input information from the input unit 31 to the recording reservation unit 400, and the recording reservation unit 400 creates the recording reservation information 342 based on the input information, and based on the recording reservation information 342. The remaining disk capacity information 343 is generated. At this time, it is assumed that the disk consumption capacity 3433 and the remaining disk capacity 3434 are not input.

  The control unit 33 stores the recording reservation information 342 in the storage unit 34. Further, the control unit 33 transmits the remaining disk capacity 3434 to the remaining capacity calculation unit 401.

  Here, the remaining capacity calculation unit 401 calculates the disk consumption capacity 3433 and the remaining disk capacity 3434 by the following method.

The capacity V of the recording data 341 of the program reserved for recording can be calculated by the product of the bit rate and time. The bit rate varies depending on the recording mode 3424, and represents the number of bits that can be transmitted per second in the unit of bps. A bit is a minimum unit of data handled by a computer, and is represented by a binary number. One bit can represent two states.

Assuming that the bit rate of the recording mode 3424 (in SP mode) is 8 Mbps, the capacity V ₁ required for recording a program for one hour is calculated from (1) as follows.

The capacity of the HDD serving as the storage unit 34 is generally represented by bytes. Since 1 bit is generally defined as 8 bytes, 8 Mbps is 1 Mbyte. Further, since one hour is 3600 seconds, the capacity V ₁ necessary for recording a one-hour program can be calculated by substituting them into (2).

From (3), V ₁ is 3600 Mbytes. Since the capacity of the HDD is expressed in Gbytes, 1 Mbyte is 2 ⁻¹⁰ Gbytes. Therefore, when this is calculated, V ₁ becomes approximately 3.5 Gbytes. Therefore, the capacity V ₁ required for recording an hourly program, that is, the disk consumption capacity 3433 is approximately 3.5 Gbytes when the bit rate of the recording mode 3424 is 8 Mbps.

  The remaining capacity calculation unit 401 repeats the above calculation as an example up to one month ahead for the reservation 3430 in FIG. 5 to calculate the disk consumption capacity 3433.

  Further, the remaining capacity calculation unit 401 calculates the difference between the remaining capacity of the storage unit 34 corresponding to the reservation 3430 and the disk consumption capacity 3433 (S2), calculates the remaining disk capacity 3434, and updates the remaining disk capacity information 343. And stored in the storage unit 34.

  The remaining capacity calculation unit 401 detects from the disk remaining capacity information 343 a reservation 3430 that cannot be reserved for recording, and calculates the date and time when the disk remaining capacity 3434 becomes zero as “2006/8/29 22:21” ( S3).

  The control unit 33 creates the remaining disk capacity display information based on the remaining disk capacity information 343 and the detected date and time of zero, and transmits the disk remaining capacity display information to the monitor 2 from the output unit 37. As shown in FIG. 6, the recording reservation that is not executed is displayed with diagonal lines (S4), and the remaining disk capacity display 60 is also displayed at the same time.

  Recording reservations that cannot be executed due to a shortage of the remaining disk capacity 3434 are displayed as hatched or reversed as shown in FIG. 6, so that the user can easily determine whether the remaining disk capacity 3434 is insufficient.

  When the user adds a new recording reservation (S5; Yes), the remaining capacity calculation unit 401 returns to step 2 to calculate the capacity of the recording data 341 of the added recording reservation program.

  In step 5, when the user has not added a new recording reservation (S5; No), step 5 is confirmed until the recording reservation registration system is terminated (S6; No). When the registration system is terminated (S6; Yes), the operation is terminated.

(Register due date for reporting insufficient disk space)
The user operates the remote controller or the input unit 31 of the recording / reproducing apparatus 3 to register the disk remaining capacity shortage reporting date as a timing (S10).

  The control unit 33 creates report date information 344 based on the input signal from the input unit 31 and stores it in the storage unit 34.

  When the disk shortage shortage report date has come (S11), the control unit 33 sets the disk remaining based on the disk remaining capacity information 343 and the detected date and time of zero even if the user is watching the program. The remaining capacity display information is created and output to the monitor 2 from the output unit 37. The monitor 2 displays the disk remaining capacity display 60 on the display screen 20 (S12), or the user confirms and erases the display, or The display is continued until the recording / reproducing apparatus 3 is turned off.

  Here, the monitor 2 displays the remaining disk capacity display 60 on the display screen 20. However, the control unit 33 creates graph information based on the remaining disk capacity information 343, and displays the graph and the remaining disk capacity shown in FIG. The capacity display 60 may be displayed on the display screen 20.

  By viewing the graph shown in FIG. 7 and the remaining disk capacity display 60, the user can more clearly understand the change in the remaining disk capacity, and can avoid non-execution of recording reservation due to insufficient capacity.

  In the present embodiment, the remaining disk capacity display 60 is displayed on the display screen 20, but it may be displayed on the information display unit 36 of the recording / playback apparatus 3, but is not limited thereto. Further, the control unit 33 displays the remaining disk capacity display 60 on the display screen 20 when the disk remaining capacity shortage reporting date comes. However, only the graph of FIG. 7 may be displayed, or which one is displayed. It may be possible for the user to select, but the present invention is not limited to this. Further, the user may be notified of the date and time detected as zero using e-mail or the like.

(Effect of this embodiment)
