  However, in the conventional technique, the margin period cannot be adjusted. For this reason, there is a demand for a recording control apparatus that can adjust the margin period.

  In order to achieve the above object, a recording control apparatus according to an aspect of the present invention calculates a margin period for recording on both the first recording medium and the second recording medium in a program period of one program. A margin period calculation unit, and when the margin period calculation unit calculates the margin period, a first period including the margin period is recorded on the first recording medium for at least a part of the program period. A recording period calculating unit that calculates the recording period and the second recording period including the margin period to be recorded on the second recording medium.

  According to the recording control apparatus having the above configuration, the margin period can be adjusted.

  For example, the margin period calculation unit may calculate the margin period based on the content of the one program.

  This makes it possible to calculate the extra period according to the content of the program to be divided.

  For example, a scene detection unit that detects a scene that satisfies a predetermined condition from the one program is provided, and the margin period calculation unit is configured to detect when the scene detection unit detects a scene that satisfies the predetermined condition. Based on the detection, the margin period may be calculated.

  As a result, it is possible to calculate the extra period according to the scene of the program to be divided.

  For example, in the calculation of the margin period performed based on the detection, the margin period calculation unit calculates the margin period with the detection time point of the scene satisfying the predetermined condition as the end point of the margin period. May be.

  As a result, the end point of the extra period can be calculated according to the scene of the program to be divided.

  For example, in the calculation of the margin period performed based on the detection, the margin period calculation unit calculates the margin period with a detection time point of a scene satisfying the predetermined condition as a start point of the margin period. May be.

  This makes it possible to calculate the start time of the extra period according to the scene of the program to be divided.

  For example, the scene satisfying the predetermined condition includes a scene including a silent section, a scene in which the screen has not changed for a predetermined time or more, a scene in which subtitle information is not updated for a predetermined time or more, and a specific character string indicating scene switching in the subtitle information May be included, and at least one of a scene including a screen that does not satisfy a predetermined luminance.

  As a result, it is possible to reduce the uncomfortable feeling that is felt by the viewer who views the reproduced program.

  For example, a recordable period acquisition unit that acquires a first recordable period in which the first recording medium can record and a second recordable period in which the second recording medium can record, and the first When the recording medium capable of continuously recording the one program does not exist among the recording medium and the second recording medium, the first recordable period and the second recording are possible. Based on the period, the one program is divided into a plurality of periods, and each of the divided periods is assigned as a recording target to either the first recording medium or the second recording medium. An allocation determination unit, wherein the allocation determination unit divides the one program into a first period and a second period following the first period. In the second period, including the initial marginal period overlapping each other, The margin period calculation unit calculates the margin period from the initial margin period, and the recording period calculation unit calculates the first recording period from the first period, The second recording period may be calculated from the second period, and the allocation determination unit may perform the division so that the number of divisions of the one program is minimized.

  Thereby, in the recording of one program using the first recording medium and the second recording medium, the number of margin periods can be minimized.

  For example, a first recordable period in which the first recording medium can record, a second recordable period in which the second recording medium can record, and a third recording medium in which the third recording medium can record. The one program is continuously recorded in the recordable period acquisition unit that acquires the recordable period, the first recording medium, the second recording medium, and the third recording medium. When there is no possible recording medium, the first recording is performed when the first recordable period and the second recordable period have a common period shorter than a predetermined time. Assigning the one program to the first recording medium as an object of recording based on a possible period, the second recordable period, and the third recordable period; A first period including a period, and the second recording medium assigned as an object to be recorded. A second period including the one common period, and a third period including the one common period and having a length equal to the predetermined period, which is allocated to the third recording medium as a recording target. And the recording period calculating unit calculates the first period as the first recording period, and calculates the second period as the second recording period, The third period may be calculated as a third recording period for recording on the third recording medium.

  As a result, when the recordable period of the first recording medium and the recordable period of the second recording medium have only a common period of a length that may not be sufficient as a margin period, It is possible to record on the recording medium for a period that can be used as a margin period.

  For example, a recordable period acquisition unit that acquires a first recordable period in which the first recording medium can record and a second recordable period in which the second recording medium can record, and recording in the past Based on the recorded program, a time period in which a scene satisfying a predetermined condition appears in the one program is estimated, the estimated time period, the first recordable period, and the second recording period Based on the recordable period, the first program is assigned to the first recording medium as a recording target, and the second period is assigned to the second recording medium as a recording target. An allocation determination unit to divide, and the allocation determination unit performs the division including an initial margin period overlapping in the first period and the second period, and the margin period calculation unit includes the initial margin period. From the above, paste The recording period calculation unit calculates the first recording period from the first period, and calculates the second recording period from the second period. May be performed.

  Thereby, it is possible to calculate the extra period according to the contents of the past program.

  Note that the present invention can be realized not only as a recording control apparatus including such a characteristic processing unit, but also as a recording control method including steps executed by the characteristic processing unit included in the recording control apparatus. Can be realized. Further, it can be realized as a program for causing a computer to function as a characteristic processing unit included in the recording control apparatus or a program for causing a computer to execute characteristic steps included in the recording control method.

Further, the allocation determination unit 13 may perform the recording based on the first recordable capacity, the second recordable capacity, and the third recordable capacity. When there is a recording medium 23 capable of continuously recording the reserved recording program, the allocation determining unit 13 allocates the entire period from the start time to the end time of the reserved recording program to the recording medium 23. The allocation determination unit 13 divides the reserved recording program into a plurality of periods and can be allocated to the plurality of recording media 23 when there is no recording medium 23 capable of continuously recording the reserved recording program. Divides the reserved recording program into a plurality of periods, and assigns each of the divided periods to a plurality of recording media 23.

The portion is divided into portions including an initial marginal period for recording overlapping each other. In the first embodiment, the length of this initial margin period is set to T1 (for example, 10 minutes) in advance.

  FIG. 3 is a schematic diagram illustrating an example of a state in which the allocation determining unit 13 allocates a period for performing scheduled recording of one reserved recording program to a plurality of recording media 23. In the example shown in FIG. 3, the reserved recording program is a one-hour program with a program start time of 13:00 and a program end time of 14:00.

  As shown in FIG. 3, any of the first recording medium 23A, the second recording medium 23B, and the third recording medium 23C cannot continuously record the reserved recording program. For this reason, the allocation determination unit 13 divides the period for recording the reserved recording program into the first initial recording period 301 (period from 13: 0 to 13:40) and the second initial recording period 302 (13:30). To 14:00), and assign them to the first recording medium 23A and the second recording medium 23B, respectively. At this time, the allocation determining unit 13 overlaps the last T1 period (10 minutes) of the first initial recording period 301 and the first T1 period (10 minutes) of the second initial recording period 302. The period for recording is divided including the initial marginal period for recording (period of 13:30 to 13:40).

  Returning to FIG. 1 again, the description of the configuration of the recording control device 10 will be continued.

  When the allocation determination unit 13 allocates a period for recording the reserved recording program, the allocation determination unit 13 indicates an initial period indicating the allocated period for each of the control units 24 included in the recording / reproducing device 20 including the allocated recording medium 23. Send allocation period information. Each control unit 24 that has received the initial allocation period information performs reserved recording for the period indicated by the initial allocation period information in the program period of the reserved recording program.

  The scene detection unit 16 detects a scene satisfying a predetermined condition from programs being recorded in the first recording / reproducing device 20A, the second recording / reproducing device 20B, and the third recording / reproducing device 20C. . In Embodiment 1, a scene that satisfies a predetermined condition is a scene that includes a silent section. The scene detection unit 16 receives a silent section detection signal transmitted from the recording unit 22 to detect a scene that satisfies a predetermined condition. Generally, in a program, there is no sound at the timing when CM is started. For this reason, the scene detection unit 16 substantially detects the scene where the CM starts from the program.

  The margin period calculation unit 17 calculates a margin period for recording on both the one recording medium 23 and the other recording medium 23 in the program period of the reserved recording program. In the first embodiment, the margin period calculation unit 17 calculates the margin period based on the contents of the reserved recording program to be recorded. More specifically, when the scene detection unit 16 detects a scene that satisfies a predetermined condition during the initial margin period, the margin period calculation unit 17 sets the detection time point of the scene based on the detection. At the end of the period, the extra period is calculated.

  FIG. 4 shows an example of how the margin period calculation unit 17 calculates the margin period for recording on both the first recording medium 23A and the second recording medium 23B in the program period of one reserved recording program. It is a schematic diagram which shows. In the example shown in FIG. 4, the period for recording one reserved recording program by the allocation determination unit 13 is the first initial recording period 301 (13: 0 to 13:40 period) and the second initial recording period. The scene detection unit 16 is divided into a recording period 302 (a period from 13:30 to 14:00) and assigned to the first recording medium 23A and the second recording medium 23B, respectively. However, this is an example when a scene including a silent section (time of 13:35) is detected in the initial marginal period (period of 13:30 to 13:40).

  As shown in FIG. 4, when the scene detection unit 16 detects a scene including a silent period, that is, a scene in which CM is substantially started, at 13:35 in the initial margin period, the margin period is calculated. The unit 17 calculates the margin period with 13:35, which is the detection point of the scene, as the end point of the margin period. That is, the margin period calculation unit 17 performs a margin period (13:30) from 13:30, which is the start point of the initial margin period, to 13:35, which is the point in time when the scene where the CM is actually started is detected. ~ 13: 35 period).

  Returning to FIG. 1 again, the description of the configuration of the recording control device 10 will be continued.

  The margin period calculation unit 17 calculates the margin period by combining the first recording medium 23A and the second recording medium 23B, the combination of the second recording medium 23B and the third recording medium 23C, and This is performed for each combination of the third recording medium 23C and the first recording medium 23A. In other words, the margin period calculation unit 17 applies both the first recording medium 23A and the second recording medium 23B from the initial margin period in the combination of the first recording medium 23A and the second recording medium 23B. The first margin period to be recorded is calculated, and the second recording medium 23B and the third recording medium 23C are selected from the initial margin periods in the combination of the second recording medium 23B and the third recording medium 23C. The second margin period to be recorded by both is calculated, and the third recording medium 23C and the first recording period are selected from the initial margin period in the combination of the third recording medium 23C and the first recording medium 23A. A third margin period for recording on both the medium 23A is calculated.

  The recording period calculation unit 18 causes the one recording medium 23 to record at least a part of the reserved recording program when the margin period calculation unit 17 calculates the margin period. The margin period is the last part of the recording period. And the other recording period including the extra period in the first part of the recording period to be recorded on the other recording medium 23. When the recording period calculating unit 18 calculates the end point of one recording period, the recording period calculating unit 18 performs the recording on the recording medium 23 with respect to the control unit 24 included in the recording / reproducing device 20 including the one recording medium 23. A recording stop signal indicating that recording is stopped is transmitted. When receiving the recording stop signal, the control unit 24 stops the recording currently being performed on the one recording medium 23. With this stop, the recording of one recording period is completed.

  In the example shown in FIG. 4, the recording period calculation unit 18 performs the first recording from the start point (13:00) of the first initial recording period 301 to the end point (13:35) of the extra period. It is calculated as the first recording period 301A (13: 0 to 13:35 period) to be recorded on the medium 23A, and from the start time (13:30) of the second initial recording period 302 to the second initial recording period 302. The period up to the end point (14:00), that is, the second initial recording period 302 itself is calculated as the second recording period (period from 13:30 to 14:00) for recording on the second recording medium 23B. To do.

  Returning to FIG. 1 again, the description of the configuration of the recording control device 10 will be continued.

  The recording period calculation unit 18 calculates the recording period for each of the first margin period, the second margin period, and the third margin period. That is, the recording period calculation unit 18 calculates the first recording period including the first margin period and the third margin period from the first period, and from the second period, The second recording period and the third margin are calculated by calculating the second recording period including the one extra period and the second extra period, and recording on the third recording medium from the third period. A third recording period including the period is calculated.

  When calculating the end point of the first recording period, the recording period calculating unit 18 transmits a recording stop signal indicating that recording currently being performed on the first recording medium 23A is stopped to the control unit 24A. . When the recording stop signal is received, the control unit 24A stops the recording currently being performed on the first recording medium 23A. Due to this stop, the recording in the first recording period ends. When the recording period calculation unit 18 calculates the end point of the second recording period, the recording period calculation unit 18 sends a recording stop signal indicating that the recording currently being performed on the second recording medium 23B is stopped to the control unit 24B. Send. When receiving the recording stop signal, the control unit 24B stops the recording currently being performed on the second recording medium 23B. Due to this stop, the recording in the second recording period ends. Further, when the recording period calculation unit 18 calculates the end point of the third recording period, the recording period calculation unit 18 sends a recording stop signal indicating that the recording currently being performed on the third recording medium 23C is stopped to the control unit 24C. Send. When the recording stop signal is received, the control unit 24C stops the recording that is currently being performed on the third recording medium 23C. Due to this stop, the recording in the third recording period ends.

  When the input / output unit 12 accepts program playback, the continuous playback unit 19 causes the control unit 24 included in the recording / playback machine 20 including the recording medium 23 that recorded the program to play back the program. Send a signal. In particular, when the input / output unit 12 accepts playback of a program that has been divided into a plurality of recording media 23 and recorded, the continuous playback unit 19 includes a recording medium 23 that records a part of the program. A reproduction signal for seamlessly reproducing the program is transmitted to each of the control units 24 included in the reproduction device 20. More specifically, the continuous playback unit 19 records the preceding first recording period portion of the program to be played back on the one recording medium 23, and follows the preceding first recording period. When the portion of the second recording period to be recorded is recorded on the other recording medium 23, the entire preceding first recording period is reproduced first, and then the preceding recording period is continued. The control unit included in the recording / reproducing device 20 including the one recording medium 23 receives a reproduction signal indicating that the subsequent second recording period portion is reproduced from the last scene portion of the first recording period. 24 and the control unit 24 included in the recording / reproducing machine 20 including the other one recording medium 23. Then, each control unit 24 that has received the playback signal reads the recorded portion of the program recorded on the recording medium 23 included in the self-recording / playback device 20 so that the program to be played is seamlessly played back. Let it play. In this case, it is desirable that the program to be reproduced is displayed on one display device. For example, when a display is connected to the first recording / reproducing device 20A, a program to be reproduced may be displayed on the display. For example, when the playback unit 25A includes a display, a program to be played back may be displayed on the display. For example, when the input / output unit 12 includes a touch panel, a program to be reproduced may be displayed on the touch panel.

  FIG. 5 shows that one program has a preceding first recording period 301A (13:00 to 13:35) and a second recording period 302A (13:30 to 14:00) that follows. When the portion of the first recording period 301A is recorded on the first recording medium 23A and the portion of the second recording period 302A is recorded on the second recording medium 23B. It is a schematic diagram which shows an example of a mode that a program is reproduced | regenerated seamlessly. As shown in FIG. 5, in the first program, the entire first recording period 301A is first reproduced, and then, in the second recording period 302A, the last one of the first recording period is continuously played. From the scene (at 13:35) to the last scene of the second recording period 302 is reproduced.

  Returning to FIG. 1 again, the description of the configuration of the recording control device 10 will be continued.

  The control unit 11 includes an input / output unit 12, an allocation determination unit 13, a recordable period acquisition unit 14, a communication unit 15, a scene detection unit 16, a margin period calculation unit 17, a recording period calculation unit 18, The continuous playback unit 19 is controlled. The control unit 11 may be realized by, for example, dedicated hardware, or may be realized by, for example, the recording control device 10 including a processor and a memory, and the processor executing a program stored in the memory. .

[Discussion]
According to the recording control apparatus 10 configured as described above, when a program divided into a plurality of recording media and recorded by the recording control apparatus 10 is seamlessly reproduced, the silent section is detected when the recording medium 23 is switched during reproduction. It is performed at the timing, that is, the timing at which the CM is substantially started. For this reason, even if the viewer who views this program changes the recording medium 23 during playback, for example, the video is disturbed, the sense of incongruity associated with this program is reduced. Further, according to the recording control device 10, the margin period can be adjusted to a period shorter than a predetermined initial margin period T1. Therefore, the recording system 1 can efficiently use the storage capacity of the first recording medium 23A, the second recording medium 23B, and / or the third recording medium 23C.

(Embodiment 2)
Here, a recording system according to the second embodiment in which a part of the configuration is changed from the recording system 1 according to the first embodiment will be described.

[Recording system configuration]
FIG. 6 is a block diagram showing the configuration of the recording system 1A according to the second embodiment.

  As shown in FIG. 6, in the recording system 1A, the recording unit 22A is changed to the recording unit 222A, the recording unit 22B is changed to the recording unit 222B, and the recording unit 22C is changed from the recording system 1 according to the first embodiment. The recording unit 222C is changed, the scene detection unit 16 is changed to the scene detection unit 162, and the margin period calculation unit 17 is changed to the margin period calculation unit 172. With these changes, the first recorder / player 20A is changed to the first recorder / player 202A, the second recorder / player 20B is changed to the second recorder / player 202B, and the third recorder / player is changed. The playback device 20C is changed to the third recording / playback device 202C, and the recording control device 10 is changed to the recording control device 102.

  Hereinafter, when there is no need to explicitly distinguish between the recording unit 222A, the recording unit 222B, and the recording unit 222C, the recording unit 222A, the recording unit 222B, and the recording unit 222C are referred to as “ It may also be called “recording unit 222”.

  Similar to the recording unit 22 according to the first embodiment, the recording unit 222 detects a silent section from the program being recorded. Then, the recording unit 222 outputs a silent section detection signal to the scene detection unit 162. Furthermore, the recording unit 222 also calls a scene where the screen has not changed for a predetermined time (hereinafter also referred to as “first scene”) and a scene in which the caption information is not updated for a predetermined time (hereinafter also referred to as “second scene”). ), A scene in which the subtitle information includes a specific character string indicating scene switching (hereinafter, also referred to as a “third scene”), and a scene including a screen that does not satisfy a predetermined luminance (hereinafter, “ Also called “fourth scene”). When these scenes are detected, the recording unit 222 transmits a specific scene detection signal indicating that a specific scene has been detected, to the scene detection unit 162 of the recording control apparatus 102. The first scene to the fourth scene are all uncomfortable that a viewer who views the program remembers for the program even if the video is disturbed at the timing of the scene during the playback of the program. This corresponds to a scene with relatively few. In the recording unit 222, even if a viewer who watches a program other than the first to fourth scenes, for example, the video is disturbed, the viewer who views the program learns about this program. A scene with relatively little discomfort may be detected, and a specific scene detection signal indicating that a specific scene has been detected may be transmitted to the scene detection unit 162.

  The scene detection unit 162 is a scene that satisfies the first predetermined condition from programs being recorded in the first recording / reproducing device 202A, the second recording / reproducing device 202B, and the third recording / reproducing device 202C. And a scene satisfying the second predetermined condition are detected. In the second embodiment, the scene that satisfies the first predetermined condition is a scene including a silent section, and the scenes that satisfy the second predetermined condition are the first scene to the fourth scene. The scene detection unit 162 receives the silent section detection signal transmitted from the recording unit 222, detects a scene that satisfies the first predetermined condition, and receives the specific scene detection signal transmitted from the recording unit 222. Thus, a scene that satisfies the second predetermined condition is detected.

  The margin period calculation unit 172 calculates a margin period for recording on one recording medium 23 and the other recording medium 23 in the program period of the reserved recording program. In the second embodiment, the margin period calculation unit 172 calculates the margin period based on the contents of the reserved recording program to be recorded. More specifically, the margin period calculation unit 172 determines that the scene detection unit 162 detects a scene that satisfies the first predetermined condition during the initial margin period, or a scene that satisfies the second predetermined condition. Is detected, the margin period is calculated based on the detection of the scene as the end point of the margin period.

[Discussion]
The recording control apparatus 10 according to Embodiment 1 is a configuration example in which the timing at which CM is started substantially becomes the end point of the margin period during the initial margin period. On the other hand, in the recording control apparatus 102 configured as described above, in addition to the fact that the timing at which the CM is started substantially becomes the end point of the margin period during the initial margin period, the first period is the first margin period. The timing when the scenes No. 4 to No. 4 are started is also the end point of the margin period. For this reason, the recording system 1A that uses the recording control apparatus 102 is further more than the first recording medium 23A, the second recording medium 23B, and / or the third recording than the recording system 1 according to the first embodiment. The storage capacity of the medium 23C can be used efficiently.

(Embodiment 3)
Here, a recording system according to the third embodiment, in which a part of the configuration is changed from the recording system 1 according to the first embodiment, will be described.

[Recording system configuration]
FIG. 7 is a block diagram showing a configuration of a recording system 1B according to the third embodiment.

  As shown in FIG. 7, in the recording system 1B, the assignment determining unit 13 is changed to the assignment determining unit 133 from the recording system 1 according to the first embodiment. With this change, the recording control device 10 is changed to the recording control device 103.

  The allocation determining unit 133 includes a first recordable period, a second recordable period, and a third recordable period acquired by the recordable period acquiring unit 14 from the allocation determining unit 13 according to Embodiment 1. In addition to the period, the program is further divided based on the contents of the program recorded in the past.

  When dividing one program, the allocation determining unit 133 inquires each control unit 24 included in the recording system 1B about the presence or absence of a program related to the one program among the programs recorded in the past. In the third embodiment, the related program refers to a program having the same broadcast time zone and at least a part of the program name having the same name. For example, an information program with the same name that is broadcast as a band program every weekday, a drama program with the same name that is broadcast every week at the same time zone, and the like correspond to related programs. When one or more related programs have been recorded, the assignment determining unit 133 receives the related program from the control unit 24 included in the recording / reproducing device 20 including the recording medium 23 on which the related programs are recorded. In each case, silent section time information indicating the time when the silent section is detected is acquired. Then, the allocation determination unit 133 uses the acquired silent section time information to insert a silent section in one program to be divided (hereinafter also referred to as “estimated silent section time period”). Is estimated. The allocation determining unit 133 calculates an appropriate length of the margin period (hereinafter also referred to as “margin length”) based on the estimated silent section time zone. For example, the allocation determination unit 133 may calculate the margin length as 5 minutes when the estimated silent section time zone is within a width of 3 minutes. In addition to the first recordable period, the second recordable period, and the third recordable period, the allocation determination unit 133 adds the estimated silent period time zone, the margin length, and the first recording period. Based on the available capacity, the second recordable capacity, and the third recordable capacity, it is determined which part of the target program is to be recorded on which recording medium 23. For example, the assignment determining unit 133 may divide the program so that the program part having the shortest recording period is recorded on the recording medium 23 having the smallest recordable capacity.

[Discussion]
According to the recording control apparatus 103 configured as described above, in a related program recorded in the past, which of the programs to be recorded is determined based on the timing at which a silent section is detected, that is, the timing at which CM is actually started. The recording medium 23 on which the part is recorded is determined. For this reason, the recording system 1 </ b> B can reduce the possibility that the recording of the program to be recorded is stopped due to a shortage of the capacity of any recording medium 23.

(Embodiment 4)
Here, a recording system according to the fourth embodiment, in which a part of the configuration is changed from the recording system 1 according to the first embodiment, will be described.

[Recording system configuration]
FIG. 8 is a block diagram showing a configuration of a recording system 1C according to the fourth embodiment.

  As shown in FIG. 8, in the recording system 1 </ b> C, the allocation determining unit 13 is changed to the allocation determining unit 134 from the recording system 1 according to Embodiment 1, and the margin period calculating unit 17 is changed to the margin period calculating unit 174. Thus, the recording period calculation unit 18 is changed to the recording period calculation unit 184, and the continuous playback unit 19 is changed to the continuous playback unit 194. In addition, with these changes, the recording control device 10 is changed to the recording control device 104.

  The allocation determination unit 134 allocates a period for recording a reserved recording program, similarly to the allocation determination unit 13 according to the first embodiment. Then, the allocation determining unit 134 transmits first initial allocation period information indicating the allocated period to the control unit 24 included in the recording / reproducing device 20 including the recording medium 23 to which the first period is allocated, Second initial allocation period information indicating the allocated period is transmitted to each of the control units 24 included in the recording / reproducing device 20 including the recording medium 23 to which the period other than the first period is allocated. Each control unit 24 that has received the first initial allocation period information performs scheduled recording for the period indicated by the first initial allocation period information in the program period of the reserved recording program. In addition, each control unit 24 that has received the second initial allocation period information sets the reserved recording for the period indicated by the second initial allocation period information in the program period of the reserved recording program to the standby state. Here, the standby state of the reserved recording means that the recording start is suspended without starting the recording even when the time for starting the reserved recording is reached, and a signal to cancel the standby state is received after the reserved recording start time. This means a state in which the hold is released at the time of reception and recording is performed from the time of reception until the end of reserved recording.

  The margin period calculation unit 174 records on both the one recording medium 23 and the other one recording medium 23 by a calculation method different from the calculation of the margin period performed by the margin period calculation unit 17 according to the first embodiment. Calculate the margin period. That is, when the scene detection unit 16 detects a scene that satisfies a predetermined condition during the initial margin period, the margin period calculation unit 174 determines the detection time of the scene based on the detection. As a result, the marginal period is calculated.

  FIG. 9 shows an example in which the margin period calculation unit 174 calculates a margin period for recording on both the first recording medium 23A and the second recording medium 23B in the program period of one reserved recording program. It is a schematic diagram which shows. In the example shown in FIG. 9, the period for recording one reserved recording program by the allocation determining unit 134 is the first initial recording period 301 (13: 0 to 13:40 period) and the second initial recording period. The scene detection unit 16 is divided into a recording period 302 (a period from 13:30 to 14:00) and assigned to the first recording medium 23A and the second recording medium 23B, respectively. However, this is an example when a scene including a silent section (time of 13:35) is detected in the initial marginal period (period of 13:30 to 13:40).

  As shown in FIG. 9, when the scene detection unit 16 detects a scene including a silent period, that is, a scene in which CM is substantially started, at 13:35 in the initial margin period, the margin period is calculated. The unit 174 calculates the margin period using 13:35, which is the detection point of the scene, as the beginning point of the margin period. That is, the margin period calculation unit 174 performs a margin period (13:35) from 13:35, which is a point at which a scene where CM is actually started, is detected to 13:40, which is the end point of the initial margin period. ~ 13: 40 period).

  Returning to FIG. 8 again, the description of the configuration of the recording control device 104 will be continued.

  Similar to the recording period calculation unit 18 according to the first embodiment, the recording period calculation unit 184 performs one recording for at least a part of the reserved recording program when the margin period calculation unit 174 calculates the margin period. One recording period including a margin period in the last part of the recording period to be recorded on the medium 23 and another one recording including a margin period in the first part of the recording period to be recorded on the other recording medium 23 Calculate the period. Then, when the recording period calculation unit 184 calculates one recording period and another recording period, the recording period calculation unit 184 schedules recording to the control unit 24 included in the recording / reproducing device 20 including the other recording medium 23. A standby release signal indicating that the standby state is to be released is transmitted. The control unit 24 that has received the standby cancellation signal cancels the standby state of the reserved recording. By canceling the standby state of the reserved recording, recording in another recording period is started.

  In the example shown in FIG. 9, the recording period calculation unit 184 includes a period from the start point (13:00) of the first initial recording period 301 to the end point (13:40) of the first initial recording period 301, That is, the first initial recording period 301 itself is calculated as a first recording period (13:00 to 13:40) for recording on the first recording medium 23A, and the start point of the extra period (13:35). ) To the end point (14:00) of the second initial recording period 302 is calculated as the second recording period 302B (13:35 to 14:00) recorded on the second recording medium 23B. To do.

  Returning to FIG. 8 again, the description of the configuration of the recording control device 104 will be continued.

  When the input / output unit 12 accepts program playback, the continuous playback unit 194 causes the control unit 24 included in the recording / playback machine 20 including the recording medium 23 that recorded the program to play back the program. Send a signal. In particular, when the input / output unit 12 accepts playback of a program that has been divided into a plurality of recording media 23 and recorded, the continuous playback unit 194 includes a recording medium 23 that records a part of the program. A reproduction signal for seamlessly reproducing the program is transmitted to each of the control units 24 included in the reproduction device 20. More specifically, the continuous playback unit 194 records the part of the first recording period that precedes the program to be played back on one recording medium 23, and follows the preceding first recording period. When the part of the second recording period to be recorded is recorded on the other recording medium 23, the first part of the second recording period that follows from the first part of the preceding first recording period is first performed. The recording / reproducing apparatus 20 including one recording medium 23 includes a reproduction signal indicating that the entire second recording period to be reproduced is reproduced continuously after the reproduction. To the control unit 24 and the control unit 24 included in the recording / reproducing machine 20 including the other one recording medium 23. Then, each control unit 24 that has received the playback signal reads the recorded portion of the program recorded on the recording medium 23 included in the self-recording / playback device 20 so that the program to be played is seamlessly played back. Let it play.

  FIG. 10 shows that one program includes a preceding first recording period 301B (13:00 to 13:40 period) and a second recording period 302B (13:35 to 14:00 period) that follows. When the portion of the first recording period 301B is recorded on the first recording medium 23A and the portion of the second recording period 302B is recorded on the second recording medium 23B, It is a schematic diagram which shows an example of a mode that a program is reproduced | regenerated seamlessly. As shown in FIG. 10, one program is first played from the first scene portion of the first recording period 301B to the first scene (at 13:35) of the second recording period 302B. Next, the entire second recording period 302B is reproduced continuously.

[Discussion]
According to the recording control apparatus 104 configured as described above, in the same way as the recording control apparatus 10 according to the first embodiment, when a program divided and recorded on a plurality of recording media by the recording control apparatus 104 is seamlessly reproduced, The recording medium 23 is switched at the timing when the silent section is detected, that is, at the timing when the CM is substantially started. For this reason, even if the viewer who views this program changes the recording medium 23 during playback, for example, the video is disturbed, the sense of incongruity associated with this program is reduced. Further, according to the recording control apparatus 104, the margin period can be adjusted to a period shorter than a predetermined initial margin period T1, similarly to the recording control apparatus 10 according to the first embodiment. Therefore, the recording system 1C, like the recording system 1 according to the first embodiment, has the storage capacity of the first recording medium 23A, the second recording medium 23B, and / or the third recording medium 23C. It can be used efficiently.

(Embodiment 5)
Here, the recording system 1 divides one reserved recording program into three or more recording periods and divides it into a first recording medium 23A, a second recording medium 23B, and a third recording medium 23C. A specific case of recording (hereinafter also referred to as “specific case”) will be described.

  FIG. 11 shows the relationship between the reserved recording program, the recordable period in the first recording medium 23A, the recordable period in the second recording medium 23B, and the recordable period in the third recording medium 23C in a specific case. It is a schematic diagram which shows.

  As can be seen from FIG. 11, in this specific case, the reserved recording program cannot be recorded unless the reserved recording program is divided into three or more recording periods.

  FIG. 12 shows an example of a state in which a reserved recording program is divided into three recording periods and recorded on the first recording medium 23A, the second recording medium 23B, and the third recording medium 23C in a specific case. It is a schematic diagram which shows.

  FIG. 13 shows an example of a state in which a scheduled recording program is divided into four recording periods and recorded on the first recording medium 23A, the second recording medium 23B, and the third recording medium 23C in a specific case. It is a schematic diagram which shows.

  As is clear from a comparison between FIG. 12 and FIG. 13, the recording of the reserved recording program by dividing it into three recording periods is more effective than the recording by dividing it into four recording periods. The total recording period of the recording medium 23A, the second recording medium 23B, and the third recording medium 23C is shortened by the margin period C. Similarly, recording a scheduled recording program by dividing it into three recording periods is more effective than dividing the first recording medium 23A and the second recording medium 23B by dividing the recording program into five or more recording periods. As a result, the total recording period with the third recording medium 23C is shortened. That is, in the specific case, the scheduled recording program is divided into three recording periods instead of being divided into four or more recording periods, thereby recording the first recording medium 23A and the second recording program. The total recording period of the recording medium 23B and the third recording medium 23C can be minimized.

  As described above in the first embodiment, when there are a plurality of reservation recording program division methods, the assignment determination unit 13 assigns a period for performing reservation recording so that the number of divisions is minimized. That is, in the specific case, the allocation determination unit 13 divides the reserved recording program into three recording periods as shown in FIG. Therefore, in the specific case, the recording system 1 can shorten the total recording period with the first recording medium 23A, the second recording medium 23B, and the third recording medium 23C.

(Embodiment 6)
Here, a recording system according to the sixth embodiment, in which a part of the configuration is changed from the recording system 1 according to the first embodiment, will be described.

[Recording system configuration]
FIG. 14 is a block diagram showing a configuration of a recording system 1E according to the sixth embodiment.

  As shown in FIG. 14, in the recording system 1E, from the recording system 1 according to the first embodiment, the assignment determining unit 13 is changed to the assignment determining unit 136, and the recording period calculating unit 18 is changed to the recording period calculating unit 186. Has been. In addition, with these changes, the recording control device 10 is changed to the recording control device 106.

  The allocation determining unit 136 has one common period in the one recording medium 23 and the other one recording medium 23 from the allocation determining unit 13 according to Embodiment 1, and the one common The division method of the reserved recording program to be performed when the period is shorter than the initial margin period T1 is changed. That is, the allocation determining unit 136 has a common period for one recording medium 23 and another recording medium 23, and the one common period is shorter than the initial margin period T1. In addition, a first period in which the reserved recording program is assigned to one recording medium 23 as a recording target, a second period in which the reserved recording program is assigned as a recording target to another recording medium, and another further recording medium Are divided into a third period allocated as a recording target. In this division, the first period, the second period, and the third period include the one common period, and the length of the third period becomes the initial margin period T1. Divide as follows.

  FIG. 15 is a schematic diagram illustrating an example of a state in which the allocation determination unit 136 allocates a period for performing scheduled recording of one reserved recording program to a plurality of recording media 23.

  As shown in FIG. 15, in this example, the reserved recording program cannot be recorded unless the reserved recording program is divided into three or more recording periods. For this reason, the allocation determination unit 136 divides the reserved recording program into three recording periods. On the other hand, the common period (T3) of the recordable period of the first recording medium 23A and the recordable period of the second recording medium 23B is 5 minutes shorter than the initial margin period T1 (here, 10 minutes). There is only. For these reasons, the allocation determination unit 136 includes the first period 305A for assigning the reserved recording program as a recording target to the first recording medium 23A including the common period, and the first period including the common period. A second period 305B allocated as a recording target to the second recording medium 23B and a third period allocated to the third recording medium 23C as a recording target, including the common period and having a period length of T1 Divide into 305C.

  Returning to FIG. 14 again, the description of the configuration of the recording control device 106 will be continued.

  The recording period calculation unit 186 has one common period in the one recording medium 23 and the other recording medium 23 from the recording period calculation unit 18 according to the first embodiment, and the one The calculation method of the recording period performed when the common period is shorter than the initial marginal period T1 is changed. That is, the recording period calculation unit 186 has one common period in one recording medium 23 and the other one recording medium 23, and the one common period is shorter than the initial margin period T1. In this case, the allocation determination unit 136 assigns a reserved recording program to one recording medium 23 as a recording target, and a second period allocates the other recording medium 23 as a recording target. When divided into a third period allocated as a recording target to another recording medium 23, the first period is calculated as a first recording period for recording on one recording medium 23, and the second period is calculated. The period is calculated as the second recording period for recording on the other recording medium 23, and the third period is calculated as the third recording period for recording on the other recording medium 23.
