(Embodiment 1)
Hereinafter, Embodiment 1 will be described with reference to FIGS.

[1-1. Constitution]
FIG. 1 is a block diagram illustrating a configuration of a program recording / playback device according to the present disclosure. As shown in FIG. 1, the program recording / reproducing apparatus 100 according to the present disclosure is connected via a cable to an antenna 108 for receiving a program. The program recording / reproducing apparatus 100 is connected to the display apparatus 200 via a communication cable. The display device 200 includes a display unit 202 that displays information received from the program recording / reproducing device 100 as an image, and a communication interface 201 to which a communication cable is connected. The program recording / playback apparatus 100 includes a storage unit 101, a tuner 102, a recording unit 103, a playback unit 104, a control unit 105, a communication interface 106, and an operation unit 107.

  The program recording / reproducing apparatus 100 has a full recording function that can record a plurality of broadcasted programs without receiving an instruction from an operator. For example, the program recording / reproducing apparatus 100 is set in advance to record a plurality of channels in all programs broadcasted in one day. That is, the program recording / reproducing apparatus 100 does not issue an instruction for recording setting, except for an operator's instruction to turn on / off the power of the program recording / reproducing apparatus 100 or to use the full recording function. Is set in advance so that recording is performed. The operator plays and watches the recorded program.

  The storage unit 101 stores the program sent from the recording unit 103. The storage unit 101 includes, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), and the like.

  The tuner 102 receives and demodulates the program received by the antenna 108 for each channel.

  The recording unit 103 determines a program to be stored in the storage unit 101 according to a method specified in advance among the programs received by the tuner 102. The recording unit 103 is realized by, for example, a CPU (Central Processing Unit) and a control program stored in the storage unit 101. Here, the instructed method is a method in which the recording unit 103 selects a program to be recorded.

  The reproduction unit 104 reads the program selected by the operator from the storage unit 101 and reproduces the program. The reproduction unit 104 is realized by, for example, a CPU and a control program stored in the storage unit 101. Further, the reproducing unit 104 instructs the storage unit 101 to store the reproduced program and the reproduction time of the program.

  The communication interface 106 is a communication adapter for connecting the program recording / reproducing device 100 and a communication cable.

  The operation unit 107 is a device that receives an operator's instruction. The operation unit 107 is not particularly limited as long as it can receive an operator's instruction. The operation unit 107 may be, for example, a remote control receiver or a touch panel.

  The control unit 105 is a processing unit that performs statistical analysis on the program reproduced by the reproduction unit 104, and generates and outputs an image indicating the result of the statistical analysis. The control unit 105 is realized by, for example, a CPU and a control program stored in the storage unit 101. Further, the control unit 105 receives an instruction from the operation unit 107 and issues the instruction received from the operation unit 107 to the reproduction unit 104, the recording unit 103, and the like.

  Next, the statistical analysis performed by the control unit 105 will be described.

  The control unit 105 performs a statistical analysis of a reproduction pattern for each time period of the program reproduced by the operator. The statistical analysis calculates a reproduction pattern for each time period, which is a distribution of the number of reproduction programs for each broadcasting time period in one day of a program reproduced by the reproduction unit 104 in a predetermined period. The time zone is a time from a certain time T1 to a certain time T2 in a preset day. The broadcast time zone is a time zone in which a program is stored in the storage unit 101. The analysis time zone used for the statistical analysis may be set arbitrarily and is not particularly limited. For example, when the analysis time zone is set every hour, it is assumed that a program broadcast from 19:10 to 19:40 is broadcast during the analysis time zone from 19:00 to 20:00. In the case where the program is broadcasted through a plurality of analysis time zones, the broadcast start time of the program may be the broadcast time zone, or all the time zones in which the program was broadcast may be the broadcast time zones, and particularly limited. Not done.

  Further, the control unit 105 performs at least one of increasing the total number of recording days for programs that can be stored in the storage unit 101 and increasing the image quality at the time of recording based on the calculated time-zone-based reproduction pattern. Determine the recording mode. Further, the control unit 105 generates and outputs a recommended image indicating the determined recording mode. When acquiring an instruction to select an output recommended image from the operator, the control unit 105 controls the recording unit 103 so that the recording unit 103 operates in the recording mode indicated by the recommended image. In order to increase the total number of recording days, the control unit 105 may reduce the total time zone for recording in one day, or may reduce the image quality at the time of recording.

  Further, the control unit 105 analyzes the coverage ratio of the selected total time zone. Here, when the total time zone recorded in a day is reduced, the cover rate is the total time before the reduction of the cumulative playback time of all programs reproduced by the playback unit 104 in the reduced total time zone. This is the ratio of the total playing time of all programs played by the playing unit 104 in the band. The control unit 105 controls the recording unit to reduce the total time zone to be recorded in one day when the coverage is equal to or more than the predetermined value, and to reduce the image quality of the recorded program when the coverage is less than the predetermined value. 103 is controlled.

[1-2. motion]
The operation of the program recording / reproducing apparatus 100 configured as described above will be described below.

  The program recording / reproducing apparatus 100 performs each operation of statistical analysis of a program reproduced by an operator, generation and output of a statistical analysis result image and a recommended image, and generation and output of a statistical analysis result image for each predetermined period. Do. Hereinafter, each operation will be described in detail.

[1-2-1. Statistical analysis of programs played by operators]
Next, with reference to FIGS. 2 to 5, a method of analyzing a reproduction pattern for each time zone of the operator will be described.

  FIG. 2 is a flowchart showing a procedure of statistical analysis on a broadcast time slot of a program reproduced by an operator according to the first embodiment.

  First, the program recording / reproducing apparatus 100 starts recording a program. Since there is a limit to the data capacity that can be stored in the storage unit 101, when the capacity has reached the limit, old programs are deleted and new programs are stored. The maximum number of recordable days that can be stored in the storage unit 101 is the total number of recording days. The operator plays and watches the program stored in the storage unit 101. At this time, the reproduction unit 104 issues an instruction to store the program reproduced by the operator in the storage unit 101.

  The operator uses the program recording / reproducing device 100 to reproduce and view the program stored in the storage unit 101. The control unit 105 acquires, from the storage unit 101, the number of programs reproduced for each broadcast time period reproduced by the operator, and analyzes the reproduction pattern for each time period (S100). Note that a condition may be set so that the control unit 105 determines that the program has been reproduced by the operator. For example, the condition may be set to a case where reproduction is performed for 30 seconds or more, or the condition may be set to a case where reproduction is performed for 60 seconds or more. Next, the control unit 105 calculates a score value for each analysis time zone by adding the number of programs reproduced by the operator and an offset value described later. The offset value is a value set in advance for each analysis time zone.

  Next, the control unit 105 selects an analysis time period in which the acquired score value for each analysis time period is the largest (S101). Next, the control unit 105 analyzes the coverage rate in the selected analysis time zone (S102). Next, the control unit 105 determines whether the calculated coverage is equal to or higher than a predetermined ratio (S103). The predetermined ratio may be any value, for example, set to 90%. The operator sets the analysis time zone in advance, for example, every hour. When the total time zone for recording in the current recording mode is 24 hours, the total time zone for calculating the coverage is not particularly limited, but is set to, for example, 16 hours.

  First, the analysis time zone in which the total score value of the acquired programs for each analysis time zone is the largest is selected. For example, suppose that the total of the score values is highest for 16 hours from 7:00 to 23:00. At this time, 16 hours from 7:00 to 23:00 is the total time zone in which the coverage is calculated. The control unit 105 determines whether or not the ratio of the total reproduction time of 24 hours from 0:00 to 24:00 with respect to the total reproduction time of 16 hours from 7:00 to 23:00, that is, the cover rate is 90% or more. When it is determined that the coverage is 90% or more, the control unit 105 sets the total time zone of 16 hours from 7:00 to 23:00 as the total time zone of the recommended recording mode.

  In addition, the total time zone for calculating the coverage may be arbitrarily set as described above, and is not particularly limited. The total time zone for calculating the coverage may be set according to the current total time zone to be recorded. For example, if the current total time zone to be recorded is from 21 hours to 24 hours, the total time zone for calculating the coverage may be set to 16 hours. In addition, when the current total time zone for recording is 15 hours to 20 hours, the total time zone for calculating the coverage may be set to 12 hours. In addition, when the current total time zone to be recorded is 10 hours to 14 hours, the total time zone for calculating the coverage may be set to 8 hours. In addition, when the current total time zone to be recorded is 7 hours to 9 hours, the total time zone for calculating the coverage may be set to 6 hours. When the total time zone to be currently recorded is 6 hours or less, the recording mode for reducing the total time zone from the current recording mode need not be set as the recommended recording mode.

  In addition, one or a plurality of recording time zones may be set, and there is no particular limitation. For example, a plurality of time zones for recording may be set, such as a combination of an arbitrary two-hour time zone and an arbitrary 14-hour time zone. When a plurality of time zones to be recorded are set, a combination that maximizes the total score value of each time zone is selected as the time zone to be recorded. When there are a plurality of patterns in which the total of the score values is maximum, for example, a time zone in which a pattern having a wide time zone per one may be maximum may be selected.

  If the coverage is less than the predetermined value, the control unit 105 determines that the recording mode in which the total number of recording days is increased by reducing the image quality at the time of recording is recommended (S104). When the coverage is equal to or more than the predetermined value, the control unit 105 instructs the recording unit 103 to record the selected time zone. In addition, the control unit 105 determines that two recording modes are recommended, that is, a recording mode in which the quality of the recorded image is higher than the current setting and a recording mode in which the quality of the recorded image is not changed from the current setting (S105).

  The method for determining the image quality may be set arbitrarily and is not particularly limited. For example, when improving the image quality in the recommended recording mode, the recommended image quality of the recording mode may be a double speed of the recording that is 0.75 times the recording speed of the current recording mode. Further, for example, when the image quality is reduced in the recommended recording mode, a double speed of the recording that is 1.5 times the recording speed of the current recording mode may be set as the image quality of the recommended recording mode.

  Further, when the coverage ratio is less than the predetermined value, when the total time zone for recording in the current recording mode is 7 hours or more and the image quality in the current recording mode is 15 × speed recording, the control unit 105 A recording mode that reduces the total time zone to be recorded may be selected as a recommendation. Further, when the total time zone in which the current recording mode is recorded is 6 hours or less and the image quality of the current recording mode is 15 × speed recording, the control unit 105 does not need to set the recommended recording mode. Good.

  Further, in the recommended recording mode in which the image quality to be recorded is raised from the current setting, the control unit 105 sets the total time zone to be recorded separately from the recording mode in which the image quality is not changed from the current recording mode. Good. For example, the total time zone for recording in the recording mode set as recommended is (total time zone for current recording mode) / (double speed of recording for current recording mode) x (recording mode for higher image quality) (Double the recording speed). The double speed of recording in the recording mode when the image quality is increased may be set arbitrarily, and is not particularly limited. For example, when increasing the image quality in the recommended recording mode, the recommended image quality of the recording mode is set to a double speed of the recording 0.75 times the recording speed of the current recording mode.

  When the calculation result of the above equation is 16 hours or more, the total time zone for recording in the recording mode set as recommendation may be set to 16 hours. Further, when the above calculation result is 12 hours to 15 hours, the total time zone for recording in the recording mode set as recommendation may be set to 12 hours. In addition, when the calculation result described above is 8 hours to 11 hours, the total time zone for recording in the recording mode set as recommendation may be set to 8 hours. If the above calculation result is 7 hours or less, the total time zone for recording in the recording mode set as recommended may be set to 6 hours. By doing so, in the recommended recording mode in which the image quality to be recorded is raised more than the current setting, the control unit 105 can propose the recording mode suitable for the operator's reproduction pattern to the operator.

  Finally, the control unit 105 generates and outputs an image indicating the distribution of the reproduction pattern for each time zone subjected to the statistical analysis and an image reflecting the setting content of the recording mode determined to be recommended (S106). When the recommended recording mode is not set, the control unit 105 may generate and output an image indicating only the reproduction pattern for each time period of the operator. By doing so, the program recording / reproducing apparatus 100 can narrow down the programs to be recorded all. Therefore, the operator can check the reproduction pattern of each reproduced program in each broadcast time zone. Further, the operator can easily narrow down programs to be recorded in accordance with the operator's own reproduction pattern. When the operator selects recommendation, the control unit 105 issues an instruction to the recording unit 103 to change the recording mode. In this way, the operator can easily change the recording mode only by selecting the recording mode that suits the operator's own preference.

  Next, the offset value used when calculating the score value will be described.

  FIG. 3 is a diagram illustrating an example of an offset value used for statistical analysis for each broadcast time zone according to the first embodiment. The offset value is a value set in advance for each time zone. The offset value is set, for example, from the general number of times of viewing of the program for each time zone. The analysis time zone of the program may be set arbitrarily, for example, set every hour. As shown in FIG. 3, for example, the offset value is 0.0023 in the time zone from 19:00 to 19:59. The score value is calculated by adding the number of times of viewing and listening by the operator for each time period and the offset value. This makes it easier to select a general time zone where the number of times of viewing is high as a recommendation.

  Next, a method for determining a recommended image quality will be described.

  FIG. 4 is a diagram showing an example of changing double-speed recording when changing the image quality of a recorded program. The image quality is determined by the recorded speed. The image quality is lower as the numerical value of the double-speed recording is larger, and the image quality is higher as the numerical value of the double-speed recording is smaller. As shown in FIG. 4, a recommended image quality corresponding to the current image quality is determined in advance. For example, if the image quality of the current recording mode is 4 × speed recording, if the recording mode for lowering the image quality is selected as a recommendation, the 6 × speed recording is set, and if the recording mode for increasing the image quality is selected as a recommendation, Triple speed recording is set.

  First, the storage unit 101 stores the correspondence table shown in FIG. When the image quality to be recorded is changed from the current recording mode, the control unit 105 acquires the recommended image quality corresponding to the image quality of the current recording mode from the storage unit 101. Next, the control unit 105 instructs the recording unit 103 to change to the recording mode of the acquired image quality. If the current recording mode is already high image quality, that is, if recording cannot be performed in a state where the image quality is higher than the current recording mode, the control unit 105 does not need to select the recording mode for improving image quality as a recommendation. . For example, if the current image quality is set to a higher image quality than double-speed recording, even if the result of the statistical analysis indicates that the recording mode is to increase the image quality, the recording mode to increase the image quality is set not to be selected as a recommendation. Is also good.

  The method for determining the image quality may be set arbitrarily and is not particularly limited. The method of determining the recommended image quality may be such that the correspondence table is stored in the storage unit 101 in advance and is determined from the correspondence table, or may be calculated by a predetermined formula according to the double speed of recording in the current recording mode. . For example, when the recording mode for increasing the image quality is set as the recommendation, the recommended image quality of the recording mode may be a double speed of the recording that is 0.75 times the recording speed of the current recording mode. Further, for example, when the image quality is reduced in the recommended recording mode, a double speed of the recording that is 1.5 times the recording speed of the current recording mode may be set as the image quality of the recommended recording mode.

  Next, specific examples of recommended recording time, image quality, and total number of recording days will be described.

  FIG. 5 is a diagram illustrating an example of a current recording mode and a recommended recording mode according to the first embodiment. As shown in FIG. 5, the recording mode selected as a recommendation is determined by the current recording mode. FIG. 5A shows a case where the current recording mode is 24-hour recording per day, quadruple-speed recording, and the total number of recording days is 7 days, and the recording mode is changed to each. This is a recommended recording mode. The total number of recording days that can be stored in the storage unit 101 is calculated from the recording time per day, the image quality to be recorded, and the storage capacity of the storage unit 101. For example, if the recommended recording mode is selected as a recording mode that shortens the recording time zone and increases the image quality, the recommended recording mode is a recording time of 16 hours per day and an image quality of 3 hours. Double-speed recording and the total number of recording days are set to eight days. FIG. 5B shows the case where the current recording mode is 16 hours per day, the recording speed is 4 ×, and the total number of recording days is 10 days. This is a recommended recording mode. For example, if the recommended recording mode is selected to be a recording mode for lowering the image quality, the recommended recording mode is that the recording time per day is 16 hours, the image quality is 6 × speed recording, and the total number of recording days is 15 days. Is set to be

[1-2-2. Generation and output of statistical analysis result images and recommended images]
Next, a procedure from when the control unit 105 generates and outputs the above-described statistical analysis result and the recommended recording mode until the operator changes the recording mode will be described with reference to FIGS.

  FIG. 6 is a flowchart showing a procedure for changing the recording mode of the operator according to the first embodiment. FIG. 7 is a diagram illustrating an example of an image for confirming whether or not to display a result to an operator after statistical analysis. FIG. 8 is a diagram illustrating an example of a result of statistical analysis and a recommended image according to the first embodiment. FIG. 9 is a diagram illustrating an example of an image for confirming the timing of changing the recording mode. FIG. 10 is a diagram illustrating an example of an image displayed when the operator arbitrarily sets the recording mode.

  First, the storage unit 101 stores the number of programs reproduced by the analysis unit of the program reproduced by the reproduction unit 104. The control unit 105 acquires the number of reproduction programs stored in the storage unit 101 and analyzes the reproduction pattern for each time period. In order to make the analysis result more accurate, the statistical analysis of the number of reproduced programs for each analysis time zone is performed under a preset condition. When a preset condition is satisfied, the control unit 105 starts statistical analysis.

  Here, the condition set in advance is not particularly limited as long as the control unit 105 can acquire the number of reproduced programs necessary for statistical analysis. The preset condition may be set based on the number of programs to be reproduced. For example, a case where the number of reproduced programs is 20 or more may be set, or a case where the number of reproduced programs is 30 or more may be set.

  Further, the preset condition may be set based on the total playback time. For example, a case where the total reproduction time is 20 hours or more may be set, and a case where the total reproduction time is 30 hours or more may be set.

  Further, the preset condition may be set in a period during which the operator uses the program recording / reproducing apparatus 100. For example, it may be set as one month after the operator starts using the program recording / reproducing apparatus 100, or may be set as three months after the operator starts using the program recording / reproducing apparatus 100. .

  As shown in FIG. 6, first, the control unit 105 generates and outputs a notification image 300 (see FIG. 7) (S200). The time at which the notification image 300 is generated and output is not particularly limited, but may be, for example, immediately after the statistical analysis ends, or at the beginning of the next month after the statistical analysis ends. The timing at which the notification image 300 is output is not particularly limited. For example, the notification image 300 may be automatically displayed when the display device 200 is turned on, or the operator may use the program recording / reproduction device 100. It may be the timing that was done.

  When the operator selects to display the recommended image, the control unit 105 generates and outputs a time-zone-specific recommended image 400 (see FIG. 8) in which the time zone analysis result and the recommended recording mode are displayed (S201). ). When the operator selects the recommended recording mode, the control unit 105 generates and outputs a timing confirmation image 500 (see FIG. 9) for confirming when to change the recording mode (S202). The operator determines the timing for changing the recording mode, and ends the change of the recording mode. By doing so, the operator can easily change to a recording mode in which programs to be recorded are narrowed down according to the operator's own reproduction pattern. Further, the operator can easily change the recording mode simply by selecting the recording mode that suits his own preference.

  When the operator wants to change the recording mode in detail, the operator selects the favorite recording mode image 404 for changing the recording mode in detail. When the operator selects the favorite recording mode image 404, the control unit 105 generates and outputs the detailed setting image 600 (see FIG. 10) (S203). The operator makes detailed settings for the recording mode. After the operator finishes the recording setting, the control unit 105 generates and outputs the timing confirmation image 500 (S202).

  After the setting of the recording mode is completed, the control unit 105 may display a screen for viewing the program, or may display an image displayed before the notification image 300 is displayed. May be used, and there is no particular limitation. Further, the images generated by the control unit 105 such as the notification image 300 and the time-based recommended image 400 may be switched from the originally displayed image and displayed, or may be partially displayed on the originally displayed image. It may be displayed in an arbitrary manner, and there is no particular limitation.

  The above is the procedure in the first embodiment until the control unit 105 generates and outputs the statistical analysis result and the recommended recording mode, and the operator changes the recording mode.

  Next, the notification image 300 displayed in S200 of FIG. 6 will be described.

  The notification image 300 is an image for confirming to the operator that the statistical analysis has been completed and whether to confirm the statistical analysis result. As shown in FIG. 7, the notification image 300 includes a recommended display image 301, a recommended non-display image 302, and an end image 303.

  The recommended display image 301 is an image selected by the operator when confirming the statistical analysis result and the recommended recording mode.

  The recommended non-display image 302 is an image selected when the operator does not immediately check the statistical analysis result and the recommended recording mode.

  The end image 303 is an image selected by the operator when there is no need to display the statistical analysis result and the recommended recording mode in the future.

  Next, the time-based recommended image 400 displayed in S201 of FIG. 6 will be described.

  The time-zone-specific recommended image 400 is an image for displaying the operator's time-zone-specific reproduction pattern and the contents of the recording setting in the recommended recording mode. As shown in FIG. 8, the time-based recommended image 400 includes an analysis result image 401, a current recording mode image 402, recommended recording mode images 403a and 403b, and a favorite recording mode image 404.

  The analysis result image 401 is an image showing a reproduction pattern for each time zone of the operator. When the recording mode for changing the total time zone to be recorded is selected as a recommendation, the control unit 105 generates and outputs an image displayed so that the time zone to be recorded and the time zone to not be recorded can be distinguished. Is also good. Note that the analysis result image 401 is an image that displays a reproduction pattern for each time period of the operator, and the display method is not particularly limited.

(Embodiment 2)
Hereinafter, Embodiment 2 will be described with reference to FIGS.

[2-1. Constitution]
As shown in FIG. 1, the program recording / reproducing apparatus 100 according to the second embodiment is connected via a cable to an antenna 108 for receiving a program. The program recording / reproducing apparatus 100 is connected to the display apparatus 200 via a communication cable. The display device 200 includes a display unit 202 that displays information received from the program recording / reproducing device 100 as an image, and a communication interface 201 to which a communication cable is connected. The program recording / playback apparatus 100 includes a storage unit 101, a tuner 102, a recording unit 103, a playback unit 104, a control unit 105, a communication interface 106, and an operation unit 107.

  In the second embodiment, the control unit 105 further calculates a genre-based reproduction pattern that is a distribution of the reproduction time for each genre of the program reproduced by the reproduction unit 104. Based on the calculated genre-based reproduction pattern, the control unit 105 sets, as a recommended recording mode, a recording mode in which, among the reproduced genres, a genre having a short reproduction time is reduced in image quality to be recorded. By doing so, the control unit 105 sets a recording mode that increases the total number of recording days that can be stored in the storage unit 101.

  Further, the control unit 105 generates and outputs a recommended image for each genre indicating the determined recording mode. The control unit 105 controls the recording unit 103 to operate the recording unit 103 in the recording mode indicated by the recommended image when an instruction to select the outputted recommended image from the operator is acquired.

  Further, when there are a plurality of genres having a short reproduction time, the control unit 105 determines a genre for which the image quality is to be reduced according to a priority for each genre predetermined based on at least one of the broadcast frequency and the image quality of the programs included in the genre. decide. Here, the broadcast frequency of a program indicates the number of times and / or the broadcast time of the program broadcast during a predetermined period. The predetermined period is not particularly limited, but may be one day or one week.

  The priority is determined by the broadcast frequency and the image quality. The priority is set such that the higher the broadcast frequency of the program included in the genre, the higher the priority for determining the genre for lowering the image quality. In addition, for example, a genre in which image quality deterioration is not conspicuous, such as news, is set to have a higher priority as a genre for lowering the image quality.

[2-2. motion]
The operation of the program recording / reproducing apparatus 100 configured as described above will be described below. The program recording / reproducing apparatus 100 performs each operation of statistical analysis of a program reproduced by an operator, generation and output of a statistical analysis result image and a recommended image, and generation and output of a statistical analysis result image for each predetermined period. Do. Hereinafter, each operation will be described in detail.

[2-2-1. Statistical analysis of programs played by operators]
Next, a method of analyzing a reproduction pattern for each genre of the operator will be described with reference to FIGS.

  FIG. 12 is a flowchart showing a procedure of statistical analysis for each program genre in the second embodiment. FIG. 13 is a diagram illustrating an example of priorities used for statistical analysis for each genre according to the second embodiment.

  As shown in FIG. 12, the control unit 105 acquires the reproduction time for each genre of the program reproduced by the operator, stored in the storage unit 101, and analyzes the reproduction pattern of the operator (S400). Next, the control unit 105 analyzes the number of genres having a short reproduction time in the acquired program (S401).

  When there are a plurality of genres having a short reproduction time, the control unit 105 selects one or a plurality of genres from the genres according to the priority for each genre shown in FIG. 11 (S402). If there is only one genre with a short reproduction time, the control unit 105 selects that genre (S403). The method of selecting a genre having a short playback time is not particularly limited. May be selected from the following.

  Next, the control unit 105 analyzes the image quality of one or more selected genres (S404). The setting of the image quality to be changed is not particularly limited as long as the total number of recording days is increased. The setting of the image quality may be changed by, for example, the same method as the recording mode for lowering the image quality in the first embodiment.

  Finally, the control unit 105 generates and outputs an image indicating the analyzed distribution of the reproduction pattern of the operator and an image reflecting the setting content of the recording mode determined as recommended (S405). When the operator selects the recommended recording mode, the control unit 105 issues an instruction to the recording unit 103 to change the recording mode. By doing so, the operator can check the reproduction pattern for each genre of the reproduced program. Therefore, the operator can easily narrow down the programs to be recorded in accordance with the operator's own reproduction pattern. Further, the operator can easily change the recording mode simply by selecting the recording mode that suits his own preference.

  Next, the priority used for statistical analysis for each genre will be described.

  As shown in FIG. 13, the storage unit 101 stores in advance the priorities used for statistical analysis for each genre. In FIG. 13, for example, it is interpreted that the priority of news is 3 and the priority of sports is 4. FIG. 13 is interpreted that the priority of news is higher than the priority of sports. The priority is set based on the program broadcast frequency and the recorded image quality set for each genre. In other words, the priority is set such that the higher the broadcast frequency of the program included in the genre, the higher the priority for determining the genre for lowering the image quality. In addition, for example, a genre in which image quality deterioration is not conspicuous, such as news, is set so as to have a higher priority as a genre for lowering the image quality.

  Next, an example of a priority calculation method will be described.

  First, the control unit 105 acquires a broadcast frequency per day for each genre. The broadcast frequency is determined from the program broadcast time broadcasted per day. Next, the control unit 105 gives the numerical value A such that the higher the broadcast frequency is, the larger the value is for each genre. Further, the control unit 105 gives the numerical value B such that the genre in which the image quality deterioration is more conspicuous has a smaller value. That is, a numerical value A and a numerical value B are given for each genre. Next, the control unit 105 calculates a numerical value C by adding the numerical value A and the numerical value B for each genre. Finally, the control unit 105 assigns priorities to the genres in descending order of the numerical value C, and determines the priorities to be selected for the genres having lower image quality.

  By doing so, the control unit 105 can propose a recording mode suitable for the reproduction pattern of the operator to the operator.

[2-2-2. Generation and output of statistical analysis result images and recommended images]
Next, using FIG. 7, FIG. 9, FIG. 10, FIG. 14, and FIG. 15, the control unit 105 generates and outputs the above-described statistical analysis result and the recommended recording mode. The procedure for changing the recording mode will be described.

  FIG. 14 is a flowchart showing a procedure for changing the recording mode of the operator according to the second embodiment. FIG. 15 is a diagram illustrating an example of a result of statistical analysis and a recommended image according to the second embodiment.

  As shown in FIG. 14, first, the control unit 105 generates and outputs a notification image 300 (see FIG. 7) (S500). When the operator selects to display a recommended image, the control unit 105 generates and outputs a genre-based recommended image 700 (see FIG. 15) in which a genre-based analysis result and a recommended recording mode are displayed (S501). .

  When the operator selects the recommended recording mode, the control unit 105 generates and outputs a timing confirmation image 500 (see FIG. 9) for confirming when to change the recording mode (S502). The operator determines the timing for changing the recording mode, and ends the change of the recording mode. In this way, the operator can check the reproduction pattern of the reproduced program. Therefore, the operator can easily change to a recording mode in which programs to be recorded are narrowed down according to the operator's own reproduction pattern. Further, the operator can easily change the recording mode only by selecting the recording mode that suits his own preference.

  When the operator wants to change the recording mode in detail, the operator selects the favorite recording mode image 704. When the operator selects the favorite recording mode image 704, the control unit 105 generates and outputs the detailed setting image 600 (see FIG. 10) (S503). The operator makes detailed settings for the recording mode. After the operator finishes the detailed setting of the recording mode, the control unit 105 generates and outputs the timing confirmation image 500 (S502).

  The above is the procedure in the second embodiment until the control unit 105 displays the statistical analysis result and the recommended recording mode and the operator changes the recording mode.

  Next, the genre-based recommended image 700 displayed in S501 of FIG. 14 will be described.

  The genre-recommended image 700 is an image for displaying the reproduction pattern of the genre of the operator and the recording setting content of the recommended recording mode. As shown in FIG. 15, the genre-specific recommended image 700 includes an analysis result image 701, a current recording mode image 702, a recommended recording mode image 703, and a favorite recording mode image 704.

  The analysis result image 701 is an image showing a reproduction pattern for each genre of the operator. The analysis result image 701 may be any image that displays a reproduction pattern for each genre of the operator, and the display method is not particularly limited. For example, the ratio of the playback time for each genre to the total playback time may be displayed as a pie chart, or may be displayed as a bar graph with the playback time on the vertical axis and the genre on the horizontal axis.

  The current recording mode image 702 is an image that displays the current recording mode. When the operator does not change the recording mode from the current setting, the operator selects the current recording mode image 702.

  The recommended recording mode image 703 is an image that displays the recording mode selected by the statistical analysis, and one or more recommended recording mode images are displayed. As shown in FIG. 15, the recommended recording mode image 703 displays, for example, the image quality after the change of the recording mode of the selected genre. The selected genre may be displayed in the recommended recording mode image 703 or may be displayed in the analysis result image 701. When the operator wants to change the recording mode to the recommended recording mode, the operator selects the recommended recording mode image 703.

  The favorite recording mode image 704 is an image selected when the operator changes the recording mode in detail.

[2-2-3. Generation and Output of Statistical Analysis Result Image for Each Predetermined Period]
Next, a procedure in the case where the result of the repeated statistical analysis is displayed and the recommended recording mode is displayed at predetermined intervals will be described.

  FIG. 16 is a flowchart illustrating an example of a procedure for changing a recording mode performed by an operator when a recommended image is repeatedly displayed at predetermined intervals according to the second embodiment. First, the operator starts using the program recording / reproducing apparatus 100. One month after the operator starts using the program recording / playback apparatus 100, the control unit 105 generates and outputs the notification image 300 (S600). The operator performs the operation of changing the recording mode according to the flowchart shown in FIG. When the operator selects the recommended recording mode, the control unit 105 instructs the recording unit 103 to change the recording mode.

  Next, one month after the change of the recording mode, the control unit 105 generates and outputs the notification image 300 again (S601). The operator performs the operation of changing the recording mode according to the flowchart shown in FIG. Further, one month after S601, the control unit 105 generates and outputs the notification image 300 again (S602). The operator performs an operation of changing the recording mode according to the flowchart shown in FIG.

  If the operator does not select the recommended recording mode in S600, one month after the notification image 300 is output, the control unit 105 generates and outputs the notification image 300 again (S603). The operator performs an operation of changing the recording mode according to the flowchart shown in FIG.

  Although it has been described that the control unit 105 generates and outputs the notification image 300 every month, the period during which the notification image 300 is displayed is not particularly limited. The period during which the notification image 300 is displayed may be every two months or every three months. In addition, the control unit 105 may generate and output the display of the analysis result for each time zone and the display of the recommended recording mode, and the display of the analysis result for each genre and the display of the recommended recording mode at the same timing. .

[2-3. Effects etc.]
As described above, in the present embodiment, control unit 105 calculates, as a statistical analysis, a genre-based reproduction pattern that is a distribution of reproduction time for each genre of a program reproduced by reproduction unit 104 during a predetermined period.

  As a result, the operator can check the reproduction pattern for each genre of the reproduced program. Therefore, the operator can easily change to a recording mode in which programs to be recorded are narrowed down in accordance with the operator's own reproduction pattern.

  Further, in the present embodiment, the control unit 105 stores in the storage unit 101 by lowering the image quality at the time of recording for the genre having a short reproduction time among the reproduced genres based on the calculated genre-specific reproduction pattern. When a recording mode that increases the total number of recording days for a program that can be determined is determined, a recommended image indicating the determined recording mode is generated and output, and when an instruction to select the output recommended image from the operator is obtained, the The recording unit 103 is controlled so that the recording unit 103 operates in the recording mode indicated by the recommended image.

  Thereby, the operator can easily change the recording mode only by selecting the recording mode that suits the operator's own preference.

  Further, in the present embodiment, when there are a plurality of genres having a short reproduction time, the control unit 105 determines a priority for each genre predetermined based on at least one of a broadcast frequency and an image quality of a program included in the genre. According to the degree, the genre for lowering the image quality is determined.

  Thus, the control unit 105 can propose a recording mode suitable for the reproduction pattern of the operator to the operator.

  Further, in the present embodiment, the priority is set such that the higher the broadcast frequency of a program included in a genre, the higher the priority for determining the genre for lowering the image quality.

  Thereby, the operator can easily change to the recording mode in which the total number of recording days is increased.

  Further, in the present embodiment, the priority is set such that the lower the conspicuousness of the image quality deterioration of the program included in the genre is, the higher the priority of determining the genre for lowering the image quality is.

  This allows the control unit 105 to preferentially lower the image quality of a genre in which image deterioration when the preset image quality is lowered is not conspicuous.
