<First Embodiment>
The recording / reproducing apparatus of the present invention will be described below with reference to the drawings. It should be noted that this embodiment and the following embodiments show a recording / reproducing apparatus which is an example of a recording / reproducing apparatus in order to embody the technical idea of the present invention, and record / reproduce the recording / reproducing apparatus of the present invention. It is not intended to be specific to a device and is equally applicable to devices of other embodiments that fall within the scope of the claims. For example, the present invention may be applied to a recording / reproducing apparatus that records and reproduces sound.

  FIG. 1 is a diagram illustrating an example of the configuration of a recording / playback apparatus 100 according to the present embodiment. The tuner 2 acquires an output signal of the antenna 1 (hereinafter, “output signal of the antenna 1” may be referred to as “broadcast signal”). The tuner 2 multiplies the broadcast signal by a local oscillation signal having a frequency corresponding to the selected channel and converts the frequency into a baseband signal.

  The demodulator 3 demodulates the output signal of the tuner 2 and outputs a demodulated signal.

  The error correction unit 4 performs error correction as necessary on the output signal of the demodulator 3. The demultiplexing unit 5 demultiplexes and decodes the output signal of the error correction unit 4 into audio data (audio signal), video data (video signal), and EPG data, and each of them to the audio decoder 6, the video decoder 7, and a control unit 11 described later. Supply.

  The audio decoder 6 decodes the input audio data by, for example, the MPEG system and outputs it to a speaker or the like. The video decoder 7 decodes the input video data by, for example, the MPEG system and supplies it to the frame memory 8.

  The frame memory 8 is a memory area for temporarily storing video data. The video processing unit 9 converts the video data stored in the frame memory 8 into a video signal suitable for display on a display (not shown) and outputs the video signal to the display.

  The video processing unit 9 generates a video signal in which the OSD signal is superimposed on the video data stored in the frame memory 8 when the OSD signal output from the OSD generation unit 10 is input, and is suitable for display on a display. Convert to signal and output to display.

  The OSD generation unit 10 generates an OSD screen such as characters and graphics, and outputs an OSD signal obtained by converting the generated OSD screen to the video processing unit 9. In the present embodiment, in particular, the OSD screen displays a recording reservation setting screen (FIG. 3) generated by being controlled by the recording reservation setting unit 111 described later, and a list of unviewed recorded programs generated by being controlled by the presentation unit 113. A screen (FIGS. 4, 5, 10, 13, and 14) is generated.

  The control unit 11 is a control unit that controls the entire recording / playback apparatus 100. For example, the control unit 11 controls the OSD generation unit 10 to generate an OSD screen to be superimposed on the video data. In addition, the control unit 11 includes a recording reservation setting unit 111, a calculation unit 112, a presentation unit 113, and an erasure unit 114. In this embodiment, for simplification of description, a configuration in which one control unit 11 includes a recording reservation setting unit 111, a calculation unit 112, a presentation unit 113, and an erasing unit 114 is shown. It may be.

  The recording reservation setting unit 111 sets a recording reservation for a predetermined program. Programs for which recording reservations are set are programs individually designated by the user or a plurality of programs selected at a time based on predetermined conditions such as keyword designation and genre designation.

  The calculation unit 112 calculates the shortage capacity based on the free capacity of the storage medium 12 to be described later and the capacity necessary to record the program set by the recording reservation setting unit 111. The free capacity of the storage medium 12 is calculated by subtracting the used capacity from the total capacity of the storage medium 12. However, when a recorded program that has been viewed is erased by the erasure unit 114 described later, the available capacity of the storage medium 12 may be calculated by subtracting the used capacity and the occupied capacity of the recorded program that has been viewed from the total capacity.

  The capacity required for recording a program related to recording reservation (hereinafter, “capacity required to record a program related to recording reservation” is also referred to as “required capacity”) is used to record a program related to recording reservation. It is calculated based on the recording mode (image quality) and scheduled recording time. The insufficient capacity is calculated by subtracting the required capacity from the free capacity of the storage medium 12.

  The presentation unit 113 extracts and presents an unviewed recorded program that is recommended for viewing in order to compensate for the shortage capacity calculated by the calculation unit 112, that is, to increase the free capacity of the storage medium 12. The selection of an unviewed recorded program for which viewing is recommended may be selected at random, but it is desirable to sort the unviewed recorded programs based on a predetermined condition and select them in the sort order as will be described later. Details of the sorting method and the presentation method will be described later.

  The erasure unit 114 erases all or part of the recorded program that has been viewed when the capacity is insufficient (when the free space of the storage medium 12 is smaller than the necessary capacity). Details of the erasure will be described later.

  The storage medium 12 stores the recorded program. As the storage medium, an external or built-in storage medium is used, and in this embodiment, the recording / playback apparatus 100 is described as including an HDD which is a kind of storage medium.

  Hereinafter, processing executed by the control unit 11 of the recording / reproducing apparatus 100 of the present embodiment will be described with reference to FIG. FIG. 2 is a flowchart showing the flow of processing executed by the control unit 11 of the recording / playback apparatus 100. In step S01, the control unit 11 determines whether the recording reservation setting unit 111 is setting a recording reservation for a specific program. For example, when the recording reservation is set by the user, the program title and the recording mode are specified on the recording reservation setting screen displayed on the display as shown in FIG. This is the stage before being pressed.

  If the recording reservation is being set (Y in step S01), the process proceeds to step S02. If the recording reservation is not being set (N in step S01), the process returns to step S01.

  In step S02, the calculation unit 112 of the control unit 11 is designated with the free space of the storage medium 12 (the recording destination HDD shown in FIG. 3) and the program that is scheduled for recording (11 channels on the ground D in FIG. 3) in step S01. The capacity required for recording in the recording mode (AE mode in FIG. 3) is calculated. Then, the shortage capacity is calculated based on the calculated free capacity and necessary capacity. When the calculation unit 112 determines that the capacity shortage occurs based on the calculation result (Y in step S02), the control unit 11 proceeds to step S03, and when it determines that the capacity shortage does not occur (N in step S02), the step Proceeding to S06, the recording reservation setting is terminated. As shown in FIG. 3, when the recording reservation setting is made by the user's operation, the recording reservation setting is ended when the user presses the confirmation.

  In step S03, the presentation unit 113 of the control unit 11 sorts the unviewed recorded programs based on the occupied capacity per unit time. The occupied capacity of each program greatly depends on the recording mode, and there are long and short broadcast times even with the same occupied capacity. If the occupied capacity per unit time is large, the required capacity can be efficiently secured by erasing the short-time viewing.

  In step S04, the presentation unit 113 of the control unit 11 sorts the unviewed recorded programs sorted in step S03 in order of sorting, that is, in order from the largest occupied capacity per unit time. Extract and present recorded programs. An unviewed recorded program is presented, for example, as shown in FIG. Further, for example, when the recording reservation setting unit 111 automatically sets a recording reservation for a program related to the specified genre, as shown in FIG. 5, the program is viewed for recording a program scheduled to be broadcast on each day. Show unrecorded recorded programs that should be (viewed and deleted).

  In step S05, the control unit 11 determines whether an unviewed recorded program has been deleted. Note that “unviewed” in this step is determined based on whether or not unviewed at the current time regardless of whether or not unviewed at the present time. This is because the program presented in step S04 may be erased after being viewed by the user, or may be erased without viewing. When an unviewed recorded program is erased (Y in step S05), the process returns to step S02, and when an unviewed recorded program is not erased (N in step S05), the process returns to step S05. If the unviewed recorded program presented in step S04 is deleted, the process may proceed to step S06.

  If an unviewed recorded program is not deleted, the recording reservation setting may be interrupted without returning to step S05.

  According to the present embodiment, an unviewed recorded program to be viewed to ensure the necessary capacity is presented. At that time, since an unviewed recorded program with a large occupied capacity per unit time is presented, it can be viewed in a short time, and the necessary capacity can be efficiently secured by deleting the recorded program after viewing.

Second Embodiment
In the first embodiment, the unviewed recorded programs are sorted based on the occupied capacity per unit time, but the sorting method is not limited to this. A recorded program having a large occupied capacity per unit time can be viewed in a short time, but if the required capacity is large, it may be necessary to view many programs. A user who wants to save many programs may want to secure the necessary capacity by viewing and erasing fewer recorded programs. Therefore, in this embodiment, unviewed recorded programs are sorted based on the total occupied capacity.

  Hereinafter, processing executed by the control unit 11 of the recording / reproducing apparatus 100 of the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing the flow of processing executed by the control unit 11 of the recording / playback apparatus 100 of this embodiment. Note that steps S11 to S12 and S15 to S16 in the flowchart in FIG. 6 are the same as steps S01 to S02 and S05 to S06 in the flowchart in FIG.

  In step S13, the presentation unit 113 of the control unit 11 sorts the unviewed recorded programs based on the total occupied capacity. By viewing and erasing a program having a large total occupied capacity, it is possible to erase a small number of recorded programs and secure the necessary capacity.

  In step S14, the presentation unit 113 of the control unit 11 selects one or a plurality of unviewed recorded programs corresponding to the insufficient capacity in the sort order from the unviewed recorded programs sorted in step S13, that is, in descending order of the total occupied capacity. Extract and present. Presentation of an unviewed recorded program is performed in the same manner as in the first embodiment.

  According to the present embodiment, an unviewed recorded program to be viewed to ensure a necessary capacity is presented. At that time, since an unviewed recorded program having a large total occupied capacity is presented, the necessary capacity can be ensured by deleting a smaller number of recorded programs.

<Third Embodiment>
In the first and second embodiments, unviewed recorded programs are sorted based on the occupied capacity per unit time or the total occupied capacity, and presented in the sort order. However, there are cases where unviewed recorded programs may not be viewed at this time, should not be viewed, may not be viewed, or may not be deleted even if viewed. In this embodiment and the following embodiments, an unviewed recorded program to be presented based on requirements other than the occupied capacity per unit time or the total occupied capacity is extracted and presented.

  In the following embodiments, unrecorded recorded programs are described as being sorted based on the occupied capacity per unit time. However, as a modified example, the recorded programs may be sorted based on the total occupied capacity.

  Hereinafter, processing executed by the control unit 11 of the recording / reproducing apparatus 100 of the present embodiment will be described with reference to FIG. FIG. 7 is a flowchart showing the flow of processing executed by the control unit 11 of the recording / reproducing apparatus 100 of this embodiment. Note that steps S21 to S23 and S27 to S28 in the flowchart of FIG. 7 are the same as steps S01 to S03 and S05 to S06 in the flowchart of FIG.

  In step S24, the control unit 11 determines whether there is a program whose order to be viewed is determined among the unviewed recorded programs sorted in step S23. A program whose order to be viewed is determined is a program in which a story develops as the number of stories increases, such as a drama. For example, when the first episode and the second episode of the drama are recorded and unviewed, the first episode should be viewed first even if the second episode has a larger occupied capacity per unit time than the first episode. is there. Therefore, when there is a program in which the order to be viewed is determined (Y in step S24), the control unit 11 proceeds to step S25 to switch to the order to be viewed, and one or a plurality of unviewed corresponding to the insufficient capacity in the sort order. The recorded program is extracted and presented.

  Specifically, when unrecorded recorded programs are sorted as shown in FIG. 8 in step S23, the second episode of drama F should be viewed after the first episode of drama F. FIG. As shown in FIG. 10, the second episode of drama F is presented after the first episode of drama F as shown in FIG.

  In other words, when there is an unviewed recorded program with the same title as an unviewed recorded program related to the presentation, the recording date and time of the unviewed recorded program related to the presentation may be presented after that. It is determined whether or not the recorded program is the oldest. If the recording date and time is the oldest, the position is kept as it is, and if there is another program with an old recording date and time, the program is moved to that recording program. Then, the recorded program is presented according to the sort order.

  In the present embodiment, the title is a “main title” that does not include “subtitle” or “number of stories”, and the same title indicates that the main title is the same. When the title information includes a mixture of the main title, subtitle, number of stories, and the like, it may be determined that the main title is the same for those having a degree of coincidence exceeding a certain degree of coincidence. For example, the above-mentioned “Drama F Episode 1” and “Drama F Episode 2” differ only in numerical values, and the other six characters (excluding spaces) are in common and have high coincidence, so that they are determined to be the same title. The degree of coincidence may be set as appropriate, but it is desirable to determine the same title even with a relatively low degree of coincidence in consideration of cases other than the main title such as a subtitle.

  On the other hand, when there is no program in which the order to be viewed is determined (N in step S24), the process proceeds to step S26, and one or more unrecorded programs corresponding to the shortage capacity are sorted in the order of sorting from the unviewed recorded programs sorted in step S23. Extract and present a recorded program for viewing.

  According to the present embodiment, the same effects as those of the first embodiment can be obtained. In addition, since the order is changed with respect to the program in which the order to be viewed is changed, an unviewed recorded program is presented, which is highly convenient.

<Fourth embodiment>
Processing executed by the control unit 11 of the recording / playback apparatus 100 of this embodiment will be described with reference to FIG. FIG. 11 is a flowchart showing the flow of processing executed by the control unit 11 of the recording / playback apparatus 100 of this embodiment. Note that steps S31 to S33 and S37 to S38 in the flowchart of FIG. 11 are the same as steps S01 to S04 and S05 to S06 in the flowchart of FIG.

  In step S34, the control unit 11 determines whether or not there is a viewing time designation (designated time) from the user. That is, the user may be able to view the program only for a limited time due to business or the like. For example, when the user wants to finish viewing within 3 hours, the user cannot complete viewing when the playback time of an unviewed recorded program having the largest occupied capacity per unit time is 4 hours. Therefore, when the viewing time is designated (Y in step S34), the control unit 11 proceeds to step S35 and extracts one or a plurality of unviewed recorded programs corresponding to the shortage so that the reproduction time is equal to or less than the designated time. And present it.

  In this embodiment, the playback time of an unviewed recorded program is the time when the program is viewed from the beginning to the end at the standard speed. However, when it has a function to skip the commercial broadcast, the time excluding the commercial broadcast time It is good. Further, it may be the time when an unviewed recorded program is reproduced in the speech speed conversion mode (1.4 times speed). By specifying whether or not to skip commercial broadcasts along with the playback time and the playback speed, it is possible to skip the commercial broadcast and / or calculate the playback time when the playback speed is changed.

  On the other hand, if no viewing time is specified (N in step S34), the process proceeds to step S36, and one or a plurality of unviewed recorded programs corresponding to the shortage capacity are extracted from the unviewed recorded programs sorted in step S33 in the sort order. And present it.

  According to the present embodiment, the same effects as those of the first embodiment can be obtained. In addition, since one or a plurality of unviewed recorded programs are extracted and presented within a range that can be viewed within the designated time, the convenience is high.

<Fifth Embodiment>
Processing executed by the control unit 11 of the recording / playback apparatus 100 of the present embodiment will be described with reference to FIG. FIG. 12 is a flowchart showing the flow of processing executed by the control unit 11 of the recording / playback apparatus 100 of this embodiment. Note that steps 41 to S44 and S47 to S48 in the flowchart of FIG. 12 are the same as steps S01 to S04 and S05 to S06 in the flowchart of FIG.

  In step S45, the control unit 11 determines whether or not there is an instruction to exclude one or more unviewed recorded programs among the unviewed recorded programs presented in step S44. The unviewed recorded program may include a program that the user does not want to view now, such as a program recorded by another person (such as a family member) or a program that the user wants to watch together. Therefore, for example, as shown in FIG. 13, when an unviewed recorded program is presented, a check box is provided in front of each title, and an exclusion instruction can be made by pressing exclude in a state where the check box is checked.

  If there is an exclusion instruction for one or a plurality of unviewed recorded programs (Y in step S45), the process proceeds to step S46 to exclude one or a plurality of unviewed recorded programs corresponding to the shortage capacity by excluding the program related to the exclusion instruction. Is extracted and presented. As shown in FIG. 13, when the exclusion is instructed with the check box of the program J being checked, the program J is excluded as shown in FIG.

  On the other hand, if there is no exclusion instruction for one or a plurality of unviewed recorded programs (N in step S45), the process proceeds to step S47.

  According to the present embodiment, the same effects as those of the first embodiment can be obtained. In addition, it is possible to instruct to exclude the presented unviewed recorded program, and since another unviewed recorded program is presented instead of the program related to the exclusion instruction, the convenience is high.

<Sixth Embodiment>
In the first to fifth embodiments, an unviewed recorded program is presented, but even if the viewing is performed, the necessary capacity cannot be ensured unless it is deleted. It is a burden on the user to find and delete a program viewed from many programs displayed in the recorded program list after the viewing ends. In view of this, in this embodiment, deletion support for recorded programs that have been viewed is provided.

  Although this embodiment will be described as a modification of the first embodiment, it can also be applied to the second to fifth embodiments.

  Processing executed by the control unit 11 of the recording / playback apparatus 100 of this embodiment will be described with reference to FIG. FIG. 15 is a flowchart showing the flow of processing executed by the control unit 11 of the recording / reproducing apparatus 100 of this embodiment. Note that steps S51 to S54 and S57 in the flowchart in FIG. 15 are the same as steps S01 to S04 and S06 in the flowchart in FIG.

  In step S55, the control unit 11 determines whether or not viewing of an unviewed recorded program has ended. If viewing has ended (Y in step S55), the process proceeds to step S56, and the erasure unit 114 of the control unit 11 erases the recorded program that has been viewed, and the process returns to step S52. If viewing has not ended (N in step S55), the process returns to step S55.

  In this embodiment, the recorded program viewed in step S56 is erased, and then the process returns to step S52. However, if the program that has been viewed is an unviewed recorded program presented in step S54, the process returns to step S57. It is also possible to proceed.

  Further, before the automatic erasure in step S56, the user may be asked for permission to delete, and when the permission is obtained, it may be deleted.

  According to the present embodiment, the same effects as those of the first embodiment can be obtained. In addition, after viewing of an unviewed recorded program is completed, support for erasing the program is provided, which is highly convenient.

<Seventh embodiment>
In the above first to fifth embodiments, viewing of an unviewed recorded program is presented in order to secure the necessary capacity, but viewing of the remaining time until the start time of the program related to recording reservation is not presented. It may be shorter than the playback time of the recorded program. In such a case, if an unviewed recorded program has been viewed and then deleted, it will not be in time for the start of recording. Therefore, in the present embodiment, the necessary capacity is secured by deleting or overwriting the already viewed part during the reproduction of the unviewed recorded program.

  Although this embodiment will be described as a modification of the first embodiment, it can also be applied to the second to fifth embodiments.

  Processing executed by the control unit 11 of the recording / playback apparatus 100 according to the present embodiment will be described with reference to FIG. FIG. 16 is a flowchart showing the flow of processing executed by the control unit 11 of the recording / playback apparatus 100 of this embodiment. Note that steps 61 to S64 and S69 in the flowchart of FIG. 16 are the same as steps S01 to S04 and S06 of the flowchart of FIG.

  In step S <b> 65, the control unit 11 determines whether or not a reproduction instruction has been given to a recorded program that has not been viewed by the user. If a reproduction instruction has been given (Y in step S65), the process proceeds to step S66, and if no reproduction instruction has been given (N in step S65), the process returns to step S65.

  In step S66, based on the playback end time of the unviewed recorded program that has been instructed to be played in step S65 and the broadcast start time of the program related to the recording reservation, the control unit 11 before the broadcast start time of the program related to the recording reservation is reached. It is determined whether viewing of an unviewed recorded program ends. When viewing of an unviewed recorded program ends before the broadcast start time of the program related to recording reservation (Y in step S66), the process proceeds to step S67, and the erasure unit 114 erases the recorded program after the reproduction of unviewed recording is completed. To do. At this time, as described above, the user may be asked for permission to delete, and when the permission is obtained, it may be deleted.

  When viewing of an unviewed recorded program does not end before the broadcast start time of the program related to the recording reservation (N in step S66), the process proceeds to step S68, and the erasure unit 114 is the portion that has been viewed during the reproduction of the unviewed recorded program. Is deleted.

  After the processes of steps S67 and S68, the process returns to step S62. In this embodiment, when the process returns from step S68 to step S62, the calculation unit 112 calculates a free capacity when an unviewed recorded program that is currently being reproduced is deleted, and uses the free capacity and the required capacity. Based on this, the shortage capacity is calculated.

  According to the present embodiment, the same effects as those of the first embodiment can be obtained. In addition, even when playback of an unviewed recorded program does not end before the program end time related to the recording reservation, it is possible to record the program related to the recording reservation while playing the unviewed recorded program. Is expensive.
