Description

  The present invention relates to an information recording / reproducing apparatus including a dubbing control means capable of dubbing from a built-in recording medium to a removable recording medium.

  Conventionally, an information recording apparatus capable of performing dubbing processing between different recording media has been proposed (see, for example, Patent Document 1).

When the start time or the end time is input and the time for dubbing is recognized, the information recording apparatus next checks the overlap between the recognized time and the recording reservation time reserved in advance. However, if any part of them is duplicated, a warning message to that effect is displayed on the reservation screen to alert the user and prompt the user to enter another reservation time. ing.
JP-A-2005-44423 ([0079] to [0081])

  Thus, according to the conventional information recording apparatus, dubbing can be performed at a time convenient for the user by setting the start time and end time of dubbing by the user. In that case, if the time set by the user overlaps with the scheduled recording time, a warning message to that effect is displayed, so the user changes the dubbing time to another time zone according to the warning. It becomes possible to do.

  Recently, DVD recorders with built-in hard disks (HD) have become widespread. A user who uses this HD built-in DVD recorder usually records the desired television program or the like on the HD, and dubbs what he wants to keep from the HD to the DVD. In this case, since the capacity of the mounted HD is increasing, recording can be performed from hundreds of hours to hundreds of hours in some cases unless image quality is given priority. When the recording is performed in the fine mode in which the image quality is prioritized, the HD capacity is filled with the recording for about several tens of hours. For this reason, when recording is performed in the fine mode, dubbing to a DVD is frequently required. In view of such a current situation, it is convenient for the user to perform the dubbing process as described above.

  However, in the conventional information recording apparatus, when changing the dubbing time, since it is not known which time zone does not overlap with the recording reservation time, the changed dubbing time zone is another recording reservation time. There is a possibility that it may overlap with the time zone. Therefore, in such a case, there is a problem that the user has to change the dubbing time many times. In addition, it is convenient if the user automatically sets an appropriate dubbing time that does not overlap with the recording reservation or the like by simply pressing the dubbing key, for example.

  The present invention was devised in view of such circumstances, and an object thereof is to provide an information recording / reproducing apparatus capable of easily changing a dubbing reservation time once set and automatically setting a dubbing reservation time. It is in.

In order to solve the above problems, the information recording / reproducing apparatus of the present invention performs dubbing immediately when the dubbing mode is set in the information recording / reproducing apparatus capable of dubbing from a built-in recording medium to a removable recording medium. The user can select one of dubbing mode, instant dubbing mode, time designation dubbing mode in which dubbing reservation time is specified by the user, and auto dubbing mode in which dubbing time is set on the device side It has been configured . That is, in the past, it was either the immediate execution dubbing mode or the time designation dubbing mode, but according to the information recording / reproducing apparatus of the present invention, the auto dubbing mode for setting the dubbing time on the apparatus side was further added. For example, the user can automatically set an appropriate dubbing time not overlapping with a recording reservation or the like on the apparatus side simply by pressing a dubbing key.

Also, the information recording / reproducing apparatus of the present invention is a selection means for the user to select information to be dubbed in the information recording / reproducing apparatus provided with a dubbing control means capable of dubbing from a built-in recording medium to a removable recording medium. And when the time designation dubbing mode in which the user designates the dubbing execution time and performs the dubbing reservation is selected, the dubbing control means includes the information selected by the selection means and the designated time. The dubbing reservation time zone is determined based on the above, and this dubbing reservation time zone is displayed in a horizontal bar shape on the reservation screen with the horizontal axis as the time axis. Is also configured to be displayed in a horizontal bar shape on the reservation screen.

According to the above configuration , the dubbing reservation time zone and the recording reservation time zone with time designation are displayed in a horizontal bar shape (that is, a bar graph shape) on the reservation screen with the horizontal axis as the time axis. When the recording reservation time zone overlaps, the situation including the degree of overlap can be confirmed at a glance. Therefore, it is easy to visually determine which time zone should be changed to the dubbing reservation time zone.

  In this case, the information recording / reproducing apparatus of the present invention further includes a movement instructing unit for moving the dubbing reservation time zone displayed in a horizontal bar shape in the time axis direction on the reservation screen, and the dubbing control unit When the dubbing reservation time zone is moved by the movement instructing means, the actual dubbing reservation time zone is changed along with the movement. That is, when the dubbing reservation time zone and the recording reservation time zone overlap, it is only necessary to move the dubbing reservation time zone to the time zone desired by the user on the reservation screen by the movement instruction means. The actual dubbing reservation time zone can be changed only by performing such an operation.

  Further, the information recording / reproducing apparatus of the present invention is configured such that when at least a part of the recording reservation time zone and the dubbing reservation time zone overlap on the reservation screen, the dubbing control means includes the dubbing reservation time zone, It may be configured to avoid duplication with the scheduled recording time period by dividing it before and after the scheduled recording time period. In this way, in the case of partial overlap, the dubbing operation can be performed efficiently at a timing closer to the time zone specified by the user by performing dubbing before and after the overlapping recording reservation time zone. Can be executed.

  Furthermore, the information recording / reproducing apparatus of the present invention further comprises a recording history storage means for storing each recording start time and recording time of the recording operation by the operation of the recording key and the recording operation by the recording reservation as a recording history, When the dubbing reservation time zone is determined, the dubbing control means compares the number of recording operations performed in the past from the recording history stored in the recording history storage means before and after the dubbing reservation time zone. A time period that is less than the target time is acquired, and the acquired time period is displayed on the reservation screen as a recommended dubbing reservation time period. In this case, the display color may be different between the recommended dubbing reservation time zone and other time zones. In this way, by displaying the recommended dubbing reservation time zone, the user can be presented with a time zone during which dubbing can be performed more safely and reliably (that is, a time zone in which recording reservations are less likely to occur afterwards). Therefore, the user can consider moving the current dubbing reservation time zone to this recommended time zone when he / she has time to dubb.

  Also, the information recording / reproducing apparatus of the present invention is a selection means for the user to select information to be dubbed in the information recording / reproducing apparatus provided with a dubbing control means capable of dubbing from a built-in recording medium to a removable recording medium. And recording reservation information storage means for storing recording reservation information including a recording reservation time zone, and when the auto-dubbing mode for setting the dubbing reservation time is selected on the apparatus side, the dubbing control means A dubbing reservation time zone is determined based on the information selected by the selection means and the recording reservation information stored in the recording reservation information storage means, and the horizontal axis represents the dubbing reservation time zone and the recording reservation time zone. It is displayed in a horizontal bar shape on a reservation screen with a time axis.

  According to the present invention, when the user simply presses the dubbing key, for example, the apparatus automatically sets an appropriate dubbing time that does not overlap with a recording reservation that has already been set. You can make a dubbing reservation with a simple operation. In this case, the automatically set dubbing reservation time zone and the recording reservation time zone are displayed in a horizontal bar shape (that is, a bar graph) on the reservation screen with the horizontal axis as the time axis. You can check the setting status of the reservation time zone at a glance.

  In this case, the dubbing control means may be configured to determine the dubbing reservation time zone in priority with the time when dubbing is completed earliest. For example, the dubbing control means, when the earliest dubbing available time zone is a time zone between any two recording reservation time zones, and when the dubbing reservation time zone does not fit in that time zone, One dubbing reservation time zone is set so as to be divided into a time zone that falls between them and a time zone that is behind the recording reservation time zone on the back side. In this way, by dividing one dubbing reservation, it is possible to effectively use a vacant time zone from the recording reservation to the next recording reservation, so the actual dubbing operation can be performed at an earlier timing. And can be executed efficiently.

  The dubbing control means may be configured to determine the dubbing reservation time zone with safety priority so that the dubbing reservation time zone can be surely avoided and dubbing can be performed. Specifically, it further comprises recording history storage means for storing the recording start time and recording time of the recording operation by the operation of the recording key and the recording operation by the recording reservation as a recording history, and when the auto dubbing mode is selected. The dubbing control means acquires a time zone in which the number of times of performing a recording operation in the past is relatively small from the recording history stored in the recording history storage means, and the auto-dubbing mode in the obtained time zone. The time zone closest to the selected time may be determined as the dubbing reservation time zone and displayed on the reservation screen. In this way, by determining a time zone in which the number of recording operations has been performed in the past as a dubbing reservation time zone, it is possible to avoid the occurrence of a situation in which recording reservations unexpectedly occur in overlapping time zones as much as possible. It becomes possible.

  In this case, the information recording / reproducing apparatus of the present invention further includes a movement instructing unit for moving the dubbing reservation time zone displayed in a horizontal bar shape in the time axis direction on the reservation screen, and the dubbing control unit When the dubbing reservation time zone is moved by the movement instructing means, the actual dubbing reservation time zone is changed along with the movement. Thus, even after the dubbing reservation time zone is automatically determined, if the recording reservation time zone overlaps, the dubbing reservation time zone is displayed on the reservation screen by the movement instruction means. It is only necessary to move to the desired time zone. The actual dubbing reservation time zone can be changed only by performing such an operation.

  Also, according to the information recording / reproducing apparatus of the present invention, the dubbing control means detects the remaining capacity of the removable recording medium, and the information amount of the information for which the dubbing reservation is made is larger than the remaining capacity of the recording medium. In some cases, a warning may be displayed on the reservation screen. By displaying warnings in this way, even if dubbing is possible in time, when dubbing is actually started, the capacity of the recording medium becomes full and dubbing is interrupted. Can be prevented.

  According to the information recording / reproducing apparatus of the present invention, the automatic dubbing mode in which the dubbing time is set on the apparatus side is added to the user side. For example, by simply pressing the dubbing key, an appropriate dubbing time not overlapping with the recording reservation or the like can be automatically set on the apparatus side. Also, by using such a function, there is no time for dubbing, the capacity of the built-in recording medium (for example, hard disk) becomes full, and any content that crys is deleted and a new program is recorded. The occurrence of such a situation can be prevented in advance.

  Further, according to the information recording / reproducing apparatus of the present invention, the dubbing reservation time zone and the recording reservation time zone which are designated for time are displayed in a horizontal bar shape, so that the dubbing reservation time zone and the recording reservation time zone overlap. In some cases, the situation can be confirmed at a glance including the degree of duplication. Therefore, it is possible to visually determine how to change the recording reservation time zone. In this case, since the dubbing reservation time zone displayed in a horizontal bar is provided with a movement instruction means for moving the dubbing reservation time zone in the time axis direction on the reservation screen, the dubbing reservation time zone and the recording reservation time zone overlap. In this case, the dubbing reservation time zone can be easily changed by merely moving the dubbing reservation time zone to the time zone desired by the user on the reservation screen by the movement instruction means.

  The information recording / reproducing apparatus according to the present invention further includes recording history storage means for storing the recording start time and the recording time of the recording operation by operating the recording key and the recording operation by recording reservation as a recording history. When the dubbing reservation time zone is determined, a time zone in which the number of recording operations performed in the past from the recording history stored in the recording history storage means is relatively small before and after the dubbing reservation time zone. Since it is configured to display the acquired time zone as a recommended dubbing reservation time zone with the display color changed on the reservation screen, the time during which dubbing can be performed more safely and securely for the user It is possible to present a band (that is, a time period in which recording reservations are rarely made after that). As a result, the user can consider moving the current dubbing reservation time zone to the recommended time zone when there is a time allowance for dubbing.

  Further, according to the information recording / reproducing apparatus of the present invention, the user can automatically set an appropriate dubbing time that does not overlap with a preset recording reservation, etc., simply by pressing the dubbing key. The user can make a dubbing reservation with a simple operation of pressing only one key. In this case, the automatically set dubbing reservation time zone and recording reservation time zone are displayed as horizontal bars on the reservation screen with the horizontal axis as the time axis, so the setting status of the dubbing reservation time zone and recording reservation time zone Can be confirmed at a glance.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing an electrical configuration of a hard disk (HD) built-in DVD recorder which is an embodiment of a video recording / reproducing apparatus according to the present invention.

  The DVD recorder 10 with built-in HD of this embodiment includes a control unit 1, a tuner 3 connected to an antenna 2 that receives broadcast radio waves such as a TV program, a signal processing unit 4, and a DVD (Digital Versatile Disk) 20 that is a recording medium. A detachable disc reading unit 5, a remote control receiving unit 6 that receives a control signal from the remote control 11, a display unit 7, an operation unit 8, and a hard disk (HD) 9, and the output of the signal processing unit 4 is a television receiver. (Hereinafter referred to as a television) 30.

  The control unit 1 includes a CPU 1a, a memory unit 1b, and a counter 1c that counts time for reproduction and recording. The memory unit 1b includes a ROM in which various operation programs of the present collider are stored, a RAM that temporarily stores various data and serves as a work area during operation, a flash memory that stores a recording history described later, an EEPROM, and the like. The tuner 3 extracts an analog signal including an image from the broadcast radio wave received by the antenna 2. The signal processing unit 4 includes an analog or digital signal processing circuit. The signal processing unit 4 outputs an analog signal input from the tuner 3 to the television 30 or digitizes it and then processes it into compressed data in the MPEG2 (Moving Picture Experts GroupPhase 2) format or the like to process the data on the disk reading unit 5 or Output to the control unit 1.

  The disk reading unit 5 is composed of a pickup, a pickup driving circuit, a disk driving circuit, and the like. The disc reading unit 5 records the data output from the signal processing unit 4 on the DVD 20, reads the data recorded on the DVD 20, and outputs the data to the signal processing unit 4. The signal processing unit 4 reproduces the data of the DVD 20 output from the disc reading unit 5, processes it into an analog signal, and outputs it to the television 30. The signal processing unit 4 includes an OSD circuit, and displays a menu screen, a reservation screen (to be described later), and the like on the monitor of the television 30 under the control of the control unit 1. The television 30 projects an image on a monitor such as a CRT based on the analog signal output from the signal processing unit 4, and outputs sound from a speaker.

  The display unit 7 displays time, the operating state of the recorder, and the like, and includes an FLD (fluorescent display tube), an LED lamp, and the like. The operation unit 8 is an operation panel unit provided with buttons, switches and the like provided on the front surface of the main body of the recorder.

  The remote controller 11 and the operation unit 8 are provided with keys that are operated to instruct the operation of the recorder 10 such as playback, recording, fast forward, rewind, and stop. In addition, a recording key or the like for setting a recording reservation (timer recording) is also provided. Further, the remote controller 11 is provided with a dubbing key for making a dubbing reservation which is a feature of the present invention.

  FIG. 2 is an explanatory diagram showing a key layout structure of the remote controller 11. However, FIG. 2 shows only the keys according to the present invention, and the other keys are omitted or simplified. That is, the remote controller 11 is provided with a power key 111, a numeric keypad 112, a dubbing key 113, a recording key 114, an up / down / left / right key 115, an enter key 116, and other various function keys 117.

For example, when the power key 111 of the remote control 11 is turned on, for example, the built-in hard disk 9 is selected as a recording medium, and the recording key 114 is operated, the control unit 1 is input from the outside through the antenna 2 and the tuner 3, Data such as a television program compressed by the processing unit 4 is recorded on the hard disk 9. At this time, if simultaneous playback (that is, viewing on the television 30) is selected, playback is performed simultaneously with recording, and the reproduced data is processed by the signal processing unit 4 and then output to the television 30. As a result, the TV program being recorded is displayed as a video on the monitor of the TV 30 and output as sound from the speaker.
Further, the control unit 1 operates the recording key 114 of the remote controller 11 or the recording start time of the preset recording reservation, such as a television program received by the tuner 3 and compressed by the signal processing unit 4. Data is recorded and stored in the hard disk 9.

  In addition, the control unit 1 has a dubbing function from the hard disk 9 to the DVD 20, and when setting the dubbing mode, the “immediate execution dubbing mode” in which dubbing is performed immediately, and the user designates the dubbing execution time. Either the “time designation dubbing mode” for making a dubbing reservation or the “auto dubbing mode” for setting the dubbing time on the recorder side can be selected. This selection is performed by key operation of the remote controller 11.

  Hereinafter, an example of the dubbing processing operation of the present embodiment will be described separately when the user selects “time designation dubbing mode” and when “auto dubbing mode” is selected.

  The first embodiment is an embodiment when the user selects the “time designation dubbing mode”. Hereinafter, a description will be given with reference to a monitor screen display example shown in FIG.

  That is, the user presses the dubbing key 113 of the remote controller 11 to display a dubbing selection screen (not shown) on the monitor of the television 30, and determines the dubbing destination (here, DVD20) and dubbing source (here, HD9) according to this dubbing selection screen. The title to be dubbed is selected from the list, and the recording mode (SP (Standard Play) mode, LP (Long Play) mode, SLP (Super Long Play) mode, etc.) during dubbing is selected. As a result, the title name selected by the user, the total time required for dubbing, the capacity, and the like are displayed on the dubbing selection screen. This completes the basic dubbing setting. Such selection operation and determination operation are operations conventionally performed by using the remote controller 11, and thus detailed description thereof is omitted here, but in general, the up / down / left / right key 115 and its central portion are omitted. This is done by operating the enter key 116 and the like arranged in FIG.

  When the basic setting is thus completed, a dubbing mode setting screen as shown in FIG. 3A is then displayed on the monitor of the television 30. In this dubbing mode setting screen, “immediate execution dubbing mode” that immediately executes dubbing, “time designation dubbing mode” in which the user designates the dubbing execution time to reserve dubbing, and dubbing time is set on this record side. The user selects the desired mode from among them and operates the enter key 116 on the remote controller 11 to set the selected dubbing mode. Transition.

  Here, the mode selection operation is performed by, for example, operating the up / down keys in the up / down / left / right keys 115 of the remote controller 11 to move the cursor (or cursor frame) displayed on the screen to a desired mode, and thereafter The enter key 116 of the remote controller 11 may be operated. Such a selection operation is the same in the following description. However, this selection operation is an example and is not limited to such an operation.

  Here, when the user selects the “time designation dubbing mode” and operates the enter key 116 of the remote controller 11, a time input screen shown in FIG. 3B is displayed. On the time input screen, after either the dubbing start time or end time is input, the enter key 116 of the remote controller 11 is operated.

  Thereby, the control unit 1 starts the information input from the hard disk 9 based on the previously input title (recording time, capacity, etc.) and the time input screen shown in FIG. A dubbing reservation time zone is determined based on the time or the end time. The dubbing reservation time zone 101 is displayed in a horizontal bar shape on the reservation screen with the horizontal axis as the time axis, as shown in FIG. At this time, if a recording reservation has already been set, the recording reservation time zones 201 and 202 are also displayed as horizontal bars on the reservation screen.

  By displaying in this way, when the dubbing reservation time zone 101 and the recording reservation time zones 201 and 202 overlap, the user can check the situation at a glance including the degree of overlap and the like. it can. As a result, the user can easily visually determine which time zone the dubbing reservation time zone 101 should be changed to. At this time, a message may also be displayed. For example, a message such as “The set dubbing reservation time zone overlaps with the recording reservation time zone. Please delete or change the dubbing reservation time zone.” Is displayed. As a result, the user can be warned of the necessity for deletion or change.

  Here, as shown in FIG. 3C, the dubbing reservation time zone 101 displayed in a horizontal bar shape on the reservation screen is operated by operating the left / right key in the up / down / left / right keys 115 of the remote controller 11. It can move left and right on the screen. Therefore, when there is an overlapping portion between the dubbing reservation time zone 101 and the recording reservation time zones 201 and 202, the user operates the left key or the right key so that the overlapping portion is eliminated, The dubbing reservation time zone 101 may be moved in a desired direction by a desired time width. FIG. 3D shows an example in which duplication with the recording reservation time zone 202 is eliminated by operating the right key of the up / down / left / right keys 15 to move the dubbing reservation time zone 101 in the right direction in the figure. Show. When the dubbing reservation time zone 101 is moved on the reservation screen in this way, the control unit 1 changes the actual dubbing reservation time zone along with this movement.

  In other words, when the dubbing reservation time zone and the recording reservation time zone overlap, the dubbing reservation time zone can be set on the reservation screen by the operation of the left key or the right key of the up / down / left / right key 115. Just move it to the belt. The actual dubbing reservation time zone can be changed only by performing such an operation.

  In the first embodiment, when the dubbing reservation time zone 101 is moved, it is described as a configuration in which the dubbing reservation time zone 101 is always moved as a unit (see FIGS. 3C and 3D). The dubbing may be ended earlier by effectively using the time zone between the bands 201 and 202. That is, as shown in FIG. 3E, the dubbing reservation time zone 101 is divided into a portion 101a that does not overlap with the recording reservation time zones 201 and 202 and a portion 101b that overlaps with the recording reservation time zone 202, and overlaps. About the part 101b, you may make it avoid duplication with the recording reservation time slot | zone 202 by moving after the recording reservation time slot | zone 202. FIG. Such division processing and display are automatically performed on the control unit 1 side. That is, when the right key of the up / down / left / right key 115 is operated to move the dubbing reservation time slot 101 to the right on the reservation screen, the overlapping portion is automatically divided along with this movement, and the overlapping recording reservation time It moves to the back side of the belt 202. Conversely, when the left / right key of the up / down / left / right key 115 is operated to move the dubbing reservation time slot 101 in the left direction on the reservation screen, although not shown in the figure, the overlapping portion is automatically displayed along with this movement. And are moved to the front side of the overlapping recording reservation time zone 201.

  In this way, in the case of partial overlap, the dubbing is performed before and after the overlapping recording reservation time zone, so that the recording reservation free time is close to the timing specified by the user. An efficient dubbing operation using the band effectively can be executed.

  The second embodiment is an embodiment in which recording history information is further added to the first embodiment.

  That is, in the second embodiment, the control unit 1 displays the recording day, the recording start time, the recording time, and the recording count of the recording operation by the operation of the recording key 114 of the remote controller 11 and the recording operation by the recording reservation. For example, in a flash memory of the memory unit 1b.

  FIG. 4 shows an example of recording history information stored in the flash memory.

  The recording history information includes items of recording day, recording start time, recording time, and number of recordings. Looking at this recording history information, recording has been performed for 60 minutes from 18:00 on Monday, and the number of times is one. In addition, recording is performed for 90 minutes from 20:00 on Tuesday, and the number of times is one. Furthermore, recording has been performed for 60 minutes from 22:00 on Tuesday, and the number of times is three. This indicates that, for example, a continuous drama has been broadcast from 22:00 on Tuesday, and this drama has been recorded for three episodes. That is, by looking at the number of times of recording, it can be seen that there is a high possibility of recording again in the same time zone on the same day of the week. However, in the second embodiment, the number of recordings is not particularly considered. Note that the recording history information may be updated on a monthly basis, for example. As a result, the latest recording history information is always stored in the flash memory.

  With reference to such recording history information, when the dubbing reservation is made, the control unit 1 executes the following process in addition to the process of the first embodiment.

  That is, when the dubbing reservation time zone 103 is determined by the user's time designation, the control unit 1 performs recording operations in the past from the recording history information stored in the flash memory before and after the dubbing reservation time zone 103. A time zone having a relatively small number of times of course (including 0 times as a matter of course) is acquired, and the acquired time zone is displayed on the reservation screen as a recommended dubbing reservation time zone. However, the number of recording operations that have been performed in the past may be set in advance for the recommended dubbing reservation time zone. For example, it is 0 when safety is taken into consideration most, but if it is about once, it is considered that there is no particular problem even if it is recommended as the recommended dubbing reservation time zone. However, in the example shown in FIG. 5, the number of recording operations performed in the past is 0 as a reference for determining the recommended dubbing reservation time zone.

  More specifically, if the dubbing reservation time zone 103 determined by the user's time designation is one hour from 17:30 on Monday as shown in FIG. Since it can be seen that recording is performed for 60 minutes from 18:00 on Monday, the control unit 1 displays a time zone area 301 after 19:00 that avoids the past recording time zone 203 as a recommended dubbing reservation time zone. . As an example of the display, the background color of the recommended dubbing reservation time zone 301 is displayed in blue, and the background colors of the other time zones 302 are displayed in yellow. By displaying the background color differently in this way, a time zone during which dubbing can be performed more safely and securely for the user (that is, a time zone in which recording reservations are less likely to occur afterwards) is provided. The user can move the current dubbing reservation time zone 103 to the recommended dubbing time zone 301 (indicated by reference numeral 103 ′ in FIG. 5) when there is a time allowance for dubbing. Can be considered.

  The third embodiment is an embodiment when the user selects the “auto dubbing mode”. Hereinafter, a description will be given with reference to screen display examples of the monitor shown in FIGS.

  That is, the user presses the dubbing key 113 of the remote controller 11 to display a dubbing selection screen (not shown) on the monitor of the television 30, and determines the dubbing destination (here, DVD20) and dubbing source (here, HD9) according to this dubbing selection screen. The title to be dubbed is selected from the list, and the recording mode (SP mode, LP mode, SLP mode, etc.) at the time of dubbing is further selected. As a result, the title name selected by the user, the total time required for dubbing, the capacity, and the like are displayed on the dubbing selection screen. This completes the basic dubbing setting.

  When the basic setting is thus completed, a dubbing mode setting screen as shown in FIG. 3A is then displayed on the monitor of the television 30. In this dubbing mode setting screen, “immediate execution dubbing mode” in which dubbing is immediately performed, “time designation dubbing mode” in which the user designates the dubbing execution time and dubbing reservation is set, and the dubbing time is set on the apparatus side. Since three mode selections of “auto dubbing mode” are displayed, the user selects “auto dubbing mode” from these and operates the enter key 116 of the remote controller 11.

  Thereby, when the recording reservation is already set, the control unit 1 determines the dubbing reservation time zone in consideration of the recording reservation information because the recording reservation information is stored in the memory unit 1b. . Specifically, the time zone in which dubbing can be performed earliest while avoiding the scheduled recording time zone is determined. Then, the determined dubbing reservation time zone 105 and recording reservation time zone 205 are displayed in a horizontal bar shape on a reservation screen with the horizontal axis as the time axis, as shown in FIG.

  In FIG. 6A, the time when the dubbing reservation is made is 17:00, the recording reservation is set for 2 hours from 18:00 one hour later, and the dubbing reservation time is 2 hours. Is illustrated. In this case, since there is only one hour between the dubbing reservation time (17:00) and the recording reservation time zone 205, and the two-hour part of the dubbing reservation time zone 105 does not enter, the dubbing reservation time zone 105 is set to the recording reservation time zone. It is set immediately after 205. On the other hand, FIG. 6B shows an example in which dubbing is set to end as soon as possible. The dubbing reservation time zone 105 is divided in half, and the dubbing reservation time zone 105a of the first half is changed to the dubbing reservation time (17). 0:00) to the scheduled recording time zone 205, and the dubbing reserved time zone 105b of the latter half is inserted immediately after the scheduled recording time zone 205 ends. That is, the divided dubbing is performed by dividing the recording reservation time zone 205 in the front and rear directions. As a result, the dubbing can be completed one hour earlier than in FIG.

  In the auto dubbing mode, the reservation screens shown in FIGS. 6A and 6B are final decision screens. If the user does nothing but only confirms the screen, the dubbing reservation is set as it is. In this case, for example, a “change” key may be displayed on the reservation screen, and the user may select this “change” key to make the change possible. The change operation at this time is the same as the operation described in the first embodiment, and the dubbing reservation time zone 105 is set to the time desired by the user on the reservation screen by operating the left key or the right key of the up / down / left / right key 115. Just move it to the belt. The actual dubbing reservation time zone can be changed only by performing such an operation.

  The fourth embodiment is an embodiment in which recording history information is further added to the third embodiment.

  That is, in the fourth embodiment, as in the second embodiment, the control unit 1 sets the recording day, the recording start time, and the recording time of the recording operation by the operation of the recording key 114 of the remote controller 11 and the recording operation by the recording reservation. The number of times of recording is stored as a recording history in, for example, a flash memory of the memory unit 1b (see FIG. 4).

  With reference to such recording history information, the control unit 1 executes the following process in addition to the process of the third embodiment when a dubbing reservation is made. Hereinafter, description will be given with reference to the flowchart shown in FIG.

  That is, after determining the dubbing reservation time zone 105 in consideration of the recording reservation information (step S1), the control unit 1 acquires the time zone in which the recording operation has been performed in the past from the recording history information stored in the flash memory. (Step S2), it is determined whether or not the acquired time zone overlaps with the recommended dubbing reservation time zone determined above (Step S3). As a result, if they do not overlap (if determined No in step S3), the dubbing reservation time zone 105 determined in step S1 is determined as the final dubbing reservation time zone and displayed on the reservation screen (step S5). On the other hand, if even a part of them overlaps, the dubbing reservation time zone 105 is changed so as to avoid duplication (step S4), and this is determined as the final dubbing reservation time zone (step S5). The change at this time may be changed after the overlapping past recording operation time zone as shown in FIG. 6 (a), or changed to divided dubbing as shown in FIG. 6 (b). Also good.

  Even if the dubbing reservation time zone is changed in this way, the recording reservation is not always set in the past past recording operation time zone that has been avoided. Therefore, the change may be wasted. Therefore, in consideration of such a case, when it is determined in step S3 that they overlap, the dubbing reservation time zone is not changed, and the time zone area after this past recording operation time zone is set as the recommended dubbing reservation time zone. It may be displayed together. As an example of the display, the background color of the recommended dubbing reservation time zone is displayed in blue as in the second embodiment, and the background color of the other time zones including the dubbing reservation time zone and the past recording operation time zone is yellow. indicate. At this time, a message may be displayed together. For example, a message such as “Recording reservation may be set in the set dubbing reservation time zone. Please consider changing to the recommended dubbing reservation time zone.” May be displayed.

  By displaying the background in different colors or displaying a message in this way, the user can be presented with a time zone during which dubbing can be performed more safely and securely. If there is enough time to do this, the current dubbing reservation time zone may be manually moved to this recommended dubbing time zone.

  In each of the first to fourth embodiments, the control unit 1 detects the remaining capacity of the DVD 20 that is the dubbing destination, and if the information amount of the information that has been reserved for dubbing is larger than the remaining capacity of the DVD 20, the reservation screen You may comprise so that a warning display may be performed above. As an example of the warning display, a message such as “The current recording mode cannot record all on the DVD 20, please change the recording mode” is displayed. By displaying the warning in this way, even when dubbing is possible in time, when dubbing is actually started, the capacity of the DVD 20 becomes full and dubbing is interrupted. Occurrence can be prevented.
