Description

  The present invention relates to a recording apparatus that organizes recording media when a recording capacity is insufficient.

  Conventionally, a tuner that receives a broadcast program and a DVD recorder that records a broadcast program with a built-in recording medium such as a DVD or a hard disk has been put into practical use. In such an apparatus, if the capacity of the recording medium is insufficient, no further recording is possible, and the user has to organize the storage medium.

Patent Document 1 discloses a recording / reproducing apparatus that searches for broadcast program candidates to be deleted when there is not enough free space on a recording medium.
JP 2004-328608 A

  However, the configuration of Patent Document 1 is not sufficient as to which recorded data should be deleted. For example, when it is not possible to record a target broadcast program without deleting a plurality, it is not easy to select the combination.

  Accordingly, it is an object of the present invention to provide a recording apparatus in which excessive recording data is not deleted by accurately indicating the recording data to be deleted.

  In the present invention, means for solving the above-described problems are configured as follows.

(1) a recording medium for recording recording data;
Recording means for recording the input video signal as recording data on the recording medium;
In a recording apparatus comprising: an organizing unit that organizes the recording medium when the recording medium has insufficient capacity when the recording unit newly records a predetermined video;
The organizing means is:
Search means for searching for a first candidate of recorded data to be deleted among recorded data recorded on the recording medium;
Displaying a list of recorded data recorded on the recording medium, and, if there is a first candidate searched by the search means, a display means for outputting the list of the first candidates;
Selection accepting means for accepting selection of a second candidate of recorded data to be deleted from a list of recorded data recorded on the recording medium and accepting selection of recorded data to be deleted from the first candidate; Prepared,
The search means is included in the second candidate in addition to the total capacity V of the second candidate (provided that the total capacity V = 0 when the second candidate is not selected). When a new recorded data X is deleted, a candidate for the recorded data X that solves the shortage of capacity is searched as the first candidate, and each time the second candidate is selected by the selection receiving means To search for the first candidate,
The display means reflects the change of the first candidate every time the search means searches for the first candidate.

With this configuration, the following effects occur.
(A) If the lack of capacity can be resolved by deleting one recorded data, a display of the candidate is output. Therefore, deleting this recorded data frees the user from organizing work. There is no need to delete multiple recorded data by mistake.
(B) Even if one recorded data is deleted, even if the capacity shortage cannot be resolved, if the recorded data is selected, the recorded data to be deleted is indicated. Therefore, the user can make a prospect of which recorded data should be deleted as a set.
(C) Further, when the user selects and corrects the recording data, the searching means searches the recording data X that solves the shortage of capacity accordingly, and if there is the recording data X, displays this display. Output. If the recording data selected by the user is selected and corrected, a more appropriate set of recording data to be deleted can be searched.
(D) As described above, since the optimum recorded data can be deleted, it is not necessary to delete the recorded data excessively.

  (2) When the display means displays the list of the first candidates, the sum of the total capacity V and the capacity of the recording data X searched by the search means is calculated by the recording means as the predetermined video. Are displayed in the order closest to the capacity that is insufficient to record new images.

  According to this configuration, the user can know a list of the minimum necessary recording data to be erased when the new recording is performed. Therefore, for example, if it is sufficient to erase 500 megabytes, it is not necessary to delete the recording data having a capacity of 1 gigabyte by mistake. Therefore, it is possible to prevent unnecessary recording data from being deleted.

(3) The selection accepting unit accepts selection of the recording data Z from a list of recording data recorded on the recording medium and accepts editing of the recording data Z.
The search means searches for the first candidate every time the recorded data Z is edited and partially deleted.

  In this configuration, it is possible to delete the recorded data partially by editing the recorded data, the search means searches based on the deleted result, and the display means displays this, so it is unnecessary more precisely. It is possible to delete only unnecessary data and not to delete excess recorded data.

  (4) The display means outputs a check mark display together with the display of the second candidate and the third candidate, and when any of these candidates is selected by the selection receiving means, The check mark is changed.

  In this way, the user can easily determine that the recording data is selected. Examples of the method for changing the check mark include a change in shape, color, and pattern.

  (5) The recording medium may be a hard disk, an optical disk, or a flash memory.

  According to the recording apparatus of the present invention, it is possible to accurately indicate the recording data to be deleted, and it is possible to prevent unnecessary recording data from being deleted.

  FIG. 1 is a block diagram showing the configuration of the main part of a DVD recorder 1 according to an embodiment of the present invention. The DVD recorder 1 of this embodiment records a video signal on a recording medium such as a DVD and reproduces recorded data recorded on the recording medium.

  The DVD 10 that can be mounted on the DVD recorder 1 of this embodiment is a rewritable DVD-RW or the like, or a recordable optical disc DVD-R, but is not limited to the DVD of this embodiment, and other optical discs. Even when recording, this apparatus can be applied.

  A video signal and an audio signal are input to the input unit 2. The video signal and the audio signal are, for example, received by an antenna (not shown), or a cable analog format or digital format video signal. The video signal and audio signal may be input from a VHS tape drive.

  The encoding unit 3 converts the analog format video signal and audio signal input by the input unit 2 into digital signals and encodes them. The encoding unit 3 outputs the encoded data to the disk drive 4.

  The recording / reading unit 4 includes an optical disk drive 41, which is a kind of recording medium, a hard disk 42 (abbreviated as HD42), and a hard disk drive 43 (abbreviated as HDD 43). The optical disk drive 4 performs a pickup head (not shown) that irradiates the DVD 10 with laser light and detects the reflected light, and focus servo control and tracking servo control that control the irradiation position of the laser light irradiated on the DVD 10. It has a servo control unit (not shown) to perform. With these configurations, the optical disk drive 41 reads and records the DVD 10. The HD 42 is one type of recording medium. The HDD 43 reads and writes the HD 42. Note that the recording medium of the present embodiment only needs to be able to record video signals and audio signals, and includes not only portable media but also those used for installation.

  With such a configuration, the recording / reading unit 4 records the video signal and the audio signal encoded by the encoding unit 3 on the DVD 10 or the HD 42. Hereinafter, recording of a video signal and an audio signal on a recording medium is referred to as recording. In addition, you may provide the structure which reads and records the flash memory which is 1 type of a recording medium.

  The signal processing unit 5 includes a demodulation unit, a decoder, and an OSD synthesis unit. The demodulator demodulates video data and audio data from the RF signal read by the disk drive 4 and performs error correction. The decoder decodes video data and audio data. The OSD synthesis unit 5 synthesizes an OSD (On-Screen Display) such as characters and characters of the OSD synthesis unit 5 based on a command issued by the control unit 9. When a video signal is output from the decoder, this video signal and OSD (On-Screen Display) are combined and output to the output unit 6.

  The output unit 6 includes a D / A converter and the like, and D / A converts the video signal and audio signal processed by the signal processing unit 5. The output unit 6 synchronizes the D / A converted video signal and audio signal and outputs them to the display 11 and the speaker 12.

  The operation unit 8 receives an operation input for the apparatus main body. The operation unit 8 has a remote control reception unit that receives a plurality of operation keys and a control code for the apparatus main body transmitted from a remote control apparatus (not shown). The operation unit 8 receives an input corresponding to an operation key operated by the user, and transmits a code corresponding to the key and a control code received by the remote control reception unit to the control unit 9. For example, the operation unit 8 receives an instruction for recording (that is, recording of a video signal on the DVD 10) and an input for recording reservation.

  The control unit 9 includes a system IC including a microcomputer or a microcomputer module, and includes a CPU, a RAM, and a ROM for storing control data. Based on the input received by the operation unit 8, the control unit 9 controls the operations of the respective units 2 to 8 among the devices described above. The ROM of the control unit 9 stores a subroutine for executing a recording reservation process 91 for performing a recording reservation in advance, an organizing process 93, and a recording process 94 for controlling the start and stop of the recording operation.

  The recording reservation process 91 includes a recording reservation reception process and a post-process. In the recording reservation accepting process, the control unit 9 accepts selection of a recording reservation item.

  The recording reservation receiving process is executed by receiving a predetermined key operation before starting a broadcast program to be recorded. In the recording reservation receiving process, the scheduled recording time T [H], the scheduled recording time, the channel number of the television to be recorded, the recording mode for designating the image quality, and the designation of the recording medium to be recorded are accepted from the user.

  The recording medium may be an HDD, a DVD, or other flash memory. Hereinafter, the same applies to the recording medium.

  In the recording reservation receiving process, the control unit 9 calculates an approximate recording capacity necessary for the recording reservation from the multiplication of the bit rate of the designated recording mode and the recording time. Further, in the recording reservation process 91, the control unit 9 compares the remaining capacity of the designated recording medium with the recording capacity necessary for the recording reservation in the recording reservation receiving process. If the remaining capacity is insufficient, the organizing process 93 is performed.

  The organizing process 93 includes a search process, an OSD (On-Screen Display) process, and a selection reception process. In the search process, candidates for recording data to be deleted are searched. In the OSD process, the searched recording data and the like are displayed. In the selection reception process, selection of recording data to be deleted is received. In the OSD process, changes in the OSD are reflected as the search process and the selection reception process are executed.

  When the capacity shortage is resolved by the organizing process 93, the control unit 9 returns to the recording reservation process 91 and executes post-processing of the recording reservation process 91.

  In the post-processing, the control unit 9 records the recording reservation data on a recording medium or a flash memory (not shown) in the control unit 9 (which may be connected to the control unit 9). The control unit 9 interrupts based on the data recorded in the post-processing and calls and executes a subroutine of the recording process 94. In the recording process 94, the control unit 9 controls the start and stop of the recording operation.

  A display 11 and a speaker 12 are connected to the DVD recorder 1. The display 11 displays a video based on the reproduced video signal output from the output unit 6. The speaker 12 amplifies the reproduced sound signal output from the output unit 6 and emits sound.

  Next, the organizing process 93 will be described using OSDs (On-Screen Display) 911 to 915 shown in FIGS. Title A to title E in FIG. 2 represent names of recorded data (for example, names of broadcast programs). The OSD 911 in FIG. 2A displays a list of recorded data X1 that can solve the shortage of recording medium capacity when newly recording in the recording reservation process 91 when one recorded data X1 is deleted (this list is Corresponds to the first candidate of the present invention.) Represents the OSD to be displayed. In the left column of the OSD 911, names of all recorded data Y recorded on the recording medium are listed. Here, it is assumed that title A to title E are recorded.

  The “case where the recording medium shortage can be resolved when recording newly in the recording reservation process 91” is hereinafter simply referred to as “the case where the capacity shortage can be resolved”. In addition, the capacity of the recording medium that is insufficient for newly recording in the recording reservation process 91 is referred to as “insufficient capacity”.

  In the right column, if there is recorded data X1 that can solve the shortage of the capacity of the recording medium, the title is displayed. Here, only the title A corresponds to this, and FIG. 2 (A) shows it. In the right column, it is desirable to display the recording capacity of this title A (100 megabytes in FIG. 2A).

  □ in the left and right columns is a check mark for selecting recording data to be deleted. When the user selects any of the titles A to E with the cursor key (not shown) of the operation unit 8 and presses the enter key (not shown), the display is blacked out as shown by ■. When title A in the right column is selected in the state of FIG. 2A, the check mark is filled as shown in FIG. When titles B to E in the left column are selected, OSDs that are similarly painted black are output.

  FIG. 2B shows an OSD 912 for obtaining consent from the user to delete the recorded data of title A for the right column. For example, “Do you want to delete the title? YES / NO” is displayed. In this case, when “YES” is selected, the recording data of the title A is deleted.

  FIG. 3A shows an OSD 913 displayed on the display 11 when the lack of capacity of the recording medium cannot be resolved by deleting any one of the recording data Y recorded on the recording medium. It represents. If the shortage of capacity cannot be resolved, unlike the case of FIG. 2A, the shortage of the capacity of the recording medium cannot be resolved even if one piece of recorded data is deleted, so the right column is blank. On the other hand, the left column displays a list of recorded data Y recorded on the recording medium, and the selected title is highlighted. The highlighted part indicates the part currently selected by the user and can be moved by a cursor key (not shown) of the operation unit 8. When the selection of the title C is determined by a determination button (not shown) of the operation unit 8, the title C changes to an OSD 914 as shown in FIG.

  In the OSD 914 in FIG. 3B, in addition to the total capacity of recording data (title C in FIG. 3A) selected by the user (title C in FIG. 3A), other titles are recorded. A list of candidates for the recorded data X2 for solving the shortage of capacity when one data X2 is newly deleted is shown on the right side. In this example, titles A and C correspond to this.

  Note that the recording data whose selection is determined by the user from the left column of FIG. 3B corresponds to the “second candidate” of the present invention. Further, the recording data Y recorded on the recording medium may accept a plurality of selections. X2 is displayed for the first time when there is X exceeding the capacity where the total capacity V of recording data Y and the capacity of X2 are insufficient.

  FIG. 3C shows the OSD 915 of the consent screen. When the title A is selected for the right column and the check mark is filled, the OSD 912 for obtaining the user's consent to delete the recorded data is shown. For example, “Do you want to delete the title? YES / NO” is displayed. In this case, when “YES” is selected, the recording data of the title C selected by the user in the left column and the title A selected in the right column are deleted.

In the above description, when the titles A to E are selected, a square check mark is filled in. However, it may be understood that the key symbol to be checked, the entire item is inverted, highlighted, etc. Anything is fine.
Further, in OSDs 911 to 915, the candidates selected by the control unit 9 are described on the right side, but may be on the left side or may be arranged vertically. What is necessary is just to make it understand that the control part 9 selected. The following description is also the same.

FIG. 4 is used to show the flow of the organizing process 93 described with reference to FIGS. This flow is executed when the recording reservation acceptance process of the recording reservation process 91 is insufficient.
ST1 is executed by a search processing subroutine. In ST1, a candidate for recorded data X that can solve the shortage of the recording medium capacity is searched by further deleting one recorded data X from the recorded data recorded on the recording medium.

When the flow of FIG. 4 is executed for the first time, the recording data is not selected by the user on the left side of FIGS. 2 and 3 (that is, the total capacity V = 0). Therefore, in this case, the recorded data X1 having a capacity exceeding the shortage capacity is searched in ST1.
Also, when ST1 is returned from ST1 and ST51 during execution of the flow of FIG. 4 and ST1 is executed after the second time, the recording data is selected by the user on the left side of FIGS. If it is (that is, if the total capacity V> 0), the recorded data X2 exceeding the capacity obtained by subtracting V from the insufficient capacity is searched.

  The searched recording data X1 and X2 correspond to the recording data X. The recorded data searched in ST1 corresponds to the “first candidate” of the present invention.

  ST2 to ST4 are executed by an OSD processing subroutine. In ST2, it is determined whether there is a candidate X searched in ST1. If there is a candidate searched in ST1 (YES in ST1), the recorded data recorded on the recording medium is displayed together with this candidate in ST3. For example, the display is as shown in FIG. If there is no candidate searched in ST1 (NO in ST1), an OSD in which the candidate is blank is displayed in ST4. For example, the display is as shown in FIG. Then, it moves to ST51.

  Note that the display processing of ST2 to ST4 corresponds to the “display means” of the present invention.

  ST5 and ST51 are executed by a subroutine of selection reception processing. In ST5, selection of recording data to be deleted is accepted from the right column. This selection is performed by, for example, up and down cursor keys (not shown). In ST5, selection of recording data X1, X2, and Y to be deleted is accepted from both sides of the left column and the right column shown in FIGS. The selection from the left column is accepted from the recorded data recorded on the recording medium. The selection from the right column is accepted from the recorded data searched by the control unit 9 in ST1.

  ST51 accepts the same selection as ST5. In this case, since the right column is blank, selection is accepted from the recorded data Y recorded in the recording medium shown in the left column. When the selection is accepted, the check mark is painted black as shown in FIG. Thereafter, the process returns to ST1 and the search is performed again. Unless there is a candidate to be deleted (NO in ST2), ST1, ST2, ST4, and ST51 are repeated to accept selection from the left column.

  The configuration of the control unit 9 that performs the processes of ST5 and ST51 corresponds to the “selection accepting unit” of the present invention.

  In ST6, it is determined whether the recording data selected in ST5 is the searched recording data. That is, it is determined whether or not a selection has been made from the right column of FIGS. 2 (A) and 3 (B). If this determination is affirmative (YES in ST6), the process moves to ST7. If this determination is negative (NO in ST6), it means that the recording data is selected from the recording data recorded in the recording medium shown in the left column. In this case, since the total capacity V selected by the user from the left column has changed, the process returns to ST1 and the search is performed again.

  ST7 and ST8 are executed by a deletion processing subroutine. In ST7, an OSD of a consent screen asking whether the selected recording data can be deleted is output. For example, it outputs like FIG. 2 (B) and FIG. 3 (C). Thereafter, a deletion process is performed in ST8. The recording data deleted here is the recording data selected on both sides of the left column and the right column. However, if not selected in the left column, the recording data selected in the right column is deleted.

  As described above, the DVD recorder 1 of this embodiment searches for the recorded data X that can solve the shortage of capacity if one more recorded data X is deleted from the current state, and displays the recorded data (OSD 911, 914). . Therefore, the following effects occur.

(A) If the lack of capacity can be resolved by deleting one recorded data (when ST1 becomes YES in the first time), the candidate OSD 911 is displayed. If this recorded data is deleted, Users are freed from organizing work. There is no need to delete multiple recorded data by mistake.
(B) Even if one recorded data is deleted, even if the capacity shortage cannot be resolved, if the recorded data is selected, the recorded data to be deleted is indicated (ST3, OSD 914). Therefore, the user can make a prospect of which recorded data should be deleted as a set.
(C) When the user selects and corrects the recording data (NO in ST6), the search process searches for the recording data X that eliminates the shortage of capacity in accordance with the selection and correction of the user. If there is data X, it is displayed (ST3). If the user selects and corrects the recording data selected in ST7, the user can search for a more appropriate set of recording data to be deleted.
(D) As described above, since the optimum recorded data can be deleted, it is not necessary to delete the recorded data excessively.

  A process for partially accepting editing of recorded data while the OSDs of FIGS. 2A and 3B are displayed will be described with reference to FIG. This operation is performed from the operation unit 8 by a predetermined key operation, for example, left and right buttons (not shown) of the cursor key. As shown in FIG. 5, an OSD 916 that displays a sub-screen 961 for reproducing the selected title B is output. A time display bar 962 is displayed around the sub screen 961. While the screen 961 is displayed, operations such as playback, fast forward, and rewind are accepted, and selection of a start point 963 and an end point 964 is accepted with a decision key (not shown). The start point 963 and the end point 964 represent the start point and end point of the portion to be deleted in the recorded data. In the search process, when the start point 923 and the end point 924 are set, the amount is deleted, and the search is performed in ST1 of FIG. 4 in addition to the total capacity V, and the OSD of the search result is set. Output.

  As a result of this search, it is assumed that D is newly added as shown in the candidate 965. Since this candidate is output, the user can select not only the recording data of the title A having a large data capacity but also the deletion of the title D having a smaller capacity. In this way, since the recorded data can be partially deleted, the inside of the recording medium can be arranged more precisely. Therefore, it is possible to prevent unnecessary recording data from being deleted.

  Note that the configuration for performing partial deletion of recorded data as shown in FIG. 5 is not essential, but this configuration may be adopted in order to prevent the recorded data from being deleted more precisely. desirable.

  In addition, it is desirable that the search results in the right column shown in FIGS. 2, 3, and 5 are arranged from the top in order of the shortage capacity so as not to delete the recorded data unnecessarily. That is, they are arranged in order from the recording data with the smallest capacity.
