Description

  The present invention relates to a recording apparatus capable of recording moving images and audio, and more particularly to a recording apparatus that prevents recording failure due to insufficient capacity of a recording medium included in the recording apparatus.

  In recent years, digital recording apparatuses such as DVD (Digital Versatile Disk) recorders or HDD (Hard Disk Drive) recorders have been widely used as apparatuses for recording moving images and audio processed in image processing apparatuses such as televisions. ing. These digital recording apparatuses can record and manage a large amount of information on a single recording medium as compared with a conventional analog recording apparatus such as a video tape recorder.

  For this reason, a digital recording apparatus has a genre recording function for automatically recording a program corresponding to a specified genre by specifying a genre of a program to be recorded, for example. By using this function, the user can record a program of a specific genre without individually setting a recording reservation. For this reason, it is possible to perform a large amount of recording processing while omitting the trouble of recording reservation work.

  However, the digital recording apparatus has a large amount of recording data that can be recorded, but there is a problem that the user's work burden for managing the recording data tends to increase. For example, when the remaining capacity of the recording medium decreases, the user must extract only unnecessary recording data from a large amount of recording data and manually delete it.

  If the user does not perform the above deletion work, the amount of recorded data will always increase. For this reason, there is a possibility that the capacity of the storage medium becomes full before the reserved recording process of the program that the user wants to view with priority starts, and the recording process may fail. In relation to the above problem, in Patent Document 1, the remaining recordable time can be displayed and the remaining recordable time can be adjusted so that timer reservation (= recording reservation) is possible. A playback device and a remaining recordable time adjustment method are disclosed.

  When the user makes a timer reservation and the total time recorded by the timer reservation becomes longer than the usable capacity of the HDD 119, that is, the remaining recordable time, the storage device of Patent Document 1 before accepting the reservation. Inform the user to that effect. Then, processing such as changing the recording mode or deleting unnecessary titles is performed, and when the total time recorded by timer reservation on that day becomes shorter than the usable capacity of the HDD 119, that is, the remaining recordable time. Accept timer reservations.

  In Patent Document 2, when the storage capacity is almost full, a candidate to be preferentially deleted from the recorded data that has been viewed is selected, and the recorded data of the selected deletion candidate is notified to the viewing user through the monitor screen. There has been disclosed a data broadcast receiving apparatus that selects a deletion candidate again from recorded data other than the deletion candidate when the user does not want to delete the recording data indicated as the deletion candidate.

  The data broadcast receiving apparatus of Patent Document 2 examines the viewing presence / absence information stored in the memory means 11 when the free space becomes a certain value or less, and if there is already viewed program data, the corresponding data is deleted preferentially. Turn on the candidate flag. If there is no program data already viewed and there is program data being viewed, the deletion candidate flag of the corresponding data is turned on. When there is no viewed program data or currently viewed program data, the deletion candidate flag of the program data with the lowest storage priority is turned on from unviewed program data.

The control unit 9 displays a list of program data stored on the monitor screen, and when the deletion flag is turned on, the corresponding program data area is blinked on the monitor screen so that the user can receive the program data. Notify that it is a candidate for deletion.

  However, in the devices disclosed in Patent Literature 1 and Patent Literature 2, it is possible to perform notification processing when the user makes a recording reservation or when the usable capacity of the storage medium falls below a predetermined value. However, for regular recording (for example, recording reservation that repeats recording processing every Monday at a predetermined date and time), the number of times of repeated recording is not specified, so the usage capacity cannot be estimated at the time of setting the reservation, so it can be used There was a problem that it was not possible to judge whether the capacity was sufficient.

  For this reason, even if there is a shortage of usable capacity at the start of the regular recording process, the user cannot surely know the shortage of usable capacity, and the recording process fails or only the automatic deletion process must be relied upon. There was no problem. However, the automatic deletion process does not necessarily delete the recorded data that the user thinks is unnecessary, and therefore there is a risk that the recorded data that the user wanted to view without being recognized is deleted.

  In addition, even in a normal recording reservation, even if the available capacity is sufficient at the time of reservation, there is a possibility that the usable capacity decreases after the reservation and the available capacity is insufficient at the start of reserved recording. In this case, if the invention of Patent Document 2 is used, it is possible to notify the shortage of the usable capacity, but normally, it is rare that the user is near the device at the time of the scheduled recording, so the notification process means There was a problem that there was a high possibility of not.

  The present invention has been made in view of the above problems, and even when using regular recording, the user can be surely notified of the lack of usable capacity, and the lack of usable capacity has occurred after setting the recording reservation. It is an object of the present invention to provide a recording apparatus that can notify the user of insufficient usable capacity even in the case.

  In order to achieve the above object, a hard disk-equipped DVD recorder according to the present invention includes a hard disk that records moving images and / or audio as recorded data, and a display device that displays information recorded on the hard disk, excluding the recorded data. And an information output unit for outputting the recording data, a recording reservation instruction indicating the recording date and time and recording target data, and a reservation receiving unit for recording the contents of the recording reservation instruction on the hard disk as recording reservation information.

It is characterized by outputting using.

  According to this, when the capacity determination unit determines that the estimated data capacity required for scheduled recording within a predetermined period exceeds the usable capacity, the reproduced data list screen, the replicated data list screen, and the scheduled recording title An icon indicating that reservation recording is not possible is output to the list screen. Thereafter, when the capacity determination unit determines that sufficient usable capacity has been secured as a result of deletion of reproduced data or the like by the deletion unit, the display of the icon indicating that reservation recording is impossible is stopped.

  According to the present invention, when there is reproduced data that has been reproduced and exceeds a predetermined period from the recording date and time when the recording apparatus is turned on, the reproduced title list is displayed. For this reason, the user can surely know that the old recorded data that has been reproduced exists, and can easily delete the old recorded data on the list screen. As a result, the old recorded data that has been played back is left unattended and does not press on the capacity of the hard disk. In addition, it is possible to prevent a problem that the recorded data is rearranged and the burden of the work of organizing the recorded data is increased because the old recorded data and the latest recorded data are mixed.

  Further, according to the present invention, when dubbed data to a DVD medium or the like exists when the recording apparatus is turned on, a dubbed title list is displayed. Therefore, the user can surely know that dubbed recording data exists, and can easily delete dubbed data on the list screen. As a result, dubbed data is left unattended and does not press on the capacity of the hard disk. In addition, the dubbed data and the latest recorded data are mixed, and the problem that the burden of organizing the recorded data increases can be prevented.

  In addition, according to the present invention, when the recording apparatus is turned on, the estimated data capacity estimated to be used by the scheduled recording process within a predetermined period is calculated, which is sufficient to perform the scheduled recording process. Determine if there is sufficient usable capacity. If the available capacity is insufficient, the recording reservation title list is displayed and an instruction to delete the recording reservation is accepted. Therefore, the user can surely know that the recording reservation is not possible, and can easily delete the recording reservation using the recording reservation title list. As a result, the recording reservation is not failed without noticing the recording disabled state. Further, even when the available hard disk capacity decreases after the recording reservation is set and the reservation becomes impossible, it is possible to reliably notify that the recording reservation is disabled when the power is turned on. In addition, since the period for calculating the estimated data capacity is determined in advance, the estimated data capacity can be calculated for regular recording. Therefore, even when normal recording reservations and regular recording reservations are mixed, it is possible to determine whether the usable capacity is sufficient.

  Further, according to the present invention, when the deletion receiving unit does not receive the deletion instruction after the shortage of usable capacity is detected, the deleting unit displays the non-recordable title list. For this reason, it is possible to easily confirm how many recording reservations cannot be performed when the user does not issue a deletion instruction.

  According to the present invention, when the deletion unit outputs the recording reservation title list, a mark is added to the recording reservation title that is estimated to be impossible because the estimated data capacity exceeds the usable capacity. Add to the monitor. For this reason, the user can easily distinguish the recording reservation title that can be executed from the recording reservation title that cannot be executed.

  Further, according to the present invention, when the deletion receiving unit receives a deletion instruction, the deleting unit outputs the reproduced title list, the dubbed title list, and the recording reservation title list to a monitor or the like, and the user performs the above three lists. Make the display screen selectively visible. Therefore, the user can select and specify the deletion target from among the above three. For example, even when it is not desired to delete the recording reservation, it is possible to easily secure the usable capacity by deleting the reproduced data or the copied data.

  Further, according to the present invention, when it is determined that the estimated data capacity required for the scheduled recording exceeds the usable capacity, the icon indicating that the scheduled recording is impossible is displayed. For this reason, the user can surely know that the recording reservation is disabled. Further, for example, when the usable capacity is secured by deleting dubbed data or the like, it is possible to immediately know when the usable capacity sufficient for making a recording reservation can be secured.

<1-2. About the configuration of the function section>

  Here, the relationship between the functional units constituting the recording management function of the hard disk mounted DVD recorder 1 according to the first embodiment of the present invention will be described with reference to the functional block diagram of FIG.

  As shown in FIG. 1, the recording management function of the present invention has at least a reservation receiving unit 11a (= reservation receiving unit), a reproduced data extracting unit 11b (= reproduced data extracting unit), and dubbed data extraction provided in the control unit 11. Recorded data included in the hard disk 13, the unit 11 c (= replicated data extracting unit), the capacity determining unit 11 d (= capacity determining unit), the deletion receiving unit 11 e (= deleting receiving unit), and the deleting unit 11 f (= deleting unit) The recording area 13a, the management information recording area 13b, the data output unit 16, and the OSD generation unit 20 are configured.

  The reservation receiving unit 11a receives from the user a recording reservation instruction for performing a recording process at a time designated by the user by the control unit 11. The recording reservation instruction includes information including the channel of the program to be recorded, the broadcast date and time, or the recording mode (= the bit rate when recording). The user inputs such information using the operation button group 18. The reservation receiving unit 11a creates a recording reservation title list (= recording reservation information) based on the received recording reservation instruction, and records it in a management information recording area 13b described later.

  The replayed data extraction unit 11b is a recording that has been replayed (= viewed by the user) and has passed a predetermined period (for example, one month) from the recording data recorded in the recording data storage area 13a. Extract data only. Specifically, the management information of each recording data recorded in the management information recording area 13b is referred to. The management information includes information indicating the recording date and time of each recorded data and whether or not playback has been performed, and based on these information, data that has been played back and a predetermined period of time is specified. The information of the specified recording data is given to the deletion receiving unit 11e described later. Note that the length of the predetermined period may be set at the time of factory shipment of the DVD recorder 1 mounted with the hard disk, or may be set so that the user can arbitrarily change the setting later.

  The dubbed data extraction unit 11c extracts only dubbed recorded data (= duplicated on a recording medium other than the HDD such as a DVD medium) from the recorded data recorded in the recorded data storage area 13a. Specifically, the management information of each recording data recorded in the management information recording area 13b is referred to. The management information includes information indicating dubbed / undubbed of each recorded data, and dubbed data is specified based on these. The title of the specified recording data is given to the deletion receiving unit 11e described later.

  The capacity determination unit 11d reads the recording reservation information set by the user from the management information recording area 13b, and performs a recording reservation process executed based on the recording reservation information within a predetermined period (for example, within two weeks from the current time). The capacity (= estimated data capacity) of the recorded data recording area 13a estimated to be used is calculated. The capacity calculation is performed based on the recording time and recording mode in each recording reservation. Therefore, even when the recording time is the same, a recording reservation in which the recording mode is designated as a high bit rate uses a larger capacity. The calculated estimated data capacity is given to the deletion receiving unit 11e described later. Note that the length of the predetermined period may be set at the time of factory shipment of the DVD recorder 1 mounted with the hard disk, or may be set so that the user can arbitrarily change the setting later.

  When the power of the DVD recorder 1 mounted on the hard disk is turned on, the deletion accepting unit 11e performs a function provided by each functional unit with respect to the reproduced data extracting unit 11b, the dubbed data extracting unit 11c, and the capacity determining unit 11d. Order. Based on the execution results obtained from the respective function units, the OSD generation unit 20 and the data output unit 16 output a message as to whether to delete the recording data or the recording reservation to the user. Then, the state shifts to a waiting state for a deletion instruction from the user. Specifically, when it is notified from the reproduced data extraction unit 11b that reproduced data exists, when it is notified from the dubbed data extraction unit 11c that dubbed data exists, or from the capacity determination unit 11d, the usable capacity The above message is output when a shortage is notified.

  When the deletion receiving unit 11e receives an instruction to delete recorded data or recording reservation, the deletion unit 11f receives a list of reproduced data titles (= reproduced title list) and a dubbed data title list (= dubbed title list). ) Or a recording reservation title list (= recording reservation title list) using the OSD generation unit 20 and the data output unit 16. When outputting a scheduled recording title list, a mark (for example, an underline) is added to a scheduled recording title that is estimated to be unrecordable due to insufficient capacity.

  After outputting each list display screen, the deletion unit 11f shifts to a state of waiting for designation of a deletion target (for example, dubbed data). The deletion unit 11 f that has received the designation of the deletion target deletes the recording data designated as the deletion target or information related to the recording reservation from the hard disk 13.

  The deletion unit 11f outputs a non-recordable title list when the deletion reception unit 11e has not received a deletion instruction from the user after the deletion reception unit 11e enters the instruction reception state. The non-recordable title list is a list of titles of recording reservations that are presumed to be unrecordable due to insufficient capacity. Alternatively, a mark may be added only to a recording reservation title estimated to be unrecordable due to insufficient capacity.

  For example, when the OSD generating unit 20 creates video information indicating a scheduled recording title list, the title of the video that can be recorded is changed by changing the text color of the title that is estimated to be unrecordable or by underlining the title. To be able to visually distinguish the difference.

  The recorded data recording area 13 a is an area for recording moving image data and audio data input from the data input unit 14 or read from the optical disk (not shown) by the optical disk drive 17.

  The management information recording area 13b is a recording reservation title list created by the reservation receiving means 11b, management information of recording data recorded in the recording data recording area 13a, for example, recording date / time, data size, played / not played, etc. This is an area for recording information indicating.

In the example of FIG. 6, the data size of the recorded data is not shown, but the data size may be displayed and the data size may be used as a rearrangement key.

  The scheduled recording disabled icon 52 is displayed when a part or all of the recording based on the scheduled recording title list stored in the management information storage area 13b cannot be executed due to a lack of usable capacity of the hard disk 13. Note that, when the user's lack of capacity is resolved by deleting reproduced data using a cursor 53, which will be described later, the scheduled recording disabled icon 52 is hidden.

  The cursor 53 is for designating a reproduced title list that is to be deleted when the user performs an operation using the operation button group 18. The reproduced title designated by the cursor 53 is deleted from the hard disk 13 when the user presses a delete button provided in the operation button group 18, for example.

<1-4. Non-recordable title list display screen>
Here, the non-recordable title list display screen generated by the OSD generation unit 20 provided in the hard disk-equipped DVD recorder 1 according to the first embodiment of the present invention and output from the data output unit 16 is described with reference to the screen diagram of FIG. explain.

  FIG. 11 is an example of a non-recordable title list display screen of the hard disk mounted DVD recorder 1 of the present invention. As shown in FIG. 11, the non-recordable title list of the present invention is configured to include at least a list display portion 51 c and a scheduled recording disable icon 52.

  The list display unit 51c is a display unit that displays a list of reservation titles, recording date and time, recording channels, and recording modes included in the recording reservation title list recorded in the management information recording area 13b. In the example shown in FIG. 11, the recording date and time are displayed in order from the most recent reserved title, using the recording days as the rearrangement key. In the example of FIG. 11, the data size of the recording data is not shown, but the data size may be displayed and the data size may be used as a rearrangement key.

  In the list display section 51c, a recording reservation title that is estimated to be impossible due to a lack of capacity of the hard disk 13 is displayed with a mark (= underline under the title in the example shown in FIG. 11). . In the example of FIG. 11, “3. Soccer relay” and “4. Monday drama theater” indicate titles that are estimated to be unrecordable due to insufficient capacity. Note that it may be configured such that only titles that cannot be recorded are extracted and displayed, and titles that can be recorded (= “1. Monday Drama Theater” and “2. Sports News” in the example shown in FIG. 11) are not displayed.

  Since the reservation recording disabled icon 52 has the same contents as those in FIG. 6 of the present embodiment, the description thereof is omitted here.

<1-5. Display processing of played title list>
Here, the display processing of the reproduced title list in the hard disk mounted DVD recorder 1 according to the first embodiment of the present invention is shown in the block diagrams of FIGS. 1 and 2, the flowchart of FIG. 3, and FIGS. 6 and 11. This will be described with reference to the screen diagram.

  FIG. 3 is a flowchart showing a processing flow of the reproduced title list display processing of the present invention. This process is started when the deletion receiving unit 11e detects that the hard disk-mounted DVD recorder 1 is turned on. The power-on here means that the hard disk-mounted DVD recorder 1 shifts to a user operable state when the user presses a power button included in the operation button group 18. However, this processing may be performed at the time of automatic power-on at the start of reserved recording.

  In step S110, the deletion reception unit 11e that has detected the power-on gives an instruction to extract reproduced data to the reproduced data extraction unit 11b. In response to the instruction, the reproduced data extraction unit 11b extracts the reproduced data with reference to the management information recording area 13b in step S120. It is determined whether or not the extracted reproduced data exists.

  If it is determined in step S120 that reproduced data does not exist, this process ends. On the other hand, if it is determined that it exists, in step S130, the reproduced data extraction unit 11b has passed a predetermined period since each reproduced data was recorded, that is, the difference between the recorded date and the current date is a predetermined period. For example, it is determined whether or not a month is exceeded.

  If it is determined in step S130 that there is no reproduced data exceeding the predetermined period, this process is terminated. Conversely, when it is determined that there is one or more reproduced data that exceeds the predetermined period, the reproduced data extraction unit 11d notifies the deletion reception unit 11e that the reproduced data exists. Upon receiving the notification, the deletion accepting unit 11e outputs a message notifying that reproduced data exists in step S140 using the OSD generating unit 20. Then, the process shifts to a state of waiting for an instruction as to whether or not to delete the reproduced data.

  Specifically, for example, the OSD generation unit 20 is used to create a message image with a content such as “There is old recorded data that has been reproduced. Do you want to delete it? YES / NO”, and the data output unit 16 displays the message image. Output to an external monitor.

  Next, in step S150, the deletion receiving unit 11e determines whether or not an instruction to delete reproduced data has been received. The reproduction data deletion instruction is given, for example, when the user performs an operation of selecting “YES” using the operation button group 18 in a state where the message created by the OSD generation unit 20 is displayed. Issued to.

  In step S150, when the deletion instruction of the reproduced data is not accepted, the deletion unit 11f displays the non-recordable title list shown in FIG. 11 for a predetermined time in step S155, and then ends this process. For example, this corresponds to the case where “NO” is selected for the above message or the case where a predetermined time has elapsed since the transition to the standby state.

  Conversely, when receiving an instruction to delete reproduced data, the deletion accepting unit 11e notifies the deleting unit 11f of management information of recorded data that has been reproduced and has exceeded a predetermined period. In step S160, the deletion unit 11f that has received the notification creates the reproduced title list shown in FIG. 6 using the OSD generation unit 20 based on the notified management information of the reproduced data, and outputs the data. Output from the unit 16. Then, it enters an instruction waiting state in which the reproduced title to be deleted is received from the outside.

  Next, in step S170, the deletion unit 11f determines whether an instruction for a reproduced title to be deleted has been received. Note that the instruction of the reproduced title to be deleted is issued, for example, when the user operates the operation button group 18 to move the cursor 53 shown in FIG. 6 and presses the enter button.

  In step S170, if an instruction for a reproduced title to be deleted is not received, for example, if the instruction standby state continues for one minute or longer, the deletion unit 11f displays the unrecordable title list shown in FIG. 11 for a predetermined time in step S155. Then, this process is terminated. Conversely, when receiving an instruction for a reproduced title to be deleted, the deleting unit 11f deletes management information and recorded data related to the instructed reproduced title from the hard disk 13 in step S180, and ends this processing.

  It is also possible to select a plurality of reproduced titles to be deleted and delete them at once. Further, when a sufficient usable capacity is secured for performing the recording reservation by the deletion process, the reservation recording disabled icon shown in FIG. 6 is hidden.

Here, a dubbed title list display screen created by the OSD generation unit 20 included in the hard disk mounted DVD recorder 1 according to the second embodiment of the present invention and output from the data output unit 16 will be described with reference to the screen diagram of FIG. explain.

  FIG. 7 is an example of a dubbed title list display screen of the hard disk mounted DVD recorder 1 of the present invention. As shown in FIG. 7, the dubbed title list display screen of the hard disk-equipped DVD recorder 1 of the present invention is configured to include at least a list display section 51b, a reserved recording disabled icon 52, and a cursor 53.

  The list display unit 51b is a display unit that displays a list of titles, recording dates and times, recording channels, and recording modes of dubbed data recorded in the recording data recording area 13a. In the example shown in FIG. 7, the recording days are displayed in order from the oldest recording data using the recording days as the rearrangement key. In the example of FIG. 7, the data size of the recording data is not shown, but the data size may be displayed and the data size may be used as a rearrangement key.

  The reserved recording disabled icon 52 and the cursor 53 have the same contents as those in the first embodiment, and thus description thereof is omitted here.

<2-4. Non-recordable title list display screen>
Since it is the same content as Embodiment 1, description is abbreviate | omitted here.

<2-5. Display processing of dubbed title list>
Here, the display process of the dubbed title list in the hard disk mounted DVD recorder 1 according to the second embodiment of the present invention is shown in the block diagrams of FIGS. 1 and 2, the flowchart of FIG. 4, and FIGS. 7 and 11. This will be described with reference to the screen diagram.

  FIG. 4 is a flowchart showing a process flow of the dubbed title list display process of the present invention. This process is started when the deletion receiving unit 11e detects that the hard disk-mounted DVD recorder 1 is turned on. The power-on here means that the hard disk-mounted DVD recorder 1 shifts to a user operable state when the user presses a power button included in the operation button group 18. However, this processing may be performed at the time of automatic power-on at the start of reserved recording.

  In step S210, the deletion acceptance unit 11e that has detected the power-on gives an instruction to extract dubbed data to the dubbed data extraction unit 11c. Upon receiving the instruction, the dubbed data extraction unit 11c extracts dubbed data with reference to the management information recording area 13b in step S220. Then, it is determined whether or not the extracted dubbed data exists.

  If it is determined in step S220 that the extracted dubbed data does not exist, this process ends. Conversely, when it is determined that the data exists, the dubbed data extraction unit 11c notifies the deletion reception unit 11e that dubbed data exists. Receiving the notification, the deletion accepting unit 11e outputs a message notifying that dubbed data exists in step S230 using the OSD generating unit 20. Then, the process shifts to a state of waiting for an instruction as to whether to delete dubbed data.

  Specifically, for example, the OSD generation unit 20 creates a message with the content “There is dubbed recorded data. Do you want to delete it? YES / NO”, and the data output unit 16 outputs the above message to an external monitor or the like To do.

  Next, in step S240, the deletion reception unit 11e determines whether an instruction to delete dubbed data has been received. The dubbed data deletion instruction is given, for example, when the user performs an operation of selecting “YES” using the operation button group 18 in a state where the message created by the OSD generation unit 20 is displayed. Issued to.

  If no deletion instruction for dubbed data is received in step S240, the deletion unit 11f displays the non-recordable title list shown in FIG. 11 for a predetermined time in step S245, and then ends this process. For example, when “NO” is selected for the message, or when a predetermined time has elapsed since the transition to the standby state.

  Conversely, when receiving an instruction to delete dubbed data, the deletion receiving unit 11e notifies the deletion unit 11f of management information on dubbed data. In step S250, the deletion unit 11f that has received the notification creates the dubbed title list shown in FIG. 7 using the OSD generation unit 20 based on the notified management information of the dubbed data, and outputs the data. Output by the unit 16. Then, a dubbed title to be deleted is received from the outside, and an instruction waiting state is set.

  Next, in step S260, the deletion unit 11f determines whether an instruction for a dubbed title to be deleted has been received. The instruction of the dubbed title to be deleted is issued, for example, when the user operates the operation button group 18 to move the cursor 53 shown in FIG. 7 and presses the enter button.

  If an instruction for a dubbed title to be deleted is not received in step S260, for example, if the instruction standby state continues for one minute or longer, the deletion unit 11f displays the unrecordable title list shown in FIG. 11 for a predetermined time in step S245. Then, this process is terminated. On the contrary, when receiving an instruction for a dubbed title to be deleted, the deletion unit 11f deletes management information and recorded data related to the instructed dubbed title from the hard disk 13 in step S270 and ends this processing.

  It is also possible to select a plurality of dubbed titles to be deleted and delete them all at once. Further, when a sufficient usable capacity is secured for performing the recording reservation by the deletion process, the reservation recording disabled icon shown in FIG. 7 is hidden.

Here, the recording reservation title list display screen created by the OSD generation unit 20 provided in the hard disk-equipped DVD recorder 1 according to the third embodiment of the present invention and output from the data output unit 16 will be described with reference to the screen diagram of FIG. explain. The recording reservation title list is created in advance by the reservation receiving means 11 and recorded in the management information recording area 13b.

  FIG. 8 shows an example of a recording reservation title list display screen of the hard disk mounted DVD recorder 1 of the present invention. As shown in FIG. 8, the recording reservation title list display screen of the hard disk-equipped DVD recorder 1 of the present invention is configured to include at least a list display portion 51 c, a reservation recording disabled icon 52, a cursor 53, and a tab 54. Has been.

  Since the list display unit 51c has the same contents as those in FIG. 11 of the first embodiment, the description thereof is omitted here. Further, since the reservation recording disabled icon 52 and the cursor 53 have the same contents as those in the first embodiment, the description thereof is omitted here. The tab 54 is for switching the recording reservation title list display screen shown in FIG. 8 to the reproduced title list display screen shown in FIG. 9 and the dubbed list display screen shown in FIG. The user can arbitrarily switch between the three screens by performing a tab switching operation (selecting an active tab) using the operation button group 18.

  FIG. 9 shows a screen when the “Played” tab is activated, and FIG. 10 shows a screen when the “Dubbed” tab is activated. Except that the tab 54 is provided, the contents are the same as those in FIG. 6 according to the first embodiment and FIG. 7 according to the second embodiment, and thus detailed description thereof is omitted here.

<3-4. Non-recordable title list display screen>
Since it is the same content as Embodiment 1, description is abbreviate | omitted here.

<3-5. Display processing of the scheduled recording title list>
Here, the display processing of the recording reservation title list in the hard disk mounted DVD recorder 1 according to the third embodiment of the present invention is shown in the block diagrams of FIGS. 1 and 2, the flowchart of FIG. 5, and FIGS. This will be described with reference to the screen diagram.

  FIG. 5 is a flowchart showing a processing flow of the recording reservation title list display processing of the present invention. As shown in FIG. 5, this process is started when the deletion receiving unit 11e detects that the hard disk-mounted DVD recorder 1 has been turned on. The power-on here means that the hard disk-mounted DVD recorder 1 shifts to a user operable state when the user presses a power button included in the operation button group 18. However, this processing may be performed at the time of automatic power-on at the start of reserved recording.

  In step S310, the control unit 11 that has detected the power-on performs the reproduced title list display process described in the first embodiment. That is, the processing flow shown in FIG. 3 is performed. After the processing flow of FIG. 3 is completed, the control unit 11 performs the dubbed title list display process shown in the second embodiment in step S320. That is, the processing flow shown in FIG. 4 is performed.

  After the processing flow in FIG. 4 is completed, the deletion accepting unit 11e instructs the capacity determining unit 11d to perform the capacity determining process. In step S330, the capacity determination unit 11d that has received the instruction reads the recording reservation information from the management information recording area 13b, and extracts the recording reservation information within a predetermined period, for example, within two weeks from the current time. In step S340, the capacity determination unit 11d calculates the data capacity (= estimated data capacity) used by the recording process executed based on the extracted recording reservation information.

  Further, the capacity determination unit 11d compares the calculated estimated data capacity with the usable capacity of the hard disk 13 in step S350. If the usable capacity of the hard disk 13 is larger than the estimated data capacity, this process is terminated. On the contrary, when the usable capacity of the hard disk 13 is smaller than the estimated data capacity, the capacity determination unit 11d notifies the deletion reception unit 11e that the usable capacity is insufficient.

  Upon receiving the notification, the deletion accepting unit 11e outputs a message for notifying the available capacity shortage using the OSD generating unit 20 in step S360. Then, it shifts to a state of waiting for an instruction as to whether to delete the recording data or the recording reservation.

  Specifically, for example, the OSD generation unit 20 says “The available capacity of the HDD is low. Please delete the recording reservation or unnecessary recording data. Do you want to delete the recording reservation / recording data? YES / NO "is created, and the data output unit 16 outputs the message to an external monitor or the like.

  Next, in step S370, the deletion reception unit 11e determines whether a recording reservation / recording data deletion instruction has been received. Note that the recording reservation / recorded data deletion instruction is performed, for example, when the user selects “YES” using the operation button group 18 in a state where the message generated by the OSD generation unit 20 is displayed. Issued in some cases.

  If no recording reservation / recording data deletion instruction has been received in step S370, the deletion unit 11f displays the non-recordable title list shown in FIG. 11 for a predetermined time in step S375, and then ends the process. For example, when “NO” is selected for the message, or when a predetermined time has elapsed since the transition to the standby state.

  Conversely, when receiving a recording reservation / recorded data deletion instruction, the deletion receiving unit 11e gives the deletion unit 11f an instruction to display the recording reservation title list / reproduced title list / dubbed title list. Upon receipt of the above instruction, the deletion unit 11f creates each title list shown in FIGS. 8 to 10 using the OSD generation unit 20 and outputs it using the data output unit 16 in step S380. Then, it enters an instruction waiting state for accepting a recording reservation or a title of recording data to be deleted. In this state, the user can switch between the screens shown in FIGS.

  If display of the reproduced title list is selected in step S380, the deletion unit 11f displays the reproduced title list shown in FIG. 9 in step S390. In step S400, designation of a reproduced title to be deleted is accepted. Then, after the management information and recorded data related to the received reproduced title are deleted from the hard disk 13, the process proceeds to step S450 described later.

  If the display of the dubbed title list is selected in step S380, the deletion unit 11f displays the dubbed title list shown in FIG. 10 in step S410. In step S420, designation of a dubbed title to be deleted is accepted. Then, after deleting the management information and recorded data related to the accepted dubbed title from the hard disk 13, the process proceeds to step S450 described later.

  When the display of the recording reservation title list is selected in step S380, the deletion unit 11f displays the recording reservation title list shown in FIG. 8 in step S430. In step S440, designation of a recording reservation title to be deleted is accepted. Then, after deleting the recording reservation information related to the received recording reservation title from the management information recording area 13b, the process proceeds to step S450 described later.

  In step S450, the deletion unit 11f instructs the capacity determination unit 11d to perform capacity determination processing. Upon receiving the instruction, the capacity determination unit 11d compares the estimated data capacity used by the scheduled recording process with the usable capacity of the hard disk 13 within a predetermined period, as in step S350.

  If the usable capacity of the hard disk 13 is smaller than the estimated data capacity, the process proceeds to step S380 again. Conversely, if the usable capacity of the hard disk 13 is larger than the data capacity used by the scheduled recording process, the deletion unit 11f hides the scheduled recording disabled icon 52 in step S460, and then ends this process.
