  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows an example of a video recording / playback apparatus (recorder apparatus) to which an embodiment of the present invention can be applied. In each element described below, an element called “module” may be realized by hardware, or may be realized by software using a CPU (microcomputer) or the like. May be.

  The video recording / playback apparatus 1 selects a program that can be acquired via an antenna, receives a program from the program received by the tuner 3, and performs control for displaying the information requested by the user. When the main control module (main control block) 5 to be executed and the video display device (monitor device) 101 connected as an external device process the program received by the tuner 3 so as to be displayable, and there is a request from the user, A recording / reproducing signal processing module 7 for recording (recording) on a recording unit described later is included. The monitor device 101 is called a full high-definition (full HD) with an aspect ratio (horizontal screen length to vertical screen length) of 16: 9, for example, with 1920 pixels in the horizontal direction and 1080 pixels in the vertical direction. Digital broadcasting can be displayed. As will be described later, the main control module 5 is also connected to a memory module 9 for storing various information.

  The tuner 3 selects an arbitrary channel of satellite broadcast received by a satellite antenna (not shown). Similarly, an arbitrary channel of terrestrial digital broadcast or terrestrial analog broadcast received by a terrestrial antenna (not shown) is selected. Today, there are cases where two or more tuners are prepared for satellite broadcasting and terrestrial broadcasting, respectively, and there are cases where a program of a plurality of channels can be selected. Also, when a multi-tuner in which a plurality of tuner modules are integrated is installed, a program of a plurality of channels can be selected in the same manner.

  In other words, the tuner 3 can receive a program (title) of an arbitrary channel of a public broadcast represented by terrestrial analog / digital or the like and a public satellite broadcast wave supplied via a broadcast satellite. A digital broadcast in the form of a transport stream (hereinafter referred to as “TS”) can be received. Although not described in detail, the tuner 3 can also receive limited content supplied from a provider or a distribution station (regional network base station) via an optical cable, for example.

  Although not described in detail, the main control module 5 includes a central processing unit (CPU) or a main processing unit (MPU), and receives a user operation by a user operation input unit 11 and a remote terminal (remote control) 13 that receive a user's direct operation. Connected to the remote control receiving unit 15, receives various user operations (control inputs) described below, outputs corresponding commands, and controls the operation of each unit of the video recording / reproducing apparatus 1. Although not shown, the user operation input unit 11 receives an operation input (from the user) that is directly instructed by an operation button group provided on the main body of the video recording / reproducing apparatus 1. For example, a user operation input unit 11 can input a playback instruction by a playback (PLAY) button or a recording instruction by a recording (REC) button normally provided in the main body of the video recording / playback apparatus 1. Further, the remote control receiver 15 selects control information instructed by the user via the remote control terminal 13, for example, selection of broadcast waves / inputs to be received (acquired) via the tuner 3, and the recording / playback signal processing module 7. Recording process and recording medium, that is, a title (content) to be deleted or dubbed (or moved) from the optical disk D set in the HDD (Hard Disk Drive, large capacity recording device 17 or disk drive device 19) described below Is received, and a corresponding command is input to the CPU or MPU, that is, the main control block 5.

  Although not described in detail, the recording / playback signal processing module 7 includes at least a video encoder module, a video decoder module, an audio encoder module, an audio decoder module, and the like. Although not described in detail, the encoder module converts (encodes) an input analog signal (video (video) / audio (sound)) into a digital signal. For example, MPEG (Moving Picture Experts Group) -2 Alternatively, signal compression based on MPEG-4 (H.264-AVC) or the like is widely used. Although not described in detail, it goes without saying that the decoder module decodes a digital signal compressed into MPEG-2 or MPEG-4 (H.264-AVC) or the like.

  The recording / playback signal processing module 7 is also accommodated in the optical disc D by setting, for example, the DVD standard or an optical disc (detachable information recording medium) D having a higher recording density than the DVD standard. Is connected to a disk drive device 19 capable of reproducing the recorded information or recording a program (title or content) supplied from the HDD 17 or the tuner 3, that is, video data and audio data. When the optical disc D is a DVD standard, the recording capacity is 4.7 Gbytes (standard image quality can be recorded for about 2 hours, and “TS” can be recorded for about 40 minutes). The recording capacity of the HDD 17 is, for example, 250 to 1000 Gbytes, and video data and audio data of about 1000 hours can be recorded at maximum by changing the recording rate. Although the title (content) held in the HDD 17 is not described in detail, a hard disk device (HDD-x) of another video recording / playback device connected to a home network or server, or the video recording / playback device 1 Needless to say, it may be a hard disk device (additional HDD) additionally installed.

  The memory module 9 is not described in detail, but a main memory (SDRAM) functioning as a work memory, a ROM holding a program for operating any element of the main control module 5 or the video recording / reproducing apparatus 1, and not described in detail. It includes a non-volatile memory (NVM) that holds information such as a reservation date and time, a recording / dubbing type, a length (start time / end time), a channel (ch), and a rate reserved in the dubbing reservation control unit.

  The main control module 5 also outputs video to the monitor device 101 connected to the outside or an external video output terminal not described in detail to the OSD (On Screen Display) display output module 21, that is, the user operation input unit 11 or the remote control. For example, a selection screen or an operation screen corresponding to an operation input (control signal), a command for selecting or switching a channel (tuner), a collective deletion instruction described below, or the like input via the receiving unit 15 Is output as an OSD display output that is superimposed on the playback video of the title (content) for which the display output is currently output at a predetermined transmittance. The display output of the OSD display output module 21 is a normal video signal (during playback) in a thin “semi-transparent” state to a dark “semi-transparent” state on a normal video display according to the transmittance parameter (α blending). Video signal of the original density of the title or content).

  That is, the OSD display output output from the OSD display output module 21 is a playback video signal of a title (content) by the synthesis module 23 in a state where a part of the playback video is transmitted so that the playback video becomes a background image. Is superimposed on the output. Note that the title (content) on which the output from the OSD display output module 21 is superimposed is from an arbitrary “ch” program selected by the tuner 3 and from the optical disc D reproduced by the disc drive device 19. Needless to say, it may be a reproduced video or a title (content) held in the HDD 17.

  Hereinafter, a method for realizing the embodiment of the present invention will be described in more detail.

  The main control module 5 includes, in addition to the CPU or MPU described above, a recorded program deletion mode reception module 5a and a recorded program deletion mode reception module 5a that receive setting (activation) of a deletion mode used for deletion of a recorded program based on a user operation. When the delete mode setting (startup) is accepted, the program list display module 5b and the program list display module 5b to be edited display a list (list) of programs currently recorded or an “editing navigation” screen. A recording medium recordable time calculation module 5c for calculating the (remaining) recordable time of the recording medium when an instruction to delete an arbitrary number of titles (contents) is instructed from the displayed program list, and an edit target program list display module 5b. Thumbnail image displayed in the displayed program list or “Edit Navi” screen When deletion of any number of titles (contents) is instructed (selected), the total recording time of the program instructed (selected) as the deletion target, that is, the occupation ratio of the recording information to be deleted to the recording capacity of the recording medium It includes a deletion selection program recording time calculation module 5d to be calculated, and a recordable time display module 5e before and after deletion that displays the remaining free space (recordable time) that is a change in the occupation ratio of the recording medium before and after deletion.

  Although the HDD 17 depends on the recording capacity and the rate of recorded titles (contents), normally, several hundred titles (contents) can be recorded. When the recorded programs are simply displayed as a list, It takes a lot of time to search for the target title (content). For this reason, it is preferable to group the recorded programs or programs to be recorded in the future according to the attributes of the programs or classifications set by the user, and prepare and sort virtual containers called “folders”. In addition, based on the concept of “trash can”, the title (content) to be deleted, which was instructed to be deleted by the user, is temporarily saved, and “trash can (folder)” that enables deletion of all items (collective deletion) By preparing, when a certain amount of recording capacity is required for a long time recording or high-quality recording suddenly, it becomes easy to secure the remaining recording capacity in a case where the recording capacity is needed.

  When a “deletion key” (not shown) of the remote control terminal 13 is turned on, the recorded program deletion mode reception module 5a detects that there is a request to delete an arbitrary number of titles (contents), and issues a deletion mode activation request. The reception and edit target program list display module 5b is requested to display the “editing navigation” (collective deletion) screen as shown in FIG. Even when the “delete key” of the remote control terminal 13 is not turned on, for example, “menu” in the button display displayed at the bottom of the video of the title (content) currently reproduced on the monitor device 101, for example. The display is selected by operating the cursor keys on the remote control terminal 13 (arrow keys for inputting a command capable of instructing movement of the cursor (focus) in four directions of “up”, “down”, “left”, and “right”). When the determination key is turned on, the recorded program deletion mode reception module 5a also receives a deletion mode activation request.

  The editing target program list display module 5b corresponds to the “editing navigation” (collective deletion) screen as shown in FIG. 2A when the recording program deletion mode reception module 5a requests activation of the deletion mode. A display signal capable of outputting an image to be generated is generated. The display example shown in FIG. 2A is naturally a display signal at the output end of the synthesizing module 23, and it goes without saying that the display example is displayed on the monitor device 101.

  When an arbitrary title (content) is specified as a deletion target by operating the cursor key of the remote control terminal 13 on the “editing navigation” (collective deletion) screen shown in FIG. The (time remaining) recordable time of the current recording medium is obtained by the time calculation module 5c, and is displayed in the form of a character string in the lower center of the screen displayed on the monitor device 101. Further, the occupation ratio of the recording information to be deleted with respect to the recording capacity of the recording medium is obtained by the deletion selection program recording time calculation module 5d, and is graphically displayed at the lower center of the screen displayed on the monitor device 101. . FIG. 2A shows an example in which the above-mentioned “folder”, “trash box (folder)”, and five titles (parts) not yet sorted into folders are displayed. This is a state in which deletion is instructed to any part ([005] in the example of the figure) displayed between the title column of “Navi” (collective deletion) and the “deletion target” column in the lower row. The title [0001] corresponding to the part [005] is displayed in the “deletion target” column.

More specifically, the remaining recordable time of the current recording medium obtained by the recording medium recordable time calculation module 5c is, for example, as “time display” as shown in FIG.
In the case of <<< target to delete:>
When selecting only the original title or a mixture of the original title and playlist,
[TS1 / TS2 (about 4 hours 54 minutes → about 5 hours 10 minutes)]
[RE [Setting 3] (about 24 hours and 16 minutes → about 25 hours and 37 minutes)]
As shown, the recordable time that is increased when the deletion target selected as the deletion candidate is deleted is displayed. In this case, in consideration of the recording mode, for example, when “TS1” / “TS2” and the same recording rate as the currently selected title (content) are used, for example, “VR”, “SP”, “ The recordable time is calculated and displayed according to a condition (recording rate) such as 4.6 ". Although not shown in the drawing, the recordable time at the changed recording rate is displayed by changing the recording rate (used for recording) on the reservation (registration) screen for registering reserved recording or the recording setting screen. Is possible. Further, by changing the deletion candidate, the remaining recordable time is displayed at the recording rate used for recording (recording) the deletion candidate.

However, when only the playlist is deleted, the remaining recordable time is substantially the same as before the deletion, so when only the playlist is selected, the above display is
[TS1 / TS2 (approximately 4 hours 54 minutes → approximately-time-minutes)]
[RE [Setting 3] (About 24 hours and 16 minutes → About-hours-minutes)]
In this way, the time predicted to increase when the deletion target selected as the deletion candidate is deleted is not displayed (for example, “-” display is displayed). In order to clearly indicate that the remaining recordable time does not increase, the same number (time) as the left side of → may be displayed on the right side of →.

Further, “<< deletion target: none >>”, that is, until the deletion candidate is instructed, as in the case where only the playlist is deleted,
[TS1 / TS2 (approximately 4 hours 54 minutes → approximately-time-minutes)]
[RE [Setting 3] (About 24 hours and 16 minutes → About-hours-minutes)]
As described above, the time that is expected to increase when the deletion target selected as the deletion candidate is deleted is not displayed (for example, “-” display is displayed).

  On the other hand, for the remaining recordable capacity of the recording medium obtained by the deletion selected program recording time calculation module 5d, a “disc capacity display” GUI (Graphical User Interface) is displayed in the lower part of the center of the display screen.

That is, in FIG. 2B, for the same time as the “time display” described above, for example,
In the case of <<< object to be deleted:>
When only the original title is selected or when the original title and playlist are mixed, the remaining recordable time is shown schematically as the disc capacity (usage or occupancy) after the deletion. An indicator (GUI) is shown.

  Specifically, a display in which the “A” portion is increased in the remaining capacity indicator of FIG. 2B is displayed so that the remaining recordable time of the current recording medium obtained by the recording medium recordable time calculation module 5c can be recognized. Is done. The display for increasing the “A” portion, that is, the increased portion A is calculated by the recordable time display portion 5e before and after the deletion.

  However, when only the playlist is deleted, the remaining recordable time is substantially the same as before the deletion, so when only the playlist is selected, the remaining capacity indicator display described above is substantially Does not change.

  It should be noted that “<< removal target: none >>”, that is, until the deletion candidate is instructed, the display of the remaining capacity indicator described above is substantially changed as in the case where only the playlist is deleted. It goes without saying that you don't.

  FIGS. 3A and 3B show an example of a screen display different from the “editing navigation” (collective deletion) screen shown as an example in FIGS. 2A and 2B. Note that a part of the operations substantially the same as those in the “editing navigation” (collective deletion) screen shown in FIG. 2A and FIG. 2B are omitted.

  As shown in FIG. 3A, for example, a title (content) that has already been recorded is currently being reproduced on the monitor device 101 at any timing when the title (content) in an arbitrary folder is being reproduced. Of the button displays displayed at the bottom of the title (content) video, for example, the “menu” display is the four cursor keys (“up”, “down”, “left”, “right”) of the remote control terminal 13. Is selected by an operation of an arrow key for inputting a command capable of instructing movement of the cursor (focus), and the determination key is turned on, whereby the recorded program deletion mode reception module 5a receives a deletion mode activation request, The “viewing navigation” (title thumbnail list) screen display is not described in detail by the editing target program list display module 5b. The radical 113, (display output is outputted to the synthesis module 23) is displayed.

  Hereinafter, when an arbitrary title (content) is selected as a selection candidate (selection target) via the remote controller 13, the selected title (content) is “original title only or original title and playlist are mixed. In the case of “selected”, for example, a warning screen informing that “when“ Delete ”is executed, the title cannot be restored” is displayed in a pop-up in the approximate center of the screen (display).

  In the warning screen, the “remaining recordable time of the recording medium” and the current “remaining recordable time of the recording medium” obtained by the recording medium recordable time calculating module 5c and the deletion selected program recording time calculating module 5d are displayed. As for the remaining recordable capacity of the recording medium determined by the above, a pictograph-like remaining capacity indicator indicating that the current “remaining recording capacity of the recording medium” increases after erasure is displayed simultaneously.

Note that the remaining recordable time of the recording medium is the same as described with reference to FIG.
[TS1 / TS2 (about 4 hours 54 minutes → about 5 hours 10 minutes)]
[RE [Setting 3] (about 24 hours and 16 minutes → about 25 hours and 37 minutes)]
As shown, the recordable time that is increased when the deletion target selected as the deletion candidate is deleted is displayed. In this case, in consideration of the recording mode, for example, “TS1” / “TS2” and, for example, the time when using the same recording rate as the currently selected title (content) are calculated and displayed.

  Further, the remaining recordable capacity of the recording medium obtained by the deletion selected program recording time calculation module 5d is displayed by a “disc capacity display” GUI (Graphical User Interface) in the approximate center of the warning screen display.

  That is, although an example is shown in FIG. 2B, the “recording capacity” obtained by the deletion selected program recording time calculation module 5d, that is, the remaining recording capacity of the current recording medium obtained by the recording medium recordable time calculation module 5c can be recorded. In order to be able to recognize the time as an increase in “recording capacity”, the remaining capacity indicator (GUI) in FIG. 2B displays a display for increasing the “A” portion, that is, an increased portion A. As described above, the increased portion A is calculated by the recordable time display unit 5e before and after the deletion.

  However, when only the playlist is deleted, the remaining recordable time is substantially the same as that before the deletion, so when only the playlist is selected, as shown in FIG. , “When the“ delete ”is executed, the title cannot be restored”, only a warning screen pop-up is displayed.

  5 to 7 show an example in which the deletion of the title (content) in the folder described with reference to FIGS. 3A and 3B is applied to a specific folder, for example, “trash box (folder)”. Note that a part of the operations substantially the same as those in the “editing navigation” (collective deletion) screen shown in FIG. 2A and FIG. 2B are omitted.

  For example, when the title (content) moved in the “trash box” folder is only the original title (not including the playlist) as shown in FIG. (Start instruction) is received by the recorded program deletion mode reception module 5a, a display output for displaying the “editing navigation” (trash list) screen is output from the editing target program list display module 5b to the synthesis module 23, and the monitor device 101 In the same manner as described with reference to FIG. 3A, a warning screen for notifying that “the title cannot be restored if“ deletion ”is executed” and “disc capacity display” are displayed on the display unit. (See FIG. 5 (b)).

  If the title (content) moved in the “trash box” folder includes an original title and a playlist (a playlist is mixed) as shown in FIG. When the activation request (deletion start instruction) is received by the recorded program deletion mode reception module 5a, a display output for displaying the “editing navigation” (trash box list) screen is output from the editing target program list display module 5b to the synthesis module 23. In the same manner as described above, a warning screen and a “disc capacity display” are displayed on the display unit of the monitor device 101 informing that “the title cannot be restored when“ delete ”is executed” ( (Refer FIG.6 (b)).

  On the other hand, when the title (content) moved in the “trash box” folder includes only the playlist (not including the original title) as shown in FIG. When the request (deletion start instruction) is received by the recorded program deletion mode reception module 5a, the title is restored when “Delete” is executed from the editing target program list display module 5b to the display unit of the monitor device 101. Only a warning screen informing that “cannot be performed” is displayed (see FIG. 7B).

  This is possible. By deleting the title recorded on the recording medium, or by deleting an arbitrary number of titles suggested to be deleted in advance, how big is the recording rate used for recording the recording target The user can easily grasp whether the (time) title can be recorded.

  FIG. 4 shows an example of the embodiment shown in FIGS. 3A and 3B and FIGS. 5 to 7 in terms of software.

  In FIG. 4, when the recorded program deletion mode reception module 5a receives a deletion mode activation request (block [01-YES]), the editing target program list display module 5b stores the deletion mode activation request in the folder or For all titles (contents) held by the recording device (HDD 17 or optical disk D in the disk drive unit 17), a list display of thumbnails or thumbnails and title (program) names is generated (block [02]).

  Thereafter, counter [i] is cleared ([i = i ← 0] is set in the counter) (block []), and the first deletion candidate (deletion target) title is designated (input) (block [04 -YES]), the reduction scheduled time X is calculated by “X = (i + 1)” (block [05]).

  Subsequently, the recordable scheduled time (free capacity (usage amount)) Yb after the deletion is calculated from the remaining recording time (recorded capacity (occupancy)) Ya of the recording medium and the scheduled deletion time X by “Yb = Ya + X”. (Block [06]).

  Thereafter, 1 is added to the counter [i] ([i = i + 1] is set), and the recordable scheduled time (free space (usage)) Yb after the deletion is obtained until the deletion candidate input is completed (block) [04] to [07]). Note that the obtained free space is the output converted into the recordable time when using the recording rate applied to the designated or deletion candidate title (content) and the specific compression condition (such as “TS”). Is applied (2 or more).

  In this way, by deleting deletion candidate titles recorded on the recording medium, or deleting any number of deletion candidate titles (groups) that are suggested to be deleted in advance, At the recording rate used for recording, the user can easily grasp how long a title (recording size) can be recorded.

  In the embodiment shown in FIG. 4, it goes without saying that the playlist is excluded.

  As described above, according to one embodiment of the present invention, a title recorded on a recording medium is deleted, or an arbitrary number of titles suggested to be deleted in advance is deleted. Thus, the user can easily grasp how large (time) the title can be recorded at the recording rate used for recording.

  In particular, since the remaining recording capacity can be visually confirmed as the usage amount (occupancy or free capacity) of the recording apparatus, the operability for the user is improved.

  Further, the remaining recording capacity at the same recording rate as the title (content) of the deletion candidate can be grasped, and the convenience for the user is improved.

  In addition, this invention is not limited to each embodiment mentioned above, A various deformation | transformation or change is possible in the range which does not deviate from the summary in the stage of the implementation. In addition, the embodiments may be implemented by appropriately combining them as much as possible, or by deleting a part thereof. In that case, various effects resulting from the combination or deletion can be obtained.

Recording / playback device.   The video recording / reproducing apparatus according to claim 1, wherein the time calculation module stops calculation of the recordable time when a program whose recordable time does not increase is instructed as a deletion candidate as a result of the deletion.   The video according to claim 1, wherein the time calculation module includes a program whose recordable time does not increase as a result of the deletion, and cancels the calculation of the recordable time when a deletion candidate title is instructed. Recording / playback device.   2. The video recording / reproducing apparatus according to claim 1, wherein the capacity display module displays a free capacity that increases in a recording medium when a deletion candidate program is deleted.   6. The video recording / reproducing apparatus according to claim 5, wherein the capacity calculation module stops the calculation of the free capacity when a program whose recordable time does not increase as a result of the deletion is instructed as a deletion candidate.   6. The video recording according to claim 5, wherein the capacity calculation module includes a program whose recordable time does not increase as a result of the deletion, and cancels the calculation of a free capacity when a deletion candidate title is instructed. Playback device. Accept activation of delete mode,
List all programs on a recording medium or a pre-sorted specific group,
For a program that is instructed (input) as a deletion candidate (deletion target) among the programs being displayed in a list, the recordable time X that occurs when the program is deleted is calculated by “X = (i + 1)”.
The recordable scheduled time (free capacity (usage amount)) Yb after the deletion is calculated from the remaining recording time (recorded capacity (occupancy)) Ya of the recording medium and the generated recordable time X by “Yb = Ya + X”. A method for controlling a video recording / reproducing apparatus. Displays a list or group of programs that can be deleted,
When an individual program included in an arbitrary program or group in the displayed list is instructed to be a deletion candidate, the recordable time secured on the recording medium when the specified program is deleted is set. Calculate
When an individual program included in an arbitrary program or group in the displayed list is instructed to be a deletion candidate, when the specified program is deleted, the recordable capacity secured on the recording medium is increased. Calculate
The recordable capacity calculated by the capacity calculation module when an individual program included in an arbitrary program or group in the displayed list is instructed to be a deletion candidate or when the designated program is deleted A method for controlling a video recording / reproducing apparatus, characterized in that the degree of increase is output in a displayable manner.
