Description

  The present invention relates to a video recording / reproducing apparatus capable of notifying a user of whether or not duplication (dubbing) / movement (move) is possible based on an inserted recording medium.

  As a device that can play back video (including audio information) provided using an optical disc as a recording medium, a player device that plays back video from a DVD standard optical disc and a recorder device that can record video information on the same optical disc are put into practical use. It has been a long time.

  Today, the HD (High-Definition) DVD standard is an extension of the DVD standard, and the Blu-Ray (Blu-ray) standard optical disk is capable of recording many videos on a single disk at a high density in the same way as the HD DVD standard. Have already been put into practical use, and player devices and recorder devices are available.

  Note that HD DVD recorders also have a recording mode that provides high-quality video after recording (very little degradation due to recording), so dubbing (copying) or moving (moving) based on the type of video and audio signals. ) Is known to be limited. Also, there are recording media (recording media) that can be dubbed and moved, one that allows dubbing and moving only once, and one that cannot be dubbed and moved.

Japanese Patent Application Laid-Open No. 2004-228561 shows a list of types of optical discs that can be dubbed by a program when dubbing is performed.
JP 2006-216130 A

  In the display method of Patent Document 1, if the optical disc (recording medium) prepared by the user who is trying to dubb and the disc displayed as the dubbable optical disc do not match, the user understands why the prepared optical disc cannot be selected. It often raises questions about "I can't do it", which causes inconvenience to users (bad operability).

  An object of the present invention is to provide a video recording / reproducing apparatus capable of displaying dubbable content on a recording medium prepared by a user in response to a dubbing request from the user.

  The present invention has been made on the basis of the above problems, and a recording device capable of recording an arbitrary number of contents, and a content to be copied or moved to a recording medium on which the content recorded in the recording device can be copied or moved A disc drive unit for recording content, a control device for identifying content that can be copied or moved from the recording device to the recording medium according to the standard and type of the recording medium set in the disc drive unit, and set in the disc drive unit A display control device that generates an output screen signal so that only content that can be copied or moved from the recording device to the recording medium is displayed according to the standard and type of the recorded recording medium. A video recording / reproducing apparatus.

  By using one embodiment of the present invention, when a dubbing / move of content (program) is requested, whether or not a dubbing / movable recording medium (optical disc) is inserted or is currently inserted Since dubbing / move is prohibited for an optical disc, it is possible to easily notify the user of “why dubbing / move cannot be performed” such as the necessity of disc replacement. As a result, the “user cannot understand” question that dubbing / moving cannot be performed on the prepared optical disk is solved, and the inconvenience (bad operability) of the user is solved.

  That is, by using one embodiment of the present invention, it is possible to improve the understanding and operation of the user's device by displaying a list of recorded content dubbing guides instead of messages and alerts.

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

  FIG. 1 shows an example of an image recording / playback apparatus (also referred to as a video recording apparatus or a recorder apparatus) to which an embodiment of the present invention can be applied.

  The video recording apparatus 1 includes, for example, a satellite antenna 11 that receives a satellite digital TV broadcast provided via a broadcast satellite or a communication satellite, and a BS / CS tuner 13 that selects a predetermined channel from a broadcast wave received by the antenna 11. And a terrestrial tuner 17 that selects a predetermined channel from a broadcast wave received by the antenna 15 and a terrestrial wave antenna 15 that receives a terrestrial digital / analog TV broadcast provided by a ground wave (spatial wave). Needless to say, the video and audio signals may be supplied via an external input terminal (not shown).

  Broadcast waves acquired through the respective tuners, that is, television programs, are decoded by the main control block 19 and recorded by the recording device 21 in a predetermined recording (recording) mode. Note that the recording device 21 has developed a hard disk device (HDD) 23 provided with a recording capacity of, for example, several hundreds of Gbytes, a DVD disc that is, for example, an optical disc of the DVD standard, or the DVD standard, and has further increased the recording density. An HD (High-Definition) includes a disc drive unit 25 capable of recording information on an HD DVD disc of the DVD standard.

  Connected to the main control block 19 are a user operation input unit 27 to which operation information from the user is input and a remote control receiver 29 that receives input from the remote control terminal RM.

  Although not described in detail, the main control block 19 includes a video system ADC (analog-digital converter), an audio (sound / music) system ADC (analog-digital converter), an encoder, a decoder, and the like. If the audio signal is analog, it is converted into a digital signal and then encoded by the recording device 21 so that it can be digitally recorded. At the time of reproduction, the video signal and the audio signal read from the recording device 21 are decoded and supplied to the output terminal 31 described below.

  The main control block 19 includes an OSD (On Screen Display) (not shown). For example, the main control block 19 receives operation information input via the user input unit 27 or the remote control receiver 29, a selected channel, or a dubbing or moving instruction. Corresponding selection screens and operation screens are output so as to be displayed on a television receiver connected to the output terminal 31 or a monitor device although not described in detail. Needless to say, an audio output device (speaker, AV (Audio Video) amplifier) or the like is connected to the output terminal 31 (not shown).

  The output from the OSD (On Screen Display) of the main control block 19 is, for example, semi-transparent or superimposed on the playback output video with respect to the playback output video output from the recording device 21 by the mixer 33. By “α blending” that can display a predetermined ratio of the reproduction output video, the reproduction output video is also displayed and supplied to the output terminal 31.

  Next, an example of dubbing (duplicating) or moving (moving) a recorded title (program or content) in the video recording apparatus (information recording / reproducing apparatus) shown in FIG. 1 will be described.

  When a “view navigation” is selected from the user by the “setting” button 201 of the remote control terminal RM shown in FIG. 2, a “view navigation (function list)” screen 301 as shown in FIG. 3 is displayed. .

  In the various displays (screens) described below, the currently selected display is highlighted by four arrow keys in the up / down / left / right directions not described in detail on the remote control terminal RM, for example, confirmed by the “OK” key 211. As a result, the next screen (or display) is displayed, or processing corresponding to the input command is executed.

  Each “display” described below is a display example displayed on the screen of the television receiver (monitor device) M connected to the output terminal 31 in the video recording apparatus 1. Needless to say, this display pattern is generated by the OSD of the main control block 19 and is superimposed on the video output output from the recording device 21 via the mixer 33.

  When a “dubbing” display 311 is selected on the “viewing navigation (function list)” screen 301 shown in FIG. 3, an “editing navigation (dubbing)” screen 401 is displayed as shown in FIG.

  The “editing navigation (dubbing)” screen 401 shown in FIG. 4 includes a supplier information display area 410 for displaying data supplier information, a dubbing destination information display area 420 for displaying dubbing destination information, a display screen, A control button area 430 in which control buttons used for inputting the operation mode are displayed.

  In the supplier information display area 410, for example, ten thumbnail screens (with screen number display) and information on programs that are focused (cursor) among programs (contents) displayed on the thumbnail screens are displayed. A content information display field 411 is displayed. In the example shown in FIG. 4, among the ten thumbnail screens, the programs (contents) having the same screen numbers [008] and [009] will be described below, but the recording medium in the dubbing destination information display area 420 is described below. Based on the type of recording medium displayed in the display area 421, a gray-down display (colorless / monochrome / transparent) is displayed in order to make it easy for the user to understand that neither dubbing nor moving is possible. Display with a reduced rate) or shaded display.

  In the dubbing destination information display area 420, information on the recording medium, that is, the optical disk currently loaded in the disk drive unit 25 of the recording device 21, that is, the standard (format) and type (rewritable -RAM / RW type, one time recording) Recording medium display area 421 in which “-R type” is displayed, and programs (contents) that are permitted to be dubbed or moved to the recording medium currently loaded in the disk drive unit 25 of the recording device 21 are displayed. A dubbable content display area 422 and a help (HELP) display field 423 for displaying the reason when there is content that cannot be dubbed are displayed.

  FIG. 5 is the same screen as the “editing navigation (dubbing)” screen 401 already described with reference to FIG. 4, but the optical disk loaded in the disk drive unit 25 of the recording device 21 is CPRM compatible -R (1 This shows a case where the recording can be performed only once and the copy is a one-time copy by CPRM (Content Protection for Recordable Media).

  That is, in the display (screen) of FIG. 5 and the display (screen) of FIG. 4, all 10 thumbnail screens (with screen number display) displayed in the supplier information display area 410 can be dubbed / moved. In addition, [CPRM-R] is displayed as the type of the currently loaded optical disk in the recording medium display area 421 of the dubbing destination information display area 420, and the title (program) displayed in the dubbable content display area 422 is displayed. The increase is different. In FIG. 5, a help (HELP) display field 423 displays “Move is only possible / contents in the HDD will be deleted after the move is completed”.

  As described above, in FIG. 4, it is displayed in the recording medium display area 421 that the inserted medium is “DVD-RAM”, and also in the supplier information display area 410, the gray-down display (color removal / Monochrome display indicates that some contents (programs) cannot be moved / dubbed. Further, only the content (program) for which move / dubbing is permitted is displayed in the dubbable content display area 422.

  On the other hand, in FIG. 5, it is displayed in the recording medium display area 421 that the inserted medium is “-R for CPRM”, and the move / dubbing is also performed in the supplier information display area 410. What cannot be done (all possible in FIG. 5) is displayed. Further, the number of contents (programs) displayed in the move / dubbable content display area 422 is increased as content (programs) permitted to be moved / dubbed as compared to the example shown in FIG.

  In the help (HELP) display field 423 of the dubbing destination information display area 420, in the case of the example of FIG. 4, for example, “a disc that is not permitted to be dubbed / moved is loaded” / “disc is“ CPRM ” A message explaining “why can't dubbing / move” is displayed, such as “Replace with a compatible -R disc”.

  Needless to say, the title (content name) currently focused (cursor) is also displayed in the title display area 424 of the dubbing destination information display area 420. In the vicinity of the HELP column 423 (above the “HELP column” in the display examples of FIGS. 4 and 5), a media information column 425 for displaying the type of the disc is also prepared, and the display of the recording medium display area 421 is displayed. In addition, it is easy to identify the user as character information.

  On the other hand, in the content information display field 411 of the supplier information display area 410, the content to be dubbed is not permitted to be dubbed (copying to an optical disc is not possible with the content left in the HDD) or only the move is performed. A message to the user is displayed indicating that it is possible (when content is copied to the optical disc, the content in the HDD is deleted).

  Needless to say, whether the content can be copied or moved is determined for each chapter when the content includes an arbitrary number of chapters (arbitrary breaks within one content).

  Various known methods can be used for acquiring / identifying information on contents (programs) recorded in the HDD 23 and information on optical disks loaded in the disk drive unit 25. For example, the disc format information is confirmed from the UDF information of the optical disc, the title information is acquired from the VOB and SOB of the IFO information, the title attribute is identified, and the dubbing / moveability can be determined from the two pieces of information. As contents, it is possible to identify CPRM support or prohibition of movement and dubbing based on information such as TS (Transport stream) / PS (Packetized stream), presence / absence of compression, digital or analog.

  6 is a display example in which the inserted medium (optical disc) and dubbing / moveability are associated with each other in the video recording apparatus shown in FIG. 1 (actual display is the display shown in FIGS. 4 and 5). It is the schematic explaining an example of (displayed in the content information display column 411 of the supplier information display area 410 of a screen).

  For example, in the display examples shown in FIGS. 4 and 5, the content information display field 411 of the supplier information display area 410 is used when the type of the selected content and the content can be dubbed / moved. Displays the type (format) of media that can be used.

  In the case of the dubbing function, information such as the copy mode and type that can be selected based on the selected content and the attribute of the disc inserted in the disc drive unit 25, that is, only the move is possible, is also displayed.

  FIG. 8 is a flowchart in a case where dubbing (duplicating) or moving (moving) a recorded title (program or content) described with reference to FIGS. 4 and 5 is realized as software.

  First, when the remote control terminal RM instructs to start the editing mode, an “editing navigation (dubbing)” screen is displayed. That is, a range of recorded titles (programs or contents) to be displayed in the supplier information display area 410 is specified and sequentially displayed on a predetermined number of thumbnail screens (with screen number display). For example, the title with the latest recording date and time is assigned to the thumbnail display area [010], and nine titles are displayed in all thumbnail display areas [009] to [001] so that the date and time goes back (8-1). ).

  At this time, for each title, for example, it is determined whether or not CPRM is allowed to be moved (8-2), and for the thumbnail screen of the title that is allowed to move to the CPRM compatible disc, for example, gray-down display is performed. It is displayed by (color removal / monochrome display) (8-3).

  Subsequently, an alert message such as “Please insert a CPRM compatible disk” is displayed on the connected monitoring device M by the OSD included in the main control block 19 (8-4).

  Thereafter, it is checked whether or not the optical disk D set in the disk drive unit 25 has been replaced (8-5). If the optical disk D is replaced (8-5-YES), then it is a CPRM compatible disk. Is checked (8-6).

  When it is checked that the set disc is a CPRM compatible disc (8-6 YES), the title displayed in gray down in (8-3) is changed to normal display (8-7). At this time, the display of the recording medium display area is changed from the display of the optical disc so far to the [CPRM] display as shown in FIG. 5 (8-8).

  Also, a thumbnail image of the title that was gray-down displayed in (8-3) (the title changed to normal display in (8-7)) is added to the dubbable content display area (8-9).

  The flow shown in FIG. 8 may be changed based on the type of the optical disk set in the disk drive unit, as shown in FIG.

  When the editing mode is instructed (input) by the remote control terminal RM, an “editing navigation (dubbing)” screen is displayed (9-1).

  Subsequently, it is checked whether or not the optical disk set in the disk drive unit 25 is a CPRM compatible disk (9-2). When a disk different from the CPRM compatible disk is set (9-2-NO) Then, a message such as “Please set CPRM compatible disk” is displayed on the monitor device in OSD (9-3).

  Thereafter, it is checked whether or not the optical disk D set in the disk drive unit 25 has been replaced (9-4). If the optical disk D is replaced (9-4-YES), is it again a CPRM compatible disk? A check is made (9-2).

  When it is checked that the set disc is a CPRM compatible disc (9-2-YES), the display of the recording media display area is changed from the display of the optical disc set so far as shown in FIG. , [CPRM] display is changed (9-5). A predetermined number of thumbnail screens (with screen number display) are sequentially displayed in the supplier information display area. For example, the title with the latest recording date and time is assigned to the thumbnail display area [010], and nine titles are displayed in all thumbnail display areas [009] to [001] so that the date and time can be traced back (9-6). ).

  In the dubbable content display area, among the thumbnail images displayed in (9-6), titles that are allowed to be moved to the CPRM disc are sequentially displayed (9-7).

  As described above, by using one of the embodiments of the present invention, when a dubbing / move of content (program) is requested, is a recording medium (optical disc) that can be dubbed / moved inserted? It is possible to easily notify the user of “why dubbing / move cannot be performed” such as no or dubbing / move is prohibited in the currently inserted optical disk, and the disk needs to be replaced. As a result, the “user cannot understand” question that dubbing / moving cannot be performed on the prepared optical disk is solved, and the inconvenience (bad operability) of the user is solved.

  Accordingly, by displaying a list of recorded content dubbing guides as well as messages and alerts, the user's understanding and operation of the device can be improved.

  That is, in the part selection list display (editing navigation) screen of the video recording apparatus, for the function to be dubbed, content that can be dubbed based on the inserted media is displayed, for example, the inserted media is a DVD-R. In addition, the operability and convenience of the user are improved by displaying the identification based on the environmental information such as whether the video format or the high-speed dubbing mode or the UDF information of the recorded content.

  It should be noted that the content of the present invention is not limited to the form described here, and it goes without saying that various other forms can be taken without departing from the spirit of the invention. In addition, the embodiments may be implemented by appropriately combining them as much as possible, or by deleting a part thereof, and in that case, various effects resulting from the combination or deletion can be obtained.
