[0003]
  As an example of this optical disc, there is a DVD (Digital Video Disc, Digital Versatile Disc) disc on which a bit stream composed of a compressed video signal and audio signal is recorded. There is a DVD player as an optical disk reproducing apparatus that reads information recorded on the DVD disk, decodes it into a video signal and an audio signal, and reproduces it.
[0004]
  Playback of a DVD disc by a DVD player is performed as follows.
[0005]
  The DVD disc records information such as compressed video signals and audio signals, as well as header information indicating the recording positions of these pieces of information on the DVD disc.
[0006]
  This header information includes position information, time interval information, and the number of position information. The position information indicates a recording position (address) on the disc at which video information and image information are recorded for each time interval specified by the time interval information. Further, the number of position information indicates the number of position information included in the header information.
[0007]
  When the DVD player performs reproduction, the header information is first read from the DVD disc, and then the compressed video information and image information are read by accessing a desired address using the header information. Then, the video information and the image information are decoded and reproduced on the display screen.
[0008]
  For such a DVD player, in order to easily search for a desired video scene at the time of reproduction, for example, Japanese Patent Laid-Open No. 2001-45423 discloses the following technique.

  In the above configuration, when an optical disc is inserted from the optical disc insertion slot 5, the optical disc playback device 1 loads the optical disc into the optical disc playback device 1 by autoloading. Then, the reproduction operation selected by the operation selection switch 6 is performed. Details of this reproduction operation will be described later.
[0128]
  Thereafter, when the optical disc eject button 4 is pressed, the optical disc reproducing apparatus 1 ejects the optical disc.
[0129]

  Here, the optical disk D is a reproducible recording medium such as a DVD-ROM. The optical disc D may be an optical disc having a diameter of 8 cm, or may be an optical disc having an arbitrary diameter such as a diameter of 12 cm or 6 cm.
[0133]
  The optical pickup 11 is for irradiating a laser beam (not shown) to the optical disc D and reading video information recorded on the optical disc D as digitally modulated pit information.
[0134]
  The optical disk control circuit 12 is a circuit that performs processing for controlling tracking, focusing, movement in the radial direction (optical disk radial direction), laser light irradiation, and the like of the optical pickup 11.
[0135]
  The signal processing circuit 13 is a circuit that performs processing for equalizing the waveform of the pit information read by the optical pickup 11 and outputting it to the system internal bus 15 as an MPEG-2 video stream.
[0136]
  The nonvolatile memory 14 is for storing index information. The nonvolatile memory 14 is, for example, a semiconductor memory such as a flash memory, a magnetic memory such as an MRAM, or a ferroelectric memory such as FeRAM. Alternatively, the nonvolatile memory 14 may be a hard disk. Information stored in the non-volatile memory 14 is retained even when the optical disc playback apparatus 1 is powered off.
[0137]
  The system internal bus 15 is a signal line used for data transfer in the optical disc playback apparatus 1.
[0138]
  The first buffer RAM 16 is for buffering read information. By buffering the read information in the first buffer RAM 16, even if there is a temporary failure in reading the optical disc D, for example, the reproduction operation can be continued without any influence of the failure.
[0139]
  The system control microcomputer 17 is for controlling data transfer via the system internal bus 15.
[0140]
  The second buffer RAM 18 is a so-called video memory for use as a buffer when decoding the compressed video signal and audio signal. The second buffer RAM 18 is made of SDRAM, for example.
[0141]
  The video information modulation / demodulation unit 19 is for decoding the compressed video signal and audio signal using the second buffer RAM 18 as a buffer.
[0142]
  The operation key 20 is used to input instructions such as playback, stop, and search to the optical disc playback apparatus 1. The operation keys 20 collectively indicate the power switch 2, the discharge button 4, the operation selection switch 6, the image selection switch 7, the image determination switch 8, the cancel switch 9, and the image quality control switch 10 shown in FIG.
[0143]
  The interface microcomputer 21 transmits data input from the operation keys 20 to the system control microcomputer 17.
[0144]
  The video information processing unit 22 is for converting a digital video information signal into an NTSC signal.
[0145]
  The display generation unit 23 is for transmitting signals from the interface microcomputer 21 and the video information processing unit 22 to the display control unit 24.
[0146]
  The display control unit 24 is for controlling the display panel P to display an image.
[0147]
  The USB control unit 25 is for transmitting, for example, a video signal and an audio signal to a personal computer (not shown) connected to the outside.
[0148]
  The optical disc playback apparatus 1 according to the present embodiment not only accesses the nonvolatile memory 14, but also via the USB control unit 25, for example, an external hard disk drive (not shown) or the like outside the optical disc playback apparatus 1. The non-illustrated nonvolatile memory may be accessed.
[0149]
  The interface unit 26 is an interface for performing communication with an operation remote controller (operation remote controller) (not shown).
[0150]
  Note that the display panel P of the present embodiment is a display panel provided outside the optical disc playback apparatus 1. The display panel P may be integrated with the optical disc reproducing apparatus 1, for example.
[0151]
  The operation display unit 3 is the same as the operation display unit 3 shown in FIG. Also, the configuration relating to autoloading and ejection of the optical disc is not shown.
[0152]
  Each block shown in the block diagram of FIG. 1 is not limited to a configuration realized as a separate member, but may be a functional block realized by executing a program, for example.
[0153]
  In the above configuration, the optical disc playback apparatus 1 performs a playback operation as follows.
[0154]
  First, pit information is read from the optical disc D in a digitally modulated state using the optical pickup 11 controlled by the optical disc control circuit 12.
[0155]
  The signal processing circuit 13 equalizes the waveform of the pit information and then outputs it to the system internal bus 15 as an MPEG-2 video stream. At this time, the MPEG-2 video stream is also temporarily stored in the first buffer RAM 16.
[0156]
  Then, transfer control of data (MPEG-2 video stream) output to the system internal bus 15 is performed by the system control microcomputer 17. This data is decoded by the video information modulation / demodulation unit 19 using the second buffer RAM 18 as a video memory. The digital video information signal composed of the decoded 16-bit parallel data is sent to the video information processing unit 22.
[0157]
  The video information processing unit 22 converts this digital video information signal into an NTSC signal. The NTSC signal is transmitted to the display panel P via the display generator 23 and the display controller 24. On the display panel P, the NTSC signal is displayed as a reproduced image and reproduced.
[0158]
  Note that the audio signal is also reproduced in the same manner. That is, in the same manner as the video data, an MPEG audio stream read from the optical disc D is decoded as an audio signal and output from a speaker (not shown).
[0159]
  Further, the above video signal and audio signal can also be transmitted to an external personal computer via the USB control unit 25.
[0160]
  In the above description, the case of reproducing video information (moving image) recorded in the MPEG-2 format has been described. However, the present invention is not limited to this.
[0161]
  For example, a still image using an I picture in MPEG format or a JPEG image can be similarly displayed on the display panel P via the video information modulation / demodulation unit 19. The JPEG encoding (compression) operation is almost the same as the MPEG I picture encoding operation. Therefore, in the video information modulation / demodulation unit 19, JPEG format decoding (decoding) operation is also possible by switching part of the circuit operation.
[0162]
  Next, an operation remote controller (remote control device) that controls the reproduction of the optical disk reproducing device 1 will be described.
[0163]
  The operation remote controller includes a member that functions in the same manner as the optical disc playback apparatus 1 in order to operate the optical disc playback apparatus 1. That is, as shown in FIG. 3, the operation remote controller 31 includes a power switch 32 similar to the power switch 2, an operation display unit 33 similar to the operation display unit 3, an operation selection switch 34 similar to the operation selection switch 6, and an image selection. An image selection switch 35 similar to the switch 7, an image determination switch 36 similar to the image determination switch 8, and a cancel switch 37 similar to the cancel switch 9 are provided.
[0164]
  The configuration of the operation remote controller 31 will be described in more detail based on FIG. 4 as follows.
[0165]
  The operation remote controller 31 has a configuration similar to that of the optical disc playback apparatus 1 in order to operate the optical disc playback apparatus 1. That is, as shown in FIG. 4, a system internal bus 38, a system control microcomputer (display control means, storage control means, reproduction control means) 39, operation keys 40, an interface microcomputer 41, and an interface unit 42 are provided.
[0166]
  Each member performs substantially the same function as a member having the same name included in the optical disc playback apparatus 1.
[0167]
  That is, the operation key 40 is used to input an instruction for reproduction, stop, search, and the like to the optical disc reproduction apparatus 1. The operation keys 40 collectively indicate the power switch 32, the operation selection switch 34, the image selection switch 35, the image determination switch 36, and the cancel switch 37 shown in FIG.
[0168]
  An input from the operation key 40 is transmitted to the interface unit 26 of the optical disc reproducing apparatus 1 via the interface microcomputer 41 and the interface unit 42. Thereby, control such as reproduction in the optical disc reproduction apparatus 1 can be performed.
[0169]
  Also, the operation state of the optical disc playback apparatus 1 is received on the interface unit 42 by the information transmitted from the optical disc playback apparatus 1 and displayed on the operation display unit 33.
[0170]
  Information transmitted from the optical disc playback apparatus 1 is transmitted to the system control microcomputer 39 via the interface unit 42 and the interface microcomputer 41. This information can also be output to an external device via the system internal bus 38 and the USB control unit 43, for example.
[0171]
  Next, storage of index information in the optical disc playback apparatus 1 will be described.
[0172]
  The index information in this embodiment includes title information, a guide image, and a scene image.
[0173]
  Here, the title information is information indicating the title of the content recorded on the optical disc D. This title information is a character string input using the operation keys 20 and 40, for example. Also, the title information may be read from the optical disc D.
[0174]
  The guide image is a still image of an arbitrary scene in the video information recorded on the optical disc D. This guide image can be selected using the operation keys 20 and 40 when the optical disc D is reproduced.
[0175]
  For example, during playback of the optical disc D, an image displayed on the display panel P can be selected by selection using the image determination switches 8 and 36 as the operation keys 20. The selected image is converted by the video information modulation / demodulation unit 19 into, for example, a still image in JPEG format. The converted still image is stored in the nonvolatile memory 14 as one file via the system internal bus 15.
[0176]
  This guide image is recorded in the non-volatile memory 14 as a thumbnail image. A thumbnail image means a reduced display of an image when data such as an image file is opened. This thumbnail image is used to display a plurality of images as a list. Note that the size of the guide image according to the embodiment is not limited to this. However, if the thumbnail images are recorded, the capacity to be recorded in the nonvolatile memory 14 can be reduced.
[0177]
  In the present embodiment, the title information and the guide image are recorded in the nonvolatile memory 14 as one set as index information indicating the contents recorded on one optical disc D.
[0178]
  A set of title information and guide images that are recorded in this manner and collected for a plurality of optical disks is hereinafter referred to as a title list. With reference to this title list, video information recorded on the optical disc can be efficiently searched as will be described later.
[0179]
  Since the title list as index information is all stored in the nonvolatile memory 14, even if the power switch 2 or 32 of the optical disc playback apparatus 1 is turned off and the power is turned off, the title list is stored semipermanently.
[0180]
  The scene image is a still image of a plurality of scenes in the video information recorded on the optical disc D. By using this scene image, for example, it is possible to easily search for a specific scene recorded on one optical disc D.
[0181]
  The scene image may be configured to be selected using the operation keys 20 and 40 as described above during reproduction of the optical disc D, for example, or a system control microcomputer as a display control unit at predetermined time intervals, for example. A configuration may be adopted in which selection is made by 17 controls. The selected scene image is stored in the nonvolatile memory 14. The recording position (address) on the optical disc D corresponding to the scene image as auxiliary information is also stored in the nonvolatile memory 14.
[0182]
  In addition to the still image as the scene image, the elapsed time from the start of reproduction of the optical disc D can be stored in the nonvolatile memory 14 as auxiliary information.
[0183]
  The scene image and the corresponding recording position on the optical disc D recorded in the nonvolatile memory 14 in this way are hereinafter referred to as a scene list.
[0184]
  In the above-described audio data reproduction, a part of the reproduced audio data can be attached to the still image file and stored in the nonvolatile memory 14. As a result, a still image file with audio data can be stored in the nonvolatile memory 14.
[0185]
  Next, a search with reference to index information in the optical disc playback apparatus 1 will be described.
[0186]
  The index information may be stored as described above, but is not limited thereto. For example, it may be downloaded via the Internet and stored in the nonvolatile memory 14 as nonvolatile storage means.
[0187]
  The optical disk reproducing apparatus 1 according to the present embodiment performs the search using the index information, as part of the operation keys 20 and 40, the image selection switches 7 and 35, the image determination switches 8 and 36, and the cancel switches 9 and 37. It has.
[0188]
  The image selection switches 7 and 35 are switches for selecting a specific target image from the images displayed on the display panel P. The image determination switches 8 and 36 are switches for determining a selected image. Cancel switches 9 and 37 are switches for canceling selection of a selected image.
[0189]
  In the optical disc playback apparatus 1 of the present embodiment, a pointer is displayed on the display panel P, and the movement of the pointer by the operation keys 20 and 40 is linked with the display generating unit 23 to select an image displayed on the display panel P. It can be carried out. In other words, the pointer displayed on the display panel P by the display generation unit 23 can be moved using the operation keys 20 and 40 to select, determine, and cancel the image displayed on the display panel P.
[0190]
  In the above configuration, when input is made by the operation keys 20 and 40, the input data is transmitted to the interface microcomputer 21. Then, the operation is executed via the system control microcomputer 17.
[0191]
  The details of this operation will be described below with reference to FIGS.
[0192]
  First, when the optical disc D is not loaded, for example, when the image determination switches 8 and 36 of the operation keys 20 and 40 are pressed, a title list display instruction is issued.
[0193]
  As shown in FIG. 5, on the display screen P1 of the display panel P, the information of the above-described title list read from the nonvolatile memory 14 is displayed together with the selection pointer X as a plurality of thumbnail images T1 to T12 and the like. The For example, the title list is a collection of title information and guide images that are selected at the time of reproduction of a plurality of optical disks D that have been reproduced so far.
[0194]
  FIG. 5 shows thumbnail images T1 to T12 as guide images in the title list, but title information is not shown for simplicity.
[0195]
  Here, since the title list as index information is all stored in the nonvolatile memory 14, the power switch 2 and 32 of the optical disc playback apparatus 1 are turned off to turn off the power, and then the power is turned on again. Even in such a case, it is possible to read from the nonvolatile memory 14 and perform a search efficiently.
[0196]
  In addition, as described above, the title information that is character information and the thumbnail images T1 to T12 that are guide images that are still images are displayed together as the title list, thereby making it possible to search for video information more visually and in a visual manner. The search can be performed accurately.
[0197]
  Next, the selection pointer X is moved using, for example, the image selection switches 7 and 35. By this movement, the selection pointer X is moved onto a specific thumbnail image. As described above, this can be performed while viewing thumbnail images T1 to T12 as a title list.
[0198]
  Then, for example, a specific image is selected using the image determination switches 8 and 36. As a result, the optical disc D corresponding to the selected thumbnail image can be loaded. That is, for example, when the optical disc reproducing apparatus 1 can include a plurality of optical discs D, the corresponding optical disc D can be selected and the selected optical disc D can be reproduced. For example, when the corresponding optical disc D is not provided, the fact is displayed, and the optical disc D can be reproduced as soon as the corresponding optical disc D is provided. Thus, the operability of the optical disc playback apparatus 1 can be improved by adopting the automatic start system.
[0199]
  In addition, the above-described operation can be performed using the selection button 44. That is, in order to select a certain thumbnail image, the pointer X may be moved and selected directly as described above, or may be selected with the image selection switches 7 and 35, or the selection button 44 may be selected. It is also possible to move the pointer X and select it.
[0200]
  The scroll bar 45 indicates the current display position when the thumbnail image is displayed over a plurality of pages, and is used for moving between the plurality of pages. Normally, when the number of thumbnail images recorded as a title list increases, the display screen P1 cannot display all at once. For this reason, if the present display position is shown using the scroll bar 45, a search will become easy. If the scroll bar 45 is used to move between pages, the current display position can be selected while grasping, so that the search becomes easier.
[0201]
  Further, as described above, the optical disc playback apparatus 1 according to the present embodiment not only selects one thumbnail image set from the title list and selects and plays back the corresponding optical disc D, but also the optical disc D. It is also possible to search for a predetermined video scene in the video information recorded in.
[0202]
  For this purpose, on the title list screen shown in FIG. 5, for example, the thumbnail image T6 selected using the pointer X is selected again using the pointer X.
[0203]
  As a result, the above-mentioned scene image recorded in the nonvolatile memory 14 is read, and as shown in FIG. 6, a video scene selection screen (scene list) for searching for a predetermined video scene is displayed on the display screen P2. The
[0204]
  Here, the thumbnail image T6 displayed at the upper left of the display screen P2 is the same as the thumbnail image T6 shown in FIG.
[0205]
  The other thumbnail images Q1 to Q11 are scene images (scene list) stored in the nonvolatile memory 14 as described above.
[0206]
  With reference to these thumbnail images Q1 to Q11 and, for example, the elapsed time from the start of reproduction of the optical disc D recorded as described above, it is possible to easily search for a desired video scene.
[0207]
  Further, in the above configuration, by selecting one thumbnail image from the displayed thumbnail images Q1 to Q11, playback of the optical disc D may be started from a video scene corresponding to the selected thumbnail image. it can.
[0208]
  That is, on the display screen P2, for example, the thumbnail image Q5 is selected using the displayed pointer X. In this selection, for example, the selection button 44 may be used instead, or the scroll bar 45 may be used supplementarily. Other operation keys 20 and 40 may be used.
[0209]
  Next, the optical disc D is loaded with the thumbnail image Q5 selected as described above. As a result, the recording position of the optical disc D is accessed based on the auxiliary information stored in the nonvolatile memory 14 together with the thumbnail images Q1 to Q11 as scene images, and the optical disc D from the scene corresponding to the selected thumbnail image Q5. Is played.
[0210]
  That is, in the same manner as described above, for example, when the optical disc reproducing apparatus 1 can include a plurality of optical discs D, the corresponding optical disc D is selected, and the selected optical disc D is reproduced from the corresponding scene. it can. For example, when the corresponding optical disk D is not provided, this is displayed, and when the corresponding optical disk D is provided, the optical disk D can be reproduced from the scene. Thus, the operability of the optical disc playback apparatus 1 can be improved by adopting the automatic start system.
[0211]
  As described above, by storing the thumbnail images Q1 to Q11 as scene images in the nonvolatile memory 14, the search operation of the video information recorded on the optical disc D can be simplified. In addition, the operability of the optical disc playback apparatus 1 can be improved.
[0212]
  The search using the index information described above will be described with reference to the flowchart of FIG.
[0213]
  After the power is turned on, in step S1, the title list information is read from the nonvolatile memory 14 and displayed on the display panel P as a thumbnail image.
[0214]
  In step S2, it is detected that desired title information or a guide image is selected from information in the title list.
[0215]
  In step S3, it is determined whether to reproduce the optical disc D on which the video information corresponding to the title information or guide image selected in step S2 is recorded or to search for scene information in the video information. .
[0216]
  In step S4 when reproduction is selected in step S3, the optical disc D is loaded. In step S5, the loaded optical disc D is reproduced.
[0217]
  If scene selection is selected in step S3, the scene list is displayed on the display panel P as a thumbnail image in step S6. In step S7, selection of a still image corresponding to a desired video scene is detected. In step S8, the optical disc D selected in step S2 is loaded. In step S9, the optical disk D is reproduced from the scene selected in step S7.
[0218]
  As described above, the optical disc playback apparatus 1 according to the present embodiment includes the nonvolatile memory 14 that stores the index information and the system control microcomputer 17 that serves as a display control unit that displays the index information.
[0219]
  Therefore, the optical disc reproducing apparatus 1 accesses the nonvolatile memory 14 and displays the stored index information on the display panel P as display means, so that the video information recorded on the optical disc D can be easily searched. be able to.
[0220]
  [Embodiment 2]
  Another embodiment of the present invention will be described below with reference to FIGS.
[0221]
  As with the optical disc playback apparatus 1 described in the above embodiment, the optical disc playback apparatus according to this embodiment uses non-volatile index information for searching video information in order to easily search for video information. It is to be stored in the memory. When searching, the nonvolatile memory is accessed and the index information is referred to search.
[0222]
  Here, in the optical disk reproducing apparatus according to the present embodiment, the nonvolatile memory is detachable from the optical disk reproducing apparatus.
[0223]
  Thus, for example, even when the recording capacity of the nonvolatile memory is insufficient when newly recording index information, the new index information can be recorded in the nonvolatile memory by replacing the nonvolatile memory. it can. Further, it is not necessary to delete the index information recorded in the nonvolatile memory. Even when the desired index information is not recorded in the nonvolatile memory, new index information can be referred to by exchanging the nonvolatile memory.
[0224]
  Such a shortage of recording capacity of the non-volatile memory occurs, for example, in the optical disk reproducing apparatus according to the present invention by reproducing a new optical disk a plurality of times and storing the index information in the non-volatile memory accordingly. sell.
[0225]
  As shown in FIG. 8, an optical disc playback apparatus (video information playback apparatus) 51 according to this embodiment includes a power switch 2, an operation display unit 3, an optical disc ejection button 4, an optical disc insertion slot 5, an operation selection switch 6, and an image selection. A switch 7, an image determination switch 8, a cancel switch 9, an image quality control unit 10, a memory connection terminal 52, and a nonvolatile memory (nonvolatile storage means) 53 are provided.
[0226]
  Here, the same reference numerals are used for the same members as those described in the first embodiment. Description of these members is omitted.
[0227]
  The memory connection terminal 52 is a terminal for connecting the nonvolatile memory 53.
[0228]
  The nonvolatile memory 53 is for recording index information. The nonvolatile memory 53 is an external memory that can be attached to and detached from the optical disk playback device 53.
[0229]
  The nonvolatile memory 53 is, for example, a semiconductor memory such as an SD card (registered trademark) or a memory stick (registered trademark), a magnetic memory such as an MRAM, or a ferroelectric memory such as FeRAM. Further, the nonvolatile memory 53 as the nonvolatile storage means may be a removable hard disk.
[0230]
  Information recorded in the non-volatile memory 53 is retained even when the optical disk playback device 51 is turned off.
[0231]
  Further, the detailed configuration of the optical disc reproducing apparatus 51 is substantially the same as that shown in FIG. 1 in the above-described embodiment.
[0232]
  In this embodiment, in FIG. 1, the optical disk reproducing device referred to by reference numeral 1 is 51, and the nonvolatile memory referred to by reference numeral 14 is 53.
[0233]
  The reproduction operation of the optical disk D in this optical disk reproduction apparatus 51 is the same as that of the optical disk reproduction apparatus 1.
[0234]
  Also, the recording of index information in the optical disc reproducing apparatus 51 is substantially the same as that of the optical de-optical disc reproducing apparatus 1.
[0235]
  In the optical disk reproducing device 51, when storing the index information, if the capacity of the nonvolatile memory 53 is full, it can be replaced with a new nonvolatile memory 53.
[0236]
  Further, the operation of the system control microcomputer 17 as the display control means is changed along with the attachment / detachment of the nonvolatile memory 53.
[0237]
  In the above embodiment, for example, when the recording capacity of the nonvolatile memory 14 is insufficient, the system control microcomputer 17 deletes the old index information recorded in the nonvolatile memory 14. Record new index information.
[0238]
  On the other hand, in the present embodiment, when the storage capacity of the nonvolatile memory 53 is insufficient, the system control microcomputer 17 displays a display indicating that the storage capacity is insufficient on the display panel P or the operation display unit 3. -Display on 33 and prompt for replacement. As a result, it can be stored in the new nonvolatile memory 53.
[0239]
  Next, a search with reference to the index information stored as described above in the optical disc playback apparatus 51 will be described with reference to FIG.
[0240]
  In the following, the same operations as those described with reference to FIG. 7 in the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.
[0241]
  After the power is turned on, the non-volatile memory 53 is connected to the optical disk playback device 51 in step S10.
[0242]
  In step S11, the title list information is read from the nonvolatile memory 53 and displayed as a thumbnail image on the display panel P.
[0243]
  In step S12, it is determined whether or not desired title information or guide images exist in the title list.
[0244]
  If the desired title information or guide image exists in step S12, it is detected in step S13 that the desired title information or guide image is selected from the title list information. Thereafter, the process proceeds to step S3, and the optical disc D is reproduced as in the above-described embodiment.
[0245]
  If the desired title information or guide image does not exist in step S12, an instruction to replace the nonvolatile memory 53 is displayed on the display panel P in step S14. In step S10, a new nonvolatile memory 53 is connected.
[0246]
  Thus, if the nonvolatile memory 53 is detachable, the nonvolatile memory 53 can be detached and the search operation of the optical disk D can be simplified. In addition, the operability of the optical disc playback apparatus 51 can be improved.
[0247]
  Next, an operation remote controller (operation remote controller) (remote control device) 54 that controls the reproduction of the optical disk reproducing device 51 of the present embodiment will be described with reference to FIG.
