Description

  The present invention relates to a disk device such as a DVD player for recording / reproducing information on a DVD (Digital Versatile Disc), and in particular, a user records video / audio information (AV information) on a DVD or reproduces the recorded information. The present invention relates to a disk device that can discriminate the position by voice.

  Various AV devices have been proposed that allow the user to easily determine the operation content. As an example, there is known an information recording / reproducing system that enables dubbing while continuing normal operation (see, for example, Patent Document 1).

  This device comprises a first recording / reproducing device (high-speed device such as a hard disk device), a second recording / reproducing device (low-speed device such as a DVD-RAM) comparator and a remaining time display device.

  When the AV information is dubbed from the first recording / reproducing device to the DVD-RAM or the like of the second recording / reproducing device, the comparator compares the transfer rates of the two devices, and the AV information is matched to the slower transfer rate. Dubbing by controlling the transfer rate.

At this time, the remaining time until the end of dubbing is calculated from the slower transfer rate obtained from the comparator and the remaining amount of the desired AV information to be dubbed, and the remaining time until the end of the dubbing is displayed on the remaining time display device. It is supposed to do.
JP, 2000-175150, A An information signal recording and reproducing device for the purpose of notifying the minimum value or the predicted value of the remaining recording time prior to recording has been proposed (for example, see Patent Document 2).

  The recording / reproducing apparatus includes a unit for limiting the maximum value of the information amount per unit time of the output video signal of the information compression unit to a predetermined value, and a unit for detecting a recordable remaining storable capacity of the storage unit. , Means for calculating the remaining storage time from a predetermined maximum amount of information per unit time and the remaining recordable storage capacity of the storage means, and means for displaying the remaining recording time. .

  As a result, even in a video signal recording / reproducing apparatus in which the amount of information per unit time is not constant, it is possible to know the minimum value of the remaining time that can be stored in the storage means or the predicted value of the remaining time before recording.

Therefore, it can be determined in advance whether or not video data to be recorded can be recorded in the storage means, and usability can be improved.
JP, 2000-342241, A The cassette tape recorder which emits an oscillating sound at the time of operation is also proposed (for example, refer to patent documents 3).

  This cassette tape recorder is provided with an address signal recording means, an address signal search means, an address key, and a speed control means for quickly feeding the tape during the search and setting the tape feed speed to the reproduction speed after the search.

  When a plurality of address key buttons are operated, different oscillating sounds are generated.

Thus, when the button is operated, the type of the address key can be known from the oscillation sound.
Japanese Utility Model Publication No. 58-7289

  However, the information recording / reproducing system of Patent Document 1 can display the remaining time until dubbing is completed when dubbing AV information on a DVD-RAM or the like, but it does not inform the current dubbing position or the like by voice. There wasn't.

  Therefore, if the user does not go to see the display device for the remaining time, he cannot know how far he has progressed, and when he is doing something he needs to leave the place. Had to be interrupted.

  The recording / reproducing apparatus of Patent Document 2 can notify the minimum value of the remaining time that can be stored or the estimated value of the remaining time prior to recording when recording the video data in the storage means. The current recording position or the like was not notified by voice during recording.

  Therefore, the user cannot grasp how much the recording of the video data has progressed and there is an inconvenience that the user cannot know the remaining time.

  Further, the information recording / reproducing system of Patent Document 1 and the recording / reproducing apparatus of 2 are inconvenient for the visually impaired because the contents cannot be understood unless the display is viewed.

  Furthermore, since the cassette tape recorder of Patent Document 3 notifies the type of the address key by an oscillating sound when the button is operated, it is convenient for a blind person. However, the oscillating sound notifies the type of the address key. It has become only.

  For this reason, when AV information is recorded on an optical disk such as a magnetic tape or a DVD, or when this recorded information is reproduced, it is impossible to know the current position by voice, which is also inconvenient for visually impaired people. It remained.

  The present invention has been made in view of the above problems, and when recording AV information on a disc-type information storage medium or reproducing the recorded information, the user is informed of the recording / reproducing position and the occurrence of an error by sound. An object of the present invention is to provide a disc device that can handle the above.

  Hereinafter, embodiments of the disk device of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing an electrical configuration of a disk device according to an embodiment of the present invention.

  The disk device according to the present embodiment is applied to a DVD recorder, and is configured to reproduce information recorded on the DVD 1 by pressing a remote controller (remote controller) 22 and to record information of external input on the DVD 1. ing. In this example, description will be made mainly on the playback function.

  The DVD 1 includes a lead-in area, a user data area, and a lead-out area, and video / audio information (AV information) such as a movie program is recorded in the user data area.

  In such a DVD 1, when AV information is written as digital data in a user data area, an address for indicating a fine point (position) in a spiral recording track is assigned in advance. This address corresponds to the elapsed time from the first recording position to the last recording position of the AV information.

  In the TOC area of the lead-in area, the recording position of each chapter and each title is recorded with address data corresponding to the elapsed time information from the recording start position (first chapter of title number 1).

  Thus, when the data in the TOC area is read, the title number and chapter number of the movie, etc. recorded in the user data area of the recording track, the recording start and end positions, and the detailed recording time are displayed on the monitor 23. It can be displayed on the screen 23a.

In the lead-out area, data indicating the end of recording of AV information is written.
In FIG. 1, reference numeral 2 denotes a disk tray on which a DVD 1 is placed, and is rotated by a disk motor 3. An optical pickup 4 outputs reproduction information optically read from a track of the DVD 1 to the RF amplifier 5.

  The RF amplifier 5 sends reproduction information to a DSP (Digital Signal Processor) 6 and a servo control unit 7 which are signal processing units. The output of the servo control unit 7 is guided to the DSP 6.

  These RF amplifier 5, DSP 6, servo control unit 7, and the like are controlled by a microcomputer (hereinafter referred to as a front-end microcomputer) 9 that reproduces information from the DVD 1.

  The DSP 6 is connected to a track buffer RAM 8, and temporarily stores data amplified by the RF amplifier 5 and decoded in accordance with the DVD standard (here, compressed by MPEG: Motion Picture Expert Group). It has become.

  The DSP 6 is connected to a video encoder 13 and a D / A converter 14 via an A / V (Audio / Video) decoder 12.

  By the way, when the DSP 6 stores data from the DVD 1 in the track buffer RAM 8, if an error occurs, the DSP 6 generates an error code composed of predetermined numerical data and sends it to the front end microcomputer 9.

  This error occurs, for example, when the recording surface of the DVD 1 is scratched and cannot be read during reproduction and data cannot be stored in the track buffer RAM 8.

Note that a DVD recorder having a function of recording information on the DVD 1 similarly generates and outputs an error code.
An error at the time of recording occurs when a data stream input as write information to the DVD 1 cannot be sent to the optical pickup 4 side.

  The servo control unit 7 performs focusing servo and tracking servo control for the optical pickup 4 in accordance with commands and control data transmitted and received from the front-end microcomputer 9 via the DSP 6.

  Further, the configuration is such that the sled motor 10 that moves the optical pickup 4 in the radial direction of the DVD 1 and the tray motor 11 that drives the disc tray 2 are controlled.

  The A / V decoder 12 is connected to a microcomputer (hereinafter referred to as a back-end microcomputer) 16 that performs operation control for outputting various information reproduced from the DVD 1.

  The A / V decoder 12 expands the compressed data by MPEG read from the track buffer RAM 8.

  The A / V decoder 12 is connected to the A / V decoder RAM 15 and stores several screens of the digital data expanded as described above.

  The video encoder 13 encodes the video data from the A / V decoder 12 and sends it to the monitor 23 side shown in FIG. 2 via the output terminal 13a.

  Further, the D / A converter 14 converts the audio data from the A / V decoder 12 into an analog signal and sends it to the speaker side (not shown) via the output terminal 14a.

  Reference numeral 16 denotes a back-end microcomputer 16 having a work RAM 17 for storing setting data, sound effect data, and the like.

  This sound effect is an electronic sound, and digital data for sounding four types of “pi”, “pipi”, “pipipi”, and “pi” is stored corresponding to the code. The digital data “Pi” corresponds to the lead-in area code, “Pi-Pi” corresponds to the user data area, “Pi-Pi” corresponds to the lead-out area, and “Pi” corresponds to the error.

  The work RAM 17 also stores sound type data of sound effects corresponding to the addresses assigned to the tracks of the user data area.

  In this example, there are four kinds of sound effects, A, B, C, and D. However, more sound colors can be stored and set.

A front panel controller 18 is connected to the back end microcomputer 16. The front panel controller 18 controls the front panel 19 composed of an LCD or the like. The output of the key input unit 20 and the output of the receiving unit 21 that receives an infrared transmission signal from the remote controller 22 are guided.
The remote controller 22 includes various operation keys having the same functions as those of a popular DVD recorder, and a dedicated key for determining whether or not to sound a sound effect. This dedicated key may be a key that is not normally used.
As operation keys, a power key for turning on / off the power, an opening / closing key for opening / closing the tray, a numeric keypad, a menu key, a setting determination key, and the like are provided. Various function keys such as play, stop, fast forward and fast reverse keys are also provided. This function key also serves as a cursor key for selecting a menu item displayed on the screen 23a of the monitor 23.

  The menu key outputs a command for displaying a menu item on the screen 23a of the monitor 23 shown in FIG. The enter key outputs a command for determining the menu item selected according to the operation of the cursor key.

  In the remote controller 22 configured as described above, when any key is pressed, information corresponding to the operation content is transmitted to the DVD player 1 side as an infrared signal.

  By the way, the back-end microcomputer 16 is bidirectionally connected to the front-end microcomputer 9 and is configured to control the operation of the entire disk device by both 9 and 16.

  That is, when a command signal is input from the key input unit 20 or the remote controller 22, the servo control unit 7 is controlled in accordance with the content of the command, and information is recorded in the lead-in area, user data area, and lead-out area of the DVD 1 or the information. Control playback.

  Further, when recording information on the DVD 1 or reproducing the information, audio data corresponding to the area is read from the work RAM 17 and sent to the D / A converter 14 to produce a sound effect from the speaker.

  Further, when an error detection signal is input during recording / reproduction, the audio data in error is read from the work RAM 17 and sent to the D / A converter 14 to control the sound effect from the speaker.

  Note that it is stated in the instruction manual that a sound effect sound can be generated for a user who uses this DVD recorder during recording and playback.

  Next, the operation of the DVD recorder will be described with reference to the drawings.

  First, when a user records a television broadcast program or the like, the DVD 1 is set on the tray of the DVD recorder.

  In order to sound a sound effect during this recording, the menu key is operated following the power key of the remote controller 22. Receiving these command signals, the back-end microcomputer 16 displays a “menu” and various items on the screen 23a of the monitor 23 shown in FIG.

  Here, when the user operates the cursor key or the enter key and selects “sound effect setting” from the menu items, the back-end microcomputer 16 displays details relating to the sound effect as shown in FIG.

  Among these items, when the user sets “whether to ring” to “YES”, the back-end microcomputer 16 performs a setting to sound a sound effect during recording of information on the DVD 1.

  Next, when “all” is selected from “all” or “individual”, the setting is the same as the factory shipment.

  The initial settings for this sound effect are “Pi” for the lead-in area, “Phi” for the user data area, “Pipi” for the lead-out area, and “Pi” for the error.

  Subsequently, the initial setting of the number of ringing is set to “1 time” for the lead-in area and “24 times” for the user data area (in the example of recording AV information for 2 hours, the number of ringing every 5 minutes. However, even if the double speed is changed, the sounding is controlled so that the same time interval is obtained), and the lead-out area is “once”.

  It should be noted that the number of ringing errors is set to be 5 seconds apart.

  On the other hand, when the user selects “individual” from among “all” or “individual”, each setting becomes possible.

  However, the items that are not selected remain the default settings, and there is no need to change the timbre of the sound effect such as “pipi” in the user data area.

  Since the recording time of the lead-in area and the lead-out area is as short as a few seconds, it is normally left at the initial setting.

  Here, when “individual” is selected and the user data area is selected, the ringing interval is set instead of the ringing count.

  If the user feels that the default 5-minute interval is annoying, for example, the ringing interval is set to a 10-minute interval.

  At this time, the numeric keypad or the up / down key is operated to input 10 in the item for the ringing interval.

  When the enter key is operated, the back-end microcomputer 16 stores numerical data at a predetermined address in the work RAM 17. As a result, the sound effect is set to sound at 10-minute intervals that is twice the initial setting.

  As for errors, the ringing interval can be set, and may be changed so as to be earlier than the initial setting of 5 seconds or conversely.

  At this time, after selecting an error item, if the key is operated and 5 is entered in the second item of the ringing interval, the sound effect is set to ring at intervals of 5 seconds when an error occurs.

  After the individual setting as described above, when the user performs a program recording start operation, the front-end microcomputer 9 controls the servo control unit 7 to start recording information on the DVD 1.

  Along with this, the back-end microcomputer 16 sends audio data to the D / A converter 14 based on the setting data in the work RAM 17, and sounds a sound effect from the speaker.

  When recording management information in the lead-in area, it sounds with a “pi” tone. Also, when recording AV information in the user data area, a “beep” sounds at 10 minute intervals. Furthermore, when recording end information in the lead-out area, a “beep” sounds.

  Thus, the user can easily determine which area is being executed when the recording of the program is started.

  Further, when an error detection signal is sent from the DSP 6 or the track buffer RAM 8 during such information recording, a beep sound is emitted at a preset interval of 5 seconds.

  Therefore, the user can notice that there was a mistake in writing AV information during recording of the broadcast program.

  Note that if the dedicated key is operated during this information recording, the sound effect sound can be paused or sounded again.

  Next, settings for reproducing recorded information from the DVD 1 will be described.

  At this time, the menu key is operated to select “sound effect setting” on the screen 23a shown in FIG.

  Then, if “YES” is set to “YES” on the screen 23a shown in FIG. 3 by a key operation, a setting for sounding a sound effect during information reproduction of the DVD 1 is performed.

  Next, when “all” is selected from “all” or “individual”, the setting is as it was at the time of shipment from the factory, and a sound effect can be produced with the same contents as at the time of recording.

  On the other hand, when the user selects the “individual” side, the playback time of the lead-in area and the lead-out area is left as the initial setting, and when the user data area is selected, the ringing interval is set.

  In order to make this ringing interval the same as at the time of recording, 10 is entered in the minute item and set to the 10 minute interval. The error is also changed so as to be earlier than the initial setting of 5 seconds or conversely.

  By the way, for the setting at the time of reproduction, it is also possible to select the type of sound effect tone color.

  When the user selects “Sound Type” from the menu, the recording mode, the time division diagram that differs for each mode, and the tone type are displayed on the screen 23a.

  For example, the recording mode XP (high image quality: 1 hour) has 2 divisions, SP (standard: 2 hours) has 4 divisions, LP (long time: 4 hours) has 8 divisions, and the like.

  Here, for example, when the user selects SP of standard 2 hours, the display is made in 4 divisions in which 1 division is 30 minutes.

  When, for example, A, 2nd B, 3rd C, and finally D are input at the beginning of these four sections, different sound effects are set every 30 minutes. When the user selects a long-time recording mode, a plurality of sections based on 30 minutes are displayed, and different timbres can be set for each section.

  After the individual setting as described above, when the user performs a reproduction start operation of the program, the reproduction of the DVD 1 is started.

  Along with this, the audio data based on the setting data is sent to the D / A converter 14, so that the tone of “pi” sounds when the management information of the lead-in area is reproduced.

  In addition, when AV information of the user data area is reproduced, “pipi” sounds at 10-minute intervals.

  If the “sound type” has been set, when the AV information of the user data area is reproduced, a sound effect having a different tone color sounds every 30 minutes.

  Furthermore, when the end information of the lead-out area is reproduced, “beep” sounds.

  As a result, the user can easily determine which area is being executed when the reproduction of the program is started.

  Further, when an error detection signal is sent from the DSP 6 or the track buffer RAM 8 during such information recording, a beep sound is generated at a preset interval of 5 seconds.

  Therefore, the user can notice that there was an AV information reading error during the reproduction of the broadcast program.

  If the dedicated key is operated during the information reproduction, the sounding of the sound effect can be paused or sounded again as in the recording.

  The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.

It is a block diagram which shows the electric constitution of the disc apparatus which is one Embodiment of this invention. It is a screen figure of the menu displayed on the monitor. It is a setting screen figure of the sound effect displayed on the monitor.
