BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the best embodiment of the present application will be described with reference to the accompanying drawings. The embodiment described below is an embodiment when the present application is applied to an information reproducing / recording apparatus.

First, the configuration and function of the information reproducing / recording apparatus according to the present embodiment will be described with reference to FIG. FIG. 1 shows a schematic block example of the information reproducing / recording apparatus according to the present embodiment. FIG.

As shown in FIG. 1, the information reproduction / recording apparatus 1 includes an information reproduction unit 11, an information output unit 12, a music feature amount extraction unit 13, an information recording / reproduction unit 14, an operation / display unit 15, a microphone 16, and a voice. The system includes a recognition unit 17, a communication unit 18 for performing data communication with the information distribution server 2 via the network 3, and a system control unit 19.

[0027] The information reproducing unit 11 is controlled by the system control unit 19 under the control of CD (Compact Disc: CD-DA (Digital Audio), CD-R, CD-R / W, etc.), MD (Mini Disc). Recording media such as DVD (Digital Ver satile Disc: DVD-Audio, DVD-Video, DVD-R, DVD-RW, etc.) or card-type recording media (eg memory sticks and SD cards) ) Recorded music data (an example of the presentation data of the present application) is reproduced, and the music data is output to the information output unit 12, the music feature amount extraction unit 13, and the information recording / reproduction unit 14.

[0028] For example, when the information reproducing unit 11 reproduces music data recorded on a CD (for example, CD-DA), the information reproducing unit 11 transmits a light beam to the CD (not shown). An optical amplifier that irradiates and optically reads recorded information, photoelectrically converts it into an electrical signal and outputs it, an RF signal that generates and outputs an electrical signal force RF (Radio Frequency) signal output from the optical pickup, and the like Performs predetermined demodulation processing and error correction processing on the RF signal, converts it into a digital signal and reproduces the music data (for example, a DSP (Digital Signal Processor)), a spindle motor and an optical pickup Servo circuit that servo-controls the backup, etc., to play and output the music data

[0029] Further, the information reproducing unit 11 includes accompanying information attached to the music data on the recording medium (for example, text information such as music titles and giannoles (eg, rock, jazz, pops, classics, hip-hop, etc.)). , Artist name, etc.) is recorded, the information reproducing unit 11 reads the recording medium power of the accompanying information and outputs it to the information recording / reproducing unit 14 under the control of the system control unit 19. ing.

[0030] It should be noted that since the configuration and function for reproducing music data from a recording medium other than a CD are known techniques, detailed description thereof is omitted. Multimedia player In this way, music data may be played back from multiple recording media.

[0031] Although not shown, the information output unit 12 is a piece of music data reproduced and output by the information reproducing unit 11.

(Digital audio signal) is input and converted into an analog audio signal DAC (Digital-to-Analog Converter), AMP (Amplifier) that amplifies and outputs the analog audio signal, and the amplified analog audio signal It is equipped with a speaker that outputs sound waves, and music is output from the speaker!

[0032] The music feature amount extraction unit 13 is configured by, for example, a DSP or the like, and inputs the music data reproduced and output by the information reproduction unit 11, and the music feature indicating the characteristics of the music data from the music data The amount is extracted and output to the information recording / reproducing unit 14 and the system control unit 19.

Here, the music feature amount is information (for example, a numerical value between 0 and 100) that quantitatively indicates the feature of the music, and includes, for example, a musical tone of the music Musical sound features obtained from

[0034] Musical sound features include key (tune tonality in C major, A minor, etc.), key change position (or change pattern), chord (chord or chord string), change of the chord Position (or variation pattern), amount of change (CPM) (or rate of change (HVL)), beat (beat: constant pulse signal with strength), maximum value (or minimum value) of the beat , Average value), change position (or change pattern) of the beat, change amount (BPM) (or change rate) of the beat, maximum intensity or average intensity of music, volume, change position (or change) of the sound Pattern).

[0035] Since various known methods can be applied to the extraction of these musical sound feature values, detailed description thereof will be omitted. For example, the music feature value extraction unit 13 performs fast Fourier transform ( (Fast Fourier Transform) and frequency analysis to calculate the volume value for each frequency at a predetermined time interval along the time axis, and the key and its related amount (key change position etc.), the code and its related amount (Code The position of the beat and the amount of change (such as the maximum value of the beat (signal)) by extracting the waveform envelope related to the music data at a predetermined threshold level. Perform extraction.

[0036] In addition to the above-described music feature quantity, the music feature quantity extraction unit 13 performs, for example, a music tempo. Further, the position and the number of rust portions of the music, the key of the rust portion, the beat, the chord, and the quantities related thereto may be extracted by a known method.

[0037] The information recording / playback unit 14 includes, for example, a buffer memory for temporarily storing music data, an encoder Z decoder for encoding (compression, etc.) or decoding (decompression, etc.) music data, HD (Hard Disc) and HD drive etc. for recording music data on HD or playing back HD power. The information recording / reproducing unit 14 may be configured to include a recording medium such as MD, DVD-RW, or a card type recording medium.

[0038] Then, the information recording / reproducing unit 14 compresses, for example, the music data output from the information reproducing unit 11 under the control of the system control unit 19 and records it on the HD, and also outputs it from the information reproducing unit 11. The associated information is recorded on the recording medium in association with the music data. The information recording / reproducing unit 14 records the music feature amount output from the music feature amount extracting unit 13 in association with the music data under the control of the system control unit 19.

Further, the information recording / reproducing unit 14 is distributed and communicated under the control of the system control unit 19, for example, from the information distribution server 2 via a network (for example, composed of the Internet, a mobile communication network, etc.) 3. The music data received via the unit 18 and accompanying information associated therewith are recorded on the recording medium. Note that the musical sound feature amount of the music data acquired from the information distribution server 2 is also extracted by the music feature amount extraction unit 13 at the time of acquisition, for example, and recorded in association with the music data.

[0040] In this way, each piece of music data recorded on the HD in the information recording / reproducing unit 14 is given a unique registration number (for example, a serial number) and is managed in a list. For example, management information such as a registration number, data capacity, recording location, performance time, the accompanying information, and music feature quantity recorded in HD is registered in the music list. The music list data is recorded in HD, for example, and is read and used by the system control unit 19 as appropriate. The management information may include the tone of the song data (for example, a bright song, a good song, a quiet song, a sad song, a healing song, etc.).

[0041] The operation / display unit 15 includes, for example, a touch panel type display panel (for example, a liquid crystal panel). Under the control of the system control unit 19, the management information included in the music list and various instructions are given by the user. The operation buttons for input etc. are displayed! Display panel When an operation button displayed on the screen is pressed, an instruction signal corresponding to the operation button is output to the system control unit 19.

[0042] The microphone 16 detects voices related to various instructions uttered by the user, for example.

(Sound collection) and the voice signal is output to the voice recognition unit 17.

[0043] The speech recognition unit 17 performs known speech recognition processing, performs frequency analysis of the speech signal from the microphone 16, and selects the most suitable candidate from a set of speech speech candidates prepared in advance. As a result, the information contained in the audio signal is recognized and output to the system control unit 19.

[0044] The system control unit 19 includes a CPU having a calculation function, a working RAM (an example of a storage unit), various processing programs (including a presentation data selection processing program), a ROM that stores data, and the like. . The presentation data selection processing program may be downloaded from a predetermined storage device connected to the network 8, for example, or may be recorded on a recording medium such as a CD-ROM and the drive of the recording medium. So that it can be read through.

[0045] Then, by executing a program stored in CPl ^ ¾OM or the like, the system control unit 19 as a computer performs overall control of the entire information reproducing / recording device 1, and also provides selection information acquisition means, It functions as data selection means, change information acquisition means, selection condition change means, notification means, and learning determination means.

[0046] In the present embodiment, the user operates / displays selection information for selecting one or a plurality of pieces of music data desired from among a large number of pieces of music data recorded on the HD. Or the microphone 16 and the voice recognition unit 17, and the system control unit 19 acquires the selection information input through the input unit as the selection information acquisition unit, and the selection information Based on the selection condition according to the selection, one or a plurality of music data is selected as the presentation data selection means.

Here, the selection information for selecting the music data is information necessary for specifying the music data to be selected by the system control unit 19, and for example, a music data , Rock, jazz, pop, classic, hip hop, etc.), music data Or the like (for example, a bright song, a good song, a quiet song, a sad song, a song to be healed), or information such as the artist name of the song data.

[0048] Each of the selection information is associated with a selection condition. For example, in the selection condition corresponding to the selection information indicating "bright tune", music data that matches the bright tune. (For example, 10 bright songs). Further, for example, the selection condition corresponding to the selection information indicating “lock” defines the number of music data matching the lock (for example, lock: 10 music). The association between each selection information and the selection condition is defined in the condition association table recorded in HD, for example.

[0049] Also, the determination as to whether or not the music data matches the bright music (or rock) is made based on the management information registered in the music list described above.

[0050] Further, according to the present embodiment, the user can use the operation 'display unit 15 or the microphone 16 and the voice recognition to display the fuzzy selection information in which fuzzy information having fuzziness is added to the selection information. In this case, the system control unit 19 acquires the input fuzzy selection information as selection information acquisition means, and based on the selection condition corresponding to the fuzzy selection information. Thus, one or a plurality of music data is selected as the presentation data selection means.

[0051] Specific examples of the ambiguous information include ambiguous expressions used by humans such as "almost", "centrally", "just", and "more".

[0052] FIG. 2 is a diagram showing an example of the condition association table when fuzzy information is considered. In the example shown in Fig. 2, the ambiguous selection information is divided into multiple levels, and different selection conditions are set corresponding to each level, and the level is increased (that is, level 1 to level). It is stipulated that the proportion of bright songs increases as the value increases to 4.

[0053] Further, for example, in the example of FIG. 2, the selection condition corresponding to the level 1 fuzzy selection information (almost bright songs) defines “all 10 songs, the proportion of bright songs 60%”. This means that the music data that matches the selection information (bright music) included in the fuzzy selection information out of all 10 music data selected is 60%. Therefore, in this case, 6 pieces of music data matching the selection information (for example, bright music) are selected. As a result, music data that does not match the selection information (for example, bright music) will be selected.

[0054] It should be noted that in the selection conditions at all levels, the proportion of music data that matches the selection information is defined to be larger than the proportion of music data that does not match the selection information.

[0055] The music data selected as described above is reproduced and output from the information recording / reproducing unit 14 under the control of the system control unit 19, and is selected by the user. Does not match (feel), for example, the user has increased the number of brighter songs! /, (In other words, the brightness selected based on the selection criteria, the number of songs added), or The case where it wants to reduce is assumed. For this reason, the user can input change information indicating the change in the selection condition through the operation 'display unit 15 or the voice recognition unit 17, and the system control unit 19 can input the change information. Information is acquired as change information acquisition means, and as the selection condition change means, the selection condition is changed based on the change information. Specific examples of the change information include “brighter (or darker) music”, “higher (or lower) level”, and the like.

Note that when the selection condition is changed as described above, for example, a change history (for example, change date and time, change contents, etc.) is stored in association with the condition association table.

[0057] When music data is selected as described above, the system control unit 19 provides notification information including the selection information or notification information including the ambiguous selection information to the user as notification means. It has come to inform. For example, when the system control unit 19 selects the music data based on the selection condition corresponding to the fuzzy selection information indicating “at the center of the bright song” input from the user, for example, “the music was selected at the center of the bright song”. Or, display information such as “Play around a bright song” on the display screen of the display unit 15 or output it as sound from the information output unit 12 to the user. Notify them.

[0058] Then, when the self-learning is not sufficient, the system control unit 19 serving as the notification means changes the acquired (input) selection information or the ambiguous selection information as appropriate and notifies it. It has become. For example, when fuzzy selection information indicating “at the center of a bright song” is acquired, fuzzy information (for example, almost) different from the fuzzy information (for example, at the center) included in the fuzzy selection information is selected information ( For example, notification information including fuzzy selection information (for example, a substantially bright song) added to a bright song is notified to the user. In addition, when selection information indicating “bright song” is acquired, ambiguity selection information (for example, at the center of a bright song) with ambiguity information (for example, at the center) added to the selection information. ) Is notified to the user.

It should be noted that the determination of whether or not the self-learning is sufficient is performed by the system control unit 19 as a learning determination unit based on, for example, the change frequency of the selection condition. For example, if the selection condition corresponding to certain ambiguous selection information has not been changed for a predetermined period (for example, 10 days), it is determined that learning is sufficient.

Next, the operation of the information reproducing / recording apparatus 1 configured as described above will be described with reference to FIG. 3 and the like.

When the processing shown in FIG. 3 is started, the system control unit 19 reads the above-described music list and condition association table from the information recording / reproducing unit 14 and waits for input from the user.

[0063] Then, for example, when the user utters "at the center of a bright song" as the fuzzy selection information, the voice is collected (input) by the microphone 16, and the fuzzy selection information is recognized by the voice recognition unit 17, The information is output to the system control unit 19. On the other hand, when the system control unit 19 obtains the fuzzy selection information indicating “at the center of a bright song” from the speech recognition unit 17 (step SI: Y), the system control unit 19 stores the information in, for example, RAM and proceeds to step S2. .

[0064] It should be noted that a plurality of operation buttons corresponding to the input candidates of the selection information and the ambiguous selection information are displayed on the display screen in the operation 'display unit 15, and the user has pressed the operation button out of the plurality of operation buttons. For example, an instruction signal corresponding to an operation button corresponding to the ambiguous selection information is output to the system control unit 19, and the system control unit 19 is configured to acquire preset ambiguous selection information corresponding to the instruction signal. Also good. [0065] In step S2, the system control unit 19 refers to the above condition association table, and selects the selection condition (for example, "all!" 10 songs, 70% of bright songs ”)), and select music data based on the selection conditions.

[0066] In the selection process, if the selection condition is, for example, “all 10 songs, 70% of bright songs”, for example, a registration number from the song data registered in the song list. Song data is identified in the new order (that is, the new song data order), and it is determined one by one whether the music data is a “bright song”, and the song data that matches the “bright song” 7 songs and 3 songs that do not match the “bright song” are selected.

[0067] Note that such a selection condition can be arbitrarily set by the user by operating the operation display 15 for example. In addition, the number of songs (for example, 10 songs) defined by the selection condition may be input together with the ambiguous selection information through the input means.

[0068] Here, the tune determination of whether or not the force matches the bright tune will be described in detail.

[0069] In this music tone discrimination process, for example, a music tone association table that prescribes and stores a music feature value and a music tone that define the correspondence is used, and the music of the specified music data in the music list is used. This is performed by the system control unit 19 based on the feature amount.

FIG. 4 is a diagram showing an example of the music tone association table. In the example shown in Fig. 4, the melody shows “bright song”, “sounding song”, “quiet song”, and “sad song”, and the song features are “key”, “ The chord change rate (HVL), “beat change (BPM)”, “maximum beat value”, and “average tone intensity (average level) J” are displayed.

Further, in FIG. 4, “high”, “medium”, and “low” mean music feature amount levels. For example, “high” is a numerical value range of 80 to: LOO, “Medium” is represented by a numerical value range of 30 to 79, and “Low” is represented by a numerical value range of 0 to 29. (Thus, “Medium to High” represents a numerical value range of 30 to: LOO, “Low”. "~" Represents a numerical range of 0-79). Also, in FIG. 4, “C major” or “B minor” is shown as an example of “key”, and this is also expressed, for example, in a certain numerical range.

[0072] When the music tone discrimination process is performed with reference to such a music tone association table, For example, it is determined whether or not the music feature value of the specified music data satisfies the music feature value level corresponding to “bright music” (in other words, falls within the numerical range shown in FIG. 4). If it is satisfied, the music data is determined to match the “bright music” (the same applies to other music tones).

[0073] Once the melody of the music data is thus determined, information indicating the determined music tune is registered in the music list in association with the music data, and thereafter the music data is recorded. With regard to, it is possible to determine the tune based on the information indicating the tune registered in the tune list without referring to the tune association table. In addition, even when selection information indicating genre (for example, lock) of music data or fuzzy selection information is also input by the user, genre discrimination is possible by referring to information indicating genres registered in the music list. Become.

Note that the system control unit 19 is configured to acquire information indicating the tune as the accompanying information accompanying the music data from the information distribution server 2 via the network 3, for example, and register it in the music list. May be.

[0075] By the way, in step S2, the power described in the example in which 7 pieces of music data matching “bright music” and 3 music data not matching “bright music” are selected respectively. The song data that does not match the song (selection information) may be selected as a song that is close to a bright song, or a song that is completely unrelated to the bright song (for example, a sad song) (If you select the genre of music data, the same applies.)

[0076] It should be noted that whether or not the song is close to "bright song" (selection information) is determined by, for example, not satisfying all the music feature levels corresponding to the bright song shown in FIG. ) Is performed based on whether or not it is a song that satisfies the level of some music feature quantities (for example, HVL, BPM).

[0077] Also, for example, whether or not the power is close to "Rock" (selection information) does not match "Rock" but matches "Jazz", but each song of music data that matches "Rock" Judgment is made based on whether or not the music data has a music feature value close to the feature value (the difference between the music feature values is a predetermined value or less).

[0078] When a plurality of pieces of music data are selected in step S2, the system control unit 19 selects The information related to the music data (for example, the registration number registered in the music list, the title, genre, music tone, performance time, etc. of the music) is registered in the playlist, for example.

[0079] Next, the system control unit 19 determines whether or not the self-learning is sufficient (step S3). For example, the system control unit 19 refers to the change date and time in the change history associated with the condition association table, and the period for which the selection condition set in the condition association table is preset (for example, 10 days) If it has not been changed, it is determined that learning is sufficient.

[0080] When it is determined that the learning is sufficient (step S3: Y), the system control unit 19 obtains the notification information including the ambiguous selection information indicating “at the center of the bright song” obtained in step S1 (for example, “bright The song is selected at the center of the song ”) is displayed on the display screen of the operation / display unit 15 or is output as voice from the information output unit 12 to notify the user (step S4).

[0081] On the other hand, when it is determined that the learning is not sufficient (step S3: N), the system control unit 19 detects the ambiguous information (center Notification information including ambiguous selection information (almost bright song) with ambiguous information (almost) different from (b) added to the selection information (almost bright song). Information is output to the user from the information output unit 12 to notify the user (step S5).

[0082] As described above, when learning is not sufficient, “at the center of the bright song” acquired in step S1 is “substantially bright song” included in the force notification information that is the level 2 fuzzy selection information in the example of FIG. "Is level 1 fuzzy selection information. That is, when learning is not sufficient, broadcast information including fuzzy selection information at a level lower than the level corresponding to the fuzzy selection information input by the user is broadcast. As a result, even if the selection of the music data does not match the user's intention (eating or different), it is possible to prevent the user from feeling uncomfortable.

[0083] If selection information indicating "bright tune" is acquired in step S1 and learning is not sufficient, according to the example shown in FIG. 2, a level lower than the level corresponding to the selection information is obtained. Notification information including “at the center of a bright song” indicating ambiguous selection information is notified to the user. It will be awkward.

[0084] Next, the system control unit 19 starts a reproduction process of the music data selected in step S2 and registered in the playlist (step S6).

[0085] In the reproduction process, the system control unit 19 controls the information recording / reproducing unit 14 to sequentially reproduce and output the music data registered in the playlist. Thus, the music data that is also reproduced and output by the HD force is output as sound waves to the outside through the information output unit 12, and the user listens to the music.

[0086] Then, for example, when the user wants to increase a brighter song, when the user speaks "brighter song" as the change information described above, the sound is collected (input) by the microphone 16, and the voice is recorded. The change information is recognized by the recognition unit 17 and the information is output to the system control unit 19. On the other hand, when the system control unit 19 obtains the change information indicating “brighter, song” from the speech recognition unit 17 (step S7: Y), based on this, the selection condition in the above condition association table is obtained. (Step S8), and this change history is recorded in the HD in association with the correspondence table.

FIG. 5 is a diagram illustrating an example in which the selection condition in the condition association table is changed. In the example shown in FIG. 5, when the change information is “brighter song”, it corresponds to the fuzzy selection information (“almost bright song”, “in the center of bright song”) and selection information (“bright song”). The ratio of bright songs in the selection conditions has been changed to increase.

[0088] Thus, for example, even with the same fuzzy selection information (for example, “at the center of a bright song”), it is possible to vary the selection conditions for each user, and set the selection conditions suitable for each user. Can be determined. The subsequent selection of music data is based on the changed selection conditions.

[0089] In the example shown in Fig. 5, the force that has been changed so that the proportion of bright songs increases by 20% in each selection condition. This increase width (change width) is also defined by the content of the change information. You may make it. For example, if the change information is “Brighter song”, the increase width (change width) is “20%”, and if the change information is “Slighter song”, the increase width (change width) is “ It is configured to be set in advance to be “10%”.

[0090] In addition, on the display screen of the operation / display unit 15, multiple copies corresponding to input candidates for change information are displayed. A number of operation buttons are displayed, and an instruction signal corresponding to, for example, an operation button corresponding to change information pressed by the user from among the plurality of operation buttons is output to the system control unit 19, and the system control unit 19 It may be configured to acquire preset change information corresponding to the signal.

[0091] Next, the system control unit 19 determines whether or not the reproduction of all the music data registered in the playlist has ended (step S9), and if not completed (step S9: N) Then, the process returns to step S7, and when the process ends (step S9: Y), the process ends.

[0092] As described above, according to the above-described embodiment, a condition association table in which a plurality of different fuzzy selection information and a selection condition associated with each fuzzy selection information are set in advance. Prepared so that when the user's ability is input with fuzzy selection information for music selection, the music data is selected based on the selection condition corresponding to the fuzzy selection information with reference to the condition association table. Therefore, the music data can be accurately selected according to the user's mood at that time.

Further, since the selection condition set in the condition association table is changed based on the change information input from the user, even if the same ambiguity selection information is provided for each user, Selection conditions can be made different for each user, and selection conditions suitable for each user can be set.

[0094] Further, when learning is not sufficient, the notification information including the fuzzy selection information at a level lower than the level corresponding to the selection information or fuzzy selection information that is also input by the user is notified. Even if the selection of data does not match the intention of the user (food or different), the user can feel uncomfortable.

Note that, when it is determined in step S3 that learning is not sufficient, the notification information may be changed according to a plurality of levels of learning (learning level). For example, if it is assumed that the condition that learning is sufficient is that the selection condition corresponding to certain selection information (for example, a bright song) has not been changed for more than 10 days, the change has been made. When the period is 5 days or more and less than 10 days (determined that the degree of learning is high), broadcast information including fuzzy selection information (for example, in the center of a bright song) one level lower than the level corresponding to the selection information. Informed and less than 5 days (learning If it is determined that the degree is low, notification information including fuzzy selection information (for example, almost bright music) two levels below the level corresponding to the selection information may be notified. Furthermore, the notification information corresponding to the degree of learning corresponding to each case may be notified by dividing into more stages.

[0096] Further, in step S2, the power described in the example in which the music data is specified in the order of the registration number from the music data registered in the music list is not limited to this. As an example of this, all the song data recorded in HD (registered in the song list) can be set with information indicating “priority of selection according to each selection information”, and The music data may be specified in descending order of priority (for example, expressed by a numerical value from 1 to 10), and it may be configured to determine whether the music data is, for example, a “bright music” (for example, If all song data is recorded in 100 songs HD, it is identified in the order of selection priority and the above determination is made.For example, when 10 songs are selected, song data with a low selection priority is selected. Is not to be specified Selection process to completion).

Then, for example, when the music data selected based on the selection condition corresponding to the selection information indicating “bright music” in step S6 is reproduced and output, the user inputs input means such as an operation button. When the information indicating that `` bright song '' does not fit (not fit) is input, the priority of the selection corresponding to `` bright song '' in the song data is lowered (lowered), If information indicating that it fits (fits) the “bright song” is entered, it is possible to increase the priority of the selection corresponding to the “bright song” in the song data. Music data that matches the intention (sense) of the song will be selected.

[0098] Further, in the above embodiment, the power described in the example in which a plurality of pieces of music data are selected according to the selection condition is not limited to this, and one piece of music data is selected. Also good. In this case, as the ambiguous selection information, for example, “very bright song”, “normally bright song”, “bright song”, “slightly bright song”, “slightly bright song”, etc. Different selection conditions are set corresponding to each level.

[0099] The selection condition corresponding to the fuzzy selection information indicating "pretty bright music" includes, for example, In Fig. 4, it is specified that all of “Cord change rate”, “Beat change amount”, “Maximum beat value” and “Average tone intensity” are “High”, and “Slightly bright, In the selection condition corresponding to the ambiguous selection information indicating “”, all of “chord change rate”, “beat change amount”, “maximum beat value”, and “average tone intensity” are “medium”. It is specified that there is. In this case, when change information (for example, “brighter song”) is input, the selection condition may be changed as in the case of multiple selection. Without changing the conditions, the level of the fuzzy selection information is raised (or lowered), and the music data is selected again based on the selection conditions corresponding to the fuzzy selection information of the raised (or lowered) level. May be. Furthermore, when the selected music data is being played back and output, when the user inputs ambiguous selection information indicating “at the center of this music” through an input means such as an operation button, the music characteristics of the music data are displayed. It may be configured to select a predetermined number (for example, 10 songs) of music data that is close to the amount (the difference between each music feature amount is a predetermined value or less).

[0100] In the above embodiment, the power described in the case of applying to music data as an example of presentation data presented to the user is not limited to this. For example, content such as a movie or a program You may make it apply with respect to data. Specific examples of the ambiguous selection information in this case include genres such as “action”, “SF”, “variety”, “comedy”, “love story”, etc. (the ambiguous information is the same as the above embodiment). The same).

[0101] In addition, the information reproducing / recording device 1 of the present application can be applied to personal computers, PDAs, and the like as well as in-vehicle, home, or portable audio devices. Is applicable.

[0102] The present invention is not limited to the above embodiment. The above embodiment is merely an example, and the present invention has the same configuration as the technical idea described in the claims of the present invention, and any device that exhibits the same function and effect is the present invention. It is included in the technical scope of the invention.
