  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 this embodiment will be described with reference to FIG. FIG. 1 is a diagram showing a schematic block example of the information reproducing / recording apparatus according to the present embodiment.

  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 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 are provided.

  Under the control of the system control unit 19, the information reproducing unit 11 is a CD (Compact Disc: a generic term for CD-DA (Digital Audio), CD-R, CD-R / W, etc.), MD (Mini Disc), DVD (Digital Versatile Disc: Generic name for DVD-Audio, DVD-Video, DVD-R, DVD-RW, etc.) or music recorded on a recording medium (recording means) such as a card-type recording medium (for example, memory stick, SD card, etc.) Data (an example of 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.

  For example, when the information reproducing unit 11 reproduces music data recorded on a CD (for example, CD-DA), the information reproducing unit 11 records the CD by irradiating the CD with a light beam (not shown). An optical pickup that optically reads information, photoelectrically converts it into an electrical signal and outputs it, an RF amplifier that generates and outputs an RF (Radio Frequency) signal from the electrical signal output from the optical pickup, and a predetermined demodulation to the RF signal A digital signal processing circuit (for example, constituted by a DSP (Digital Signal Processor), etc.) that performs processing and error correction processing, converts it into a digital signal and reproduces music data, and a servo circuit that servo-controls the spindle motor and optical pickup The music data is reproduced and output.

  The information reproducing unit 11 also includes accompanying information accompanying the music data on the recording medium (for example, text information such as music title, genre (eg, rock, jazz, pop, classic, hip hop, etc.)), artist name, etc. ) Is recorded, the information reproducing unit 11 reads the accompanying information from the recording medium and outputs it to the information recording / reproducing unit 14 under the control of the system control unit 19.

  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. Further, music data may be reproduced from a plurality of recording media like a multimedia player.

  Although not shown, the information output unit 12 inputs music data (digital audio signal) reproduced and output by the information reproduction unit 11 and converts the data into an analog audio signal (DAC) (Digital-to-Analog Converter). An AMP (Amplifier) that amplifies and outputs an audio signal, a speaker that outputs the amplified analog audio signal as a sound wave, and the like are provided, and music is output from the speaker.

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

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

  The musical sound feature amount includes a key (a tonality of a song such as C major and a minor), a key change position (or change pattern), a chord (a chord or a combination of chords), a change position (or a change pattern) ), Chord change (CPM) (or rate of change (HVL)), beat (beat: constant pulse signal with strength), maximum value (or minimum value, average value) of the beat, and the beat Change position (or change pattern), change amount (BPM) (or change rate) of the beat, maximum intensity or average intensity of the tone, volume, change position (or change pattern) of the volume, and the like.

  Since various known methods can be applied to the extraction of the musical sound feature values, detailed description thereof is omitted. For example, the music feature value extraction unit 13 converts the music data into a fast Fourier transform (Fast Fourier Transform). Then, frequency analysis is performed 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 change position and change) The amount of beat and the amount related thereto (the maximum value of the beat (signal)) are extracted by detecting the envelope of the waveform related to the music data at a predetermined threshold level.

  In addition to the above-described music feature quantity, the music feature quantity extraction unit 13 may, for example, set the tempo and rhythm of the music, and the position and frequency of the chorus part of the music, the key of the chorus part, the beat, the chord, and the like. You may comprise so that the quantity regarding may be extracted by a well-known method.

  The information recording / reproducing unit 14 includes, for example, a buffer memory for temporarily storing music data, an encoder / decoder for encoding (compressing) or decoding (decompressing) music data, an HD (Hard Disc), and an HD. An HD drive or the like for recording or reproducing music data or the like from the HD is provided. The information recording / reproducing unit 14 may be configured to include a recording medium such as an MD, a DVD-RW, or a card type recording medium.

  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 the compressed data on the HD, and the accompanying information output from the information reproducing unit 11. It 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 from the information distribution server 2 through the network 3 (for example, composed of the Internet, a mobile communication network, etc.) 3 through the communication unit 18 under the control of the system controller 19. The received music data 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.

  As described above, each piece of music data recorded on the HD in the information recording / reproducing unit 14 is assigned a unique registration number (for example, a serial number) and is managed in a list. For example, management information such as the registration number, data capacity, recording location, performance time, the accompanying information, and the music feature amount recorded on the HD is recorded in the music list. The music list data is recorded in, for example, an HD, and is appropriately read and used by the system control unit 19. Note that 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.).

  The operation / display unit 15 includes, for example, a touch panel 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 for the user to input various instructions are displayed. Operation buttons are displayed. When an operation button displayed on the display panel is pressed, an instruction signal corresponding to the operation button is output to the system control unit 19.

  For example, the microphone 16 detects (collects) voices related to various instructions uttered by the user and outputs the voice signals to the voice recognition unit 17.

  The voice recognition unit 17 performs known voice recognition processing, performs frequency analysis of the voice signal from the microphone 16, and selects the most suitable candidate from the prepared speech voice candidate group. Information included in the audio signal is recognized and output to the system control unit 19.

  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. Note that the presentation data selection processing program may be downloaded from a predetermined server connected to the network 8, for example, or recorded on a recording medium such as a CD-ROM and via a drive of the recording medium. May be read.

  Then, when the CPU executes the program stored in the ROM or the like, the system control unit 19 as a computer performs overall control of the information reproducing / recording apparatus 1 as well as selection information acquisition means, presentation data selection means of the present application, It functions as change information acquisition means, selection condition change means, notification means, and learning determination means.

  In the present embodiment, the user uses the operation / display unit 15 as input means to select selection information for selecting one or more desired music data from among a large number of music data recorded on the HD, or It is possible to input through 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 condition according to the selection information Based on the above, 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 includes, for example, the genre of the music data (for example, rock, jazz). , Pops, classics, hip hop, etc.), music data tone (for example, bright songs, good songs, quiet songs, sad songs, healing songs, etc.) To do.

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

  Whether or not the music data matches the bright music (or rock) is determined based on the management information registered in the music list described above.

  Furthermore, in this embodiment, the user inputs the fuzzy selection information in which fuzzy information having fuzziness is added to the selection information by the operation / display unit 15 or the microphone 16 and the voice recognition unit 17. In this case, the system control unit 19 acquires the input fuzzy selection information as selection information acquisition means, and based on the selection conditions according to the fuzzy selection information, one or a plurality of music pieces Data is selected as the presentation data selection means.

  Specific examples of the ambiguous information include ambiguous expressions used by humans such as “almost”, “at the center”, “just”, “more”, and the like.

  FIG. 2 is a diagram illustrating an example of a condition association table when fuzzy information is considered. In the example shown in FIG. 2, the ambiguous selection information is divided into a plurality of levels. Different selection conditions are set corresponding to each level, and the higher the level is (that is, level 1 to level 4). It is stipulated that the proportion of bright songs increases.

  Further, for example, in the example of FIG. 2, the selection condition corresponding to the level 1 fuzzy selection information (almost bright music) defines “all 10 songs, the proportion of bright music 60%”. The proportion of the music data that matches the selection information (bright music) included in the fuzzy selection information out of the total 10 music data selected is 60%. Accordingly, in this case, six pieces of music data that match the selection information (for example, bright music) are selected, and four pieces of music data that do not match the selection information (for example, bright music) are selected. Become.

  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.

  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 presented to the user. For example, the user wants to increase the number of brighter songs (in other words, the number of bright songs selected based on the selection condition is insufficient) or to reduce the number of brighter songs. For this reason, the user can input change information indicating the change of 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. Is obtained 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.

  When the selection condition is changed in this way, for example, a change history (for example, change date and time, change contents, etc.) is stored in association with the condition association table.

  Further, when music data is selected as described above, the system control unit 19 notifies the user of notification information including the selection information or notification information including the ambiguous selection information as notification means. It has become. For example, when the system control unit 19 selects music data based on the selection condition corresponding to the fuzzy selection information indicating “at the center of a bright song” input by the user, for example, “I selected the song at the center of a bright song” or Notification information such as “plays in the center of a bright song” is displayed on the display screen of the operation / display unit 15 or output as sound from the information output unit 12 to notify the user of the information. To do.

  And the system control part 19 as an alerting | reporting means changes and notifies the acquired selection information or the ambiguous selection information suitably, when self learning is not enough. 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) in which ambiguity information having ambiguity (for example, at the center) is added to the selection information. ) Is notified to the user.

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

  FIG. 3 is a flowchart showing processing in the system control unit 19 of the information reproducing / recording apparatus 1.

  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.

  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. It is output to the control unit 19. On the other hand, when acquiring the fuzzy selection information indicating “at the center of a bright song” from the voice recognition unit 17 (step S1: Y), the system control unit 19 stores the information in, for example, a RAM and proceeds to step S2.

  A plurality of operation buttons corresponding to input candidates for selection information and fuzzy selection information are displayed on the display screen of the operation / display unit 15, for example, fuzzy selection information pressed by the user from among the plurality of operation buttons. An instruction signal corresponding to the operation button corresponding to is output to the system control unit 19 so that the system control unit 19 acquires preset fuzzy selection information corresponding to the instruction signal.

  In step S <b> 2, the system control unit 19 refers to the condition association table, and selects the selection condition according to the acquired fuzzy selection information indicating “at the center of the bright song” (for example, “all 10 songs, occupied by bright songs”). The ratio 70% ") is specified, and music data selection processing is performed based on the selection condition.

  In the selection process, when the selection condition is, for example, “all 10 songs, the proportion of bright songs 70%”, for example, from the song data registered in the song list, for example, in the order of registration numbers (that is, Music data is identified in the order of new music data), and it is determined one by one whether or not the music data is “bright music”, and there are 7 music data that match “bright music”, “bright music” "3 pieces of music data not matching" "are selected.

  Such a selection condition can be arbitrarily set by the user, for example, by operating the operation / display unit 15. Further, 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 from the user.

  Here, the tone determination of whether or not it matches a bright song or the like will be described in detail.

  In this music tone discrimination process, for example, a music tone association table that prescribes and stores music song feature values and music tone correspondences is used, and the music feature values of the specified music data in the song list are used. This is performed by the system control unit 19 based on this.

  FIG. 4 is a diagram illustrating an example of the music tone association table. In the example shown in FIG. 4, “bright song”, “smooth song”, “quiet song”, “sad song” are shown as the tune, and “key”, “chord of chord” are shown as song features. "Change rate (HVL)", "beat change amount (BPM)", "maximum beat value", and "average tone intensity (average level)" are shown.

  Further, in FIG. 4, “high”, “medium”, and “low” mean music feature amount levels, for example, “high” is a numerical range of 80 to 100, and “medium” is In the numerical range of 30 to 79, “low” is represented by a numerical range of 0 to 29, respectively (so “medium to high” represents a numerical range of 30 to 100, “low to medium” Represents a numerical range of 0-79). In FIG. 4, “C major” or “B minor” is shown as an example of the “key”, and this is also expressed by a certain numerical range, for example.

  When music tone discrimination processing is performed with reference to such a music tone association table, for example, whether the music feature amount of the specified music data satisfies the level of the music feature amount corresponding to “bright song” ( In other words, whether or not it falls within the numerical range shown in FIG. 4 is determined, and if satisfied, the music data is determined to match the “bright music” (the same applies to other music tones). .

  Once the melody of the music data is determined in this way, the information indicating the determined music tune is registered in the music list in association with the music data. Even without referring to the attached table, it is possible to determine the tune based on the information indicating the tune registered in the music list. Further, even when selection information indicating the genre (for example, rock) or ambiguous selection information of the music data is input from the user, the genre can be determined by referring to the information indicating the genre registered in the music list. .

  Note that the system control unit 19 may be 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 and register it in the music list.

  By the way, in the above-described step S2, there has been described an example in which 7 pieces of music data matching “bright music” and 3 music data not matching “bright music” are selected. As the music data that does not match the selection information), a song close to “bright song” may be selected, or a song completely unrelated to “bright song” (for example, “sad song”) is selected. The same may be applied to the genre of music data.

  Whether or not the song is close to “bright song” (selection information) does not satisfy all the music feature level levels corresponding to the bright song shown in FIG. 4 (does not fall within the numerical range). This is performed depending on whether or not the music satisfies the level of some of the music feature quantities (for example, HVL, BPM).

  Also, for example, whether or not the song is close to “Rock” (selection information) is, for example, not matched with “Rock” but matched with “Jazz”, but each song feature amount of song data matching “Rock” It is determined by whether or not the music data has a similar music feature value (the difference between the music feature values is a predetermined value or less).

  When a plurality of pieces of music data are selected in step S2, the system control unit 19 performs information on the selected music data (for example, a registration number registered in the music list, a title of the music, a genre, a music tone, a performance time). Etc.) is registered in a playlist, for example.

  Next, the system control unit 19 determines whether or not 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.

  When it is determined that the learning is sufficient (step S3: Y), the system control unit 19 receives the notification information including the ambiguous selection information indicating “at the center of the bright song” acquired at step S1 (for example, “select the song at the center of the bright 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).

  On the other hand, when it is determined that the learning is not sufficient (step S3: N), the system control unit 19 refers to the ambiguous information (at the center) included in the ambiguous selection information indicating “at the center of the bright song” acquired at step S1. Information information including ambiguous selection information (almost bright music) in which different ambiguous information (almost) is added to selection information (bright music) is displayed on the display screen of the operation / display unit 15, or the information output unit 12. To the user by outputting as voice (step S5).

  Thus, when learning is not sufficient, “at the center of the bright song” acquired in step S1 is the level 2 fuzzy selection information in the example of FIG. 2, but the “almost bright song” included in the notification information 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. Thereby, even when the selection of music data does not match the user's intention (disagreement), it is possible to prevent the user from feeling uncomfortable.

  If selection information indicating “bright tune” is acquired in step S1 and learning is not sufficient, according to the example shown in FIG. 2, ambiguity selection information at a level lower than the level corresponding to the selection information is obtained. The notification information including “at the center of a bright song” is notified to the user.

  Next, the system control unit 19 starts reproduction processing of the music data selected in step S2 and registered in the playlist (step S6).

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

  For example, when the user wants to increase brighter music, if the user speaks “brighter music” as the change information, the voice is collected (input) by the microphone 16, and the voice recognition unit 17. Then, the change information is recognized and the information is output to the system control unit 19. On the other hand, when the system control unit 19 obtains change information indicating “brighter music” from the speech recognition unit 17 (step S7: Y), the system control unit 19 changes the selection condition in the condition association table based on the change information. (Step S8), this change history is recorded in the HD in association with the association 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”, “around the bright song”) and selection information (“bright song”). The ratio of bright songs in the selection conditions has been changed to increase.

  Thereby, even if it is the same fuzzy selection information (for example, "at the center of a bright tune"), it becomes possible to change selection conditions for every user, and the selection conditions suitable for every user can be set. The subsequent selection of music data is based on the changed selection condition.

  In the example shown in FIG. 5, each selection condition is changed so that the proportion of bright music is increased by 20%, but this increase width (change width) is also defined by the content of the change information. Anyway. For example, when the change information is “brighter music”, the increase width (change width) is “20%”, and when the change information is “a little brighter music”, the increase width (change width) is “10”. % "Is set in advance.

  Also, a plurality of operation buttons corresponding to change information input candidates are displayed on the display screen of the operation / display unit 15, and an operation button corresponding to, for example, change information pressed by the user from among the plurality of operation buttons. An instruction signal corresponding to the instruction signal may be output to the system control unit 19, and the system control unit 19 may acquire preset change information corresponding to the instruction signal.

  Next, the system control unit 19 determines whether or not the reproduction of the music data registered in the playlist has been completed (step S9), and if not completed (step S9: N), step S7. When the process is finished (step S9: Y), the process is finished.

  As described above, according to the embodiment, a condition association table in which a plurality of different ambiguity selection information and selection conditions associated with each ambiguity selection information are prepared in advance, When fuzzy selection information is input from the user for music selection, the music data is selected based on the selection conditions corresponding to the fuzzy selection information with reference to the condition association table. The music data can be accurately selected according to the user's mood.

  In addition, since the selection conditions set in the condition association table are changed based on the change information input by the user, even if the same ambiguity selection information is selected for each user, for example, The conditions can be made different, and selection conditions suitable for each user can be set.

  In addition, when learning is not sufficient, notification information including fuzzy selection information at a level lower than the level corresponding to selection information or fuzzy selection information input from the user is notified, so selection of music data Even when the user does not match the user's intention (disagree), the user can be prevented from feeling uncomfortable.

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

  Further, in step S2, the example in which music data is specified from the music data registered in the music list in ascending order of the registration number has been described. However, the present invention is not limited to this. As an example, information indicating “priority of selection according to each selection information” can be set for all the music data recorded in the HD (registered in the music list). The music data may be specified in descending order (for example, expressed by 1 to 10 numerical values), and it may be configured to determine whether the music data is, for example, “bright music” (for example, the music data is Assuming that all 100 songs are recorded in HD, the above determination is performed in the order of selection priority. For example, when 10 songs are selected, music data with a low selection priority is identified. Rukoto no selection process is completed).

  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 can select “bright music” through the input means such as an operation button. When the information indicating that it does not match (does not fit) is input, the priority of the selection corresponding to the “bright song” of the music data is lowered (lowered), and it matches (bits) the “bright song”. If the information indicating that the selection is made to increase (increase) the priority of selection corresponding to the “bright song” of the song data, the song data that more matches the user's intention (feel) Will be selected.

  Moreover, in the said embodiment, although the example in case several music data were selected by selection conditions was demonstrated, it is not limited to this, It may comprise so that one music data may be selected. good. In this case, as the ambiguous selection information, for example, “pretty bright songs”, “normally bright songs”, “bright songs”, “slightly bright songs”, “slightly bright songs”, etc. Different selection conditions are set corresponding to each level.

  The selection conditions corresponding to the ambiguous selection information indicating “pretty bright music” include, for example, “chord change rate”, “beat change amount”, “maximum beat value”, and “musical tone” in FIG. All of the “average intensity” are defined to be “high”, and the selection conditions corresponding to the ambiguous selection information indicating “slightly bright music” include “chord change rate”, “beat change amount”, “ It is specified that all of the “maximum value of beat” and “average tone intensity” are “medium”. 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 condition, the level of the fuzzy selection information is raised (or lowered), and the music data is selected again based on the selection condition corresponding to the fuzzy selection information of the raised (or lowered) level. May be. Further, when the selected music data is reproduced 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, You may comprise so that a predetermined number (for example, 10 music) of music data which are close (the difference of each music feature-value is below a predetermined value) may be selected.

  In the above-described embodiment, the case where the present invention is applied to music data as an example of presentation data presented to the user has been described. However, the present invention is not limited to this. For example, content data such as a movie or a program may be used. You may make it apply with respect. 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 in the above embodiment) ).

  In addition, the information reproducing / recording apparatus 1 of the present application can be applied not only to in-vehicle, home-use, or portable audio devices, but also to personal computers, PDAs, and the like, and also to in-vehicle navigation devices. Is possible.

  The present invention is not limited to the above embodiment. The above-described embodiment is an exemplification, and the present invention has any configuration that has substantially the same configuration as the technical idea described in the claims of the present invention and exhibits the same function and effect. Are included in the technical scope.

  In addition, the entire disclosure of the Japanese patent application (No. 2005-14448) including the specification, claims, drawings, and abstract filed on January 21, 2005 is referred to Incorporated here.
