DESCRIPTION OF SYMBOLS 1 Music information reproduction apparatus 10 Reproduction | reorder change support unit 13 Music characteristic amount extraction part 14 Information storage part 15 Operation / display part 19 System control part

  Hereinafter, the best embodiment of the present application will be described with reference to the accompanying drawings. In addition, embodiment described below is embodiment when a reproduction | regeneration order change assistance unit is applied with respect to music information reproduction apparatuses, such as a car audio and a system audio, for example. FIG. 1 is a block diagram showing an example of the configuration of a music information playback apparatus incorporating the playback order change support unit of the present invention.

  As shown in FIG. 1, a music information playback apparatus 1 incorporating a playback order change support unit according to the present invention includes an information playback unit 11, an information output unit 12, a music feature amount extraction unit 13, an information storage unit 14, and an operation / display. Unit 15, microphone 16, voice recognition unit 17, communication unit 18 for performing data communication with the information distribution server 2 via the network 3, and a system control unit 19.

  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.) (An example of the presentation information of the present application) is reproduced, and the music is output to the information output unit 12, the music feature amount extraction unit 13, and the information storage unit 14.

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

In addition, the information reproducing unit 11 includes, on the recording medium, accompanying information accompanying the music (for example, the title and genre of the music (for example, rock, jazz, pop, classic, hip hop, etc.)).
Text information), artist name, age (for example, information indicating when it was produced), country of production, etc. (for example, when the recording medium is CD-TEXT, etc.) The playback unit 11 reads the accompanying information from the recording medium and outputs it to the information storage unit 14 under the control of the system control unit 19. Further, in the present embodiment, the accompanying information is handled as an example of feature information representing the feature of the music.

  Note that the configuration and function for reproducing music from a recording medium other than a CD are known techniques, and thus detailed description thereof is omitted. Further, a music piece may be played from a plurality of recording media like a multimedia player.

  Although not shown, the information output unit 12 inputs music (digital audio signal) reproduced by the information reproduction unit 11 or audio guide information output from the system control unit 19 and converts it into an analog audio signal. A DAC (Digital-to-Analog Converter), an AMP (Amplifier) that amplifies and outputs the analog 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. It is like that.

  The music feature quantity extraction unit 13 is configured by, for example, a DSP, inputs the music reproduced and output by the information reproduction unit 11, extracts the music feature quantity indicating the characteristics of the music from the music data, and receives information. The data is output to the storage 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 300) that quantitatively indicates the feature of the music, and is obtained from, for example, a musical tone of the music. Includes musical features. In the present embodiment, the music feature amount is also treated as an example of feature information representing the feature of the music.

  The musical feature values include keys (key tones in C major, A minor, etc.), key change positions (or change patterns), chords (Minor, Major), chord change positions (or change patterns), Chord change amount (CPM: Code Per Minute) (or rate of change (HVL)), beat (beat: constant pulse signal with strength), maximum value (or minimum value, average value) of the beat, Beat change position (or change pattern), beat change amount (BPM: Beat Per Minute, representing tempo) (or rate of change), maximum intensity or average intensity (average volume) of musical sound, volume change position (or Change pattern).

  Since various known methods can be applied to the extraction of these 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). ) To analyze the frequency and calculate the volume value for each frequency at a predetermined time interval along the time axis, and the key and the amount related thereto (key change position, etc.), the code and the amount related thereto (the code change position, etc. The amount of beat and the amount related to this (the maximum value of the beat (signal), etc.) are extracted by extracting the waveform or the like related to the music data at a predetermined threshold level.

  In this best mode, music feature information having the above-mentioned accompanying information, musical sound feature value (hereinafter referred to as music feature value), etc. is generated (generated) by the system control unit 19 and stored in the information storage unit 14, for example. Like to do. As for the music feature information, if the music information is information in the MP (MPEG Audio Layer) 3 format, for example, the title name, the rating of the music, the number of times of reproduction, etc. that the information has or is associated with, Data such as date and time of reproduction can also be extracted and added to the configuration.

  Such music feature information is used by the system control unit 19 to determine the tone of the music information. In the music tone discrimination process, for example, a music tone association table that prestores the information storage unit 14 or the like and defines the association between the music feature value and the music tone is used, and is performed based on the music feature value of the music. .

  Here, an example of the music tone association table will be described. For example, the music tone is classified into “bright music”, “sounding music”, “quiet music”, and “sad music”, and the music features are “key” and “chord change rate (HVL)”. ”,“ Beat variation (BPM) ”,“ maximum beat value ”, and“ average volume ”.

  Further, “high”, “medium”, and “low” indicating the level of the music feature amount are, for example, in the case of a beat change amount (BPM), “high” is a level (numerical value) range of 190 to 300, “Medium” is represented by a level range of 90 to 189, and “Low” is represented by a level range of 0 to 89 (thus, “Medium to High” represents a level range of 90 to 300, “Low”. "Medium" represents a level range from 0 to 189). For example, in the case of an average volume, “high” is a level range of 1.2 to 2, “medium” is a level range of 0.6 to 1.19, and “low” is a range of 0 to 0.00. Represented in 59 level ranges. Further, as an example of the “key”, “C major” or “B minor” can be indicated, and this is also expressed in a certain level 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 quantity of the identified music satisfies the music feature quantity level corresponding to “bright music” (in other words, For example, it is determined whether or not it falls within the numerical range), and if satisfied, the music is determined to match the “bright music” (the same applies to other music tones). Once the tune of the music is thus determined, information indicating the determined tune is registered in a music list described later in association with the music.

  In the present embodiment, it is assumed that the music tone is also treated as an example of music feature information representing the characteristics of the music.

  The information storage 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 the like. An HD drive or the like for recording music data or the like on the HD or reproducing from the HD is provided.

  Note that the information storage unit 14 may be configured to include a recording medium such as an MD, a DVD-RW, or a card-type recording medium.

  Then, under the control of the system control unit 19, the information storage unit 14 compresses, for example, the music data output from the information playback unit 11 and records the compressed data on the HD, and the accompanying data output from the information playback unit 11. The information is recorded on the HD in association with the music. Further, the information storage unit 14 is configured to record the music feature value output from the music feature value extraction unit 13 in association with the music under the control of the system control unit 19.

  Further, the information storage unit 14 is distributed from the information distribution server 2 via the network (for example, composed of the Internet, a mobile communication network, etc.) 4 and received via the communication unit 18 under the control of the system control unit 19. The recorded music data and accompanying information associated therewith are recorded on the HD.

  Note that the musical tone feature quantity of the music acquired from the information distribution server 2 is also extracted by the music feature quantity extraction unit 13 at the time of acquisition, for example, and recorded in association with the music.

  As described above, each piece of music information recorded on the HD in the information storage unit 14 is given a unique registration number (for example, a serial number), and is managed in a list. For example, the registration number of the music recorded on the HD, the data capacity, the recording location, the performance time, the accompanying information, the jacket image of the music (for example, the image of a single CD jacket), the title of the album and the jacket image (for example, And management information such as music feature quantities are registered 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.

  The accompanying information accompanying the music is input by the user by operating the operation / display unit 15 when the music data is recorded on the HD, and is registered in the music list as the management information. Also good.

In addition, the system control unit 19, for example, the TOC (Table of Table) recorded on the innermost periphery of the CD.
content) information, and using the TOC information as a key, a server (not shown) having a known CDDB (CD database) is inquired via the network 4, and the server accompanies the music recorded on the CD. Information and a jacket image (when the music is recorded on an album CD, an album jacket image) and the like may be acquired and registered as the management information in the music list.

  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 the user input various instructions. The operation buttons are displayed. When such an operation button is pressed, an instruction signal corresponding to the operation button is output to the system control unit 19. Further, a music icon as an example of a display object corresponding to each music is displayed on the display panel. When the music icon is pressed (touched), the music corresponding to the music icon is displayed. For example, an instruction signal indicating a reproduction instruction is output to the system control unit 19. A remote controller provided with the operation button may be used in combination.

  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 (for example, instruction information for selecting music) is recognized and output to the system control unit 19.

  The system control unit 19 includes a CPU having an arithmetic function, a working RAM, various processing programs (including an information processing program and a display control processing program), a ROM that stores data, and the like. It is an example of a display control apparatus. Note that the information processing program and the display control processing program may be downloaded from a predetermined server connected to the network 3, for example, or recorded on a recording medium such as a CD-ROM and stored in the recording medium. You may make it read via a drive.

  When the CPU executes a program stored in a ROM or the like, the system control unit 19 performs overall control of the music information reproducing apparatus 1 and performs music recording and reproduction control.

  Furthermore, the system control unit 19 selects music to be played from music registered in the music list (that is, a plurality of music recorded on the HD) based on a predetermined selection condition. The predetermined selection condition may be a preset condition or a condition instructed by the user. For example, when the user has instructed the condition “select 20 songs from rock or jazz”, the management information of each song registered in the song list is referred to and 20 songs corresponding to rock or jazz are stored. Will be selected. Alternatively, when the user gives an instruction of the condition “select all songs registered in the song list”, all the songs registered in the song list are selected.

  Then, when displaying the music list, the system control unit 19 reproduces the music information allocated under predetermined conditions such as the above-mentioned registration number order, the title name order of the music set by the user, and the artist order, for example. Set the playback order and display the music list in the playback order. Note that the playback order may be variously differently stored in the information storage unit 14 as playback order information, stored in association with music information, or generated and stored when the program is started.

  As the reproduction order information acquisition means in the claims, the system control unit 19 stores the reproduction order from the information storage section (reproduction order information storage means) 14 that stores the reproduction order information (or information corresponding thereto) indicating the reproduction order. Get information. And the music feature information which shows each characteristic of the said music information corresponding to the reproduction | regeneration order information which the said reproduction | regeneration order information acquisition means acquired as a music characteristic information generation means in a claim is generated. In addition, about generation | occurrence | production of this music feature information, when it memorize | stores beforehand in the information storage part 14, the music feature information linked | related with the music information corresponding to reproduction | regeneration order information is extracted from there, and it memorize | stores it. If not, the music feature information is generated as described above.

  Then, the system control unit 19 serves as the reproduction order feature information generation means in the claims based on the reproduction order information acquired by the reproduction order information acquisition means and the plurality of music feature information generated by the music feature information generation means. The reproduction order feature information for displaying the presentation information indicating the music information on the relation area indicating the relationship between the feature arbitrarily selected by the user and the reproduction order of the plurality of music information is generated.

  In the best mode, the system control unit 19 displays each of two pieces of feature information and reproduction order information arbitrarily set by the user in the X (horizontal) axis direction on the display screen of the operation / display unit 15. A music icon corresponding to the presentation information is formed at a position corresponding to each axis by allocating in the Y (vertical) axis direction orthogonal to the X-axis direction and the Z (depth) axis direction orthogonal to these. The reproduction order feature information for displaying is generated. Note that which information is allocated to which axis can be arbitrarily set by the user through the operation / display unit 15, for example.

  Then, the system control unit 19 instructs the operation / display unit 15 to display the reproduction order feature information as the display control means in the claims, whereby the reproduction order feature information is displayed on the operation / display unit 15. Display as. Based on the displayed position of the music icon on the displayed playback order feature screen, the user can visually grasp the relationship between the playback order and the music feature instantly.

  2A and 2B are diagrams showing examples of display of music icons corresponding to music on the playback order feature screen. FIG. 2A shows a case where the X axis is in playback order, and FIG. 2B shows a case where the Z axis is in playback order. Show.

  In the best mode, the case where the amount of beat change, the average volume, and the age are applied as the characteristics of the music in FIG. 2 will be described. For example, the amount of change in beat has a level of 1 to 300, and the average volume has a level of 1 to 2. In addition, for example, the era has levels from 1960, 1970, 1980, 1990, and 2000 (the era may be a level from the past (for example, the 1600s) and the interval between them. May also be every year (for example, 2002, 2003, 2004, etc.).

  In the reproduction order feature screen example shown in FIG. 2, five music icons 51 to 55 having different sizes are shown. On the music icons 51 to 55, for example, titles of the respective music (in the example of FIG. 3). , The title of the song (Track A, Track B,...) And an image of the jacket corresponding to each song are displayed on the song icon. For example, it may be displayed in advance.

  In the example of FIG. 2A, the X-axis direction represents the playback order, the Y-axis direction represents the BPM (beat variation) level, and the Z-axis direction represents the age of the music. The music icon 53 of a music with a large (high) volume level is positioned on the upper side in the Y-axis direction. Further, although not shown, the background screen excluding a plurality of music icon portions is displayed in a color, pattern, or picture corresponding to the above-described overall characteristic information that represents the characteristics of the entire music.

  The sizes of the music icons 51 to 55 each represent the level of the era, and the music icons are smaller in size as the music is older (for example, the 1950s) (in terms of image, paper space). As it goes in the depth (Z-axis) direction, it becomes an old age (for example, 1950s).

  In the example of FIG. 2B, the X-axis direction represents the average volume, the Y-axis direction represents the BPM level, and the Z-axis direction represents the playback order. FIG. 2B shows the case where only the above-described four music icons 51 to 54 are displayed, but the number of icons varies depending on the display target. In FIG. 2 (b), the music located at the upper right is a song with good momentum (eg, dance music), while the music located at the lower left is a gentle and quiet song (eg, ballad, etc.). Is).

  The sizes of the music icons 51 to 54 indicate the playback order. The slower the playback order, the smaller the music icon size (in terms of image, in the direction of the depth (Z axis) of the page). The playback order becomes slower as you go.)

  When the music icon displayed in this way is designated (touched), the system control unit 19 performs, for example, a music playback process corresponding to the music icon, but when the number of music selected increases, A plurality of music icons displayed on the display screen are displayed in an overlapping manner.

  As other display examples of the reproduction order feature screen, the music icons 51 to 54 are displayed in a display color corresponding to the feature of the music, and each icon is displayed in a different display color. can do. Further, in the best mode, a case of displaying as a three-dimensional reproduction order feature screen will be described, but a two-dimensional reproduction order feature screen by one feature and reproduction order may be used.

  Next, an example of the playback order change support process according to the present invention executed by the system control unit 19 having the above-described configuration will be described. FIG. 3 is a flowchart showing the reproduction order change support process executed by the system control unit of FIG.
