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 in the case where a playback order change support unit is applied to a music information playback device such as a car audio or a system audio. 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 device 1 incorporating a playback order change support unit of the present invention includes an information playback unit 11, an information output unit 12, a music feature quantity extraction unit 13, an information storage unit 14, An operation / display unit 15, a microphone 16, 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 configured.

[0014] The information reproduction unit 11 is controlled by the system control unit 19 under the control of a 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) ) (An example of the presentation information of the present application) recorded in (), and the music is output to the information output unit 12, the music feature amount extraction unit 13, and the information storage unit 14.

[0015] 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 (not shown). An optical pickup that optically reads recorded information and 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, Performs predetermined demodulation processing and error correction processing, etc., converts the digital signal into a digital signal processing circuit (for example, a DSP (Digital Signal Processor)), spindle motor and optical pickup. A servo circuit or the like for controlling the voice is provided, and the music is played and output.

[0016] Further, the information reproducing unit 11 includes, on the recording medium, accompanying information accompanying the music (eg, text information such as the title and genre of the music (eg, rock, jazz, pop, classic, hip hop, etc.)), If the artist name, age (for example, information indicating when it was produced, etc.), country of production, etc. are recorded (for example, if the recording medium is CD-TEXT, etc.), the information playback unit 11 Under the control of the control unit 19, the associated information is read from the recording medium and output to the information storage unit 14. In the present embodiment, the accompanying information is treated as an example of feature information representing the feature of the music.

[0017] It should be noted that the recording medium power other than the CD is a known technology for the configuration and function for reproducing the music, and detailed description thereof will be omitted. Further, like a multimedia player, the music may be reproduced from a plurality of recording media.

[0018] 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 the like, and receives this as an analog audio signal DAC (Digita-to-Analog Converter) for converting to analog, AMP (Amplifier) for amplifying and outputting the analog audio signal, and a speaker for outputting the amplified analog audio signal as sound waves, etc. Is now output.

[0019] The music feature quantity extraction unit 13 is configured by, for example, a DSP or the like. The music feature quantity extraction unit 13 inputs the music reproduced and output by the information reproduction unit 11, and the music feature quantity indicating the characteristics of the music from the music data. Is extracted and output to the information storage unit 14 and the system control unit 19

[0020] Here, the music feature amount is information (for example, represented by a numerical value between 0 and 300) quantitatively indicating the feature of the music, and includes, for example, a musical tone of the music Musical sound features obtained from In the present embodiment, the music feature amount is also treated as an example of feature information indicating the music feature.

[0021] Musical feature values include key (musical tonality in C major, A minor, etc.), key change position (or change pattern), chord (Minor, Major), change position (or change pattern) of the chord. ), Change amount of the corresponding chord (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 , Change position (or change pattern) of the beat, change amount of the beat (BPM: Beat Per Minute, indicating tempo) (or rate of change), maximum intensity or average intensity (average volume), change in volume Position (or change pattern), etc.

[0022] Since various known methods can be applied to the extraction of the musical sound feature values, a detailed description thereof will be omitted. For example, the music feature value extraction unit 13 converts the music data into a high-speed Fourier transform. 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 to calculate the key and its related amount (key change position etc.), the code and its related amount ( By extracting the chord change position, change amount, etc.) or detecting the envelope of the waveform related to the song data at a predetermined threshold level (the maximum value of the beat (signal), etc.) ).

[0023] In this best mode, for example, the system control unit 19 generates (generates) music feature information having the above-mentioned accompanying information, musical sound feature value (hereinafter referred to as music feature value), etc., and the information storage unit 14 is remembered. For music feature information, if the music information is MP (MPEG Audio Layer) 3 format information, for example, the title name, song rating, number of plays, Data such as date and time of playback can 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 this music tone discrimination process, for example, a music tone association table preliminarily stored in the information storage unit 14 or the like that defines the correspondence between the music feature amount and the music tone is used, and is performed based on the music feature amount of the music. .

Here, an example of the music tone association table will be described. For example, tunes are classified as “bright tunes”, “smooth tunes”, “quiet tunes”, and “sad tunes”, and tune characteristics are “ki”, “chord change rate (HVL ) ”,“ Beat change (BPM) ”,“ Maximum beat ”, and“ Average volume ”.

[0026] Further, "high", "medium", and "low" indicating the level of the music feature amount are, for example, a beat change amount (BPM), and "high" is a level (numerical value) of 190 to 300. ) In the range, “medium” is 90-189 In the bell range, “low” is represented by a level range of 0 to 89, respectively (so “medium to high” represents a level range of 90 to 300, and “low to medium” represents a level range of 0 to 189. Represents a level range). For example, in the case of 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 Each is represented by a level range of 0.59. Further, as an example of the “key”, it is possible to indicate “No major” or “B minor”, which is also expressed in a certain level range, for example.

[0027] When the music tone discrimination process is performed with reference to such a music tone association table, for example, the music feature amount of the identified music satisfies the music feature amount level corresponding to "bright music". It is determined whether or not the power (in other words, whether it falls within the numerical range) is satisfied, and if it is 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.

[0028] 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.

[0029] The information storage unit 14 includes, for example, a buffer memory for temporarily storing music data, an encoder Z decoder for encoding (compressing, etc.) or decoding (decompression, etc.) music data, HD ( Hard Disc) and HD drive etc. for recording music data on HD or playing back from HD.

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.

[0031] 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 reproduction unit 11 and records the compressed data in HD, and the information reproduction unit 11 1 The associated information output from is recorded in the HD in association with the music. Further, the information storage unit 14 records the music feature quantity output from the music feature quantity extraction unit 13 in association with the music piece under the control of the system control unit 19! /

[0032] Further, the information storage unit 14 is distributed 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.) 4, and the communication unit 18 of the music received via 18 and accompanying information accompanying this Recorded on the HD.

[0033] Note that the musical tone feature value of the music acquired from the information distribution server 2 is also extracted by the music feature value extraction unit 13 at the time of acquisition, for example, and recorded in association with the music.

[0034] In this way, 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, data capacity, recording location, performance time, additional information, song jacket image (for example, single CD jacket image), album title and jacket image (for example, recorded on HD) And management information such as music feature quantities are registered in the song list. The music list data is recorded in HD, for example, and is appropriately read and used by the system control unit 19.

[0035] The accompanying information accompanying the music is input by the user operating the display unit 15 when the music data is recorded on the HD, and is registered in the music list as the management information. You may do it.

[0036] In addition, the system control unit 19 reads, for example, TOC (Table of content) information recorded in the innermost periphery of the CD, and uses the TOC information as a key to read a known CDDB (CD database). Sano (not shown) provided is inquired via the network 4, and the relevant information and jacket image of the music recorded on the CD from the server (if the music is recorded on the album CD) Jacket image) and the like may be acquired and registered in the music list as the management information.

[0037] 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! When such an operation button is pressed, an instruction signal corresponding to the operation button is output to the system control unit 19. Furthermore, a music icon as an example of a display object corresponding to each music is displayed on the display panel, and the music icon is pressed (touched).

) And an instruction signal indicating, for example, a reproduction instruction of the music corresponding to the music icon is output to the system control unit 19. A remote control provided with the operation button may be used in combination. For example, the microphone 16 detects (collects) sounds related to various instructions uttered by the user and outputs the sound signals to the sound recognition unit 17.

[0039] 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 group of speech speech candidates prepared in advance. Thus, information included in the audio signal (for example, instruction information for selecting a music piece) is recognized and output to the system control unit 19.

[0040] The system control unit 19 includes a CPU having a calculation function, a working RAM, various processing programs (including an information processing program and a display control processing program), a ROM for storing data, and the like. This is an example of the information processing apparatus and the display control apparatus. The information processing program and the display control processing program may be downloaded from a predetermined storage device connected to the network 3, for example, or recorded on a recording medium such as a CD-ROM. It may be read via the drive of the recording medium.

[0041] Then, by executing a program stored in the CPl ^ ¾OM or the like, the system control unit 19 performs overall control of the music information playback device 1 and performs music recording and playback control and the like. ing.

Furthermore, the system control unit 19 selects a music to be reproduced from music pieces 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, if the user instructs the condition “Select 20 songs from rock or jazz”, the management information of each song registered in the song list is referred to, and the music corresponding to rock or jazz is found. The song 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.

[0043] Then, when displaying the music list, the system control unit 19 uses, for example, the music allocated under predetermined conditions such as the above-described registration number order, the title name of the music set by the user, and the artist order. Set the playback order in which information is played back, and display the song list in that playback order. indicate. It should be noted that the playback order can be in various forms such as being stored as playback order information in the information storage unit 14, stored in association with music information, or generated and stored when the program is started.

[0044] The system control unit 19 is an information storage unit (playback order information storage unit) that stores playback order information (or information corresponding thereto) indicating the playback order as the playback order information acquisition unit in the claims. The reproduction order information is acquired from Then, as the music feature information generating means in the claims, the music feature information indicating the characteristics of the music information corresponding to the reproduction order information acquired by the reproduction order information acquiring means is generated. As for the generation of the music feature information, if it is stored in the information storage unit 14 in advance, the music feature information associated with the music information corresponding to the playback order information is extracted therefrom, In this case, the music feature information is generated as described above.

[0045] Then, the system control unit 19 serves as reproduction order feature information generation means in the claims, and includes reproduction order information acquired by the reproduction order information acquisition means and a plurality of music feature information generated by the music feature information generation means. Based on the reproduction order feature 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 Generate information.

[0046] In the best mode, the system control unit 19 displays each of the two feature information arbitrarily set by the user and the playback order information as X (horizontal) on the display screen of the operation / display unit 15. By allocating in the axial direction, the Y (vertical) axis direction orthogonal to the X-axis direction, and the Z (depth) axis direction orthogonal to these, the relationship area is formed, and the above-described regions are arranged at positions corresponding to the respective axes. The reproduction order feature information for displaying the music icon corresponding to the presentation information is generated. Note that which information is assigned to which axis can be arbitrarily set by the user through the operation / display unit 15, for example.

[0047] Then, the system control unit 19 instructs the operation / display unit 15 to replay the reproduction order feature information on the operation / display unit 15 by instructing the operation / display unit 15 to display the reproduction order feature information as display control means in the claims. It is displayed as a live order feature screen. Based on the display 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. [0048] FIG. 2 is a diagram showing a display example of the music icon corresponding to each music on the playback order feature screen. (A) is when the X axis is in playback order, and (b) is when the Z axis is in playback order. Each case is shown.

[0049] In the best mode, the case where the amount of beat change, average volume, and age are applied as the characteristics of the music in FIG. 2 will be described. For example, the amount of beat change ranges from 1 to 300, and the average volume ranges from 1 to 2. Also, for example, the era has a level power up to 1960, 1970, 1980, 1990, and 2000 (the era may be a level from the past (eg, 1600s). The interval is also every year (for example, ί, 2002, 2003, 2004, etc.).

[0050] In the playback 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, the titles of the respective music (FIG. 3). In the example, the song title (Track A, Track Β ·····) is displayed, and the jacket image corresponding to each song is displayed on the song icon. The image (for example, stored in advance) may be displayed.

[0051] In the example of Fig. 2 (a), 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. For example, the music icon 53 of a music with a high (high) average 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 overall characteristic information representing the characteristics of the entire music described above.

[0052] 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) (image). In particular, the older age (for example, the 1950's) as it moves in the depth direction (Z-axis).

In the example of FIG. 2 (b), 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. In FIG. 2 (b), the number of power icons indicating the case where only the four music icons 51 to 54 described above are displayed varies depending on the display target. In Fig. 2 (b), the music located in the upper right is a song with good momentum (for example, dance music), while the music located in the lower left is gentle. It is becoming a quiet song (such as a ballad).

[0054] The size of the music icons 51 to 54 indicates the playback order. The slower the playback order, the smaller the music icon size (in terms of image, the depth of the paper (Z-axis ) The playback order becomes slower toward the direction).

[0055] When the displayed music icon is specified (touched), the system control unit 19 performs, for example, the reproduction processing of the music corresponding to the music icon. Number of selected music When the number of songs increases, multiple music icons displayed on the display screen are displayed in layers.

[0056] As another display example of the playback order feature screen, the music icons 51 to 54 may not be displayed in a display color according to the music feature, or each icon may be displayed in a different display color. However, it can be in various forms. Further, in this best mode, it is possible to provide a two-dimensional reproduction order feature screen based on one feature and a reproduction order for explaining the case of displaying as a three-dimensional reproduction order feature screen.

Next, an example of the reproduction 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 playback order change support process executed by the system control unit of FIG.

In this best mode, a reproduction order change support processing program for causing the system control unit 19 to execute a reproduction order change support process is stored in the information storage unit 14, and this program is stored in the system. When executed by the control unit 19, the playback order information acquisition means, music feature information generation means, playback order feature information generation means, display control means, change information capture means, and playback order change means in the claims. The system controller 19 will function.

[0059] When the reproduction order change support processing program is executed by the system control unit 19 in response to a request from the user, etc., in step S11 (reproduction order information acquisition means) shown in FIG. The playback order information is acquired from 14 and stored in the working RAM, and then the process proceeds to step S12. As for the acquisition of the playback order information, the playback order information corresponding to the music information to be played back and the subsequent music information is acquired.

[0060] In step S12, the feature display condition is acquired from the information storage unit 14 or the like, and the work RA is performed. Is stored in M, and then proceeds to Step SI 3. The feature display condition is to set items (axis arrangement) preset by the user or the like for each axis on the playback order feature screen and a screen pattern such as the type of icon.

[0061] In step S13 (music feature information generating means), music feature information indicating each feature of the music information corresponding to the obtained reproduction order information is acquired from the information storage unit 14 and associated with the reproduction order information. Is stored in the working RAM, and then the process proceeds to step S14.

[0062] In step S14 (playback order feature information generating means), the features arbitrarily selected by the user based on the playback order information in the working RAM, the song feature information and the feature display conditions, and the plurality of songs Reproduction order characteristic information for displaying the music icon (presentation information) indicating the music information on the relation area indicating the relation with the reproduction order of the information is generated and stored in the working RAM, and then the process goes to step S15. move on.

[0063] In step S15 (display control means), the operation / display unit 15 is instructed to display the reproduction order feature information in the working RAM, and then the process proceeds to step S16. The operation / display unit 15 displays a playback order feature screen (see FIG. 2) based on the playback order feature information according to the display instruction. Note that, when displaying on a different terminal device, the terminal device is instructed to display the reproduction order feature information via the communication unit 18.

In step S 16, it is determined whether or not there is an input from the operation / display unit 15. If it is determined that there is no input (N in S16), this determination process is repeated to wait for input from the user. On the other hand, if it is determined that there is an external force input (Y in S16), the process proceeds to step S17.

[0065] In step S 17 (change information fetching means), based on the input from the operation / display unit 15, for example, changes to the playback order such as deletion of music, addition of music, movement of playback order, etc. The contents are extracted, taken as change information indicating the change contents, stored in the working RAM, and then the process proceeds to step S18. In addition, as a method for extracting the changes, the selection is detected based on the touch position of the touch panel of the operation / display unit 15 by the user, etc., but various changes are specified by selecting a predetermined position. The menu to be displayed can be displayed, and the selection contents for the menu can be detected.

[0066] In step S 18 (reproduction order changing means), based on the change information of the working RAM, The reproduction order information to be changed is specified and changed, and the change result is reflected in the reproduction order information stored in the information storage unit 14, and then the process proceeds to step S19.

[0067] In step S19, the playback order feature information displayed on the operation / display unit 15 is updated based on the changed playback order information. In step S20, the updated playback order feature information is updated. The update display is instructed to the operation / display unit 15, and then the processing is terminated. Then, in response to this display instruction, the operation / display unit 15 displays a playback order feature screen (see FIG. 2) changed by the user based on the playback order feature information.

[0068] It should be noted that the playback order changing process described above is terminated when a termination request is received from the user or the like after step S20, and if another modification is requested, step S16 and subsequent steps This process can be repeated, or the process can be terminated when reproduction of music information is requested.
