Description

  The present invention relates to an audio device and a music list sorting method and a music list sorting program of the same device, for example, according to a user's music selection from karaoke content provided by a music distribution service like an in-vehicle information communication system having a karaoke function The present invention relates to a technique suitable for use in an apparatus capable of playing music.

  Vehicle-mounted devices represented by car navigation systems have rapidly become multifunctional and highly functional with the development of information technology (IT) in recent years. For example, a car multiplayer called “G-BOOK” (registered trademark) Equipped with a mobile network communication function such as a system in which media and a network are integrated, various information services can be appropriately used even during driving. In recent years, such information services include a music distribution service, a karaoke content distribution service, etc., which are not recorded on a recording medium such as a built-in hard disk, CD, or DVD by operating an in-vehicle device. Even music (for example, the latest music) can be received via the network and played (reproduced) in the vehicle.

  When such a music or karaoke content distribution service (hereinafter collectively referred to as a music distribution service) is used by the user, the user usually prefers it on a display screen of an available music list distributed from a service center or the like. By performing the music selection operation, the music to be distributed is determined and received (downloaded) by the in-vehicle device via the network. Here, the music list is usually sorted according to a simple rule such as the order of the syllabary of the music title or singer name (or alphabetical order), and is also applied to the display screen of the in-vehicle device. The music list is displayed in the sort order.

In addition, as a prior art relevant to such a service, there exists a technique proposed by the postscript patent documents 1-5, for example.
Here, the technology (content search apparatus and method) of Patent Document 1 uses the classification tree used in the search and the order of presentation of the search results to determine the attributes of the user (gender, date, place of residence, genre of interest) An object of the present invention is to provide a directory-type content search apparatus and method that can be changed according to the current time. For this purpose, a rank value based on a user attribute and a current time with respect to a content search result. A rank value is assigned from the assignment rule, and the search result presentation order is changed based on the rank value (individual ranking) and returned to the user terminal. As a result, a content search can be performed using a directory that matches the user's preference and purpose, and desired content can be easily reached.

  In addition, the technique (broadcasting center) of Patent Document 2 aims to automatically aggregate request information from viewers without bothering human hands, and to promptly present the aggregation results to the viewers. Therefore, the request information from the viewer is stored as request logging data in combination with the reception time information, and each time a request is received, the top 10 songs with the highest number of requests at that time are stored as real-time rankings. Broadcasting is performed so that the number of requests and the song title are displayed.

Furthermore, the technology of Patent Document 3 relates to a music playback device that can be used as both a karaoke device and a BGM performance device. When not used as a karaoke device, when used as a BGM performance device, by genre, age, or singer The purpose is to allow only songs that meet the user's desires, such as different ones, to be played without using a dedicated playback medium such as a laser disc or video tape. Therefore, in the technique of Patent Document 3, the user is allowed to specify what genre, age or singer's song is to be played, thereby searching for a song corresponding to the specified genre, age or singer. Thus, the corresponding music is automatically and sequentially played as BGM (lyric data is not read from the hard disk). As a result, it is possible to automatically perform a large number of pieces of music that meet the user's preference as BGM without using a dedicated reproduction medium for BGM performance.

  The technique (broadcasting center) of Patent Document 4 aims to broadcast a program program in which karaoke songs are played in order of the number of requests. For that purpose, a request log from a request log within a predetermined time is used. Create a table sorted in descending order, determine the genre (enka, pop, anime, etc.) of the program to be created, and assign the request codes in descending order of the number of requests from those corresponding to the determined genre code. When the program time is filled, the program configuration data is stored in the external storage device. If the program time is not filled, the music of the same genre is randomly extracted from the request database and added to the number configuration data until it is filled. It has become. Thereby, it is possible to automatically create and broadcast a program program for playing karaoke songs in order of the number of requests. Accordingly, it is possible to automatically broadcast the viewer's daily changing preferences without intervention of the operator.

Furthermore, the technique of Patent Document 5 relates to EMD (Electronic Music Distribution) that distributes content including music data using the Internet or the like, and aims to enable distribution of music content that satisfies user preferences. Yes. For this reason, in the technique of Patent Document 5, user header information is added from the terminal device to the variable header area of the music content, stored in the database, and the attribute information is calculated by the information management device so as to reflect the user's preference. In addition, music contents are distributed based on newly added attributes. This makes it possible to distribute music content that satisfies the user's preference without providing a dedicated server that stores the music content that reflects the user's preference.

In the present embodiment, at least the “genre” of the music selected by the user in karaoke or the like [ Japanese pops (J-POP), rock, R & B (Rhythm and Blues), etc.] and "ages" (70s, 80s, 90s, etc.) are given rankings (points), "genre" and "age" A function that calculates a total point of the number and creates a ranking management table and sorts (sorts) a music list (hereinafter also referred to as an audio list) based on the ranking management table (total points) (music list sorting function) have.

Therefore, the control unit 25 according to the present embodiment focuses on the main part in terms of software, for example, as shown in FIG. 2, a reproduction detection unit 250, a category information acquisition unit 251, a ranking point calculation unit 252, a ranking management unit, and the like. 253, a music list control unit 254, a sort valid / invalid setting unit 255, and a display control unit 256.
Here, the reproduction detection unit 250 detects that a song selected (or downloaded) by a user from a certain song list is reproduced, for example, by detecting a reproduction operation by the user, and the category information acquisition unit When the reproduction detection unit 250 detects reproduction of the music piece 251, information relating to at least “genre” and “age” of the music piece is acquired as category information. A karaoke data category information acquisition unit 251a for acquiring the category information from karaoke song book data or karaoke content data including category information related to a plurality of song data corresponding to the song list stored in the karaoke data storage unit 222; The category is acquired by the karaoke data category information acquisition unit 251a. Server (center) connection unit 251b that connects to the content server 1 that manages data corresponding to the storage contents of the storage unit 222 via the network 3 and acquires the category information from the server 1 when the information cannot be acquired. Is provided.

“Karaoke song book data” refers to, for example, a plurality of songs used in general karaoke stores or the like for user song search (selection), by genre or age, or in alphabetical order, alphabetical order. This means data corresponding to the contents of song books classified and ordered, and “karaoke content data” is displayed on the display of the user terminal for music search (selection) in online karaoke services and the like. The data corresponding to the content of the above-mentioned song book may be received by the audio device 2 via the network 3 or may be set and stored in advance in the audio device 2 and obtained. The destination is unquestioned. The data structure is not particularly required as long as it includes at least the category information.

For example, FIG. 3 shows an example of the data structure of music distributed from the content server 1 (or obtained from a CD or the like on which distributed music is recorded) in the present embodiment. As shown in FIG. 3, the music data is composed of a header part (Content Data Header) 30 and an appropriate number of data files (data element: Element # 1) connected to the header part 30 in accordance with the number of music pieces. , # 2, # 3, # 4) 31, for example, the data file 31 connected immediately after the header part 30 is used as an index file (see FIG. 4), and the above category information is stored in the index file 31. Various data including it can be set. Therefore, in this case, the category information acquisition unit 251 extracts and acquires the category information from the index file 31.

  However, in addition to the above “genre” and “age”, the category information acquisition unit 251 includes “tempo” (up tempo, medium tempo, slow tempo, etc.), “atmosphere” [bright (fun), dark (Sad) etc.], information on a part or all of “singer”, “lyricist” and “composer” can be additionally and selectively acquired as category information. Of course, information on other categories other than these can be used as appropriate. In this case, a part or all of these “tempo”, “atmosphere”, “singer”, “lyricist”, and “composer” are set according to the user setting by the ranking point calculation target control unit 254a described later. Thus, it is possible to control whether to be effective (ON) / invalid (OFF) control, that is, whether the ranking point value calculation unit 252 is to calculate or exclude the ranking point value.

Next, the ranking point calculation unit 252 calculates the total points of the ranking point values according to the appearance frequency (ratio) of each category information acquired by the category information acquisition unit 251. Here, in this embodiment, the “ranking point value” is a value obtained by multiplying the rate at which category information of a song appears by selecting a song by 100 [for example, 90's (40%) × 100 = 40 points], and the “total points” is a value obtained by adding the ranking point values of each category information [for example, J-POP (2
0 points) + 90s (40 points) = 60 points].

The ranking management unit 253 manages the ranking of the total point values obtained by the ranking point calculation unit 252. In this embodiment, for example, a ranking management table 221 as shown in FIG. 5 is created. Yes. In the ranking management table 221 shown in FIG. 5, “genre” (J-POP, ballad, rock) is used as category information.
And the ranking is set in descending order of the total point value for all combinations of ranking point values of “age” (80s, 90s, 00 (2000)) (1st place: J-POP & 90s, 2nd place) : J-POP & 00s, 3rd place: J-POP & 80s).

  The ranking management table 221 is updated by providing the playback detection unit 250 as described above, not when the user selects music, but when the selected music is actually played (playback started). Will be. This is because at the time of music selection, it can still be canceled. The ranking management table 221 can also be managed for different users (for each user ID) of the audio device 2 by receiving user identification information (ID) through the input unit 24.

  The music list control unit 254 sorts the music list stored in the music list storage unit 223 by the music list sorting unit 254b based on the ranking management table 221 managed by the ranking management unit 253. is there. Note that the music list storage unit 223 is one or both of a music list received from the music distribution service content (content server 1) via the network 3 and a music list such as karaoke that can be provided by the own device 2. Is memorized. That is, the audio apparatus 2 can set both the music list received from the content server 1 and the music list previously held by the own apparatus 2 as the sort target.

  Further, as described above, the music list control unit 254 includes the ranking point calculation target control unit 254a, so that the “tempo”, “atmosphere”, “singer”, “lyricist”, and “composer” of the music are provided. It is possible to control whether or not a part or all of each category information related to the selection is selectively included in the ranking point calculation unit 252 or excluded (ON / OFF) according to the user setting. .

  Further, the sort valid / invalid setting unit 255 selectively sets the music list sort (ranking management table function) by the music list control unit 254 to be valid or invalid (ON / OFF) according to the setting by the user. Thus, it is possible to select whether the music list is sorted and displayed on the basis of the ranking management table 221 or is displayed in a normal order such as 50-sound order or alphabetical order.

Specifically, the user setting for the ranking point calculation target control unit 254a and the sort valid / invalid setting unit 255 is performed by the user on a “setting screen” 233 displayed on the display unit 23, for example, as shown in FIG. This is realized through the input unit 24 by setting ON / OFF.
The display control unit 256 controls the screen display of the display unit 23 so that the setting screen, the music distribution content, the music list before or after sorting by the music list control unit 254, and the like are displayed on the display unit 23. It has become.

  Note that the above-described functions as the control unit 25 (all or a part of the functions of the respective units 250 to 256) are realized by a computer such as a CPU executing a predetermined application program (music list sort program of the audio device). The The program is provided in a form recorded on a computer-readable recording medium such as a flexible disk, a CD-ROM, a CD-R, a CD-RW, an MO, and a DVD. In this case, the computer reads the program from the recording medium, transfers it to the storage unit 22 (which may be an external storage device), stores it, and uses it. It is also possible to record the program in a storage device (recording medium) such as a magnetic disk, an optical disk, or a magneto-optical disk, and provide the program to the computer via a communication line.

  Here, the computer is a concept including hardware and an OS (operating system) and means hardware that operates under the control of the OS. Further, when the OS is unnecessary and the hardware is operated by the application program alone, the hardware itself corresponds to the computer. Furthermore, the hardware includes at least a microprocessor such as a CPU and means for reading a program recorded on a recording medium.

The application program includes program code for causing the computer as described above to realize the function as the control unit 25. Some of the functions may be realized by the OS instead of the application program.
Further, the karaoke data storage unit 222 and the music list storage unit 223 may be realized by dividing the storage area of the storage unit 22 shown in FIG. 1, or in an image as shown in FIG. All or a part thereof can be realized by a dedicated storage device.

Hereinafter, the operation of the audio apparatus 2 of the present embodiment configured as described above (the music list sorting method of the audio apparatus) will be described in detail with reference to FIGS.
First, for example, as schematically shown in FIG. 7, a music purchase screen is displayed when the user presses a “purchase screen” button on the top screen 231 of the music distribution content displayed on the display unit 23 of the audio apparatus 2. Is selected, a purchase screen 232 having a “setting” button 232a, a “song name” button 232b, a “singer name” button 232c, a “user list” button 232d, and the like is displayed on the display unit 23.

  Here, for example, when the “setting” button 232 a is selected, a setting screen 233 at the upper right of the page in FIG. 7 is displayed on the display unit 23. As described above with reference to FIG. 6, the setting screen 233 includes “ranking management table function”, “tempo” (up, medium, etc.), “atmosphere” (bright, sad, etc.), “singer”, “lyricist”, Buttons for setting ON / OFF of these category information are arranged for each “composer”, and the user appropriately enables or disables all or part of these category information as necessary. It is possible to set. However, the category information of “genre” and “age” is indispensable information, and cannot be set here (button non-display or non-selectable state display).

On the other hand, when the user selects a piece of music that the user wants to purchase on the purchase screen 232, the selection is performed using the “song name” button 232b, the “singer name” button 232c, and the “user list” button 232d.
That is, for example, when searching from a song name, by selecting the “song name” button 232b, a 50-sound song selection screen 235 is displayed on the display unit 23, and the user searches for the desired song name on the screen 235. . The search result is displayed as a song name search result screen 236, and the target song is determined on the screen 236.

On the other hand, when searching from the singer name, by selecting the “singer name” button 232c, for example, the 50-singer singer selection screen 237 is displayed on the display unit 23. Search for a singer's name. Similarly, the search result is displayed as a singer name search result screen 238, and the target music is determined on the screen 238.
Further, when searching from an original user list, a “user list” button 232d is selected to display a user list screen 234 shown at the lower right of the page of FIG. Here, the “user list” is, for example, a music list sorted based on the ranking management table 221. In FIG. 7, all the songs of “J-POP & 90s” are listed in the order of 50 tones. A state [AAA (music name) / BBB (singer name), etc.] is shown. The user list screen 234 also includes a “song name” button 234a, a “singer name” button 234b, a “scroll” button 234c, and a “ranking” button 234d. If the “song name” button 234a is selected, The list can be sorted by song name, and if the “singer name” button 234b is selected, the list can be sorted by singer name. Further, the currently displayed music list can be scrolled as appropriate by the “scroll” button 234c, and the ranking (“J-POP & 90s”, etc.) to be displayed can be sequentially changed by the “ranking” button 234d. ing.

Next, a procedure for creating the ranking management table 221 will be described with reference to FIGS.
First, as shown in FIG. 8, it is assumed that the user purchases (downloads) a certain karaoke piece from the music distribution content and reproduces it as described above (step S1). Then, the reproduction detection unit 250 of the control unit 25 detects the reproduction, and the category information acquisition unit 251 is activated using this as a trigger. The category information acquisition unit 251 first accesses the karaoke data storage unit 222 and determines whether category information can be acquired from the stored content (karaoke song book data or karaoke content data) (step S2).

As a result, if acquisition is possible, the category information acquisition unit 251 acquires each category information including at least “genre” and “age” from the karaoke data storage unit 222 by the karaoke data category information acquisition unit 251a (step S2). Step S3) from the YES route.
On the other hand, if acquisition is impossible, the category information acquisition unit 251 makes an inquiry about information (category information) about the reproduced music to the content server 1 by the center connection unit 251b (NO in step S2). Necessary category information is acquired via the network 3 from the music information database (DB) 11 of the content server 1 that holds at least information corresponding to the stored contents of the karaoke data storage unit 222 from the route (step S4). .

When the category information is acquired in this way, next, the ranking point calculation unit 252 and the ranking management unit 253 are activated, and the ranking management table 221 is created based on each acquired category information (step S6). .
For example, as shown in FIG. 9A, 120 songs have already been selected (reproduced) by the user, and among them, ranking point values are ranked points for each category information of “genre”, “age”, “tempo”, and “atmosphere”. As a result of calculation (aggregation) by the calculation unit 252, “J-POP” music is 50P (“P” means point) by “genre” (= 60/120 music × 1
00), “Rock” songs are 40P (48/120 songs × 100), “R & B” songs are 10P (= 12/120 songs × 100), and “90s” songs by “age” 68P (= 81/120 songs × 100), “80s” songs are 32P (= 39/120 songs × 100), and “UP (tempo)” songs are 80P (96) by “tempo”. / 120 songs × 100), “SLOW (tempo)” songs are 20P (= 24/120 songs × 100), and “bright” songs are 70P (84/120 songs × 100) by “atmosphere”, “ If the “dark” song is 30P (= 36/120 songs × 100), the ranking point calculation unit 252 further sums all patterns (combinations) (3 × 2 × 2 × 2 = 24) of each category information. Calculate points and determine ranking The In the example of FIG. 9A, the first place is “J-POP &90's& UP & Dark” song with a total of 268P, and the second place is “Rock &90's& UP &” with a total of 258P.
The ranking is such as “bright” music, and this content is stored in the storage unit 22 as a ranking management table 221.

  If the music newly selected / reproduced by the user in step S1 is “Rock & 80's & SLOW & Dark”, after the category information acquisition unit 251 acquires the category information as described above, The ranking point calculation unit 252 recalculates the ranking point value of each category information. That is, as shown in FIG. 9B, the total number of songs is updated to 121 songs, and the ranking point value obtained by multiplying the ratio to the total number of songs (121 songs) by 100 is recalculated for each category information. The total points are recalculated and the ranking management table 221 is updated. In FIG. 9B, the updated total point value is changed, but the ranking itself is not changed.

On the setting screen 233 described above with reference to FIGS. 6 and 7, for example, when the user is set to OFF for the “atmosphere” category information, as shown by the shaded portion in FIG. The ranking point value related to the category information is masked (excluded from the total point value calculation target) by the ranking point calculation target control unit 254a, and the ranking management table 221 is updated. In this case, the first place is 197P with "J-POP & 9
The song of “0's & UP” and the second place are 187P, “Rock &90's& UP”.

If the same total point value exists, the ranking management unit 253 determines the rank in alphabetical order of “genre”, for example. Further, when the “genre” is also the same, the other category information (“age”, “tempo”) is sequentially used to determine the rank.
As described above, the ranking management unit 253 creates (updates) the ranking management table 221 and manages the ranking of the total point value of each category information. Then, the music list control unit 254 sorts the music list based on the ranking of the ranking management table 221 (step S7 in FIG. 8).

For example, as shown in FIG. 10, in the ranking management table 221, the first ranking of the total points is the song “J-POP & 90s”, the second is the song “J-POP & 00s”, and the third is “J-POP & 80s” The song list control unit 254 first sorts the “J-POP &90's” songs ranked first in the order of 50 notes (double sorting), and then ranks “ The songs of “J-POP & 80s” are sorted in the order of 50 notes, and thereafter, the song list is similarly sorted in the order of the notes in the ranking order of the ranking management table 221 and displayed on the display unit 23.

  As described above, according to the present embodiment, the ranking point value corresponding to the appearance frequency is assigned to each category information including at least “genre” and “age” using the music selection information of the music (karaoke) by the user. And a ranking management table 221 is created from the total point value, and a predetermined music list is sorted based on the ranking management table 221. Therefore, various types of information provided on hard disk audio, music distribution content, karaoke song selection pages, etc. Can be displayed (listed up) in the order according to the user's preference and music selection tendency. Therefore, it does not take extra time for the user to search for the target music.

In addition, since the ranking management table 221 is updated every time the user selects music (reproduction of music), the ranking management table 221 can be updated according to the user whose preference is easily changed. The optimal music list sorting can be realized.
In addition to “genre” and “age”, category information includes additional information such as “tempo”, “atmosphere”, “singer”, “lyricist”, “composer”, etc. By using this, ranking management with higher accuracy can be realized. The user's intention can be reflected in the ranking management table 221 (music list order) by enabling ON / OFF setting of the category information by the user.

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