DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a karaoke system including a karaoke apparatus according to the present embodiment. The center server 10 distributes karaoke data and the like to the plurality of karaoke apparatuses 20 having a scoring function via the network 30. The center server 10 includes a database 11 and stores information related to scoring results collected from each karaoke apparatus 20.
[0007]
Next, information stored in the database 11 will be described. FIG. 2 is a diagram showing the contents of information stored in the database 11. As shown in this figure, the database 11 stores a distribution table of scoring results of karaoke songs for each song code of karaoke data distributed by the center server 10 for each gender. The stored contents of the database 11 are updated each time a scoring result is collected from the karaoke apparatus 20 as will be described later.
[0008]
Next, the configuration of the karaoke apparatus 20 will be described with reference to FIG. In this figure, the CPU 210 controls each part of the apparatus connected via the bus 211. The ROM 212 stores a control program executed by the CPU 210, and the RAM 214 is used as a work area of the CPU 210. A HDD (hard disk drive) 216 serving as a storage means stores a plurality of pieces of karaoke data for performing karaoke performance and a plurality of video data.
Here, the karaoke data is distributed from the center server 10 via the network 30, and the karaoke data for one song is further composed of music data, lyrics data, and scoring reference data. Among them, the music data defines the musical sounds that should be generated in accordance with the progress of performance and the control contents thereof in time series, and the lyric data is the character pattern (lyrics) to be displayed in accordance with the progress of performance and the character pattern The color change and the like are defined in a time series, and the scoring standard data defines the main melody of a song, that is, the frequency and volume of the melody to be sung in a time series in order to be used as a reference when scoring a song.
Also, the video data is compressed in, for example, MPEG format, shared for a plurality of karaoke songs, or one-to-one correspondence for each karaoke song.
The operation unit 218 has a plurality of operation keys such as character keys and numeric keys, and outputs a signal indicating the contents operated by the user to the CPU 210. This operation content is, for example, a song code of a karaoke song to be played designated by the user.
[0009]
On the other hand, the microphone 220 inputs the voice of the singer and supplies the voice signal to the mixer 222 and the A / D converter 224, respectively. The sound source 226 generates a musical sound signal based on the music data supplied from the CPU 210 and supplies this to the mixer 222. The mixer 222 synthesizes the audio signal input from the microphone 220 and the musical sound signal generated by the sound source 226. The synthesized signal is amplified by an amplifier or the like (not shown) or given an appropriate effect, and then output from the speaker 228.
[0010]
The A / D converter 224 converts the analog audio signal input from the microphone 220 into a digital signal. The voice processing unit 230 first determines the gender of the singer from the voice signal converted into the digital signal, and secondly, the frequency and volume (amplitude) of the voice signal converted into the digital signal are played. Each deviation amount is calculated by comparing with the frequency and volume of the scoring reference data corresponding to the music, and thirdly, the determined gender information and the calculated deviation amount are supplied to the CPU 210, respectively.
In addition, as for the discrimination method of the gender of a singer, for example, if the audio frequency at a predetermined performance point is relatively high (or if it is equal to or higher than a threshold value), it is determined that the woman is female, and if it is relatively low It is determined that he is male (or smaller than the threshold). In this embodiment, since the scoring target is the pitch and volume, the frequency and volume of the audio signal are compared with the scoring reference data. However, an element such as rhythm may be appropriately added and compared. good.
[0011]
The character reproduction unit 240 generates a character pattern according to the lyrics data supplied as the performance progresses, changes the color of the character pattern, and supplies the character pattern to the display control unit 242.
The video playback unit 244 decodes the video data supplied from the CPU 210 and supplies the decoded signal to the display control unit 242.
The display control unit 242 synthesizes the character pattern supplied from the character reproduction unit 240 with the video based on the decoded signal from the video reproduction unit 244, and also displays a screen created by the CPU 210 in a format that can be displayed by the monitor 246 (for example, NTSC) image signal, and the image signal is supplied to the monitor 246. The monitor 246 displays an image based on the image signal from the display control unit 242. The network I / F 250 is for connecting to the network 30.
[0012]
Next, operation | movement of the karaoke apparatus 20 which consists of the said structure is demonstrated. First, when a user selects a song to be sung and inputs the song code using the operation unit 218, a signal indicating the entered song code is transferred to the CPU 210. Then, the CPU 210 reads karaoke data corresponding to the song code from the HDD 216 and loads the former karaoke data into the RAM 214 once.
Thereafter, the CPU 210 instructs the start of karaoke performance. Specifically, the CPU 210 transfers the music data to the sound source 226, the lyrics data to the character reproduction unit 240, and the scoring reference data to the voice processing unit 230 of the loaded karaoke data in accordance with the progress of the karaoke performance. . As a result, the sound source 226 generates and controls musical sounds according to the music data, while the character reproduction unit 240 generates and changes the color of the character pattern in synchronization with the progress of performance due to the generation of musical sounds.
In parallel with the transfer of the karaoke data, the CPU 210 reads out video data corresponding to the song code input by the user from the HDD 216 and supplies the video data to the video playback unit 244. The video playback unit 244 stores the video data. Decode it. For this reason, the lyrics are displayed / color-changed on the monitor 246 in synchronization with the progress of the performance, and an image corresponding to the song is displayed in the background.
[0013]
On the other hand, the singer's voice signal from the microphone 220 is converted into a digital signal by the A / D converter 224 and supplied to the voice processing unit 230. The audio processing unit 230 determines the gender of the singer from the audio signal converted into a digital signal, supplies the gender information to the CPU 210, and the CPU 210 stores the gender information in the RAM 214. The audio processing unit 230 also extracts the frequency and volume from the audio signal converted into a digital signal, and compares it with the frequency and volume included in the scoring reference data supplied from the CPU 210 in synchronization with the progress of the performance. The deviation amount is calculated and returned to the CPU 210. The sound processing unit 230 repeatedly executes such a deviation amount calculation at regular intervals (for example, every 150 milliseconds) from the start to the end of the performance.
The CPU 210 accumulates the returned deviation amount and stores it in the RAM 214. Then, when all the music data is transferred to the final part, that is, when the karaoke performance is completed, the CPU 210 calculates a score so that the score becomes higher as the accumulated value is smaller, and the score information is stored in the RAM 214. When the karaoke performance is finished, the display of the lyrics and the background video on the monitor 246 is also finished.
Further, the CPU 210 receives the score information, the gender information of the singer, the song code indicating the performance song, and the ID information for identifying the own karaoke device 20 through the network I / F 250 and the network 30 as a center server. 10 to send.
[0014]
When the center server 10 receives the score information, the sex information, the song code, and the ID information, the center server 10 accesses the database 11 and is the gender indicated by the sex information in the frequency distribution table corresponding to the song code. The frequency corresponding to the score information is incremented by “1”. For example, if the received song code is “1000-01”, the gender indicated by the gender information is “male”, and the score indicated by the score information is “8 points” out of 10 points, 2, “53” indicating the frequency is updated to “54”.
As described above, in the database 11, when one karaoke device 20 among the devices connected to the network 30 finishes playing a certain song, the score obtained by the scoring is included in the frequency distribution indicating the totaling of the scores of the song. And items corresponding to the gender of the singer will be updated sequentially.
[0015]
Next, the center server 10 calculates the parameter of the frequency distribution after the update, and calculates the same-sex ranking of the score information. For example, if the content shown in FIG. 2 is updated, the parameter is calculated as “1050” and the rank is calculated as “58”.
Then, the center server 10 returns the calculated parameter information and rank information to the karaoke apparatus 20 specified by the received ID information.
[0016]
When the karaoke apparatus 20 specified by the ID information receives the parameter information and the rank information from the center server 10 via the network I / F 250, the CPU 210 reads the score information and the sex information stored in the RAM 214. In addition to these pieces of information, based on the received parameter information and sequential information, for example, screen information as shown in FIG. 4 is created and supplied to the display control unit 242.
Since the display control unit 242 converts the screen information into an image signal and supplies it to the monitor 246, the monitor 246 displays a screen as shown in FIG.
Therefore, according to the karaoke apparatus 20 of this embodiment, even if a man sings a song of a female vocal, for example, how much skill of the singing is within the group of men who sang the song in the past You can know what level it was.
[0017]
In the above-described embodiment, the frequency distribution scored for each song is classified according to male and female. However, the present invention can be grouped according to gender and various groups.
For example, it is good also as a structure classified according to the area where the karaoke apparatus 20 is installed. In the karaoke apparatus 20, when transmitting score information, ID information for identifying itself is also transmitted, so the center server 10 creates a table indicating the correspondence between the pre-segmented area and the ID information. On the other hand, if the ID information is received, the score information can be classified for each area by referring to the table and determining the installation area of the karaoke apparatus.
If the karaoke shop owns a plurality of karaoke apparatuses 20, the same configuration can be used to subdivide each karaoke shop, karaoke shop floor or theme, and so on.
In addition, for example, groups can be classified by genre such as pops, enka, anime, etc., and various types such as age (age), student, member of society, housewives are assumed.
[0018]
Further, the operation unit 218 may be used to cause the singer to select one or more groups that have been classified in advance, and the score ranking may be displayed among the selected groups.
Further, the ranks in a plurality of groups may be displayed in order or in a list.
