That is, when the karaoke application 112 streams and provides the sound source data 10 and the lyrics data 40 from the server, the server determines the lyrics display method, receives the decision value, and applies it at the unit of the smartphone terminal It is also possible.

Hereinafter, the configuration of the karaoke device 100 performing the lyrics display method according to this embodiment will be described in more detail with reference to FIG. 5.

Referring to FIG. 5, the karaoke device 100 according to the present embodiment includes a sound source playback unit 120, a progress speed determination unit 130, an image display unit 140, a lyrics display method determination unit 150, and a user input unit ( 160), a control unit 170.

The sound source playback unit 120 outputs the song selected by the user, that is, the sound source data 10 through the speaker device 300. Specifically, when the user inputs a specific song number, the sound source playback unit 120 may read the sound source data 10 stored in the database 105 through the input song number and output it through the speaker device 300. .

In addition, when a user inputs an attribute related to reproduction of the sound source data 10, the reproduction attribute is changed accordingly so that the speaker device 300 can output it.

As an attribute, for example, when the user skips the deliberation and inputs playing from the part where the lyrics appear, the section is skipped through the pre-stored deemed section information so that it can be played. Alternatively, when receiving information that speeds up or slows down the reproduction speed of the sound source data 10, or receives information that changes the pitch, etc., it is adjusted accordingly so that the sound source data 10 can be output.

The progress speed determining unit 130 receives metadata 20 for determining the progress speed of the sound source data 10 for karaoke accompaniment, and determines the progress speed using the metadata 20.

The progress speed is information indicating the speed of the sound source data 10 and may be stored in the meta data 20 as tempo information. That is, the progress speed determining unit 130 reads the tempo information from the metadata 20 and determines the progress speed through this. The speed of the progress may be determined as it is with the tempo information value, or may be calculated using an additional metadata value along with the tempo information value.

Referring to FIG. 6, FIG. 6 is a diagram illustrating meta data 20 of the sound source data 10 according to the present embodiment, wherein the meta data 20 includes song name information 21, song number information 22, Singer information 23, composer information 24, lyricist information 25, genre information 26, country information 27, and tempo information 28 may be included.

That is, in addition to directly extracting the tempo value stored in the tempo information 28 and determining it as the song progressing speed, the value of the additional metadata 20 can be used to determine the song progressing speed.

For example, in addition to the tempo information value of the sound source data 10, through the singer information 23, the tone or flow of the singer of the song is reflected to reflect the tone or flow, and the speed of the song according to the characteristics of the singer in addition to the tempo, more Specifically, the reading speed of the lyrics can be calculated. In addition, the singer information 23 may include information about whether the song is collaborated with other singers, and through this, for example, when a singer is collaborated with a ballad singer or a hip-hop singer who raps, the singer progresses by reflecting this. It is also possible to determine the speed.

Specifically, when a collaboration is performed with a singer, the speed of the song can be determined by dividing each singer. Therefore, the lyrics display method can also be determined for each singer.

In addition to the singer information 23, the composer information 24 and the songwriter information 25 can also affect the reading speed of the lyrics in addition to the simple tempo information, so that the song progress rate can be reflected.

In addition, through the genre information 26, the average song flow can be determined according to whether the genre of the song is ballad, hip-hop, or R & B, and reflected in the progress rate determination.

The country information 27 is information about the nationality of the singer, so the language used may vary depending on the nationality, and if the language is different, the method of displaying the text may vary. It can be used as additional information for.

In addition, lyrics data (or metadata of lyrics data) 40 may be used in addition to metadata 20 of the sound source data 10.

This will be described in more detail with reference to FIG. 7.

Referring to FIG. 7, the lyrics data 40 includes song matching information 42, sync information 44, language information 46, and data size information 48.

The song matching information 42 is information matching the karaoke song selected by the user, and when the karaoke device 100 stores the lyrics data 40 independently of the sound source data 10, the music source data 10 and the music selection data according to the user's selection. Together, the lyrics data 40 can be output through the display device 200.

Also, when the lyrics data 40 is included in the metadata 20 of the sound source data 10, song matching information may be omitted.

The sync information 44 is a timing value at which the lyrics data 40 should be displayed, and stores the progress time value of the song corresponding to each lyrics word, so that the lyrics data 40 is displayed at the corresponding progress time of the song.

That is, the sync information 44 synchronizes the sound source data 10 output through the speaker device 300 and the lyrics data 40 output through the display device 200, so that a user sings a song and easily recognizes the lyrics Make it possible.

Furthermore, the sync information 44 may store the progress time value of a song for each syllable included in the lyrics data 40 as more detailed information, and thereby additionally provide beat information through karaoke lyrics. In addition, the song sung by the user may be input from the microphone device 400, and the accuracy of the song sung by the user may be calculated through the sync information 44 as a score.

The language information 46 is a value for a language used in the lyrics data 40. For example, in the case of a Korean song, the language information may include Korean and English. Language information 46 used in the lyrics data 40 may be included according to songs of each country, such as English in the case of pop songs, Japanese in the case of J-POP, and the like.

At this time, the language information 46 may be used as additional information for determining the lyrics display method together with the country information 27 of the metadata 20 described above. For example, in the case of English, since there is no final consonant, the length of the word having the same meaning may increase, so it is possible to determine the lyrics display method by reflecting this.

The next data size 48 is an absolute size value of the lyrics data 40, and it is also possible to indirectly calculate a song progressing speed using this. That is, it is also possible to use the total length information of the song and the size of the entire lyrics data 40 as a numerical data size value to determine the speed of the song.

For example, if the size of the lyrics data 40 is 100 kb and the actual song progress time is 120 seconds excluding the total time of the song, 0.83 kb of text should be displayed per second, so this can be determined as an indirect song progress rate.

In addition, using the calculated song progressing speed, the lyrics display method determining unit 150 is the language information 46 that is displayed at one time in the video frame based on the data size of the text displayed per line in the video frame of the language. The number of lines of the lyrics data 40 can be determined.

Hereinafter, the lyrics display method determining unit 150 will be described in more detail.

The lyrics display method determination unit 150 determines a display method of the lyrics data 40 corresponding to the sound source data 10. The lyrics display method determining unit 150 is based on the one frame of the display device 200 screen where the lyrics data 40 is displayed according to the progress rate of the song determined by the above-described progress rate determining unit 130. ).

Specifically, the lyrics display method determining unit 150 may determine the number of display lines of the lyrics data 40 displayed per frame of the screen.

As illustrated in FIG. 1, the number of display lines of the lyrics data 40 may be determined based on the change in the song progress rate and the size of the lyrics data 40 based on the lyrics data 40 displayed in two lines.

For example, the progress speed of the song determined by the progress speed determination unit 130 may correspond to a predetermined section for each progress speed to select the number of corresponding display lines. Accordingly, the progressing speed determining unit 130 may divide the progressing speed of the song into sections and store the number of display lines corresponding thereto as a table.

In addition, it is also possible to store the changed values according to the language information of the lyrics data 40 described above as a reference table and reflect it, thereby determining the number of final display lines.

In addition, it is also possible to determine the number of final display lines arithmetically through the data size information of the lyrics data 40 described above in addition to the progress speed and language information.

Additionally, since the lyrics display method determination unit 150 determines the display method of the lyrics displayed on the image, it is also possible to determine the display method by reflecting information on the image that is the background of the lyrics.

At this time, the number of display lines may be determined by reflecting the display position of the lyrics and the size of the display space using predetermined information about the image, and more specifically, the image data (or meta data of the image data) 30 may be used. It is also possible to determine the display method.

Referring to FIG. 8, FIG. 8 is a diagram showing meta data 30 of image data, which includes song matching information 32, frame information 34, image object information 36, and other attribute information for image data (38).

The song matching information 32 is indexing information for matching the video data 30 and the sound source data 10 to a song, and similarly to the lyrics data 40, if the user selects the corresponding song, the video data 30 corresponding thereto is selected. It can be used to display.

For example, if a user selects a song of a specific singer, the lyrics data 40 and the music video of the song can be selected using the song matching information to be displayed on the display device 200.

The frame information 34 may include information such as the size of a frame in an image and the total number of frames in the image. You can calculate the total number of frames in the video and set the lyrics to be changed in a specific frame. Furthermore, if the size of the frame in the image is small to accommodate the determined number of lyrics display lines, it is possible to reduce the number of lyrics display lines by reflecting this.

The object information 36 in the image is information for storing objects included in the image, and may include, for example, information about a person or object appearing in the image, and background information appearing in the image. Since the object information 36 in the image is displayed as a background of the lyrics data 40 displayed in the foreground due to the characteristics of the karaoke device 100, it may affect visibility of the lyrics.

In addition, if an image displayed as a background is uncovered unconditionally by lyrics, it may be necessary to consider this complementarily because it may degrade the immersion or atmosphere provided by the image.

Accordingly, the lyrics display method determining unit 150 may determine the appropriate number of lyrics display lines in consideration of whether the visibility is affected by using the object information 36 in the image.

Referring to FIG. 9 and FIG. 10, FIG. 9 is a diagram showing an image in which a meaningful object in an image is included and FIG. 10 is an image in which an object having a slightly weaker meaning is included.

In the case of FIG. 9, two meaningful objects 230 are displayed on the screen 210, and the objects of the present invention are achieved within an unobstructed range when these objects provide the overall atmosphere of the song. The maximum number of lyrics display lines to be determined may be determined and displayed 220.

On the other hand, in the case of a simple background without a meaningful object on the screen 20 as shown in FIG. 10, even if the lyrics are displayed on the entire screen, there is no significant effect on immersion or mood, so the number of lyrics display lines is determined and displayed (220) )can do.

As described above, in the present embodiment, the lyrics display method determining unit 150 may determine the lyrics display method using the object information 36 in the image as meta data for the image data 30. It is also possible to reflect information such as the resolution of an image as other attribute information 38.

In this embodiment, the image display unit 140 causes the display unit 108 to output the image data 30 and the lyrics data 40 together according to the lyrics display method determined according to the operation of each of the above components.

In the present embodiment, the user input unit 160 receives information such as a change in the playback situation, such as a change in the playback speed of the user or skipping the consideration, based on the user's song selection information for the karaoke device 100. By reflecting it, the lyrics display method determining unit 150 may additionally check whether the lyrics display method needs to be changed.

In this embodiment, the control unit 170 controls the operation of each component according to the above configuration and delivers the collected information or the determined information to achieve the object of the present invention.

Furthermore, in this embodiment, the lyrics display method determining unit 150 may determine a method of changing the displayed lyrics as an additional function.

That is, when the number of display lines is determined by the lyrics display method determining unit 150 in accordance with the present embodiment, if the lyrics displayed in multiple numbers are simply changed, the user's gaze reads the lyrics of the bottom line and displays the changed screen. As the lyrics on the top line have to be read, disturbances due to movement of gaze may occur in singing.

Therefore, in this embodiment, after the number of display lines is determined, the lyrics display method determining unit 150 may further determine a method of changing the lyrics screen according to the number of display lines.

Referring to FIG. 11, the lyrics display method determining unit 150 according to the present embodiment may determine a method of changing the lyrics screen based on the middle value 2 of the number of display lines.

That is, according to FIG. 11, when lyrics are displayed in a total of four lines, the melody corresponding to the lyrics (③) of the line 3 may end based on the lyrics (②) of the line 2 and the lyrics (③) of the line 3, which are intermediate values. At some point, you can move the lyrics of each line to the top.

Therefore, the lyrics (①) existing in line 1 disappear from the screen, and the lyrics (②) existing in line 2 move to line 1, and the lyrics (③, ④) existing in line 3 and line 4 also correspond to line 2, respectively. And go to line 3. In line 4, lyrics corresponding to the next lyrics are displayed as new.

Therefore, the user can sing along the song while fixing most of the gazes at the positions of the lines 2 and 3.

Referring to FIG. 12, FIG. 12 shows a case in which lyrics are displayed in a total of five lines.

In this case, the lyrics can be changed in the manner described above based on the lyrics (③) of the line 3 corresponding to the median value (3), and the user recognizes the lyrics being changed while fixing most eyes on the line 3 Sing along.

However, since the progress rate of the song is faster than the average when displayed as a plurality of lines as shown in FIG. 12, if the entire lyrics are changed in the same manner as in FIG. 11 based on the lyrics of the line 3, the change becomes too frequent and the user Rather, it may become difficult to recognize lyrics.

Therefore, when the number of display lines is determined in excess of the number of specific lines, when the number of display lines is determined by five lines as shown in FIG. 12, the lines 2 and 4 of the lines before and after the line 3 (③) corresponding to the intermediate value The lyrics can be changed based on the lyrics (②, ④).

For example, when the melody corresponding to the middle part of the lyrics (④) of the line 4 is played, the lyrics (④) of the line 4 are moved to the position of the line 2, and the lyrics (⑤) of the line 5 is moved to the line 3. Can be. Also, the lyrics of line 3 (③) can be moved to line 1.

In the lines 4 and 5 of the changed screen, lyrics corresponding to the next melody may be newly displayed.

As described above, in the lyrics display method according to the present embodiment, the number of display lines of the lyrics is determined in consideration of the speed of the song, the properties of the lyrics data 40 and the properties of the image data 30. Accordingly, the method of displaying the next lyrics continuously is determined, and the lyrics are displayed in the most appropriate way for the user to sing along.

Furthermore, although the above-described embodiment was described based on the karaoke device 100, the karaoke device 100, as described with reference to FIG. 4, is a software karaoke application 112, a communication unit 102, and a memory unit ( 104), the speaker device 300 of the karaoke device 100 is a speaker unit 106 of a smartphone, the display device 200 is a display unit 108, and a microphone device (in hardware). 400) can be implemented as a microphone 110, so it can be applied as it is, with different subjects.

Hereinafter, the operation of the lyrics display method of the karaoke device 100 according to this embodiment will be sequentially described through a flowchart.

Referring to FIG. 13, the lyrics display method according to the present embodiment receives meta data for determining the speed of progress of the sound source data 10 for karaoke accompaniment (S100).

In the step of receiving input (S100), it is also possible to directly receive each meta data of meta data, lyrics data 40, and video data 30 that may directly receive tempo information as meta data or may be related to other speeds. It is possible.

When the meta data is input, the progress rate of the sound source data 10 is determined based on the metadata, and a display method of the lyrics data 40 corresponding to the sound source data 10 is determined (S200).

As described above, since the singer information, composer information, and lyrics information in addition to the tempo information may also affect the reading speed of the lyrics in addition to the simple tempo information, the speed of the song is calculated by reflecting this, and accordingly the display method of the lyrics data 40 is determined. Can decide.

Furthermore, it is also possible to determine the display method of the lyrics data 40 by reflecting the progress rate using language information and data size information as the lyrics data 40.

If the number of display lines is determined according to the above method, the sound source data 10 and the lyrics data 40 are output according to the determined display method (S300).

If the step of determining (S200) is described in more detail with reference to FIG. 14, the determining step may determine a display method of the lyrics data 40 based on one frame of a screen on which the lyrics data 40 is displayed. As a result, the number of display lines of the lyrics data 40 may be determined (S210).
