Alternatively, the karaoke application 112 may directly receive the display method of the lyric data 40 from the server, apply the received lyric data 40 to the received lyric data 40, and display the result on the display unit 108. That is, when the karaoke application 112 streams and provides the sound source data 10 and the lyric data 40 from the server, the server determines the lyric display mode and receives the determination value and applies it in units of the smartphone terminal It is also possible.

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

5, the karaoke system 100 according to the present embodiment includes a sound source playback unit 120, a speed determination unit 130, a video display unit 140, a lyrics display mode determination unit 150, a user input unit 160, and a control unit 170.

The sound source playback unit 120 outputs a 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 reads the sound source data 10 stored in advance in the database 105 through the inputted song selection number, and outputs the sound source data 10 through the speaker device 300 .

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

As an attribute, for example, when the user skips the reference and inputs the reproduction from the portion where the lyrics are displayed, the section can be skipped through the previously stored reference information. Receiving information for increasing or decreasing the reproduction speed of the tone generator data 10, receiving information for changing the tone pitch, or the like, the tone generator 10 can be controlled so that the tone generator data 10 can be output.

The progress rate determining unit 130 receives the 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 can be stored in the meta data 20 as the tempo information. In other words, the progress speed determination unit 130 reads the tempo information from the metadata 20 and determines the progress speed thereof. The speed of progress can be determined as the tempo information value as it is, or it can be calculated using the additional metadata value with the tempo information value.

6 illustrates the metadata 20 of the sound source data 10 according to the present embodiment. The metadata 20 includes music name information 21, song number information 22, Song information 24, lyric information 25, genre information 26, country information 27, and tempo information 28. In addition,

That is, the tempo value stored in the tempo information 28 can be directly extracted and determined as the song progress speed, and the value of the additional metadata 20 can be used to determine the song progress speed.

For example, in addition to the tempo information value of the sound source data 10, the tone information and the flow rate are reflected in the manner of singing the singers of the song through the song information 23, In detail, the reading speed of the lyrics can be calculated. In addition, the artist information 23 may include information on whether or not a song collaborates with other singers. For example, a singer may reflect a ballad singer or a rap artist performing a collaboration with a hip- It is also possible to determine the speed.

Specifically, when collaboration with the singer is performed, the speed of the song can be determined by dividing the song by each singer. Therefore, the lyric display system can be determined by the singers.

In addition to the song information 23, the composer information 24 and the lyric information 25 may also affect the lyric reading speed in addition to the simple tempo information.

In addition, the genre information 26 can be used to grasp the average song flow according to whether the genre of the song is ballad, hip-hop or R &

The country information 27 is information on the nationality of the singer, and the language to be used may vary depending on the nationality. If the language is different, the notation system of the text may be changed. Therefore, Can be used as additional information.

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

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

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

When the karaoke system 100 stores the karaoke data 40 independently of the music source data 10 as the karaoke song selected by the user and the matching information, the music matching information 42 stores the karaoke data 10 So that the lyric data 40 can be output through the display device 200.

In addition, if the lyric data 40 is included in the metadata 20 of the tone generator data 10, the song matching information may be omitted.

The sync information 44 may store a progress time value of a song corresponding to each lyric word as a timing value at which the lyric data 40 should be displayed and display the lyric data 40 at the corresponding progress time of the song.

That is, the sync information 44 synchronizes the sound source data 10 outputted through the speaker device 300 and the lyric data 40 outputted through the display device 200 so that the user can easily sing .

Further, the sync information 44 may store the progress time value of the syllable-included song included in the lyric data 40 as more detailed information, thereby enabling to additionally provide beat information through the karaoke lyrics. In addition, a song called by the user is input from the microphone device 400, and the accuracy of the song called by the user through the sync information 44 can be calculated as a score.

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

At this time, the language information 46 may be used as additional information for determining the lyric display mode together with the country information 27 of the metadata 20 described above. For example, in the case of English, since the length of a word having the same meaning in the image may increase due to lack of support, the display method of the lyrics can be determined by reflecting the same.

The next data size 48 is an absolute size value of the lyric data 40, and it is also possible to indirectly calculate the song progress speed using this value. That is, it is also possible to use the total length information of the song and the size of the total lyrics data 40 as the numerical data size value for determining the progress 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 except for the total time of the song, the text should be displayed at 0.83 kb per second, so that the indirect song progress rate can be determined.

Also, using the calculated song progress speed, the lyric display mode determination unit 150 displays the lyric display mode determination unit 150 at once in the image frame based on the data size of the text displayed per line in the image frame of the language as the language information 46 The number of lines of the lyric data 40 can be determined.

Hereinafter, the lyric display style determination unit 150 will be described in more detail.

The lyric display mode determination unit 150 determines a display mode of the lyric data 40 corresponding to the sound source data 10. The lyrics display method determination unit 150 reads the lyrics data 40 based on one frame of the screen of the display device 200 on which the lyrics data 40 is displayed according to the progress speed of the song determined by the above- ) Is determined.

Specifically, the lyric display mode determination unit 150 can determine the number of display lines of the lyric data 40 displayed per frame of the screen.

The number of display lines of the lyric data 40 can be determined on the basis of the change of the song progress speed and the size of the lyric data 40 on the basis of the lyric data 40 indicated by two lines as shown in Fig.

For example, the progress speed of the song determined by the progress speed determining unit 130 may be associated with a predetermined section of the progress speed, and the number of corresponding display lines may be selected. Accordingly, the progress speed determining unit 130 may divide the progress speed of the song into sections and store the number of display lines corresponding thereto in a table.

It is also possible to store the change values according to the language information and the like of the lyric data 40 described above in the reference table and to reflect the change values to determine the number of the final display lines.

It is also possible to determine the number of final display lines more arithmetically through the data size information of the lyric data 40 in addition to the progress speed and the language information.

In addition, since the lyric display mode determination unit 150 determines the display mode of the lyrics displayed on the image, it is also possible to determine the display mode by reflecting the information about the image as the background of the lyrics.

At this time, the number of display lines can be determined by reflecting the display position of the lyrics and the size of the display space using the predetermined information on the image, more specifically, by using the image data (or the metadata of the image data) It is also possible to determine the display mode.

8 is a block diagram showing the metadata 30 of the video data. FIG. 8 is a block diagram of the video data 30 including the song matching information 32 for the video data, the frame information 34, the object information 36 in the video, (38).

The song matching information 32 is indexing information for matching the image data 30 and the sound source data 10 with a song and is similar to the lyric data 40. When the user selects the song, Lt; / RTI >

For example, when the user selects a song of a specific artist, the artist can select the lyrics data 40 and the music video of the song using the song matching information, and display the song data on the display device 200.

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

The in-video object information 36 is information for storing the objects included in the image, for example, information about a person or object appearing in the image, and background information appearing in the image. Since the in-vivo object information 36 is displayed in the background of the lyric data 40 displayed on the foreground due to the characteristics of the karaoke system 100, it can affect the visibility of the lyrics.

In addition, if the image displayed in the background is unconditionally blocked by the lyrics, it may reduce the immersion or the atmosphere provided by the image. Therefore, it is necessary to consider them complementarily.

Accordingly, the lyric display mode determination unit 150 can determine the number of appropriate display lines by considering the influence of the visibility by using the in-vivo object information 36.

9 and FIG. 10, FIG. 9 illustrates a case in which an object having a meaning in an image is included, and FIG. 10 illustrates an image including an object in which the meaning is somewhat weak.

In the case of FIG. 9, two objects 230 are displayed in the screen 210, and if the objects provide the overall atmosphere of the music, The maximum number of lyrics display lines to be displayed can 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 great influence on the immersion or the atmosphere. )can do.

As described above, in this embodiment, the lyric display method determining unit 150 can determine the lyric display method using the in-video object information 36 as the metadata for the video data 30. [ It is also possible to reflect information such as the resolution of the image as the other attribute information 38.

The video display unit 140 causes the display unit 108 to output the video data 30 and the lyric data 40 together according to the lyric display method determined according to the operations of the above-described configurations.

In the present embodiment, the user input unit 160 receives information such as a change in the playback speed of the user, a change in the playback status, such as skipping the reference, based on the song selection information of the user for the karaoke system 100 So that the lyric display mode determination unit 150 can additionally confirm whether it is necessary to change the lyric display mode.

In the present embodiment, the controller 170 controls the operation of each of the components according to the above configuration, and transmits collected information or determined information to achieve the object of the present invention.

Furthermore, in the present embodiment, the lyric display mode determination unit 150 can determine a method of changing the displayed lyric as an additional function.

That is, when the lyrics display method determination unit 150 determines a large number of display lines in accordance with the present embodiment, if a plurality of lyrics are simply changed, the user's gaze reads the lyrics of the bottom line, As the lyrics of the top line must be read, disturbance may occur due to the movement of the eyes in singing.

Therefore, in the present embodiment, after the number of display lines is determined, the lyric display style determination unit 150 can further determine the manner of changing the lyric screen according to the number of display lines.

Referring to FIG. 11, the lyric display method determining unit 150 may determine a method of changing the lyric screen based on the middle value (2) of the number of display lines.

11, when the lyrics are displayed on a total of four lines, the melody corresponding to the lyrics (3) of the line 3 ends on the basis of the lyrics (2) of the line 2 and the lyrics (3) of the line 3 By the time, you can move the lyrics of each line to the top.

Thus, the lyrics (①) that existed on line 1 disappear from the screen, the lyrics (②) existing on line 2 move to line 1, and the lyrics (③ and ④) And line 3, respectively. In line 4, the lyrics corresponding to the next lyrics will be newly displayed.

Therefore, the user can sing along the line while fixing most eyes to the positions of line 2 and line 3.

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

In this case, the lyrics can be changed in the above-described manner on the basis of the lyrics (3) of the line 3 corresponding to the intermediate value (3). The user can visually recognize the changed lyrics while fixing most of the eyes to the line 3 I can sing along.

However, in the case of displaying a plurality of lines as shown in FIG. 12, since the progress speed of the song is faster than the average, if the entire lyrics are changed in the same manner as in FIG. 11 based on the lyrics of the line 3, Can be rather difficult to recognize the lyrics.

Therefore, when the number of display lines exceeds the number of specific lines and the number of display lines is determined to be five lines as shown in FIG. 12, the number of display lines in the line 2 and line 4 The lyrics can be changed based on the lyrics (②, ④).

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

Lines 4 and 5 of the changed screen may be displayed with new lyrics corresponding to the next melody.

As described above, in the lyric display method according to the present embodiment, the number of display lines of the lyrics is determined in consideration of the progress speed of the song, the attribute of the lyric data 40, and the attribute of the image data 30, It then determines how to display the next lyric in succession and displays the lyric in the most appropriate way for the user to follow the song.
