BACKGROUND OF THE INVENTION
The present invention relates to a karaoke apparatus, and in particular, to an improvement in a lyrics display method during karaoke performance.
[0002]
[Prior art]
The karaoke apparatus plays a karaoke song and displays a lyrics telop on the screen in synchronization with the performance. In general, a karaoke song has a plurality of chorus (No. 1, No. 2, No. 3, etc.) singing sections, and sings different lyrics while repeating the same melody. Therefore, the lyrics telop also displays different lyrics for each chorus so as to guide this song.
[0003]
On the other hand, in the case of a karaoke song composed of a plurality of choruses as described above, it is also true that there is a desire to sing number 2 before number 1 and a desire to sing number 1 (or number 2) twice. There has also been proposed a karaoke apparatus for such a singer that displays the lyrics data by changing the order of the lyrics data (for example, Patent Document 1).
[0004]
[Patent Literature]
JP-A-9-330090 [0005]
[Problems to be solved by the invention]
In general karaoke songs, No.1, No.2, No.3, etc. are not evenly arranged. For example, there is a prelude before the No.1 chorus, and an interlude after the No.2 chorus. There is a singing ending (climax) and a follower after the third chorus.
[0006]
However, in the karaoke apparatus described in the above patent document, the lyrics data is simply divided into the first lyrics data, the second lyrics data, and the third lyrics data, and the order is changed. It was difficult to accurately match the data display timing with the performance data singing timing. Further, it is difficult to determine the position of the chorus lyrics of No. 1, No. 2, No. 3,... Only from the performance data and the lyrics data.
[0007]
An object of the present invention is to provide a karaoke apparatus capable of displaying the chorus lyrics of a plurality of chorus karaoke songs arbitrarily and accurately and according to the performance of the karaoke tunes.
[0008]
[Means for Solving the Problems]
According to the present invention, there is provided a performance data track for generating musical sounds, a lyrics data track for displaying lyrics telop, and mark data indicating chorus breaks such as singing No. 1, No. 2, No. 3, etc. The non-volatile storage means storing the song data having the written mark data track, and the tune data are read from the non-volatile storage means to the temporary storage means when playing the karaoke song, and the read song data is A karaoke apparatus having performance means for performing a performance operation by sequentially reading based on a tempo clock,
When the performance means reads the song data from the non-volatile storage means to the temporary storage means, the performance means cuts out the lyrics data of each chorus section of the lyrics data track based on the mark data, and puts it at each chorus position of the temporary storage means. The extracted lyric data of an arbitrary chorus number is inserted and read.
[0009]
<Action>
The karaoke apparatus according to the present invention includes choruses for singing No. 1, No. 2, No. 3, etc. in addition to a performance data track for generating musical sounds of karaoke songs and a lyrics data track for displaying lyrics telop. Music data having a mark data track in which mark data indicating a delimiter is written is stored.
[0010]
By arranging the mark data track in parallel with the performance data track and the lyric data track in this way, the chorus No. 1, No. 2, No. 3, etc. are singing sections on the lyric data track. This makes it easy to identify the lyric data.
[0011]
Also, in the present invention, lyrics data of chorus sections such as No. 1, No. 2, No. 3,... Are cut out based on the mark data, and lyrics data of an arbitrary chorus is inserted into each chorus number section of the temporary storage means. . Thereby, lyrics of an arbitrary chorus can be displayed in each chorus number section. Also, since the lyrics data of the singing section can be accurately cut out based on the mark data and can be accurately inserted, the performance and the lyrics display are not shifted even when the lyrics data of another chorus number is inserted.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram of a karaoke apparatus according to an embodiment of the present invention. In this karaoke device, a karaoke song is played based on the song data, and a lyrics telop is displayed on the monitor 22. In normal karaoke performance, the lyrics of No. 1, No. 2, No. 3, etc. are displayed in order according to the progress of the song, but when the lyrics replacement mode is set, for example, Lyric telops can be displayed in a free order (repeatedly) different from the chorus order of the performance, such as repeated display during the performance of No. 3.
[0013]
Song data for playing karaoke songs is stored in the hard disk 12. In addition to the song data storage area 121 for storing song data, the hard disk 12 is set with a program storage area 120 for storing various programs executed by the CPU 10 and a video data storage area 122 for storing video data for background video. ing.
[0014]
The CPU 10 executes a performance program 100 that controls the performance of karaoke music. The performance program 100 includes a music sequencer 101, a lyrics sequencer 102, a background video control program 103, and the like. The performance program 100 controls the karaoke song selection by inputting the song number, and executes a process of reading the song data of the selected karaoke song from the hard disk 12 to the RAM 11. The music sequencer 101 reads out the performance data track data of the music data read out to the RAM 11 according to the tempo clock, and executes a process of inputting the read performance data (event data) into the sound source 13. The lyrics sequencer 102 reads the lyrics data track of the song data read to the RAM 11 in accordance with the tempo clock, and executes a process of synthesizing the lyrics telop based on the read data (lyric display data). The background video control program 103 is a program for controlling reading of the background video displayed in parallel with the performance of the karaoke song, and is suitable from a plurality of video data compressed in the MPEG format stored in the hard disk 12. Is input to the MPEG decoder 16.
[0015]
The performance program 100 is read from the hard disk 12 to the RAM 11 when the karaoke apparatus is activated, and is executed by the CPU 10. In the RAM 11, a program reading area 110 from which the performance program 100 and the like are read, a music data reading area 111 from which music data of the karaoke music to be played are read, and the like are set. This music data reading area 111 corresponds to the temporary storage means of the present invention.
[0016]
The sound source 13 generates musical sounds of karaoke songs based on the event data input from the song sequencer 101. The generated musical sound is input to the control amplifier 14. A singing voice signal is also input from the microphone 20 to the control amplifier 14. The control amplifier 20 mixes the singing voice signal and the musical sound of the karaoke song and outputs it from the speaker 21.
[0017]
The display control unit 15 superimposes the image signal of the lyrics telop input from the lyrics sequencer 102 on the background video signal input from the MPEG decoder 16 and displays it on the monitor 22. The MPEG decoder 16 decodes the video data read from the hard disk 12 and converts it into an NTSC video signal.
[0018]
FIG. 2 is a diagram showing the composition of song data. The song data includes a performance data track, a lyrics data track, a mark data track, and the like. The performance data track is a track in which performance data of musical instruments of a plurality of parts is written. By inputting this data (event data) to the sound source 13, a musical sound is generated.
[0019]
The lyrics data track is a track in which lyrics display data (character code, display coordinates, display start timing, erase timing) for displaying lyrics is written in time series, and this data is also the same as the performance data track data. The tempo clock is read as the music progresses.
[0020]
The mark data track is a track in which mark data attached for each of various breaks in the karaoke song is written. As the mark data, a prelude start mark attached at a position where the prelude starts, a chorus 1 start mark attached at a position where the prelude ends and the first (chorus 1) starts, and the second (chorus 2) starts. The chorus 2 start mark attached to the position, the interlude start mark attached to the position where the interlude starts, the ending start mark attached to the position where the singing enters the ending, and the position where the singing ends and the ensemble starts There is an after-start mark. In this figure, the chorus 1 start mark to the chorus 2 start mark is number 1 (chorus 1), the chorus 2 start mark to the interlude start mark is number 2 (chorus 2), and the ending start is from the chorus 3 start mark. It can be seen that the space between the marks is number 3 (chorus 3).
[0021]
The song data includes other tracks and headers in which bibliographic data is written, but illustration and description of tracks and headers other than those described above are omitted for the sake of simplicity.
[0022]
In the song data storage area 121 of the hard disk 12, the data of each track is stored with the time axis matched as shown on the left side of FIG. When this song is requested in the normal mode, the CPU 10 reads this song data as it is into the song data reading area 111 of the RAM 11. On the other hand, when the request is made in the lyrics replacement mode, the performance data track and the mark data track are read as they are and transferred to the music data reading area 111 of the RAM 11. Is copied to the song data reading area 111 as it is, and then the lyrics data of the first, second, and third sections are cut out, and the cut out lyrics data are inserted into the positions designated by the singer to change the order of the lyrics. Change or display the same lyrics multiple times. At this time, the data (duration data) for designating the read timing (time) of the lyrics display data, which is each event data, is also shifted in accordance with the fitting position.
[0023]
Such replacement of the lyrics is performed when the music format of the chorus sections 1, 2, 3,... Is exactly the same, and the chorus 1, 2, 3,. This can be done easily by inserting the lyrics data of the section into the position of another chorus section. Also, if the music format of each chorus section is different, the contents are written as marks on the mark data track, and some of the lyrics in the chorus section are omitted or repeated, so that the format of the section to be inserted is changed. You just have to match.
[0024]
Even if the music formats of the chorus sections 1, 2, 3,... Are the same, the performance time may be slightly different due to changes in the performance of each chorus. In such a case, when the duration data is rewritten, the length of the lyrics data may be rewritten according to the length of the chorus section to be inserted.
[0025]
The operation of this karaoke apparatus will be described with reference to the flowchart of FIG.
[0026]
Here, in this flowchart, the music selection operation and performance preparation operation in the first mode will be described as an example of the lyrics replacement mode. The first mode is a mode in which the first lyrics are displayed in each of the first, second, third,.
[0027]
Karaoke song selection is performed by inputting a song number from a remote control device. The song number consists of a 6-digit number. If this song number is entered as it is, it is treated as a normal mode song selection, and if a 7-digit number string with 1 added to this song number is entered, this song number is entered. The input of the number is handled as the music selection in the first mode.
[0028]
In FIG. 3, when a song number is input (s1), it is checked whether a number is further added to this song number (six digits) (s2). If it is not added, the music data stored in the hard disk 12 is directly transferred to the music data reading area 111 of the RAM because the music is selected in the normal mode (s3). On the other hand, if a number is added (s2), it is determined whether the number is 1 (s4). If the added number is not 1, the process proceeds to another process designated by the added number. If the added number is 1, since the music selection is “No. 1 mode”, the music data corresponding to the No. 1 mode is read in s 5 (s 5).
[0029]
Here, the reading of the song data corresponding to the first mode is a reading in which the first lyric data is inserted into all chorus sections in the above-described lyrics replacement mode. That is, the performance data track and the mark data track are read as they are from the hard disk 12 to the song data reading area 111 of the RAM 11, and the lyrics data track is once read as it is into the song data reading area 111, and the first lyric data is read from there. Fit in the chorus section. As a result, when this song data is played, the performance of the karaoke song proceeds as No. 1, No. 2, No. 3, .., ending, but the display of the lyrics repeatedly displays the No. 1 lyrics.
[0030]
After this, proceed to the performance of karaoke songs. The performance of a karaoke song is performed by operating the tempo clock at the specified tempo, reading the event data specified at that timing as the tempo clock is counted up, and executing the process specified by the event data. It will be going. Since the lyrics data track of the song data has been rewritten by the above-described reading process, the lyrics can be displayed in the order set by the singer if the normal performance process is performed.
[0031]
In the above-described embodiment, 1 is added to the song number, and the song number with the added number is input to the karaoke device, thereby instructing the lyrics replacement mode. No hardware such as a key switch is required. However, the instruction method in the lyrics replacement mode is not limited to this.
[0032]
In the above flow chart, when the number 1 is added to the song number, the chord is played in a mode that repeats the number 1 lyrics in all choruses (number 1 mode). When n (= arbitrary numerical value) is added to, performance may be performed in a mode in which the nth lyrics are repeated in all choruses. In addition, by adding a plurality of numbers such as 223 after the song number, the chorus number lyrics to be displayed in order when the n (= 1, 2, 3,...) Number of the song is played. May be specified.
[0033]
【The invention's effect】
As described above, according to the present invention, a karaoke song composed of a plurality of choruses can cut out and replace the data of the lyrics data track for each chorus, so that the singer sings in the lyrics of his / her favorite order. Or, you can sing only the lyrics of your favorite chorus. In addition, since the lyrics are cut out and inserted based on the mark data track, the timing of the performance and the display of lyrics is not shifted.
