The present invention relates to a karaoke apparatus that displays a song title of a karaoke song on a monitor and makes it easy for a user to request by playing a part of the song.
[0002]
[Prior art]
Conventional karaoke equipment displays the names of frequently requested songs (best) and new songs on the monitor when there is no request and no karaoke songs are being played (during performance), making it easy for users to request I am doing so.
[0003]
[Problems to be solved by the invention]
However, the introduction of the best and new music is requested only by scrolling the name of the song and the name of the original singer on the monitor, and only the person who knows the song knows what kind of song it is. The effect of prompting was insufficient. Also, users who know the melody but do not know the title of the song have a drawback that this display alone does not help the request.
[0004]
An object of the present invention is to provide a karaoke apparatus that makes it easier to request by displaying a song name and simultaneously playing a part of the song or displaying the face of an original singer.
[0005]
[Means for Solving the Problems]
  The invention of claim 1 of this application isIt is identified by the song number, and includes multiple song name data and musical tone data.Storage means for accumulating and storing karaoke song data;Includes new song information data with song numbers of multiple new songs or best information data with song numbers of best songsInformation that stores multiple information datadataOne piece of information from the information file storage means between the storage means and the karaoke performance.dataSelect and read this informationEach song number in the dataSpecifyeachRead karaoke song data sequentially,Acquire a partial section of song name data and music data included in each karaoke song data, and use the acquired song name dataWhile displaying the song name,AcquiredAn introduction means for performing a part of the section is provided.Karaoke device.
[0006]
  The invention of claim 2 of this application provides the introduction means.Next, the performance of the partial section is executedIt is characterized by comprising selection means for selecting whether or not.

In the invention of claim 3 of this application, in the invention of claim 1, when the singer image storage means for storing the images of a plurality of singers and the introduction means displays the song title of the karaoke song data, the karaoke song data Singer search means for searching for a singer image corresponding to the singer image storage means, and composite display means for combining and displaying the singer image searched by the singer search means with the song name. And
[0008]
In the present invention, when the user does not request (when the karaoke performance is not performed), the song name such as the best 20 or new music is displayed to prompt the user's request. Then, when displaying the song name, a part of the song (for example, chorus) is played in parallel. Among the karaoke songs, the chorus part is the part that the user knows best, so the user can request more easily by listening to it. The invention of claim 3 makes it easy to remember the song by displaying the name of the song and displaying the face of the original singer of the karaoke song (singer singing on a commercial record of the song) at the same time as the partial performance. ing.
[0009]
On the other hand, the performance of a part of the karaoke music takes more time than only the display of the music title, so the performance is unnecessary for the user who wants to see only the information on the best and new music. Therefore, in the invention of claim 2, this can be turned on / off. This makes it possible to introduce an optimal song according to the user.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram of a karaoke apparatus according to an embodiment of the present invention. The CPU 10 that controls the operation of the entire apparatus includes a ROM 11, a RAM 12, an external interface 13, a hard disk storage device (HDD) 14, a communication control unit 15, a remote control receiving unit 16, a display panel 17, a panel switch 18, and a sound source via a bus. 19a, 19b, chorus processing units 20a, 20b, DSPs 21a, 21b, a character display unit 25 and a display control unit 26 are connected. A CDV player 28 and an LD changer 29 are connected to the external interface 13.
[0011]
As described above, this karaoke apparatus includes two performance units (system 0 and system 1) including the sound source 19, the chorus processing unit 20, and the DSP 21, and can perform a plurality of karaoke songs without interruption. Further, these two performance sections continuously play the chorus portion in parallel with the display when the information to be introduced by displaying the song name on the monitor 27 such as the best 20 information and new music information. That is, during normal karaoke performance, only one system is used to perform karaoke performance, but during medley performance or information on continuous performance of the chorus part, the system is switched for each song. This is because it takes about 10 seconds to read out the song data and set the sound source before playing the song, and this is executed behind the scenes (when playing the opposite system).
[0012]
A mixer 22 is connected to the DSPs 21 a and 21 b, and a D / A converter 23 is connected to the mixer 22. The audio output terminal of the D / A converter 23 is connected to an audio amplifier 31 which is an external device. A vocal microphone 30 and a speaker 32 are connected to the audio amplifier 31. An external monitor 27 is connected to the display control unit 26.
[0013]
The ROM 11 stores a sequence program for karaoke performance, an information screening program for information screening, and the like. The RAM 12 is provided with a reserved data reading area 12a for reading music data of a song reserved during karaoke performance from the HDD 14, and is played based on the information CM data reading area 12b for reading information data and the information CM data. Two lines (system 0: 12c-0, system 1: 12c-1) are set for the trial listening data reading area 12c for reading a part of the karaoke song (music data). These two sample listening data read areas 12c-0 and 12c-1 correspond to the performance system 0 (sound source 19a, chorus processing unit 20a, DSP 21a) and system 1 (sound source 19b, chorus processing unit 20b, DSP 21b), respectively. is doing. Note that the trial listening is different from normal karaoke performance, and only a part of the performance is performed, and the lyrics are not displayed. Therefore, the trial listening data reading area 12c may be smaller than the reserved data reading area 12a.
[0014]
The communication control unit 15 downloads music data for karaoke performance, information on new music, and information on the best 20 from the center and writes the data in the HDD 14. The communication control unit 15 has a built-in DMA circuit, and can directly download downloaded music data and information data to the HDD 14 without using the CPU 10. The HDD 14 is provided with a music data file 14a for accumulating and storing about 10,000 music data downloaded and an information data file 14b for storing information data.
[0015]
The remote control receiver 16 receives the infrared signal sent from the commander 3 and restores the data. The commander 3 includes various key switches such as a numeric keypad and a mode switching key. When the user operates these switches, the commander 3 transmits an infrared signal modulated with a code corresponding to the operation. The user can input a song number and a command to the karaoke apparatus main body by the on-sequence of the various key switches.
[0016]
The display panel 17 includes an LED display for displaying the input song number and the like. The panel switch 18 includes a key switch of the same type as the commander 3 in addition to the numeric keypad, and the song number can be input by operating the panel switch.
[0017]
Hereinafter, one of the two performance parts will be described. The sound source 19 forms a musical tone signal based on event data input from the CPU 10. The event data is data written in the performance track of the music data, and is data for controlling the sound generation / mute. The chorus processing unit 20 forms an audio signal such as a back chorus based on the audio data. The audio data is obtained by converting a signal waveform (such as a back chorus) that is difficult to generate electronically from the sound source 19 into ADPCM data from a raw audio signal, and the chorus processing unit 20 expands and pitch-converts this to output. The DSP 21 gives various effects to the musical sound signal input from the sound source 19 and the audio signal expanded by the chorus processing unit 20. The karaoke performance sound to which the effect is given is output to the mixer 22. Note that the types and degrees of effects provided by the DSPs 21a and 21b are controlled by DSP control data input from the CPU 10. The DSP control data is stored together with the delta time data in the DSP control track of the music data, and the CPU 10 reads it at a predetermined timing of the karaoke performance and inputs it to the DSP 21.
[0018]
The mixer 22 mixes the karaoke performance signals input from the DSPs 21 a and 21 b at an appropriate ratio and outputs the mixed signals to the D / A converter 23. The D / A converter 23 converts this karaoke performance signal into an audio signal, and then outputs it to an audio amplifier 31 externally attached to the karaoke apparatus body. The audio amplifier 31 mixes and amplifies the karaoke performance signal and the singing signal input from the microphone 30 at a predetermined ratio, and outputs the amplified signal to the speaker 32.
[0019]
Character display data for displaying a song title and lyrics when a karaoke song is played is input to the character display unit 25. The character display data is data written in the character display track of the music data, and the time interval data (in order to display the song name and lyrics in synchronization with the karaoke performance based on the musical tone track and to change the display color) Delta time data). The character display unit 25 generates a character pattern such as a song title or lyrics based on the character display data. Further, the LD changer 29 reproduces the image of the laser disk during karaoke performance. The CPU 10 determines what background video is to be reproduced based on the genre data of the karaoke song to be played, and transmits the chapter number of the background video to the LD changer 29 via the interface 13. The LD changer 29 selects and reproduces the chapter video designated by the CPU 10 from a plurality of (about 5) laser disks. The character pattern generated by the character display unit 25 and the background video reproduced by the LD changer 29 are input to the display control unit 26. The display control unit 26 superimposes the character pattern on the background video and displays it on the monitor 27.
[0020]
On the other hand, the CDV player 28 stores a large number of still images of original singers of karaoke songs. Each still image is identified by a singer code. During the screening of information such as new music information and best 20 information, the CPU 10 inputs character information such as a song name and operation instruction of the song to be introduced to the character display unit 25 and also gives the CDV player 28 the singer code of the original singer of the song. input. The character display unit 25 converts the music title and operation instructions into a character pattern and outputs the character pattern to the display control unit 26. Further, the CDV player 28 reads out a still image of the singer identified by the singer code and outputs it to the display control unit 26. The display control unit 26 combines the still image and the character pattern to form a screen as shown in FIG.
[0021]
FIG. 2A is a diagram showing a partial configuration of music data. The music data is composed of a header, a musical sound track, a character display track, an audio track, a DSP control track, a control information track, and an audio data section. The header is composed of various data relating to the music data (music number, music title, genre, release date, performance time, singer name, singer code, etc.).
[0022]
In addition, the musical sound track is implemented with data for generating musical sounds of karaoke performance, and is composed of a plurality of tracks in charge of a plurality of parts such as a piano, a stringed instrument, and a rhythm part. The musical sound track is composed of event data for instructing musical sound generation and muting and the like, and delta time data in which the read timing of the event data is represented by a time interval between the event data. The event data includes data for adjusting or changing the tone color (parameter change, program change, etc.), in addition to the data for instructing the tone generation and muting (note on data, note off data). In addition, initial parameters for resetting and initializing the sound source 19 and the like are collectively written as event data at the beginning of the musical sound track prior to the start of the karaoke performance. Sent to the sound source 19 and the like.
[0023]
The character display track is sequence data that implements the song title and lyrics of this karaoke song, and is composed of character display data (event data) and delta time data indicating the time interval of each event data. Note that this character display track data is not general-purpose MIDI data, but in order to unify the implementation and facilitate the work process, the audio track, DSP control track, etc. including this track are all in MIDI format. is described. The character display data is composed of character data of one line of lyrics, display coordinates of the lyrics, and wipe sequence data for controlling color change and erasure.
[0024]
The audio control track is a track for controlling the reproduction timing of a plurality of types of back chorus data stored in the audio data section, and includes audio designation data and delta time data that are event data. The voice designation data has contents for designating which voice data is to be pitch-shifted to which frequency and to be generated at which volume.
[0025]
The DSP control track is composed of event data and delta time data for controlling the functions of the DSPs 21a and 21b. The event data is data for instructing what kind of effect is to be given to the musical sound signal. Event data for resetting and initializing the DSP 21 and the like are collectively written in the head portion of the DSP control track in the same manner as the musical sound track.
[0026]
The control information track is a track storing information such as time data, beat (beat timing) mark, 1 chorus end mark, 2 chorus end mark, sub start mark, sub end mark of this song. The various mark data is event data for instructing each timing. Here, the chorus is the most exciting part of the karaoke song, and is usually the most well-known part of the karaoke song.
[0027]
When the karaoke performance is executed, the above-mentioned tone track, character display track, voice control track, DSP control track, and control information track are read synchronously based on the same clock signal. Output to the corresponding operation unit.
[0028]
FIG. 5B is a diagram showing the configuration of information data. The left side shows the best 20 information data, and the right side shows the new score information data. The best 20 information data records the song numbers of the top 20 requested songs and their rankings, and the new score information data records the song numbers of recently released songs and their release dates. is there. Since the information data is extracted from the music data, a lot of data for the screening is constructed in such a very simple manner.
[0029]
3 to 5 are flowcharts showing the information screening operation and the screening preparation operation of the karaoke apparatus. FIG. 6 is a diagram showing a display example of a monitor screen when the best 20 information is shown as an example of information. The information screening operation is registered in the HDD 14 (music data file 14a) of the karaoke device such as best information and new musical score information when there is no karaoke performance reservation and no karaoke performance is performed. This is an operation to introduce "recommended songs" among the karaoke songs being played. In addition, since the screening preparation operation continuously plays the chorus portion of multiple karaoke songs in the information screening operation, the music data is read and the sound source is set up in parallel with the information screening operation (behind the information screening operation). Is the action.
[0030]
The CPU 10 starts this operation when there is no request for a certain period of time without performing the karaoke performance. First, the information data is loaded from the information data file 14b of the HDD 14 to the information data reading area 12b of the RAM 12 (s1). It is assumed that which of the information data stored in the information data file 14b is to be loaded is determined in advance by a schedule. Further, as described above, since the information data has a small data amount, the loading is completed in a very short time. When the loading of the information data is completed, a screening preparation operation (FIG. 5) is started.
[0031]
Here, the screening preparation operation will be described with reference to FIG. In this operation, first, 0 system is designated as a system for preparing a screening (system for listening data read area 12c in RAM 12 and system for performance unit). That is, the system pointer k is set to 0 (s31). Then, it is determined whether or not the data prepared previously for this system has been finished (s32). When the process proceeds from s31 to s32, since the data has not been prepared before that, the determination of s32 is always positive and the process proceeds to s33. In s33, one tune number written in the loaded information data is read (s33). A plurality of music numbers are written in the information data, but s33 is read one by one in order from the top. That is, the operations from s32 to s41 are repeated for the number of songs written in the information data.
[0032]
The music data identified by the music number is searched from the music data file 14a (s34). When the corresponding music data is retrieved, the music title and singer code are read from the header (s35). Next, the data of each track is read in order from the beginning, and the performance data from the climax start mark to the climax end mark of the control information track is written into the audition data read area 12c of the system k. Even if the data is before the start mark, the parameter information for sequentially setting up the sound source 19 and the DSP 21 while the music is in progress is stored, and sent to the sound source 19 and the DSP 21 together so that the data after the start mark. It is assumed that the parameter setup of (2) is correct (s36). The operation of s36 takes several seconds. When the operation of s36 is completed, an instruction for completion of screening (trial listening) is given to the information screening operation (s37). This instruction is performed by an operation such as setting a sequential completion flag, for example.
[0033]
Next, it is determined whether the currently processed song is the first song among the songs having a plurality of song numbers written in the information data (s38). If it is not the top, a progress part for smoothly connecting the chorus of the immediately preceding song and the chorus of the current song is created (s39). Thereafter, it is determined whether or not there is a next song (s40). If there is a next song, the system to be prepared is reversed (s41), and the process returns to s32. If there is no next song (if it is the last song), the operation ends itself even if the front operation (information screening operation) has not ended.
[0034]
Returning to FIG. 3, after starting the screening preparation operation, the title of this information is displayed (s3: refer to FIG. 6A). As shown in FIG. 6A, in this screen display, whether this information is displayed together with the title in both the title display and the chorus performance (medley mode) or only in the title display (display mode) Is selected. The selection operation is performed by turning on the 0 key of the commander 3 (numeric keypad) when selecting the medley mode, and turning on the 1 key of the numeric keypad when selecting the display mode. In s4, the contents of this selection operation are determined, and if the medley mode is selected, the process proceeds to the operation of s5 or less, and if the display mode is selected, the process proceeds to the operation of s19 or less. If the numeric keypad (0/1) has not been operated for a certain period of time with the display shown in FIG. 6A, the operation automatically proceeds to the medley mode (s5 or less).
[0035]
In s5, the system i to be screened first is set to 0. In s6, it is determined whether or not the preparation of the system to be screened from now on, that is, whether the performance data is read and the sound source 19 and DSP 21 are set up. If the screening is not ready, it waits until preparation is completed in s6. When the preparation for the screening has been completed, the singer code is read out first, the singer code is sent to the CDV player 28, and the still image of the original singer is read out (s7). At the same time, the music name is transmitted to the character display unit 25, thereby converting the character information such as the music name into a character pattern. These are synthesized by the display control unit 26 and displayed on the monitor 27 (s8). An example of this display is shown in FIG. In parallel with this display operation, the performance data of the rust portion read out in the screening preparation operation is output to the sound source 19 and chorus processing unit 20 of the system i to start the performance (s9). When the user wants to sing the song while listening to the performance sound while viewing the display of FIG. 6B, the user operates the 0 key of the commander 3, and to view the next song, 1 of the commander 3. Turn on the key.
[0036]
If there is a key operation by the user, the process proceeds from s10 to s12, and if it is a performance reservation key (0 key), the screening of this information CM is finished as it is (s15), and the karaoke performance operation of the reserved music is started. On the other hand, if the next song key (1 key) is turned on, it is determined whether there is a next song in the song number list of the information data (s13). If there is a next song, the system is reversed. (S14), returning to s6. If there is no next song, the screening of this information CM ends. Even if the user does not perform any operation, when the performance of the chorus part is completed, or when the performance for a predetermined time (about 10 seconds or 20 seconds) is completed (s11). ), Automatically proceeds to s13 to introduce the next song.
[0037]
On the other hand, when the display mode is selected in s4 and the operation proceeds to s19, first, the system i to be screened is set to 0 (s19). In s20 and below, first, the singer code written in the trial data read area 12c of the system to be screened this time is read, the singer code is sent to the CDV player 28, the still image of the original singer is read (s20), and the song name is changed. By transmitting to the character display unit 25, character information such as a song name is converted into a character pattern. These are synthesized by the display control unit 26 and displayed on the monitor 27 (s21). An example of this display is shown in FIG. When the user wants to sing the song by looking at the display of FIG. 6C, the user operates the 0 key of the commander 3, and turns on the 1 key of the commander 3 to view the next song. If you want to audition the chorus part of the song, turn on Commander 3's 2 key.
[0038]
If there is a user key operation, the process proceeds from s22 to s24. When the audition key (2 key) is operated, preparation for audition is completed, that is, whether the performance data of the climax part is read out in the audition data reading area 12c, and the sound source 19, DSP 21, etc. are set up Is determined (s25). If it is not ready for trial listening, it waits until preparation is completed in s25. When preparation for audition is completed, the performance operation is started (s26). The user can operate the performance reservation key (0 key) or the next music key (1 key) again after operating the trial listening key (2 key).
[0039]
If the operated key is the performance reservation key (0 key), the screening of this information CM is finished as it is (s29), and the karaoke performance operation for the reserved music is started. If the next song key (1 key) is turned on, it is determined whether there is a next song in the song number list of the information data (s27). If there is a next song, the system is reversed. (S28), returning to s20. If there is no next song, the screening of this information CM ends. Even if the user does not perform any operation, when the chorus part finishes playing or when a certain time has passed (s23), the process automatically proceeds to s27 to introduce the next song.
[0040]
With the above operation, when information introducing the best 20 or new music is screened, it is possible to select whether to make a medley performance of the rust portion for all the songs or to audition the climax portion only for the selected song. In addition, when a selected song is reserved and selected, karaoke performance of the song can be automatically started.
[0041]
In the above embodiment, the display of a plurality of song names is sequentially performed by switching the screen, but this may be performed by scrolling. Moreover, although the original singer is displayed as a still image, it may be a moving image. Further, when there are two video processing units (such as the display control unit 26), the screen can be prepared in the back process.
[0042]
In the above embodiment, the singer code and the song name are read from the header of the song data. However, this may be written in the information data in advance.
[0043]
【The invention's effect】
As described above, according to the present invention, when a karaoke device stores, that is, when a song name of karaoke song data that can be played is displayed and introduced, a part of the song is automatically played. Can better introduce the song. Even if the user knows the song (melody) but does not know the song name, the song can be linked to the song name by this performance, and even such a song can be reserved for performance.
[0044]
In addition, since the partial performance of the karaoke song can be turned on / off, a user who wants to search for information can efficiently search.
[0045]
Furthermore, by displaying the song name and partial performance, and displaying the face of the singer (original singer) corresponding to the karaoke song, the song can be introduced in more detail.
