[0002]
[Prior art]
2. Description of the Related Art Conventionally, a karaoke apparatus that displays a background image of a song along with the performance of karaoke is known. In this type of karaoke device, the amount of background video data is enormous, so instead of holding background video data corresponding to each song, it holds several types of background video data. In addition, it is common to select and display a background video that matches the genre of the song (attributes such as the music genre and season of the song). For example, in a sound source type karaoke apparatus, genre information is included in the header portion of karaoke song data (MIDI data, etc.), and this is used as a search key to transmit video data suitable for the song to an LD (laser disc) or CD- A background image matching the music is displayed by searching from the ROM or the like and reproducing it.
[0003]
[Problems to be solved by the invention]
By the way, the background video displayed with the performance of karaoke is various, such as place, atmosphere, characters and objects, and the scene changes one after another in the video data corresponding to one song as the song progresses. However, in the conventional karaoke apparatus, as described above, the background video unique to the karaoke song is not reproduced in synchronization with the performance, but the background video suitable for the genre of the song is simply selected and simultaneously selected. Even if the sound effect is given along the progress of the song only by playing, the sound effect is not given according to the scene of the background image. For this reason, the background image has only an effect as a BGV (background video) and has a poor sense of reality.
[0004]
The present invention has been made under such a background, and an object of the present invention is to provide a karaoke apparatus capable of enjoying a karaoke full of a sense of reality by providing an acoustic effect suitable for a background image.

[0011]
A hard disk 24 stores music data distributed from the host computer 1. That is, in each karaoke terminal, the music data supplied from the host computer 1 is temporarily stored in the hard disk 24 and is read and used.
[0012]
Reference numeral 25 denotes a communication I / F (interface), which receives music data transmitted from the host computer 1 and transfers it to the hard disk 24 by DMA (direct memory access).
[0013]
Further, reference numeral 26 denotes a panel I / F, which is a key input operation (for example, input of a song number, instruction to start or stop performance, setting of volume, tempo, etc.) on an operation panel of a karaoke apparatus body or a remote control terminal (not shown). And the detection result is supplied to the CPU 21 as input data.
[0014]
Next, reference numeral 27 denotes a sound source, which synthesizes a tone signal corresponding to the tone control data (included in the music data) supplied by the CPU 21 and outputs the synthesized tone signal to the mixer 28. An audio decoder 29 generates an audio signal corresponding to ADPCM data (audio data such as back chorus included in music data, or sound effect data referred to from video data described later) supplied by the CPU 21. This is output to the mixer 28. The mixer 28 mixes and outputs the musical sound signal supplied from the sound source 27, the back chorus or sound effect audio signal supplied from the audio decoder 29, and the singer's audio signal input from the microphone M.
[0015]
Reference numeral 30 denotes an effector, which gives various effects such as echo, reverb, delay, etc. to the output of the mixer 28 based on the effect imparting control data supplied by the CPU 21 (included in music data or video data). Further, 31 is a sound system, which removes noise components from the output of the effector 31 and then emits sound from a speaker (not shown).
[0016]
Next, reference numeral 32 denotes a background video reproduction device, which reproduces video data (details will be described later) for displaying a karaoke background video stored in a video storage medium such as a moving image CD. A video mixer 33 superimposes the font data of the lyrics read from the ROM 22 on the background video, and outputs this composite image. Reference numeral 34 denotes a display which displays a composite image of background and lyrics corresponding to the output of the video mixer 33.
[0017]
(3) Details of Music Data Next, details of music data will be described. As shown in FIG. 3, the music data for one music consists of a header, a musical sound track, a display track, an audio track, an effect control track, and an audio data area. The header is a portion in which various data relating to the song is written, and describes data such as a song number, a song name, a genre, and a performance time of the song.
[0018]
The musical tone track describes sequence data for controlling musical tone synthesis by the sound source 27, and is composed of event data for controlling sound generation, muting, etc., and duration data for controlling timing. In the display track, code information corresponding to the lyrics of karaoke to be displayed on the display 34 in synchronization with the progress of the song is described. In the audio track, address information and the like for reading out ADPCM data of sound effects such as back chorus from the audio data area in synchronization with the progress of the music are described. Further, the effect control track describes control data for controlling the effect to be given to the musical sound such as echo and reverb.
[0019]
(4) Details of Video Data Next, details of the video data will be described. As shown in FIG. 4, the video data for one song is composed of a header including genre information followed by video data in a predetermined time unit (hereinafter referred to as scene data) constituting a background video. Before each scene data, data for designating a sound effect to be generated in the scene (hereinafter referred to as a sound effect address) and data for controlling a sound field (hereinafter referred to as a sound field control parameter) are added.
[0020]
Here, as shown in FIG. 5, the sound data for generating the sound effects are various sound effects referred to by the sound effect address designated from the video data (whisper sound, seagull sound, walking sound, etc.). Are stored as data files of the ADPCM data. Note that this data file is distributed from the host computer 1 of the center station to each karaoke terminal 2 via the communication line N, similarly to the music data.
[0021]
The sound field control parameter is a parameter for controlling the delay time of the reflected sound by the effector 30 and the like. For example, if a place where the surroundings are open is displayed as a background image, such as a port or a coast, a sound field control parameter that increases the delay time (for example, infinite) is set accordingly. The In this case, a sound field is formed so that the sound can travel far away. Conversely, if a narrow place such as a room is displayed as a background image, a sound field control parameter for reducing the delay time is set correspondingly. In this case, a sound field in which the sound is confined in a narrow place is formed.
[0022]
B: Operation of Embodiment Next, the operation of the karaoke apparatus having the above configuration will be described. First, when the user inputs a karaoke song number from the remote control terminal, the song number is taken into the CPU 21 via the panel I / F 26. Thus, the CPU 21 searches the hard disk 24 for music data corresponding to the music number.
[0023]
When music data is searched, the genre information is read with reference to the header. Then, the address of the video data is obtained from the read genre information via a predetermined conversion table, and this is designated to the background video reproduction device 32. As a result, the background video playback device 32 searches the video storage medium for video data corresponding to the genre of the designated music and plays it.
[0024]
Thus, when music data and video data are searched, both data are reproduced in parallel. First, for music data, a musical sound track, a display track, an audio track, and an effect control track are synchronously reproduced by time division. As a result, the tone control data read from the tone track is supplied to the sound source 27, and the font data corresponding to the lyrics code read from the display track is supplied from the ROM 22 to the video mixer 23, from the audio data area specified by the audio track. The read ADPCM data is supplied to the audio decoder 29, and the control data read from the effect control track is supplied to the effector 30.
[0025]
On the other hand, for the video data, in parallel with the reproduction of the music data, the sound effect address and the sound field control parameter are read and the scene data is reproduced. Thereby, the ADPCM data of the sound effect designated by the sound effect address is transferred from the hard disk 24 to the sound decoder 29, the sound field control parameter is supplied to the effector 30, and the video signal obtained by the reproduction of the scene data is converted to the video mixer. 23. The generation timing of each sound effect is determined by a generation command (not shown) included in the video data.
[0026]
Thus, the sound source 27 synthesizes the karaoke musical sound corresponding to the musical sound control data, and the audio decoder 29 restores the sound such as the back chorus and the sound effect corresponding to the background video. Furthermore, after these musical sounds are mixed with the singing voice inputted from the microphone M in the mixer 28, effects such as echo and reverb are given by the effector 30, and the sound field control corresponding to the background video is performed. Sound is emitted from the speaker through the sound system 31. On the other hand, in parallel with the karaoke performance, the video mixer 23 superimposes the font image of the lyrics on the background video, and the composite image is displayed on the display 34.
[0027]
As described above, according to the present embodiment, sound effects corresponding to the background image displayed together with the performance of the karaoke can be added to the musical sound of the karaoke, and a sound field corresponding to the background image can be formed. As a result, for example, when a background image of a port is displayed, it is possible to add sound effects such as whistle sounds and seagulls to create a sound field that eliminates the sound. You can enjoy overflowing karaoke.
[0028]
C: Modification (1) In the above embodiment, after mixing all the karaoke musical sounds, sound effects corresponding to the background image, singing sound, etc. by the mixer 23, the effector 30 performs the sound field control corresponding to the background image. I applied. In this way, sound field control may be performed on some sound effects and singing voices instead of performing sound field control on all sounds. For example, when it is desired to control the sound field only for the sound effect corresponding to the background video, as shown in FIG. 6, the output of the audio decoder 29 is converted into the sound V1 of the back chorus and the sound effect V2 corresponding to the background video. In other words, an effector 30 ′ for performing sound field control on only the sound effect V 2 may be provided in the front stage of the mixer 28 so that only the effect specified by the music data is applied to the effector 30.
[0029]
(2) In the above-described embodiment, both the application of the sound effect corresponding to the background image and the sound field control are performed. However, the present invention is not limited to such a configuration, and only one of them is performed. However, it is possible to enjoy a sense of reality corresponding to the background image. In this case, the amount of data can be reduced as compared with the embodiment, and the advantage that the configuration is simplified can be obtained.
[0030]
(3) Further, the parameter for controlling the sound field is not limited to the delay time of the reflected sound, and the intensity and direction of arrival may be controlled.
[0031]
(4) Further, the video data and sound effect data files are not limited to the data format of the above embodiment, and other data formats may be adopted as long as the function according to the present invention can be realized.
[0032]
(5) Furthermore, in the above embodiment, the present invention is applied to online karaoke. However, the present invention is not limited to this, and can be applied to other karaoke apparatuses as long as the background video is displayed in parallel with the performance of karaoke. It is.
[0033]
【The invention's effect】
As described above, according to the present invention, since a sound effect and a sound field suitable for a background image can be formed, a user can enjoy karaoke full of realism.
