BACKGROUND OF THE INVENTION
The present invention provides karaoke equipment In place Related.
[0002]
[Prior art]
In online karaoke, etc., in order to meet the needs of users and acquire new users, the sound source version of the karaoke device is often upgraded and the music data version corresponding to this sound source version upgrade is performed. .
[0003]
Here, the version upgrade of the sound source is performed by installing a sound source program corresponding to the new version into the existing sound source or replacing the existing sound source with a new version of the sound source. Further, the sound source version may be upgraded in such a manner that an audio data decoder capable of generating a chorus sound or the like that is difficult to generate with a normal sound source is added. In this specification, the term “sound source” means not only a sound source that generates musical sounds (sound source in a narrow sense) but also a sound source in a broad sense that includes a device that generates a human voice such as an audio data decoder. Yes. The “sound source” referred to in the claims is also a sound source in this broad sense.
[0004]
On the other hand, version upgrade of music data is performed by a procedure in which a new version of music data is transferred from a host computer at the center to the karaoke device and replaced with existing music data on the karaoke device side. In the version upgrade of the music data, the tone color of a specific part among the parts constituting the music data may be changed. In some cases, the version of music data is upgraded in such a manner that a chorus part is added to music data that does not include chorus.
[0005]
[Problems to be solved by the invention]
By the way, the version method of the sound source and music data in the above-described conventional karaoke apparatus has the following problems.
[0006]
(1) Problems related to music data distribution accompanying version upgrade
As described above, when the music data is upgraded in the conventional communication karaoke or the like, since the entire new version of the music data is distributed from, for example, the host computer of the center to the karaoke device, traffic and distribution costs are increased. I was invited.
[0007]
(2) Problems related to version management of sound source and music data
For example, in the communication karaoke system, it is assumed that the music data distributed from the center to each karaoke device is upgraded in accordance with the new version of the sound source as the new version of the sound source becomes popular. In this case, there is no problem as long as the sound sources of all karaoke apparatuses receiving distribution of the new version of the music data are switched to the new version. However, it may happen that the sound source cannot be upgraded for some karaoke devices, and even if the sound source of all karaoke devices can be upgraded, the version of the sound source is upgraded. Is difficult to perform at the same time when the music data is upgraded. Therefore, depending on the karaoke apparatus, although the sound source is the old version, the distributed music data corresponds to the new version of the sound source.
[0008]
Here, depending on the music data, there may be included part data that uses a tone color that can be generated only by the new version of the sound source. In this case, the corresponding part cannot be played normally. In addition, the timbre corresponding to a specific part may have been changed due to version upgrade of the music data. In such a case, if the sound source is the old version, the timbre is different from the timbre that should be originally generated. The part is played.
[0009]
In order to avoid such discrepancies between the sound source and the music data version, each karaoke device side manages the version of the music data so as to store the music data corresponding to the version of the sound source, or distributes the music data On the center side, it is necessary to manage the version of the music data so that the music data matching the version of each sound source is distributed to each karaoke apparatus. However, when performing version management of such music data, a great burden is imposed on the administrator on the karaoke apparatus side or the administrator on the center side.
[0010]
The present invention has been made in view of the circumstances described above, and can reduce the traffic and communication cost due to the distribution of music data accompanying the upgrade of music data, and can perform troublesome version management as described above.

[0052]
Substitution information is referred to when selecting part data. The contents of this substitution information are as follows. First, for each part of “GUITER” and “STRINGS1” in the musical sound track, alternative part data was added in the first version upgrade (“PART17” and “PART18”), but the second version upgrade. However, the alternative part data is not added. Therefore, the substitute information corresponding to these parts is “1”. In addition, for each part of “STRINGS2” and “STRINGS3” in the musical sound track, alternative part data was added in the first version upgrade (“PART19” and “PART20”), and also in the second version upgrade. Alternative part data has been added (“PART21” and “PART22”). Therefore, the substitute information corresponding to these parts is “2”.
[0053]
Next, the CPU 1 corresponds to “control means” and “music data update means” in the claims, and is means for controlling the entire karaoke apparatus in accordance with the system program described above. The main functions of the CPU 1 are as follows.
[0054]
Among the main functions of the CPU 1, there are the following two as specific to the present embodiment.
a. Version upgrade of song data
When alternative part data is received from the center 300, music data is generated by merging the alternative part data and the music data. Details of this version upgrade operation will be described later.
[0055]
b. Karaoke performance control
When the substitute information is included in the music data to be played, the CPU 1 outputs the substitute information to the musical tone version control unit 20 (described later) in the musical instrument sound source 9. After outputting this alternative information, the CPU 1 reads event data from each track in parallel and supplies each event data to the corresponding units. More specifically, when the CPU 1 reads the performance event data of each part written on the musical tone track in the music data, the performance event data is sent to the musical instrument sound source 9 and the lyrics display event data in the lyrics track. Are read out to the display control unit 7 respectively. Further, when the CPU 1 reads the audio event data in the audio track, the CPU 1 reads out the audio data i (i = 1 to m) designated by the audio data number in the audio event data from the RAM 3, and the audio data Data related to the pitch and volume in the audio event data is added to i (i = 1 to m), and then output to an audio data decoder (not shown).
[0056]
Next, in accordance with the lyrics display event data in the lyrics track supplied from the CPU 1, the display control unit 7 generates a character string of lyrics corresponding to the music to be played, and supplies this from an LD playback device (not shown). The video signal (background video) to be synthesized is output to the display device 8. The display device 8 displays information supplied by the display control unit 7.
[0057]
The musical instrument sound source 9 generates and outputs musical sound signals such as musical instrument sounds according to the performance event data in the musical sound track supplied by the CPU 1. The detailed configuration and operation of the musical instrument sound source 9 will be described later. The microphone 10 converts a vocal sound emitted by the singer into an electric signal (hereinafter referred to as “vocal sound signal”) and outputs the electric signal to the mixer 11. The mixer 11 mixes and outputs the musical sound signal supplied from the musical instrument sound source 9, the vocal sound signal supplied from the microphone 10, and the audio signal supplied from an audio data decoder (not shown). The signal output from the mixer 11 is amplified by an amplifier (not shown) and output by a speaker (not shown).
[0058]
Next, the detailed configuration of the musical instrument sound source 9 will be described with reference to FIG. As shown in FIG. 7, the musical instrument sound source 9 includes a musical tone version control unit 20 and a musical tone signal generation unit 21.
[0059]
The musical tone version control unit 20 selects information suitable for the version of the musical tone signal generation unit 21 from the performance event data supplied from the CPU 1, and supplies the information to the musical tone signal generation unit 21. Details of the operation of the musical tone version control unit 20 will be described later.
[0060]
The musical tone signal generation unit 21 generates a musical tone signal such as an accompaniment sound according to the information supplied by the musical tone version control unit 20, and outputs the musical tone signal to the mixer 11. The musical tone signal generator 21 stores information indicating the version of the sound source (hereinafter referred to as “sound source version information”) in an internal storage device (not shown). That is, every time the musical sound signal generation unit 21 is upgraded, the sound source version information is updated by a predetermined operation such as a staff member or by the control of the CPU 1. This sound source version information does not exist for sound sources that have not been upgraded. This sound source version information is supplied to the musical tone version control unit 20 at the start of karaoke performance. The sound source version information may be written in the hard disk device 6 or the like. The above is the detailed configuration of the musical instrument sound source 9 in the karaoke apparatus according to the present embodiment.
[0061]
A-2: Operation of the first embodiment
A-2-1: Upgrade music data version
Hereafter, the operation | movement at the time of version upgrade of the music data in the karaoke apparatus which is this embodiment is demonstrated.
[0062]
For example, when a new version of a sound source or music generation software is provided to the market, the center 300, which is the music data distribution source, can newly generate such a version-up sound source. Create alternative part data and alternative information for performing with a tone. On the other hand, when a predetermined operation is performed by a staff member, a store clerk, a user, or the like who manages the karaoke device and the communication control unit 5 of the karaoke device is instructed to acquire the substitute part data and the substitute information, the instruction is given. The received communication control unit 5 transmits the above-described substitute part data and substitute information distribution request to the center 300. The center 300 that has received the distribution request distributes the alternative part data and the alternative information to the karaoke apparatus 100 that has transmitted the distribution request. At this time, the music part number of the music data to which the alternative part data and the alternative information are to be added is added to the distributed information.
[0063]
When the communication control unit 5 in the karaoke apparatus 100 receives these pieces of information, it stores them in the hard disk device 6. Next, the CPU 1 reads the song data corresponding to the song number added to the information, the received substitute part data, and the substitute information. These pieces of information are merged, and the merged music data is stored in the hard disk device 6 again.
[0064]
More specifically, the above merging process is performed as follows. First, the CPU 1 adds the received substitute part data after existing tail part data or substitute part data. If the replacement information is not added to the existing part data, that is, if the music data has never been upgraded, the received replacement information is added after the last part of the replacement part data. That is, when the musical tone track in the music data shown in FIG. 2 is upgraded, alternative information is newly added at the end of each part data of the musical tone track in the musical piece data, and the musical tone shown in FIG. It is upgraded to a track. On the other hand, if the replacement information is added to the existing part data, that is, if the music data has been upgraded before, the received replacement part data is added and then added. Is replaced with the received substitute information (see FIG. 6). The above is the operation when the music data is upgraded in the karaoke apparatus according to the present embodiment.
[0065]
A-2-2: Operation during karaoke performance
When the user inputs a music number by operating the operation unit 4 or a remote controller (not shown), the CPU 1 reads music data corresponding to the input music number from the hard disk device 6 and writes it in a predetermined storage area of the RAM 3.
[0066]
Next, the CPU 1 reads out the user bank data included in the header of the music data stored in the RAM 3 and sets it in the musical instrument sound source 9. When the music data includes alternative information, the alternative information is supplied to the musical tone version control unit 20 of the musical instrument sound source 9. Then, the CPU 1 reads the tracks constituting the music data in the RAM 3 in parallel, and supplies the event data in the track to each unit. Among these event data, performance event data read from the musical tone track is supplied to the musical instrument sound source 9.
[0067]
Here, the musical tone version control unit 20 in the musical instrument sound source 9 outputs the performance event data supplied by the CPU 1 to the musical tone signal generation unit 21 as it is when the alternative information is not supplied from the CPU 1.
[0068]
On the other hand, the operation of the musical tone version control unit 20 when the substitute information is supplied from the CPU 1 at the start of karaoke performance is as follows. In the following description, as shown in FIGS. 6A and 6B, the replacement part data of “GUITER” and “STRINGS1” in the musical sound track is once replaced with “STRINGS2” and “STRINGS3”. A case where part data is added twice will be described as an example. Further, in the following description, the case where sound source version information does not exist (when the sound source is not upgraded), the case of “1”, and the case of “2” or more will be described separately.
[0069]
a. When no sound source version information exists
In this case, although the substitute part data is added to the musical sound track, the sound source has not been upgraded, so that a new tone corresponding to the substitute part data cannot be generated. Therefore, the musical tone version control unit 20 supplies the musical event signal generation unit 21 with the performance event data in the common part data and the first edition part data among the performance event data supplied by the CPU 1, as shown in FIG.
[0070]
b. When the sound source version information is “1”
In this case, the tone signal generator 21 can generate the timbres indicated by “PIANO (PART1)” to “STRINGS3 (PART20)”, but the “STRINGS2 (PART21)” and “STRINGS3 (PART22)” parts. A musical tone signal corresponding to a new timbre indicated by data cannot be generated. Accordingly, as shown in FIG. 9, the musical tone version control unit 20 supplies the musical tone signal generation unit 21 with the common part data and “GUITER (PART 17)” to “STRINGS 3 (PART 20) among the alternative part data. Event data in the part data.
[0071]
c. When the sound source version information is “2” or higher
In this case, the tone signal generator 21 can generate all the timbres indicated by the performance event data supplied by the CPU 1. Therefore, the musical tone version control unit 20 supplies the musical tone signal generation unit 21 with the common part data and “GUITER (PART 17)” and “STRINGS 1 (PART 18) among the alternative part data as shown in FIG. "," STRINGS2 (PART21) "and" STRINGS3 (PART22) "in the performance event data.
[0072]
As shown in the above a to c, performance event data instructing generation of the latest musical tone signal among musical tone signals that can be generated by the musical tone signal generating unit 21 is sent from the musical tone version control unit 20 to the musical tone signal generating unit. 21 is supplied. The musical tone signal generator 21 supplied with the performance event data in this way generates a musical tone signal such as an accompaniment sound according to the performance event data and outputs it to the mixer 11.
[0073]
As described above, according to the present embodiment, even if the music data is upgraded, it is not necessary to distribute all the new version of the music data from the center to the karaoke apparatus. Traffic and distribution costs can be reduced. In addition, since it is not necessary to manage the version difference between the music data and the sound source, the burden on the management of the karaoke apparatus can be reduced.
[0074]
