[0034]
The age specification means 31 announces the music of the music ID provided as attribute
information of the music DB 51 of FIG. 2A when the music to be played by karaoke is read from
the music DB 51 based on the music ID. It is a program that reads out and specifies the age.
[0035]
The processing setting unit 32 includes an equalizing setting unit 32A, a panpot setting unit 32B,
a simulated noise addition setting unit 32C, a simulated echo setting unit 32D, and a setting table
32E, and the age setting for the musical performance of the karaoke performance. It is a program
set to the reproduction feature according to the announcement age specified by the specifying
means 31.
The reproduction feature according to the presentation age refers to the characteristics of
frequency characteristics, the localization of left and right channels, noise, echo, etc. in the
predetermined reproduction means (for example, vacuum tube radio, jukebox, etc.) at the time of
presentation. The setting is performed by the equalizing setting unit 32A, the panpot setting unit
32B, the simulated noise addition setting unit 32C, and the simulated echo setting unit 32D. Note
that the setting of the reproduction feature may be all or any of the above.
[0036]
That is, the equalizing setting unit 32A processes the frequency characteristic that is the
reproduction feature according to the announcement age of the performance signal, and the
panpot setting unit 32B locates the reproduction feature according to the announcement age of
the performance signal (span feeling of sound image) The simulated noise addition setting unit
32C simulates and adds noise noise of an analog record board, which is a reproduction feature
according to the announcement age, to the performance signal, and the simulated echo addition
setting unit 32D has characteristics according to the announcement age Echo effects are added
to the audio signal only. Each of these will be specifically described below.
[0037]
Specifically, as shown in Fig. 2 (C), the reproduction characteristics of the music listening
07-05-2019
11
environment of the frequency characteristics according to the announcement age are warm tones
of monaural vacuum tube radios and jukeboxes in the 1960s. Yes, it is a reproduction feature of
the echo effect of early tape-type echo machines, where the noise of the analog record is audible
and wow and flutter are noticeable.
[0038]
Also, in the 1970's, it is a reproduction feature of the sound of a large stereo device that has
spread to general households during high growth period, and the frequency characteristics and
localization feeling (lateral spread) are improved compared to the 1960's. .
In the 1980's, it is a reproduction feature of CD sound source and mini component sound (socalled "don's char").
[0039]
Based on these, in the setting of the reproduction feature of the music listening environment in
equalization, in the 1960s, the pass frequency of the equalizer is set to 40 Hz to 15 kHz, and the
low band of 100 Hz or lower and the high band of 10 kHz or more slightly lower , Reproduce the
frequency characteristics of vacuum tube radio and jukebox at the time. In the 1970's, the high
frequency is reproduced as flat by setting the pass frequency of the equalizer to 20 Hz or more
and 20 kHz or less. In the 1980's, the low pass and high pass are emphasized by setting the pass
frequency of the equalizer to 10 Hz or more and 40 kHz or less. After the 1990's, the pass
frequency of the equalizer is 10 Hz or more and 80 kHz or less, and the entire reproduction is
flat. The setting values by the equalizing setting unit 32A are reflected on the setting table 32E,
and are set in the mixing amplifier 14.
[0040]
Specifically, as shown in FIG. 2 (C), the setting of reproduction characteristics of the music
listening environment in the localization of the left and right channels according to the
announcement age is, for the 1960s, the performance signals of the left and right channels of
karaoke performance. It is close to monaural playback with no sense of stereo broadening by
setting the localization nearly at the center, and it is about halfway between monaural and stereo
07-05-2019
12
in the 1970s, perfect stereo in the 1980s, and after 1990s. It becomes a reproduction feature
with a full stereo surround. These setting values by the pan pot setting unit 32B are reflected on
the setting table 32E, and are set to the mixing amplifier 14. A technique well-known in the field
of sound can be used for surround addition, and in this embodiment, it can be realized by a DSP
provided in the mixing amplifier 14 which is a digital mixer.
[0041]
Specifically, as shown in FIG. 2 (C), the setting of the reproduction feature of the music listening
environment in the noise according to the announcement age is a music that simulates the sound
simulated by the "shattering" noise (so-called LP noise) of the analog record Apply at a
predetermined volume level throughout. The predetermined volume level may be, for example, a
level at which noise is noticeable in a quiet part before the start of the karaoke performance or in
the music, and is not so noticeable in a part where the volume of the karaoke performance is
large. In the 1960s, the level is increased, in the 1970s, the level is decreased, and after the
1980s and 1990s, so-called LP noise does not exist due to the appearance of CD. The setting
values by the simulated noise setting unit 32C are reflected on the setting table 32E, and an
instruction is given to the simulated noise adding unit 33 described later.
[0042]
Specifically, as shown in FIG. 2 (C), the setting of the reproduction feature of the music listening
environment in the echo effect according to the announcement age is accompanied by a wow and
flutter unique to the initial echo machine using free running of the tape. The echo is simulated
and added to the voice signal of singing. In the 1960s, the tape type echo effect is set to flutter,
in the 1970s, it is reduced, and in the 1980s and 1990s, there is no flutter. The setting values by
the simulated echo setting unit 32D are reflected on the setting table 32E, and are set to the
mixing amplifier 14.
[0043]
The simulation noise addition unit 33 reads the simulation noise data 55 stored in the storage
unit 30 according to the instruction of the simulation noise addition setting unit 32C of the
processing setting unit 32, performs loop reproduction, and outputs it to the mixing amplifier 14
. When the tone generator 26 is provided with a timbre such as LP noise and the simulated noise
07-05-2019
13
data 55 is MIDI data, the simulated noise addition setting unit 32C reads the MIDI data of the LP
noise and the music performance control unit It becomes processing to output to 25.
[0044]
The setting of addition of the reproduction feature in the processing setting means 32 may be
performed not only on the performance signal but also on the voice signal of singing matched to
the karaoke performance and mixed with the processed karaoke performance signal. In this case,
the target of the echo effect of the characteristic according to the announcement age by the
simulated echo addition setting unit 32D is to be added only to the audio signal.
[0045]
The background image display processing means 34 is an image of a corresponding age from the
age-specific video DB 54 of the storage unit 30 based on the age specified by the age specifying
means 31 at the time of karaoke performance , Etc. as a whole of the background image, and
reproduced by the image display control means 24.
The same applies to the case where the age-based video is file data in which the video (video at
that time) taken as it was taken for each age is the entire background video.
[0046]
By the way, as described above, when the video according to the age is a part of the file data of
the background video, the background video display processing means 34 outputs the normal
background video according to the musical composition to the video DB 52 of the storage unit
30. While reading out the image, the image of the corresponding age is read out from the agespecific image DB 54, a part of the age-specific image is inserted into an ordinary background
image, and output to the image display control means 24 for display. The background image
display processing means 34 may process the normal background image read from the image DB
52 of the storage unit 30 according to the age (for example, monochrome display or sepia
display).

Therefore, FIG. 3 shows an explanatory view of retro reproduction setting selection of karaoke
performance according to the announcement age by the remote input / output device of FIG. 1,
and FIG. 4 shows an explanatory view of each specific processing of retro reproduction. Here, the
karaoke performance according to the announcement age is called retro reproduction. First,
when the user selects a music selection in the remote input / output device 17, the music
selection music registration means 17A is executed, and the same music selection screen as
before is displayed as shown in FIG. The screen which made the candidate of the music of is
displayed on remote control display part 17C.
[0048]
When selecting the music, there is a selection display 17D for retro reproduction, and if retro
reproduction is desired according to the user's preference, retro reproduction is retro
reproduction setting means by touching the display position. The retro play flag is attached to
the music ID of the selected music by being touched by the operation button 17 E of
“transfer”, which is set by 17 B, and transmitted to the karaoke body 12. In the karaoke body
12, as shown in FIG. 3 (B), the music piece ID with the retro reproduction flag attached thereto is
reserved and registered in the reservation queue 41 of the RAM 23.
[0049]
The performances are started in the order of reservation registration in the reservation queue 41
shown in FIG. 3 (B), and when the performance of the music B whose retro reproduction flag is
“ON” shown in FIG. When read out from the music DB 51 based on the music ID, the age
specifying means 31 reads out and specifies the announcement age of the music of the music ID
from the attribute information shown in FIG. 2A of the music DB 51. Here, as shown in FIG. 4A, it
is specified as a music of the 1960s.
[0050]
The equalizing setting unit 32A refers to the setting table 32E shown in FIG. 4 (A) in the
processing setting means 32 based on the announcement date "1960's" of the music specified by
the age specifying means 31. 4 ”to the mixing amplifier 14, the panpot setting unit 32B sets the
setting value“ PA-4 ”to the mixing amplifier 14, and the simulated echo setting unit 32D mixes
the setting value“ EC-4 ”. While setting for the amplifier 14, the simulation noise addition
setting unit 32C instructs the simulation noise addition unit 33 to perform simulation noise

[0051]
On the other hand, in the background video display processing means 34, as shown in FIG. 4B,
the video of the age-specific video ID corresponding to the 1960's is read out from the agespecific video DB 54 of the storage unit 30, By transmitting, retro reproduction of the audio
signal of singing along with the karaoke performance and the karaoke performance is performed
together with the background image.
[0052]
In this manner, a performance signal corresponding to the release date of the music is emitted
and a background image is displayed, and the reproduction characteristic of the performance
signal of the music is determined according to the release age as the music listening environment
for the background image. It is possible to match reproduction features.
Further, by performing retro-reproduction not only on karaoke performance but also on the
voice signal of singing, reproduction characteristics of the music listening environment of the
presentation age can be matched more.
Furthermore, the music listening environment can be formed according to the user's preference
by setting the processing setting to be valid or invalid for each of the music pieces when
selecting music pieces for karaoke performance and making a reservation registration in the
reservation queue 41. It is possible.
[0053]
