Operation unit switching device, operation unit switching method, and operation unit switching
program
[0001]
The present invention relates to, for example, an operation unit switching device, an operation
unit switching method, and an operation unit switching device for appropriately switching the
function of the operation unit operated when adjusting the level and the timbre of the audio
signal input to the audio adjustment device. About the program.

1
When producing a program for broadcasting, generally, an audio control console (device) called a
mixer (mixing console) is used.
This mixer is connected to a number of audio input / output devices such as speakers and
microphones, and each input device can be operated by operating an operation unit provided
with an encoder such as a slide or rotary volume, various switches, etc. For the corresponding
input channel, setting operation of adjustment parameters corresponding to dozens of
adjustment functions such as selection of input line, input level setting and correction,
adjustment of timbre, selection and adjustment of final output destination can be performed.
[0003]
By the way, the production stages of broadcast programs etc. can be roughly divided into three
stages of preparation stage before rehearsal, rehearsal stage and broadcast (on air) stage, and
parameters to be mainly adjusted are often different in each stage. For example, in the
preparation stage before rehearsal, confirmation and level adjustment regarding input and
output, in the rehearsal stage, adjustment regarding timbre such as applying reverb echo
according to the difference of performers such as gender and age, input and finality in
broadcasting stage It becomes a pattern such as output adjustment. For this reason, it is
necessary for the operator who performs the operation to select and operate a necessary
operation unit appropriately from a huge number of operation units according to each stage. In
particular, in the case of a large program or the like, several tens of input / output channels are
required, so that the operation burden on the operator is enormous.
[0004]
In order to cope with this, in the conventional mixer, encoders and switches physically installed
in the operation unit are set so as to be able to switch and play the role of operating these dozens
of adjustment functions. That is, the functions to be provided to the encoder and the switch are
grouped into function groups of the same type of function, and a plurality of function groups are
preset (preset). Then, by selecting any one of the preset function groups using a selection switch
or the like, it is possible to perform all parameter adjustment while switching the role given to
the encoder and switch of each channel.

[0005]
For example, as shown in FIG. 9, an operation unit M having an encoder EN, a switch SW, and an
application indicator UD is provided for each of the channels (CH1 to 8), and is disposed
corresponding to each of the channels. When one of the switch buttons (A to D) of a plurality of
function groups is selected, the encoder EN and the switch SW of that channel are all switched to
that function. More specifically, when the level adjustment function is A, if the A button is
selected, the functions of the encoder EN and the switch SW are switched to the level adjustment
function, and the function name is displayed on the application display UD. Then, when the
encoder EN and the switch SW are operated, the level adjustment of the channel can be
performed. JP-A-8-316752 JP-A-2003-101442
[0006]
However, in the prior art as described above, although all parameter manipulation can be
performed by a limited encoder and switch etc., when a certain function is given to the encoder
and switch, another function If you want to adjust the, you need to operate the switch button etc
again. The functions to be adjusted at each production stage are not only the main functions
exemplified above, but various adjustments need to be made frequently, which are different at
each production stage.
[0007]
Assuming such a situation, in the method of selecting and switching the button preset for each
function group, the operator must frequently select the button and perform switching each time
the adjustment operation is performed. It becomes excessive. In addition, entry of a function
switching operation between adjustment operations affects the operation response. For example,
in an imminent production stage such as during broadcasting, if the adjustment operation is
delayed with respect to the sudden change in voice of the performer, it is considered that the
sound itself to be broadcasted is affected and the program quality is lost. Be
[0008]
The present invention has been proposed to solve the problems of the prior art as described
above, and assigns to each operation unit a desired function according to a scene that requires
adjustment, and switches for each scene. Accordingly, it is an object of the present invention to

That is, in the present embodiment, based on the control signals from the control unit 20 and the
touch panel (display) 30 and the control unit 20 that constitute the switching device of the
plurality of operation units 10 and the functions assigned to these operation units 10. An audio
processing unit 40 is provided which processes and outputs an audio signal.
[0016]
As shown in FIGS. 3 to 5, a plurality of operation units 10 are provided for each of the channels
CH1 to CH8, and provided with rotary volumes operated by the push button type switch 11 and
the cylindrical knob, respectively. An encoder 12 is provided with an application indicator 13 for
displaying the assigned application.
Although the number of operation units 10 is two for each channel in FIGS. 3 to 5, the number is
not limited to this number.
In particular, in a general mixer, a larger number of operating units 10 are required.
[0017]
The control unit 20 includes a control unit 21, a memory 22, and input / output interfaces (I / F)
23 and 24. For example, as shown in FIG. 2, when the CPU operates according to a
predetermined program, the control unit 21 operates the input signal processing unit 21a, the
setting registration unit 21b, the switching control unit 21c, the setting extraction unit 21d, and
the control signal output unit It functions as 21e. The input signal processing unit 21 a is a unit
that processes input signals from the operation unit 10 and the touch panel 30. The setting
registration unit 21 b is a unit that performs registration in the memory 22 according to input
signals from the switch 11 and the touch panel 30. Therefore, the switch 11 and the touch panel
30 function as a setting input unit described in the claims.
[0018]
10-04-2019
6
The switching control unit 21 c is a unit that controls switching of the function assigned to the
operation unit 10 in accordance with the selection input from the touch panel 30. Therefore, the
touch panel 30 functions as a selection unit described in the claims. The setting extraction unit
21 d is a unit that extracts the setting of the memory 22 when performing the function
switching. The control signal output unit 21 e is a unit that outputs an input signal and a control
signal corresponding to the extracted setting to the sound processing unit 40, the touch panel
30, and the application display 13.
[0019]
The memory 22 is means for storing various settings, and in the present embodiment, in
particular, stores function assignment settings (hereinafter referred to as function-specific
settings) to the operation unit 10 grouped by function. The function-by-function setting storage
unit 22a and the scene-by-scene setting storage unit 22b that stores function assignment settings
(hereinafter referred to as scene-by-scene settings) to the operation unit 10 according to various
scenes such as program production doing. Here, the function-based settings are set in advance by
default, for example, and are displayed on the touch panel 30 with the buttons A to D for each
same type of function group. The scene-specific setting can be registered by the user, for
example, in the procedure described later, and is displayed on the touch panel 30 with the
buttons Macro1 and Macro2 for each registered group. Further, the name of the function
assigned to each operation unit 10 is displayed on the application display 13.
[0020]
Display data to be displayed on the touch panel 30 and the application indicator 13 is also stored
in the memory 22 and is set so that the above display can be performed by being appropriately
selected and output by the control unit 21. . Furthermore, the I / Fs 23 and 24 are interfaces that
mediate input and output of control signals between the control unit 20, the operation unit 10,
the touch panel 30, and the audio processing unit 40.
[0021]
Such a control unit 20 is typically realized by controlling the computer hardware
programmatically. The hardware configuration can be variously considered, for example, by a socalled chip that realizes each function and a peripheral circuit thereof, or by a system LSI that
10-04-2019

integrates a plurality of functions, and is not limited to a specific circuit. In addition, the hard
disk, the CD-ROM, the DVD-ROM, and other various recording media in which the program and
the program are recorded are an aspect of the present invention even if they are independent.
Therefore, for example, the control unit 20 can be realized by installing an application program
in a personal computer.
[0022]
The audio processing unit 40 adjusts an audio signal from an input device such as a microphone
for each channel based on a control signal output from the control unit 20 according to an
adjustment parameter input from the operation unit 10, and a speaker , Etc. are output to an
output device such as The speech processing unit 40 is basically the same as the well-known
technology, so the details thereof will be omitted.
[0023]
[Operation of Embodiment] The processing procedure according to the present embodiment as
described above will be described with reference to the external view of the operation panel in
Figs. 3 to 5 and the flowcharts in Figs. 7 and 8. [Registration Process] First, the flow of the
registration process will be described according to FIG. That is, in a state where the buttons A to
D are displayed on the touch panel 30 (step 701), when the user selects a button corresponding
to a desired function by pressing or touching the button, the selected function is selected. An
input signal shown is input to the control unit 21 (step 702). When the user presses the switch
11 of the operation unit 10 to which the function is to be assigned, an input signal indicating the
pressed switch 11 is input to the control unit 21 (step 703).
[0024]
In the control unit 21, the input signal processing unit 21 a identifies an input signal, and the
setting registration unit 21 b associates the selected function with the operation unit 10
corresponding to the pressed switch 11, for each scene of the memory 22. By storing in the
setting storage unit 22b, registration processing of setting for each scene is performed (step
704). For example, when the button C is selected and the switch 11 of the operation unit 10 of
the first stage in the channel CH1 is pressed, information identifying the operation unit 10 and
information identifying the function of C are associated and stored. After the above processing is
10-04-2019
8
performed on all the operation units 10 so as to correspond to the specific scene, the registration
is ended (step 705). The functions registered for each scene in this manner are button-displayed
(Macro 1 and Macro 2) on the touch panel 30 for each scene, as shown in FIGS. Note that
although Macro 1 and Macro 2 are displayed in FIGS. 3 to 5, the display contents may be freely
selected, and may be desired characters, figures, icons, etc. input by the user.
[0025]
[Switching Process] Next, a process of switching the function assigned to each operation unit 10
by selecting from among the buttons A to D and Macros 1 and 2 displayed on the touch panel 30
will be described according to FIG. That is, for example, when the user selects the button A
displayed on the touch panel 30 (step 801), the input signal processing unit 21a in the control
unit 21 identifies that the button A is selected, and the switching control unit 21c performs the
button It is determined that there has been a request to switch to the function corresponding to
A (step 802). Then, the setting extraction unit 21 d extracts the function-specific setting
corresponding to the button A from the function-specific setting storage unit 22 a in the memory
22 (step 803). Then, when the control signal output unit 21e outputs display data to the
application indicator 13 of each operation unit 10 based on the extracted setting according to
function, each application indicator 13 has functions assigned thereto. The name is displayed
(step 804), and the function of each operation unit 10 is switched to A (step 805). For example,
the operation panel is as shown in FIG. Note that the display on each operation unit 10 is A-1 or
A-2, etc., for example, by differentiating the multi-stage operation units 10 in the same channel
or by dividing the function of A into different operations. The purpose is to distinguish ones
assigned to the unit 10, etc. However, the method of distinction and the manner of display in
such a case are free, and may be a desired mode set by the user.
[0026]
In this state, when the encoder 12 of the operation unit 10 in a specific channel is operated, the
adjustment parameter inputted thereby is identified in the input signal processing unit 21 a of
the control unit 21 and extracted by the setting extraction unit 21 d Since the control signal
output unit 21e outputs the control signal of the function corresponding to A of the operated
operation unit 10 to the sound processing unit 40 based on the set function setting (step 807),
the sound processing unit 40 The sound of the corresponding channel is adjusted based on the
input control signal.
[0027]
To switch the function assigned to the operation unit 10 to another function, for example, when
10-04-2019
9
the button B displayed on the touch panel 30 is selected (step 808), the function setting
corresponding to the button B is extracted in the same procedure as described above Therefore,
as shown in FIG. 4, the function name is displayed on the application display 13 of each
operation unit 10, and the function corresponding to B can be adjusted by the operation of each
operation unit 10 (steps 802 to 807). .
[0028]
Next, a process of switching the user to a function set for each scene set in advance according to
the production stage will be described.
That is, when the user selects the Macro 1 button on the touch panel 30 (step 808), the input
signal processing unit 21a in the control unit 21 identifies that the selected button Macro 1 is a
button of the function set by the user. The switching control unit 21c determines that there is a
switching request to the function corresponding to Macro 1 (step 802).
Then, the setting extraction unit 21 d extracts the setting for each scene corresponding to the
button Macro 1 from the setting for every scene storage 22 b in the memory 22 (step 809).
Then, when the control signal output unit 21e outputs the display data to the application display
13 of each operation unit 10 based on the extracted function setting, the names of the functions
allocated to each application display 13 are displayed. Is displayed (step 810), and the function
of each operation unit 10 is switched to the setting of Macro 1 (step 811). For example, the
operation panel is as shown in FIG.
[0029]
In this state, when the encoder 12 of the operation unit 10 in a specific channel is operated, the
adjustment parameter inputted thereby is identified in the input signal processing unit 21 a of
the control unit 21 and extracted by the setting extraction unit 21 d Since the control signal
output unit 21 e outputs the control signal of the function corresponding to the Macro 1 of the
operated operation unit 10 to the sound processing unit 40 based on the scene-specific setting
(step 807), the sound processing unit 40 is executed. In, the sound of the corresponding channel
is adjusted based on the input control signal.
[0030]
10-04-2019
10
Furthermore, when the production stage shifts and it is desired to switch the function to be
assigned to the operation unit 10, for example, when the button Macro2 displayed on the touch
panel 30 is selected (step 808), it corresponds to Macro2 in the same procedure as above. Since
the setting according to the scene is extracted, as shown in FIG. 6, the function name is displayed
on the application display 13 of each operation unit 10, and the function set in Macro 2 can be
adjusted by the operation of each operation unit 10. (Steps 802, 809 to 811, 806, 807).
The above processing is performed until the end of the operation (step 812).
[0031]
[Effects of the Embodiment] According to the present embodiment as described above, the
functions of the encoder 12 and the switch 11 are switched to the setting suitable for each
production stage separately from the setting to the preset for each function group. be able to. For
this reason, it is not necessary to frequently select and switch the button each time the operator
performs the adjustment operation at a specific production stage, and the operation load is
greatly reduced.
[0032]
For example, at an imminent production stage such as during broadcasting, high program quality
can be secured without delaying the adjustment operation with respect to sudden voice changes
of the performers. Furthermore, by registering in advance a dedicated scene setting for dealing
with a sudden situation, it is possible to easily call it and switch it, so it is possible to prevent a
broadcast accident in advance.
[0033]
Further, the set function is displayed as a button on the touch panel 30, and switching can be
performed simply by selecting this button, so that customization such as selection operation,
addition, and change by the user becomes very easy. Therefore, for example, each broadcasting
station and each studio can easily cope with different production stages (for example, recording
mode and the like), and settings according to the preference of the operator can be freely made.

If the number of registrations is large and the number of buttons to be selected is large, it may be
set so that page feed can be performed.
[0034]
Other Embodiments The present invention is not limited to the embodiments as described above.
For example, the adjustment function of the audio signal can be set to any adjustment function
that can be performed on an audio signal (whether digital or analog) converted to an electrical
signal, such as level adjustment, equalizer, filter, etc. is there. For example, even if a specific
adjustment function A is subdivided into A-1, A-2, etc., any one of them may be set to be able to
be selected sequentially according to the number of times the button A is selected by pressing or
the like. Good. Further, the number of channels to be set, the number of functions for each
channel, the number of operation units according to this, and the like can be freely increased or
decreased. Further, the implementation modes of the operation unit, the setting input unit, and
the selection unit are not limited to the switches, encoders, touch panels, and the like exemplified
above. Any input device available now or in the future, such as a sliding volume, a switch, a
keyboard, a mouse, a touch panel, etc., is applicable. Therefore, part or all of the operation unit,
the setting input unit, and the selection unit can be realized by a touch panel, or the selection
unit can be realized by a fixed switch.
[0035]
The layout of the display screen when the selection unit or the like is a touch panel can be freely
set including the size and the number of buttons corresponding to the function. The layout may
be freely set by the user. As a display device used as a touch panel or a usage indicator, any
display devices available now and in the future, such as LCD and LED, can be applied.
Furthermore, it is up to the user to register the setting for each scene according to the scene. For
example, different settings can be registered in chronological order as in the production stage
shown in the above example, or different settings can be registered depending on the installation
place such as a studio or a stage. It is also possible to register different settings for each operator
to use. That is, the "scene" in the present invention is a broad concept that means the situation to
be used. It is free to combine the setting according to function and the setting according to scene,
and it may be configured as a device in which all the functions of each operation unit can be set
by the user.
