Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic mixing apparatus for automatically producing sound effects during the production of software for televisions, radios, etc., especially during sports program competitions, and in particular to sound effects in sports broadcasting such as skiing. The present invention relates to an automatic mixing device for mixing and adjusting in real time the sound effects for TV broadcasting of sports competitions such as downhill competitions, jump competitions, speed skating, and track competitions, gymnastics competitions, soccer, etc.

Here, "mixing" means that voice inputs from two or more microphones or the like are switched by adjusting tone color, volume level, localization, etc., or are arbitrarily mixed, or each voice input is made. Means adjusting these volume level timbres and the like over time.

[0003]

2. Description of the Related Art Conventionally, in the production of sports programs, the sound related to the competition such as the sound of a competitor is picked up and mixed to produce the sound effect of the program as a sound effect (SE). Especially in winter sports, jumping, downhill skiing, spinning, luge, bobsled, and other long-time high-speed competitions require the use of 30 to 40 sound pickup microphones and follow the athletes. It is necessary to perform mixing at an early timing according to camera switching and the like. In addition, in track and field athletics, about 10 microphones are set on the circumference of a 400m track and mixing is performed according to the movement of athletes.
In soccer broadcasting, we set dozens of microphones around the soccer field, and quickly switch between these microphones according to the movement of the ball to mix.

As described above, in the conventional SE processing for mixing the sports competition relay in which it is necessary to surely follow the microphone in accordance with the movement of the player and in accordance with the timing of switching the camera, it is necessary. The microphones are laid to the main mixing position for long distances, the microphone cables are laid, and the sound is input, and the sounds of those microphones are mixed with the hands of the mixer (mixing operator) while monitoring the TV monitor and adjusting to the screen. There is.

Since the current mixing is based on such manual mixing, in order to perform mixing in response to quick screen switching, instead of manually switching the microphone, a camera tally is relayed. It is taken out of the car and the microphone is switched by this camera tally signal (a signal for informing that the camera is currently broadcasting). Currently, the tally control device that performs this microphone switching sets one input channel for one microphone, sets a tally that controls this channel in advance, and turns on and off this mike channel by the tally signal. It reduces the burden on the mixer. Since the role of conventional equipment is to support manual mixing,
Until now, I have not allowed me to take the form of mixing multiple microphones with one tally signal.

A remote control mixing amplifier is also currently being developed. This is a control device placed at the mixer's hand to input a voice signal from a microphone to a remote device installed at a remote place. It is designed to be remote-mixed by one's own hands. This is to be done by the mixer itself, and does not automatically perform the mixing operation.

A control signal used for automatic mixing in a studio such as a computer mix includes a continuous MIDI (Musi) MIDI signal that includes continuous SMPTE time code, tuck pulse, and control information.
cal instrument digital interface) signals, etc., but detection signals and tally signals output from position detection sensors that are discontinuous and come arbitrarily are not used for the purpose of mixing.

As for the automatic mixing system, a computer mix system compatible with studio production is generally in operation. It records mixing control data of each audio input channel at the time of rehearsal with SMPTE time code or tuck pulse as the time axis, controls each microphone channel by these data at the time of production, and has the same time axis as at the time of rehearsal. On the other hand, the exact same mixing operation is reproduced. In the work (generally called MA work) in the audio editing system using the multi-track recorder, the video and S
These systems are also used for synchronizing sound with an MPTE signal to create a sound suitable for an image. In all of these cases, the time axis signals for control are recorded by setting the mixing parameters based on a reference time signal with a fixed time axis such as a continuous time code. To reproduce the parameters. Therefore, in these conventional cases, there is no fluctuation on the time axis. Further, these conventional examples do not support automatic mixing corresponding to real-time sports relay program production based on a detection signal and a camera tally signal fetched from the outside.

Furthermore, currently necessary times such as the elapsed time of sports competition are generally measured by using signals having a function of measuring time. These signals are tally signals for automatic control of mixing. The system for automatically performing mixing such as volume control using the unit time output together as a time axis has not been proposed yet.

[0010]

In conventional sports broadcasting, SE using many microphones, especially about 40 microphones, is used.
In the case of a ski downhill competition where (sound effects) must be collected and mixed, as an example, a destination mixing house is set at the start point and a main mixing house is set at a goal point 3 km away. The mixed output from the house etc. is received, and the mixing of all the courses is performed by combining them, and it is output as the SE of the whole competition. In such a case, it is necessary to have at least two people, including the mixer in charge of the destination mixing and the main mixer, and according to the competitors who pass at a high speed,
In addition, it is a difficult task to manually mix the necessary microphones according to the changing TV screen. Also, laying these microphone lines in the snow about 3km from the start to the finish is also difficult.

There is a limit to the microphone operation that can be dealt with in the manual mixing of the mixer. Especially, it is difficult to perform mixing operation at a high speed. Therefore, as mentioned above, there is a tally control device (auto fader) that can turn on and off one microphone with the camera tally.
This is just a microphone switch, and so-called mixing such as level adjustment is not possible. Also, the detection signal that can be input to this is only the camera tally. The microphone cable must also be installed over a long distance from the main mixer location to the sound collection point.

[0012] In an example such as a soccer game, the SE sound of a player in the field, the movement of the ball, etc. is picked up by a sound pickup microphone placed around the field. Also in this case, each microphone is input to the mixing amplifier and the mixer manually mixes. In the soccer game, the balls and players move quickly, and manual mixing often cannot keep up with the speed of the game.

The present invention has been made in view of the above points, and an object thereof is to automatically mix the sound of a microphone installed in a stadium to collect a sound effect, so that the human hand does not need to.

In a section (referred to as a tally section), as a unit time measuring sensor for measuring a unit time Δt of a player who passes the point A, for example, two infrared sensors A and B are used.
Are installed at intervals of about 50 cm to 1 m, and the time taken for the athlete to pass between them is measured. That is, the pair of pulse signals generated from the sensors A and B when the player passes between the sensors A and B includes time information. Therefore, at the frequency (unit time) of this passing pulse, as shown in FIGS. 6A and 6B, a time axis signal is generated, and the time axis of this time axis signal (time pulse) A voice control amount (mixing parameter) is stored.

It is assumed that there are several microphones to be subjected to mixing control, which are arranged in this T1 section. Therefore, the mixing operator (mixer) must be installed in relation to the location of the sensor and the placement of the microphone.
The new know-how is how to set these to obtain the optimal mixing.

As the above unit time measuring sensor, an ultrasonic sensor may be used in addition to the infrared sensor. False signals generated due to factors other than the passing of the player can be eliminated by the tally processor 502. Further, if an athlete uses an ID number such as an ID transmission card having a transmission function in the future, the instantaneous speed can be detected by receiving this ID signal with a radio wave sensor. Time pulses can be easily generated from this instantaneous velocity signal. By reading the sample data (mixing parameter) with the time signal that changes depending on these passing players,
Sample data can be adapted and reproduced for these passing players. Note that this time signal is valid only in the corresponding tally section.

For example, assuming that the speed of player A is slower than the speed of player B, the passing unit time Δt of player A passing through point A is the passing unit time Δt1 of player B passing through point A as well. Longer than. Therefore, the frequency of the time-axis signal of player A becomes lower than the frequency of the time-axis signal of player B. In this way, the frequency of this time-axis signal varies depending on the passing speed of the player. Then, by reading the mixing parameters of the player A on the time axis created by the unit time of the player B, the mixing control is performed according to the speed of the player B. The characteristic of this control is that the time of the player who always passes, that is, automatic mixing is performed not for a fixed time axis signal (frequency signal) such as SMPTE time code, tack pulse, or MIDI signal but for a fluctuating time axis signal. Especially.

FIG. 7 shows the details of the structure for automatically mixing according to the time axis of the corresponding tally section by the detection signal including the unit time information described above. In this example, when a detection signal including time information arrives at an input terminal of the detection signal input unit 302 from a unit time detection sensor having a function of detecting a passing time of a passing player, etc., a tally setting unit of a destination unit In the system tally generating unit 3031 of 303, Δ
Using the T separation unit 3032 and the time pulse generation unit 3033, a time pulse is generated based on the unit time (instantaneous time) ΔT of this time information, and the generated time pulse is T1.
Is sent to the main body from the tally output unit 3035 as a system tally signal with the identification number (ID) added by the ID setting unit 3034.

When this system tally signal is received via the tally processor 502 and the tally output unit 504 of the main unit, the mixing setting unit 508 sets the input channel of the audio signal input unit of the destination unit controlled by the tally signal. Using the mixing parameter setting unit 509 for the set input channel of the audio signal input unit, a mixing parameter is set based on the time axis of the system tally signal, and the audio input unit mixing is set in the tally section. The change in the mixing parameter with respect to is stored in the storage device unit 511. Next, the mixing parameter setting unit 509, to which the input channel of the voice input unit controlled by the tally signal is assigned, is based on the unit time of the player who next passes the mixing parameter stored in the storage unit 511. The generated time pulse is used to reproduce the read-out mixing. As a result, the mixing parameter of the player who passed first can be adapted to the player who passed next, and the automatic mixing can be reproduced. That is, the change of the mixing parameter with respect to the time axis of the mixing control of the previous player on the T1 tally is read on the time axis of the T1 tally section generated by the next player,
By using the parameters of this player's automatic mixing, it is possible to perform automatic mixing that matches the movement of the player. This time pulse is different for each passing player, and the time axis of this pulse is a variable time axis. In addition, the mixing to be adapted is also reproduced corresponding to the speed of the players.

(Second Embodiment) In the second embodiment of the present invention, as shown in FIG. 8, a position signal (camera) obtained by analyzing the moving position of a subject such as an athlete with two cameras. (Positional information) is used as a detection signal for controlling the automatic mixing apparatus. That is, the two cameras installed in two places are aimed at the point A where the object is, and the object is photographed by the two cameras. Information is calculated, and the calculated position information is output to the destination section as a position signal.

The overall system configuration of this embodiment is shown in FIG. The destination unit 300-2 controls the mixing of the corresponding voice input signal by using the position signal. The main unit 500 sets the parameters of the audio signal input unit of the destination unit. The structure of this delivery part is shown in FIG. 10, but it is the same as the structure of FIG. 4 of the first embodiment. The structure of the main body is similar to that shown in FIG. 5 of the first embodiment, and therefore its explanation is omitted.

(Third Embodiment) In the third embodiment of the present invention, as shown in FIG. 11, the entire stadium is shown by a touch panel, and the screen of the touch panel is touched by a finger of a mixing operator or a baton. X and Y of the screen generated by
Predetermined position information is calculated from the coordinate information of 1., this position information is output as a position signal, and this position signal is used as a detection signal for controlling the automatic mixing apparatus. That is, for example, in the case of a soccer game, as shown in FIG. 11, the board surface of the touch panel is divided into squares, and a tally number is given to each of the squares as the position information to control the microphones related to the location by mixing. ,
I'm ready for automatic soccer mixing. This example can be applied to competitions such as rugby, hockey, and ice hockey.

The overall system configuration of this embodiment is shown in FIG. The destination unit 300-3 uses the position signal (tally number) input from the touch panel device 600 through the interface 610 to perform mixing control of the corresponding audio input signal. The main unit 500 sets the parameters of the audio signal input unit of the destination unit. The configuration of this delivery part is shown in FIG. 13, but it is the same as the configuration of FIG. 4 of the first embodiment. The structure of the main body is similar to that shown in FIG. 5 of the first embodiment, and therefore its explanation is omitted.

(Fourth Embodiment) In the fourth embodiment of the present invention, as shown in FIG. 14, the detection signal for the operation of the system is a position signal based on image information. Image display device 7
00 recognizes the position of the object from the image information of the image of the object and outputs the position information. This position information includes X and Y coordinate information and is sent to the destination section as a position detection signal tally through the interface 710. In this example, the sound pickup microphone can be automatically controlled by, for example, key-outputting the ball position based on the image signal.

The entire system configuration of this embodiment is shown in FIG. The destination unit 300-4 controls the mixing of the corresponding audio input signal by using the position detection signal tally input from the image display device 700 through the interface 710. The main unit 500 sets the parameters of the audio signal input unit of the destination unit. The structure of this destination part is shown in FIG. 16, but it is the same as the structure of FIG. 4 of the first embodiment.
The structure of the main body is similar to that shown in FIG. 5 of the first embodiment, and therefore its explanation is omitted.

(Fifth Embodiment) Next, FIG. 17 and FIG.
FIG. 8 shows an example of the internal configuration of the tally processor 502, the tally logic setting 503, the mixing parameter setting unit 509, and the output processor unit 510 of the main body as the fifth embodiment of the present invention.

As shown in FIG. 17, as an example, the tally processor 502 analyzes the input port information, the identification number, and the frequency (unit time Δt) of the input tally signal, the tally input analysis section 5021 and the tally logic setting section 503.
A comparison logic unit 5022 that eliminates false tally and determines priority based on the above determination, and a tally generation unit that generates a tally signal output timing from the tally signal and the tally signal Δt from the comparison logic unit and outputs a system tally. Fifty
23 and.

The detection signal input to the detection signal input section 302 of the destination section 300 becomes a tally signal in the tally setting section 303 and is sent to the tally input analysis section 5021 of the main body section 500. The tally input analysis unit 5021 detects the identification number (also called tally ID) of the input tally signal,
It is displayed on the display unit 51 through the tally logic setting unit 503.
The identification number of the tally signal that has been sent to No. 2 is displayed and is also sent to the comparison logic unit 5022. At this time, the display unit 512 displays not only the identification number of the incoming tally signal but also the input port information input to the destination unit,
It serves as a reference when setting the tally logic.

For example, when the game progresses in a certain direction,
Detection signals output from devices such as cameras and detection sensors installed on the competition course that detect the progress position of the athlete's competition are sent from each destination according to changes in the athlete's position. The camera tally and the like are not always input to the detection signal input section 302 of the destination section in the order in which the athlete progresses in the competition. Therefore, in order for the system to correctly recognize the arrival order of tally signals, it is necessary to set the arrival order based on the tally ID (recognition number). In addition, because of the nature of the detection sensor, it is necessary to eliminate the false tally generated by passing other than the player. Therefore, the logical setting for this is required. In addition, it is necessary to give priority to the tally signal, but this is because it is required to mix sound effects matched to the screen for TV program production, so it is better than the detection sensor signal generated by the passage of the player. In addition, the camera tally signal is given priority, that is, a specific detection signal is given priority, and when that tally signal is output, it is prioritized over other tally signals and is set by the tally signal. This is because it is necessary to have a function for giving priority to. The tally logic setting unit 503 described above is for performing such logic settings as false tally elimination and priority setting in a predetermined manner.

However, when the device for inputting the position information of the competition of the athlete is a touch panel or the like, the tally signals sequentially arrive at random, so the arrival order setting in this case is random setting, but Since the signal is forcibly generated artificially by the operation, a false tally or the like does not occur, and thus the above logic setting (logic setting) is not necessary. Also, in the example of repeatedly orbiting a certain course, by setting the priority given to each camera tally signal by the sensor detection signal,
Mixing that matches the screen is possible. In this way, the tally logic setting unit 503 enables the tally logic to appropriately perform mixing according to the characteristics of the competition.
Is set to switch.

The tally signal output from the tally input analysis unit 5021 is input to the comparison logic unit 5022. In the comparison logic unit 5022, execution of the priority set by the tally logic setting unit 503 and execution of the false tally signal are performed. Exclusion or the like is executed, and is further generated as a system control tally signal for controlling the system by the tally generation unit 5023,
The system control tally signal is distributed through the tally output unit 504.

In addition to this, when a radio wave sensor for detecting the player's bib ID signal is used, the tally input analysis unit 5021 analyzes the player's ID signal to obtain this ID.
The tally logic including the signals is selected, the priority is also set, and the comparison logic unit 502 is set by the tally logic setting to sequentially output from the tally logic setting unit 503.
By selectively outputting these tally signals from the tally signals input to 2, the player can be tracked and mixing control can be surely performed.

FIG. 18 shows an example of the configuration of the mixing parameter setting section 509 and the output processor section 510 of the main body section. This example is a configuration example in which the number of voice inputs such as microphones at the destination is greater than the number of channels of the mixing parameter setting unit 509. The mixing parameter setting unit 509 includes a mixing parameter setting unit 5091 for each channel, a parameter setting unit control unit 5092, and a tally signal time axis separating unit 5093. The output processor unit 510 is a process unit 5101 for each channel.
And an output selection unit 5102. In addition, the storage unit 51
4 is a memory 5 for the parameter setting section for each channel
141 and a memory 5142 for the mixing setting unit.

The mixing setting section 508 sets the audio input channel of the destination section for which mixing control is performed by the tally signal, and stores the setting result in the memory 5142. This setting designates the audio signal input units 306 of all the destinations to be controlled by the tally signal. Each mixing parameter setting unit 5091 is a unit that sets a control parameter related to the tally signal of the audio input channel of the destination set by the mixing setting unit 508. Specifically, the mixing parameter setting unit 5091 sets the audio signal of the input microphone or the like. Generates mixing parameters such as ON / OFF, volume, etc. These settings are written in and read from the corresponding memory 5141 as needed. These set amounts are displayed on the display unit 512 to support automatic mixing. The setting amounts of these mixing parameters are output to the process unit 5101 in synchronization with the arrival of the tally.

In the process unit 5101, the setting amount of the mixing parameter is corrected to a control signal for controlling the destination unit, and the output selection unit 5102 controls the voice input unit of the destination unit related to the tally for which the mixing is set. Output a signal. When outputting these control signals, the output selection unit 5102 outputs the control signals, and the audio signal input units 306 of the plurality of destination units to which mixing is set by the tally signal.
, It is possible to output each parameter at the same time. Therefore, the output selection unit 5102 has a matrix function that can be sequentially switched and selected by the tally signal according to the mixing setting.

The tally signal time base separation unit 5093 of the mixing parameter setting unit 509 separates and extracts the time base signal generated by the unit time, generates a mixing parameter control signal according to the time base of the tally signal, and outputs it. It is used to The parameter setting unit control unit 5092 sequentially assigns mixing parameter setting channels to the audio input channels of the audio input unit of the destination unit, which are mixing-set by the tally signal, generates parameters, or stores parameters stored in advance. Read from memory,
It has a function that can be updated as needed through the mixing parameter setting channel.

(Sixth Embodiment) FIG. 19 shows a sixth embodiment of the present invention.
As another embodiment, another example of the configuration of the mixing parameter setting unit 509 and the output processor unit 510 of the main body will be shown. This example is a configuration example in which the number of voice inputs such as microphones at the destination and the number of mixing parameters of the mixing parameter setting unit 509 are the same, which is a simpler system than the configuration of FIG. 18 described above.

The mixing setting section 508 sets the audio input channel of the destination section to be mixing-controlled for the tally signal. Since each mixing parameter setting unit 5091 corresponds to each audio input channel of the destination unit, the mixing parameter setting unit 5091 corresponding to the audio input channel of the destination unit set by the mixing setting unit 508 due to the arrival of the tally signal. The mixing parameter set in step 1 is output to the destination unit as a control signal of the audio input channel of the corresponding destination unit via the process unit 5101 and the output selection unit 5102.

(Seventh Embodiment) FIG. 20 shows the entire construction of the seventh embodiment of the present invention. The present embodiment is an example of a case where 40 or more sound pickup microphones are used in a ski downhill competition or the like. The internal configurations of the delivery section and the main body section are the same as in the first embodiment.

Each of the plurality of destination parts 300A to 300E inputs the detection signal of the sensor for detecting the passage of the player, the detection signal of the sensor for measuring the instantaneous speed, the camera tally signal, etc. Input audio signals at the same time. About eight microphones and eight detection signals can be input to each of the destination parts 300A to 300E, and the efficiency of installation can be improved by installing these destination parts at various places on the competition course. These destinations are connected to the main body 500 by an optical cable 410 via the optical signal interfaces 400A to 400E, respectively. Body 50
In 0, the tally signals coming from these optical cables 410 are integrated, the tally order is set, the camera tally of the necessary camera or the like is set to the priority, the guard against the false tally is set, and the sound from the microphone is output by each tally signal. Control the signal and apply automatic mixing.

(Eighth Embodiment) FIGS. 21 to 24 show an eighth embodiment of the present invention. In this embodiment, as shown in FIG. 21 and FIG. 22, the output signals of 11 sound effect microphones, 5 TV cameras, and 6 detection sensors are input to two destination parts 300A and 300B in a ski downhill competition. Then
This is an example of processing by the main body unit 500. 21 to 2
The symbols and contents in 4 are as shown in the table below.

[0080]

[Table 1] M1, M2, M3, ...: SE sound pickup microphone Camera 1, camera 2, camera 3, ...: Camera for shooting competition S1, S2, S3, ...: Detection sensor tc1, tc2, tc3, tc4, 5c5: Tally signal of camera ts1, ts2, ts3, ts4, ts5, ts6: Detection signal from detection sensor T1: Tally signal generated from tc1 T6: Tally signal generated from tc3 T2: Tally signal generated from ts1 T7: Tally signal generated from ts4 Tally signal generated from T3: tc2 Tally signal generated from T8: tc4 Tally signal generated from T4: ts2 Tally signal generated from T9: ts5 Tally signal generated from T5: ts3 T10: tc5 From Tally signal generated T11: Tally signal generated from ts6 In FIG. 23, (A) is a tally signal output from the output unit 1 of 300A, and (B) is a tally signal output from the output unit 2 of 300B. It indicates over signal and (C) and (D) shows the timing of the arrival pattern with respect to time of the camera tally signals and sensor detection tally signals arriving at the tally processor 502 of the main body portion. In television broadcasting, it is required to mix sound effects suitable for the screen. Therefore, it is not always necessary to switch cameras according to the progress of the competition. Therefore, in the tally logic setting of the main body unit 500, it is necessary to give priority to the camera tally signal over the detection signal tally from the detection sensor. As shown in FIG. 23, the flow of the competition is ts1, ts2, ts3, ts4, ts5,
Since it proceeds while generating a detection signal with ts6, if there is no screen in a radio broadcast, etc., automatic mixing can be operated according to these flows. When the camera takes a picture of the start, the voice also needs the start voice, in which case the camera tally tc1 comes in this example. At this time, if priority is given to the camera tally, the tally processor 502 ignores ts6 and activates the operation of the sensor tally ts1 included in tc1.
Similarly, when tc2 arrives, ts2, ts3, tc3 ts4, tc4
Activates ts5 and tc5 activates ts6. With this setting, the camera tally can be complemented by the detection sensor tally signal. This is the case for such competitions
The coverage of one camera is 50m-80 of the course.
This is because the tally signal from the camera alone cannot sufficiently collect the sound.

The output signal from the detection sensor may be output from a factor other than the player, but in order to eliminate this, in order to eliminate this, the next tally signal from the arrival order of the sensor tally signal When signals other than the arrival order of the signals arrive, the tally logic setting unit 503 performs logical setting to ignore these signals, and the tally processor 502 eliminates them.

FIG. 24 shows the main body portion 500 in this embodiment.
18 is used as the mixing parameter setting unit 509 of FIG. 18, and the timing when the mixing setting unit 508 sets the mixing of each microphone input to the destination of each tally signal is shown. Tally 1 (T
For the settings from 1) to tally 11 (T11), the mixing parameter setting unit 509 sets each mixing parameter. In the case of such 6 channels as the mixing parameter setting channels, the setting channels of the respective mixing parameter setting sections 509 are assigned to the input channels of the destination section at the incoming tally timing as shown in FIG.
The set parameters are output to the output processor unit 510. The tally timing also controls the output processor unit 510, and sequentially outputs a control signal necessary for the control unit of the audio input channel of the destination unit which is set to be mixed by the tally. For reference, an example of the relationship between the mixing setting and the mixing parameter setting in this example is shown in the table below.

As described above, according to the present invention,
Since multiple detection signals such as sensor detection signals are effectively used as system tally signals, which are timing signals for mixing control, and multiple audio signals are automatically mixed, it can be deployed at high speed. High-quality sound effects can be reliably mixed in sports competitions, and high-quality sound effects that match the TV screen can be efficiently mixed.

Further, according to the present invention, a unit time measuring function is added to the detection signal generating section for generating a detection signal when a player passes by, so that the detection signal can include time information. A time axis signal is generated based on the signal, and the mixing parameter according to the time change of the corresponding tally section is stored by this time axis signal, and the detection including the unit time generated by the passage of the next player is detected. By generating a new time axis signal from the signal and reading the mixing parameter for the previous player along this time axis and applying mixing control,
Even in an example such as a downhill competition, it is possible to capture the sound of a plurality of microphones installed near each destination part in each destination part that is gathered in about 5 places, and to improve the efficiency of construction. Fast mixing operation can be surely performed unattended.
In addition, this makes it possible to reliably perform sensor tally such as quick microphone follow-up such as F1 race, microphone switching, and localization operation, which is difficult with manual mixing by a mixing operator. Furthermore, in ski downhill competitions,
There are about 40 sound effect pickup microphones along the course, but conventionally, about 3 mixing operators were attached to these mixings, but the apparatus of the present invention can cope with about 1 to 2 people. Also, by effectively using the outgoing part, the setup of the microphone cable etc. can be simplified.

Further, in the present invention, each zone set on the touch panel simulating the competition field is
Since the detection signal can be output by simply touching the touch panel and the detection signal can be automatically mixed, the automatic mixing in a soccer game can be surely dealt with.

Further, in the present invention, if the ID calling card is used for the player's bib number in the future, it becomes easy to detect the passing position of the player, and the detector can be incorporated in a microphone, for example. . As a result, many mixing microphones were conventionally mixed manually, which required a large number of mixing operator personnel. However, it is possible to improve the efficiency of these, the efficiency of setup, and reliable mixing, so high quality can be expected. It has a very wide range of uses in the field of sports broadcasting such as winter sports, athletics, swimming, soccer, rugby, hockey, speed skating, car racing, cross-country, marathon, etc.
