Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, an automated mixing console device in which position information of a fader is stored in advance and the level of an audio signal by the fader is automatically adjusted based on the stored position information. The present invention relates to a control device for a mixing console device that is suitable for use in.

[0002]

2. Description of the Related Art Conventionally, a mixing console for adjusting the levels of a plurality of audio signals has been widely used for both general and commercial use.

The mixing console device will be briefly described. The mixing console device has a plurality of audio signal input terminals and a plurality of faders corresponding to the input terminals, and an input is made by changing the position of the fader by an operator. While changing each level of the audio signal, the localization of the audio signal whose level has been changed is divided into left and right by a pan pot volume, etc., so that a plurality of finally input audio signals are output in two-channel stereo. It was done.

By the way, the operation of the fader is very difficult, a considerably skilled operator is required, and even a skilled operator often rehearses the operation of the mixing console device. In other words, even a skilled operator cannot always perform the best operation in production, for example, recording, online editing, etc. Therefore, it is necessary to preliminarily prepare the fader position to some extent.

Conventionally, in order to solve such a problem, the position of a fader operated by an operator is stored, and at the time of actual operation, the fader is automatically moved based on the stored position information of the fader. A mixing console device having a device has been proposed.

In this mixing console device, for example, when adjusting the audio in synchronization with the video, V
The video signal generation source such as TR is set in the playback (PLAY) state, the position of the fader operated by the operator is stored in association with the time code from the VTR, and the VTR is also in the playback state in the actual production. By reading the time code from the VTR or the like and comparing the read time code with the stored time code, the fader position information related to the stored time code is referred to, The fader is automatically moved by a motor or the like based on the referenced fader position information.

[0007]

By the way, a problem in the case where the audio signal is adjusted and output or recorded according to the image is that the operation speed of the fader by the operator is limited.

For example, when the image is obtained by photographing a city, if noise is mixed, it is necessary to cut the noise.

Of course, in order to cut this noise, only the noise portion should be cut, but operations such as lowering the sound at a certain point and raising it at a certain point cannot be performed within one frame of video.

That is, in the conventional control device of the mixing console device, the fader operation is performed by the operator when the VTR or the like is in the reproduction state, so that it is impossible to cut only the noise, and thus the conventional operation is not possible. In the above, all the audio signals of the noisy frame are cut.

In this example, the case of cutting the noise of the sound of the image and the sound obtained by photographing the city is explained, and thus the sound of the frame is cut in order to cut one noise in this way. If you cut
The ambience of the city disappears at all in that frame. For example, if this is a broadcast material, the ambience of the city may be for a moment (when one frame of audio has been cut), or for a while (a few frames of audio have been cut). The interruption causes a disadvantage that the viewer cannot perform high-quality broadcasting.

The present invention has been made in consideration of the above points, and it is an object of the present invention to propose a control device for a mixing console device which can obtain good sound by reproducing the operation of the fader even in a short time. To do.

In the NTSC system, SMPTE,
In the PAL system, the time code is EBU. Also, the above-mentioned LTC is used when the video signal source such as the VTR is in the reproduction mode of high speed reproduction or normal reproduction speed.
The ITC is used in the jog or still mode, for example.

As shown in the figure, the automation device 5 comprises a transport generation section 6 and an automation controller 7, and the automation device 5 can have a structure as shown in FIG.

The transport generation section 6 is composed of, for example, the configuration and software shown in FIG. 2, and the transport generation section 6 turns on / off the switch 8 and a sync signal generation source (VTR, sync generator, etc.) not shown.
Select LTC or VITC from LTC reader 2 or VITC reader 4 based on, and also interpolate and stop LTC or VITC (STOP), shuttle (speed change playback), jog (JOG), servo lock, or playback (PLAY). Etc. are generated based on the time code comparison result.

On the other hand, the automation controller 7 stores the fader position data indicating the fader position of the moved mixer main body 9 when storing the fader position data based on the transport data and the time code from the transport generator 6. When performing a mixing operation with the stored fader position data, the motor is controlled based on the stored fader position data and the time code, and the fader of the mixer body 9 is automatically moved.

Next, an example of the internal configuration of the automation device 5 will be described with reference to FIG.

As shown in FIG. 2, in this example, the automation device 5 connects a bus (consisting of an address, a data and a control bus) 11 to the CPU 10, and the bus 11 includes, for example, the above-mentioned transport generator. A ROM 12 storing software for operating 6 and software for operating as the automation controller 7 is connected, and for work of various operations by these software, for example, time code data and fader position data described later are stored. A RAM 13 as a memory for storing is connected, an output port 14 for outputting a control signal for driving a fader is connected, and a control signal for driving a fader is converted to an analog signal at this output port 15 D -Connect the A converter 15 and connect this DA converter. Connect the motor 16 of the fader driven converter 15, connected to the rotary encoder 17 for detecting the rotation angle of the motor 16 to the motor 16, the input port 18 the output side of the rotary encoder 17
It is configured by connecting to the bus 11 via. Incidentally, the D-A converter 15, the motor 16 and the rotary encoder 17
Is provided for each of the plurality of faders of the mixer body 9 shown in FIG.

When a volume is used as the detecting means for detecting the position of the fader, an A-D converter for converting the output of the volume into a digital signal may be provided in the preceding stage of the input port 18.

Here, the case where the RAM 13 is provided with an area for storing the time code and the above-mentioned fader position data will be described with reference to FIG. A memory for the area may be separately provided.

In FIG. 3, reference numerals 13a to 13c denote storage areas for time code and fader position data FD, respectively. Here, when there are multiple input audio signals (piano, bass, drums) corresponding to the video signal, the fader position corresponding to the set fader position when the level of each input audio signal is set by the fader. It shows how data is stored corresponding to a time code supplied from a VTR or the like.

The LTC reader 2 or VIT shown in FIG.
LTC or VIT from VTR etc. by C reader 4
When C is read and the fader for adjusting the input voice signal of the piano is moved by the operator at that time, the rotation angle signal from the rotary encoder 17 shown in FIG. 2 is supplied to the CPU 10 via the input port 18, As a result, the time code at that time (LTC or V
ITC) and fader position data FD (piano) are stored as shown in area 13a of FIG.

Next, when the LTC or VITC from the VTR or the like is read by the LTC reader 2 or VITC reader 4 shown in FIG. 1 and the fader for adjusting the input audio signal of the base is moved by the operator at that time, The rotation angle signal from the rotary encoder 17 shown in FIG. 2 is supplied to the CPU 10 through the input port 18, whereby the time code (LTC or VITC) and fader position data FD (base) at that time are shown in FIG. It is stored as shown in area 13b.

Next, when the LTC or VITC from the VTR or the like is read by the LTC reader 2 or VITC reader 4 shown in FIG. 1 and the fader for adjusting the input audio signal of the drums is moved by the operator at that time, The rotation angle signal from the rotary encoder 17 shown in FIG. 2 is supplied to the CPU 10 via the input port 18, whereby the time code (LTC) at that time is output.
Or VITC) and fader position data FD (base)
Is stored as shown in area 13c of FIG.

That is, the RAM 13 sequentially stores the time code and its position when the fader is moved by the operator, that is, the fader position data. At the time of reproduction, the fader position data is selected based on the time code stored in the RAM 13 and the time code supplied from the VTR or the like, and the CPU 10 shown in FIG. 2 is selected based on the selected fader position data.
Supplies a control signal to the DA converter 15 via the output port 14. The control signal supplied to the DA converter 15 is converted into an analog signal here and supplied to the motor 16 for driving the motor 16. By driving the motor 16, the motor 16
The fader connected to is moved, and the level of the input audio signal is changed according to the image.

In this example, a very short voice such as a voice in one frame, for example, noise can be cut while leaving one frame or several frames of voice. . As described above, when the operator performs the mixing operation for generating the fader position data, it is impossible to perform the fader operation in a short time. Therefore, in this example, the VTR or the like which is the image generation source is used. The fader position data can be generated even in reproduction other than the normal reproduction state, such as slow or jog mode.

A sync signal (so-called video sync) Vsync which is not shown in FIG. 4 is shown, and as shown in FIG.
In this example, the time codes TC1, TC2, and TC are passed after a predetermined time t has elapsed from the rising of the synchronization signal Vsync.
Read 3, ...

The CPU 10 shown in FIG. 2 sequentially compares the time codes TC1, TC2, TC3, ... From the LTC reader 2 or VITC reader 4 shown in FIG. Detects the playback mode of.

For example, if the time code TC1 and the time code TC2 are the same, the CPU 10 determines that the reproduction mode is slower than the normal reproduction speed, and the time code TC2 is "1" (time If the time code TC2 is smaller than the time code TC1 by "1", it is determined that the normal reproduction speed is the normal reproduction speed in the normal direction. It is judged that the reproduction mode is set, and if the value becomes any other value other than 8 times in succession, it is judged that the reproduction is stopped or the high speed reproduction is in the reverse direction, and the judgment result is generated as a flag. Based on this, the normal mode and slow mode, which will be described later, are set.

In this example, the normal mode is selected when it is determined that the reproduction mode is the normal reproduction speed, and the slow mode is selected when the reproduction mode is slower than the normal reproduction speed. To do. The normal mode here means a mode in which the fader position data and time code are not stored in the RAM 13 shown in FIG.
The slow mode means storing fader position data and time code data in the RAM 13 shown in FIG.

Therefore, in this example, both normal and slow modes are set when the flag indicates a reproduction mode at a normal reproduction speed, and the flag is either normal or slow for stop, fast forward and slow reverse. When the flag is slow forward or still, the slow mode is set without setting the mode.

Therefore, if the operator can perform the fader operation during the reproduction at the normal reproduction speed, the operator can use the slow mode during the reproduction at the normal reproduction speed, and cannot perform the fader operation during the reproduction at the normal reproduction speed. In the slow or slow forward reproduction, the faders can be operated in slow mode to obtain fader position data.

Here, the position of the fader and the level change of the audio signal depending on the position will be described with reference to FIGS. FIG. 5 is an explanatory diagram for explaining the position of the fader, and FIG. 6 is an explanatory diagram for explaining the level change of the audio signal corresponding to the position of the fader.

As shown in FIG. 5, paying attention to the operation of one of the plurality of faders of the mixer body 9 shown in FIG. 1, the state A (the level of the audio signal is raised first according to the time T). State), then state B (state in which the level of the audio signal is lowered), and finally state C (state in which the level of the audio signal is raised again), the audio signal whose level is adjusted by this fader is As shown in FIG. 6, first, the level is high at the position of the point PA, decreases at the next point PB, and returns to the original level again at the position of the next point PC.

As described above, for example, in the case of cutting noise, in order for the operator to move the fader as described with reference to FIG. 5 and FIG. It may be slower, for example, still or slow playback.

Now, the setting of the fader position by the operator will be described with reference to FIG. In FIG. 7, IN is an IN point (audio editing start point), OUT is an OUT point (audio editing end point), and a fader indicated by a broken line at the IN point IN means lowering the fader at the IN point IN, A fader indicated by a broken line at the position of the point OUT means raising the fader at the out point OUT.

In this example, the normal mode is set up to the IN point IN, the slow mode is set between the IN point IN and the OUT point OUT, and the normal mode is set after the OUT point OUT.

The operator first sets the VTR or the like in the still state, and thereafter searches for the in point IN and the out point OUT with the jog dial dial or the like. That is, the audio signal of the image is heard after the still state is entered, noise is mixed, or the level is checked.

If the in-point IN is found, the operator specifies here that it is the in-point IN. In this case, the CPU 10 shown in FIG. 2 sets the slow mode. Then, when the fader is lowered by the operator as shown in FIG. 7 (positioned to lower the level), the time code obtained at this IN point IN and the fader position data are stored in the RAM 13 shown in FIG. Remembered.

Next, the operator searches for the OUT point OUT by the jog dial or the like as described above. In other words, in the still state, listen to the audio signal of the video, mix the noise,
Alternatively, the next point after the end point of the portion whose level should be changed is searched.

When the out point OUT is found,
The operator designates, for example, the OUT point OUT here. When the operator raises the fader (sets the position to raise the level), the time code obtained at this OUT point and this fader position data are stored in the RAM 13 shown in FIG.

In this way, the reason why the normal mode is used up to the IN point IN and after the OUT point OUT is that the time code data and fader data in the portion outside the editing section are stored in the RAM 13 and the data is stored. Because it will be destroyed.

Then, after the time code and fader position data are stored in the RAM 13 in this way, when the operator puts the VTR or the like into the reproduction state, the CP shown in FIG.
U10 generates the control signal as described above based on the time code from the VTR, the time code stored in the RAM 13, and the fader position data indicating the position of the fader moved at the time indicated by the time code.

For example, in the case of setting as shown in FIG. 7, the control signal is output from the CPU 10 at the position of the IN point IN, and this control signal is output via the output port 14 to the D port.
The motor 16 is supplied to the -A converter 15 and converted into an analog signal in the DA converter 15.
Is supplied to. Then, the motor 16 is driven to move the fader to the position indicated by the broken line in FIG. 7 (left side in the drawing), whereby the audio signal is output at a level corresponding to the position of the fader.

Subsequently, at the position of the OUT point OUT, the CPU 10
Control signal is output from the output port 1
Is supplied to the D-A converter 15 via the D.A.
It is supplied to the motor 16 after being converted into an analog signal in the A converter 15. When the motor 16 is driven, the fader moves to the position indicated by the broken line in FIG. 7 (on the right side in the drawing), whereby the audio signal is output at the level corresponding to the position of that fader.

As described above, in this example, the transport generator 6 (or CPU 10) compares the time codes to generate a flag indicating the reproduction mode of the video signal source,
Slow mode for storing time code and fader position data in RAM 13 based on the flag, or RAM
After setting the normal mode setting in which the time code and fader position data are not stored in 13 and setting the playback mode of the video signal source such as the VTR to the still or forward throw state, the normal mode and Since the slow mode is set between the point IN and the out point OUT and the normal mode is set after the out point OUT, it is possible to cope with a case where a short fader operation is required so that the operator cannot perform the fader operation. In the case of cutting noise and the like, only the noise can be cut, so that it is possible to obtain a very good sound without cutting all the sounds of one or several frames as in the conventional case.

The above embodiment is an example of the present invention.
It goes without saying that various other configurations can be adopted without departing from the scope of the present invention.
