[Field of the Invention]
The present invention relates to a signal processing apparatus capable of signal input / output processing and a control program for the apparatus.
[0002]
[Prior art]
Conventionally, a signal processing device such as a mixer device capable of signal input / output processing such as mixing processing, for example, selectively inputs audio signals from a plurality of signal systems, and adds processing processing such as various effects to it, Output to a desired system. This apparatus also includes a user define key and a general purpose interface (GPI), and various functions can be assigned to these keys. For example, in GPI, effects can be turned on / off, scene recall, “recording” lamp control outside the studio, console solo function can be triggered, effect library recall function can be assigned, etc. it can. As GPI, a plurality of (for example, eight) interlocking processes can be assigned.
[0003]
More specifically, the mixer apparatus is connected with a signal processing unit that is an engine for performing mixing processing. A plurality of signal processing units are provided as spares (with mirrors), and the first signal processing unit is down. In some cases, the uninterruptible power supply works, and it is usually performed to switch to the spare second signal processing unit and continue the processing. In this case, the GPI is set so that the function process of switching the signal processing unit is automatically executed in conjunction with receiving the signal indicating that the uninterruptible power supply has been activated.
[0004]
Alternatively, when the lamp indicating that the voice monitor is being executed is small and difficult to see, a GPI is set so that a separately provided large lamp emits light in conjunction with the execution of the voice monitor. Can be recognized. In addition, it is possible by GPI to make a specific operation unit have a desired function or a plurality of functions by associating a specific operation unit such as a fader with a desired operation such as sound reproduction of a recorder.
[0005]
In addition, the GPI can be used as an additional key for a user-defined key, a shortcut key, a remote control switch, a remote switch, an interlocking switch between devices, and the like, and its usage is infinite due to the user's ingenuity.
[0006]
As described above, in GPI, a function to be executed in response to a specific input signal such as a signal based on an operation of an operator or a tally signal from an external device (such as a large lamp) is set in advance and When the input signal is received, the corresponding function can be executed by using it as a trigger.
[0007]
[Problems to be solved by the invention]
In general, with respect to a signal processing apparatus, wiring and equipment settings are often complicated, and a desired operation cannot be performed unless both are set correctly. In order to find out the cause after a problem actually occurs, it takes a lot of time and effort to continuously check the setting state of wiring and devices one by one or to perform setting again. Therefore, in order to confirm whether or not the GPI setting state is appropriate, it is desirable to perform a test to confirm whether or not the function processing is executed as expected, sufficiently before the actual production. However, there are cases where it is difficult to perform the same functional processing as the test as a test.
[0008]
For example, if the function of switching the signal processing unit when the uninterruptible power supply is activated is actually tested in the same manner as in actual production, an excessive burden may be imposed on the device, so that a preliminary test is difficult.
[0009]
Also, when a scene is created using a dedicated application on a personal computer connected to the signal processing device, the signal processing unit and other peripheral devices, which are mixer functions, are the same as in production. If it is not actually connected, the operation cannot be confirmed.
[0010]
The present invention has been made to solve the above-described problems of the prior art, and an object of the present invention is to perform an operation of a function to be executed in response to an event without causing a specific event in the mixing process. It is an object of the present invention to provide a signal processing apparatus capable of performing confirmation and a control program for the apparatus.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the signal processing apparatus according to claim 1 of the present invention is capable of performing a mixing process for selectively inputting signals from a plurality of signal systems and outputting the input signals to a desired signal system. In the signal processing apparatus, function association means for individually associating each of the plurality of input signals with each of the plurality of functions , and test execution for individually setting whether to test the plurality of functions for each function and setting means, if the input signal is input, corresponding to the function in which the function executing unit to execute the function corresponding to the input signal which is the input, is possible to perform the test by the test execution setting unit is set and a virtual input state creation means to create a state where the input signal is input to the virtual, the function execution unit, by the virtual input condition creation unit, configured to perform the test is not set If the condition where the input signal corresponding to the function is entered is created virtually, by executing the function corresponding to the input signal, and performs an operation check of the function.
[0012]
According to this configuration, in the mixing process, even if a phenomenon that an input signal is actually input does not occur, a function that should be executed in conjunction with an input state as a virtually input state A similar function can be performed as a test. Therefore, in the mixing process, even if a specific event does not actually occur, it is possible to confirm the operation of the function to be executed in response to the event.
[0013]
To achieve the above object, a control program for a signal processing apparatus according to claim 4 of the present invention is a mixing process for selectively inputting signals from a plurality of signal systems and outputting the input signals to a desired signal system. Is a control program for a signal processing apparatus capable of individually associating each of a plurality of input signals with each of a plurality of functions , and whether to test the plurality of functions. a test execution setting step of setting individually for each, if the input signal is input, a function execution step of executing a function corresponding to the input signal which is the input, is possible to perform the test by the test execution setting step program for executing a virtual input state creation step of creating a state where the input signal corresponding to the set functionality is input virtually the computer There, the function execution step, said the virtual input state creation step, when a state where the input signal is input corresponding to the function to perform the test is set is created virtually, the input The operation of the function is confirmed by executing the function corresponding to the signal.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0016]
FIG. 1 is a block diagram showing the overall configuration of a signal processing apparatus according to an embodiment of the present invention. This apparatus is configured as, for example, a mixer apparatus.
[0017]
This apparatus includes a display 2, a fader 3, an operator 4, a flash memory 5, a RAM 6, a PCI / O (personal computer input / output unit) 7, a GPII / O (general purpose interface input / output unit) 8, and a signal processing unit ( DSP) 21 is connected to the CPU 1 via the bus 9. The PCI / O connects a PC (personal computer) 27.
[0018]
The display 2 is composed of an LCD or the like, and displays various information such as a setting screen. The flash memory 5 stores various data and also stores an operation program executed by the CPU 1. The fader 3 adjusts the volume and the like for each channel. The operation element 4 is used for inputting various information. The RAM 6 temporarily stores various data.
[0019]
The CPU 1 controls the entire apparatus such as the signal processing unit 21 and the display 2. The CPU 1 detects the position of the fader 3 and the operation of the operation element 4. The fader 3 is provided with a drive unit (not shown) such as a motor, and the fader 3 can be driven to a designated position in accordance with a control signal from the CPU 1 (moving fader).
[0020]
The signal processing unit 21 performs mixing processing such as input of signals from a plurality of systems, application of effects, and output of signals to an arbitrary system. AD / DIO (analog-digital conversion BOX / digital interface BOX) 23 (1) to 23 (10) is connected to the signal processing unit 21 via connectors 22 (1) to 22 (10). ing. Each analog-digital conversion BOX of the AD / DIO 23 can have up to eight A / D conversion boards, and the gain and polarity can be set for each input. Each digital interface BOX can have up to eight I / O boards.
[0021]
The signal processing unit 21 is also connected with DA / DIO (digital-analog conversion BOX / digital interface BOX) 26 (1) -26 (6) via connectors 24 (1) -24 (6) for output. Has been. The gain and polarity can be set for each digital-analog conversion BOX output of the DA / DIO 26. Each digital-analog conversion BOX can be extended with up to eight D / A boards.
[0022]
The flash memory 5 stores a patch library (PATCH), a name library (NAME), and a unit library (UNIT). Detailed description thereof will be omitted. The flash memory 5 also stores about 1000 scenes (SCENE). The scene includes settings for each input channel (effects, faders, output destination, output level, etc. for each channel), settings for each output channel (effects, faders, input source for matrix output channels, input levels, etc.), Includes built-in effector settings, built-in equalizer settings, and monitor settings. The scene also includes a setting for a patch (wiring recombination) that defines which input port (physical channel) the input channel receives and outputs to which output port. Each scene is given a serial number, and can be recalled in order as will be described later.
[0023]
In addition, this apparatus is provided with a spare signal processing unit (not shown) configured in the same manner as the signal processing unit 21. When the signal processing unit 21 that normally operates goes down, an uninterruptible power supply is provided. At the same time, it is switched to a spare signal processing unit so that the continuation of processing is maintained. Connected to the GPII / O8 are a switch 10, an LED 11, and recorders 12 and 13, which are external devices provided separately from the present apparatus. The recorders 12 and 13 are also connected to AD / DIOs 23 (1) and 23 (2).
[0024]
In GPII / O8, a signal based on the operation of the fader 3 or the operation element 4, a “tally signal” indicating the state of the recorders 12 and 13 (for example, a play tally signal indicating a playback state), and the signal processing unit 21 are down Various signals such as an “uninterruptible power supply operation signal” indicating that the uninterruptible power supply has been activated are input. As will be described later, functions to be executed in response to these various input signals can be preset in the GPI, and when a specific input signal is received, the function corresponding to that is executed as a trigger. Can be done.
[0025]
FIG. 2 is a diagram illustrating an example of the GPI setting screen. The GPI setting screen 31 includes a GPIIN setting 32, a GPIOUT setting 33, and a test button 34.
[0026]
In the GPIIN setting 32, ON / OFF of the test, polarity, function, and parameter are set for each GPI port, that is, the input unit. In the GPIOUT setting 33, in correspondence with the GPIIN setting 32, the link state, activation designation source, parameter, polarity, and test ON / OFF are set for each output unit. It should be noted that the setting state of each item of the GPIIN setting 32 and the GPIOUT setting 33 is indicated by being highlighted.
[0027]
Here, the “function” of the GPIIN setting 32 defines the content of processing executed according to the “parameter” when a predetermined input signal is input. “Parameter” defines a corresponding output unit and detailed contents (mode, etc.). For example, in the GPIIN setting 32, “GPI TRANSPORT” is set as the “function” in the input unit 1, and “GPIOUT2, MODE = PLAY” is set as the “parameter”. Correspondingly, in the output unit 2 of the GPIOUT setting 33, “GPIIN1” having a correspondence relationship is set in the “activation designation source”, and “TRANSPORT = PLAY” is set in the “parameter”.
[0028]
Note that the function “TRANSPORT” is to execute a process of issuing a predetermined operation instruction to another device directly connected to the GPII / O 8 without going through the bus 9 in accordance with an input signal. is there. For example, in “TRANSPORT” illustrated in the figure, when a predetermined input signal (for example, an operation signal of the switch 10) is input to the input unit 1 from a corresponding element, the recorder 12 is played back as a trigger. The
[0029]
More specifically, for example, when the switch 10 is pressed, the signal is input to the input port of the input unit 1 (GPIIN1) set to GPII / O8, and is received and set to the GPIIN1. A GPI-TRANSPORT signal is output to GPIOUT2 of the function being performed. Assuming that the recorder 12 is connected to the GPIOUT2, the recorder 12 receives the GPI-TRANSPORT signal and controls its drive. Then, the recorder 12 outputs the reproduced audio signal to a port in the AD / DIO 23 (1).
[0030]
In addition to this, when the recorder 12 is played back, a tally signal is set to be output, the tally signal is set to be input to a GPIIN other than the GPIIN1, and the function setting in the GPIIN is further set. The LED 11 may be connected to the GPIOUT (different from the GPIOUT2) to enable lighting control. In this case, when the switch 10 is pressed, reproduction by the recorder 12 is started and the tally signal is input. Then, the user can recognize that the reproduction has started by the lighting state of the LED 11. Depending on the setting of the tally signal, the check is not limited to the start of reproduction but can be performed in stages.
[0031]
FIG. 3 is a diagram illustrating an example of a function and parameter setting screen for each input unit of the GPIIN setting 32. The function and parameter setting screen 35 is displayed by instructing any input part of the GPIIN setting 32 of FIG.
[0032]
In the function setting 36 on the function and parameter setting screen 35, in addition to the “GPI transport” corresponding to “TRANSPORT”, “scene memory recall”, “page selection”, “user defined LED”, and the like can be set. In addition, various functions can be set. In the parameter setting 37, a parameter is set for each function setting. For example, the recall type “INC” is set as a parameter for the function setting “scene memory recall”. In this case, the number is incremented every time there is an input signal, and the next scene is called. In this case, the input signal may be input when the switch 10 is turned on, for example, by setting the input unit of the GPIIN setting 32. Thereby, a desired scene can be easily called by a switch operation.
[0033]
In addition, as an example of GPI setting, for “page selection”, the next page, the previous page, etc. can be set as parameters, and when it is set to the next page, the screen display is the next each time there is an input signal. Switch to the page.
[0034]
For the “user-defined LED”, for example, although not shown, a “CUE” switch for voice monitoring and a small LED are provided along with the fader 3, and when the “CUE” switch is turned on, a small LED is displayed. It emits light to inform you that it is being monitored. In this case, when an ON signal of the “CUE” switch is input, the LED 11 (assuming that it is larger than the small LED) may be caused to emit light. Thereby, the monitor state is confirmed more clearly. In particular, by causing the LED 11 to emit light in conjunction with a dangerous change, a serious situation can be avoided.
[0035]
In addition, as described above, when a signal indicating that the uninterruptible power supply has been operated is input, the signal may be switched to a spare signal processing unit. Further, when the play tally signal from the recorder 12 is input, the LED 11 may be caused to emit light to recognize that it is in a playback state. Alternatively, the playback of the recorder 13 may be started when the level of the fader 3 becomes equal to or higher than a predetermined level. The number of combinations of input signals and functions to be executed is four in the example of FIG. 2, but is not limited to this, and a larger number of combinations may be configured.
[0036]
As shown in FIG. 2, in the GPIIN setting 32 and the GPIOUT setting 33, “polarity” can set whether the signal input / output corresponds to a change from low to high or high to low. The “polarity” can be set to either toggle (maintain change) or trigger (eg, 300 msec pulse). The “test” of the GPIIN setting 32 and the GPIOUT setting 33 is set to “ON” by turning on the corresponding test buttons 34 (1) to 34 (4), and the test is executed.
[0037]
The test execution virtually creates a state in which an input signal is input from an element (for example, the operation element 4, the switch 10, the recorder 12, or the like) corresponding to the input unit in which the item “test” is set to “ON”. That is done. For example, when the input signal is a + 5V pulse signal, the same + 5V signal is input to the input unit. In this case, the subsequent processing is exactly the same as when an input signal is actually input from the element, and a control signal is output to the element (for example, the display 2, LED 11) corresponding to the output unit. It should be noted that the control signal to be output to the element corresponding to the output unit when it is input to the input unit without the input signal being input to the input unit is output when the test button 34 is turned on. It may be.
[0038]
FIG. 4 is a flowchart of the GPI setting process. First, it is determined whether or not a GPI setting instruction has been issued (step S401), and the determination is repeated until a setting instruction is received. If there is a setting instruction, the GPI setting screen 31 shown in FIG. It is displayed (step S402). Next, on the GPI setting screen 31, selection of a GPI port, that is, an input unit is accepted (step S403), and the “function and parameter setting screen 35” (FIG. 3) which is the current setting of the selected GPI port is displayed. The screen is displayed on the device 2 (step S404). Next, the setting is accepted on the function and parameter setting screen 35 (step S405), the data is rewritten with the accepted setting (step S406), and this processing is terminated.
[0039]
The GPI can be set in advance (preparation) with the PC 27, and the created setting data can be transmitted to the signal processing apparatus.
[0040]
FIG. 5 is a flowchart of the GPI test process. First, in the GPI setting screen 31, it is determined whether or not the GPI test instruction is turned on (any one of the test buttons 34 (1) to 34 (4) is turned on) (step S501). If there is no input, the process proceeds to step S504. On the other hand, if a test instruction ON is input, a phenomenon corresponding to the ON test button 34 is created (step S502). That is, a state in which a predetermined input signal is input from an element corresponding to the input part of the GPIIN setting 32 defined by the test button 34 is virtually created. In the present embodiment, the same input signal as that when the phenomenon occurs is input to the input unit. Next, the display 2 displays that it is in the test state (not shown) (step S503), and proceeds to step S504.
[0041]
In step S504, it is determined whether or not a GPI test instruction OFF is input. The test instruction OFF can be input by, for example, pressing the test button 34 that is ON again. If it is determined that the GPI test instruction is turned off, the created phenomenon is stopped (step S505), and the display of the test state on the display 2 is stopped (erased) (step S506). ), This process is terminated. On the other hand, if there is no GPI test instruction OFF input, this process ends without stopping the above phenomenon.
[0042]
FIG. 6 is a flowchart of the interrupt process. First, the input of each operator (operator 4 and fader 3) is scanned (step S601), the presence / absence of a control signal from the outside is scanned (step S602), and other signal changes (for example, through GPII / O8). Reception of a tally signal, etc.) is detected (step S603), and this process is terminated. Note that in the scanning and detection in steps S601 to S603, an input signal that is input by being virtually created is also a target.
[0043]
FIG. 7 is a flowchart of GPI execution processing. First, whether the signal scanned and detected in the interrupt processing of FIG. 6 is set by GPI, that is, a predetermined input signal from an element corresponding to any input part of GPIIN setting 32. Whether or not (step S701). If it is determined that the input signal is a predetermined input signal (ON signal) from an element (for example, the switch 10) corresponding to one of the input units, the function process is executed according to the setting (step S702). That is, according to the setting of “function” and “parameter” of the GPIIN setting 32, a function corresponding to the input signal is transmitted by sending a control signal to an element (for example, the recorder 12) corresponding to the output unit of the GPIOUT setting 33 (for example, For example, playback of the recorder 12) is executed. Thereafter, this process is terminated.
[0044]
Here, even if the scanned and detected signal is input by being virtually created, it is similarly determined as “YES” in step S701. In step S702, the corresponding functional process is executed as in the case where the phenomenon actually occurs. This allows testing.
[0045]
According to the present embodiment, by providing a test function, even if a phenomenon in which an input signal is actually input does not occur, the signal should be virtually executed in conjunction with the input signal. A function similar to the function can be executed as a test. Therefore, even if a specific event does not actually occur, it is possible to confirm the operation of the function to be executed in response to the event. In addition, the test can be individually executed for each combination of the input unit of the GPIIN setting 32 and the output unit of the GPIOUT setting 33, which is convenient. Furthermore, since the test button 34 is provided on the GPI setting screen 31, the test execution operation is easy.
[0046]
Further, by applying a test function, a certain function process can be executed only by an operation on the GPI setting screen 31, and the test button 34 can be used as an execution switch.
[0047]
In the GPI setting screen 31, the elements corresponding to the input unit and the elements corresponding to the output unit may be built-in components such as the display 2 and the operation element 4, the switch 10, the recorder 12, and the like. May be an external device.
[0048]
It should be noted that the same effect may be obtained by reading a storage medium (not shown) storing a control program represented by software for achieving the present invention into the apparatus, and in that case, reading from the storage medium is possible. The issued program code itself realizes the new function of the present invention, and the storage medium storing the program code constitutes the present invention. Further, the program code may be supplied via a transmission medium (not shown), and in that case, the program code itself constitutes the present invention. As a storage medium in these cases, a floppy (registered trademark) disk, a hard disk, an optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, and the like can be used in addition to the ROM.
[0049]
【The invention's effect】
As described above, according to the present invention, it is possible to confirm the operation of a function to be executed in response to an event without actually causing a specific event in the mixing process .
