Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window operation control system in which control of a target device can be operated on a monitor display of a computer, and more particularly, to a digital mixer in an audio system as a target device. The present invention relates to a system in which a control operation can be performed on a monitor / display of a computer.

[0002]

2. Description of the Related Art An audio system includes a mixer for adjusting the levels of signals from a plurality of sound sources, mixing the signals, and outputting the resulting signals. As one of the mixers having such a function, a digital mixer capable of digitally adjusting the level of a signal from each sound source is used. The digital mixer is computer-controllable, and controls the digital mixer by displaying controls corresponding to each of the sound sources in a window on a computer monitor display under the control of a computer program. An operator in the window is visually moved by an operation of a mouse or a keyboard by an operator, so that a corresponding signal level can be adjusted.

An operation device of the above-mentioned conventional digital mixer will be described with reference to FIG. In FIG. 3, reference numeral 1 denotes an arithmetic processing unit including a personal computer or the like. The arithmetic processing unit includes a ROM 11 and a RAM 12, and is connected to the monitor display 2 and the digital mixer 3. The ROM 11 stores a control program for controlling the mixing operation in the digital mixer 3, and under the control of the program, for example, three sound sources are displayed on the display 2 as shown in FIG. Source A
A window is displayed that shows the operators 21A to 21C provided corresponding to. Needless to say, the number of acoustic sources is not limited to three.

When such a window is displayed, the operator operates a mouse or a keyboard (not shown) to move the operator 21B corresponding to the sound source B within the operation range within the window of the display 2. When moved up and down, the data corresponding to the position of
It is stored in the address corresponding to the sound source B in M12. In this manner, the operators 21A to 21A
Every time the position of 1C is updated, the storage content of the corresponding address in the RAM 12 is updated.

[0005] Then, the arithmetic processing unit 1 executes the sound source A of the RAM 12 based on the control program in the ROM 11.
The data stored at the respective addresses provided corresponding to .about.C are transferred to the digital mixer 3.
The digital mixer 3 adjusts the signals from the audio sources A to C to provide a mixing output so as to have a signal level corresponding to the received data.

[0006]

In such a conventional apparatus, for example, as shown in FIG. 4 (b), two operations provided on the display 2 corresponding to the same sound source A are performed. It may be preferable to display the children 21A and 21A '.

[0007] That is, among the functions that can be provided by the digital mixer, the operation elements and other elements are adjusted according to the operation contents at the time of system adjustment and system operation, and the proficiency of a system administrator and a normal operator. There is a customization function for setting the display environment. With this function, for example, two operators (corresponding to the same sound source) customized according to the display environment are displayed in separate windows 1 and 2. In many window operation control systems, these windows are used. Is exclusively or alternatively displayed on the display. However, exclusively displaying the two operators corresponding to the same sound source imposes restrictions on the display to the operator.
As shown in (b), it is preferable that two operators are simultaneously displayed on the same screen.

As described above, when a plurality of operators are displayed on the same screen for one acoustic source, one of the operators is operated to update the storage data of the corresponding address in the RAM 12. Each time, the display position of the other operator must also be updated. This updating work is executed as follows by a program stored in the ROM 11 in the arithmetic processing device 1.

1. When it is detected that a certain operation element has been operated on the display, a redraw request is issued to all the operation elements. 2. When a redraw request is received, each operation element
The display position of the operation element is updated by performing the re-drawing with reference to the storage data at the address corresponding to.

As described above, since the redraw request is issued to all the operators, 100 operators are temporarily displayed on the screen, and two of them correspond to the same sound source. That is, if the same storage data value is displayed, a useless redraw request is made to 998 operators. In the above procedure 2, even if the position of the operation element is compared with the value of the stored data and optimization is performed so that the operation element is redrawn only when the value is different, in that case, the comparison is performed. Processing is required.

Therefore, when performing window operation control in a large-scale acoustic system or the like, the response speed for updating the display of the operating elements deteriorates as the number of operating elements to be displayed increases.

[0012] Further, even when a plurality of operators of the same set are displayed on a plurality of displays and a plurality of operators operate independently, the operators are moved on one display. Then, it is necessary to perform a redrawing process so as to match the position of the corresponding operation element on another display, and also in this case, the response speed for updating the display deteriorates.

As described above, in the conventional digital mixer operating device, when a plurality of controls corresponding to one sound source are displayed on one or a plurality of displays,
Each time the position of one of the controls is updated, it is necessary to redraw the other corresponding controls so that they are consistent with the updated position.
The process was extremely complicated and time-consuming.

[0014] Such a problem arises when the control target is a digital
This is a problem that occurs not only in the case of a mixer, but also in the control operation of another type of target device. An object of the present invention is to provide a window operation control system that can solve the problems in such a conventional window operation control system.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of a window operation control system according to the present invention will be described by taking as an example a case where window control is performed on a digital mixer for sound.

In the first embodiment, the hardware is the same as that shown in FIG. 3, but is characterized by software for controlling the window operation of the digital mixer. The mixing control software, as shown in FIG.
ONT-Obj, data object DATA-Ob
j and browser BRWS, which is display software
It consists of two software. These software are stored in the ROM 1 of the computer 1 shown in FIG.
1 or the RAM 12.

The control object is an operator 21A provided corresponding to each of the sound sources A to C.
To 21C, and a module including, as data, a meter 22 for displaying an input / output level of an acoustic signal,
These data are displayed on the display 2 under the control of the browser.
Displayed above. Then, when the operator operates, for example, the operator 21A on the display 2, the data A indicating the operation level in the object is updated by the method of the control object.

The data of the data object is associated with the data of the control object,
When the data A in the control object is updated, the data A of the data object associated therewith is updated. Then, the data object further updates the data of the corresponding address ADA in the RAM 12 by the method.

Similarly, the data B and C of the control object are associated with the data B and C of the data object, and when the operators 21B and 21C are operated, the control object and the data
The corresponding data B and C in the object are updated,
The data of the corresponding addresses ADB and ADC in the RAM 12 are updated.

In the mixing control software which is a feature of the present invention, each data of a data object can be associated with a plurality of data of a control object. Therefore, for example, in order to display the first operation element 21A and the second operation element 21A ′ corresponding to the sound source A on the display 2, the control object is composed of the two operation elements 21A and 21A.
When the data A and A 'of A' are included, these two data A and A 'are associated with one data A of the data object.

As described above, when the data of the control object and the data of the data object are associated with each other on a two-to-one basis, the data A of the data object is updated by updating the data A of the control object, for example. Then, the data object controls to update the data A ′ in the control object by the method. As a result, the two data A and A ′ in the control object have the same value.
A and 21A 'are both displayed at the same position.

Therefore, when one of the two operators 21A and 21A 'is operated on the display 2, the display position of the other is automatically corrected and the display positions of the two are matched. Since the redrawing process is not required, the response speed for updating the display is increased.

It will be apparent that a controlled device other than the digital mixer can be used as the target device. FIG. 2 shows a second embodiment of the window operation control system of the present invention. In this embodiment, the system has a network configuration. In FIG. 2, reference numeral 100 denotes a data object DATA-Obj.
, A control object CONT-Obj and a browser BR
A client 300 with a built-in WS is a target device (for example, a digital mixer) which is a device to be controlled. Reference numeral 400 denotes an intranet or the Internet. Although it is assumed in FIG. 2 that there are a plurality of clients, only one client may be used.

A plurality of clients are connected to the intranet 40
0, clients 200, 20
0 ', ..... each have the same control
An object and a browser are stored, and a window having one or a plurality of operators shown in FIG. 4A is displayed on a display. The operator is the target device 3
00 for controlling the number of control factors necessary for controlling the target device. The data for each control of the control object of each client is associated with the data of the data object of the server, and thus the client 2 corresponding to any control factor of the target device 300.
The operator of 00 is associated with the data of the corresponding operator of another client 200 ′,... Via the data object of the server 100.

In the system shown in FIG. 2, for example, in the client 200, when an operator operates an operator corresponding to a control factor on a window of the display, the corresponding data in the control object of the client is updated. Then, the control object of the client 200 transmits the new data updated via the intranet 400 to the server 100.
To the data object. In response, the data object updates the corresponding data in the object and rewrites the data at the corresponding address in the RAM in the server, ie, the address associated with the control factor, with new data. Thus, the target device 300 is controlled by the newly set control factor value.

The data objects of the server 100 also transfer the new data via the intranet 400 to the clients 200 ',... And correspond to the corresponding data in the control objects of these clients, ie the control factors. Update the data with new data. This updates the associated data in the control objects of all clients to the same value, so that the browser displays the corresponding controls on the displays of all clients at the same location.

As described above, in the system shown in FIG.
Since the control object and the data object can communicate via the intranet as a client and a server, even if the client is located at a remote location from the target device 300, the control factor of the target device can be set from the client. And remote control of the target device becomes possible.

When a plurality of clients are present, when a control on the display of one client is moved by the function of the data object of the server, the corresponding control in all the clients is moved. The display can be automatically changed so as to be at the same position as that of the operator, and alignment can be performed, and moreover, it can be performed in real time. Although any controlled device can be used as the target device 300, when an acoustic mixer is used as the target device, real-time response characteristics are required for displaying a window for controlling the mixer. Is very effective as an acoustic mixer control system.
