DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. The following embodiment is merely an example, and various modifications can be made without departing from the spirit of the present invention.

[System Configuration] FIG. 2 is a block diagram showing a schematic configuration of an audio system according to an embodiment in which the present invention is applied to an audio amplifier device. In this audio system 1, a digital or analog audio signal source such as a personal computer (PC) or a CD player, an MD (Mini Disk) player, a tape deck, and the like are connected to a plurality of external device connection terminals 21 to 24 provided on a rear panel. It can be connected and has a built-in tuner (not shown). Audio signals from these terminals 21 to 24 and the built-in tuner are input to the input selector 3.
And selectively connected to the audio amplifier 4. The audio signal from the audio source device selected by the input selector 3 is amplified by the audio amplifier 4 and emitted from the speaker via the speaker terminal 5. It should be noted that the numbers (enclosed numbers) “1” to “0” for representing the input selector position selected by the input selector 3 for convenience.
“5” corresponds to the external device connection terminals 21 to 24 and the built-in tuner.

In the audio system 1, the input selector 3 is controlled via a central processing unit (CPU) 7 in accordance with the operation state of the operation device 6.
A read-only memory (ROM) 9 and a random-access memory (RAM) 10 are provided. These elements 3, 6 to 10 are interconnected via a bus 11.

The operation device 6 has on the front panel any type of operation device such as a key switch (push button) and a dial (rotary selector) for setting / selecting various functions. It is provided on the operation panel. By operating the operation device of the operation device 6, it is possible to switch audio signals from the external device connected to the external device connection terminals 21 to 24 and the built-in tuner. The display device 8 is, for example, a fluorescent light (FL:
A multi-function display unit including a fluorescent luminescence display element and various indicators are provided, and these display units and indicators are provided on or adjacent to the operation panel.

The ROM 9 stores a predetermined control program and data for controlling the audio system 1. The data includes display data, and the control program includes a display program displayed on the display device 8. A display sequence that defines the display order of data and the like is included. For example,
The names of connected devices that are generally assumed are prepared in advance as ROM data, and as shown in FIG. 2, the assumed names correspond to the input selector positions “1”, “2”,. Can be registered in advance. An editable area is secured in the RAM 10 functioning as a work area, and the user can freely register a character string as illustrated in FIG. 2 in the editable area.

The audio system 1 is provided with a PC connection terminal 13 connected to the bus 11 via the interface 12. An external personal computer (PC) 14 can be connected to the PC connection terminal 13, and the ROM 9 is further provided so that the system main body 1 can be controlled from the external PC 14 when connected to the external PC 14. Program is stored.
The external PC 14 not only controls operations such as selector switching of the system body 1, but also controls the RAM 10
It is possible to execute processing such as registration of a character string in an editable area in the server and data rewriting. In addition, C of the system main body 1
The function of the PU 7 can be used to edit the display data stored in the RAM 10 and change the contents displayed on the display device 8 by operating the keys of the operation device 6. In the embodiment, the personal computer (P) connected to the system main unit 1 is used in view of the easiness and flexibility of editing operation and the variety of editing contents.
C) The display data such as the selector name data is changed by the operation 14.

[Outline of Operation] This audio system 1
With regard to the display of input devices and the like connected to the system, not only is the candidate data prepared in advance in the ROM 9 as described above, but also the user can edit using the external PC 14 and the edited The data can be stored in the RAM 10. With this configuration, when an input selection or the like is performed by operating the operating device 6 or the external PC 14, an input device or the like is selected by the input selector 3, and desired display data corresponding to the input device is set to RO.
It is selected from the M9 or the RAM 10 and displayed on the display device 8. Therefore, the name displayed corresponding to the function being selected can be arbitrarily changed to the specific content actually selected or the content according to the user's preference. A specific operation example is as follows.

(1) When “MD” is to be displayed when the input selector position “3” is selected As shown by the broken line in FIG. 2, an analog audio signal of the MD player 15 is connected to the external device connection terminal 23 as an external device. The user operates the operation device 6 with keys or the external PC 14 to connect the ROM 9 in advance.
The name "MD" corresponding to the external device 15 is selected from among the candidate names of the input selector position "3" prepared in the table, and the data "MD" is displayed when the input selector position "3" is selected. The audio system 1 is set so that it is preferentially displayed on the multi-function display unit of the device 8. By setting in this way, when the input selector position “3” is subsequently selected, the input selector name “MD” is preferentially displayed on the multi-function display section of the display device 8.

(2) When "TAPE" is to be displayed when the input selector position "4" is selected As shown by the broken line in FIG. 2, the tape deck 16 is connected to the external device connection terminal 24 as an external device. The user inputs a character string corresponding to the name of the external device 16 from the external PC 14 connected to the PC connection terminal 13. This allows the audio system 1 to perform, for example, “TAP
The character data "E" is received and stored in the editable area in the RAM 10, and the setting is made so that the data "TAPE" is displayed preferentially when the input selector position 4 is selected. By doing so,
When the input selector position “4” is selected, an input selector name “TAPE” is preferentially displayed on the multifunction display section of the display device 8.

The space between the external PC 14 and the audio system main unit 1 is also indicated by a two-way arrow in FIG.
Bidirectional data transfer is possible. In one embodiment of the present invention, as described later (see FIG. 4), the external PC 14
A USB (Universal Serial Bus) cable is used for connection with the device. Originally, if the purpose is merely to change or correct the display characters to be displayed on the audio system 1, one-way data transfer from the external PC 14 to the audio system 1 may be used. However, external PC1
4 requests the audio system 1 for character string information and the like by the display character string editing program executed on the
In some cases, it is necessary to perform data transfer processing to the C14, so a data transfer system (cable and interface) that can transfer data bidirectionally using a USB or the like is required.

For example, suppose that some trouble occurs in the external PC 14 and it is necessary to reinstall application software as a character string editing program in the external PC 14. In this case, when the software is reinstalled, the installation program reads character string edited data stored in the audio system main body 1, for example, selector name data, and transfers the read selector name data to the USB. The data is transferred and stored in the external PC 14 via the cable. Thus, once the application software is installed on the external PC 14 and the character string is edited together with the audio system, the system main unit 1
Since the character string data is stored on the side, even when the character string editing data on the external PC 14 is lost and the application software needs to be reinstalled, the selector name data is stored using the keyboard of the external PC 14 or the like. This eliminates the need for the operation of inputting again.

Conversely, for example, it is assumed that the power supply of the audio system main unit 1 has not been supplied for several weeks and the backup memory in the system main unit 1 has been cleared (the data has been unexpectedly erased). In such a case, if the application software is started on the external PC 14, the selector name data stored on the external PC 14 can be saved in the main body memory at the time when the software is started.

[Front Panel and Rear Panel] FIGS. 3 and 4 show examples of the configuration of the front panel and the rear panel of the audio system 1 according to one embodiment of the present invention. In this example, the operation unit of the operation device 6 provided on the front panel (FIG. 3) includes a plurality of push-button input selection switches 6a1 to 6a4 and a DSP switch 6.

FIG. 5 shows an external PC in the audio system according to one embodiment of the present invention.
In this example, the user operates the external PC 14 to register a desired input selector name in an editable area in the RAM 10 of the audio system 1 by this process. it can. When the power is turned on, an application program including this processing flow is started in step P1. In step P2, "edit selector name", "edit DSP mode name", and "edit page name" are displayed on the display of the PC 14.
Main menu screen (not shown) including edit items such as
Is displayed.

In step P3, when the user selects the edit item "selector name" from the main menu, the mode is changed to the selector name edit mode, and the selector 14 is displayed on the display of the PC 14 as shown in FIG. The name edit mode screen is displayed. In Step P4, the user operates the external device input terminals 21 of the audio system 1

It should be noted that the case where an edit item such as "edit DSP mode name" or "edit page name" is selected from the main menu displayed on the PC display in step P2 is not shown, but the same is true. After editing, character string data representing a desired DSP mode name or page name can be transferred from the external PC 14 to the audio system 1.

FIG. 7 shows an example of a processing flow executed by the system main body in the audio system according to one embodiment of the present invention. By this processing, the user operates the system main body 1. By performing key input by operating each of the input selection switches 6a on the slave device 6, a desired input selector name can be displayed on the multi-function display section 8d of the display means. When the power is turned on by pressing the power-on / standby switch 6g, the power indicator 8p is turned on, and this processing flow is started at a predetermined clock time interval. 6a-6e
It is determined whether or not there is a key input by such an operation.

If it is determined in step S1 that there is no key input, the flow advances to step S2 to determine whether or not a command has been received from the external PC 14. If a command has been received, the flow further advances to step S3. It is determined whether the received command is a selector name rewriting command. If it is determined in step S3 that the received command is a selector name rewriting command, the selector name display data transferred with this command is stored in the RAM 10
Is stored in the editing area corresponding to the input selector position number, and if data is already stored in the position corresponding to the input selector position number, this is updated. By the processing in step S3, for example, the above-described character string “DVD” corresponding to the input selector position numbers “1” to “4”
−α ”,“ PC-AN1 ”,“ MD-1 ”,“ TAP
E "can be stored as display data.

On the other hand, if it is determined in step S1 that a key input has been made, the flow advances to step S5 to execute an operator response process according to the content of the key input, and then returns to step S1. In step S5, for example, when the “PC” input selection switch 6a1 of the input selection switches 6a is operated, the “PC-D” connection terminal corresponding to the input selector position number “1” for each pressing operation PC via 21
Connected sequentially to a state where digital audio signals are received from the built-in DVD player, and a state where analog audio signals are received from the PC built-in sound card via the "PC-A" connection terminal 22 corresponding to the input selector position number "2" Perform switching.

When the "AUX1" input selection switch 6a2 corresponding to the input selector position number "3" is operated, a digital audio signal source such as a CD player is connected to the "AUX-D" connection terminal 231. Receives the digital signal with priority, and when a digital audio signal source is not connected to the connection terminal 231, an analog audio signal such as a CD player, MD player or tape deck connected to the “AUX-1” connection terminal 232. The connection is switched so as to receive the analog audio signal from the signal source. When the “AUX2” input selection switch corresponding to the input selector position number “4” is operated, an analog audio signal input from a CD player, an MD player, a tape deck or the like via the “AUX-2” connection terminal 24 Is selected and the "TUNER" input selection switch corresponding to the input selector position number "5" is operated, and every time the operation is pressed, the FM / AM switching of the FM / AM tuner built in the system main body 1 is performed. And FM forced monaural switching.

Therefore, as in the case of the above (1),
The MD player 15 is connected only to the “AUX-1” connection terminal 232 corresponding to the input selector position “3”,
When the “AUX1” input selection switch is operated, the ROM 9
The selector name “MD” is set so as to be preferentially displayed from among the candidate names of the input selector position “3” in the. When the “AUX1” input selection switch is operated thereafter, the display device 8 On the multi-function display section, the input selector name “MD” is displayed with priority.

In step S3, as described above,
The PC corresponding to the input selector position numbers "1" to "4"
The built-in DVD player, PC built-in sound card, MD player 15 and tape deck 16 are connected to terminals 21, 22,
231 and 24, and the character string data “DVD-
α ”,“ PC-AN1 ”,“ MD-1 ”,“ TAPE ”
Is stored as selector name display data, and these data are set so as to be preferentially displayed. Thereafter, the multi-function display section 8d of the display device 8 is provided with an input for each operation of the "PC" input selection switch. Selector name "DVD-
α ”and“ PC-AN1 ”are sequentially displayed with priority, and“ A ”
When the “UX1” or “AUX2” input selection switch is operated, the input selector names “MD-1”, “TAP”
E "is displayed preferentially.

When the DSP switch 6b is turned on, every time the up / down switches 6d and 6e are operated,
The DSP program name is sequentially displayed on the multi-function display section 8d, and the DSP program is determined by operating the DSP switch 6b again. further,
FM / A by "TUNER" input selection switch 6a4
When the tuner setting switch 6c is operated when the M tuner is selected, the switching of the preset memory page and the switching of the manual channel selection operation are performed every time the switch 6c is pressed, and the up / down operation is performed. When the switches 6d and 6e are operated, selection of a preset memory number (page) or up / down of the reception frequency (tuner operation) is performed according to the operation state of the tuner setting switch 6c.

If it is determined in step S3 that the received command is not a selector name rewriting command, another process corresponding to the received command is executed in step S6, and the process returns to step S1. Such other processes include, for example, an operator response command in place of the operation of the operator operation 6, and a name rewriting command such as a DSP mode name rewriting command and a page name rewriting command. In the case of an operator response command, an operator response process similar to the process exemplified in step S5 is performed by a key operation of the external PC 14 or the like, and in the case of a name rewriting command, step S4

“JAZZ”, “GHURCH”, “ENTERI
MENT "," MOVIE THEATER "," CO
The mode name display data corresponding to each mode is stored in the RO so that “NCERT VIDEO” or the like is displayed on the display device 8.
It is prepared in advance in M9. At the same time, when the editing item of “DSP mode name editing” is selected from the main menu displayed on the PC display in step P2 using the PC 14 as described above, each mode name is matched to the user's preference. Edit to an arbitrary name such as "Budokan", "Madison Square",...
Set within 10. Thus, when a mode is selected by operating the mode setting key, the mode name freely customized by the user can be preferentially displayed on the multi-function display section 8d of the display device 8.

[Tuner page name editing] For the display of the tuner page name, a page switching key (6a4,
6d, 6e), for example, the page name “Pa
The page name display data is prepared in advance in the ROM 9 so that “ge A”, “Page B”,... are displayed on the display device 8. At the same time, the PC 14 is used to execute the processing in step P2 as described above. When an edit item of “page name edit” is selected from the main menu displayed on the PC display, each page name is changed to “rock”, “jazz”, “j-pop”,.
And so on, and set this in the RAM 10 of the audio system main body 1 as page name display data. Thus, when a page is selected by operating the page switching key, the page name freely set by the user can be arbitrarily displayed on the multifunction display section 8d of the display device 8.

[Effects of the Invention] As described above, according to the present invention, the display data corresponding to the function provided in the system is edited by the editing means, and the display data is stored in the storage means. Since a storage unit in which data is pre-recorded is further provided, the data displayed on the display unit can be freely changed by the user to a name corresponding to the actual function or a favorite name. As the data, a name prepared in advance can be used as it is, and furthermore, display data recorded or stored in both storage means can be automatically displayed according to a function selection operation.

Also, the present invention provides an input selector, a DSP
It can be applied to the mode, tuner page setting, etc., and the input selector name can be freely changed to the name of the device actually connected or the user's favorite, and it is possible to determine which terminal is connected to what. , The user can customize the name of each DSP mode and customize the name of each page of the tuner program memory according to the contents. For example, a display according to a specific function actually selected or set or a display according to the user's preference can be obtained.

Further, in the present invention, the display data is edited by GUI operation using a general-purpose personal computer, whereby the display name on the GUI is edited and reflected on the display of each function in the system main body. The display data editing operation can be made extremely simple.
