Description

  The present invention relates to an input setting device, and more particularly, to an input setting device that allows an operator to assign and set an input terminal to a selector without requiring a complicated operation.

  An AV amplifier used in an AV (audio visual) system includes a plurality of input terminals, and a plurality of playback devices (DVD player, VTR, set top box, etc.) are connected. The device to be played can be selected. In such an AV amplifier, an input terminal can be assigned to the selector. In this case, the input terminal selected by the selector can be freely changed. For example, even if the DVD player is connected to any input terminal, if the DVD selector is selected, the input terminal to which the DVD player is connected is selected. can do. Examples of the selector include a DVD selector and a video 1 selector to a video 4 selector. Examples of the video input terminal include a component terminal, a D4 terminal, an HDMI terminal, a composite terminal, and an S video terminal. The component terminal, the D4 terminal, and the HDMI terminal do not have as many terminals as the number of selectors, and these terminals are generally assigned to arbitrary selectors by a user operation. On the other hand, a composite terminal and an S video terminal are provided for each selector, and an input terminal is assigned in advance to the selector, and the assignment cannot be changed by a user operation.

  The assignment setting of the input terminal to the selector is performed according to the OSD (on-screen display), but an extremely complicated operation is required. As an example, a case where a component 1 terminal, a component 2 terminal, a component 3 terminal, an HDMI 1 terminal, an HDMI 2 terminal, a composite terminal, and an S video terminal are provided will be described.

  To assign a component terminal to the selector, the component assignment table shown in FIG. In the component assignment table, “IN1”, “IN2”, “IN3”, “NO” can be set in association with each selector, and the component 1 terminal is assigned to the selector in which “IN1” is selected. The component 2 terminal is assigned to the selector with “IN2” selected, the component 3 terminal is assigned to the selector with “IN3” selected, and the component terminal is assigned to the selector with “NO” selected. I can't.

  In order to assign the HDMI terminal to the selector, the HDMI assignment table shown in FIG. 4 is OSD-displayed. In the HDMI assignment table, “IN1”, “IN2”, and “NO” can be set in association with each selector, and the HDMI1 terminal is assigned to the selector for which “IN1” is selected, and “IN2”. The HDMI2 terminal is assigned to the selector for which “NO” is selected, and the HDMI terminal is not assigned to the selector for which “NO” is selected.

  Even when the D4 terminal exists, when the D4 terminal is allocated to the selector, it is necessary to set the D4 allocation table shown in FIG. 3 as described above.

  When the selector selects the composite terminal or the S video terminal, the composite terminal and the S video terminal are provided for each selector and cannot be assigned to any selector by a user operation. Therefore, an allocation table as shown in FIGS. 2 to 4 is not provided. In this case, by setting all the corresponding selectors in the allocation tables shown in FIGS. 2 to 4 to “NO”, the selector can select composite or S-video. The selector automatically selects one of the S video terminal and the composite terminal to which the cable is connected, but when both are connected, the S video terminal is preferentially selected.

  The above allocation operation has the following problems. When assigning a component terminal, D4 terminal or HDMI terminal to a selector, it is necessary to display each allocation table on the monitor OSD and assign an input terminal to the selector, while selecting a composite terminal or S-video terminal as the selector In this case, the allocation table does not exist at these terminals, and it is necessary to set all the corresponding selectors of the component, D4, and HDMI allocation tables to “NO”. This operation is very difficult for the user to understand and is complicated. . For example, when changing the allocation of the DVD selector from the HDMI 1 terminal to the component 1 terminal, first the DVD selector in the HDMI allocation table is changed from “IN1” to “NO”, and then the DVD selector in the component allocation table is set to “NO”. It is necessary to change from “IN1” to “IN1”, which is very troublesome. In other words, if the DVD selector in the HDMI allocation table remains “IN1”, the DVD selector in the component allocation table cannot be changed from “NO” to “IN1”, which causes confusion for the user. These problems are caused by the OSD display of the assignment tables as shown in FIGS. 2 to 4 for each type of input terminal.

JP 2003-109363 A

  The present invention has been made to solve the above-described conventional problems, and an object thereof is to provide an input setting device that allows a user to easily assign an input terminal to a selector without requiring a complicated operation. It is in.

  An input setting device according to a preferred embodiment of the present invention is provided with one or a plurality of input terminals to which a video signal or an audio signal is input, an assignment to a selector is predetermined, and the assignment cannot be changed according to a user operation, and a user operation The input terminal group including one or a plurality of input terminals that can be assigned to the selector and a plurality of the selectors, and one selector is selected from the plurality of selectors. Selection means for selecting an assigned input terminal, assignment means for assigning the input terminal to the selector according to a user operation, and an input for which assignment to the selector is determined in advance. An assignment setting screen for selecting one input terminal in accordance with a user operation from the terminals and input terminals that can be assigned to the selector in accordance with a user operation is displayed on the selection screen. And a assignment setting screen displaying means for displaying each data. The assigning means assigns the selected input terminal to the selector when the input terminal selected on the assignment setting screen is an input terminal that can be assigned to the selector according to a user operation. When the selected input terminal is an input terminal that is assigned to the selector in advance, the input terminal that can be assigned to the selector is assigned to the selector so that the selector selects the input terminal. Release all of.

  An assignment setting screen for setting an input terminal to be selected by the selector (assignment state) is displayed for each selector. On the assignment setting screen, the user selects an input terminal to be selected by the selector from among an input terminal that is assigned in advance to the selector and an input terminal that can be assigned to the selector according to a user operation. Therefore, when the user causes the selector to select any input terminal, it is only necessary to perform a setting operation on the assignment setting screen, which makes the operation very easy. In the assignment setting screen, when an input terminal that can be assigned to a selector is selected in response to a user operation, the input terminal is assigned to the selector, while an input terminal that is assigned in advance to the selector is selected. This is because the assignment of the input terminal that can be assigned to the selector according to the user operation is automatically released to the selector. Therefore, for example, when changing the allocation of the DVD selector from the HDMI 1 terminal to the component 1 terminal, the user only has to change from the HDMI 1 terminal to the component 1 terminal on the allocation setting screen.

  In a preferred embodiment, the allocation setting screen display means includes a connection area for selecting a type of an input terminal to be selected by the selector, and an input for selecting an input terminal according to the type of the input terminal selected in the connection area. The allocation setting screen including the area is displayed. When an input terminal type that can be assigned to a selector is selected in the connection area in accordance with a user operation, one input terminal is selected for user operation from the plurality of input terminals of the selected type in the input area. Is selected accordingly. When a type of input terminal whose assignment to the selector is predetermined for the connection area is selected, the input area cannot be set according to a user operation. (In other words, in the input area, an input terminal whose assignment to the selector is determined in advance is automatically displayed or the input terminal is not displayed.) The assigning means responds to a user operation in the connection area. When the input terminal type that can be assigned to the selector is selected, the input terminal selected in the input area is assigned to the selector, and the input terminal type assigned to the selector in the connection area is predetermined. When selected, all assignments of assignable input terminals to the selector are canceled according to the user operation.

  In this case, after selecting the type of terminal to be selected by the selector in the connection area, the input terminal to be allocated to the selector is selected in the input area. When the type selected in the connection area is an input terminal whose assignment to the selector is predetermined, the input terminal assigned automatically is displayed in the input area or the input terminal is not displayed (that is, , Is not selectable). As a result, the user does not need to determine which input terminal needs to be assigned to the selector and does not need to perform the operation, and an excellent effect is obtained in that the same operation can be performed for all the input terminals. .

  In a preferred embodiment, the input setting device further includes an allocation table for setting allocation between the selector and the input terminal for each type of input terminal that can be allocated to the selector according to a user operation. When an input terminal type that can be assigned to a selector is selected in response to a user operation in the connection area, the assigning means includes a selector corresponding to the assignment setting screen and the input in the assignment table of the selected type. Set the assignment with the input terminal selected in the area, and set the assignment table other than the type selected in the connection area to release the assignment between the selector corresponding to the assignment setting screen and the input terminal. When a type of input terminal whose assignment to the selector is predetermined in the connection area is selected, all assignment tables are set to release assignment between the selector and the input terminal corresponding to the assignment setting screen. To do.

  In this case, the assigning unit can assign the input terminal to the selector by automatically setting the assignment table based on the setting content of the assignment setting screen. As the allocation table, a conventional one provided for each type of input terminal that can be allocated to the selector according to a user operation can be adopted, so that compatibility with the conventional can be obtained at the time of design. .

  In a preferred embodiment, the input setting device further includes image data storage means for storing image data of a cable to be connected to the input terminal and image data of the input terminal for each type of the input terminal. The allocation setting screen display means includes a cable image display area for displaying a cable image corresponding to the type of the input terminal selected in the connection area, and a terminal image display for displaying an image of the input terminal selected in the input area. An allocation setting screen further including an area is displayed.

  In this case, the user can operate the assignment setting screen while looking at the image of the cable and the input terminal, so that the setting operation is further facilitated.

  In another aspect of the present invention, an input setting program for causing a computer to execute each of the above means may be provided.

  According to the present invention, since assignment setting to a selector can be performed for each selector using an assignment setting screen, the assignment setting operation becomes very easy.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to these embodiments. FIG. 1 is a block diagram showing an amplifying device 1 to which the input setting device of this embodiment is applied. In this embodiment, the video input terminal allocation operation to the selector will be mainly described. However, the audio input terminal allocation operation to the selector is the same.

  The amplifying apparatus 1 includes an input terminal group 2, a selection unit 3, a control unit (hereinafter referred to as a microcomputer) 4, a memory unit (including flash memory, ROM, RAM, etc.) 5, an OSD display unit 6, a video output terminal 7, an audio A processing unit 8, an operation unit 9, and a display unit 10 are provided.

  The input terminal group 2 includes a plurality of video input terminals and a plurality of audio input terminals, to which playback devices (DVD player, VTR, set top box, CD player, etc.) not shown are connected. The video input terminal includes, for example, a composite terminal, an S video terminal, three component terminals (component 1 terminal to component 3 terminal), three D4 terminals (D4-1 terminal to D4-3 terminal), and two HDMI terminals (HDMI1). Terminal to HDMI2 terminal). One composite terminal and one S video terminal are provided for each selector. The audio input terminals include, for example, analog audio terminals, coaxial digital terminals, optical digital terminals, HDMI terminals, and the like.

  The selector 3 selects one video data from video data input to a plurality of video input terminals according to an instruction from the microcomputer 4. The select unit 3 has a plurality of sectors. In this example, there are five selectors: a DVD selector and a video 1 to video 4 selector.

  An arbitrary D4 terminal, component terminal, or HDMI terminal can be assigned to each selector based on a user operation. The assignment is executed by the microcomputer 4 rewriting the contents of the assignment table 5A stored in the memory unit 5.

  When assigning component terminals to selectors, the component assignment table shown in FIG. 2 is used. “IN1”, “IN2”, “IN3”, or “NO” is set in association with each selector. When “IN1” is set, the component 1 terminal is assigned to the selector. When “IN2” is set, the component 2 terminal is assigned to the selector. When “IN3” is set, the selector is assigned to the selector. When the component 3 terminal is assigned and “NO” is set, the component terminal is not assigned to the selector.

  When assigning the D4 terminal to the selector, the D4 assignment table shown in FIG. 3 is used. “IN1”, “IN2”, “IN3”, or “NO” is set in association with each selector. When “IN1” is set, the D4-1 terminal is assigned to the selector. When “IN2” is set, the D4-2 terminal is assigned to the selector. When “IN3” is set, the D4-1 terminal is assigned. When the D4-3 terminal is assigned to the selector and “NO” is set, the D4 terminal is not assigned to the selector.

  When the HDMI terminal is allocated to the selector, the HDMI allocation table shown in FIG. 4 is used. “IN1”, “IN2”, or “NO” is set in association with each selector. When “IN1” is set, the HDMI1 terminal is assigned to the selector. When “IN2” is set, the HDMI2 terminal is assigned to the selector. When “NO” is set, the HDMI terminal is assigned to the selector. Is not assigned.

  On the other hand, the composite terminal and the S video terminal are assigned in advance to each selector, and cannot be assigned to any selector by a user operation. When causing the selector to select the composite terminal or the S video terminal, the microcomputer 4 sets all the corresponding selectors in the allocation tables of FIGS. 2 to 4 to “NO”. It is one of the features of the present invention to set the allocation tables of FIGS. 2 to 4 using only the allocation setting screen of FIG. 5 described later.

  The microcomputer 4 controls each unit of the amplifying apparatus 1 by executing a program stored in the memory unit 5. The microcomputer 4 includes an allocation unit 4A and an OSD control unit 4B. The allocation unit 4A allocates a component terminal, a D4 terminal, or an HDMI terminal to the selector based on a user operation. Alternatively, the allocating unit 4A cancels the allocation of the component terminal, the D4 terminal, or the HDMI terminal to the selector when the selector selects the composite terminal or the S video terminal. To cancel the allocation is to set “NO” in the allocation table. The OSD control unit 4B controls the OSD display unit 6 so that the assignment setting screen shown in FIG.

  FIG. 5 is an assignment setting screen for setting each assignment table of FIGS. The assignment setting screen is displayed for each selector. FIG. 5A shows the assignment setting screen of the DVD selector, and FIG. 5B shows the assignment setting screen of the video 1 selector. Every time the user operates the operation unit 9, the assignment setting screen displayed on the monitor by OSD is switched. That is, at first, the allocation setting screen of the DVD selector is displayed as shown in FIG. 5A, and the allocation setting screen is sequentially displayed in the order of the video 1 selector to the video 4 selector by operating the operation unit.

  The DVD selector shown in FIG. 5A will be described as an example. The assignment setting screen includes a video setting area (hereinafter referred to as VIDEO area) 51, an audio setting area (hereinafter referred to as AUDIO area) 52, a cable image display area 53, and a terminal image display area 54. The VIDEO area 51 includes an area (hereinafter referred to as a CONNECTION area) 51A for setting the type of a video input terminal to be selected by the DVD selector, and an area (hereinafter referred to as an INPUT area) 51B for setting an input terminal assigned to the DVD selector. . Here, the type of the video input terminal represents the type of the terminal such as component, D4, HDMI, composite, S-video. That is, in the CONNECTION area, one type is selected from among the types of input terminals that can be allocated by user operations and the types of input terminals that are predetermined to be allocated to selectors. When the cursor (not shown) is positioned in the CONNECTION area 51A and the RIGHT / LEFT button of the operation unit 9 is pressed, one of these is sequentially selected.

  In the INPUT area 51B, one input terminal is selected by a user operation from a plurality of input terminals corresponding to the type of input terminal selected in the CONNECTION area 51A. For example, as shown in FIG. 5A, when HDMI is set in the CONNECTION area 51A, there are two HDMI terminals. Therefore, either IN1 representing the HDMI1 terminal or IN2 representing the HDMI2 terminal in the INPUT area. Is selected by a user operation. When composite or S-video is set in the CONNECTION area 51A, these terminals are assigned in advance to the selector, so the INPUT area cannot be selected by the user. That is, IN1 indicating an input terminal assigned in advance is automatically displayed in the INPUT area, or “---” indicating that setting cannot be performed as shown in FIG. 5B is displayed. .

  The allocation unit 4A updates the contents of the allocation tables in FIGS. 2 to 4 based on the contents set by the user on the allocation setting screen in FIG. Specifically, when the type selected in the CONNECTION area 51A is a type that can be allocated by a user operation (D4, component, or HDMI), the input terminal selected in the INPUT area 51B in the corresponding selector in the corresponding allocation table And “NO” is set in the corresponding selector of the other allocation table. For example, when HDMI is selected in the CONNECTION area 51A and IN1 is selected in the INPUT area on the DVD selector allocation setting screen of FIG. 5A, the allocation unit 4A displays “IN1” in the DVD selector of the HDMI allocation table shown in FIG. Is set, and “NO” is set in the DVD selector of the component allocation table and the D4 allocation table.

  When the type selected in the CONNECTION area 51A is a type (composite or S-video) pre-assigned to the selector, “NO” is set in the corresponding selector of all assignment tables in FIGS. This is because when the selector is selected, composite or S-video is selected. For example, when the composite is selected in the CONNECTION area 51A on the DVD selector allocation setting screen of FIG. 5A, all of the DVD selectors in the allocation tables of FIGS.

  The cable image display area 53 is an area for displaying an image of a cable corresponding to a video input terminal or a cable corresponding to an audio input terminal. That is, when the cursor is positioned in the VIDEO area, the cable image display area 53 displays a cable image corresponding to the type of the CONNECTION area of the VIDEO area. For example, in the case of FIG. 5A, an HDMI cable image is displayed in the cable image display area 53. When the cursor is positioned in the AUDIO area, the cable image display area 53 displays a cable image corresponding to the type of the CONNECTION area of the AUDIO area.

  The terminal image display area 54 displays the image of the video input terminal set in the INPUT area when the cursor is positioned in the VIDEO area. For example, in the case of FIG. 5A, the HDMI 1 terminal image is displayed in the terminal image display area 54. Similarly, when the cursor is positioned in the AUDIO area, the terminal image display area 54 displays the image of the audio input terminal set in the INPUT area.

  Returning to FIG. 1, the memory unit 5 includes each allocation table 5 </ b> A in FIGS. 2 to 4, cable image data 5 </ b> B for displaying in the cable image display area 53, and terminal image data 5 </ b> C for displaying in the terminal image display area 54. Is stored.

  The memory unit 5 further stores an input terminal number table shown in FIG. The input terminal number table is a table for managing the number of input terminals of each type. For example, 1 is registered for composite and 2 is registered for HDMI. Also, input terminal numbers are set according to the number of input terminals. If the number of input terminals is 1, only input terminal number 1 is input. If the number of input terminals is 2, input terminal numbers 1 and 2 are input. If the number of terminals is 3, input terminal numbers 1, 2, and 3 are set.

  The memory unit 5 further stores a setting status table shown in FIG. The setting status table stores the current setting state of each area based on the user operation on the assignment setting screen of FIG. 5 and is used for each process of the flowchart described later. Specifically, “Cursor” stores whether the current cursor position is in the CONNECTION area or the INPUT area, “Connection” stores the setting contents (each type) of the CONNECTION area, and “Input” INPUT area settings (IN1, IN2, IN3) are stored.

  The memory unit 5 further stores an image table shown in FIG. The image table manages the file name of the cable image data and the file name of the terminal image data in association with the combination of the input terminal type and the input terminal number. The image table is used to select an image to be displayed in the cable image display area and the terminal image display area.

  Returning to FIG. 1 again, the OSD display unit 6 generates the OSD screen of the assignment setting table of FIG. 5 based on the command from the OSD control unit 4B, and sends it to the monitor connected to the outside via the video output terminal 7. Display OSD. The audio processing unit 8 performs D / A conversion, signal processing, amplification processing, and the like on the audio signal input via the audio input terminal, and supplies the audio signal to a speaker (not shown) connected to the outside. The operation unit 9 includes a remote control light receiving unit (and a remote control transmitter), operation buttons provided on the front panel, and the like, and an UP button, a DOWN button, a RIGHT button, Includes LEFT button, ENTER button, etc. The display unit 10 is an LCD, FL tube, or the like, and the OSD control unit 4B can display the assignment setting screen on the display unit 10 instead of displaying the assignment setting screen on the monitor.

  With respect to the amplifying apparatus 1 having the above configuration, the assignment process of the microcomputer 4 will be described with reference to a flowchart. As shown in FIG. 9, the microcomputer 4 sequentially displays an assignment setting screen for each selector and executes assignment setting for each selector. That is, the microcomputer 4 assigns the DVD selector (S51), the video 1 selector (S52), the video 2 selector (S53), the video 3 selector (S54), and the video 4 selector. It performs in order of setting (S54). Hereinafter, the allocation setting of the DVD selector will be described as an example, but the same applies to other selectors. In addition, although the case of a video input terminal will be described as an example, the assignment of audio input terminals is the same.

  As shown in FIG. 10, when the assignment setting screen of FIG. 5A is displayed on the OSD, the microcomputer 4 has pressed the ENTER button (S101), the UP button, or the DOWN button as the main process. (S102, S103) and whether the RIGHT button or LEFT button has been pressed (S104, S105).

  When the ENTER button is pressed (YES in S101), the microcomputer 4 executes a setting determination process (S109) and ends the process. Details of S109 will be described later.

  When the UP button or the DOWN button is pressed, the microcomputer 4 moves the cursor position on the assignment setting screen up and down. Specifically, when the UP button is pressed (YES in S102), the microcomputer 4 executes a cursor up process (S110), and proceeds to S108. Details of S110 are shown in FIG. The microcomputer 4 refers to the setting status table of FIG. 7 to determine the current value of the cursor (S200). If the current value of the cursor is CONNECTION, the microcomputer 4 moves the cursor to the INPUT area (S201), and the current value of the cursor. If is INPUT, the cursor is moved to the CONNECTION area (S202). As the cursor moves, the cursor value in the setting status table is also updated.

  When the DOWN button is pressed (YES in S103), the microcomputer 4 executes a cursor down process (S111), and proceeds to S108. Details of S111 are shown in FIG. The microcomputer 4 refers to the setting status table of FIG. 7 to determine the current value of the cursor (S300). If the current value of the cursor is CONNECTION, the microcomputer 4 moves the cursor to the INPUT area (S301), and the current value of the cursor. If is INPUT, the cursor is moved to the CONNECTION area (S302). As the cursor moves, the cursor value in the setting status table is also updated.

  If the RIGHT / LEFT button is pressed while the cursor is in the CONNECTIN area, the terminal type of the CONNECTIN area is selected. Specifically, if the RIGHT button is pressed when the current value of the cursor is CONNECTION (YES in S104, Connection in S120), the microcomputer 4 executes a connection up process (S112), and proceeds to S108. Details of S112 are shown in FIG. The microcomputer 4 refers to the setting status table of FIG. 7 to determine the current value of the connection (S400). When the current value of the connection is composite, the terminal type is changed to S video and the INPUT area is set to IN1. If the connection is automatically set (S401) and the current value of the connection is S-video, the terminal type is changed to component, the INPUT area is automatically set to the initial value IN1 (S402), and the current value of the connection is component The terminal type is changed to D4, the INPUT area is set to the initial value IN1 (S403), and if the current value of the connection is D4, the terminal type is changed to HDMI and the INPUT area is the initial value. If it is automatically set to IN1 (S404) and the current connection value is HDMI, the terminal type is changed to composite and the INPUT area Is automatically set to IN1 (S405). The connection value in the setting status table is also updated.

  If the LEFT button is pressed when the current value of the cursor is in the CONNECTION area (YES in S105, Connection in S121), the microcomputer 4 executes a connection down process (S113), and proceeds to S108. Details of S113 are shown in FIG. The microcomputer 4 refers to the setting status table of FIG. 7 to determine the current value of the connection (S500). If the current value of the connection is composite, the terminal type is changed to HDMI and the INPUT area is set to the initial value. If it is automatically set to a certain IN1 (S501) and the current value of the connection is S-video, the terminal type is changed to composite, the INPUT area is automatically set to IN1 (S502), and the current value of the connection is a component. The terminal type is changed to S-video, the INPUT area is automatically set to IN1 (S503), and if the current value of the connection is D4, the terminal type is changed to component, and the INPUT area is automatically set to the initial value IN1. Set (S504), if the current value of the connection is HDMI, change the terminal type to D4 and set the INPUT area to the initial value. A certain IN1 is set (S505). The connection value in the setting status table is also updated.

  When the RIGHT / LEFT button is pressed while the cursor is in the INPUT area, the input terminal is selected in the INPUT area. Specifically, when the RIGHT button is pressed when the current value of the cursor is INPUT (YES in S104, Input in S120), the microcomputer 4 executes input up processing (S114), and proceeds to S108. Details of S114 are shown in FIG. The microcomputer 4 refers to the input in the setting status table of FIG. 7 and sets the input setting value to 1 (S600). Next, the microcomputer 4 refers to the input terminal number table in FIG. 6 and determines whether or not the value obtained in S600 exceeds the number of terminals of the type selected in the CONNECTION area (S601). For example, when the type selected in the CONNECTION area is HDMI, it is determined whether or not the input value is 3 as a result of S600. If it exceeds (YES in S601), the microcomputer 4 returns the input value of the setting status table to 1 (S602). In step S603, the input terminal corresponding to the input value in the setting status table is displayed in the INPUT area. Therefore, every time the RIGHT button is pressed, the display is switched in the order of “IN1”, “IN2”, “IN1”,.

  If the LEFT button is pressed when the current value of the cursor is in the INPUT area (YES in S105, Input in S121), the microcomputer 4 executes an input down process (S115), and proceeds to S108. Details of S115 are shown in FIG. The microcomputer 4 refers to the input in the setting status table of FIG. 7 and sets the input setting value to a value obtained by subtracting 1 (S700). Next, the microcomputer 4 determines whether or not the value obtained in S700 is 0 (S701). In the case of 0 (YES in S701), the microcomputer 4 refers to the input terminal number table in FIG. 6 to return the input value in the setting status table to the number of terminals of the type set in the CONNECTION area (S702). . For example, if the CONNECTION area is HDMI, the input value of the setting status table is returned to 2. In step S703, the input terminal corresponding to the input value in the setting status table is displayed in the INPUT area. Therefore, every time the LEFT button is pressed, the display is switched in the order of “IN2”, “IN1”, “IN2”,.

  When the terminal type selected in the CONNECTION area is composite or S-video, referring to FIG. 6, the number of these input terminals is set to 1, so that the user temporarily presses the RIGHT / LEFT button. Even if is pressed, only IN1 is displayed. This is because the allocation of the composite or S video to the selector is determined in advance, and the allocation cannot be changed by the user.

  In S108, the microcomputer 4 refers to the image table of FIG. 8 based on the connection and input values of the setting status table of FIG. 6, and receives the image data of the corresponding cable and the image data of the input terminal from the memory unit 5. Read out and display each image in the cable image display area and terminal image display area.

  Next, the setting determination process in S109 will be described with reference to FIG. In S109, the microcomputer 4 sets each allocation table in FIGS. 2 to 4 in accordance with a user operation based on the allocation setting screen in FIG. 5 (that is, based on the value in the setting status table in FIG. 7). The microcomputer 4 determines the current value of the connection with reference to the setting status table of FIG. 7 (S800). When the connection value in the setting status table is composite or S-video, “NO” is set in the DVD selectors of all allocation tables in FIGS. 2 to 4 (S801). This is because the DVD selector selects composite or S-video by deallocating all components, D4 and HDMI.

  When the connection value in the setting status table is a component, the input value in the setting status table in FIG. 7 is set in the DVD selector in the component allocation table in FIG. 2, and NO is set in the DVD selector in the other (D4 and HDMI) allocation tables. Is set (S802). That is, if the input of the setting status table is 1, IN1 is set in the DVD selector of the component allocation table. Thus, the component 1 terminal is assigned to the DVD selector, and the DVD selector selects the component 1 terminal.

  When the connection value of the setting status table is D4, the input value of the setting status table of FIG. 7 is set to the DVD selector of the D4 allocation table of FIG. 3, and NO is set to the DVD selector of the other (component and HDMI) allocation tables. Is set (S803). That is, if the input of the setting status table is 1, IN1 is set in the DVD selector of the D4 allocation table. Thereby, the D4-1 terminal is assigned to the DVD selector, and the DVD selector selects the D4-1 terminal.

  When the connection value of the setting status table is HDMI, the input value of the setting status table of FIG. 7 is set in the DVD selector of the HDMI allocation table of FIG. 4, and NO is set in the DVD selector of the other (component and D4) allocation tables. Is set (S804). That is, if the input in the setting status table is 1, IN1 is set in the DVD selector of the HDMI allocation table. Thereby, the HDMI 1 terminal is assigned to the DVD selector, and the DVD selector selects the HDMI 1 terminal.

  As described above, in this embodiment, since the assignment setting screen is displayed for each selector, the user selects the type of terminal to be selected by the selector in the CONNECTION area, and then the selected terminal type is assigned by the user. In the case of a possible type, the assignment table of FIGS. 2 to 4 is automatically set only by selecting the input terminal to be assigned to the selector, so that the assignment operation becomes very easy. That is, there is no need to display a plurality of allocation tables in OSD and change them individually by user operation. For example, when changing the allocation of the DVD selector from the HDMI 1 terminal to the component 2 terminal, the user only has to change the CONNECTION area of the allocation setting screen from HDMI to the component, and change the INPUT area from IN1 to IN2. Further, when changing the allocation of the DVD selector from the HDMI1 terminal to the composite terminal, the user only has to change the CONNECTION area of the allocation setting screen from HDMI to composite.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. The cable image display area and the terminal image display area may display both video and audio cables and terminals simultaneously. Instead of the assignment tables of FIGS. 2 to 4, as shown in FIG. 18, selectors may be set in association with input terminals. The operation for assigning audio input terminals is the same. In this case, the audio area can be selected by moving the cursor up and down and the same operation can be performed. Further, in this example, the allocation is performed by setting the above allocation table based on the setting status of the allocation setting screen. However, the allocation setting screen itself of FIG. 5 may be used as the allocation table. That is, according to the present invention, it is only necessary for the user to perform assignment setting using the assignment setting screen, and the assignment processing itself is not limited to the above example. The present invention can also be provided in the form of a computer program for causing a computer to execute the above operations.

  The present invention can be suitably employed in an AV amplifier.
