Incidentally, the relays 43 ₁ to 43 ₈ , for example, can also block the output to the unused speaker 4 by a command given from the operation input unit 11, and thereby, the used speaker 4 and the unused speaker 4 can be disconnected. It can be used properly.

(3) Specific Processing Contents of Control Unit Next, specific processing contents of the control unit 10 in the home server 2 will be described. The control unit 10 includes a display unit based on control data provided from the operation input unit 11 or the interface 12 and setting data D1 stored in the data storage medium 13 in accordance with the basic program and various application programs stored in the ROM. 14. Various processes are executed by appropriately controlling the graphic processing unit 15, the digital signal processing unit 16, the distribution processing unit 17, and the analog signal processing unit 18.

(3-1) Reproduction Process When the control data representing a reproduction command is given from the operation input unit 11, for example, the control unit 10 is a DVD player 3A, CD player 3B, or portable music player that is the target of this reproduction command. 3C is driven for playback control, character data representing the content is generated based on content information supplied from the DVD player 3A, CD player 3B, or portable music player 3C, and characters corresponding to the character data are generated. Is displayed on the FL tube 14 and the LCD 5.

  In addition, during playback of the DVD player 3A, the control unit 10 displays a video image based on the video signal supplied from the DVD player 3A on the LCD 5 (FIG. 1) via the graphic processing unit 15. Incidentally, during the reproduction of the CD player 3B or the portable music player 3C, the control unit 10 generates an image suitable for each source by the graphic processing unit 15 and displays it on the LCD 5.

  Actually, the control unit 10 of the home server 2 generates a home screen HM as shown in FIG. 3 by the graphic processing unit 15 when the power is turned on, and displays this on the LCD 5. In this home screen HM, a “video” icon AC1, a “music” icon AC2, and a “settings” icon AC3 are arranged in the highest hierarchy.

  When the “video” icon AC1 on the home screen HM is selected and determined, the control unit 10 displays a video image VS corresponding to the video signal supplied from the DVD player 3A on the LCD 5, as shown in FIG.

  Further, when the “music” icon AC2 on the home screen HM is selected and determined, the control unit 10, as shown in FIG. 5, for example, is a notification screen made up of characters “NOW PLAYING” that is unrelated to the playback sound of the CD player 3B. N1 is generated by the graphic processing unit 15 and displayed on the LCD 5, or as shown in FIG. 6, a notification screen N2 including the playback track number, playback elapsed time, artist name, album name, etc. of the portable music player 3C Is generated by the graphic processing unit 15 and displayed on the LCD 5.

(3-2) Sound field setting process When the control data representing the sound field setting command is given from the operation input unit 11, for example, the control unit 10 stores the setting data D1 and the setting screen data stored in the data storage medium 13. The GUI screen data D3 based on D2 is generated via the graphic processing unit 15, and a GUI screen corresponding to the GUI screen data D3 is displayed on the LCD 5 (FIG. 1).

  And when the setting change command for each speaker 4 arranged in the sound field space is given from the operation input unit 11 according to the operation of the remote controller RCL or the like, the control unit 10 according to the content of the setting change command, The contents of the setting data D1 stored in the data storage medium 13 are rewritten.

  When the content of the setting change command is content related to a sound image, the control unit 10 sends a predetermined test sound from the speaker 4 so that when the setting change command is given, a sound image corresponding to the setting change command is obtained. While outputting the sound image as an image on the LCD 5 (FIG. 1), the sound image can be expressed audibly and visually.

(3-3) Zone setting process In the case of this embodiment, in the home server 2, each speaker 4 (4FL, 4FR, 4CT, 4SL, 4SR, 4SBL, 4SBR and 4SW) is connected to, for example, a listening room, a kitchen, and a child room. Are assigned as a plurality of groups for each sound field space, etc., and different reproduction sounds or the same reproduction sounds can be output from the speakers 4 belonging to the group.

  Therefore, the home server 2 can centrally manage sound field correction in units of zones by arranging the speakers 4 belonging to each group in different sound field spaces and recognizing each sound field space as a zone. It is made like that.

(4) Zone setting method using GUI In this AV system 1, the listening room, the kitchen, and the child room are each considered as one sound field space, that is, a zone, and the listening room has a left front speaker 4FL and a right front. The speaker 4FR, the center speaker 4CT, and the subwoofer 4SW are arranged, the left surround speaker 4SL and the right surround speaker 4SR are arranged in the kitchen, and the left surround back speaker 4SBL and the right surround back speaker 4SBR are arranged in the child room. Has been made.

  Incidentally, the arrangement pattern of the speakers 4 is not limited to this, and may be a combination of other various combinations.

  The home server 2 of the AV system 1 regards the listening room as the main zone, regards the kitchen as zone 2 and the child room as zone 3, sets the speakers for the main zone, zone 2 and zone 3, types of contents to be distributed, Various settings such as on / off settings relating to a predetermined function are individually performed on the GUI screen of the LCD 5, and the setting contents of these multi-zone setting processes are displayed in a list on the GUI screen.

  In practice, the control unit 10 of the home server 2 can easily execute the multi-zone setting process on the GUI screen displayed on the LCD 5. In this case, the “setting” icon AC 3 (see FIG. 3) is selected, and a “multi-zone setting” icon AC4 in the lower hierarchy is selected and determined.

  In this case, the control unit 10 displays the multi-zone distribution status list screen MZD1 generated by the graphic processing unit 15 on the LCD 5, as shown in FIG. In the multi-zone distribution status list screen MZD1 (FIG. 7), input source items (“Input”), main zone (“Main”), zone 2 (“Zone 2”), and zone 3 (“Zone 3”), A list of volume level items (“Volume”) and device control items (“12V Trigger”) that automatically supply operation commands to various devices connected to the home server 2 are displayed.

  The multi-zone distribution status list screen MZD1 (FIG. 7) shows a state where the main zone (“Main”) is focused (shaded), that is, the main zone (“Main”). )) Can be visually recognized by the user that it is a setting target of the setting process.

  The input source item ("Input") lists the types of input sources distributed to the main zone ("Main"), zone 2 ("Zone2") and zone 3 ("Zone3"), respectively. In this case, “DVD” indicating the DVD player 3A is displayed in the main zone (“Main”), and “Music Player” indicating the portable music player 3C is displayed in the zone 2 (“Zone 2”). In the zone 3 (“Zone 3”), “CD” indicating the CD player 3B is displayed.

  Therefore, the user managing the home server 2 outputs the audio of the DVD played by the DVD player 3A to the main zone (living room) via the multi-zone distribution status list screen MZD1 (FIG. 7), and outputs the zone 2 ( It is possible to recognize at a glance that audio of music reproduced by the portable music player is output to the kitchen) and that CD audio reproduced by the CD player 3B is output to the zone 3 (child's room). Has been made.

  The volume level item (“Volume”) indicates the absolute value of the volume level output for each of the main zone (“Main”), zone 2 (“Zone 2”), and zone 3 (“Zone 3”). In this case, “−20.0 dB” is displayed in the main zone (“Main”), “−30.5 dB” is displayed in Zone 2 (“Zone 2”), and CD is displayed in Zone 3 (“Zone 3”). Since the power of the player 3B is OFF, nothing is displayed.

  The device control item (“12V Trigger”) is a function assigned only to the main zone, and “INPUT” or “OFF” is displayed. Only when this device control item (“12V Trigger”) is set to “INPUT”, the input trigger setting display field AR1 is displayed on the right side of the multi-zone distribution status list screen MZD1 (FIG. 7), and “OFF” is displayed. Is set, the input trigger setting display field AR1 is not displayed.

  Here, the function of the device control item (“12V Trigger”) refers to another device related to the DVD player 3A indicated by “DVD” connected to the home server 2 as an input source item (“Input”). It is to output a command signal (12V) for automatically starting up via the home server 2.

  That is, when the device control item (“12V Trigger”) is set to “INPUT”, the input source (“VIDEO1” to “VIDEO3”, “DVD”, “Music Player”, “CD” in the input trigger setting display field AR1. If “ON” is set for “MD”), when the input source is connected to the home server 2, a command signal (12 V) is output to another device related to the input source. However, if “OFF” is set, the command signal (12 V) is not output.

  Specifically, for example, when a projector and a screen are connected to the home server 2 as other devices related to the DVD player 3A, the home server 2 automatically turns on when the DVD player 3A in the main zone is turned on. Since the command signal (12V) is supplied to the projector and the screen, the projector and the screen related to the DVD player 3A are automatically set up without bothering the user.

  In addition, the control unit 10 of the home server 2 receives the playback video data from the DVD player 3A in the main zone (“Main”), and the track number, title, and playback target data from the portable music player 3C in the zone 2 (“Zone 2”). Attribute information such as artist name is received, and attribute information such as CD title and artist name is received from the CD player 3B of zone 3 (“Zone 3”), and the multi-zone distribution status list screen MZD1 (FIG. 7). , The video relating to the content to be output is generated in the main zone (“Main”), zone 2 (“Zone 2”) and zone 3 (“Zone 3”), respectively, and these are displayed on the small window screens WS1, WS2 and WS3. It is made like that.

  As a result, on the small window screen WS1 corresponding to the main zone (“Main”), the playback video of the DVD player 3A corresponding to “DVD” connected as the input source item (“Input”) is displayed, and the zone 2 ( In the small window screen WS2 corresponding to “Zone2”), the video of the track number that is the reproduction target of the portable music player 3C corresponding to “Music Player” connected as the input source item (“Input”) is displayed, On the small window screen WS3 corresponding to the zone 3 (“Zone 3”), the CD video of the CD player 3B corresponding to “CD” connected as the input source item (“Input”) is displayed.

  As a result, the user managing the home server 2 determines what kind of content the user in the main zone (“Main”) is viewing and what kind of title the user in the zone 2 (“Zone 2”) has. Whether the CD of the title is scheduled to be listened to or has already been listened to, even if the user in zone 3 (“Zone 3”) is not actually listening Can be checked.

  While the multi-zone distribution status list screen MZD1 (FIG. 7) is being displayed, the control unit 10 is shown in FIG. 8 in response to a user pressing operation on the “Enter” key and the two “→” keys of the remote controller RCL. The display of the LCD 5 is switched to the multi-zone distribution status list screen MZD2 in which only the device control item (“12V Trigger”) is focused.

  In this case, the control unit 10 has pressed the “↓” key of the remote controller RCL in accordance with the down key DWK of the device control item (“12V Trigger”) on the multi-zone distribution status list screen MZD2 (FIG. 8). Is recognized, the “INPUT” of the device control item (“12V Trigger”) on the multi-zone distribution status list screen MZD1 (FIG. 7) is changed to the device control item (“12V” on the multi-zone distribution status list screen MZD2 (FIG. 8). “Trigger”) is switched to “OFF”.

  When the device control item (“12V Trigger”) is switched to “OFF”, the control unit 10 displays the input trigger setting display field AR1 of the multi-zone distribution status list screen MZD1 (FIG. 7) in the multi-zone distribution status. It is removed from the list screen MZD2 (FIG. 8), and the text “12V trigger is always turned OFF” is used for the comment field CM1 as an explanatory text during the parameter change. 8) is displayed.

  Note that the control unit 10 also applies to the multi-zone distribution status list screen MZD2 (FIG. 8) via the small window screens WS1, WS2, and WS3, similarly to the multi-zone distribution status list screen MZD1 (FIG. 7). A video related to the content being distributed can be displayed in the zone.

  By the way, the control unit 10 displays an input trigger setting display field as shown in FIG. 9 in response to a user pressing operation on the “→” key of the remote controller RCL while the multi-zone distribution status list screen MZD1 (FIG. 7) is displayed. The display of the LCD 5 is switched to the multi-zone distribution status list screen MZD3 focused only on the source item of AR1 (in this case, “VIDEO1 ON”).

  In the multi-zone distribution status list screen MZD3 (FIG. 9), the source item (“VIDEO1 ON”) in the input trigger setting display field AR1 is in focus, and the comment field CM2 is displayed with “Input”. In conjunction with switching, the 12V trigger is turned ON / OFF. ON / OFF can be set for each input. ”The character (ON / OFF) of the source item (“ VIDEO1 ON ”) is changed. It is displayed as an explanatory text indicating whether or not the effect is exhibited.

  The control unit 10 can sequentially switch the source items in the input trigger setting display field AR1 in the vertical direction in accordance with the user's pressing operation on the “↑” key or “↓” key of the remote controller RCL.

  Then, while the multi-zone distribution status list screen MZD3 (FIG. 9) is displayed, the control unit 10 focuses on the main zone (“Main”) in response to the user's pressing operation on the “←” key of the remote controller RCL. The display on the LCD 5 is returned to the assigned multi-zone distribution status list screen MZD1 (FIG. 7).

  Subsequently, while the multi-zone distribution status list screen MZD1 (FIG. 7) is being displayed, the control unit 10 performs multi-zone distribution as shown in FIG. 10 in response to two pressing operations on the “↓” key of the remote controller RCL. The display of the LCD 5 is switched to the state list screen MZD4.

  This multi-zone distribution status list screen MZD4 (FIG. 10) shows a state in which zone 3 (“Zone 3”) is focused (shaded), that is, zone 3 (“Zone 3”). )) Can be visually recognized by the user that it is a setting target of the setting process.

  Here, since the power source of the zone 3 (“Zone 3”) is off and the control unit 10 has no effect even if the parameter is changed as the setting target of the setting process, the input source item (“Input”) and the volume Since nothing is displayed for the level item (“Volume”), a setting error due to an erroneous operation by the user can be prevented in advance.

  Incidentally, even when the change of the parameter itself is prohibited in the first place, the control unit 10 does not display such items from the beginning, and prevents the user from operating such items. Has been made.

(5) Operation and Effect In the above configuration, the home server 2 of the AV system 1 uses the main zone (“Main” on the multi-zone distribution status list screen MZD1 (FIG. 7) to the multi-zone distribution status list screen MZD1 (FIG. 10). )), The setting contents for all the zones including the zone 2 (“Zone 2”) and the zone 3 (“Zone 3”) can be visually confirmed to the user at a time. Compared with the case where various settings are made for each zone using only the FL pipe 14 having a poor display capability, the operability is further improved while the setting contents are simultaneously viewed and understood.

  When the home server 2 switches the parameter for the device control item (“12V Trigger”) of the main zone (“Main”) in the multi-zone distribution status list screen MZD2 (FIG. 8) to “OFF”, the comment field CM1 is displayed. By displaying the meaning of the parameter change as an explanatory text, the user who has read the explanatory text can instantly understand the effect of the parameter change and without having the user read the instruction manual etc. The next intuitive operation can be executed immediately on the spot.

  Further, when the home server 2 is effective by changing the parameter (ON / OFF) for the source item in the input trigger setting display field AR1 on the multi-zone distribution status list screen MZD3 (FIG. 9), the home server 2 comments Displayed in the column CM2.

  On the other hand, in the home server 2, the power of the zone 3 (“Zone 3”) in the multi-zone distribution status list screen MZD4 (FIG. 10) is in the off state, and changing the parameter as the setting target for the setting process has no effect. In this case, the input source item (“Input”) and the volume level item (“Volume”) are not displayed at all, and a setting error due to an erroneous operation by the user is prevented.

  In the home server 2, the volume level item (“Volume”) of the portable music player 3C is changed by the user in the zone 2 (“Zone 2”), or the volume of the CD player 3B is changed by the user in the zone 3 (“Zone 3”). Even if the level item (“Volume”) is changed, the change result is received from the portable music player 3C or the CD player 3B, and the change result is reflected in the multi-zone distribution status list screens MZD1 to MZD4. Thus, various setting contents in all zones can be easily managed.
