The CPU 11 displays an individual setting screen (not shown) for generating the individual
information 23 on the touch panel 13, and receives selection of any one of the output terminals
16a to 16d (step S11). Hereinafter, the case where the output terminal 16a is selected will be
described as an example.
[0031]
When the output terminal 16a is designated (Yes in step S11), the CPU 11 receives the selection
of the input terminal (individual source) connected to the selected output terminal 16a (step
S12). When the input terminal 15b is selected (Yes in step S12), the CPU 11 registers the
selected input terminal 15b in the column of the individual source of the individual information
23a (step S13).
[0032]
The CPU 11 receives the specification of the volume on the individual setting screen (step S14).
When the user designates the volume "10" (Yes in step S14), the CPU 11 registers the designated
volume "10" in the field of the individual volume of the individual information 23a (step S15).
This completes the creation of the individual information 23a.
[0033]
When the end of the creation of the individual information is instructed (Yes in step S16), the
CPU 11 ends the process shown in FIG. If it is instructed to continue the generation of the
individual information 23 (No in step S16), the CPU 11 returns to step S11, and accepts the
selection of the output terminal.
[0034]
[2.2. Creation of Group Information 22] FIG. 4 is a diagram showing the group information
22 in a table format. Referring to FIG. 4, group information 22 includes group ID (IDentifier),
group source, group volume, start time, group member, and exclusion flag.
09-05-2019

[0035]
The group ID is unique information assigned to the group information 22. Although one group
information 22 is stored in the flash memory 14 in FIG. 1, a plurality of group information 22
may be stored. In this case, the group ID is used to identify each group information 22.
[0036]
Group members indicate output terminals that constitute a group. Two or more output terminals
are designated as group members. In the example shown in FIG. 4, the output terminals 16a and
16c are designated as group members.
[0037]
The exclusion flag indicates whether the output terminal designated as a group member is
temporarily excluded from the group member. The exclusion flag is set for each group member.
The exclusion flag 1 corresponds to the group member 1 (output terminal 16a), and is set to
“0” indicating not to exclude. The exclusion flag 2 corresponds to the group member 2 (output
terminal 16c), and is set to "0". In the group information 22, the output terminal designated as a
group member and the exclusion flag of the output terminal are repeatedly set.
[0038]
The group source indicates an input terminal connected to an output terminal designated as a
group member. In FIG. 4, the input terminal 15 b is designated as a group source. The number of
input terminals designated as a group source is one.
[0039]
The group volume indicates the volume of the content supplied from the output terminal
09-05-2019
10
designated as a group member. In FIG. 4, "10" is designated as the group volume.
[0040]
The start time indicates the time to start control of the output terminal based on the group
information 22. In FIG. 4, “7:00” is designated as the start time. In this case, the AV amplifier 1
controls the selector 17 to connect the output terminals 16a and 16c to the input terminal 15b
when the time “7:00” comes, and the content supplied from the output terminals 16a and 16c
is Adjust the volume to "10". As a result, the user can stream the music to be reproduced by the
CD player 2 from the speakers 4a and 4c connected to the output terminals 16a and 16c at the
specified start time "7:00".
[0041]
FIG. 5 is a flowchart showing the operation of the AV amplifier 1 for creating the group
information 22. FIG. 6A is called a group member selection screen (hereinafter referred to as
“selection screen”) displayed on the touch panel 13. 6B is a diagram showing a selection
screen on which the user's operation is reflected.
[0042]
When the user instructs creation of the group information 22, the CPU 11 starts the process
shown in FIG. Referring to FIG. 5, CPU 11 causes touch panel 13 to display a selection screen
shown in FIG. 6A in order to receive selection of a group member (step S21). At this time, the
CPU 11 issues a group ID, and writes the issued ID in the column of the group ID of the group
information 22.
[0043]
The user operates the selection screen displayed on the touch panel 13 to designate an output
terminal to be registered as a group member. Referring to FIG. 6A, a list (zone list) of output
terminals 16a to 16d is arranged on the left side of the selection screen. A list (member list) of
output terminals selected as group members is arranged on the right side of the selection screen.
09-05-2019
11
The user selects the output terminals 16a and 16c as group members by dragging and dropping
the output terminals 16a and 16c in the zone list onto the member list. As a result, as shown in
FIG. 6B, the output terminals 16a and 16c move from the zone list to the member list. The output
terminals 16b and 16d remain arranged in the zone list.
[0044]
When the output terminals 16a and 16c move to the member list, the CPU 11 determines that
the output terminals 16a and 16c have been selected as group members (Yes in step S22). The
CPU 11 registers the selected output terminals 16a and 16c as group members in the group
information 22 (step S23). In the group information 22, the exclusion flag corresponding to each
of the output terminals 16a and 16c is set to "0". The change of the exclusion flag will be
described later.
[0045]
Next, the CPU 11 displays a group source selection screen (not shown) and receives selection of
an input terminal (group source) connected to a group member (step S24). When the user selects
the input terminal 15b (Yes in step S24), the CPU 11 registers the selected input terminal 15b in
the group information 22 as a group source (step S25).
[0046]
The CPU 11 displays a sound volume designation screen (not shown) and accepts specification of
the volume of the content supplied from the group member (step S26). When the user designates
the volume "10" (Yes in step S26), the CPU 11 registers the designated volume "10" as the group
volume in the group information 22 (step S27).
[0047]
The CPU 11 displays an activation time designation screen (not shown) and accepts designation
of the activation time (step S28). When the user designates the time "7:00" (Yes in step S28), the
CPU 11 registers the designated time "7:00" as the start time in the group information 22 (step
09-05-2019
12
S29), as shown in FIG. End the process. The specification of the start time may be omitted.
[0048]
Also, the user can change the content of the group information 22. The user causes the touch
panel 13 to display the group information 22 to be changed. FIG. 7 is a diagram showing a group
member change screen. Referring to FIG. 7, the configuration of the change screen is basically
the same as the configuration of the selection screen (see FIGS. 6A and 6B).
[0049]
The user can operate the change screen to change the configuration of group members arranged
in the member list. The operation method of the change screen is the same as the operation
method of the selection screen. For example, the user may newly add the output terminal 16d to
the member list, or may replace the output terminal 16b with the output terminal 16c.
[0050]
In the change screen, a check box 31 is provided for each output terminal in the member list. The
check box 31 is disposed on the right side of the member list. The user can temporarily exclude
the output terminal 16a from the group members by checking the check box 31 located on the
right side of the output terminal 16a. In the group information 22, the exclusion flag
corresponding to the output terminal 16a is changed from "0" to "1". The user can cancel the
temporary exclusion of the output terminal 16a by unchecking the check box 31 located to the
right of the output terminal 16a. In this case, in the group information 22, the exclusion flag
corresponding to the output terminal 16a is changed from "1" to "0". A check box 31 may be
provided on the selection screen shown in FIGS. 6A and 6B. It is also possible to change group
source, group volume, and start time.
[0051]
[2.3. Control of Selector 17 and Volume Adjustment] Control of the selector 17 based on
the group information 22 and volume adjustment will be described below. FIG. 8 is a flowchart
09-05-2019
13
showing the operation of the AV amplifier 1 when the content is input to the input terminal.
[0052]
Hereinafter, the operation of the AV amplifier 1 will be described by taking the case where the
CD player 2 supplies audio content to the input terminal 15b as an example. It is assumed that
the AV amplifier 1 operates based on the group information 22 shown in FIG.
[0053]
Referring to FIGS. 4 and 8, when input terminal 15b receives audio content, CPU 11 starts the
process shown in FIG. The CPU 11 determines whether the input terminal 15b is designated as a
group source (step S31).
[0054]
Since the input terminal 15b is designated as a group source in the group information 22 (Yes in
step S31), the CPU 11 executes group control (step S32). Group control is processing for
executing control of the selector 17 and adjustment of the volume based on the group
information 22. The details of group control will be described later. Note that output terminals
that are not targets of group control are determined as targets of individual control, as described
later.
[0055]
On the other hand, when the input terminal 15b is not designated as a group source (No in step
S31), the CPU 11 determines to individually control all of the output terminals 16a to 16d (step
S33). The individual control is a process of executing the control of the selector 17 and the
adjustment of the volume based on the individual information 23. The CPU 11 executes
individual control (step S34), and ends the process shown in FIG. Details of the individual control
will be described later.
09-05-2019
14
[0056]
[2.4. Group Control (Step S32)] FIG. 9 is a flowchart of the AV amplifier 1 that executes
group control (step S32). Group control will be described in detail with reference to FIGS. 4 and
9.
[0057]
The CPU 11 selects a group member (output terminal 16a) with reference to the group
information 22 (step S321). Based on the exclusion flag, the CPU 11 determines whether the
selected output terminal 16a (selected member) is temporarily excluded from the group
members (step S322).
[0058]
As shown in FIG. 4, the exclusion flag of the output terminal 16 a is set to “0” indicating no
exclusion (No in step S 322). The CPU 11 controls the selector 17 to connect the output terminal
16a to the group source (the input terminal 15b) (step S323). The CPU 11 adjusts the volume of
the content supplied from the output terminal 16a to the speaker to the group volume (step
S324).
[0059]
Since all the group members have not been selected (No in step S325), the CPU 11 returns to
step S321 to select the next group member. The output terminal 16c is selected (step S321).
Since the exclusion flag of the output terminal 16c is set to “0” (No in step S322), the output
terminal 16c is connected to the group source by the selector 17 (step S323). The volume of the
output terminal 16c is adjusted to the group volume (step S324).
[0060]
If all group members have been selected (Yes in step S325), the CPU 11 determines output
terminals other than the group members as targets of individual control (step S327), and ends
the processing shown in FIG.
09-05-2019
15
[0061]
Thus, based on the group information 22, the CPU 11 controls the selector 17 to connect the
output terminal designated as the group member to the group source, and sets the volume of the
output terminal designated as the group member to the group volume. adjust.
The user can set desired two or more output terminals collectively by specifying desired two or
more output terminals as a group member.
[0062]
The description will return to the description of step S322. When the exclusion flag of the output
terminal 16a is set to “1” indicating temporary exclusion (Yes in step S322), the CPU 11
determines the output terminal 16a as a target of individual control (step S326). .
[0063]
[2.5. Individual Control] FIG. 10 is a flowchart of the AV amplifier 1 that executes
individual control. The individual control will be described in detail with reference to FIGS. 2 and
10.
[0064]
The CPU 11 selects one output terminal not yet connected to the input terminal among the
output terminals determined to be targets of individual control (step S341). In step S341, it is
assumed that the output terminal 16b not designated as a group member is selected.
[0065]
09-05-2019
16
The CPU 11 controls the selector 17 to connect the output terminal 16b to the individual source
(input terminal 15c) specified by the individual information 23b with reference to the individual
information 23b corresponding to the output terminal 16b (step S342). The CPU 11 adjusts the
volume of the output terminal 16b to the individual volume "6" specified by the individual
information 23b (step S343).
[0066]
The CPU 11 determines whether all the output terminals are connected to any one of the input
terminals 15a to 15d (step S344). When all the output terminals are not connected (No in step
S344), the CPU 11 returns to step S341. On the other hand, when all the output terminals are
connected (Yes in step S344), the CPU 11 ends the process shown in FIG.
[0067]
As described above, the target of individual control includes the output terminal temporarily
excluded from the group member in the group information 22. For example, referring to FIGS. 4
and 9, when the exclusion flag of output terminal 16c is set to "1" (Yes in step S322), output
terminal 16c is temporarily excluded from the group members, and is individually The target of
control is determined (step S326). In this case, the output terminal 16c is connected to the
individual source (input terminal 15a) specified by the individual information 23c in the
individual control process (see FIG. 10), and the volume of the output terminal 16c is specified by
the individual information 23c. Adjusted to volume.
[0068]
Since the group information includes the exclusion flag, the user can temporarily control the
output terminals designated by the group members individually without removing the output
terminals designated by the group members from the group. For example, when the user wants
to temporarily change the audio content output from the speaker 4c, the user may set the
exclusion flag of the output terminal 16c designated as a group member to "1".
[0069]
09-05-2019
17
In the above embodiment, an example in which the output terminal whose exclusion flag is set to
“1” in the group information 22 is connected to an individual source and the volume of the
output terminal is adjusted to an individual volume has been described. It is not limited. The CPU
11 may connect the output terminal whose exclusion flag is set to “1” to the group source, and
adjust the volume of the output terminal to an individual volume.
[0070]
Although the AV amplifier 1 has been described as an example of the content relay device in the
above embodiment, the present invention is not limited to this. The content relay device may be
an AV receiver. That is, the content relay apparatus supplies one or more input terminals for
receiving the content supplied from the content supply device and one or more of the contents
received by the one or more input terminals to the external apparatus. And a selector for
connecting each of the plurality of output terminals to one of the one or more input terminals.
[0071]
Although the example in which the CD player or the DVD player supplies the audio content to the
