First, the configurations of the AV apparatus (0210) and the AV apparatus will be described.
Specific examples of the "AV device" (0200) include various television devices such as liquid
crystal televisions and plasma televisions, component devices such as home theaters, car
navigation devices, car audio devices, and the like. These AV devices are usually installed at the
user's home constantly or are incorporated in a mobile unit as an on-vehicle device, and it is
possible to output an audio signal at a large volume, such an AV device On the other hand, by
connecting the mobile audio device, it becomes possible to listen to the music stored in the
mobile audio device in a powerful acoustic environment.
[0014]
The "audio signal acquisition unit" (0211) acquires an audio signal from the mobile audio device.
The audio signal acquisition unit is configured of, for example, an external audio signal input
terminal, an amplifier, and the like. As a timing for acquiring an audio signal, an audio signal may
be acquired with the insertion of a plug from a mobile audio device as a trigger into an external
audio signal input terminal, or a plug may be inserted into an external audio signal input
terminal. The audio signal may be acquired using the switching process of the input mode of the
AV apparatus as a trigger. The audio signal acquired in this manner is an audio signal output
from the AV apparatus. FIG. 3 is a view showing an example of a schematic view of the AV
apparatus when acquiring an audio signal. In FIG. 3, an AV signal input unit (0304) for inputting
an AV signal acquired internally via a tuner (0303) is connected to an audio signal transfer unit
(0307) by a switch (0305). The audio signal transfer unit (0307) transfers the AV signal as an
audio signal to the audio signal processing circuit (0308). Here, when the plug (0301) from the
mobile audio device is inserted into the external audio signal input terminal (0302) which is an
audio signal acquisition unit, the switch control unit (0306) switches the switch (0305) to an AV
signal input unit. A process of switching from (0304) to the external audio signal input terminal
(0302) is performed. Thereby, the audio signal input from the mobile audio device becomes an
audio output signal from the AV device. The AV apparatus may have the "television broadcast

such as “,” and control related to the setting of the mobile audio device such as “setting”.
These control information may be acquired to match the control information of each mobile
audio device. That is, the control information table on the control information of the
manufacturer of the mobile audio device is held in the AV device, and the control information
suitable for the mobile audio device is selected based on the device identification information of
the connected mobile audio device. It can be output. FIG. 4B is a diagram showing an example of
the control information table. For example, in the example shown in FIG. 4A, "0010" indicating
"2" as the digital signal is the control information for the mobile audio device in the case of
indicating "playback", but for the mobile audio device of another company. In some cases, the
digital signal indicating "reproduction" may be, for example, "0100" indicating "4". The control
information table as shown in FIG. 4B is described on the assumption that the specifications of
manufacturers of mobile audio devices are different, and, for example, in the case where common
specifications are maintained, Control information according to the common specification may be
acquired. The control information may be acquired, for example, by a user pressing a physical
button such as a ten key as a trigger, or may be acquired as a trigger by operating an icon or a
character of a GUI described later.
[0016]
The "control information output unit" (0213) outputs the acquired control information to the
mobile audio device. As a method of outputting control information to the mobile audio device,
for example, output via a USB cable can be mentioned. That is, as a specific example of the
control information output unit, there is a USB port. Control information can be output to various
types of mobile audio devices by using the USB port. In addition to the USB port, the control
information output unit may be, for example, an insertion unit of an optical cable, and for
performing near field data communication such as Bluetooth (registered trademark) or IrDA
(Infrared Data Association). It may be a signal output unit that outputs a signal. Alternatively, the
control information output unit may be configured to be shared with the audio signal acquisition
unit. For example, when an AV device acquires an audio signal from a mobile audio device, when
the audio signal is acquired as a digital signal via a USB, an optical cable, or the like, control
information is sent to the mobile audio device using these. May be configured to be able to
output

Next, each configuration of the mobile audio device will be described. The "audio signal output
unit" (0221) outputs an audio signal to the AV apparatus. Specific examples of the audio signal
output unit include a headphone terminal and a line terminal for audio output. As a method of
outputting an audio signal to an AV apparatus, as already described, audio is input by inputting a
plug of a cable connected to a headphone terminal or a line terminal of a mobile audio apparatus
to an external audio signal input terminal of the AV apparatus It can output a signal. Further, the
audio signal may be output to the AV apparatus as it is as a digital audio signal through the AV
apparatus and the USB or an optical cable. The audio signal output in this manner is used for
audio output from the AV apparatus.

The “control information accepting unit” (0222) accepts control information from the AV
device. The control information accepting unit is configured of an interface for accepting
information from the USB cable, Bluetooth (registered trademark) or IrDA described above. The
“control unit” (0223) controls itself based on the received control information. The "self" is the
mobile audio device itself. "By control information" means based on the control information.
Since the control information is information for controlling the mobile audio device, the control
of the mobile audio device is performed based on the control information. Examples of control of
the mobile audio device include various controls such as power on / off, playback of audio
content, stop, fast-forward, etc., sound quality of audio content, adjustment of volume, setting of
repeat function, and the like. The control unit is configured of, for example, a CPU, a digital signal
processor (DSP), and a read only memory (ROM).

[0031]
Third Embodiment Outline of Third Embodiment In the mobile audio system according to the
08-05-2019
11
third embodiment, the AV apparatus has a display, and the control information is displayed using
a GUI (Graphical User Interface) displayed on the display. It is characterized in that it can be
obtained.
[0032]
<Configuration of Third Embodiment> FIG. 10 shows an example of a functional block in the
present embodiment.
The “mobile audio system” (1000) of the present embodiment shown in FIG. 10 includes “AV
device” (1010), “mobile audio device” (1020), and “remote control device” (1030).
The AV device (1010) includes an "audio signal acquisition unit" (1011), a "control information
acquisition unit" (1012), a "control information output unit" (1013), and a "display" (1014). . The
control information acquisition unit (1012) has “control information acquisition GUI display
means” (1015). The mobile audio device (1020) includes an "audio signal output unit" (1021), a
"control information reception unit" (1022), and a "control unit" (1023). The remote control
device (1030) includes a "control information input unit" (1031) and a "control information
transmission unit" (1032).
[0033]
This embodiment is characterized in that the AV apparatus in the mobile audio system described
in Embodiment 1 or 2 further includes a "display" (1014) and a "control information acquisition
GUI display means" (1015). It is. The components other than the “display” (1014) and the
“control information acquisition GUI display means” (1015) are the same as those described in
the first or second embodiment, and thus the description thereof is omitted here.
[0034]
The "display" (1014) is for outputting AV content. The “AV content” includes, for example,
various contents such as television broadcast programs, movies and music videos stored in DVDs
and videos. The display may be, for example, a liquid crystal display, a CRT (Cathode Ray Tube)
08-05-2019
12
display, a plasma display or an organic EL (electro-luminescence) display, and can output AV
content. Any display is included if it is a display.
[0035]
The “control information acquisition GUI display means” (1015) displays a GUI for control
information acquisition on the display. The “GUI” is a graphical user interface, which uses
graphics as a display of information to the user and performs each operation using the graphics.
Also, since the GUI is for "acquisition of control information", control information can be acquired
through the GUI. For example, when the cursor is placed on the "play" column displayed on the
screen using a remote control device or the like and the execution button is pressed, control
information indicating the "play" is acquired, and the control information is sent to the mobile
audio device. It will be output against. FIG. 11 is a conceptual diagram showing an example of
display of a GUI. A mobile audio setting screen is displayed on the display of the liquid crystal
television, which is an AV device, and the contents related to each operation are displayed on the
display as a GUI. In the example of FIG. 11, the display is shaded to indicate that the item of
"reproduction" is active. In this case, the user presses the execution button in this state when
controlling the "reproduction". On the other hand, when performing "setting" of the mobile audio
device, the active state can be transitioned to "setting" by pressing the ten key indicating "down"
of the remote control device. Here, when the execution button of the remote control device is
pressed, the screen is switched to the setting screen of the mobile audio device, and thereafter
setting of the mobile audio device can be performed similarly using the GUI.
[0036]
By displaying the GUI for acquiring the control information on the display of the AV apparatus in
this way, the control information can be acquired, and therefore, the remote control device
corresponding to the AV apparatus used conventionally is used as it is. It also becomes possible
to control the mobile audio device. That is, various programs and the like for controlling the
mobile audio device are stored inside the AV device, and it becomes possible to use the program
and the like through the GUI, which makes it special to the conventionally used remote control
device. It is possible to control the mobile audio device from the remote control device through
the AV device without preparing settings such as the signal mode. In the present embodiment,
the remote control device has been described as an example of the device that controls the GUI.
However, the present invention is not limited to this. For example, it is possible to operate the
GUI displayed on the screen using the operation button of the AV device body, or by connecting
an input device such as a mouse or keyboard to the AV device An operation may be performed
08-05-2019
13
on the GUI through the input device.
[0037]
FIG. 12 is a diagram illustrating an example of a hardware configuration of a control unit when
displaying a GUI. The control information acquisition GUI display means performs the following
processing. First, the CPU (1201) reads an instruction of the GUI display program stored in the
ROM (1202). Then, based on the instructions of the program, the CPU outputs an instruction for
displaying the GUI on the display to the graphic controller (1204). Then, the graphic controller
(1204) writes the data of the GUI in the graphic memory (1205), and causes the display to
display the GUI based on the data written in the graphic memory. Then, when the user sends a
signal from the remote control device or the like to the AV apparatus while the GUI is displayed
on the display, the signal received by the infrared light receiving unit (not shown) passes through
the I / O (1203). The CPU that has started the GUI display program is notified. Here, for example,
when the signal notified to the CPU is a signal indicating that the cursor movement on the screen
displaying the GUI is performed, an instruction to change and display the GUI is output to the
graphic controller again. Do. On the other hand, when the signal indicates execution for
outputting control information, the CPU reads out the setting information of the GUI stored in the
predetermined area of the RAM (1206), and controls the control information indicated by the
setting information. Give an instruction to output to the mobile audio device through / O.
[0038]
<Flow of Processing of Third Embodiment> FIG. 13 is a diagram showing an example of the flow
of processing of the AV apparatus according to the present embodiment. In step S1301, a GUI for
acquiring control information is displayed on the display. Thereafter, control information of the
mobile audio device is acquired by the GUI. The processes after step S1303 are the same as those
described in the first or second embodiment, and thus the description thereof is omitted here.
[0039]
<Advantage of Embodiment 3> In the mobile audio system in the present embodiment, the AV
device has a display, and a GUI for obtaining control information is displayed on the display to
