[0039]
Subsequently, each functional block constituting the control application 270 will be described.
Note that each functional block of the control application 270 may have the same function as
each functional block of the control application 170 of the wireless communication device 100.
That is, the operation control unit 276 corresponds to the operation control unit 176, the
wireless communication control unit 271 to the wireless communication control unit 172, the
battery information acquisition unit 274 to the battery information acquisition unit 174, and the
notification control unit 275 to the notification control unit 175. Since the functional blocks are
01-05-2019
12
similar to one another and each have similar functions, the functional blocks having different
functions from the control application 170 will be mainly described here.
[0040]
The wireless communication control unit 271 controls the wireless communication unit 210 to
receive streaming data transmitted from an external device and transmit / receive various
requests and the like. The reproduction control unit 272 reproduces the streaming data received
by the wireless communication unit 210. Here, the reproduction process is a process of decoding

[0041]
Similar to the battery information acquisition unit 174, the battery information acquisition unit
274 can acquire battery information (information regarding the remaining amount of battery)
regarding the battery 240 of the speaker device 200 and the battery 140 of the wireless
communication device 100. Then, when acquiring the battery information of the battery 240, the
battery information acquisition unit 274 instructs the wireless communication control unit 271
to transmit the battery information request to the wireless communication device 100, and from
the wireless communication device 100 as a response to the battery information request. The
battery information transmitted and received by the wireless communication unit 210 is
acquired. The battery information acquisition unit 274 can also request the wireless
communication device 100 to transmit a battery information notification so that the wireless
communication device 100 voluntarily transmits a notification including battery information.
[0042]
The content information acquisition unit 273 requests the wireless communication device 100
for reproduction time length information for requesting reproduction time length information on
the length of the content corresponding to streaming data currently being reproduced, and
streaming data currently being reproduced. By causing the wireless communication unit 210 to
transmit the reproduction position information request for requesting the current reproduction

[0043]
01-05-2019
13
The content information acquisition unit 273 can also request the wireless communication device
100 to notify the wireless communication device 100 of the reproduction position notification
information so that the wireless communication device 100 voluntarily transmits the
reproduction position information.
For example, the wireless communication device 100 causes the wireless communication device
100 to transmit, from the wireless communication control unit 271 to the wireless
communication device 100, a reproduction position information notification request in which the
content information acquisition unit 273 specifies EVENT̲PLAYBACK̲POS̲CHANGED in

device 200 is notified of the reproduction position information of the wireless communication
device 100.
[0044]
Although the wireless communication device 100 that is the external device of the
communication partner of the speaker device 200 can not necessarily notify the battery
information voluntarily, the speaker device 200 notifies the external device of the
communication partner of the reproduction position information By transmitting the availability
response request, it can be determined whether or not the external device can transmit the
reproduction position information voluntarily.
[0045]
Here, the content information acquisition unit 273 transmits, to an external device, a playback
position information notification availability request with EVENTS̲SUPPORTED specified in
GetCapabilities of the VENDER DEPENCENT command in AVRCP of Bluetooth, for example, and
EVENT̲PLAYBACK̲POS̲CHANGED is included in the response. Whether or not the wireless
communication device 100 can transmit the reproduction position spontaneously can be
determined.
More specifically, if EVENT̲PLAYBACK̲POS̲CHANGED is included in the response from the
external device to the reproduction position information notification availability request
transmitted by the speaker device 200, the wireless communication device 100 spontaneously
transmits the reproduction position information. It can be determined that the reproduction

14
position information can not be transmitted spontaneously unless
EVENT̲PLAYBACK̲POS̲CHANGED is included.
[0046]
The battery information acquisition unit 274 can acquire battery information (information on the
remaining amount of battery) regarding the battery 240 of the speaker device 200 and the
battery 140 of the wireless communication device 100. In addition, since the battery information
acquisition unit 274 has the same function as the battery information acquisition unit 174 of the
wireless communication device 100, the detailed description will be omitted.
[0047]
When the notification control unit 275 receives a low battery notification instruction from the
operation control unit 276, the notification control unit 275 performs low battery notification.

reproduction time length information indicating the length of the content corresponding to the
streaming data, and based on these information The time when the reproduction position of the
streaming data reaches the end of the streaming data, that is, the wireless communication unit
210 receives the streaming data for the audio data of 1, and the reproduction control unit 272
calculates the scheduled end time to complete the reproduction. . Then, based on the battery
information acquired by the battery information acquisition unit 274 and the scheduled
reproduction end time of the streaming data being reproduced, the operation control unit 276
determines the remaining of the battery of at least one of the speaker device 200 and the
wireless communication device 100. When the amount becomes equal to or less than a
predetermined value and the streaming is completed, the notification control unit 275 is notified
of the battery remaining amount decrease notification.

device 100 receives a response indicating that battery information notification to the request is
possible (Yes in S303), the battery information acquisition unit 174 transmits a battery
information notification request to the speaker device 200 (S304). On the other hand, when the
speaker device 200 can not transmit the battery information notification (No in S303), the
operation control unit 176 sets the battery information acquisition unit 174 to periodically
transmit the battery information request to the speaker device 200 (S305) .
[0050]
Subsequently, the wireless communication device 100 starts transmission of streaming data to
the speaker device 200 (S306). Next, the battery information acquisition unit 174 determines
whether or not the battery information request is set to be periodically transmitted (S307). When
the setting in S305 is made (Yes in S307), the battery information acquisition unit 174
determines whether it is the time to transmit the battery information request (S308).
[0051]
If it is time to transmit the battery information request (Yes in S308), the battery information
acquisition unit 174 instructs the wireless communication control unit 172 to transmit the
battery information request to the speaker device 200. When the battery information acquisition
unit 174 acquires the battery information received from the speaker device 200 in response to
the request (S309), the battery information acquisition unit 174 subsequently acquires the
battery information of the own device (S310).
[0052]
01-05-2019
16
Then, based on the acquired battery information, the operation control unit 176 determines
whether the remaining battery level of at least one of the wireless communication device 100
and the speaker device 200 is equal to or less than a predetermined value (S311). When the
battery remaining amount is equal to or less than the predetermined value (Yes in S311), the
operation control unit 176 sets a flag indicating that the battery remaining amount is insufficient
(S312), and the reproduction time length information of the content information acquisition unit
173 Whether or not the streaming data being transmitted by the wireless communication unit
110 has reached the end is determined based on the reproduction position information and the
reproduction position information (S313). When the end is reached (Yes in S313), the operation
control unit 176 performs the process of S319.
[0053]
If it is not time to transmit the battery information request in S308 (No in S308), the wireless
communication device 100 determines whether the data being streamed has reached the end
(S314). When the end has been reached (Yes in S314), the wireless communication device 100
performs the process of S319, and when the end has not been reached (No in S314), the wireless
communication device 100 performs the process of S308 again.

communication device 100 and the speaker device 200 based on the battery information
acquired by the battery information acquisition unit 174 and the reproduction time length
information acquired by the content information acquisition unit 173. It is determined whether
the remaining amount satisfies the battery remaining amount necessary to complete
transmission of streaming data to be transmitted next (S407).
[0061]
Then, when the battery remaining amount of each of the wireless communication device 100 and
the speaker device 200 is equal to or more than the required battery remaining amount (No in
S407), the wireless communication device 100 starts transmitting the next streaming data
(S401), When it is less than the required battery remaining amount (No in S407), the processing
of S408 to S410 is performed.
In addition, since the process of S408-S410 is the same as the process of S320-S322 in FIG. 3,
