The reproduction request acquisition unit 12 acquires a reproduction request from the
smartphone 301. The reproduction request is information for requesting reproduction of audio
data. The reproduction request includes a music title as information for specifying audio data for
which reproduction is requested.
[0027]
The queue management unit 13 manages queue information indicating a queue of a plurality of
reproduction requests. The queue management unit 13 includes a storage unit 14 that stores
queue information for managing queue information.
[0028]
FIG. 4 is a diagram showing an example of the queue information. In the cue information, as
shown in FIG. 4, the music title included in the reproduction request, the setting information, and
the terminal information are associated with each other. The terminal information includes the
network address of each of the smartphones 301, 302, and 303, and the terminal name.
However, the terminal name is information for explanation and is not essential to the queue
information. Further, the terminal information may be, for example, an identification name of the
smartphone as long as it can identify the smartphone that has transmitted the reproduction
request.
[0029]
The queue management unit 13 acquires the music title and the terminal information from the
reproduction request acquisition unit 12, and acquires the setting information from the setting
information acquisition unit 11. The queue management unit 13 updates the queue information
of the storage unit 14 by adding, to the end of the queue information, information in which the
acquired song name, the acquired setting information, and the network address are associated
with each other. When acquiring the music title and not acquiring the setting information, the
queue management unit 13 adds the information in which the music title is associated with the
network address without the setting information to the end of the queue information. The
network address is obtained from communication control information used when the
reproduction request acquisition unit 12 communicates with each of the smartphones 301, 302,
11-04-2019
8
and 303.
[0030]
Returning to FIG. 3, the storage unit 14 stores setting information other than the setting
information included in the queue information. Hereinafter, setting information different from
setting information included in the queue information is referred to as common setting
information (corresponding to second setting information), and each setting information included
in the queue information is referred to as priority setting information. The AV receiver 100
stores the common setting information in the storage unit 14 based on the input of the setting
operation received by the user interface of the AV receiver 100, for example.
[0031]
The queue management unit 13 outputs the music title and the network address to the content
acquisition unit 10. The content acquisition unit 10 acquires audio data indicated by the music
title output from the queue management unit 13 from a terminal corresponding to the network
address. Specifically, the content acquisition unit 10 transmits a reproduction / transmission
instruction to the network address (smartphone 301) associated with the music title by
communication of the wireless LAN standard, and acquires audio data from the network address.
The content acquisition unit 10 outputs the acquired audio data to the reproduction unit 20. The
AV receiver 100 may include a display, and may display music related information (artist name
etc.) included in the additional data of music data acquired from the smartphone 301 on the
display.
[0032]
The queue management unit 13 outputs the setting information of either the common setting
information or the priority setting information to the reproduction unit 20. The reproduction unit
20 reproduces the audio data output from the content acquisition unit 10 in accordance with the
setting information output from the queue management unit 13. Specifically, the reproduction
unit 20 includes an acoustic processing unit 21 and an amplification unit 22. The audio data
output from the content acquisition unit 10 is input to the sound processing unit 21. The sound
processing unit 21 performs various sound processing in accordance with the setting
information output from the queue management unit 13. The audio data after the sound
11-04-2019
9
processing by the sound processing unit 21 is input to the amplification unit 22. The
amplification unit 22 converts the input voice data into an analog signal, and generates an analog
signal for L channel and an analog signal for R channel. The amplification unit 22 adjusts the
level of each generated analog signal in accordance with the setting information output from the
queue management unit 13. The amplification unit 22 outputs the audio signals for the L and R
channels after level adjustment to the speakers 200L and 200R.
[0033]
Next, operations of the AV receiver 100 and the smartphone 301 will be described using FIGS. 5
and 6. 5 and 6 are flowcharts showing the operations of the AV receiver 100 and the smartphone
301, respectively. The flowchart of FIG. 5 shows the operation of adding the music title and the
setting information to the cue information, and the flowchart of FIG. 6 shows the operation of
reproducing audio data based on the cue information.
[0034]
As shown in FIG. 5, the AV receiver 100 and the smartphone 301 negotiate to establish
communication (S0). Negotiation is performed, for example, by the smartphone 301 sending a
connection request to the AV receiver 100 and sending back to the smartphone 301 that the AV
receiver 100 can communicate. Note that the AV receiver 100 acquires the network address of
the smartphone 301 at the time of negotiation.
[0035]
When the negotiation is completed (S0), the smartphone 301 transmits a reproduction request
including the music title to the AV receiver 100 (S1). The reproduction request acquisition unit
12 of the AV receiver 100 receives a reproduction request from the smartphone 301 (S11).
[0036]
When the smartphone 301 transmits the reproduction request (S1), the smartphone 301
transmits the setting information to the AV receiver 100 (S2). The setting information acquisition
11-04-2019
10
unit 11 of the AV receiver 100 receives the setting information from the smartphone 301 (S12).
[0037]
The queue management unit 13 of the AV receiver 100 corresponds the music name included in
the reproduction request acquired in step S11, the setting information acquired in step S12, and
the network address of the smartphone that has transmitted the reproduction request and the
setting information. The attached information is added to the tail end of the queue information
(S13).
[0038]
The AV receiver 100 updates the queue information of the storage unit 14 by performing the
processes of steps S0 to S13 with the respective smartphones 301, 302, and 303.
[0039]
Next, with regard to reproduction of music data based on cue information, as shown in FIG. 6, the
cue management unit 13 determines whether or not audio data is being reproduced by the
reproduction unit 20 (S21).
If the audio data is being reproduced (S21: YES), the queue management unit 13 stands by until
the reproduction of the audio data is completed.
[0040]
When the audio data is not reproduced (S21: NO), the queue management unit 13 determines the
music to be reproduced (S22).
Specifically, the queue management unit 13 takes out the top information (including at least the
music title and the network address) of the queue information. Then, the cue management unit
13 determines the song indicated by the song name included in the extracted information as the
song to be reproduced.
11-04-2019
11
[0041]
When the music piece to be reproduced is determined (S22), the AV receiver 100 transmits a
request to reproduce the sound data of the music piece to the smartphone 301 (S23).
[0042]
When the smartphone 301 receives the request to reproduce the audio data (S31), the
smartphone 301 starts reproducing the audio data corresponding to the music title included in
the request, packetizes the reproduced audio data, and transmits the packet to the content
acquisition unit 10 Send (S32).
[0043]
The content acquisition unit 10 receives an audio data packet from the smartphone 301 (S24).
Audio data is restored from the received audio data packet and output to the reproduction unit
20.
[0044]
When the content acquisition unit 10 receives audio data from the smartphone 301, the queue
management unit 13 determines whether there is priority setting information (S25).
Specifically, when the setting information is included in the information extracted from the queue
information in step S22, it is determined that there is priority setting information corresponding
to the voice data acquired from the smartphone 301 (S25: YES).
[0045]
When the queue management unit 13 determines that there is priority setting information (S25:
YES), the priority setting information is output to the reproduction unit 20, thereby applying the
priority setting to the reproduction unit 20 (S26). If the queue management unit 13 determines
that there is no priority setting information (S25: NO), it applies the common setting read from
11-04-2019
12
the storage unit 14 to the reproduction unit 20 (S27).
[0046]
The reproduction unit 20 reproduces the audio data output from the content acquisition unit 10
according to the priority setting or the common setting (S28).
[0047]
For example, in the example illustrated in FIG. 4, the sound processing unit 21 generates a sound
simulating the reflected sound of the concert hall using the FIR (Finite Impulse Response) filter
for the sound data of the music name 1 designated by the smartphone 301 Do.
The sound processing unit 21 distributes the reflected sound generated by the FIR filter into
sound signals of L and R channels. However, the coefficients (delay amount and level) of the FIR
filter, the distribution ratio of the generated reflected sound to the L and R channels, and the
amplification factor of the amplification unit 22 are included in the setting information output by
the queue management unit 13. The audio signal distributed to each channel is amplified by the
amplifier 22, and then output to the speaker 200L and the speaker 200R. Thereby, the AV
receiver 100 makes the listener feel that the music (music name 1) designated by the user of the
smartphone 301 is played in the concert hall.
[0048]
When the reproduction of the audio data shown in the music name 1 is finished, the AV receiver
100 instructs the smartphone 302 to start reproduction of the audio data of the music name 2
designated by the smartphone 302, and the smartphone 302 starts the reproduction in response
to the instruction. The sound processing unit 21 generates a sound simulating the reflected
sound of the outdoor venue from the received sound data using an FIR filter. Thus, the AV
receiver 100 makes the listener feel that the song designated by the user of the smartphone 302
is played at the outdoor venue. Also in this case, the coefficient of the FIR filter, the distribution
ratio of the reflected sound to the L and R channels, and the amplification factor of the
amplification unit 22 are included in the setting information output from the queue management
unit 13. For example, the FIR filter coefficient of the setting information corresponding to the
music title 2 has a smaller level than the FIR filter corresponding to the music title 1.
11-04-2019
13
[0049]
When the reproduction of the audio data shown in the music name 2 is finished, the AV receiver
100 instructs the smart phone 301 to start the reproduction of the audio data of the music name
3 designated by the smartphone 301, and receives the instruction Thus, the sound processing
unit 21 performs processing to localize the virtual sound source with respect to the received
voice data. For example, the sound processing unit 21 performs convolution processing of an
audio signal based on a head related transfer function. However, the parameters of the head
related transfer function are included in the setting information output from the queue
management unit 13. Thereby, the AV receiver 100 makes the listener feel that the music
designated by the user of the smartphone 301 is emitted also from other than the installation
position of the speakers 200L and 200R.
[0050]
As described above, the AV receiver 100 changes and reproduces the reproduction mode of the
audio data reproduced by each smart phone according to the setting information transmitted
from each smart phone 301, 302, and 303. Therefore, the AV receiver 100 can reproduce the
audio data transmitted from each of the smartphones 301, 302, and 303 in a reproduction mode
corresponding to each user and each device of each of the smartphones 301, 302, and 303.
[0051]
Also, the AV receiver 100 changes the reproduction mode of the content according to the setting
information of each user without changing the common setting information stored in the own
device. Therefore, even if the AV receiver 100 changes the reproduction mode of the content by
each user, each user of each of the smartphones 301, 302, and 303 can be an AV receiver by
maintaining the common setting information stored in the own device. There is no need to
restore the settings after 100 use.
[0052]
In addition, since the AV receiver 100 associates setting information with each piece of music in
11-04-2019
14
the cue information, the reproduction mode can be changed for each piece of music. However, it
is not essential in the present embodiment that setting information is associated with each piece
of music in the cue information. The setting information may be associated with each
smartphone.
[0053]
The setting information may be associated with each user of each of the smartphones 301, 302,
and 303. Furthermore, when the setting information for each user and the setting information
for each music exist, the AV receiver 100 may preferentially use the setting information for each
music. Specifically, when setting information exists for each music, the cue management unit 13
outputs setting information for each music to the reproducing unit 20, and there is no setting
information for each music, and setting information for each smartphone When there is (not
shown), the setting information for each smart phone is output to the reproduction unit 20.
[0054]
In addition, since the AV receiver 100 reproduces the music data according to the common
setting even if the setting information is not transmitted from the smartphone, the music data
can be prevented from being reproduced without any setting.
[0055]
When the content acquisition unit 10 acquires content data including video data, the AV receiver
100 changes, for example, the contrast of the video according to the setting information
according to the user, and the HDMI 4 transmits the content to the external display device.
Output video data after video processing.
Thus, the AV receiver 100 can reproduce the video data in a reproduction mode according to the
user.
[0056]
Further, the AV receiver 100 receives various information by wireless communication of another
11-04-2019
15
wireless standard (for example, Bluetooth (registered trademark) standard) as well as receiving
various information (voice data and setting information) by communication of wireless LAN
standard. You may Furthermore, the AV receiver 100 may receive various information through
wired communication (for example, communication via an HDMI cable connected to the HDMI 4)
as well as wireless communication.
[0057]
Further, the timing of transmission and reception of the setting information is not limited to the
timing shown in FIG. 5 and may be any timing after negotiation and before reproduction of audio
data. Similarly, the timing of transmission and reception of audio data may be any timing after
negotiation and before reproduction of audio data.
[0058]
In addition, if the content reproduction system 900 includes a plurality of AV receivers 100, the
smartphone transmits the same setting information to the plurality of AV receivers 100, for
example, the second reproduction mode in the first AV receiver 100. It can be reproduced in the
AV receiver 100. Thereby, the user of the smartphone can cause the respective AV receivers 100
to reproduce the music data in the same desired reproduction mode regardless of the installation
places of the respective AV receivers 100.
[0059]
Furthermore, when the content reproduction system 900 includes a plurality of AV receivers
100, the following reproduction is also possible.
[0060]
FIG. 7A is a schematic plan view showing the installation of the AV receiver 100A1 at the home
901, and FIG. 7B is a schematic plan view showing the installation of the AV receiver 100A2 at
the place to go out 902.
[0061]
As shown in FIGS. 7A and 7B, the shape of the acoustic space of the home 901 and the place to
go out 902 are different from the connection mode (number and position) of the connected
11-04-2019
16
speakers.
[0062]
In the example shown in FIGS. 7A and 7B, setting information influenced by the shape of the
acoustic space and the connection mode of the speakers is stored in the storage unit 14 of the
AV receivers 100A1 and 100A2, and The setting information which is not influenced by the
shape and the connection mode of the speaker is transmitted from the smartphone 301 to the
AV receivers 100A1 and 100A2.
The other configurations of the AV receiver 100A1 and the AV receiver 100A2 are the same as
the AV receiver 100.
[0063]
For example, the setting information influenced by the shape of the acoustic space and the
connection of the speakers includes the coefficients of the FIR filter, the distribution ratio to each
channel, and the parameters of the head related transfer function.
The setting information which is not influenced by the shape of the acoustic space and the
connection mode of the speaker includes the type of sound field effect, the position of the virtual
sound source, the equalization information, and the volume information.
[0064]
In the example shown in FIG. 7A, the AV receiver 100A1 installed in the home 901 has setting
information corresponding to the shape of the acoustic space of the home 901 and the
connection mode of the speakers 200L and 200R connected to the AV receiver 100A1. That is,
setting information such as the coefficients of the FIR filter and the distribution ratio to each
channel have been stored in the storage unit 14.
Here, when setting information indicating that the type of sound field effect is a concert hall is
11-04-2019
17
transmitted from the smartphone 301 corresponding to certain sound data, the smart phone side
automatically corresponds to the sound data in response to the sound data. Setting information
indicating that the type of is a concert hall is associated and stored on the smartphone side. The
sound processing unit 21 of the AV receiver 100A1 generates a reflected sound to simulate the
sound field of the home 901 as the sound field of the concert hall. Specifically, the sound
processing unit 21 reads from the storage unit 14 setting information such as FIR filter
coefficients corresponding to the type of the sound field effect of the concert hall and the
distribution ratio to each channel, and reads the setting information read out. It is applied to the
reproduction unit 20 to reproduce audio data.
[0065]
In the example shown in FIG. 7B, the AV receiver 100A2 installed at the outing destination 902
has the shape of the acoustic space of the outgoing destination 902, and the speakers 200L,
200R, 200C, 200SL, and 200SR connected to the AV receiver 100A2. Setting information
corresponding to the connection mode, and setting information such as the coefficient of the FIR
filter and the distribution ratio to each channel is stored in the storage unit 14. Here, when
reproduction of audio data is designated by the smartphone 301, as described above, it is set that
the type of the sound field effect that is automatically associated with the audio data and stored
is the concert hall. Information is transmitted from the smartphone 301. Then, the sound
processing unit 21 of the AV receiver 100A2 generates a reflected sound in order to simulate the
sound field of the going destination 902 in the sound field of the concert hall. That is, since the
smartphone 301 transmits the same setting information as the setting information transmitted at
home 901 to the AV receiver 100A2 of the outside 902, the acoustic processing unit 21 of the
AV receiver 100A2 transmits the coefficients of the FIR filter and each channel. The setting
information such as the distribution ratio is read from the storage unit 14, and the read setting
information is applied to the reproduction unit 20 to reproduce audio data.
[0066]
As described above, the smartphone 301 only transmits the same type of sound field effect, and
the sound field according to the shape of the acoustic space and the connection mode of the
speakers for both the AV receiver 100A1 and the AV receiver 100A2 An effect can be imparted
to the sound of the audio data.

Next, a content reproduction system 900B according to the second embodiment will be described
using FIGS. 8 and 9. FIG.
FIG. 8 is a functional block diagram showing a part of the configuration of the content
reproduction system 900B. FIG. 9 is a flowchart showing the operation of the AV receiver 100B
and the smartphones 301 and 302. The flowchart illustrated in FIG. 9 is different from the
flowchart illustrated in FIG. 6 in that the operation of the smartphone 302 is added and the AV
receiver 100B performs the process of step S29.
[0068]
In the content reproduction system 900B, setting information applied to the reproduction unit
20 during reproduction of audio data is transmitted to a smartphone different from the
smartphone that has transmitted the music data.
[0069]
More specifically, as shown in FIG. 8, the content reproduction system 900B is different from the
content reproduction system 900 in that the queue management unit 13B of the AV receiver
100B includes the setting information output unit 15.
Descriptions of configurations overlapping with the content reproduction system 900 will be
omitted.
[0070]
As shown in FIG. 9, when the reproduction unit 20 reproduces audio data (S28) and the
smartphone 302 transmits a request for acquisition of setting information to the AV receiver 100
(S41), the setting information output unit 15 performs the setting information The request for
acquisition of (S29) is received, and the music title corresponding to the audio data being
reproduced by the reproducing unit 20 and the setting information are transmitted to the
smartphone 302 which has made the setting information acquisition request (S30). The
smartphone 302 receives the music title and the setting information from the AV receiver 100B
(S42). That is, the smartphone 302 acquires the music title reproduced by the smartphone 301
and the setting information designated by the smartphone 301 from the AV receiver 100B,

stores the received setting information in the music database of the user in association with the
music title Can be Thereby, the user of the smartphone 302 can obtain the setting desired by the
user of the smartphone 301 together with the music title. For example, the user of the
smartphone 302 causes the AV receiver 100 to reproduce the content to be designated by itself.
At the same time, setting information set by the user of the smartphone 301 can also be applied
to the AV receiver 100.
[0071]
The received setting information may be stored in association with the music title and may be
registered in one of the preset reproduction information, and may be used for reproduction of
other music thereafter.
[0072]
Although the above-mentioned example demonstrated using the AV receiver which outputs an
audio | voice signal to an external speaker as a content reproduction apparatus, a content
reproduction apparatus may be provided with a speaker.
Further, the content reproduction apparatus is not limited to one installed indoors, and may be,
for example, a car audio apparatus installed in a car.
