writable recording medium according to a combination of these may be used.
[0026]
Next, a communication method and a reproduction method of audio data by the audio data
communication system of the present embodiment will be described.
[0027]
First, the viewer X operates the audio data transmitting apparatus 1 in the room A to start
reproduction of a desired music or the like.
09-05-2019
9
At this time, the detection unit 10 in the room A detects the viewer X in the room A and the
information transmission unit 11 transmits the detection information via the power line L. Next,
the control device 12 receives the detection information by the information receiving unit 13 and
outputs a control signal including the speaker ID information of the reproduction speaker device
2 in the room A to the data transmitting unit 6.
[0028]
Further, the data generation unit 5 converts the audio data such as the desired music read from
the storage medium such as a CD into a packet and outputs the packet to the data transmission
unit 6. Thereby, the data transmission unit 6 transmits the packet of the control signal and the
audio data via the power line L. Then, in the reproduction speaker device 2 in the room A, when
the data reception unit 7 receives the packet of the control signal and the audio data, the speaker
ID information received by the audio data reproduction unit 9 matches the speaker ID
information of itself. Recognize that and play back audio data. In the reproduction speaker device
2 in the room B, even if the data reception unit 7 receives the packet of the control signal and the
audio data, the speaker ID information received by the audio data reproduction unit 9 and the
speaker ID information of itself are It recognizes that they do not match and does not play back
audio data.
[0029]
Next, the case where the viewer X moves from the room A to the room B during the reproduction
of the audio data will be described. When the viewer X moves to the room B, the detection unit
10 of the detection device 3 in the room B detects the viewer X in the room B and the
information transmission unit 11 transmits the detection information via the power line L. . Next,
the control device 12 receives new detection information by the information receiving unit 13
and, based on the new detection information, newly generates the control unit 14 including the
speaker ID information of the reproduction speaker device 2 in the room B. The control signal is
output to the data transmission unit 6.
[0030]
The data generation unit 5 continues to output audio data such as the desired music as a packet
to the data transmission unit 6, but the data transmission unit 6 includes the new control signal
09-05-2019
10
and transmits the audio data packet through the power line L. To send. Then, in the reproduction
speaker apparatus 2 in the room B, when the data receiving unit 7 receives a new control signal
and a packet of audio data, the speaker ID information received by the audio data reproducing
unit 9 and the speaker ID information of itself are one. It recognizes that it does, and plays back
and outputs audio data. In the reproduction speaker device 2 in the room A, the data reception
unit 7 receives a new control signal, and the speaker ID information received by the audio data
reproduction unit 9 does not match the speaker ID information of itself. In order to recognize,
stop the reproduction output of audio data.
[0031]
As described above, in the present embodiment, the detection device 3 detects the viewer X in
the room A or B, and the control device 12 is a detection device among the reproduction speaker
devices 2 installed in the room A and the room B, respectively. Since 3 reproduces audio data by
controlling the reproduction speaker apparatus 2 in the room where the viewer X is detected and
reproduces the audio data only by the reproduction speaker apparatus 2, reproduction of the
audio data is performed only in the movement destination room where the observer X exists. It
can be done efficiently. Therefore, even if the viewer X does not move by carrying the audio data
transmitting apparatus 1, audio reproduction can be continuously viewed in the destination room
B. In addition, since the system is constructed via the power line L, there is an advantage that no
facility cost for adding a communication line and no construction cost are required.
[0032]
Next, an audio-visual data communication system, an audio-visual data communication method,
and an audio-visual data communication program according to a second embodiment of the
present invention will be described with reference to FIG. In the following description of each
embodiment, the same components as those described in the above embodiment are denoted by
the same reference numerals, and the description thereof will be omitted.
[0033]
The difference between the second embodiment and the first embodiment is that in the first
embodiment, the detection device 3 detects only the presence or absence of the viewer X in the
room A or B to transmit detection information. In the second embodiment, as shown in FIG. 3, the
detection device 21 includes an authentication unit 24 that identifies not only the presence of
viewers but also a plurality of viewers X and Y for each viewer X and Y, The point is that the
09-05-2019
11
control device 12 controls the reproduction speaker device 2 corresponding to the identified
viewers X and Y.
[0034]
That is, in the second embodiment, an RF-ID (Radio Frequency Identification) card, which is a
non-contact IC card in which the authentication means 24 of the detection device 21 is portable
and can transmit identification information wirelessly by the viewers X and Y. Wireless
communication unit (wireless communication) capable of wirelessly receiving the identification
information between the contactless identification devices 22x and 22y and the RF-ID cards 22x
and 22y provided in each of the rooms A and B and in the rooms A and B Means 23).
Each of the RF-ID cards 22x and 22y has identification information of the corresponding viewers
X and Y, and performs data communication of the identification information with the wireless
communication unit 23 by electromagnetic induction.
[0035]
The detection device 21 further includes an information transmission unit 11 that transmits the
identification information received by the wireless communication unit 23 through the power
line L. Furthermore, the control device 12 according to the second embodiment is also set to
select the audio data to be reproduced from the reproduction speaker device 2 based on the
preset priorities for the viewers X and Y. It differs from the embodiment.
[0036]
A communication method and a reproduction method of audio data by the audio data
communication system in the second embodiment will be described.
[0037]
For example, when the viewer X is a father and the viewer Y is a child, both of them select
different tunes to play audio data of different songs, and only the viewer X of the father has a
room. If it moves to B, the detection device 21 in the room B detects the RF-ID card 22x of the
09-05-2019
12
viewer X by the wireless communication unit 23 and receives the identification information of
the RF-ID card 22x by wireless.
Then, the information transmission unit 11 transmits the identification information via the power
line L.
[0038]
Furthermore, the control unit 14 of the control device recognizes that the viewer X of the father
is present in the room B based on the identification information received by the information
reception unit 13, and the audio data selected by the viewer X is used as a playback speaker in
the room B It transmits including the speaker ID information of the device 2. In the reproduction
speaker apparatus 2 in the room B, the data receiving unit 7 receives audio data including the
speaker ID information through the power line L and the audio data reproducing unit 9 matches
the speaker ID information with the speaker ID information of itself. Check and play back audio
data. In the reproduction speaker apparatus 2 of the room A, reproduction and output of the
audio data selected by the viewer X are not performed because the speaker ID information of the
room A does not match the received speaker ID information.
[0039]
Further, as shown in FIG. 3, assuming that both the father's viewer X and the child's viewer Y
move to the room B, the wireless communication unit 23 in the detection apparatus 21 in the
room B is the viewer X, Y , And wirelessly receive their identification information. Then, the
information transmission unit 11 transmits the respective identification information via the
power line L. Further, the control unit 14 of the control device recognizes from the identification
information received by the information receiving unit 13 that the viewer X of the father and the
viewer Y of the child exist in the room B. On the other hand, the audio data to be reproduced is
selected from the reproduction speaker device 2 based on the preset priority, and the audio data
to be reproduced is output to the data generation unit 5.
[0040]
That is, by setting the priority of the father's viewer X higher than that of the child's viewer Y, the
09-05-2019
13
control unit 14 determines that the father's viewer X is more than the music selected by the
child's viewer Y. The audio data of the selected music piece is preferentially selected and output
to the data generation unit 5 as audio data to be reproduced. Thus, the data generation unit 5
converts the audio data of the music output by the control unit 14 and selected by the father's
viewer X into a packet, and the data transmission unit 6 transmits the packet via the power line
L. Next, the reproduction speaker device 2 in the room B receives the control signal and the
audio data of the music selected by the father's viewer X by the data receiving unit 7 and
reproduces and outputs the audio data from the audio data reproduction unit 9.
[0041]
As described above, in the present embodiment, since the control device 12 controls the
reproduction speaker device 2 corresponding to the viewers X and Y identified by the
authentication unit 24, even when there are a plurality of viewers X and Y, identification is
performed The viewer X can be recognized and the reproduction of the audio data selected by
the viewer X can be performed at the destination. In addition, since the control device 12
controls the reproduction speaker device 2 based on the priorities of the viewers X and Y, the
viewers X and Y recognized when the viewers X and Y simultaneously move to the same room B
or the like. It is possible to preferentially reproduce the audio data selected by the viewer X
having a high priority among Y at the moving destination.
[0042]
Furthermore, since the wireless communication unit 11 receives the identification information of
the viewers X and Y in the rooms A and B by wireless communication with the RF-ID cards 22x
and 22y, the viewer X or Y moves to the room A or the destination room Once in B, it is possible
to automatically recognize the viewers X and Y, and it is possible to save the viewers X and Y
from performing the authentication work.
[0043]
Next, the third embodiment and the fourth embodiment of the audio visual data communication
system, the audio visual data communication method, and the audio visual data communication
program according to the present invention will be described.
[0044]
The difference between the third embodiment and the second embodiment is that, in the second
embodiment, the authentication means 24 having the RF-ID cards 22x and 22y and the wireless
09-05-2019
14
communication unit 23 is employed, while the third embodiment is employed. In this
embodiment, biometrics means for identifying the viewers X and Y based on the physical
features of the viewers X and Y is adopted as the authentication means.
[0045]
For example, as the biometric authentication means, fingerprint authentication is performed by
scanning the fingertips of the viewers X and Y to read fingerprints for identification, iris
authentication to scan the patterns of black eyes of the viewers X and Y, and identification is
performed, Voiceprint authentication that analyzes and identifies the voices of the viewers X and
Y, face recognition that shoots and identifies face shapes of the viewers X and Y, and veins in the
palm of the viewers X and Y using infrared rays An authentication device such as vein
authentication that performs scanning and reading identification is employed.
Therefore, since the authentication means is a biometric authentication means for identifying the
viewers X and Y based on the physical features of the viewers X and Y, the viewers X and Y
themselves are the RF-ID cards 22x and 22y for authentication. It is possible to play audio data
on the move destination without wearing an etc.
[0046]
The fourth embodiment differs from the second embodiment in the fourth embodiment while the
detection device 21 includes the information transmission unit 11 and the wireless
communication unit 23 connected by wire. In the embodiment, as shown in FIG. 4, the detection
device 121 detects each of the RF-ID cards 22x and 22y of the viewers X and Y, receives each
identification information by radio, and transmits the identification information by radio. In that
it comprises a wireless sensor (wireless communication means) 123 which is a wireless
communication unit, and a wireless PLC bridge 111 which is an information transmission unit for
transmitting the received identification information to the control device 12 as a server via the
power line L. It is different.
[0047]
That is, in the fourth embodiment, by connecting the wireless sensor 123 and the wireless PLC
bridge 111 by wireless communication, the detection system can be configured without wiring,
and the tracking system can be easily installed. .
09-05-2019
15
In addition, since the wireless sensor 123 has a high degree of freedom in installation and there
are few restrictions on the installation location, it is possible to improve detection accuracy and
diversity of the RF-ID cards 22x and 22y.
[0048]
The technical scope of the present invention is not limited to the above embodiment, and various
modifications can be made without departing from the scope of the present invention.
[0049]
In each of the above embodiments, the case of transmitting and receiving audio data via the
power line L has been described. However, not only audio data but also visual data may be
transmitted and received via the power line L.
In this case, a visual data reproduction apparatus such as a DVD player is employed instead of
the audio data transmission apparatus 1, and a reproduction apparatus such as a liquid crystal
display apparatus is employed instead of the reproduction speaker apparatus 2.
[0050]
In each of the above embodiments, the detection devices 3 and 21 are installed on the walls W of
the rooms A and B, but the reproduction speaker devices 2 of the rooms A and B may have the
detection devices incorporated therein.
Furthermore, although the control device 12 is provided in the audio data transmission device 1,
the control device 12 may be connected to the power line L independently of the audio data
transmission device 1.
Moreover, in 2nd Embodiment, although RF-ID card 22x, 22y is used as a non-contact
identification apparatus, you may employ | adopt an RF-ID tag as another non-contact
identification apparatus.
