[0038]
6 and 7 show an example of a table for managing the audio system 10. As shown in FIG. FIG. 6 is
a system management table for managing the connection form of each audio device 4 in the
network 9. FIG. 7 is an audio control table that manages the arrangement and operation of each
audio device 4 that configures the audio system 10. The system management table is mainly
used to manage the network connection by the audio device 4-1 which is the root device. Also,
the audio control table is mainly used by the controller 1 for reproduction control of the audio
source. The audio device 4-1, which is a multi-zone device, is treated as one device in the system
management table, and managed in each zone (unit) in the audio control table.
[0039]
The system management table of FIG. 6 stores the connection form of each audio device 4
constituting the audio system 10, and is created by the controller 1 when the audio system 10 is
constructed. Also, when a new audio device 4 is added to the audio system 10, the controller 1
performs updating to add the audio device 4 to the system management table. The system
management table created or additionally updated is transmitted from the controller 1 to the
root device 4-1.
[0040]
The system management table is identified by a system ID for identifying the audio system 10.
Each audio device 4 is associated with the device ID of each device, and the MAC address of the
upper side (child device side) / lower side (internal access point side) (that is, the MAC address of
the wireless LAN communication unit 56/57), the upper side IP address on the side / lower side
(that is, the IP address of the wireless LAN communication unit 56/57), number of connection
stages (HOP number) from the root device 4-1, presence or absence of activation of internal
access point, connection to internal access point 4A It stores information such as the number of
subordinate devices (the number of Child). In the system management table of FIG. 6, the multizone device 4-1 which is the root device is a device of device ID = 00, and is registered as one
audio device regardless of the number of built-in units. Then, communication with all units is
performed with the same IP address (via the same wireless LAN communication unit 56 or 57 or
the wired LAN communication unit 58).
09-05-2019
12
[0041]
Each audio device 4 has an individual IP address, but the audio system 10 has a multicast
address set as a multicast group. By transmitting the IP packet of the above system information
to the multicast address, it is possible to make all the audio devices 4 of the audio system 10
receive this system information packet. Although the system information packet may be
transmitted by unicast to the IP address of each audio device 4, the load of the network 9 can be
reduced by transmitting by multicast.
[0042]
The audio control table of FIG. 7 is associated with the device ID and zone number of each device,
and the upper side IP address (IP address of the wireless LAN communication unit 56) of each
audio device, model, installation location (room), group, It stores various setting information such
as service, volume value and display name. Each field of the audio control table and each field of
the system management table are associated with each other by a device ID. In the case of the
multi-zone device 4-1, one audio device has a plurality of audio units, and each audio unit can be
assigned to a separate room. The controller 1 creates the control screens of FIGS. 16 and 17
based on the contents of the audio control table, and receives an operation by the user.
[0043]
The installation location is information identifying a room in which the audio device is installed.
Although the room name is displayed on the table in FIG. 7, the information on the installation
location may be, for example, the room ID of the installed room.
[0044]
A group is information on a group to which each audio device or audio unit belongs, and
indicates a group for performing synchronized reproduction of the content described above. Note
that group setting by the user is not performed by directly specifying an audio device or an audio
unit, but indirectly specifying an audio device or an audio unit installed in the room by specifying
a room. Be done. A group consists of one master that delivers audio source content (audio
signals) to each audio device in the group, an audio unit, and one or more clients that receive
09-05-2019
13
audio signals from the master and emit them into the room Become.
[0045]
The master is in charge of supplying an audio source to the entire group and controlling
synchronous reproduction, and also functions as one device of synchronous reproduction. The
client treats the master as an audio source, receives an audio signal from the master, processes
the audio signal in the audio processing unit, and emits the sound. In the "group" item of the
audio control table, the number of the group to which it belongs and the type of master (M) /
client (C) are stored. For example, “1M” stored in the unit ID = 1 column of the device ID = 00
(audio device 4-1) in the same figure indicates that it is the master of the group with the group
number 1.
[0046]
The service is information indicating an audio source that each audio device 4 can reproduce. As
shown in FIGS. 3 and 4, the audio device 4-1 with device ID = 00 can play DVD and Radio
(including FM broadcast and net radio) and various network contents, and the device ID = 01,
The audio devices 4-2 and 3 of 02 can play Radio and various network contents. Although not
described in the service item of the audio control table, each audio device (audio unit) receives an
audio signal from another audio device (other audio unit) when it becomes a group playback
client. That is, the other audio device (other audio unit) is used as an audio source (service) to
play back (discharge) the audio signal. When two audio devices 4 become masters and clients,
these audio devices 4 transmit and receive audio signals via the network 9. When the first unit
61 of the multi-zone device 4-1 is a master and the second unit 62 is a client, the second unit 62
inputs an audio signal of the first unit 61 in a connection form called a main zone sink.
[0047]
Hereinafter, reproduction of content by a group including the multi-zone device 4-1 will be
described. First, FIG. 8 is a diagram showing the form of reproduction by a general group.
Although only one client is shown for ease of explanation, the number is not limited. The master
reproduces a predetermined (user-selected) audio source (content of the audio source), emits the
reproduced audio signal by itself, and transmits it to the client via the network 9. The client emits
an audio signal received from the master. Next, FIG. 9 is a diagram for explaining the function of
09-05-2019
14
the assigner 67 of the multi-zone device 4-1 shown in FIG. 4. To the assigner 67, the outputs of
the plurality of audio sources 63 and 64, the network 9 and the audio circuit 53 of the first unit
61 are connected as inputs. Further, to the assigner 67, a first unit (Unit 1) 61, a second unit
(Unit 2) 62, and the network 9 are connected as outputs. The assigner 67 assigns an input to an
output according to an instruction of the control unit 50 based on a command of the controller 1.
[0048]
FIG. 10 shows a mode of group reproduction when the first unit 61 (main zone) of the multi-zone
device 4-1 is the master and the other audio device 4 is the client. A predetermined (user
selected) audio source (e.g., DVD 64) is connected to the first unit 61, and the first unit 61
reproduces and emits the sound, and the reproduced audio signal is assigned to the assigner 67.
Enter in The assigner 67 transmits the reproduced audio signal to the client 4 via the network 9.
The client 4 emits this audio signal. The first unit 61 delays the audio signal for a predetermined
time and then emits the sound in order to synchronize the reproduction timing with the client 4
that receives the audio signal via the network 9. The assigner 67 may directly connect the audio
source connected to the first unit 61 to the network 9 to transmit the reproduction signal to the
client (see dotted line). Since the second unit 62 is not selected as a client, it does not play back
the audio source. In addition, when it is functioning as a surround speaker of the 1st unit 61
(main zone), the audio | voice of saran udback LR can also be output.
