amplifier device 301 are connected to the second recorder device (recorder device 2) 501
(physical address [1. 2.0.0] and the television apparatus 101 or the AV amplifier apparatus 301
are connected by the fifth HDMI cable 15, respectively. It goes without saying that the physical
address corresponds to the address of each target device on the HDMI connection.
[0021]
The connection example shown in FIG. 1 is different from the connection shown in FIGS. 2 and 3
in addition to the HDMI cable 11 (first connection) connecting the recorder device 201 and the
television device 101, and the recorder device 201 and A second connection by the HDMI cable
13 connecting the AV amplifier device 301 is included. Note that the second connection is an
image and an audio signal (the example in FIG. 1 is an audio signal because it is a connection
with an AV amplifier device) independently of the first connection that connects the recorder
device 201 and the television device 101. Can be transmitted.
[0022]
That is, in the current HDMI standard, when an ARC (Audio Return Channel) line is detected in
the CEC (Consumer Electronics Control) line standard, an audio signal is specified via the ARC (by
the reproduction capability of the television apparatus) Audio signal). Therefore, even when the
quality of the audio signal that can be reproduced by the AV amplifier device 301 is higher than
the quality of the audio signal that can be reproduced by the television device 101, the audio
signal reproduced by the AV amplifier device 301 passes through the ARC line It becomes the
quality reproduced on the 101 side.
[0023]
That is, in the connection shown in FIG. 1, input of selection and determination of input switching
display in UI (User Interface) display displayed on the screen of the television apparatus 101 (by
a user) or input of a remote control (remote controller) terminal When the recorder device 201
connected by the HDMI cable 12 is selected as a device to be viewed (content supply source) by
the operation of the switching key, TV → [Broadcast] <Routing Change> [*. *. *. *]
([*. *. *. *] Indicates that the physical address not specifying a specific device is
supplied (sent) to the CEC line, and the television apparatus 101 stores in advance according to

TV → [Broadcast] <Set Stream Path> [2.0.0.0] From the connected device list being selected (in
FIG. 1, the physical address [2.0.0.0] is given) the recorder device 201 is selected.
[0024]
The selected recorder device 201 (in fact, the device specified by the physical address [2.0.0.0]
among the devices connected by HDMI) is: Recorder → [Broadcast] <Active Source> [2.0 .0.0] will
be returned.
[0025]
Note that, according to the HDMI standard, in the recorder device 201 that is a source device
according to the HDMI standard, when the power of the device is turned on, the television device
101 that is a sink device normally The physical address (of the television apparatus 101)
recorded in the) EDID (Extended Display Identification Data) is read, and the input interlock is
notified to the CEC line by the <Report Physical Address> command.
[0026]
As a result, the AV amplifier device 301 that has received the command also changes its own AV
selector according to the physical address of the parameter (in the connection of FIG. 1, the
HDMI cable 12 connected to the television device 101 for the video signal). And select the
corresponding HDMI port, and for an audio signal, select the HDMI cable 13 connected to the
recorder apparatus 201 and the corresponding port).

[0028]
In detail, the HDMI cable 12 is input by selecting and determining an input switching display in
UI (User Interface) display displayed on the screen of the television apparatus 101 (by a user) or
by operating an input switching key of the remote control terminal. When the recorder apparatus
201 connected to the television apparatus 101 is selected as a device to be viewed (content
supply source) by the user, the television apparatus 101 causes the recorder apparatus 201 to
execute <Routing Change> [*.
*.
*. * [Broadcast] [011].
[0029]
Similarly, the television apparatus 101 sends an AV (audio) amplifier 301 <Routing Change> [*.
*. *. * [Broadcast] [021].
[0030]
Note that “<Routing Change> [*. *] Shown in [011] and [021] described above in FIG. *. *.
*]] Is a broadcast (simultaneous transmission) (FIG. 4 is divided and described for each
transmission destination for convenience, and does not have a time series as shown).
[0031]
Also, the television apparatus 101 [Broadcast] <Set Stream Path> [2.0.0.0] in the recorder
apparatus 201 [012].
[0032]
09-05-2019

The recorder apparatus 201 [Broadcast] <Active Source> [2.0.0.0] to the television apparatus
101 and the AV amplifier apparatus 301 [031] and [032].
Note that “<Routing Change> [*. *] Described in [011] and [021] described above. *. *. * "]
And" [Broadcast] [Active Source] [2.0.0.0] "shown in [031] are shown separately for each
transmission destination for convenience, as shown in the figure. Not be accompanied by a time
series).
[0033]
Also, the television apparatus 101 transmits <User Control Pressed> [Select A / V Input Function]
to the AV amplifier apparatus 301 [022].
[0034]
As for the audio input terminal of the AV amplifier device 301, in the "switch to input" X
"attached to" <User Control Pressed> [Select A / V Input Function] ", the number that enters" X "is
used as a parameter The HDMI-CEC command of “[Select A / V Input Function] [X]” is issued
to the AV amplifier device 301.
[0035]
At this time, the first data of the physical address added to the HDMI-CEC command “switch to
input“ X ”” (in this example, with physical address [2.0.0.0] of the recorder apparatus 201 to
“2” On the basis of (1), the number of the HDMI port (for example, displayed by any of 4 bits
“0x00 to 0xFF”) of the television apparatus 101 to which a newly viewed device (content
supply source) is connected is determined.
[0036]
Specifically, the input association database held by the television apparatus 101, an example of
which is shown in the latter part of FIG. 5, is acquired, and the input association is performed
based on the HDMI input terminal (HDMI port number) of the television apparatus 101
determined from the physical address. The input terminal (HDMI port number) of the AV
amplifier apparatus 301 is acquired from the database.
[0037]
09-05-2019
10
As a result, the ARC (automatic selection of the path of the audio signal according to the CEC
standard) of the HDMI cable (the cable 12 in the example of FIG. 1) connecting the AV amplifier
device 301 and the television device 101 can be cancelled.
That is, in the example shown in FIG. 5, when the input of the television apparatus 101 is
switched to HDMI 2 by setting the item of HDMI 2 to “Input 2”, the input of the AV amplifier
301 is also switched to “Input 2”. Video / audio (audio) is output along a path expected by the
user (audio is reproduction processing by the recorder device 201 different from reproduction
processing by the television device 101).
The changed setting (input association database) is stored in a predetermined storage area in
which data is held even when the main power is turned off, such as NVRAM (nonvolatile
memory).
FIG. 6 shows an example of the combination of the changed HDMI port (the physical address of
the device which inputs the audio signal and the physical address of the device which inputs the
video signal).
[0038]
Further, the notations such as “input 1”, “input 2” and the like in FIG. 5 only indicate
identification when there are a plurality of HDMI ports, and are actual port numbers or
connection names displayed on the television set 101 It is different.
The notation can use any form as long as identification of the port (and cable to be connected /
configured signal path) is possible.
[0039]
FIG. 7 shows another example of the input association database held by the television device.
[0040]
In FIG. 7, in the portion (port) indicated as “auto”, the input switching cooperative operation
(port assignment) of the AV amplifier device 301 is not changed, that is, the input switching
09-05-2019
11
predetermined in the AV amplifier device 301 Indicates that the operation is as per the
specification.
[0041]
In detail, when the value (port) other than "auto" is set in the input switching of the AV amplifier
device 301 and the input of the television device 101 is switched to the input (port), the input of
the AV amplifier device 301 is designated Is switched to the selected input.
On the other hand, if the input of the television apparatus 101 is switched to the input of the AV
amplifier apparatus 301 (“HDMI 1” in the connection example of FIG. 7) at any timing,
“<Routing Change> [*.
*. *. Since *]] is effective, it will be in the state which selected input 2 switched forcibly.
That is, “<Routing Change> [*. *. *. As the command *]] includes a rule for finally
switching the AV amplifier apparatus (to the last), as described above, the input switching is
fixed. It should be noted that (1) input switching is not performed, and a viewing device is
directly selected by device selection, or (2) external input setting of an input (port) connected to
the AV amplifier device 301 (in the example of FIG. 7) , HDMI 1) set to other than auto (for
example, set to “input 1” and switch to the player device 401 (physical address [1.1.0.0])) to
switch the input as described above Can be prevented from being fixed.
[0042]
FIG. 8 shows the change of the input switching cooperation operation (allocation of the HDMI
port) described in FIG. 4 and FIG. 5 (or FIG. 7) in terms of software.
[0043]
First, a change in the physical address (video / audio supply source (viewing target device)) of a
device connected by HDMI is detected [11].
[0044]
The HDMI input terminal of the television apparatus is determined based on the new physical
address that detected the change [12].
09-05-2019
12
[0045]
The input association database is obtained from the input association database (referring to the
input association database) [13].
[0046]
Thereafter, it is determined whether or not switching of the input terminal of the AV amplifier
apparatus is instructed in the acquired input association database (input switching is not set /
"auto" is set) [14], and switching is instructed. If (Yes) [14-YES], according to the input
association database, CEC command corresponding to the switching of the input terminal of the
AV amplifier device <User Control Pressed> [2.0.0.0] [ Send [Select A / V Input Function] [X]]
[15].
[0047]
On the other hand, when the switching is not instructed ("auto" is set) [14-NO], the HDMI
connection to the input terminal of the AV amplifier apparatus is maintained as it is.
[0048]
Moreover, although the above-mentioned CEC command can be used only within the same
vendor, it may be prepared as a vendor command (Vendor Specific Commands) defined in the
HDMI-CEC standard.
[0049]
In addition, the change of the input switching cooperation operation (allocation of the HDMI
port) described with reference to FIGS. 4 to 8 is applied (changed / not changed) by the UI
display using the setting screen whose example is shown in FIGS. 9A and 9B. Can be set
arbitrarily.
In the state where the screen display 111 is displayed, when change of input switching
cooperation operation (allocation of HDMI port) is instructed by input of selection and
determination of input switching display or operation of input switching key of remote control
terminal, as shown in FIG. As 9A shows, the connection change menu 116 for changing the
connection of the source of the viewing target displayed by the screen display 111, that is, the
viewing target device is displayed.
09-05-2019
13
When the television apparatus 101 (and the recorder apparatus 201) is compatible with digital
terrestrial broadcasting, the screen display 111 is the "blue" button 112, the "red" button 113,
the "green" button 114, "yellow" on the remote control terminal. It is also possible to accept an
instruction corresponding to the four buttons 115, and give a dedicated process name for
changing the above input switching cooperation operation (allocation of the HDMI port) as an
instruction corresponding to any of the buttons. it can.
[0050]
The connection change menu 116 is, for example, the first to fifth HDMI connections 121 to 125
and other connections (exemplary videos 1 to 3) 126 to 129 and a broadcast station that is a
supply source of content (program) currently being viewed. CH (channel) name 121 is included.
Note that [HDMI] 2 display 123 in connection change menu 116 display informs that it is the
source of the view target (content / program / title (program)), that is, the target of the
connection change menu for changing the connection of the view target device. [Model change
target for connection change] 123a is included.
[0051]
When [Connection change target model display] 123a is selected by, for example, cursor
movement and focus (decision input) by operation of the remote control terminal, as shown in
FIG. 9B, the connection change target device list 117 is displayed on the screen display 111. Is
displayed.
In the example shown in FIG. 9B, the recorder 1 corresponds to the recorder device (2) 501 (in
the system of FIG. 1) which has already been confirmed in the television device 101 that the
HDMI connection is made as the connection change target device. The display 131, the recorder
2 display 132 corresponding to the (same) recorder device 201, the amplifier display 133
corresponding to the AV amplifier device 301, and the like are displayed.
[0052]
09-05-2019
14
Hereinafter, for example, when the recorder 2 display 132 corresponding to the recorder device
201 is selected by, for example, cursor movement and focus (determination input) by operation
of the remote control terminal, it is exemplified by FIG. ) Whether there is a connection change
(AV system external input setting) in the device (viewing device) connected by each HDMI port
and HDMI cable (if the connection change is set, the connection destination (switched input
terminal) First name is displayed.
[0053]
When there is no [connection change target model] (the recorder apparatus 201 shown in FIG. 1
does not have two or more HDMI ports), the television apparatus 101 receives a user instruction
/ input by the operation of the remote control terminal of the user. Even in such a case, it is
preferable not to display the connection change menu 116 shown in FIG. 9A (even if it is not
displayed, it does not affect the normal operation for viewing the content / program / title
(program) by the user. ).
[0054]
Moreover, although the screen display 111 which FIG. 9A and FIG. 9B show start-up and the
display example of the connection change menu in the television apparatus 101, when the
recorder apparatus 201 is manufactured by the same vendor (Vendor, supply source), a recorder
