[First operation example]
Hereinafter, the adjustment operation of the monitors M1 to Mn by the controller 12 of the monitor system 1 shown in FIG. 1 will be described.
FIG. 5 is a flowchart for explaining the operation example.
Step ST1:
The control circuit 35 of the controller 12 shown in FIG. 3 determines whether or not a monitor selection instruction is input via the operation unit 33.
In the present embodiment, the monitor selection instruction is generated, for example, when the user operates the buttons SINGLE, GROUP, ALL shown in FIG.
For example, when the user operates the button SINGLE, among the LEDs 47, the LED corresponding to SIGLE is turned on. In this state, when the user uses the numeric keypad 46 to input one number of the monitors M1 to Mn, a monitor selection instruction specifying the monitor M1 to Mn having the one input number is generated.
For example, when the user operates the button GROUP, the LED corresponding to the GROUP among the LEDs 47 is lit. In this state, when the user inputs a plurality of numbers of the monitors M1 to Mn using the numeric key 46, a monitor selection instruction is generated in which the monitors M1 to Mn of the input plurality of numbers are specified as a group.
Further, for example, when the user operates the button ALL, the LED corresponding to ALL of the LEDs 47 is lit, and a monitor selection instruction indicating ALL is generated.

Step ST2:
The control circuit 35 exchanges mutual IP (Internet Protocol) addresses via the network 10 with the monitors M1 to Mn specified by the monitor selection instruction input in step ST1.
Thereby, the connection via the network 10 between the controller 12 and the specified monitors M1 to Mn is established.
Then, the control circuit 35 writes the monitor IDs of the connected monitors M1 to Mn in the memory 34.

Step ST3:
The control circuit 35 determines whether or not a monitor adjustment instruction has been input from the operation unit 33. If it is determined that the input has been input, the control circuit 35 proceeds to step ST4.
In the present embodiment, the monitor adjustment instruction is generated when the user operates the image quality adjustment knob 45 shown in FIG.

Step ST4:
The control circuit 35 generates control data CNT corresponding to the monitor adjustment instruction input in step ST3, and transmits control data to the monitors M1 to Mn established in step ST2 from the interface 31 shown in FIG. 4 via the network 10. Send CNT.
Monitors M <b> 1 to Mn shown in FIG. 2 input the control data CNT through the interface 24 and write it into the memory 25.
Thereafter, the control circuit 26 adjusts the image quality of the video signal C displayed on the display 22 based on the control data CNT read from the memory 25.
In this embodiment, when the buttons GROUP and ALL are operated in step ST1, the control data CNT is transmitted to the plurality of monitors M1 to Mn, and these are controlled collectively.

[Second operation example]
Hereinafter, an operation example when the controller 12 is powered on will be described.
FIG. 6 is a flowchart for explaining the operation.
Step ST21:
When the control circuit 35 of the controller 12 shown in FIG. 3 determines that the power is turned on, the process proceeds to step ST22.

Step ST22:
The control circuit 35 transmits a participation notification PN from the interface 31 to the network 10.
Among the monitors M1 to Mn, when the control circuit 26 shown in FIG. 2 of the power-on monitor receives the participation notification PN, it transmits a participation request PR including its own monitor ID to the controller 12 via the network 10. To do.

Step ST23:
The control circuit 35 of the controller 12 determines whether or not the participation request PR has been received. If it is determined that the participation request PR has been received, the process proceeds to step ST24.

Step ST24:
The control circuit 35 determines whether or not the participation request PR determined to have been input in step ST23 is the first participation request PR after the controller 12 is turned on, and determines that it is the first participation request PR. Then, it progresses to step ST27, and when that is not right, it progresses to step ST25.

Step ST25:
The control circuit 35 determines whether or not the monitor ID included in the participation request PR input in step ST23 is stored in the memory 34. If it is determined that the monitor ID is stored, the control circuit 35 proceeds to step ST25. The process returns to step ST23.

Step ST26:
The control circuit 35 determines whether or not the operation unit 33 has input any operation by the user after turning on the power of the controller 12 this time. If it is determined that the operation has been input, the control circuit 35 returns to step ST21. Then, the process proceeds to step ST27.

Step ST27:
The control circuit 35 exchanges IP addresses with the monitors M1 to Mn of the monitor ID included in the participation request PR received in step ST23, and establishes a connection.

As described above, in the monitor system 1, the controller 12 stores the monitor IDs of the connected monitors M1 to Mn. Then, when the power is turned on, the controller 12 automatically returns the connection with the monitors M1 to Mn and the control state of the monitors M1 to Mn to the state before the power is turned off based on the stored monitor ID.
As a result, the administrator of the controller 12 does not need to perform an operation to turn on the power of the controller 12 and return to the state before turning off, thereby reducing the burden.

In the monitor system 1, as shown in FIG. 6, the controller 12 establishes a connection with the monitors M1 to Mn that have received the participation request PR for the first time after the power is turned on (step ST24). It can be immediately connected to any of the monitors M1 to Mn after being raised, and this can be controlled. That is, the controller 12 can shorten the time when it is not connected to any of the monitors M1 to Mn after the power is turned on.
In the monitor system 1, the controller 12 is connected to a monitor different from the monitors M1 to Mn connected before the power is turned off, and then receives a participation request PR from the monitors M1 to Mn connected before the power is turned off. When received, the connection is switched to the monitor. Thereby, it returns to the state before power-off.

In the monitor system 1, the controller 12 is operated by a user on another already connected monitor before receiving the participation request PR from the monitors M <b> 1 to Mn connected before the power is turned off. Does not switch connections. Thereby, the connection relation suitable for the user's actual operation can be constructed.
In addition, since the monitor system 1 automatically establishes a connection with the monitor that first receives the participation request PR, when there is a single monitor M1 to Mn, the time until the connection is established after the power is turned on can be shortened.

The present invention is not limited to the embodiment described above.
That is, those skilled in the art may make various modifications, combinations, subcombinations, and alternatives regarding the components of the above-described embodiments within the technical scope of the present invention or an equivalent scope thereof.
