Abstract

Each of a plurality of displays transmits an operation state of the display to a management device. The management device stores the operation states corresponding to the plurality of displays in a memory. Based on the operation states corresponding to the plurality of displays and stored in the memory, the management device transmits a command for causing the display to perform the same operation as the other displays. Each of the plurality of displays changes the operation state of the display based on the command provided from the management device.

Claims

1. A network system comprising a plurality of displays, and a managing device, wherein

each of said plurality of displays includes:

a screen,

a first interface for communicating with said managing device, and

a first processor for transmitting an operation state of said display through said first interface to said managing device and controlling said display based on a command provided from said managing device; and

said managing device including;

a second interface for communicating with said plurality of displays,

a memory for storing said operation states corresponding to said plurality of displays, respectively, and

a second processor for transmitting, through said second interface, to one of said displays said command for causing said one of the displays to perform the same operation as the other displays, based on said operation states, stored in said memory, corresponding to said plurality of displays.

2. The network system according to claim 1, wherein

said managing device is a display including a screen;

and

said second processor operates to store the operation state of the managing device in said memory, and

to cause said managing device to perform the same operation as the other displays based on the operation states corresponding to said managing device and said plurality of displays.

3. The network system according to claim 1, wherein

said second processor determines whether the operation states corresponding to said plurality of displays are the same operation state or not, with reference to said memory, and

when a difference is present between said operation states, said second processor transmits said command to said display other than the displays corresponding to the largest value in number by making a comparison in number between said displays corresponding to said respective different operation states.

4. The network system according to claim 1, wherein

said network system further comprises a contents output device for providing contents,

each of said displays further includes a third interface for communicating with said contents output device, and

said first processor displays on said screen the contents received from said contents output device through said third interface.

5. The network system according to claim 4, wherein

said third interface includes a plurality of input terminals, and

said operation state includes a state of selection of the input terminal receiving said contents being displayed on said screen.

6. The network system according to claim 4, wherein

said operation state includes an attribute of an input signal of said contents being displayed on said screen.

7. The network system according to claim 6, wherein

when the attribute of the input signal of said one of the displays is different from the attributes of the input signals of the other displays, said first processor changes the input destination of said contents to another input destination and then restores the input destination based on said command.

8. The network system according to claim 1, wherein

said operation state includes an on/off state of a power.

9. The network system according to claim 1, wherein

when said managing device is powered on, said second processor transmits said command to said display through said second interface based on the operation state corresponding to said plurality of displays.

10. The network system according to claim 1, wherein

said network system further comprises a management terminal for communicating with said managing device, wherein

said second processor receives said operation state from said plurality of displays after transmitting said command,

determines whether said plurality of displays are in said same operation state or not, and

when said plurality of display devices are not in said same operation state, transmits an alarm to said management terminal through said first communication interface.

11. A network system comprising a plurality of displays, wherein

each of said plurality of displays includes:

a screen,

a first interface for communicating with the other displays,

a first processor for transmitting an operation state of one of said displays to the other displays and receiving the operation states from the other displays through said first interface, and

a memory for storing said operation states corresponding to said plurality of displays; and

said first processor causes said display to perform the same operation as the other displays based on said operation state corresponding to said plurality of displays.

12. A managing method in a network system including a plurality of displays and a managing device, comprising the steps of:

transmitting, by each of said plurality of displays, an operation state of said display to said managing device;

storing, by said managing device, said operation states corresponding to said plurality of displays in a memory;

transmitting, by said managing device, said command for causing said display to perform the same operation as the other displays based on said operation states corresponding to said plurality of displays; and

changing, by each of said plurality of displays, the operation state of said display based on a command provided from said managing device.

13. A managing method in a network system including a plurality of displays, comprising the steps of:

transmitting, by each of said plurality of displays, an operation state of said display to the different display;

storing, by each of said plurality of displays, said operation states corresponding said plurality of displays in the memory; and

changing, by each of said plurality of displays, the operation state of said display to the same operation state as the other displays, based on said operation states that corresponding to said plurality of displays.
