Apparatus and method for changing mode of device

A method for changing a mode of a slave device by a master device, the method comprising:

• generating first information related to a mode activated in the master device;
• and
• transmitting, to a server, the first information,
• wherein the first information is used for identifying at least one slave device synchronized with a mode of the master device and for generating second information related to the mode of the identified at least one slave device, and
• wherein the second information is generated based on information related to a rule applied per mode of the master device and the identified at least one slave device and is used for mode synchronization between the master device and the identified at least one slave device.

A server for changing a mode, the server comprising:

• a receiving unit configured to receive, from a master device, first information related to a mode activated in the master device;
• a controller configured to identify at least one slave device synchronized with a mode of the master device based on the first information, and generate second information related to a mode of the identified at least one slave device based on third information related to a rule applied per mode of the master device and the identified at least one slave device;
• and
• a transmitting unit configured to transmit, to the identified at least one slave device, the second information,
• wherein the second information is used for mode synchronization between the master device and the identified at least one slave device.

A master device for changing a mode of a slave device, the master device comprising:

A method for changing a mode by a slave device, the method comprising:

• receiving, from a server, first information related to a mode of the slave device;
• and
• changing a mode of the slave device based on the first information,
• wherein the first information is generated based on information related to a mode activated in a master device, and is generated based on information related to a rule applied per mode of the master device and at least one slave device to be synchronized with a mode of the master device, and
• wherein the first information is used for mode synchronization between the master device and the at least one slave device.
