Electronic device, electronic device system control method and electronic device system

An electronic device (controller) enabled to connect a different electronic device so as to control said different electronic device remotely, said (controller) device, comprising:

• a connection state storing unit for storing connection information of said different electronic device;
• a communication route detecting unit for detecting a communication route between said device (controller) and said electronic device based on said connection information stored in said connection state storing unit;
• and
• a notifying unit for notifying a user of said communication route detected by said communication route detecting unit,
• said device (controller) configured to send a flag-set command to one or more electronic devices connected along said communication route, in order to set a flag that is stored in each of said one or more electronic devices.

An electronic device (controller) enabled to connect a different electronic device so as to control said different electronic device remotely, said device (controller), comprising:

• a communication route detecting unit for detecting a communication route between said device (controller) and said electronic devices;
• a disconnection detecting unit for detecting disconnection of said communication route detected by said communication route detecting unit;
• and
• notifying unit for notifying a user of a result of detection by said communication route detecting unit or by said disconnection detecting unit,
• said device (controller) configured to send a flag-set command to one or more electronic devices connected along said communication route, in order to set a flag that is stored in each of said one or more electronic devices,
• said device (controller) further configured to send a flag-reset command to said one or more electronic devices, in order to clear each said flag.

An electronic device (controller) enabled to connect a different electronic device so as to controls said different electronic device remotely, said device (controller), comprising:

• a connection state storing unit for storing connection information of said different electronic device connected to a network;
• a communication route detecting unit for detecting a communication route between said device (controller) and said electronic devices based on said connection information stored in said connection state storing unit;
• disconnection detecting unit for detecting disconnection of said communication route detected by said communication route detection unit;
• and
• a notifying unit for notifying the user of a result of detection by said communication route detecting unit or by said disconnection detecting unit,
• said device (controller) configured to send a flag-set command to one or more electronic devices connected along said communication route, in order to set a flag that is stored in each of said one or more electronic devices,
• said device (controller) further configured to send a flag-reset command to said one or more electronic devices, in order to clear each said flag.

An electronic device comprising:

• a communication route flag data store having a first value when said electronic device is connected along a communication route that is connected between a first electronic device and a second electronic device, and having a second value when said electronic device is not connected along a communication route that is connected between a first electronic device and a second electronic device;
• and
• a display unit for indicating the value that is stored in said communication route flag data store,
• said electronic device configured to receive a flag-set command and a flag-reset command from a different electronic device (controller), to store said first value in said communication route flag data store in response to receiving said flag-set command, and to store said second value in said communication route flag data store in response to receiving said flag-reset reset command.
