1. A home network system for restoring network information, the system comprising:
- at least one slave for outputting a current operation state information indicative of at least one operation state of said at least one slave, the at least one operation state being variable after powering said at least one slave;
a master including a communication module connected to said at least one slave, the master for periodically receiving the current operation state information output from said at least one slave;
a memory storing the received operation state information of said at least one slave; and
a processor checking the state of said at least one slave and transmitting to said at least one slave the stored operation state information when the master determines that said at least one slave has been reset,wherein said at least one slave is restored to a latest state and performs an operation according to the operation state information transmitted from the master.

Abstract
An apparatus for restoring network information for a home network system and a method thereof are disclosed. The apparatus includes at least one slave having means for communicating with an external appliances; a master having means for communicating with the slave, checking a state of the slave, storing state information of the slave, and providing the state information to the slave when the slave is reset; and a home network unit connecting the communication means of the master and the slave to form a network of the master and the slave.

4. A method of restoring network information in a home network system including at least one slave, communicating with a master having a non-volatile memory, the method comprising:
-
outputting, from the at least one slave, operational state information indicative of at least one operation state of the at least one slave the at least one operation state being variable after powering the at least one slave; periodically receiving at the master, the operation state information output from the at least one slave to determine a current operation state of the at least one slave and to determine whether the at least one slave has been reset; storing, in the non-volatile memory, the operation state information of the at least one slave; and transmitting the stored operation state information from the master to the at least one slave when it is determined that the at least one slave has been reset, wherein said at least one slave is restored to a latest state and performs an operation according to the operation state information transmitted from the master. - View Dependent Claims (5)

6. A television receiver serving as a master device for restoring network information in a home network system including at least one slave communicating with the master device, the television receiver comprising:
-
a communication module, connected to the at least one slave, for periodically receiving the operation state information from the at least one slave; memory for storing the operation state information of the at least one slave; and a processor for periodically checking a current operation state of the at least one slave to determine whether the at least one slave has been reset and the processor for transmitting the stored operation state information to the at least one slave, when it is determined that the at least one slave has been reset, wherein said at least one slave is restored to a latest state and performs an operation according to the operation state information transmitted from the master. - View Dependent Claims (7)

8. A master device configured for use in a network system comprising:
-
a communication module configured to periodically receive operation state information from a slave device and to transmit operation state information to the slave device; a memory configured to store the operation state information of the slave device; and a processor configured to; after the operation state information is stored, evaluate a current state of the slave device, determine based on the current state whether the slave device has been reset, and responsive to a determination that the slave device has been reset, transmit the stored operation state information to the slave device, wherein the slave device is restored to a latest state before the reset and performs an operation according to the operation state information transmitted from the master device.

9. A control method for a master device configured for use in a network system comprising:
-
periodically receiving operation state information from a slave device; storing the operation state information; after storing the operation state information, evaluating a current state of the slave device; determining, based on the current state of the slave device, whether the slave device has been reset, and responsive to a determination that the slave device has been reset, transmitting the stored operation state information to the slave device, wherein the slave device is restored to a latest state before the reset and performs an operation according to the operation state information transmitted from the master device.
