Abstract: A method of acquiring an Internet protocol (IP) address to control a standby mode of a set-top box, and the set-top box and a power management server performing the method are disclosed. The method may include determining whether a state of the set-top box changes from a broadcasting state in which a broadcasting service is provided to a passive standby state in which a network connection between the set-top box and a headend providing the broadcasting service is blocked, receiving state information associated with an IP address allocated to the set-top box for the network connection in response to the state of the set-top box changing to the passive standby state, and transmitting, to the set-top box, a state change command to maintain the network connection for the IP address allocated to the set-top box based on the received state information.

Abstract: The present invention is directed to reducing non-fire alarms by distinguishing between smoke caused by an actual fire and non-fire smoke generated in daily life when an event suspected to be a fire occurs. The present invention provides an apparatus and method for determining whether a fire occurs using a smoke detector, which includes a light emitter for generating multiple wavelengths, a light receiver configured to detect light scattered by particles of smoke, and a fire determiner for checking whether the strength of a signal of the detected scattered light exceeds a threshold and generating an alarm, to use characteristics of multiple wavelengths in a photoelectric fire detection apparatus. The fire determiner calculates normalized values by normalizing measured values for the scattered light, and calculates a singular value from the normalized values as a criterion for determining whether the smoke is caused by a fire or a non-fire.
