Provided is a remote control method and apparatus in a home network system including multiple home devices. The remote control method includes receiving operation state information from the respective multiple home devices, receiving a control command for operation control of at least one of the multiple home devices from a user device, determining a control target home device based on the control command, sending the control command to the determined control target home device, receiving processing result information corresponding to execution of the control command from the control target home device, and transmitting the processing result information to the user device.

Method and apparatus for controlling a home device remotely in a home network system

Disclosed are a temperature compensation apparatus and method. The apparatus includes a reference signal generator that supplies at least one of a first current which is constant regardless of temperature variation and a second current which is proportional to temperature variation, a slope amplifier that determines a first output current having a second temperature coefficient which is a multiple of a first temperature coefficient of the second current, based on the first current and the second current, and a slope controller that determines a second output current having a third temperature coefficient, using a weighted average of the first current and the second current.

Apparatus for compensating for temperature and method therefor

Provided is a Radio Frequency (RF) communication apparatus and a method for detecting power. The RF communication apparatus includes a receiver that receives a segment value indicating one of multiple transmission output power ranges, a power detector that detects a strength of an RF transmission signal in an output power range corresponding to the segment value, and a transmitter that transmits the strength of the detected RF transmission signal. The power detector includes a feedback unit that receives the fed-back RF transmission signal, an RF core unit that generates a Root Mean Square (RMS) of the RF transmission signal, and a converter that converts a current signal corresponding to the RMS of the RF transmission signal into a voltage signal, and converts the converted voltage signal from a differential signal to a single signal.
