A host device is provided, which includes a network communication unit connected to network; a local communication unit locally connected to a slave device; a virtualization unit to virtualize the slave device as a network device within the network; and a controlling unit to control the virtualized slave device as the network device. Therefore, a developer may implement an application in consideration of a single type of network without considering various physical input and output ports.

Host device and slave device controlling method

An apparatus for controlling devices in one or more home networks is provided. The apparatus includes an authentication unit, a control message generation unit, a control message transmission unit, a response message reception unit, and an information management unit. The authentication unit performs authentication with one or more relay devices each connected to a plurality of devices through a network. The control message generation unit generates a control message in response to a user input. The control message transmission unit transmits the generated control message to a device selected by the user from among the plurality of devices. The response message reception unit receives a response message responding to the transmitted control message. The information management unit manages information about the relay devices and the plurality of devices.

A method and apparatus to reconstruct high-frequency components of an input audio signal. The apparatus includes a frequency inverter to invert the frequency spectrum of the input audio signal, a band pass filter which filters out the higher frequency components of the input audio signal, a converter which shifts the frequency spectrum of the filtered signal to create a correction signal, and an adder which adds the correction signal to the input audio signal to obtain a reconstructed audio signal.

Method and apparatus to reconstruct high-frequency components of an audio signal

Provided is an apparatus and method for reconstructing the high frequency part of audio signal to improve the quality of the audio signal. The apparatus includes a frequency inverter which inverts the frequency of an input signal; a band-pass filter which filters the high frequency part of the inverted signal; a converter which shifts the frequency of the filtered signal so as not to generate aliasing of the input signal and the filtered signal; and an adder which adds the shifted signal to the input signal. Therefore, hearing perception close to the original signal can be achieved.
