Abstract: A device and method of controlling a sound reproducing device are disclosed. The device includes a communication unit, which transmits and receives data to and from the sound reproducing device; a sensing unit, which detects a motion of the device and obtains azimuth information regarding an azimuth pointed by a pre-set region of the device based on the motion; and a control unit, which receives the azimuth information regarding the sound reproducing device from the sound reproducing device via the communication unit and, if it is determined that the azimuth information regarding the device corresponds to the azimuth information regarding the sound reproducing device within a pre-set range, determines the sound reproducing device as a controlled device.

Abstract: Provided is a control method of a user terminal apparatus and device, for speaker location detection and level control using a magnetic field. The method includes receiving reference magnetic field information generated by at least one speaker, in response to a magnetic field being generated based on the reference magnetic field information by the at least one speaker, detecting the magnetic field generated by the at least one speaker, acquiring location information of the at least one speaker using the detected magnetic field information and the reference magnetic field information, and transmitting the location information of each of the at least one speaker to a source apparatus.

Abstract: A remote controller, a remote controlled electronic device, a remote control system for an electronic device and a remote control method for an electronic device are provided. The remote controller outputs a control code corresponding to a device ID, a device ID setting/change command and an operation command with respect to one or more electronic devices input from a user. The electronic device receives the device ID and/or control code from the remote controller and stores the received device ID. A control unit of the electronic device determines whether to operate in response to a control code received from the remote controller by checking whether the received device ID matches with the stored device ID. An output unit of the electronic device displays the device ID and/or a function in operation.

Abstract: A digital receive apparatus capable of simultaneously receiving a plurality of channels and having a display function control method are provided. The digital receive apparatus capable of simultaneously receiving the plurality of channels according to the present invention selects a plurality of channels among received signals by a user interface according to a mode of displaying a plurality of screens, displays the plurality of selected channels, and controls the display function so that the same channels are not displayed simultaneously. Therefore, when the plurality of channels are received and are displayed using a double screen mode, it is possible to control the display function so that the same channels are not displayed on the left and right screens. Accordingly, it is possible to effectively perform the function of displaying the plurality of screens.

Abstract: The present invention provides a method of compressing a video signal transmission band and a device therefor which can transmit video without any distortion by selecting only the low frequency components of a video signal with most of the information in a block for digital transmission and extracting DC components from this block thereby performing the compression of the transmission band. The method according to the present invention involves a sub-block determining step for determining a sub-block by separating a low frequency area with respect to horizontal, vertical, and temporal (time) axes, an encoding step for decimating respectively the horizontal and vertical axes to 1/M, generating a band compressing block and finally extracting the DC components, and a decoding step for interpolating the DC components to M times after the encoding step and restoring the block in which the DC components were extracted.
