The present invention relates to an image display apparatus and a mobile terminal. The image display apparatus according to one embodiment of the present invention comprises: a display; an interface unit for exchanging data with the mobile terminal; and a control unit for controlling a mirroring related menu including mirroring related server information or content related to the server information such that the mirroring related menu is displayed on the basis of a user input, receiving a mirroring application item from the mobile terminal through the interface unit, and controlling the received mirroring application item such that the received mirroring application item is displayed in the mirroring related menu. Therefore, the mirroring application item received from the mobile terminal can be simply installed and displayed.

Image display apparatus and mobile terminal

A method and apparatus for outputting a supplementary content in a WFD is disclosed. A method for outputting a supplementary content in a WFD may comprise the steps of: after a WFD source is connected to a WFD, transmitting, by the WFD source, an RTSP-based RTSP parameter request message to a WFD sink in order to perform a capability negotiation procedure with the WFD sink; transmitting, by the WFD source, an RTSP parameter response message to the WFD sink in response to the RTSP parameter request message; and after the capability negotiation procedure is performed, transmitting, by the WFD source, a transmission stream, obtained by overlapping and multiplexing a video stream including video data having first resolution and a supplementary stream including supplementary data having second resolution, to the WFD sink, wherein a WFD discovery response frame may include second resolution-related information for determining the second resolution and an RTSP parameter response frame may include the second resolution-related information.

Method and apparatus for reporting battery state in WFD

A method for operating an electronic device according to an embodiment of the present invention includes: entering a content sharing mode capable of sharing content with a first electronic device; outputting first content shared with the first electronic device; entering a content sharing mode capable of sharing content with a second electronic device; determining the authority to decide a display layout, with respect to the second electronic device; transmitting display layout information to the second electronic device upon determining that the second electronic device has the authority to decide the display layout; and receiving, from the second electronic device, display layout determination information including information on output positions of content shared with the first and second electronic devices. Accordingly, it is possible to provide various optimized display layouts of a screen displaying content of connected electronic devices.

Electronic device and method for operating the same

A digital device and a method for controlling the digital device are disclosed in this specification. Herein, according to an exemplary embodiment of the present invention, a targeted device being controlled by a control command received through at least one or more controlling devices includes a first receiving unit receiving content, a second receiving unit receiving a voice signal or text data respective to the voice signal from the controlling device, a decoder decoding the content, a processing unit processing the text data, a controlling unit identifying whether or not text data received from the processing data include a control command, controlling an output of a voice interface in response to a reception of the identified text data, configuring a result screen respective to the processed data and controlling an output of the result screen, and performing control operations so as to execute functions corresponding to the outputted result screen, and an outputting unit outputting the decoded content, the voice interface and its result screen or its function execution screen.

System for controlling device, digital device, and method for controlling same

Disclosed herein is a motor control apparatus and a method thereof. The operation efficiency of a compressor may be maintained by using a sensorless algorithm, sampling a current applied to a motor more than twice within a period of the triangular carrier wave for performing pulse width modulation to calculate a reference voltage, driving the motor according to the calculated reference voltage to improve control resolution, and performing a high-speed operation while reducing a volume of the compressor, without adding a separate hardware when controlling the operation of the motor provided in the compressor at a high speed.

Motor controlling apparatus and method of the same

Disclosed herein is a motor control apparatus and a method thereof. A phase error of the reference voltage output corresponding to a time delay caused by digital control may be compensated to stably control a motor, thereby improving the stability of a system. The phase compensation unit may be provided therein to convert a reference voltage of the synchronous coordinate system into a reference voltage of the stationary coordinate system when controlling the high-speed operation of the motor, thereby compensating a phase error of the reference voltage output, and allowing the motor to be operated at a high speed while maintaining its efficiency and reducing a volume of the compressor.
