A communication device is provided. The communication device includes: a transceiver configured to communicate with a counterpart communication device using a television (TV) white space; a measurer configured to measure power of a signal received from the counterpart communication device; a memory configured to store information corresponding to an initial power level; and a controller configured to determine a transmission power level based on the power measured by the measurer and control the transceiver to communicate with the counterpart communication device while gradually increasing a transmission power of a signal transmitted to the counterpart communication device from the initial power level to the transmission power level. Accordingly, the effect on surrounding broadcast receiving apparatuses can be minimized.

Communication device for communicating using TV white space and method thereof

An image processing apparatus and a method of controlling the same are provided. The image processing apparatus includes: one or more receiving units which receive a plurality of contents; a signal processing unit which outputs a first image frame by processing first content of the plurality of contents and outputs a second image frame by processing second content of the plurality of contents; an output unit which outputs a plurality of contents views by combining the first image frame and the second image frame; and a control unit which, if a sharing restriction command regarding a first contents view from among the plurality of contents views is obtained, restricts matching of a glasses apparatus with the first contents view.

Display apparatus and controlling method thereof

A method and a system for calibrating an input voltage of a voltage controlled oscillator and a digital interface used for calibrating the input voltage. The method includes: setting a lock detection time for tuning a signal phase; setting a lock detection voltage section; setting output frequency values at predetermine spacings; checking connection states of capacitors of the capacitor bank necessary for a lock of the output frequency values; storing information regarding the connection states of the capacitors in the output frequency values; and if one of the output frequency values is determined depending on a change of a channel, setting connection states of the capacitors according to the information regarding the connection state corresponding to the one frequency value. The capacitor bank includes: a predetermined number of capacitors having different capacitances and connected to one another in parallel; and switches connected to the capacitors in series.
