A repeater, broadcast transmitting system, and method for relaying a broadcast signal between a gateway apparatus and a client apparatus are provided. The repeater includes a first interface which is configured to be connected to a gateway apparatus via a Wi-Fi communication protocol and is configured to receive a broadcast signal from the gateway apparatus; and a second interface which is configured to be connected to a client apparatus via the Wi-Fi communication protocol and is configured to transmit the broadcast signal to the client apparatus, wherein the first interface and the second interface use different frequency bands.

Repeater, broadcast transmitting system and method for relaying broadcast signal

Provided are a three dimensional (3D) display apparatus, a method of setting up a graphic user interface (GUI) thereof, and 3D glasses. The method of providing a GUI of the 3D display apparatus operating in association with the 3D glasses includes receiving a signal including battery information from the 3D glasses, generating a GUI related to the battery information of the 3D glasses, using the battery information contained in the received signal, and displaying the generated GUI on a screen of the 3D display apparatus.

Method of providing 3D image and 3D display apparatus using the same

A display apparatus, three-dimensional (3D) glasses, and a display system including the display apparatus and the 3D glasses are provided. The 3D glasses which interwork with an external display apparatus include: a wireless receiver which receives a sync signal and audio signals from the external display apparatus; a shutter driver which drives shutters according to the received sync signal; and an audio output part which processes and outputs the received audio signal. Thus, users can individually enjoy contents without interfering with one another by selecting and listening to audio corresponding to an image viewed through the display apparatus.

Display apparatus, 3D glasses, and display system including the same

A repeater and method of controlling thereof are provided. The repeater includes: a first interface unit which is configured to be connected to a gateway apparatus via a Wi-Fi communication protocol; and a second interface unit which is configured to be connected to a client device via the Wi-Fi communication protocol, wherein at least one of the first and second interface units comprises a filter which filters different frequency bands.

Repeater

An access point and a method for connecting wireless communication thereof are provided. The method includes, if a connecting device is connected to the access point, registering information of the connecting device, if the connecting device transmits a first signal in response to a beacon message of the access point after having been disconnected from the access point and connected to a host device, determining whether the connecting device is already registered using the first signal, and, if it is determined that the connecting device is already registered, connecting to the host device via the wireless communication connection.

Access point and method for connecting wireless communication

Apparatus, method, and system for synchronization and a three-dimensional (3D) display apparatus using the same are provided. The 3D display apparatus includes: a power generator which generates power based on a received alternating current (AC) power signal, a detector which detects zero crossing points of time of the received AC power signal, and a controller which generates a reference signal based on the detected zero crossing points of time and transmits the reference signal to at least one other 3D display apparatus.

Apparatus, method and system for synchronization and 3D display apparatus using the same

Disclosed are a display apparatus, three-dimensional (3D) glasses and a control method thereof. The method of controlling three-dimensional (3D) glasses for a display apparatus includes: synchronizing clocks for communicating with the 3D glasses; generating drive timing information for driving shutters of the 3D glasses from the synchronized clocks and a frame sync signal of a displayed image; and transmitting a glasses control message, comprising the drive timing information, to the 3D glasses.

Display apparatus, 3D glasses, and control method thereof

A wireless communication method, and a wireless communication apparatus and wireless communication system using the same. The wireless communication method includes pairing with a specific device, extracting a media access control (MAC) address of the specific device, and communicating with the specific device. Accordingly, even when a MAC address of a counterpart device is not known, pairing with the counterpart device can be performed without interference with other devices.

Wireless communication method, and wireless communication apparatus and wireless communication system using the same

A method and apparatus for establishing a communication channel provided. The apparatus includes a storage unit which stores a communication channel search starting point for an address of the apparatus; and a controller which searches a communication channel at the communication channel search starting point set in the address of the apparatus. Accordingly, the probability of establishing the same communication channel may be reduced. As a result, inter-channel interference may also be reduced so that image deterioration may be prevented.

Method for establishing communication channel and image receiving apparatus using the same

There is provided a combined TV and FM radio receiver for selectively receiving TV and FM radio signals via a single tuner using a digital intermediate frequency (IF) stage. The receiver includes a tuner that selects TV band or FM radio band signals and converts the selected signals into IF signals or primary sound IF signals; an IF processor that generates local oscillating signals depending on whether a current mode is a TV mode or an FM radio mode, and converts the IF signals and/or primary sound IF signals, into baseband signals and secondary sound IF signals, respectively; a video demodulator that extracts video signals; an audio demodulator that extracts TV audio signals and FM radio signals according to TV sound or FM radio mode data; and a controller that controls the tuner, and the IF processor, and applies the TV sound or FM radio mode data to the audio demodulator.

Apparatus and method for receiving television and radio broadcasting signals using a single tuner

An automatic gain control apparatus for a video signal and adjusting method thereof, An RF(Radio Frequency) automatic gain control apparatus receives a reproduced video signal from a demodulator, controlling a gain of an RF amplifier according to the reproduced video signal. An IF(Intermediate Frequency) automatic gain control apparatus receives a reproduced video signal from a demodulator, controlling a gain of an IF amplifier according to the reproduced video signal. In the meantime, a RF automatic gain control compensating unit detects an input signal provided to the IF amplifier, checking whether the detected IF input signal meets a reference level, controlling for raising a voltage of the RF automatic gain control apparatus if the detected IF input signal is lower than the reference level, controlling for lowering a voltage of the RF automatic gain control apparatus if the detected IF input signal is higher than the reference level.
