The communicator 250 may transmit and receive data or a signal to and from an external device or server under control of the controller. The controller 210 may transmit/receive content to/from the external device connected through the communicator 250, download an application from the external device, or perform web browsing through the communicator 250. The communicator 250 may transmit and receive data or a signal by at least one scheme of a wireless local area network (WLAN) (e.g., Wi-Fi), Bluetooth, and wired Ethernet in correspondence with the performance and structure of the image display apparatus. In addition the communicator 250 may include a combination of a wireless local area network (WLAN) interface 251, a Bluetooth interface 252, and a wired Ethernet interface 253. The communicator 250 may further include other short-range communication interfaces (e.g., a near field communication (NFC) interface, not shown) and a Bluetooth low energy (BLE) communication interface (not shown), in addition to the Bluetooth interface 252.

The tuner 240 may tune and select only a frequency of a channel which the image display apparatus desires to receive from among a number of frequency components through amplification, mixing, resonance, and the like of a broadcast signal received in a wired or wireless manner. The broadcast signal includes audio, video and additional information (e.g., electronic program guide (EPG)).

The tuner 240 may receive a broadcast signal in a frequency band corresponding to a channel number according to a user input (e.g., a control signal received from a control device, examples of the control signal are a channel number input, a channel up/down input, and a channel input on an EPG screen image).
