The tuner 240 may receive broadcast signals from various sources such as terrestrial broadcasting stations, cable broadcasting stations, satellite broadcasting stations, and Internet broadcasting stations. The tuner 240 may receive broadcast signals from sources such as analog broadcasting stations or digital broadcasting stations. A broadcast signal received through the tuner 240 is decoded (e.g., audio decoding, video decoding, or additional information decoding) and separated into audio, video, and/or additional information. The separated audio, video, and/or additional information may be stored in the image display apparatus under control of the controller 210.

The tuner 240 of the image display apparatus may be single or plural in number. The tuner 240 may be implemented as all-in-one with the image display apparatus or implemented as a separate device (e.g., a set-top box (not shown) having a tuner) electrically connected to the image display apparatus or as a tuner (not shown) connected to the I/O interface 270.

The video processor 280 processes video data received by the image display apparatus. The video processor 280 may include a video decoder configured to decode the video data. In addition, the video processor 280 may perform various types of image processing, such as scaling, noise filtering, frame rate conversion, and resolution conversion.
