The audio output interface 225 outputs audio included in a broadcast signal received through the tuner 240, under control of the controller 210. The audio output interface 225 may output audio (e.g., a voice or sound) input through the communicator 250 or the I/O interface 270. In addition, the audio output interface 225 may output audio stored in the storage 290, under control of the controller 210. The audio output interface 225 may include at least one of a speaker 226, a headphone output terminal 227, and a Sony/Philips digital interface (S/PDIF) output terminal 228. The audio output interface 225 may include a combination of the speaker 226, the headphone output terminal 227, and the S/PDIF output terminal 228.

The power supply 260 supplies power input from an external power source to the internal components 210 to 290 of the image display apparatus, under control of the controller 210. Alternatively, the power supply 260 may supply power input from one or more batteries (not shown) located inside the image display apparatus to the internal components 210 to 290, under control of the controller 210.

The sensor 230 senses a voice of the user, an image of the user, or an interaction of the user, according to an exemplary embodiment.
