Abstract: An image display apparatus is provided. The image display apparatus of the present disclosure comprises: a display; an audio output device; an interface to exchange data with an external sound output device; and a signal processing device which, in a simultaneous sound output mode, configured to output a first audio signal to the audio output device and a second audio signal to the sound output device, and in a single sound output mode, configured to output a third audio signal to the audio output device, wherein a volume level of a first sound based on the first audio signal, which is output from the audio output device, is different from a volume level of a third sound based on the third audio signal which is output from the audio output device. Accordingly, it is possible to reduce the sense of difference in case in which the sound output device and the image display apparatus simultaneously output sound.

Abstract: The image display apparatus of the present disclosure comprises: a display; an audio output device; and a signal processing device, in a simultaneous sound output mode, configured to output a first audio signal based on a first additional delay time to the audio output device and to output a second audio signal based on a second additional delay time, which is lower in level than the first additional delay time, to the sound output device, and in a single sound output mode of the audio output device, configured to output a third audio signal to the audio output device, wherein the first additional delay time is greater than or equal to an additional delay time of a third sound. Accordingly, sound synchronization may be performed in case in which the sound output device and the image display apparatus simultaneously output sound.
