Abstract

A method for controlling an audio output and a digital device using the same are provided. The digital device adjusts an output level of an audio signal to a first level if it is determined that an audio output device, which is connected to an audio output terminal of the digital device, is of a first type, and adjusts the output level of the audio signal to a second level if it is determined that the audio output device is of a second type. Therefore, an audio signal is transferred to various types of audio output devices through a single audio output terminal, thereby adjusting the output level of the audio signal to a proper level according to the type of the audio output device and transferring the audio signal having the properly adjusted level.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2009-0117060 filed on Nov. 30, 2009 at the Korean Intellectual Property Office, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] Apparatuses and methods consistent with exemplary embodiments relate to controlling audio output of a digital device, and more particularly, to a method for outputting audio that can be output through a built-in speaker or through an external audio output device and a digital device using the method. Background technique [0004] A digital television (DTV), which is a representative of digital devices, includes speakers installed therein through which audio can be output. In addition, the DTV can transmit audio signals to an audio output device connected through the audio output terminal, thereby enabling audio to be output through the connected audio output device.
