1. A method of controlling a digital device, the method performed by a controller of the digital device and comprising:
- accessing a relay via a communication unit;
detecting an external device connected to the relay by being located within a preset distance from the relay;
receiving an audio reference data transmission request from the detected external devices via the communication unit,wherein the external device supports a voice recognition function and transmits the audio reference data transmission request to the digital device outputting a real-time broadcast program in response to a preset voice recognition trigger command for controlling the external device, the preset voice recognition trigger command input by a user;
transmitting audio reference data stored in a storage unit to the external device in response to the audio reference data transmission request, wherein the audio reference data comprises audio data extracted from a broadcast signal of the real-time broadcast program and audio data contained in a music content; and
causing the external device to execute an acoustic echo canceler (AEC) function in response to the transmitted audio reference data by matching synch with an audio signal from a speaker of the digital device,wherein when a plurality of digital devices are connected to the relay and when each of the plurality of digital devices includes a speaker, the relay simultaneously transmits audio reference data outputted through a respectively corresponding speaker of each of the plurality of digital devices to the external device, andwherein the audio reference data further comprises audio data corresponding to a section from a current time of an audio signal currently outputted through the speaker of the digital device to a predetermined time elapsed from the current time.
