Abstract

Disclosed is a method whereby a terminal device outputs an audio signal. The audio signal output method comprises the steps of: receiving a broadcast signal including a normalized audio signal having a preset audio signal size; detecting program genre information from the broadcast signal; detecting a preferred audio signal size corresponding to the detected program genre information; and adjusting the size of the normalized audio

Claims

1. A method of outputting, by a terminal device, an audio signal, comprising steps of:

receiving a broadcasting signal comprising a normalization audio signal having a predetermined audio signal size;

detecting program genre information in the broadcasting signal;

detecting a preference audio signal size corresponding to the detected program genre information; and

adjusting a size of the normalization audio signal so that the size of the normalization audio signal becomes the detected preference audio signal size.

2. The method of claim 1, wherein the step of detecting the preference audio signal size comprises detecting a preference audio signal size which belongs to the preference audio signal sizes and which corresponds to user identification information when the user identification information about the terminal device is received.

3. The method of claim 2, wherein the preference audio signal sizes is generated by learning a program genre-based preference audio signal size corresponding to a user using the user identification information about the terminal device, program genre information about a broadcasting program which is being played back in response to the received broadcasting signal, and a user-selected audio signal size of the broadcasting program which is being played back in response to the received broadcasting signal.

4. The method of claim 1, further comprising steps of:

receiving user input using an audio signal size of the terminal device as the size of the normalization audio signal; and

outputting the normalization audio signal when the user input is received.

5. A terminal device, comprising:

a communication unit which receives a broadcasting signal comprising a normalization audio signal having a predetermined audio signal size;

a detection unit which detects program genre information in the broadcasting signal; and

an audio signal size control unit which detects a preference audio signal size corresponding to the detected program genre information and controls a size of the normalization audio signal so that the size of the normalization audio signal becomes the detected preference audio signal size

6. The terminal device of claim 5, wherein the detection unit detects a preference audio signal size which belongs to the preference audio signal sizes and which corresponds to user identification information when the user identification information about the terminal device is received.

7. The terminal device of claim 6, wherein the preference audio signal sizes is generated by learning a program genre-based preference audio signal size corresponding to a user using the user identification information about the terminal device, program genre information about a broadcasting program which is being played back in response to the received broadcasting signal, and a user-selected audio signal size of the broadcasting program which is being played back in response to the received broadcasting signal.

8. The terminal device of claim 5, further comprising an input unit which receives user input using an audio signal size of the terminal device as the size of the normalization audio signal,

wherein the audio signal size control unit outputs the normalization audio signal when the user input is received.
