Hereinafter, a method of extracting highlight sections for a specific file stored in the memory 160 of the portable terminal, a file being reproduced in the portable terminal, DMB broadcasting, or the like will be described.

4 is a flowchart provided to explain a method of operating a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 4, the controller 180 displays a highlight menu including a highlight extraction function on the display unit 151 according to a user command (S410). The highlight menu may be displayed when playing a music file or a video file or watching a sports relay broadcast.

When an input for selecting a highlight extraction function is received from the highlight menu (S420), the controller 180 extracts and analyzes information on a voice waveform of a file being played or a selected file (S430). The music file may be composed of a header region and an audio file region, and the video file may be composed of a header region, an audio file region, and a video file region. Can be. The header area of the file stores information about the file such as the file type, file length, and file decoding method. In the case of a music file or a video file, frequency information of a voice waveform may be stored in a part of the header area. It may be stored for the basic information of the voice waveform.

By using the information on the audio waveform stored in the header area as described above, the information on the audio waveform can be analyzed without reproducing the audio track of the music file or the video file.

The controller 180 analyzes the information on the speech waveform and determines whether there is a section in which the pattern of the speech waveform is repeated (S440). In the case of most music files, there are choruses repeated in sections 1 and 2, and the choruses can be estimated as the user's favorite highlight section, and the repeated section can be extracted as the highlight. Therefore, as a result of analyzing the voice waveform, when there is a section in which the pattern is repeated, the section in which the pattern is repeated may be extracted as a highlight section (S460).

As a result of analyzing the pattern of the speech waveform, if there is no section in which the pattern is repeated, the high frequency section of the speech waveform is extracted and the extracted high frequency section is extracted as a highlight section (S450).

The file extracted as the highlight section may be reproduced by the display unit 151 and automatically stored in the memory 160 (S470). Alternatively, when a storing function is input by the user's selection, the controller 180 can store the extracted highlight section in the memory 160.

5 is a flowchart provided to explain a method of operating a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 5, as described above with reference to FIG. 4, the controller 180 displays a highlight menu including a highlight extraction function on the display unit 151 according to a user command (S510).

When an input for selecting a highlight extraction function is received in the highlight menu (S520), the controller 180 separates and extracts an audio signal and a video signal of a file (S530). The file may be a video file in which an audio signal and a video signal are combined. For example, the file may be a sports relay broadcast.

The controller 180 detects a slow motion through frame analysis of the video signal (S540). In this case, the frame analysis of the video signal analyzes the number of frames reproduced per second, and when the number of frames reproduced per second is smaller than a predetermined value, it is determined as slow motion. For example, if a video signal having a frame number of 30 frames per second is changed to 15 frames per second in a predetermined section, the changed section may be determined as slow motion.

In the case of sports broadcasting, when a highlight scene comes out, a highlight section may exist in a section before slow motion because the highlight scene is reproduced in slow motion.

Therefore, when the slow motion is detected, the audio signal is analyzed in a predetermined section before the slow motion (S550).

The audio signal is analyzed to extract a speech waveform, and the extracted high-frequency section is extracted as a highlight section (S560).

In the case of the highlight section, the high frequency section of the speech waveform can be extracted as the highlight section because the probability of the high frequency speech waveform being higher than that of other sections due to the applause or the cheering sound of the audience.

In addition, the present invention is not limited thereto, and a highlight section may be extracted by analyzing a sound waveform to detect a specific sound. The specific sound may include the clapping sound or the cheering sound of the crowd described above.

Thereafter, as described above with reference to FIG. 4, the file extracted as the highlight section may be reproduced by the display unit 151 and automatically stored in the memory 160 (S570). Alternatively, when a storing function is input by the user's selection, the controller 180 can store the extracted highlight section in the memory 160.

In the highlight setting window 640, the length of the section to be extracted as the highlight may be set by setting the length of the front and the back of the section to be extracted as the highlight or the scene extracted as the highlight. Although not shown, a frequency range to be extracted as a highlight section may be set.

After the setting value is changed as described above, when the OK button 641 is pressed, the highlight submenu window 630 is displayed after the set value is changed, and when the CANCEL button 642 is pressed, the set value is not changed. Instead, the highlight submenu window 630 is displayed.

Referring to FIGS. 7A and 7B, when the highlight recording menu 631 is selected, the controller 180 may extract a highlight section based on the highlight setting value and store the highlight section in the memory 160. . In this case, even when the highlight recording menu 631 is selected during a broadcast being broadcast in real time, such as sports relay, the broadcast signal or broadcast related information received to extract the highlight section of the entire broadcast is temporarily stored in the memory 160. Can be stored as.

When there is an input for selecting the highlight recording menu 631, the highlight icon 651 indicating that the highlight is extracted is displayed on the display unit 151.

In addition, the start recording icon 653 is temporarily displayed on the display unit 151 at the time when the extraction is started as the highlight section, and as shown in FIG. The finish recording icon 655 may be temporarily displayed on the display unit 151.

The extracted highlight section may be automatically stored in the memory 160. The user may separately execute a program in which a video file of the portable terminal is stored and play back the stored highlight section.
