Abstract

A method of converting digital broadcast contents and digital broadcast terminal having a function of the same are disclosed, by which music in compliance with a user'"'"'s taste can be inserted as a background music by separating an audio signal of digital broadcast contents and by which a text can be displayed as a caption on a screen of the terminal in a manner of converting a voice recognized from a separated audio signal to the text. In converting digital broadcast contents including a video signal and an audio signal received via a digital broadcast network in a digital broadcast terminal, the present invention includes a step (a) of extracting the audio signal and the video signal for a specific section of the digital broadcast contents and a step (b) of synthesizing the extracted video signal with prescribed audio data.

8. A method of converting digital content in a mobile terminal, the method comprising:

storing one or more audio data in a memory of the mobile terminal;

storing at least one digital content including a video signal and an audio signal in the memory;

receiving a signal, via a touch screen of the mobile terminal, for selection of one of the at least one digital content stored in the memory to be converted;

playing the selected digital content, wherein the video signal of the selected digital content is displayed on the touch screen;

displaying a menu on the touch screen enabling a selection of a start point of a specific section of the selected digital content to be converted and enabling a request for selecting at least one audio data of the one or more audio data stored in the memory;

displaying a list of the one or more audio data on the touch screen;

receiving a signal for selection, via the touch screen, of at least one audio data of the one or more audio data displayed on the list;

synthesizing digital content by substituting the audio signal of the selected digital content with the selected at least one audio data and synthesizing the video signal of the selected digital content with the selected at least one audio data;
