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.

Claims

1. In converting digital broadcast contents including a video signal and an audio signal received via a digital broadcast network in a digital broadcast terminal, a method of converting the digital broadcast contents, comprising:

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.

2. The method of claim 1, further comprising:

a step (c) of extracting a voice signal from the extracted audio signal;

a step (d) of converting the extracted voice signal to a text; and

a step (e) of synchronizing data synthesized in the step (b) and the text together.

3. In converting digital broadcast contents including a video signal and an audio signal received via a digital broadcast network in a digital broadcast terminal, a method of converting the digital broadcast contents, comprising:

a step (a) of selecting a specific section of the digital broadcast contents;

a step (b) of separating the selected section into the video signal and the audio signal;

a step (c) of selecting at least one of at least one or more audio data stored in a memory provided to the terminal; and

a step (d) of synthesizing the separated video signal and the selected at least one audio data together.

4. The method of claim 3, further comprising:

a step (e) of extracting a voice signal from the audio signal extracted in the step (b);

a step (f) of converting the extracted voice signal to a text; and

a step (g) of synchronizing data synthesized in the step (d) and the text together.

5. The method of claim 4, wherein in the step (e), the voice signal is extracted together with time information and wherein the time information is used for the synchronizing step (g).

6. The method of claim 4, further comprising a step (h) of staring data synchronized in the step (g).

7. A digital broadcast terminal comprising:

a digital broadcast receiving unit receiving a digital broadcast signal;

a memory unit storing at least one audio data; and

a control unit separating a specific section of digital broadcast contents received via the digital broadcast receiving unit into a video signal and an audio signal, the control unit synthesizing the video signal and at least one of the at least one audio data stored in the memory unit together.

8. The digital broadcast terminal of claim 7, wherein the control unit extracts a voice signal from the separated audio signal, converts the extracted voice signal to a text and synchronizes the synthesized data and the text together.

9. The digital broadcast terminal of claim 8, wherein the control unit stores the synchronized data in the memory unit.

10. A digital broadcast terminal comprising:

a digital broadcast receiving unit receiving a digital broadcast signal;

a memory unit storing digital broadcast contents received via the digital broadcast receiving unit and at least one or more audio data;

an input unit receiving a selection signal for a specific section of the digital broadcast contents and a selection signal for at least one of the at least one or more audio data; and

a processor having an A/V separating module and an A/V synthesizing module, the A/V separating module separating the selected section into a video signal and an audio signal to output, the A/V synthesizing unit synthesizing the separated video signal and the selected audio data to output.

11. The digital broadcast terminal of claim 10, the processor further comprising a voice recognizing module extracting a voice signal from the separated audio signal, the voice recognizing module converting the extracted voice signal to a text to output.

12. The digital broadcast terminal of claim 11, the processor further comprising a synchronizing module synchronizing the synthesized data outputted from the A/V synthesizing module and the text outputted from the voice recognizing module together.

13. The digital broadcast terminal of claim 10, the processor further comprising an audio editing module extracting a specific data section for a specific one of the at least one or more audio data, the audio editing module delivering the extracted data section to the A/V synthesizing module.
