A diagram illustrating a caption and voice broadcasting program viewing method.

본 발명에 따른 캡션 및 음성다중 기능을 갖는 TV의 구성은 종래와 동일하므로 설명을 생략하기로 한다.Since the configuration of the TV having the caption and voice multiplexing functions according to the present invention is the same as in the related art, description thereof will be omitted.

이와 같이 구성된 본 발명에 따른 캡션 및 음성다중 기능을 갖는 TV의 음성다중 방송에서의 캡션 제어방법을 도 1 및 도 3을 참조하여 설명한다.A caption control method in a voice multiple broadcast of a TV having a caption and a voice multiple function according to the present invention configured as described above will be described with reference to FIGS. 1 and 3.

먼저, 사용자가 캡션 기능을 사용하고 있는 상태에서 음성다중 전환을 하게 되면 음성 처리부(13)는 음성다중 소리를 전환하여 음성 출력부(17)를 통해 출력하나, 화면상에는 이전 음성에 해당하는 캡션 자막이 디스플레이 되고 있어 소리와 자막이 일치하지 않게 된다.First, when the user is using the caption function and the voice multiple switching is performed, the voice processing unit 13 switches the voice multiple sound and outputs it through the voice output unit 17, but the caption subtitle corresponding to the previous voice is displayed on the screen. Is displayed and the sound and subtitles do not match.

이를 제어하기 위한 방법을 도 3을 참조하여 설명하면, 사용자가 캡션 기능을 선택하여 음성다중 처리된 프로그램을 시청하다가(S30) 음성다중 소리가 전환되면 이를 감지하고(S31), 캡션 기능이 사용중인지를 판단한다(S32). 이때, 캡션 기능이 사용되고 있지 않으면 음성다중만을 전환한다(S33).A method for controlling this will be described with reference to FIG. 3, when a user selects a caption function to watch a voice multi-processed program (S30) and detects a voice multiple sound (S31), and determines whether the caption function is in use. Determine (S32). At this time, if the caption function is not used, only the voice multiplex is switched (S33).

한편, 캡션 기능을 사용중이면 방송 신호중에 음성다중 선택된 언어에 캡션 신호가 있는지를 판단하여(S34), 캡션 신호가 없으면 이전의 캡션 자막을 계속해서 디스플레이 한다(S35). 위의 단계(S34)에서 캡션 신호가 있으면 캡션 디코딩부(14)에서 음성다중 선택된 언어의 캡션 데이타를 추출하고 디코딩하여 영상 합성부(15)로 출력하여 영상 신호와 합성하고, 영상 출력부(16)를 통해 화면상에 디스플레이 한다(S36).On the other hand, if the caption function is in use, it is determined whether there is a caption signal in the voice multi-selected language among the broadcast signals (S34), and if there is no caption signal, the previous caption caption is continuously displayed (S35). If there is a caption signal in the above step (S34), the caption decoding unit 14 extracts and decodes caption data of a language selected in multiple languages, outputs it to the image synthesizing unit 15, synthesizes the image signal, and outputs the image output unit 16. Display on the screen (S36).

이와 같이 사용자가 음성다중 선택을 바꾸면 위의 과정을 반복하여 실시함으로써 선택된 소리에 맞는 캡션자막이 출력되도록 자동으로 제어된다. 또한, 사용자가 음성다중 선택을 한 후 그 선택한 음성에 따른 캡션자막도 수동으로 조정할 수도 있다.As described above, when the user changes the voice multiple selection, the above process is repeated to automatically control the caption subtitle corresponding to the selected sound. In addition, after the user selects multiple voices, caption captions according to the selected voice may be manually adjusted.

이와 같이 조정되는 실예를 도 4를 참조하여 설명하면, 도 4의 (a)화면은 사용자가 현재 시청중인 프로그램의 음성에 해당하는 캡션자막을 디스플레이하여 사용중인 화면이다. 그리고, 도 4의 (b)화면은 사용자가 음성다중 언어를 전환하여 캡션자막도 그에 해당하는 자막으로 전환된 상태이다. 또한, 도 4의 (c)는 사용자가 다시 음성다중 언어를 전환하여 캡션자막도 다시 그 언어에 해당하는 자막으로 전환된 상태를 나타낸 것이다.Referring to FIG. 4, an example of such adjustment is described. The screen (a) of FIG. 4 is a screen in which a user displays a caption subtitle corresponding to the voice of a program currently being viewed. In addition, the screen (b) of FIG. 4 is a state in which the user switches the voice multi-language so that the caption caption is also converted into a corresponding subtitle. In addition, (c) of FIG. 4 illustrates a state in which the user switches back the voice multi-language to convert the caption subtitles into subtitles corresponding to the language.

본 발명에 따른 음성다중 방송에서의 캡션 제어방법은 사용자가 캡션기능 사용시 음성다중을 선택하여 음성 언어를 바꾸면 자동으로 캡션도 바꾸어진 언어에 해당하는 자막으로 바뀌어 디스플레이 되므로 보다 더 효율적인 캡션 및 음성다중 기능을 제공할 수 있다.The caption control method in the voice multiplexing broadcasting according to the present invention is more efficient caption and voice multiplexing function because when the user selects the voice multiplex and changes the voice language when the caption function is used, the caption is automatically displayed as the subtitle corresponding to the changed language. Can be provided.
