Abstract

본 발명은 시청자 선택형 자막신호의 부채널 언어판별 표시방법에 관한 것으로서, 특히 텔레비젼신호의 매필드마다 한 주사선에 자막신호를 실어서 송신하는 시청자 선택형 자막방송을 수신하는 방법에 있어서, 수신되는 텔레비젼 신호의 수직동기신호를 검출하는 짝수 필드를 검출하는 단계; 검출된 필드상의 자막신호의 유무를 검출하는 단계; 자막신호로부터 추출된 자막데이터에 의해 제어코드인지 문자코드인지를 체킹하는 단계; 문자코드인 경우에는 자막데이터의 문자코드값을 판별하여 등록된 언어인가르 판별하는 단계; 및 등록된 언어가 아니면 미등록언어임을 스크린 상에 표시하는 단계를 구비한 것을 특징으로 한다.The present invention relates to a subchannel language discrimination display method of a viewer selectable caption signal, and more particularly, to a method of receiving a viewer selectable caption broadcasting which transmits and captures a caption signal on one scanning line for every field of a television signal, Detecting an even-number field for detecting a vertical synchronization signal of the video signal; Detecting presence or absence of a caption signal on the detected field; Checking whether a control code or a character code is detected based on the caption data extracted from the caption signal; If the character code is a character code, discriminating a character code value of the caption data and discriminating a registered language; And displaying the non-registered language on the screen if the registered language is not the registered language.

따라서, 본 발명에서는 부채널을 통하여 수신된 언어가 미등록언어일 경우에는 이를 표시함으로써 시청자가 인지할 수 있게 된다.Accordingly, in the present invention, when the language received through the subchannel is an unregistered language, the viewer can recognize the language by displaying it.
