Abstract

본 발명은 시청자 선택형 자막신호의 부채널 언어판별방법에 관한 것으로서, 특히 텔레비젼신호의 매필드마다 한 주사선에 자막신호를 실어서 송신하는 시청자 선택형 자막방송을 수신하는 방법에 있어서, 수신되는 텔레비젼 신호의 수직동기신호를 검출하여 짝수 필드를 검출하는 단계; 검출된 필드상의 자막신호의 유무를 검출하는 단계; 자막신호로부터 추출된 자막데이터에 의해 제어코드인지 문자코드인지를 체킹하는 단계; 및 문자코드인 경우에는 자막데이터의 문자코드값을 판별하여 해당 언어를 판별하는 단계를 구비한 것을 특징으로 한다,The present invention relates to a subchannel language discrimination method for a viewer selectable caption signal, and more particularly, to a method for receiving a viewer selectable caption broadcasting in which caption signals are transmitted on one scanning line for every field of a television signal, Detecting an even-numbered field by detecting a vertical synchronization 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; And a step of discriminating the character code value of the caption data and determining the language if the character code is a character code,

따라서, 본 발명에서는 부채널을 통해 수신된 문자코드의 언어종류를 판별할 수 있다.Therefore, in the present invention, the language type of the character code received through the subchannel can be determined.
