Abstract

본 발명은 시청자 선택형 자막방송방법 및 그 수신방법에 관한 것으로서, 특히 방송방법은 제어정보와 함께 대사자막의 문자정보 또는 부가문자정보를 입력하는 단계; 제어정보를 모드제어비트 및 패리티비트와 조합하여 2바이트의 제어코드로 발생하고, 문자정보를 모드제어비트 및 패리티비트와 조합하여 한극 완성형 코드로된 문자코드로 발생하는 단계; 상기 제어코드 또는 문자코드를 입력하여 디지탈변조된 자막신호로 출력하는 단계; 및 텔레비젼 신호의 매 필드의 액티브구간 마지막 주사선의 영상신호를 제거한 후에 상기 자막신호를 실어서 송출하는 단계를 구비하는 것을 특징으로 한다. 수신방법은 수신되는 텔레비젼 신호의 동기신호를 검출하고 검출된 수직동기신호에 응답하여 수평동기신호를 카운팅하여 마지막 주사선에 실린 자막신호를 추출하여 디코딩한 후에 자막을 표시한다.The present invention relates to a viewer-selectable caption broadcasting method and a receiving method thereof, and in particular, a broadcasting method includes inputting character information or supplementary character information of a subtitle subtitle together with control information; Generating control codes in combination with a mode control bit and a parity bit in a 2-byte control code, combining character information with a mode control bit and a parity bit to generate a character code in a full-pitch complete code; Inputting the control code or character code and outputting the digitally modulated caption signal; And removing the video signal of the last scan line of the active section of each field of the television signal, and then transmitting and transmitting the subtitle signal. The receiving method detects a synchronizing signal of a television signal to be received, counts a horizontal synchronizing signal in response to the detected vertical synchronizing signal, extracts a subtitle signal on the last scanning line, decodes the subtitle signal, and displays the subtitle.

따라서, 본 발명에서는 액티브 구간의 마지막 주사선에 자막신호를 싣고 이를 수신하기 때문에 영상신호가 안정된 상태에 의해 송수신시 자막신호의 안정성을 향상시킬 수 있어서 전송 및 수신상의 오류를 줄일 수 있다.Therefore, according to the present invention, capturing a caption signal on the last scan line of the active section and receiving the caption signal, the stability of the caption signal during transmission and reception can be improved by stabilizing the video signal, thereby reducing errors in transmission and reception.
