Abstract

본 발명은 캡션인식 메세지 표시방법에 관한 것으로서 보다 상세하게는 캡션 방송을 시청할 시에 캡션 방송이 수신되고 있는지를 인식하여 그 인식된 메세지를 화면으로 표시하여 줌으로써 캡션 방송이 방영되고 있는지의 여부를 외부의 사용자가 쉽게 인식할 수 있게 한 것이다.The present invention relates to a caption recognition message display method, and more particularly, to recognize whether a caption broadcast is being received when watching a caption broadcast, and to display the recognized message on the screen to determine whether the caption broadcast is being broadcast. To make it easier for users of.

특징적인 구성으로는 21번째의 수평 동기신호 입력후 복합 영상신호를 체크하여 캡션 방송의 유무를 판단하고 판단 결과 따라 캡션 방송 상태를 나타내기 위한 캡션 플래그값을 결정하는 제1단계와, 상기 제1단계에서 지정된 캡션 플래그값에 따른 해당 메세지를 표시하도록 표시수단을 제어하면서 채널 가변상태를 체크하는 제2단계와, 상기 제2단계에서 채널이 가변되는 경우 상기 제1단계로 복귀시켜 가변된 채널의 캡션방송유무를 다시 체크하고 채널이 가변되지 않는 경우 현재 방송중인 채널의 캡션 방송상태가 이전과 다른가를 비교하여 다르면 상기에서 결정된 캡션 플래그값을 변경하여 상기 제2단계로 복귀시켜 변경된 내용을 다시 표시하고 같으면 종료하는 제3단계로 이루어짐에 있다.As a characteristic configuration, a first step of determining the presence or absence of caption broadcasting by checking a composite video signal after inputting the 21st horizontal synchronization signal, and determining a caption flag value for indicating a caption broadcasting state according to the determination result, and the first step A second step of checking the channel variable state while controlling the display means to display a corresponding message according to the caption flag value specified in the step; and returning to the first step if the channel is changed in the second step. If the caption broadcasting status is not checked again and the channel is not variable, if the caption broadcasting status of the currently broadcasting channel is different from the previous one, the caption flag value determined above is changed to return to the second step to display the changed contents again. If it is equal to the third step to end.

Claims (1)

21번째의 수평 동기신호 입력후 복합 영상신호를 체크하여 캡션 방송의 유무를 판단하고 판단 결과 따라 캡션 방송 상태를 나타내기 위한 캡션 플래그값을 결정하는 제1단계와, 상기 제1단계에서 지정된 캡션 플래그값에 따른 해당 메세지를 표시하도록 표시수단을 제어하면서 채널 가변상태를 체크하는 제2단계와, 상기 제2단계에서 채널이 가변되는 경우 상기 제1단계로 복귀시켜 가변된 채널의 캡션방송유무를 다시 체크하고 채널이 가변되지 않는 경우 현재 방송중인 채널의 캡션 방송상태가 이전과 다른가를 비교하여 다르면 상기에서 결정된 캡션 플래그값을 변경하여 상기 제2단계로 복귀시켜 변경된 내용을 다시 표시하고 같으면 종료하는 제3단계로 이루어짐을 특징으로 하는 캡션 방송 인식 메세지 표시방법.A first step of determining the presence or absence of caption broadcasting by checking a composite video signal after inputting the 21st horizontal synchronization signal, and determining a caption flag value for indicating a caption broadcasting state according to the determination result; and the caption flag specified in the first step. A second step of checking the channel variable state while controlling the display means to display the corresponding message according to the value; and if the channel is changed in the second step, returning to the first step to check whether there is a caption broadcasting of the variable channel again. If it is checked and the channel is not variable, if the caption broadcasting state of the currently broadcasting channel is different from the previous one, the caption flag value determined above is changed to return to the second step, and the changed content is displayed again. Caption broadcast recognition message display method characterized in that consisting of three steps. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
