제2도는 제1도의 동작설명에 대한 신호흐름도로서,2 is a signal flow diagram for the operation description of FIG.

(가)는 마이콤의 스틸키이 처리에 대한 신호흐름도이고,(A) is the signal flow chart for Micom's Steel Key processing,

(나)는 자막처리부의 스틸명령처리에 대한 신호흐름도이다.(B) is a signal flow chart for still command processing of the caption processing unit.

Claims (3)

TV 및 브이씨알의 복합영상신호를 리모콘(4)의 키이모드에 따라 신호선택부(3)로 선택하고 휘도/색도신호 처리부(8)에서 신호처리하여 영상신호처리부(18)를 통해 칼라수상관(19)에 TV 영상신호 및 자막 영상신호를 표시하는 자막 제어 시스템에 있어서, 상기 리모콘(4)으로부터 입력된 스틸 키이 신호에 따라 시스템 전체 동작을 제어하는 마이콤(1)과, 상기 신호선택부(3)로부터 선택된 복합영상신호에서 자막 데이타를 추출하는 캡션데이타 추출부(9)와, 상기 신호선택부(3)의 복합영상신호에서 수평 및 수직동기신호를 분리하는 동기분리부(10)와, 복합영상신호에서 수평 및 수직동기신호를 분리하는 동기분리부(10)와, 상기 마이콤(1)의 제어신호에 의해 구동하여 캡션데이타추출부(9)의 자막 데이타를 처리한 후 동기분리부(10)의 수평 및 수직동기에서 동기시켜 영상신호 처리부(18)를 통해 칼라수상관(19)에 디스플레이하는 캡션처리부(2)로 구성함을 특징으로 한 자막 스틸 제어 시스템.The composite video signal of TV and V-Cal is selected by the signal selector 3 according to the key mode of the remote controller 4, and the signal is processed by the luminance / chromatic signal processor 8 and the color receiver is processed by the image signal processor 18. A subtitle control system for displaying a TV video signal and a caption video signal on (19), comprising: a microcomputer (1) for controlling the entire system operation according to a still key signal input from the remote controller (4), and the signal selection unit ( A caption data extraction unit 9 for extracting caption data from the composite video signal selected from 3), a synchronization separator 10 for separating horizontal and vertical synchronization signals from the composite video signal of the signal selection unit 3, A synchronization separator 10 for separating the horizontal and vertical synchronization signals from the composite video signal, and processing the caption data of the caption data extractor 9 by driving the control signal of the microcomputer 1 and then synchronizing the synchronization signal ( 10) synchronization in horizontal and vertical synchronization On the image signal processor can collar through 18. Any 19 subtitle steel control system characterized in that it consists of a caption processing unit (2) for displaying on. 제1항에 있어서, 캡션처리부(2)는 상기 마이콤(1)으로부터 출력된 제어신호에 의해 구동하여 인터럽트신호를 발생하는 제어신호처리부(13)와, 상기 캡션신호추출부(9)로부터 추출된 자막 데이타를 처리하는 캡션데이타처리부(12)와, 상기 제어신호처리부(13)의 인터럽트신호에 의해 구동하여 프로그램/문자롬(16)의 프로그램 수행에 따라 캡션데이타처리부(12)의 자막 데이타를 데이타램에 저장함과 아울러 그 저장된 데이타를 출력하는 중앙 처리장치(14)와, 상기 중앙처리장치(14)로부터 출력된 자막 데이타를 동기분리부(10)의 수평, 수직동기에 동기 시켜 자막 영상신호를 영상신호스위칭부(18)로 출력하는 온스크린 디스플레이부(15)로 구성함을 특징으로 한 자막 스틸 제어 시스템.2. The caption processing unit (2) according to claim 1, wherein the caption processing unit (2) is driven by the control signal output from the microcomputer (1) to generate an interrupt signal and the caption signal extraction unit (9) extracted from the caption signal extraction unit (9). The caption data processing unit 12 for processing caption data and the caption data processing unit 12 are driven by the interrupt signal of the control signal processing unit 13 to perform caption data of the caption data processing unit 12 according to the program execution of the program / character ROM 16. And a caption video signal by synchronizing the caption data output from the central processing unit 14 with the central processing unit 14 for storing the data in the RAM and outputting the stored data, and the horizontal and vertical synchronization of the synchronization separating unit 10. Caption still control system comprising an on-screen display unit (15) for outputting to the video signal switching unit (18). 키이입력부(11)및 리모콘(4)의 키이신호를 체크하여 TV및 브이씨알의 스틸신호가 검출되면 마이콤(1)은 캡션처리부(2)에 현재 디스플레이되고 있는 자막 데이타 유지신호를 출력하고 캡션처리부(2)는 마이콤(1)의 출력을 체크하여 자막 유지신호가 검출되면 현재 디스플레이되고 있는 자막 정보를 그대로 유지시키는 것을 특징으로 하는 자막 스틸 제어방법.When the key signals of the key input unit 11 and the remote control unit 4 are checked and the still signals of the TV and the VR are detected, the microcomputer 1 outputs the caption data holding signal currently displayed on the caption processing unit 2, and the caption processing unit (2) checks the output of the microcomputer (1) and maintains the currently displayed caption information as it is when the caption retention signal is detected. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
