Abstract

본 발명은 캡션(caption)기능을 내장한 티브이 및 브이씨알의 자막 문자 스틸에 있어서 브이씨알의 스틸 모드를 자동으로 판단하여 브이씨알 스틸 기간동안 디스플레이되는 자막용 문자를 스틸하도록 한 자막 스틸 제어 시스템의 노말/스틸 모드 제어 방법에 관한 것으로, 종래에는 브이씨알의 스틸 모드에서 브이씨알의 스틸 키이를 마이콤에서 판단하여 캡션처리부를 제어하므로써 브이씨알의 스틸 키이의 키이 모드를 티브의 마이콤에서 판단할 수 있도록 프로그램하여야만 판단 가능하며, 브이씨알의 스틸 키이모코드를 마이콤에서 판단하도록 한다면 마이콤에서는 프로그램 사이즈에 문자게 있고, 스틸 키이 모드가 브이씨알의 변경되면 그에 대한 대책이 없는 등의 문제가 있었다.The present invention provides a caption still control system for automatically capturing a still-captioned character displayed during a V-Still period by automatically determining a still mode of a V-Cal in a subtitle character still of a TV or V-Cal having a caption function. The present invention relates to a normal / steel mode control method. In the related art, a microcom's steel key is judged by the microcomputer in the still mode of the VRC to control the caption processing unit so that the microcomputer can determine the key mode of the steel key of the VRC. If the program can be judged, and if Microcom's Steel Key Emo Code is to be judged by MICOM, there are problems such as the size of the program in MICOM, and there is no countermeasure when the Steel Key mode is changed.

이와 같은 종래의 결함을 감안하여 본 발명은 복합영상신호에서 수직동기신호와 수평동기신호를 분리하여 먼저 수직동기를 판단한 후 이를 기준으로 수직동기 이후에 있는 동화펄스의 갯수를 카운트하여 브이씨알의 스틸 모드 유.무를 판단하여 브이씨알의 스틸 모드인 경우에 자막용 문자데이타를 에러없이 디스플레이하는 효과가 있다.In view of such a conventional defect, the present invention separates the vertical synchronizing signal and the horizontal synchronizing signal from the composite video signal, and then judges the vertical synchronizing first, and then counts the number of moving picture pulses after the vertical synchronizing based on this. It is effective to display the subtitle character data without error in the still mode of VRC by determining the mode.

Claims (2)

마이콤(1)에서 복합영상신호중에 수직귀선기간에 동화펄스를 체크하여 브이씨알의 스틸 모드 유.무를 판단하는 것을 특징으로 하는 자막 스틸 제어 시스템의 노말/스틸 모드 제어방법.A normal / still mode control method for a closed captioned still control system, characterized in that the microcom (1) checks a moving picture pulse in a vertical retrace period of a composite video signal to determine whether there is still mode for V-CAL. 제1항에 있어서, 마이콤(1)에서 수평, 수직동기신호를 입력받아 동기신호를 검출하여 동기신호가 있으면 다시 수직동기신호를 검출하여 수직동기신호가 있으면 수직동기신호이후의 등화펄스기간(3H)을 체크하고 그 기간에 동기가 있는가를 판단하여 동기가 없으면 브이씨알의 스틸모드라는 것을 판단함을 특징으로 하는 자막 스틸 제어 시스템의 노말/스틸 모드 제어방법.The equalization pulse period (3H) after the vertical synchronization signal according to claim 1, wherein the microcomputer 1 receives the horizontal and vertical synchronization signals, detects the synchronization signal, and if there is a synchronization signal, detects the vertical synchronization signal again. ) And determine whether there is a motive for the period, and if there is no motive, the normal / still mode control method of the subtitle still control system, characterized in that it is determined. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
