Abstract

본 발명은 컴팩트 디스크 그래픽 데이타를 스캔할 경우 화면이 깨어지거나 겹쳐지게 되는 현상을 방지하여 안정된 화상을 디스플레이되도록 한 컴팩트 디스크-그래픽 데이타의 스캔방법에 관한 것이다.The present invention relates to a method of scanning compact disc-graphic data in which a stable image is displayed by preventing the screen from being broken or overlapped when scanning the compact disc graphic data.

이를 위하여 마이크로 컴퓨터, 키조작부, 디코더를 포함하여 디스크상에 기록되어 있는 CD-G 데이타를 해독하여 화면에 중첩하여 슈퍼임포우즈 형태로 디스플레이시키는 컴팩트 디스크-그래픽(CD-G) 데이타의 스캔방법에 있어서, 상기 조작부로부터 CD-G 데이타를 스캔하기 위하여 FF키의 입력될 경우 디코더에 뮤트신호를 인가하여 화면상에 CD-G 데이타의 출력을 제거하는 과정, 상기 과정 후 FF 해제키의 입력이 판단되고, 디코더로부터 입력되는 복합동기신호의 현재 구간이 수평동기 구간인지를 판단하여 현재구간이 수평동기 구간으로 판단될 경우 수직동기신호의 에지상태를 검출하는 과정, 상기 과정 후 수직동기신호의 에지가 검출됨이 판단되면 상기 디코더에 인가되어 있는 뮤트신호를 해제하여 CD-G 데이타를 출력시키는 과정으로 이루어 진 것이다.To this end, a method for scanning compact disc-graphic (CD-G) data, including a microcomputer, a key operation unit, and a decoder, which reads CD-G data recorded on a disc and superimposes it on the screen for display in a superimposed form. In the case where the FF key is input to scan the CD-G data from the operation unit, a muting signal is applied to the decoder to remove the output of the CD-G data on the screen. Determining whether the current section of the composite synchronization signal input from the decoder is a horizontal synchronization section, and if the current section is determined to be a horizontal synchronization section, detecting an edge state of the vertical synchronization signal, If it is determined that the detection is detected, the process of releasing the mute signal applied to the decoder to output the CD-G data .

마이크로 컴퓨터, 키조작부, 디고더를 포함하여 디스크상에 기록되어 있는 CD-G 데이타를 해독하여 화면에 중첩하여 슈퍼임포우즈 형태로 디스플레이시키는 컴팩트 디스크-그래픽(CD-G) 데이타의 스캔방법에 있어서, 상기 조작부로부터 CD-G 데이타를 스캔하기 위하여 FF키의 입력될 경우 디코더에 뮤트신호를 인가하여 화면상에 CD-G 데이타의 출력을 제거하는 과정(단계 101,102), 상기 과정 후 FF 해제키의 입력이 판단되고, 디코더로부터 입력되는 복합동기신호의 현재 구간이 수평동기 구간인지를 판단하여 현재 구간이 수평동기 구간으로 판단될 경우 수직동기신호의 에지상태를 검출하는 과정(단계 103∼105), 상기 과정 후 수직동기신호의 에지가 검출됨이 판단되면 상기 디코더에 인가되어 있던 뮤트신호를 해제하여 CD-G 데이타를 출력시키는 과정(단계 106,107)으로 이루어진 것을 특징으로 하는 컴팩트 디스크-그래픽(CD-G) 데이타의 스캔방법.In the method of scanning compact disc-graphic (CD-G) data, including a microcomputer, a key control unit, and a decoder, the CD-G data recorded on the disc is decoded and superimposed on the screen for display in superimposed form. Removing the output of the CD-G data on the screen by applying a mute signal to the decoder when the FF key is inputted to scan the CD-G data from the operation unit (steps 101 and 102). Determining whether the current section of the composite synchronization signal input from the decoder is a horizontal synchronization section and detecting an edge state of the vertical synchronization signal when the current section is determined to be a horizontal synchronization section (steps 103 to 105); After determining that the edge of the vertical synchronization signal is detected, canceling the mute signal applied to the decoder to output CD-G data (step 10). 6,107). A method of scanning compact disc-graphic (CD-G) data. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
