Abstract

본 발명은 영상신호의 21번째 수평신호에 포함된 자막 데이터를 프린트하는 인터페이스 장치에 관한 것으로, 일반적으로 사용되는 복합영상처리 회로에서의 클로우즈드 캡션 디코더 자체만으로는 입력된 복합영상신호의 내부에 포함된 자막 데이터를 아스키코드의 형태로 출력하거나 프린터의 인터페이스가 불가능하고 단지영상신호의 형태로 밖에 출력할 수가 없다.The present invention relates to an interface apparatus for printing caption data included in a 21st horizontal signal of a video signal, and the closed caption decoder itself in a commonly used composite image processing circuit itself is included in the input composite image signal. Caption data can not be output in the form of ASCII code or the interface of the printer can be output only in the form of a video signal.

이에따라 본 발명은 상기와 같은 종래의 회로의 결함을 감안하여 복합영상신호에서 21번째의 수평신호에 포함된 자막 데이터를 클로즈드 캡션 디코더 내부의 메모리에 저장하고 사용자로부터의 키 입력 명령에 따라 자막데이타를 프린터 인터페이스부를 통해 프린트할 수 있도록 창안된 것이다.Accordingly, the present invention stores the caption data included in the 21st horizontal signal in the composite video signal in a memory inside the closed caption decoder in consideration of the defect of the conventional circuit as described above, and stores the caption data according to a key input command from the user. It is designed to print through the printer interface.

Claims

If the command input from the user via the keycode is a print command of the subtitle data, turn on the print mode, read the subtitle data stored in the memory inside the closed caption decoder, and print the subtitle through the printer interface circuit. And if the key input command is a stop command for printing, the printer mode is turned off to stop printing of the subtitles. If the key input command is not a print command, the subcommand print interface is executed.

Remote control receiving unit and keyboard unit for receiving subtitle print command or other user's request, remote control receiving unit and keyboard unit for receiving composite video signal, and composite image signal for inputting 21st of composite video signal Closed caption decoder that determines the presence or absence of subtitle data loaded on the horizontal signal, stores the subtitle data in the internal memory, and outputs the subtitles according to a command input through the internal bus interface, or outputs the data stored in the internal memory through the bus interface. And transfers the data for turning on / off the caption output according to the input of the remote control receiver or the keyboard to the closed caption decoder or reads the code of the caption data stored in the memory inside the closed caption decoder. Controlling Print for Subtitles Through the Printer Interface Booth Performed by the microcomputer ⑿ subtitle print interface circuit, characterized in that configured to include.
