Description

수직동기를 이용한 방송방식 판별방법Broadcasting method discrimination method using vertical synchronization

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명 방송방식판별에 대한 블록도.1 is a block diagram of the broadcast mode discrimination of the present invention.

제2도는 본 발명 수직동기의 검출 파형도.2 is a detection waveform diagram of the vertical synchronization of the present invention.

제3도는 본 발명 방송 방식판별에 대한 신호흐름도.3 is a signal flow diagram for the present invention broadcasting system discrimination.

Claims (1)

검출 및 증폭된 수직동기신호가 입력부(4)를 통해 스캔된 후 타임카운터(5), 카운터(6)를 통해 계수되고, 방송방식판별부(8)를 통해 판별하여 출력부(9)를 통해 전송되게 마이콤(11)를 구성하여, 상기 수직동기신호의 1주기를 계수하고, N주기를 계수하여 방송방식을 판별하며, 현지의 방송방식출력데이타와 상기 판별된 방송방식 데이터를 비교하여 동일하면 출력데이타를 그대로 유지하고, 상이하면 상기 판별데이타를 M회 동안 계수 검출하여 상기 출력데이타를 변경하는 것을 특징으로 하는 수직 동기를 이용한 방송방식 판별방법.The detected and amplified vertical synchronization signal is scanned through the input unit 4, counted by the time counter 5 and the counter 6, and discriminated by the broadcasting method discriminator 8, and then output by the output unit 9. The microcomputer 11 is configured to be transmitted, and counts one cycle of the vertical synchronization signal, and counts N cycles to determine a broadcast method. And keeping the output data as it is, if different, counting the discrimination data for M times to change the output data. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
