복합 영상 신호의 직접 부호화 시스템Direct Encoding System of Composite Video Signal

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제2도는 본 발명에 따른 복합 영상 신호의 직접 부호화 시스템 구성도.2 is a block diagram of a direct encoding system of a composite video signal according to the present invention.

Claims (1)

칼라 복합 영상 신호를 대역 압축 전송하는 예측 부호화 장치에 있어서, 복합 영상 신호 입력단(13)의 디지탈 신호는 감산기(14)에서 예측된 디지탈 신호와 감산되어 그 차이치만을 양자기(15)에 인가시키고, 양자기(15)의 출력은 전송 출력단(23)으로 출력되며 동시에 가산기(18)와 라인메모리(17) 및 가산기(15)를 순차거쳐 감산기(2)와 가산기(18)에 각각 인가되도록 구성하고, 상기 가산기(18)의 출력과 라인메모리(17)의 출력이 쉬프트 레지스터(20)에 인가하도록 구성하고, 쉬프트레지스터(20)의 출력은 가산기(21)를 거쳐 가산기(15)에 인가하도록 구성한 것을 특징으로 하는 복합 영상 신호의 직접 부호화 시스템.In the prediction encoding apparatus for band compression transmission of a color composite video signal, the digital signal of the composite video signal input terminal 13 is subtracted from the digital signal predicted by the subtractor 14 to apply only the difference value to the quantizer 15. The output of the quantizer 15 is output to the transmission output terminal 23, and is configured to be applied to the subtractor 2 and the adder 18 by sequentially passing through the adder 18, the line memory 17 and the adder 15, respectively. The output of the adder 18 and the output of the line memory 17 are applied to the shift register 20, and the output of the shift register 20 is applied to the adder 15 via the adder 21. A direct encoding system of a composite video signal, characterized in that the configuration. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
