Abstract

UN FILTRO DIGITAL (20,30) SEPARA UNA COMPONENTE DE CROMINANCIA (C12) DE M-BITS (12) DE UNA SEÑAL DE VIDEO COMPUESTA DIGITAL (CV) DE N-BITS (8) SUMINISTRADA AL MISMO, M(12) SIENDO SUPERIOR A N(8) DEBIDO A LAS OPERACIONES ARITMETICAS (24,44,46,50) REQUERIDAS PARA LA SEPARACION. EL COMPONENTE DE CROMINANCIA DE M BITS SEPARADO ES REDUCIDO A N-BITS Y SUBSTRAIDO DE LA SEÑAL DE VIDEO COMPUESTA PARA SUMINISTRAR UNA COMPONENTE DE LUMINANCIA SEPARADA. PARA LA REDUCCION DE BITS, EL COMPONENTE DE CROMINANCIA SEPARADA (C12) ESTA SUJETO AL REDONDEO SIMETRICO (100A O 100B Y 104) Y A LA LIMITACION (104). VENTAJOSAMENTE, EL REDONDEO SIMETRICO DEL COMPONENTE DE CROMINANCIA SUMINISTRA REDUCE UNA TENDENCIA DEL COMPONENTE DE LUMINANCIA A MOSTRAR EL CONTORNO CUANDO SE VISUALIZA.
