Abstract

UN PREPROCESADOR PARA ADAPTAR SEÑALES DE VIDEO DE EXPLORACION DE ENTRELAZAMIENTO PARA COMPRESION BASADA DE CUADRO, INCLUYE APARATO (40) PARA ACEPTAR CAMPOS DE VIDEO EXPLORADO DE ENTRELAZAMIENTO Y PROPORCIONAR CAMPOS DE LUMINANCIA EXPLORADA DE ENTRELAZAMIENTO Y SEÑALES DE COMPONENTES DE CROMINANCIA. LOS CAMPOS DE COMPONENTES DE LUMINANCIA EXPLORADOS DE ENTRELAZAMIENTO SE COMBINAN (45) EN RESPECTIVOS CUADROS DE SEÑAL DE LUMINANCIA Y SE APLICAN A APARATOS COMPRESORES PARA POSTERIOR PROCESAMIENTO. LOS CAMPOS DE COMPONENTES DE CROMINANCIA EXPLORADA DE ENTRELAZAMIENTO SE PROCESAN INDEPENDIENTEMENTE (41, 42) EN EL NIVEL DE CAMPO, PARA GENERAR LINEAS DE VALORES DE CROMINANCIA, QUE SON INTERSTICIALES A LAS LINEAS DE LOS VALORES DE CROMINANCIA ORIGINALES, Y EN DENSIDAD DE LINEAS Y PIXEL MENORES. LOS CAMPOS INDEPENDIENTEMENTE PROCESADOS DE SEÑALES DE CROMINANCIA EXPLORADA DE ENTRELAZAMIENTO SE COMBINAN (43, 44) EN RESPECTIVOS CUADROS DE SEÑALES DE COMPONENTES DE CROMINANCIA Y SE APLICAN A LA CIRCUITERIA (46) DEL COMPRESOR PARA POSTERIOR PROCESAMIENTO. EJECUTANDO LA INTERPOLACION DE SEÑALES DE CROMINANCIA Y EL SUBMUESTREO (41, 42) EN LOS NIVELES DE CAMPO, SE TIENDE A ELIMINAR LA MAYOR PARTE DE LAS DISTORSIONES DE COLORES ALREDEDOR DE IMAGENES EN MOVIMIENTO. EL APARATO RECEPTOR (50) SE CONFIGURA PARA EJECUTAR PROCESAMIENTO POSTERIOR A LA DESCOMPRESION, PARA GENERAR DATOS DE CUADRO QUE TIENEN LA DENSIDAD DE LINEAS Y PIXEL ORIGINALES.
