Abstract
UN APARATO DE COMPRESION DE SEÑALE DE VIDEO SUMINISTRA UN MEDIO PARA GENERAR RESIDUOS (12,16,17,18,14) QUE REPRESENTAN UN VALOR DE PIXEL QUE DIFERENCIA ENTRE VALORES DE PIXEL PREVISTOS Y REALES DE UN CUADRO DE CORRIENTE DE UNA SEÑAL DE VIDEO. LA CIRCUITERIA DE REDUCCION DE RUIDO, EN LA FORMA DE UN MEDIO DE PROCESAMIENTO NO LINEAL (500), ATENUA LOS RESIDUOS DE AMPLITUD INFERIOR MAS QUE LOS RESIDUOS DE AMPLITUD SUPERIOR Y ES SENSIBLE A UNA ESTIMACION DE RUIDO (1333). LOS RESIDUOS PROCESADOS SON TRANSFORMADOS (15) PARA SUMINISTRAR UNA SALIDA DE DATOS DE VIDEO COMPRIMIDA. SE REVELAN FUNCIONES DE PROCESAMIENTO NO LINEAL QUE ATENUAN EL RUIDO Y REDUCEN LA DISTORSION DE IMAGENES.
