Abstract

UN RECEPTOR DE TELEVISION DE IMAGENES INCLUIDAS DENTRO DE OTRAS VISUALIZA UNA IMAGEN COMPUESTA, QUE INCLUYE UNA IMAGEN COMPRIMIDA OBTENIDA DE UNA ENTRADA DE SEÑAL AUXILIAR DE UNA IMAGEN COMPLETA OBTENIDA A PARTIR DE UNA SEÑAL PRINCIPAL. LA SEÑAL DE VIDEO COMPUESTA AUXILIAR SE MUESTREA (124, 126) SINCRONAMENTE CON UNA SEÑAL DE RELOJ DEL SISTEMA ENGANCHADA POR IMPULSOS A SEÑAL PRINCIPAL. LA SEÑAL DE DATOS MUESTREADA SE SEPARA (128) EN SEÑALES COMPONENTES DE INFORMACION E LUMINANCIA Y COLOR, QUE S SUBMUESTREAN (130) Y SE ALMACENAN EN UNA MEMORIA DE CAMPO (136) SINCRONA CON LA SEÑAL DE RELOJ DEL SISTEMA. LA FASE DE LA SEÑAL DE RELOJ UTILIZADA PARA EL SUBMUESTREO HORIZONTAL SE DETERMINA AL COMIENZO DE CADA LINEA, PARA COMPENSAR ERRORES DE DESLIZAMIENTO DE LA SEÑAL AUXILIAR. LAS MUESTRAS DE LUMINANCIA RECUPERADAS DE LA MEMORIA SE APLICAN A LA CIRCUITERIA DE TRANSFERENCIA DE RELOJ (146), QUE RESINCRONIZA LAS MUESTRAS A UNA VERSION CON DESVIACION DE FASE DE LA SEÑAL DEL RELOJ DEL SISTEMA, PARA COMPENSAR ERRORES DE DESLIZAMIENTO DE LA SEÑAL PRINCIPAL. LA SEÑAL DE RELOJ DESVIADA EN FASE (142) SE SINCRONIZA CON LAS SEÑALES DE EXPLORACION HORIZONTAL UTILIZADAS PARA VISUALIZAR LA IMAGEN COMPUESTA. LAS SEÑALES DE COMPONENTE DE INFORMACION DE COLOR (150) NO SE RESINCROZAN CON LA SEÑAL DE RELOJ DESVIADA EN FASE. LAS SEÑALES COMPONENTES DE LA IMAGEN COMPRIMIDA SE COMBINAN (154) PARA FORMAR UNA SEÑAL COMPUESTA QUE TENGA INFORMACION DE COLOR QUE SE SINCRONICE CON LA SEÑAL PRINCIPAL. LA SEÑAL COMPRIMIDA SE SUSTITUYE (114) POR UNA PARTE DE LA SEÑAL PRINCIPAL, PARA GENERAR UNA SEÑAL QUE REPRESENTE LA IMAGEN COMPUESTA.
