Abstract

PROCESADOR DE VIDEO PARA UTILIZAR CON UNA PANTALLA. INCLUYE UN PRIMER RELOJ (FCS) QUE ESTA BLOQUEADO EN LINEA A LA PANTALLA (HSSD) Y UN SEGUNDO RELOJ (SCS) BLOQUEADO EN FASE AL COMPONENTE DE SINCRONIZACION HORIZONTAL (HSSS) DE UNA SEÑAL AUXILIAR DE VIDEO (YS,US,VS). UN CONVERTIDOR ANALOGICO DIGITAL (122), QUE REACCIONA AL SEGUNDO RELOJ, GENERA MUESTRAS DIGITALES REPRESENTATIVAS DE LA SEÑAL AUXILIAR DE VIDEO. UN CIRCUITO DE TRANSFERENCIA DE RELOJ (124), QUE REACCIONA A AMBOS RELOJES, CONVIERTE LAS MUESTRAS DIGITALES QUE TIENEN LUGAR SINCRONIZADAMENTE CON LA SEÑAL DEL SEGUNDO RELOJ A MUESTRAS DIGITALES QUE TIENEN LUGAR SINCRONIZADAMENTE CON LA SEÑAL DEL RELOJ BLOQUEADO EN LINEA. LAS MUESTRAS DIGITALES QUE OCURREN SIMULTANEAMENTE CON LA SEÑAL DE RELOJ BLOQUEADO EN LINEA SE ALMACENAN EN UNA MEMORIA (150).
