Abstract

UNA SEÑAL (24) DE VIDEO SECUNDARIA ES MUESTREADA, DIGITALIZADA Y COMBINADA CON UNA SEÑAL (SS) DE CONMUTACION EN MEMORIA. LA SEÑAL DIGITAL MIXTA SE ALMACENA EN UNA MEMORIA (900) DE VIDEO DE ACCESO ALEATORIO. LA SEÑAL ALMACENADA SE LEE EN SINCRONISMO CON LAS COMPONENTES DE SEÑAL DE SINCRONISMO DE UNA SEÑAL DE VIDEO PRIMARIA. LA SEÑAL DE CONMUTACION SE RECUPERA DE LA SALIDA DE LA MEMORIA, Y SE COMPARA CON UNA SEÑAL (CSS) DEL CODIGO DE CONTEXTO PARA GENERAR UNA SEÑAL (FSS) DE CONMUTACION RAPIDA. UN CONMUTADOR (80) DE VIDEO, ACOPLADO PARA RECIBIR LA SEÑAL DE VIDEO PRIMARIA Y LA SEÑAL DE VIDEO SECUNDARIA ALMACENADA Y QUE RESPONDE A LA SEÑAL DE CONMUTACION RAPIDA, APLICADA UNA SEÑAL ADECUADA DE LAS DOS SEÑALES DE ENTRADA AL CINESCOPIO (94) PARA DEFINIR UNA IMAGEN INSERTADA SECUNDARIA DENTRO DE UNA IMAGEN PRIMARIA GRANDE.
