Abstract

GENERADOR DE SEÑAL VIDEO IMAGEN-EN-IMAGEN QUE INCLUYE UNA FUENTE (50) DE UNA SEÑAL DE VIDEO AUXILIAR Y UN PRODUCTOR (60) DE MUESTRAS SUCESIVAS QUE REPRESENTAN LA SEÑAL DE VIDEO AUXILIAR. UNA MEMORIA AUTOSECUENCIADA (70) INCLUYE UNA TERMINAL DE ENTRADA DE DATOS ACOPLADA AL PRODUCTOR DE MUESTRAS DE VIDEO AUXILIAR. UNA TERMINAL DE ENTRADA DE DIRECCION DE ESCRITURA RECIBE UNA DIRECCION DE ESCRITURA INICIAL; EXISTEN IGUALMENTE UNA TERMINAL DE SALIDA DE DATOS Y UNA TERMINAL DE ENTRADA DE DIRECCION DE LECTURA PARA RECIBIR UNA DIRECCION INICIAL DE LECTURA. UN CIRCUITO DE CONTROL DE ESCRITURA (80.90) VA ACOPLADO A LA TERMINAL DE DIRECCION DE ESCRITURA DE LA MEMORIA AUTOSECUENCIADA Y GENERA DIRECCIONES INICIALES DE ESCRITURA SINCRONIZADAS CON INTERVALOS DE LINEA HORIZONTAL DE LA SEÑAL DE VIDEO AUXILIAR. TAMBIEN VA INCORPORADA UNA FUENTE (10) DE UNA SEÑAL PRINCIPAL DE VIDEO. UN CIRCUITO DE CONTROL DE LECTURA (100,110) VA ACOPLADO A LA TERMINAL DE DIRECCION DE LECTURA DE LA MEMORIA AUTOSECUENCIADA Y GENERA DIRECCIONES INICIALES DE LECTURA SINCRONIZADAS CON INTERVALOS DE LINEA HORIZONTAL DE LA SEÑAL PRINCIPAL DE VIDEO. EXISTEN MEDIOS (20,30) PARA COMBINAR LA SEÑAL DE VIDEO PRINCIPAL CON MUESTRAS DE LA MEMORIA AUTOSECUENCIADA PARA FORMAR UNA SEÑAL DE VIDEO QUE REPRESENTA UNA IMAGEN DEL TIPO IMAGEN-EN-IMAGEN.
