Abstract

UN DECODIFICADOR DE INFORMACION DE VIDEO AUXILIAR PARA EXTRAER UNA SEÑAL DE INFORMACION DE VIDEO AUXILIAR DESDE UNA SEÑAL DE VIDEO INCLUYE UN AMPLIFICADOR DE DATOS (230) Y UN APARATO (220) PARA AJUSTAR EL NIVEL DE DESVIACION DEL AMPLIFICADOR DE DATOS (230). EL NIVEL DE DESVIACION SE AJUSTA RAPIDAMENTE HASTA SE DETECTA QUE UN COMPONENTE DE REFERENCIA DE LA SEÑAL DE INFORMACION AUXILIAR DURANTE UN INTERVALO DE REPRESENTACION DE LA SEÑAL DE VIDEO EN EL QUE LA INFORMACION DE VIDEO AUXILIAR SE ESPERA QUE OCURRA. SE INCREMENTA UNA CUENTA DESPUES DE LOS INTERVALOS DE REPRESENTACION EN LOS QUE EL COMPONENTE DE REFERENCIA SE DETECTA Y SE RESTA DESPUES DEL INTERVALO DE REPRESENTACION EN EL QUE NO SE DETECTA EL COMPONENTE DE REFERENCIA. EL AJUSTE DE NIVEL DE DESVIACION CESA MIENTRAS LA CUENTA ES AL MENOS UN NUMERO PREDETERMINADO. EL APARATO SE ADAPTA RAPIDAMENTE AL NIVEL DE DESVIACION PARA LOS CAMBIOS DE AMPLITUD DE SEÑAL DE VIDEO A LARGO PLAZO O DE UNA MAGNITUD SIGNIFICANTE (V.G. SIGUIENDO UN CAMBIODE CANAL) Y MANTIENE UN NIVEL DE DESVIACION CONSTANTE CUANDO OCURREN VARIACIONES TRANSITORIAS EN LA AMPLITUD DE SEÑALES DE VIDEO.
