Abstract

UN SISTEMA MEJORADO DE GRABACION DE SEÑAL DE VIDEO PARA GRABAR UNA SEÑAL DE VIDEO DE BANDA ANCHA COMPLETA EN UN MEDIO DE BANDA ANCHA LIMITADA, INCLUYE UN CODIFICADOR 10, ACOPLADO A UN TERMINAL DE ENTRADA 5, PARA PROCESAR ADAPTABLEMENTE UNA SEÑAL DE VIDEO COMPUESTA EN RESPUESTA A UNA SEÑAL REPRESENTATIVA DEL MOVIMIENTO, Y PRODUCIR DOS SEÑALES; UNA SEÑAL DE LUMINANCIA LR, QUE TIENE FRECUENCIAS ALTAS ATENUADAS SUBMUESTREADAS PARA DOBLARSE EN UN HUECO ESPECTRAL EN LAS FRECUENCIAS BAJAS Y ES DE BANDA ANCHA LIMITADA HASTA LA ANCHURA DE BANDA LIMITADA DEL MEDIO DE GRABACION, Y UNA SEÑAL COMBINADA C+MR QUE INCLUYE UNA CROMINANCIA Y UN COMPONENTE DE MOVIMIENTO. EL CIRCUITO DE GRABACION DE LA SEÑAL DE LUMINANCIA 20 GRABA LA SEÑAL DE LUMINANCIA PLEGADA EN EL MEDIO, Y EL CIRCUITO DE GRABACION DE LA SEÑAL DE CROMINANCIA GRABA LA SEÑAL COMBINADA DE CROMINANCIA Y MOVIMIENTO EN EL MEDIO. TAMBIEN SE DESCRIBE UN SISTEMA MEJORADO PARA LA REPRODUCCION DE LA SEÑAL DE VIDEO PARA REPRODUCIR UNA SEÑAL DE VIDEO GRABADA CON ANTERIORIDAD. EL SISTEMA DE REPRODUCCION CONSISTE EN UN CIRCUITO DE REPRODUCCION DE LA SEÑAL DE LUMINANCIA 60 PARA RECUPERAR DEL MEDIO LA SEÑAL DE LUMINANCIA L SUB PB GRABADA CON ANTERIORIDAD, Y UN CIRCUITO DE REPRODUCCION DE SEÑAL DE CROMINANCIA 80 PARA RECUPERAR DEL MEDIO LA SEÑAL COMBINADA DE CROMINANCIA Y MOVIMIENTO C + M GRABADA CON ANTERIORIDAD. UN DESCODIFICADOR EXTRAE LA SEÑAL DE MOVIMIENTO Y LA SEÑAL DE CROMINANCIA DE LA SEÑAL COMBINADA DE CROMINANCIA Y MOVIMIENTO Y UN CIRCUITO DE DESPLIEGUE EXTRAE LAS FRECUENCIAS ALTAS DE LUMINANCIA DE LA SEÑAL DE LUMINANCIA PLEGADA GRABADA CON ANTERIORIDAD Y REGENERA ADAPTATIVAMENTE LA SEÑAL DE LUMINANCIA DE ANCHURA DE BANDA COMPLETA COMO RESPUESTA A LA SEÑAL DE MOVIMIENTO. ESTA SEÑAL DE LUMINANCIA REGENERADA CON ANCHURA DE BANDA COMPLETA SE COMBINA CON LA SEÑAL DE CROMINANCIA PARA REPRODUCIR LA SEÑAL DE VIDEO COMPUESTA GRABADA ORIGINALMENTE. UN MEDIO DE GRABACION GRABADO PREVIAMENTE MEDIANTE ESTE SISTEMA DE GRABACION PUEDE REPRODUCIRSEEN UN SISTEMA DE REPRODUCCION ESTANDAR SIN ARTEFACTOS MOLESTOS EN LA IMAGEN REPRODUCIDA.
