Abstract

UN SISTEMA DE REGISTRO DE SEÑALES DE VIDEO MEJORADO PARA EL REGISTRO DE UNA SEÑAL DE VIDEO DE ANCHO DE BANDA LLENO EN UN SOPORTE DE ANCHO DE BANDA LIMITADO QUE INCLUYE UN CODIFICADOR 10, ACOPLADO A UN TERMINAL DE ENTRADA 5, PARA PROCESAR DE FORMA ADAPTABLE UNA SEÑAL DE VIDEO COMPUESTA EN RESPUESTA A UNA SEÑAL REPRESENTATIVA DE UN MOVIMIENTO Y GENERAR DOS SEÑALES; UNA SEÑAL DE LUMINANCIA L{SUB,F}, EN LA QUE SE SUBMUESTREAN LAS ALTAS FRECUENCIAS ATENUADAS PARA ASI PLEGARLAS Y METERLAS EN UN AGUJERO ESPECTRAL DE LA GAMA DE BAJAS FRECUENCIAS, Y LIMITAR EL ANCHO DE BANDA AL ANCHO DE BANDA LIMITADO DEL SOPORTE DE REGISTRO, Y UNA SEÑAL COMBINADA C+M{SUB,R} QUE INCLUYE UN COMPONENTE DE CROMINANCIA Y UNO DE MOVIMIENTO. EL CIRCUITO DE REGISTRO DE LA SEÑAL DE LUMINANCIA 20 REGISTRA LA SEÑAL DE LUMINANCIA PLEGADA EN EL SOPORTE, Y EL CIRCUITO DE REGISTRO DE SEÑALES DE CROMINANCIA REGISTRA LA SEÑAL DE CROMINANCIA Y MOVIMIENTO COMBINADA EN EL SOPORTE. TAMBIEN SE PRESENTA UN SISTEMA DE REPRODUCCION DE SEÑALES DE VIDEO MEJORADO PARA LA REPRODUCCION DE TAL SEÑAL DE VIDEO PREVIAMENTE REGISTRADA. EL SISTEMA DE REPRODUCCION CONSISTE EN UN CIRCUITO DE REPRODUCCION DE SEÑALES DE LUMINANCIA 60 PARA RECUPERAR DEL SOPORTE LA SEÑAL DE LUMINANCIA PREVIAMENTE REGISTRADA L{SUB,PB} Y UN CIRCUITO DE REPRODUCCION DE SEÑALES DE CROMINANCIA 80 PARA RECUPERAR DEL SOPORTE LAS SEÑAL DE CROMINANCIA Y MOVIMIENTO COMBINADA C+M. UN DECODIFICADOR 70 EXTRAE LA SEÑAL DE MOVIMIENTO Y LA SEÑAL DE CROMINANCIA DE LA SEÑAL DE CROMINANCIA Y MOVIMIENTO COMBINADA Y UN CIRCUITO DE DESPLIEGUE EXTRAE LAS ALTAS FRECUENCIAS DE LUMINANCIA DE LA SEÑAL DE LUMINANCIA PLEGADA PREVIAMENTE REGISTRADA Y REGENERA DE FORMA ADAPTABLE LA SEÑAL DE LUMINANCIA DE ANCHO DE BANDA LLENO EN RESPUESTA A LA SEÑAL DE MOVIMIENTO. ESTA SEÑAL DE LUMINANCIA DE ANCHO DE BANDA LLENO SE COMBINA CON LA SEÑAL DE CROMINANCIA PARA REPRODUCIR LA SEÑAL DE VIDEO COMPUESTA REGISTRADA EN UN PRINCIPIO. SE PUEDE REPRODUCIR UN MEDIO DE REGISTRO PREVIAMENTE REGISTRADO POR TAL SISTEMA DE REGISTRO EN UN SISTEMA DE REPRODUCCION ESTANDAR SIN QUE APAREZCAN ARTEFACTOS MOLESTOS EN LA IMAGEN REPRODUCIDA.
