Abstract

UN METODO ELECTRONICO Y UN APARATO PARA CODIFICAR Y DECODIFICAR SEÑAL, PARA PROVEER REPRODUCCION DE SEÑALES ANALOGICAS CON ULTRA REDUCIDA DISTORSION, MIENTRAS QUE LOS RESTANTES APARATOS COMPATIBLES DE REPRODUCCION DE SEÑAL DE LA INDUSTRIA NORMALIZADA NO INCORPORAN LAS CARACTERISTICAS DE DECODIFICACION DE LA INVENCION, Y EN DONDE EL SISTEMA MEJORADO PROVEE UNA COMBINACION DE OPERACIONES DE GANANCIA, RAPIDEZ DE RESPUESTA Y SINTESIS DE ONDA PARA REDUCIR LAS DISTORSIONES DE SEÑAL Y MEJORAR LA RESOLUCION APARENTE, TODO BAJO EL CONTROL DE CODIGOS DE CONTROL OCULTOS PARA LA APROPIADA ACTIVACION DE COMPENSACION DE RECONSTRUCCION DE SEÑAL DECODIFICADA, QUE COMPLEMENTA EL ANALISIS DE SEÑAL HECHO DURANTE LA CODIFICACION. ADICIONALMENTE, PROCESOS DE CODIFICACION DE LAS SEÑALES DEFECTUOSAS CARACTERISTICOS DE LA INVENCION SON AMPLIAMENTE COMPATIBLES CON DECODIFICADORES DE REPRODUCCION LOS CUALES ESTAN INCORPORADOS A LA INVENCION, PARA PROVEER ALGUNAS MEJORAS GENERALES DE RESTAURACION.
