Abstract
Un sistema perfeccionado de recepción de televisión en color que utiliza corrección de altas inferidas multimodo para reducir infidelidades de color, qua comprende: medios de circuito para recibir una señal de televisión en color compuesta y para tratar a partir de ella una señal monócroma de banda ancha y una pluralidad de señales componentes de color de anchura de banda reducida; medios de circuito de corrección de altas inferidas multimodo para suplementar eficazmente cada señal componente de color a corregir en varios modos controlados por señales de funcionamiento que proporcionan componentes de señal inferidas de corrección que difieren en frecuencia o tiempo; medios de decisión de modo que responden a una pluralidad de componentes seleccionadas en dicha señal compuesta para producir una o más señales de control de modo que indican una necesidad inferida de corrección de altas inferidas en uno o más de dichos modos de funcionamiento controlados por señales; y medios de control de modoque responden operativamente a dicha señales de control de modo para habilitar o inhabilitar el funcionamiento de dicho circuito de corrección de altas inferidas multimodo en cada uno de sus varios modos de funcionamiento controlados por señales.
