Abstract

Se proporciona un aparato de rerradiación para difusión digital terrestre que puede continuar rerradiando una señal de difusión aún cuando el estado de recepción de la señal de difusión de deteriore intermitentemente con el movimiento. El aparato de rerradiación para la difusión digital terrestre incluye una pluralidad de antenas que se proporcionan en forma mutuamente espaciada a lo largo de la dirección de movimiento de un móvil, una pluralidad de partes de procesamiento de recepción provistas correspondientes a cada antena, una parte de selección amestra que selecciona cualquiera de las partes de procesamiento de recepción como un maestro, una parte de supervisión que supervisa recibir estados de las señales de difusión digital terrestre de la pluralidad de partes de procesamiento de recepción, una parte de conmutación, y una unidad de rerradiación. La parte de conmutación selecciona la señal de difusión digital terrestre recibida por la parte de procesamiento de recepción seleccionada como maestra o la señal de difusión digital terrestre recibida por otra parte de procesamiento de recepción basada en el estado de recepción de la parte de procesamiento de recepción seleccionada como maestra, y la unidad de rerradiación rerradia la señal de difusión digital terrestre seleccionada en el móvil.
