Abstract
Aun cuando los parámetros de las senales de transferencia difieran entre los canales, se proporciona un aparato retransmisor para la senal de radiodifusion terrestre digital, el cual puede absorber la diferencia, y de manera estable puede retransmitir sin degradar las características de recepcion. En el aparato retransmisor 1 para la senal de radiodifusion terrestre digital, una unidad receptora 200 recibe las senales OFDM de las emisiones de television terrestre digital que se asignan a una pluralidad de canales, y selecciona un segmento, cuyo numero de segmento es 0, de cada una de las senales OFDM para generar las senales TS. Una unidad de multiplexacion-transferencia TS 300-1 multiplexa cada senal TS a una senal de corriente multiplexada, y una unidad de multiplexacion-transfereneia TS 300-2 separa la corriente multiplexada a las senales TS originales. Una unidad transmisora 400 combina las senales TS separadas de cada segmento, nuevamente segun un parámetro de senal de transferencia unificado, y transmite las senales combinadas como la senal que se habrá de retransmitir con una banda de frecuencias de un canal no utilizado.
