Abstract

Se describe un codificador de audio digital, un acondicionador de video digital y un modulador digital para la produccion de una senal de radiodifusion de television en un intervalo deseado de frecuencia de canal. Las senales de canal de audio izquierdo y derecho son digitalizadas y codificadas de acuerdo con un estandar de estereo y posteriormente, son combinadas para formar una senal de audio de estereo. Una segunda senal de canal de programacion de audio podria ser incluida. Una entrada de video puede ser digitalizada y acondicionada para formar un canal digital de video. La senal de audio de estereo puede ser directamente colocada en la frecuencia deseada de canal mediante una modulacion de frecuencia sin la necesidad de utilizar una frecuencia intermedia. El canal digital de video puede ser colocado en la frecuencia deseada mediante la modulacion de amplitud. Los canales digital y de audio pueden ser combinados en forma digital para crear una senal de transmision de television a una frecuencia deseada y de acuerdo con un estandar deseado.
