Fecha de publicación: 15/06/2006 Fuente: Wipo "digitalization" A method (30) of digital remodulation of a received or source signal using a digital audio radio (116) having a first digital radio frequency path (119 to 116) or using a first digital radio frequency comprises the steps of re-encoding (38) the received signal to provide a re-encoded digital signal, reformatting (40) the re-encoded digital signal into a new digital format signal, and digitally modulating (42) a radio frequency carrier with the new digital format signal. The method further comprises the step of selectively switching (42) a radio frequency path of the digital audio radio from the first digital radio frequency path to a second radio frequency path (114 to 116) or from the first digital radio frequency to a second digital radio frequency having the radio frequency carrier with the new digital format signal.
