<P>PROBLEM TO BE SOLVED: To provide a radio transmission method for an audio signal which uses radio communication and implements transmission of the audio signal with less possibility of a sound break. <P>SOLUTION: A radio transmission method for an audio signal comprises the steps of: selecting a primary and secondary channels from communication channels of a communication channel group having 3 or more channels; performing transmission of the audio signal by using both channels reciprocally; measuring transmission error rates of both channels while performing transmission of the audio signal and comparing the error rates of both channels; and, when the comparison result shows that the error rate of the primary channel is larger than that of the secondary channel, selecting the current secondary channel as a new primary channel, selecting a new secondary channel from the communication channels of the communication channel group and continuing the transmission of the audio signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
