Abstract
In a wireless audio system in which both wireless audio signal transmission and communication using other wireless apparatuses are carried out, the transmitter and the receiver transmit audio packets by the following procedure using a plurality of communication channels shared with other wireless communication. The transmitter and the receiver select the same channel; after detecting that the channel has become idle, the transmitter stands by for only a stand-by time Tshorter than the shortest packet space stipulated in the procedure of the other wireless communication and then transmits an audio packet; after the reception of the audio packet is completed, the receiver stands by for only a stand-by time Tshorter than the shortest packet space and then returns a response signal. After the transmission/reception of a predetermined number of audio packets is completed, the transmitter and the receiver switch the communication channel and repeat the procedure.
