Abstract
A wireless multi-channel audio transmission method and a wireless multi-channel audio transmission device are disclosed in the present invention. The wireless multi-channel audio transmission method comprises: dividing the N channels of audio data into M groups of subset channel audio data, wherein each group of subset channel audio data comprises at least one channel of audio data; and transmitting the M groups of subset channel audio data to the M subset channel audio receiving devices through M transmission modules in parallel, wherein each of the transmission modules adopts a different transmitting frequency at the same time, and the transmission modules used for transmitting each group of subset channel audio data are changed according to a preset changing rule. Thus, frequency division multiplexing and spatial diversity are used to improve transmission bandwidth, reduce transmission delay and increase transmission reliability of wireless multi-channel audio transmission.
