Abstract: The present invention relates to a device and a method for performing channel selection in a wireless AV system. Such present specification discloses a wireless data transmission device for performing channel selection, the device comprising: a communication unit for performing the steps of selecting an initial channel in a non-connection state on the basis of first channel monitoring, transmitting a periodic beacon onto the initial channel in a standby mode after switching to a connection state, and selecting a new channel in the standby mode on the basis of second channel monitoring in an interval in which beacon transmission does not occur; and a processor connected to the communication unit so as to control the operation of the communication unit. Fast and economic channel selection appropriate for the wireless AV system is possible.
