WIRELESS CHANNEL SEARCHING METHOD, WIRELESS TRANSMITTING/RECEIVING SYSTEM, AND WIRELESS TRANSMITTING APPARATUS

摘要

A wireless channel searching method, a wireless transmitting/receiving system and a wireless transmitter are provided to rapidly switch a wireless transmission channel to another available channel when interference is generated in the wireless transmission channel. A wireless channel searching method includes a step of searching for unused wireless channels(S11), a step of storing a list of the searched unused wireless channels(S12), and a step of transmitting and receiving a multimedia signal through one of the unused wireless channels(S13). The wireless channel searching method further includes a step of comparing the transmission capacity of the multimedia signal with a predetermined reference level(S15), a step of updating the list of the unused wireless channels when the transmission capacity of the multimedia signal is lower than the reference level(S17), and a step of switching the wireless channel through which the multimedia signal is transmitted to one of the unused wireless channels when the wireless channel interferes with another wireless channel and transmitting/receiving the multimedia signal through the switched wireless channel(S27).
