WIRELESS COMMUNICATION SYSTEM

PROBLEM TO BE SOLVED: To provide a wireless communication system, where a center device and a master device are wire-connected and the master device wirelessly transmits video and audio to a slave device, which prevents video and audio from being disturbed at a terminal even when a radio wave state changes. SOLUTION: The master device 120 discriminates the state of a radio wave with the slave device 140 depending on a reception level or signal check sum of the slave or master device. Then the master device decides the transmission rate depending on the state of radio wave and informs the slave device 140 and a center device 100 about it. The center device 100 transmits data at a coding rate corresponding to it. The slave device 140 receives the signal depending on the rate to transmit the signal at the rate depending on the state of radio wave.
