PROBLEM TO BE SOLVED: To provide a wireless LAN network system in which leakage of data distribution is suppressed when the network groups by ad hoc mode and infrastructure mode are mixed.SOLUTION: When a karaoke device 12 set as a leader in a network group by infrastructure mode is included, at the same time, in a network group by ad hoc mode, top broadcast for the network group by infrastructure mode is performed from the karaoke device 12, and top broadcast for the network group by ad hoc mode is also performed. Consequently, for an electronic quick reference device 14, not associated with any karaoke device 12 included in the network group by infrastructure mode, data can be distributed suitably from a karaoke device 12 set as a leader. |
