Abstract
A wireless transmission system is provided that can minimize the control command transmission amount by operating a plurality of sink devices in conjunction with each other with respect to each group when performing a wireless AV transmission. The wireless transmission system includes: a bridge device () which wireless-transmits an AV content; and a plurality of wireless sink devices () which reproduce the wireless-transmitted AV content. The bridge device () has a group identification table which stores a group identifier for identifying a group formed by the wireless sink device (). The bridge device () adds a group identifier extracted from the group identification table to a control command for controlling the sink devices () and wireless-transmits the control command having the group identifier. The wireless sink devices () receive a control command wireless-transmitted from the bridge device () if a corresponding group identifier is added to the control command.
