    摘要： 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 (1) which wireless-transmits an AV content; and a plurality of wireless sink devices (5, 6) which reproduce the wireless-transmitted AV content. The bridge device (1) has a group identification table which stores a group identifier for identifying a group formed by the wireless sink device (5, 6). The bridge device (1) adds a group identifier extracted from the group identification table to a control command for controlling the sink devices (5, 6) and wireless-transmits the control command having the group identifier. The wireless sink devices (5, 6) receive a control command wireless-transmitted from the bridge device (1) if a corresponding group identifier is added to the control command.

    摘要： When reproducing AV data transmitted from a source device by multicast wireless transmission, a sink device can check the wireless connection status of other sink device which reproduces AV data from the same source device. The sink device (2a) includes: an AV reception portion which receives AV data through multicast wireless transmission from the source device (1); a reproduction portion which extracts and reproduces AV data transmitted to the sink device (2a) from the received AV data; and a device information receiving portion that wirelessly receives a portion or whole of the sink device information managed in the source device (1). The sink device information correlates identification information for identifying a plurality of sink devices (2a, 2b, . . . ) containing the sink device (2a) with state information indicative of wireless connection status of the sink devices (2a, 2b, . . . ).
