The sink device () includes: an AV reception portion which receives AV data through multicast wireless transmission from the source device (); a reproduction portion which extracts and reproduces AV data transmitted to the sink device () 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 (). The sink device information correlates identification information for identifying a plurality of sink devices (, . . . ) containing the sink device () with state information indicative of wireless connection status of the sink devices (, . . . ).
