SYNCHRONIZATION DEVICE AND RADIO TRANSMISSION SYSTEM |
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,...). |
