    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: It is an object to provide a broadcast receiving device capable of shortening the time from turning-on until display of an IP broadcast. A broadcast receiving device 1, after its start-up, automatically performs setting related to an Internet protocol (IP) including setting of an address of a DNS server and receives an IP broadcast of a specified channel by multicast communication, wherein the broadcast receiving device starts to receive the IP broadcast from an IP broadcast server 53a through an IP network 4 by specifying a multicast address corresponding to the specified channel that is stored beforehand, before completion of the setting of the address of the DNS server.

    摘要: Disclosed are a wireless transmission system and a wireless transmission method that prevent CEC protocols from being affected by wireless communication transmission delays or buffering delays and failing when CEC communication is performed wirelessly in the HDMI standard. The CEC control unit of a first wireless communication device (illustrated with a receiver (3)) exchanges CEC messages with the CEC control unit provided for a display device (illustrated with a monitor (4)) using a logical address corresponding to the device type of the AV device (illustrated with STB (1)). The CEC control unit of a second wireless communication device (illustrated with a transmitter (2)) exchanges CEC messages with the CEC control unit provided for STB (1) using a logical address corresponding to the device type of the monitor (4).

    摘要: Disclosed is a wireless transmission system provided with: a sink device which, when AV data transmitted by means of multicast wireless transmission from a source device is reproduced, performs reproduction control in accordance with the wireless connection state of another sink device that reproduces the AV data from the same source device; and the source device which is capable of determining the wireless connection state and the reproduction control state of the sink device. When the AV data obtained by means of multicast wireless transmission from the source device (1) is reproduced, the sink device (2a) acquires state information indicating the wireless connection state of the other sink device and adjusts reproduction control for the AV data of the actual sink device (2a) in accordance with this state information. The source device (1) acquires information on the wireless connection state and the reproduction control state of each sink device and stops or restarts transmission of the AV data on the basis of this information.
