  • Publication number: 20130021531
    Abstract: 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.

  • Publication number: 20120011535
    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 (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.

  • Patent number: 6324188
    Abstract: An input voice signal is passed from a voice signal encoding unit to a voice signal compressing unit so that it is encoded and compressed. No transmission of a silence signal within the voice signal to a multiplexing unit is performed in a silence signal eliminating unit. A multiplexing unit multiplexes the voice signal with a data to be transmitted which has been passed via a data terminal control unit and a data terminal control unit from a data terminal and is transmitted to a communication line via the transmission control unit. Lapse of a time-out period of time which is present in a timer is detected in a silence signal inserting unit so that a silence signal is generated and is reproduced in a voice signal decompressing unit and a voice signal decoding unit.
