    • A system and method for supporting mobile Internet communication is provided which employs a plurality of Routers and a plurality of Mobile Nodes (MNs). Each Router has a unique communication address. Each MN is associated with a home Router. Each Router has an associated Mobile Node Location List identifying each MN for which the Router is the home Router and the communication address of a Router corresponding to a current location of each such MN. Each MN is movable from an old location where the MN communicates with the Internet via one Router to a current location where the MN communicates with the Internet via a different Router. Communication at the current location via the different Router is established by communicating to the MN's home Router the communication address of the different Router as the communication address corresponding to the MN's current location. Accordingly, a data communication from a corresponding node (CN) to a selected MN is communicated to the selected MN by accessing the Mobile Node Location List of the selected MN's home Router to determine the communication address corresponding to the selected MN's current location and directing the data communication to that determined communication address.
    • 提供一种用于支持移动因特网通信的系统和方法,其采用多个路由器和多个移动节点(MN)。 每个路由器都有一个独特的通讯地址。 每个MN与归属路由器相关联。 每个路由器具有相关联的移动节点位置列表,其标识路由器是家庭路由器的每个MN,以及对应于每个这样的MN的当前位置的路由器的通信地址。 每个MN可以从MN通过一个路由器与因特网通信的旧位置移动到MN通过不同路由器与因特网通信的当前位置。 通过与MN的归属路由器通信,将不同路由器的通信地址作为与MN当前位置对应的通信地址进行通信,建立通过不同路由器在当前位置的通信。 因此,通过访问所选MN的归属路由器的移动节点位置列表来确定与所选择的MN的当前位置相对应的通信地址,并将所指示的MN的当前位置的通信地址指向 数据通信到确定的通信地址。

    • Signals encoded with watermark information are generated and broadcast into a protected area for capture by illicit recording devices along with their intended targets. An illicit recording in which at least a portion of the broadcast watermark signals are recorded is obtained and correlated with a known position of the broadcast watermark signals to yield the location of illicit recording devices. In an alternate embodiment, a surveillance device, being image and time synchronized with a signal broadcasting device, monitors and records the protected area. Illicit recordings containing the broadcast watermark are obtained and correlated with corresponding recordings taken by the surveillance device to identify the location of illicit recording devices. In an alternate embodiment, the surveillance device further monitors the quality of the broadcast watermark signals and adjusts them accordingly to achieve a desired quality level.
    • 生成用水印信息编码的信号,并将其广播到被保护的区域,以供非法记录装置与其预期目标一起捕获。 获得其中记录了广播水印信号的至少一部分的非法记录,并与广播水印信号的已知位置相关联,以产生非法记录装置的位置。 在替代实施例中,与信号广播设备同时进行图像和时间同步的监视设备监视和记录保护区域。 获得包含广播水印的非法记录,并与监视设备拍摄的相应记录相关联,以识别非法记录设备的位置。 在替代实施例中,监视装置还监视广播水印信号的质量并相应地调整它们以实现期望的质量水平。
