    Abstract: A system, apparatus and method are described for improving marker identification within a motion capture system. For example, a system according to one embodiment of the invention comprises: a plurality of cameras configurable for a motion capture session, each of the cameras having an illuminating device for generating light and a lens for capturing light reflected off of one or more retro-reflective markers used for the motion capture session; and a plurality of pieces of polarized material coupled over the illuminating device and the lens of each of the cameras, wherein for each individual camera, either a first orientation or a second orientation for the polarized material is selected based on which other cameras are within the individual camera's field of view and the orientation of the polarized material used for the other cameras, the first orientation being perpendicular to the second orientation.

    Abstract: A network for wireless transmission of a media data in a building includes a plurality of access points. A first access point receives the media data from a source and transmits the media data downstream at a first data rate. A plurality of additional access points is distributed about the building, each of which includes an upstream transceiver to receive the media content on a first channel and a downstream transceiver to re-transmit the media content at substantially the first data rate on a second channel. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

    Abstract translation: 用于建筑物中的媒体数据的无线传输的网络包括多个接入点。 第一接入点从源接收媒体数据,并以第一数据速率向下游发送媒体数据。 关于建筑物分布有多个附加接入点,每个附加接入点包括上行收发器以在第一信道上接收媒体内容和下游收发信机,以基本上在第二信道上的第一数据速率重新发送媒体内容。 要强调的是,该摘要被提供以符合要求抽象的规则,允许搜索者或其他读者快速确定技术公开内容的主题。 提交它的理解是,它不会用于解释或限制权利要求的范围或含义。
