    Abstract: In one embodiment, a client device queries a location server using a client-selected interface for content retrieval from a content distribution network (CDN), and receives a location attribute from the location server based on a location of the client device. The client device then presents the location attribute to a CDN selector within a first content retrieval request, and may receive a redirection from the CDN selector to a selected content source based on the location attribute. As such, the client device may then initiate a second content retrieval request to the selected content source. In another embodiment, a CDN selector receives a content retrieval request from a client device, and determines that the content retrieval request contains a location attribute indicating a location of the client device. Based on the location attribute, the CDN selector selects a content source, and redirects the client device to the selected content source.

    Abstract translation: 在一个实施例中，客户端设备使用客户端选择的接口从内容分发网络（CDN）查询内容检索的位置服务器，并且基于客户端设备的位置从位置服务器接收位置属性。 然后，客户端设备将位置属性呈现给第一内容检索请求内的CDN选择器，并且可以基于位置属性从CDN选择器接收到所选内容源的重定向。 这样，客户端设备然后可以向所选择的内容源发起第二内容检索请求。 在另一个实施例中，CDN选择器从客户端设备接收内容检索请求，并确定内容检索请求包含指示客户端设备的位置的位置属性。 基于location属性，CDN选择器选择内容源，并将客户端设备重定向到所选择的内容源。

    Abstract: Consistent with embodiments of the present invention, a system may be provided to provide per-subscriber stream management comprising: a client capable of receiving a playlist containing a subset of segments associated with a video asset; a video application server to request subscriber state information and to build state representations in a subscriber database on a per-subscriber basis; a media segmenter capable of providing the video asset in multiple bit rates; a subscriber state manager capable of managing the current state of one or more subscribers in a subscriber database; and a stream manager capable of requesting the assignment of bandwidth from a wireless infrastructure on a per-subscriber basis.
