    • A server may provide information describing characteristics of audio and video components to a client, separately from encoded samples of the audio and video components themselves. The client may use the information to select components, and then to request the selected components, e.g., in accordance with a streaming network protocol. In one example, an apparatus for sending encapsulated video data includes a processor configured to determine characteristics for components of a plurality of representations of video content, wherein the characteristics comprise at least one of a frame rate, a profile indicator, a level indicator, and dependencies between the components, and one or more interfaces configured to send the characteristics to a client device, receive a request from the client device for at least one of the components after sending the characteristics, and send the requested components to the client device in response to the request.
    • 服务器可以向音频和视频组件本身的编码样本分开地向客户端提供描述音频和视频组件的特征的信息。 客户端可以使用该信息来选择组件,然后例如根据流网络协议来请求所选择的组件。 在一个示例中,用于发送封装的视频数据的装置包括被配置为确定视频内容的多个表示的组件的特征的处理器,其中所述特征包括帧速率,简档指示符,级别指示符和 组件之间的依赖关系以及被配置为向客户端设备发送特性的一个或多个接口在发送特性之后从组件中的至少一个组件接收来自客户端设备的请求,并响应于所请求的组件发送给客户端设备 要求。

    • A method for determining a derived geographic location of a target Internet host includes identifying plural landmark Internet hosts communicatively coupled with the target Internet host by a network. The method also includes measuring network latencies of probe packets transmitted to the target and landmark Internet hosts along different network pathways and calculating relative distances between the target Internet host and one or more of the landmark Internet hosts based on the network latencies. The method further includes comparing the relative distances to identify at least one of the landmark Internet hosts that is geographically closer to the target Internet host than one or more other landmark Internet hosts and determining the derived geographic location of the target Internet host based on a geographic location of the at least one of the landmark Internet hosts that is geographically closer to the target Internet host.
    • 用于确定目标因特网主机的导出地理位置的方法包括通过网络识别与目标因特网主机通信耦合的多个地标性因特网主机。 该方法还包括测量根据不同网络路径传输到目标和地标Internet主机的探测包的网络延迟,并基于网络延迟计算目标Internet主机与一个或多个地标Internet主机之间的相对距离。 该方法还包括比较相对距离以识别与一个或多个其他地标性因特网主机在地理上更靠近目标因特网主机的地标性因特网主机中的至少一个,并且基于地理位置确定目标互联网主机的导出地理位置 地理位置上距离目标互联网主机更近的地标性互联网主机的位置。
