    Abstract: A method is provided in one example and includes receiving common format media including timed metadata associated with a timed metadata event. The method further includes extracting timed metadata information from the timed metadata, and generating a manifest corresponding to the common format media including the timed metadata information. The timed metadata information includes an indicator of a start time and an indicator of a duration of the timed metadata event. The method further includes generating a common format asset including the manifest.

    Abstract: A method is provided in one example and includes receiving media content including timed metadata, generating a common format asset including the timed metadata and a timed metadata index including at least one reference point corresponding to the common format asset. Each reference point includes state context information of the timed metadata at a particular instance of time. The method may further include receiving a request for the timed metadata from a particular client device, and retrieving a determined amount of the timed metadata from the common format asset using the timed metadata index. In a particular example, the determined amount of the timed metadata is an amount sufficient to display a current timed metadata context corresponding to the request.

    Abstract translation: 在一个示例中提供了一种方法，并且包括接收包括定时元数据的媒体内容，生成包括所述定时元数据的公共格式资产和包括对应于所述公共格式资产的至少一个参考点的定时元数据索引。 每个参考点包括在特定时间实例的定时元数据的状态上下文信息。 该方法还可以包括从特定客户端设备接收对定时元数据的请求，以及使用定时元数据索引从通用格式资产中检索确定量的定时元数据。 在特定示例中，确定的定时元数据量是足以显示与该请求相对应的当前定时元数据上下文的量。

    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中的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: A method is provided in one example embodiment and includes receiving a request for video content from a client device and accessing a common format representation for a requested chunk within the video content. The common format representation is provided in one or more files that include metadata indicative of one or more counters. The method can also include using the common format representation in conjunction with a deterministic equation to identify a predicted size of an output to be sent to the client device; and using the predicted size of the output to initiate transmitting at least a portion of a response to the client.
