摘要：
描述用于使能分块内容的客户机控制的流送的方法及系统，其中所述客户机控制的流送以清单文件为基础，所述清单文件包括一个或多个分块标识符以及一个或多个关联的分块定位符，所述分块定位符优选为一个或多个URL，用于定位配置成向所述客户机传递一个或多个分块的一个或多个传递节点，所述分块由所述分块标识符识别，并且其中所述方法包括：以从所述清单文件中选出的至少一个分块标识符为基础请求至少一个分块的传递；以所述所请求的分块为基础，从所述清单文件中选择至少一个另外的分块标识符，所述另外的分块标识符与期望的未来分块请求关联；以及，预解析与所述所选的另外的分块标识符关联的第一分块定位符以获得与所述第一分块定位符关联的网络信息。
摘要（英）：

Methods and systems for enabling client-controlled streaming of segmented content are described. In one example, the client-controlled streaming is on the basis of a manifest file, the manifest file including one or more segment identifiers and one or more associated segment locators, In one example, a method involves: requesting the delivery of at least one segment on the basis of a first segment identifier selected from the manifest file; on the basis of the first requested segment, selecting a second at least one segment identifier from the manifest file, the second segment identifier being associated with an expected future segment request; and pre-resolving a first segment locator associated with the selected second segment identifier for obtaining network information associated with the first segment locator.
