    • In-program content targeting is described. A default data stream containing default content associated with multiple segments of a particular program is generated and transmitted. An alternate data stream containing alternate content for one or more of the multiple segments is also generated and transmitted. A client device receiving the default content via the default data stream detects the availability of alternate content via the data stream. Based on profile data associated with the client device (or a user of the client device) and profile data associated with the alternate content, the client device may access the alternate data stream for one or more segments of the particular program.
    • 描述了节目内容定位。 生成并发送包含与特定程序的多个段相关联的默认内容的默认数据流。 还生成并发送包含多个片段中的一个或多个的替代内容的备用数据流。 通过默认数据流接收默认内容的客户端设备通过数据流检测备用内容的可用性。 基于与客户端设备(或客户端设备的用户)相关联的简档数据和与备用内容相关联的简档数据,客户端设备可以访问特定程序的一个或多个段的备用数据流。
