    • Methods and apparatus for supporting targeted advertising and/or other targeted applications in set top boxes which use data and/or applications, e.g., EBIF (Enhanced TV Binary Interchange Format) applications, are described. Application level targeting is supported in which an application running on different STBs presents different application behavior and/or presents different visual sub-elements depending on the content of a subscriber profile on the particular individual STB. In the case of addressability at the Application Layer an EBIF application can target different viewers by checking private User Preference Items at runtime. Addressability at the signaling/platform level is also supported allowing targeting of a specific application or a sub-element within an application to a specific target group. In this scenario the particular applications/sub-elements are loaded on the set-tops that belong to a target group, e.g., satisfy targeting constraints specified in private targeting metadata that is received in an MPEG stream.
    • 描述了用于在使用数据和/或应用(例如,EBIF(增强型电视二进制交换格式)应用)的机顶盒中支持目标广告和/或其他目标应用的方法和装置。 支持应用级别定位,其中在不同STB上运行的应用呈现不同的应用行为和/或呈现不同的视觉子元素,这取决于特定个人STB上的用户简档的内容。 在应用层可寻址性的情况下,EBIF应用程序可以通过在运行时检查私有用户首选项来定位不同的查看者。 还支持信令/平台级别的可寻址性,允许将应用程序内的特定应用程序或子元素定位到特定目标组。 在这种情况下,特定应用/子元素被加载到属于目标组的机顶盒上,例如,满足在以MPEG流中接收的专用定向元数据中指定的目标约束。

    • A method, a device, and a system for managing permission information are provided. The method includes: receiving a permission modification instruction, where the permission modification instruction is used to instruct modification of permission information of a file; modifying the permission information according to the permission modification instruction of the file; and sending an Identifier (ID) of the file and the modified permission information to a server. The device includes: a modification module, a processing module, and a first sending module. The system includes: a client and a server. The server and the file jointly store the permission information, thereby effectively improving the flexibility of file encryption, reducing the burden of the server, and improving the performance of the server.
    • 提供了一种用于管理许可信息的方法,设备和系统。 该方法包括:接收许可修改指令,其中使用许可修改指令来指示修改文件的许可信息; 根据文件的权限修改指令修改权限信息; 并向服务器发送文件的标识符(ID)和修改的许可信息。 该装置包括:修改模块,处理模块和第一发送模块。 该系统包括:客户端和服务器。 服务器和文件共同存储权限信息,从而有效提高文件加密的灵活性,减轻服务器的负担,提高服务器的性能。
