摘要： Methods and apparatus for supplying unbound applications with data via in-band program channel signaling are described. Unbound applications are STB or other customer premise device applications which continue to run when a tuner in the device changes between program channels. Applications executed in a STB, in accordance with the present invention, e.g., eBIF applications, continue to run despite changes in program channels with data being supplied via in-band signaling, out of band signaling, or a combination of in-band and out of band signaling. The methods and apparatus are well suited for supporting delivery of program catalog information relevant to an individual program channel using in-band signaling reducing or eliminating the need to delivery a multi-channel program catalog via out of band signaling to support various VOD applications.
摘要翻译：描述了通过带内节目信道信令向未绑定应用提供数据的方法和装置。未绑定的应用程序是STB或其他客户端设备应用程序，当设备中的调谐器在程序通道之间变化时，继续运行。根据本发明，例如eBIF应用程序在STB中执行的应用程序继续运行，尽管节目信道的改变，其中数据通过带内信令，带外信令或带内和外部的组合提供的频带信令。所述方法和装置非常适合于支持使用带内信令传送与单个节目信道相关的节目目录信息，从而减少或消除了通过带外信令发送多频道节目目录以支持各种VOD应用的需要。

摘要： 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.
摘要翻译：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。
