摘要： A method and apparatus for the automatic access control to multimedia presentations at the receiver in accordance with a viewer selected access mode and access classification data encoded into the multimedia presentation. Screening classification codes (SCCs) are embedded in the Audio Visual Material (AVM) delivered to a subscribers home station. The screening classification codes identify the type of content that follows in the AVM stream. For instance, violent content (video and/or audio) provided to a home station may contain a SCC that indicates violent scenes or violent action is forth coming in the AVM stream. The home station takes the SCC that are encoded and/or embedded in the AVM stream and applies a subscriber selected screening criteria. The screening criteria or suppression criteria are AVM manipulation commands. These AVM manipulation commands can blank the audio and/or video, cause the display of the last acceptable frame, perform obscuration transforms on the AVM stream or otherwise manipulate the audio and/or video portions of the AVM stream. The subscriber associates an AVM manipulation command with each of the available SCCs. The home station applies the subscriber desired manipulation commands to the AVM stream. Information on the subscriber selections are provided to an upstream node for subscriber behavior collection analysis.
摘要翻译： 一种用于在雅舞蹈接收机与编码成多媒体呈现中的观众选择访问模式和访问分类数据自动访问控制多媒体演示方法和装置。 筛选分类代码（SCCS）嵌入在交付给用户本站的视听材料（AVM）。 筛选分类代码标识的内容的类型做了如下的AVM流。 例如，暴力内容（视频和/或音频）提供给本站可能包含SCC确实表明暴力场面或暴力行动是AVM流中即将出台。 本站取SCC做了AVM流中被编码和/或嵌入和应用一个订户选择的筛选标准。 筛选标准或抑制条件是AVM操作命令。 这些AVM操作命令可以空白的音频和/或视频，导致负载框架上可接受的显示，执行遮蔽变换在AVM流或以其他方式操纵AVM流的音频和/或视频部分。 订户相关联，以与AVM每个可用SCC的操纵命令。 本站应用的用户期望操纵命令给AVM流。 在用户选择的信息是在为用户行为分析收集上游节点提供给。
