摘要： A method and system for manipulating or modifying identifiable objects in a standard broadcast or Internet-based multimedia stream according to a control specification and a content specification. Viewers and/or organizations can independently specify acceptable levels of content on multiple dimensions to satisfy the content specification while minimizing the filtering or blocking to the viewers. A fuzz ball control specification is provided for masking some portion of a video frame. Several fuzz ball specifications can be overlaid to address multidimensional content specifications or rating systems. The manipulation of the multimedia stream can take place at the client (set-top box or computer), intermediate node, the content server or a combination thereof. Proxy servers can modify content specifications for outgoing requests, enabling organizations to specify intranet-wide policies. Multicasting can be supported by using a single stream delivered to multiple clients, each modifying the video using a different specification. The specification to facilitate modification can be done at different granularity levels: the video, a group of frames, or individual frame level and can also be time-based. various protocols can be used to provide the content and/or control specification, including the VBI of a standard broadcast, PICS, RTSP and MPEG protocols.

摘要翻译： 一种用于根据控制规范和内容规范操作或修改标准广播或基于互联网的多媒体流中的可标识对象的方法和系统。 查看器和/或组织可以独立地指定多个维度上可接受的内容级别，以满足内容规范，同时最小化对查看器的过滤或阻止。 提供了一种模糊球控制规范，用于掩蔽视频帧的某些部分。 可以叠加几个毛球规格，以解决多维内容规范或评级系统。 多媒体流的操纵可以在客户端（机顶盒或计算机），中间节点，内容服务器或其组合上进行。 代理服务器可以修改传出请求的内容规范，使组织能够指定Intranet范围的策略。 可以通过使用传递到多个客户端的单个流来支持多播，每个客户端使用不同的规范修改视频。 便于修改的规范可以在不同的粒度级别进行：视频，一组帧或单个帧级别，也可以是基于时间的。 可以使用各种协议来提供包括标准广播，PICS，RTSP和MPEG协议的VBI的内容和/或控制规范。
