    摘要: A method, apparatus, and computer instructions for providing identification and monitoring of entities. A distributed data processing system includes one or more distributed publishing entities, which publish computer readable announcements in a standard language. These announcements may contain a description of a monitoring method that may be used to monitor the behavior of one or more distributed monitored entities. These announcements also may include information used to identify a monitoring method that may be used by the distributed monitored entity to monitor its own behavior or by a distributed consumer entity to monitor the behavior of the distributed monitored entity. The monitoring also may be performed by a third-party distributed monitoring entity.

    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.
