摘要： A load balancer (24) is receiving and identifying multicast streams associated with a multicast session, and selecting at least one of the multicast streams for delivery to a selected stream processor (18). The selected stream processor (18) is selected from a group of stream processors (18) that are providing the Layer 4-7 processing required for the multicast stream. The load balancer (24) will monitor the processed multicast stream provided by the output of the selected stream processor (18), and send the processed multicast stream toward its destination end point (14). The load balancer (18) detects failure in the selected stream processor (18) by monitoring the output of the selected stream processor (18). In case of failure of the selected stream processor (18), the load balancer (24) will select another stream processor (18) for processing the multicast stream, and redirect the multicast stream from the failed stream processor (18) to the selected stream processor (18), wherein the process continues.

摘要： Subscribers request programs from a network based content server and view the requested programs via their customer equipment. The content server receives various programs and breaks the program content for each program into a sequence of program segments, which are logically linked by program association indicia. The content server also receives advertisements and stores the advertisements as advertising segments, which generally contain at least one complete advertisement, but the invention is not limited thereto. Upon receiving a program request from a subscriber, the content server will identify advertising segments to provide along with the program segments for the requested program, and where to place the advertising segments among the program segments. Next, the content server will generate composite association indicia identifying the sequence of program and advertising segments, and effect delivery of the program and advertising segments to the subscriber in the sequence defined by the composite association indicia.

摘要翻译： 用户从基于网络的内容服务器请求节目并通过他们的客户设备查看所请求的节目。 内容服务器接收各种节目，并将每个节目的节目内容分成一系列节目片段，这些节目片段通过节目关联标记进行逻辑链接。 内容服务器还接收广告并将广告存储为广告片段，广告片段通常包含至少一个完整广告，但是本发明不限于此。 一旦接收到来自订户的节目请求，内容服务器将识别要与所请求的节目的节目片段一起提供的广告片段以及将广告片段放置在节目片段中的何处。 接下来，内容服务器将生成标识节目和广告片段序列的复合关联标记，并且按照由复合关联标记定义的序列实现节目和广告片段向订户的传送。

摘要： A rights management technique allows user terminals to share usage rights that are necessary for accessing associated media content, while ensuring that the media content is not accessed in violation of the usage rights. A content provider may deliver the media content and the associated usage rights to a first user terminal. The usage rights may be sharable as well as divisible. The first user terminal will account for all or that portion of the usage rights that are subsequently transferred, and may retain any remaining usage rights. The first user terminal may transfer all or a portion of any usage rights at the first user terminal to a second user terminal, wherein the transferred usage rights allow the second user terminal to access the media content. The second user terminal may also transfer the usage rights, and perhaps the media content, to other user terminals.

摘要翻译： 权限管理技术允许用户终端共享访问相关联的媒体内容所必需的使用权限，同时确保不违反使用权限访问媒体内容。 内容提供商可以向第一用户终端传送媒体内容和相关联的使用权限。 使用权可能是可共享的，也可以是可分割的。 第一个用户终端将考虑随后转移的所有或部分使用权，并可保留任何剩余的使用权。 第一用户终端可以将第一用户终端的任何使用权限的全部或一部分传送到第二用户终端，其中传送的使用权限允许第二用户终端访问媒体内容。 第二用户终端还可以将使用权利或者媒体内容传送到其他用户终端。
