摘要： A method of multicasting digital data to a user accessing an Internet connection is disclosed. The method includes placing digital data that is to be multicast in IP protocol to generate IP digital data. The IP digital data is transmitted from a transmission site to a remote Internet point of presence through a dedicated transmission channel substantially separate from Internet backbone. The dedicated transmission channel may be, for example, a satellite channel. At the remote Internet point of presence, the IP digital data is multicast for delivery to at least one receiving Internet user's apparatus connected to but distal from the remote Internet point of presence.

摘要： A method and apparatus enables legacy NSP and other networks which use ATM switches that lack multicasting capabilities to acquire and distribute IP multicast transmissions to content subscribers on ATM DSL networks. The method and apparatus further provides the ability for insertion of local advertising content into received IP streams for subsequent distribution over an ATM network. An IP ATM Multicaster (IAM) converts IP multicast signals to ATM protocol and replicates the converted IP multicast packets in response to IGMP join requests received from one or more prospective multicast content recipients. The IAM acts as a bridge between IP protocol and ATM protocol environments that handles conversions and encapsulation protocols between environments. An alternate embodiment utilizes an ATM IP Multicast Inserter (AIMI) that embodies similar functions as the IAM but without using multiple virtual circuits. A Local Ad Inserter (LAI) is provided for enabling insertion of advertisements into the IP multicast data stream prior to insertion into the ATM network.

摘要： A method and system is provided for inserting national, regional, and/or demographically targeted information content, such as commercial advertisements, into streaming IP multicast program content delivery streams, such as streaming audio, video or other multimedia content, provided to Internet users via a wide area multicast distribution network. One or more IP datagram/packet replication devices accept packets of streaming digital data content from a multicast content distribution network or other streaming digital content generation source to produce a plurality of multicast content streams. Content streams are provided to an advertisement insertion (AI) device that is capable of implementing per-stream insertion of predetermined advertisement content. Multicast content streams containing the inserted advertisement content are distributed to multicast recipients by one or more regional IP service provider networks. Specific demographic targeting of inserted advertisement content is accomplished on a per-stream basis at the regional network level by modifying IP header and UDP header information per data packet during the packet replication process.
摘要翻译：提供了一种方法和系统，用于将诸如商业广告的国家，区域和/或人口统计信息内容插入到提供给互联网用户的流式IP组播节目内容传送流中，例如流式音频，视频或其他多媒体内容，经由广域网组播分配网络。一个或多个IP数据报/分组复制设备接收来自多播内容分发网络或其他流数字内容生成源的流数字数据内容的分组，以产生多个多播内容流。将内容流提供给能够实现预定广告内容的每流插入的广告插入（AI）设备。包含插入的广告内容的多播内容流由一个或多个区域IP服务提供商网络分发给多播接收者。通过在分组复制过程期间通过修改每个数据分组的IP报头和UDP报头信息，在区域网络级别上基于每个流来实现插入的广告内容的特定人口学目标。
