摘要： The present invention provides a network based time-shifting architecture where broadcast content is replicated and delivered toward subscribers at different times in different content streams. In operation, a content source delivers unshifted content over a network to a media server, which replicates the unshifted content to provide multiple content blocks. Each content block represents a time-shifted content block of the unshifted content, and as such each time-shifted content block will have essentially the same content. At different times, each time-shifted content block is delivered over a transmission network toward the same or different subscribers. In one embodiment, the time-shifted content blocks are delivered directly or through an encryption function to a multicast server, which controls delivery of the different time-shifted content blocks to television clients of the subscribers.
摘要翻译： 本发明提供了一种基于网络的时移架构，其中广播内容在不同内容流中的不同时间被复制并递送给订户。 在操作中，内容源通过网络将未移动内容传送到媒体服务器，媒体服务器复制未移动内容以提供多个内容块。 每个内容块表示未移动内容的时移内容块，并且因此每个时移内容块将具有基本相同的内容。 在不同的时间，每个时移的内容块通过传输网络向相同或不同的订户递送。 在一个实施例中，将时间偏移的内容块直接地或通过加密功能传送到组播服务器，该组播服务器控制不同时移内容块向用户的电视客户端的传送。

摘要： A wide-coverage, high-capacity, switching network is modeled after a classical space-time-space switch. In the switching network, each of the space stages comprises geographically distributed optical space switches and the time stage comprises a plurality of geographically distributed high-capacity electronic switching nodes. User-access concentrators, each supporting numerous users, access the network through ports of the distributed optical space switches. A user-access concentrator is a simple device which need only have a single access channel to access the network, although two or more access channels may be used. Such a user-access concentrator can communicate with a large number of other user-access concentrators by time-multiplexing the access channel.

摘要： The present invention allows Internet Protocol television (IPTV) services to be provided to different types of subscriber devices over different types of networks via a multimedia subsystem, such as an IP multimedia subsystem. A given subscriber may have one subscription supporting IPTV services to different types of subscriber devices. Each of the subscriber devices may register with a given IPTV application server, which will interact with the various subscriber devices using a common session control protocol, such as the Session Initiation Protocol (SIP). The IPTV sessions may support delivery of various types of streaming content, such as audio or video content, for broadcast or on-demand services. Different IPTV sessions are used to support broadcast and on-demand services. However, within a given broadcast or on-demand IPTV session, channels may be changed or the streaming media may be controlled within the respective IPTV sessions.

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.
