A personalized content overlay is generated and sent for display to a subscriber. The content overlay may be generated in response to a request by the subscriber, such as a request to watch a program. The content overlay can include personalized information tailored to the subscriber based on subscriber information. The content overlay can also include information obtained from a third party, such as an advertiser, that has a preexisting relationship with the subscriber. The content overlay can include one or more triggers that, when activated by the subscriber, enable interactivity between the subscriber and a third party.

A network planning tool and method for configuring a connection-oriented packet network over a WDM optical network without an optical control layer, such as a SONET/SDH layer. The optical network includes a plurality of optical fibers interconnected through nodes and the connection-oriented packet network, such an Ethernet network, MPLS network, or pseudowire network, includes two or more terminal devices. The method and tool function by building an association between the components of the physical layer, such as the optical fiber, and their geographic location or path. The connection-oriented packet network is configured by building multi-link trunks (MLTs) between terminal devices, where the MLTs are built by aggregating lightpaths that traverse distinctive geographic paths. The MLTs are planned and configured through aggregating lightpaths that traverse incongruent sets of photonic elements. A predetermined target for resiliency to physical failure events may determine the degree of congruence allowed between the sets of photonic elements associated with lightpaths in the same MLT.

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.

A method and a protection switching arrangement for protection switching of any one of a plurality of optical signals of a multi-wavelength optical signal from the failure of an optical component is provided. The multi-wavelength optical signal which contains the optical signals is itself rerouted by the use of wavelength agnostic rerouting elements, after which a tunable optical filter is used to obtain from the multi-wavelength optical signal the particular optical signal which would have been affected by the failure. In embodiments of the invention where the failed component is a switching fabric, the multi-wavelength optical signal is rerouted away from the failed switching fabric through a redundant switching fabric after which the particular optical signal is obtained with use of the tunable optical filter.

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.
