In an IPTV network, a program content stream is processed to create an artifact detectable by a commercial remover in a program content portion of the program content stream. The artifact may be created by splicing first and second portions of program content together such that the artifact appears in the program content. A commercial remover processing the resultant program content stream erroneously removes portions of program content or leaves portions containing commercial content in the program content stream.

In a network having one or more Audio Video Bridging (AVB) devices, non-AVB bridges are detected by transmitting a maintenance message, such as a unicast linktrace message, from one AVB device such as a residential gateway to another AVB device such as a set-top box or IPTV. AVB devices in the path provide replies indicating whether the port on which the linktrace message was received is connected to a non-AVB bridge. The disclosure has utility in diagnostics problems with IPTV in a network.

A method and an Ethernet local area network are described herein in which the Ethernet local area network is configured to enable a talking device (e.g., microphone) to send a media stream to one or more listening devices (e.g., speakers). In one embodiment, the method for configuring the Ethernet local area network includes the following steps: (1) providing a user of a talking device with a 'relevant' catalog which contains information including positional information about one or more listening devices; (2) allowing the user to interface with the 'relevant' catalog so they can select at least one of the listening device(s); (3) enabling the talking device to send a subscribe-request message to the selected listening device(s) requesting that the selected listening device(s) subscribe to the talking device; (4) and sending a media stream from the talking device to the selected listening device(s).

A method of implementing common interest community services in a presence system comprising creating a common interest community in which an interest state of a presence message is aggregated into a group in the presence system, publishing a member presence information to the common interest community to be selectively made available to a subscribing member of the common interest community and subscribing to the common interest community for receiving the member presence information, wherein a publishing member may selectively grant an access level.

A system, method, and computer readable medium to provide alternative communications during jamming in a presence system, that comprises, registering a mobile device as a presentity to a presence server in the presence system, detecting a communication jamming of the mobile device, providing information related to the detected communication jamming as a state information to the presence server, and upon attempting to communicate with the mobile device while being jammed, providing the state information and offering an alternative communication suggestion.

Dynamic delivery of different commercials to different viewers is achieved using a network node within an IPTV packet-switched network that is coupled to receive both a multicast television program and commercial programs. The network node is able to identify one or more subscribers to the multicast television program and to identify targeted commercial programs for each of the subscribers. The network node further includes a commercial inserter for inserting the respective targeted commercial program for each of the subscribers into the multicast television program to produce respective customized programs and to transmit the customized programs towards the respective subscribers.

A system, method, and computer readable medium for providing secure access between devices comprises generating a new and unique access code by a cell phone, providing the new and unique access code by the cell phone to at least one of: a user of a further device, and the further device, contacting the cell phone by the further device, sending the new and unique access code by the further device to the cell phone, and permitting a connection between the further device and the cell phone, by the cell phone.

A system and method for provisioning presence application services using a customizable presence data model. An ontology depository having at least one domain-specific ontology model for a particular presence application is provided on a communications network. Presence client software associated with a general-purpose presence entity is customized by referencing a domain-specific ontology model of the ontology depository, whereby the presence entity becomes operable to engage in a particular presence application relating to the domain-specific ontology model.

Method and apparatus for implementing a protection scheme for switched networks, and particularly GMPLS networks are described. One embodiment is a method of reserving communications channels comprising an alternative path through a switched network, the network comprising a plurality of nodes interconnected by links, wherein each link comprises at least one communications channel. The method comprises simulating failure of a first link; noting a second link over which traffic on the first link is rerouted in the event of failure of the first link; and transmitting a protection request message ('PRM') from the first link to the second link to request reservation of a specified number of communication channels on the second link.

Protection scheme for a communication network

A network () includes a plurality of packet switches () for routing data packets. The packet switches () include input ports () for receiving packets and output ports () for sending packets. A matrix () passes packets from an input port () to a desired output port (). Input ports () include one or more input queues () and output ports () include an output queue (). Each input queue () is associated with an output queue (). Control messages for passed between the input ports () and output ports () for controlling the acceleration of the rate of data transfer between associated input queues () and output queues ().

In a path-based distributed restoration algorithm provisioned telecommunications network, the origin and destination nodes of a failed path are apprised of the portions of the path that remain intact by &ldquo;reuse&rdquo; messages that are sent from the custodial nodes that are adjacent to the failure. As each reuse message reaches an intermediate node, the node ID of the intermediate node is appended to a field of the message so that, as the reuse messages are propagated along the intact portions of the failed path, a cumulative list of nodes that are encountered by the messages passing from the custodial nodes to the origin and destination nodes is set forth. Thus, the origin/destination node, when in receipt of a reuse message, can read from the field that has the cumulative list of nodes a description of the intact portions remaining from the original path. These intact portions are preferably used only for restoring of the same path that included the portions prior to failure and are not available for restoring any other paths that happened to fail simultaneously.

System and method for restricted reuse of intact portions of failed paths

A system and method for restoring communication between at least one pair of nodes in a network. Distributed intelligence is provided by messaging between adjacent nodes in the network. The messages in combination with user-configurable timers and rules provide fault isolation, forward flooding, reverse linking and connection.
