20080253299 | Priority trace in data networks - A diagnostic tool for identifying priority errors within a data network is realized using a priority trace data packet. The priority trace data packet is originated at an originating node of interest and terminated at a terminating node of interest. At various intermediate network nodes along the data path between the originating and terminating nodes, the priority trace packet is inspected to determine the current priority value of the priority trace packet. The current priority value is stored in a priority trace field that can be analyzed by a network management node to identify one or more sources of priority errors. | 10-16-2008 |
20090043627 | System and method for calendar presence retrieval - A presence system enables retrieval of calendar presence information of presentities from calendar servers using a calendar agent and calendar interfaces to the calendar servers. Each calendar server maintains calendar schedule information for one or more of the presentites. The calendar agent is operable to generate queries for the calendar schedule information to the calendar servers via a respective calendar interface for each calendar server. The calendar agent is further operable to receive calendar schedule information from the calendar servers via the respective calendar interfaces, and to convert the received calendar schedule information into calendar presence information. Each calendar interface is configured to communicate with the calendar agent via a first protocol and to communicate with a respective one of the calendar servers via a respective second protocol. | 02-12-2009 |
20090080426 | SYSTEM, METHOD, AND COMPUTER-READABLE MEDIUM FOR SYNCHRONIZING MULTICAST CUSTOMIZED CONTENT TO FACILITATE DSLAM COMPLEXITY REDUCTION - A method, computer readable medium, and system for advertisement and content distribution are provided. Supplementary content is synchronized with advertisement slots, or commercial intervals, of a program stream and distributed via separate multicast group addresses. The program content is distributed via an alternative multicast group address during commercial intervals. Ports associated with respective users are mapped or otherwise associated with multiple multicast group addresses in a forwarding table thereby allowing distribution of supplementary content, or alternatively the program content, during commercial intervals. | 03-26-2009 |
20090106792 | METHOD AND APPARATUS FOR ADVERTISEMENT AND CONTENT DISTRIBUTION WITH CUSTOMIZED COMMERCIAL INSERTION DURING CHANNEL CHANGE - A method, system, and computer readable medium of inserting advertisement media content into an Internet Protocol Television (IPTV) system comprises providing media content to a user comprises receiving a first multicast stream containing a first media content at a set top box, displaying the first media content on a display, transmitting a unicast request from the set top box to a remote location in response to a television channel change operation, receiving a second multicast stream containing a second media content at the set top box in response to the unicast request, the second multicast stream including at least one I-frame, and displaying the second media content on the user's display in real-time in response to receiving the at least one I-frame. | 04-23-2009 |
20090135838 | SYSTEM AND METHOD FOR SUPPORTING LINK AGGREGATION AND OTHER LAYER-2 PROTOCOLS PRIMARILY OVER UNIDIRECTIONAL LINKS - Traffic through a bridge or other network device is directed in a manner that enables link aggregation and other layer-2 protocols to operate fully, even though the device may have as few as a single bidirectional link, with the remaining links being unidirectional. The protocol stack logic of the network device includes shim logic that receives traffic and processes it to determine to where it is to be directed. | 05-28-2009 |
20090160943 | Detecting legacy bridges in an audio video bridging network - 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. | 06-25-2009 |
20090210552 | Facilitating access to IPTV content using a portable device while roaming - An IPTV system architecture has an IPTV system and an edge service router connected to the IPTV system. The IPTV system is configured for facilitating delivery of IPTV content dependent upon commands formatted in accordance with a communications protocol supported by the IPTV system. The edge service router is coupled to the IPTV system and includes an IPTV Gateway apparatus. The IPTV Gateway apparatus is configured for receiving commands issued by IPTV subscriber networking devices for affecting IPTV content delivered thereto, for translating the commands from a format in accordance with a communications protocol not supported by the IPTV system to the supported communications protocol, and for providing the translated commands to the IPTV system. | 08-20-2009 |

20140169184 | Ethernet Equipment Utilizing Catalogs And Continuity Checks To Enhance UPnP And AVB Applications - 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). | 06-19-2014 |
