Patent number: 8775683Abstract: Method for exchanging control codes between a SIP (Session Initiation Protocol) enabled first network element (1) of an IMS (IP Multimedia Subsystem) network (2), e.g. a mobile terminal connected to such network, and a UPnP (Universal Plug and Play) enabled second network element (3) of a UPnP enabled network (4), both networks being interconnected by an IMS/UPnP interface (5). The first network element (1) addresses a request to a SIP/SIP interface (6), using an address which conforms to the Wildcard PSI (Public Service Identity) format and comprising a PSI address part A which is valid for PSI addressing, and a wildcard address part A?. Then the PSI address part A is converted, in the SIP/SIP interface (6), into a valid SIP URI (Universal Resource Identifier) address B assigned to die IMS/UPnP interface (5), while the wildcard address part A1 is converted into an address parameter B1, pointing or assigned to the second network element of the UPnP enabled network.Type: GrantFiled: November 17, 2008Date of Patent: July 8, 2014Assignee: Nederlandse Organisatie Voor Toegepast-Natuurwetenschappelijk Onderzoek TNOInventors: Hans Maarten Stokking, Fabian Arthur Walraven, Frank Theodoor Henk Den Hartog, Yetao Zhu

Patent number: 8514705Abstract: A method is described for synchronizing the transmission of a stream to a group of end-terminals. The method is used in a system comprising a station transmitting a packetized stream over a network to at least a first and second network node. Each network node comprises a variable delay unit and each network node is connected to one or more end-terminals. In the method the synchronization unit receives arrival time information of a packet in the broadcast stream at the first and second network node. Delay information is calculated for the first and second network node on the basis of the arrival time information of the packet. Further, the delay information is transmitted to the first and second network node so that the variable delay unit in the first and second network node is able to transmit the broadcast stream to the first and second end-terminal in a substantially synchronized way.Type: GrantFiled: October 23, 2008Date of Patent: August 20, 2013Assignees: Koninklijke KPN N.V., Nederlandse Organisatie Voor Toegepast-Natuurwetenschappelijk Onderzoek TNOInventors: Omar Aziz Niamut, Mattijs Oskar Van Deventer, Hans Maarten Stokking, Fabian Arthur Walraven
