Patent number: 7853856Abstract: The invention relates to the generation of error correction data for available data packets and to the reconstruction of missing data packets based on available data packets and available error correction data. In order to enable an efficient error correction, the data packets are distributed at an encoding end to at least one block of data symbols, each data symbol being of equal size. Then all data symbols of a respective block are used in an encoding operation for forming a respective one of at least one error correction symbol for this block. At a decoding end, received data packets are distributed again to a block of data symbols and missing data packets are reconstructed based on these data symbols and on error correction symbols associated to the block.Type: GrantFiled: October 6, 2005Date of Patent: December 14, 2010Inventors: Ramakrishna Vedantham, David Leon, Igor Curcio

Patent number: 7844727Abstract: A method and system for adaptively controlling level of a receiver buffer in a client in a multimedia streaming network. The multimedia streaming network has a server for providing streaming data to the client. The server is responsible for adapting the transmission rate to the reception rate or congestion control, and for adapting the sampling rate to the transmission rate. Thus, the server manages the shift and keeps it within the rate adaptation operating range. The client is responsible for compensating for the packet transfer delay variation, which is also known as network jitter. The client is also responsible for setting parameters of the server rate adaptation operating range. The client chooses and sends the shift parameters to the server, but it is up to the server to adapt its encoding rate or transmission rate when responding to the parameters.Type: GrantFiled: April 16, 2004Date of Patent: November 30, 2010Assignee: Nokia CorporationInventors: David Leon, Viktor Varsa, Igor Danilo Diego Curcio

Patent number: 7786611Abstract: A ducting structure for generating wind power from a vertical structure. The ducting structure includes a main housing sized and shaped to be coupled to a wind turbine and located on the vertical structure. The main housing includes a vertically oriented aperture having a first duct leading to the coupled wind turbine and a horizontally oriented aperture having a second duct leading to the coupled wind turbine. The vertically oriented aperture captures a prevailing wind and the horizontally oriented aperture captures an updraft flowing upwardly along the vertical structure. The captured updraft and the prevailing wind are guided through the first and second ducts past the coupled wind turbine.Type: GrantFiled: June 12, 2009Date of Patent: August 31, 2010Inventors: Thomas Manaugh, David Leon

Patent number: 7631085Abstract: Methods, systems, transmitters, receivers, network elements and software applications in a system for acknowledging the reception of sets of data objects, wherein one or more transmitters transmit one or more sets of data objects within respective point-to-multipoint transmission sessions to a plurality of receivers, and wherein repair requests and/or delivery verification reports are transmitted by at least one of said receivers to network elements within point-to-point transmission sessions. Different back-off times are assigned for delivery verification reports and repair requests, at least two delivery verification reports of one receiver are jointly transmitted within one point-to-point transmission session, and a delivery verification report is transmitted after a completed repair session within the same point-to-point transmission session used by the repair session. Furthermore, a minimum set of parameters to be sent in delivery verification reports is shown.Type: GrantFiled: August 30, 2004Date of Patent: December 8, 2009Assignee: Nokia CorporationInventors: Ramakrishna Vedantham, David Leon, Igor Curcio

Patent number: 7606928Abstract: A method to provide to a sender of RTP packets the actual receiver buffer fullness level in a receiver of the RTP packets at a certain time instant represented as remaining playout duration in time. The receiver sends in an RTCP report the sequence number of a selected RTP packet in the receiver buffer and the time difference between the scheduled playout time of this packet and the current time. Based on this timing information, the sender calculates the amount of time it would take for the receiver buffer to empty if the receiver continues to playout at normal speed and no further RTP packets arrive to the receiver buffer. This receiver buffer fullness level information can be used at the sender to adjust the transmission rate and/or nominal playout rate of the RTP packets in order to maintain a targeted receiver buffer fullness level.Type: GrantFiled: March 21, 2003Date of Patent: October 20, 2009Assignee: Nokia CorporationInventors: Ru-Shang Wang, Viktor Varsa, David Leon, Emre Baris Aksu, Igor Danilo Diego Curcio

Patent number: 7594154Abstract: To support a forward error correction scheme, in which a code of the forward error correction scheme is employed at a transmitting end for encoding data for a transmission to a receiving end, the transmitting end compresses at least one binary parity check matrix associated to the employed code of the forward error correction scheme. The transmitting end then provides the compressed binary parity check matrix for a transmission to the receiving end. The receiving end receives the compressed binary parity check matrix and decompresses it for use in a forward error correction based on encoded data received from the transmitting end.Type: GrantFiled: November 17, 2004Date of Patent: September 22, 2009Inventors: Ramakrishna Vedantham, David Leon, Igor Curcio
