Patent number: 8750325Abstract: Data streams stored in buffers are modulated by modulation sections. Multipliers multiply the signals output from the modulation sections by weights output from a weight control section. The signals output from the multipliers are added up by addition sections, subjected to radio transmission processing by transmission radio sections and sent through antennas. A buffer control section controls the buffers based on a retransmission count output from a retransmission count detection section. The weight control section outputs weights different from weights at the time of previous transmission to the multipliers every time data is retransmitted. This allows a diversity gain at the time of data retransmission to be increased even if a time variation of the propagation path environment for radio signals is slow.Type: GrantFiled: May 24, 2012Date of Patent: June 10, 2014Assignee: Panasonic CorporationInventor: Kenichi Miyoshi

Patent number: 8743913Abstract: A distributed DSLAM, which comprises a head end subsystem located within a switching facility and a remote subsystem located outside of the switching facility. The head end subsystem is operative for routing streams of data from a data network to the remote subsystem over a communication link, while the remote subsystem is operative for transmitting over a set of local loops analog signals comprising digitally modulated versions of the data. Separating the routing and modem functionality between inside and outside plant facilities reduces heat dissipation in the outside plant, leading to increased reliability. Flow control can be performed in the upstream and downstream directions by transmitting portions of individual packets and withholding other portions of individual packets. This is done instead of withholding the transmission of entire packets. As a result, the perceived impact on video quality, for example, is lessened.Type: GrantFiled: March 23, 2011Date of Patent: June 3, 2014Assignee: Telekom Malaysia BerhadInventors: Azrin Bin Aris, Siti Sawiah Binti Ramli, Muhammad Fahmy Bin Khyasudeen, Tet Hin Yeap

Patent number: 7944948Abstract: The present invention sets forth a network-centric service distribution architecture that integrates a wireless access system in the residence, SOHO, business or public environment through the use of a local broadband network, such as a Residential-Business Broadband Network (RBN), to the service provider's broadband transport network and to a service provider's broadband packet network. The system includes Media Terminal Adapter is coupled via the RBN to the access port(s) and via the service provider's broadband transport network to the service provider's broadband packet network. The access port is coupled to the Media Terminal Adapter via either a RBN (e.g., a Local Area Network—LAN) or simply via a traditional POTS line interface. The access port receives and sends wireless signals to a plurality of RBN devices, allowing the user to control theses devices remotely from the residence, business, SOHO or public environments.Type: GrantFiled: August 31, 2005Date of Patent: May 17, 2011Assignee: AT&T Intellectual Property II, L.P.Inventors: Albert T.

Patent number: 7916639Abstract: The present invention relates to a method for data-flow quality control in a Digital Subscriber Line communications system comprising a transmitter, a receiver, and a Digital Subscriber Line intercoupling the transmitter and the receiver. The transmitter sends a data-flow to the receiver, where the data-flow is modulated onto data-carriers according to a bit allocation indicative for the number of bits to be modulated on each data-carrier. The method comprises the steps of the receiver measuring the data-flow quality and subsequently the receiver instructs the transmitter to decrease the bit allocation with a same amount for a plurality of data-carriers in case the data-flow quality is unsatisfactorily low. Then the transmitter decreases the bit allocation accordingly.Type: GrantFiled: August 5, 2005Date of Patent: March 29, 2011Assignee: Alcatel LucentInventors: Etienne André Hubert Van Den Bogaert, Jan Sylvia Verlinden

Patent number: 7916755Abstract: Methods and apparatus for selecting digital coding and/or decoding technology for programming and data delivery over, e.g., a content-based network. In one embodiment, the network comprises an HFC cable or satellite network that includes a server process interfacing with a plurality of customer premises equipment (CPE), and/or associated client devices, each having different capabilities profiles. The server determines the one or more capabilities possessed by the CPE, and evaluates one or more program or content choices for possible delivery to that CPE based on its profile. The server generates a list of programs or content based on this evaluation, and transmits this list to the CPE, which displays the list for viewing by a user. The user is therefore offered a list of available content that is compatible with their specific configuration.Type: GrantFiled: February 27, 2006Date of Patent: March 29, 2011Assignee: Time Warner Cable Inc.Inventors: Charles A Hasek, Jeffrey P.

Patent number: 7907676Abstract: A communication system utilizing an adjustable link has at least a first data transmission circuit including at least a first communication link circuit. The first communication link circuit has a baseband circuit and at least a passband circuit. The baseband circuit corresponds to a baseband sub-channel and the passband circuit corresponds to a passband sub-channel. The first communication link circuit also includes a circuit that distributes a first subset of a data stream having a first symbol rate to the baseband circuit and a second subset of the data stream having a second symbol rate to the passband circuit. The baseband sub-channel and the passband sub-channel are separated by an adjacent guardband of frequencies. The passband carrier frequency is adjusted to define the guardband and the guardband corresponds to a first notch in a channel response of a first communications channel.Type: GrantFiled: October 6, 2009Date of Patent: March 15, 2011Assignee: Rambus Inc.Inventors: Vladimir M.

Patent number: 7864808Abstract: An advanced video multiplexer system designed and optimized for next generation on-demand video distribution is described. The system optimizes identifies a multi-program transport stream best able to accommodate new sessions based upon Quality of Service (QoS) and QAM utilization ratios. MPTS channels are rebalanced via re-grouping and transrating as necessary to optimize bandwidth utilization. Multiple video formats are supported via built-in transcoding. The multiplexer manages encryption resources and supports new sessions using previously allocated encryption resources where possible. Sessions can be grouped into encryption channels either by using a single authorization tier per channel policy, or by requiring all clients of the group to be in physically separated service groups. Encryption channels can be released when a channel no longer serves any clients or when one or more other channels that have been assigned the same entitlement can accommodate any remaining clients.Type: GrantFiled: January 8, 2009Date of Patent: January 4, 2011Assignee: RGB Networks, Inc.Inventors: Edward A.
