    Abstract: In a videoconference images are not always displayed across the entirety of a viewing endpoint's screen. For example, a user may wish to view more than one videoconference participant at a time. Providing images of more than one participant can result in large amounts of bandwidth being required to transmit the data for all the images from the endpoints to the Multi-Conference Unit and maintain the resolution for all the images. Therefore, the present invention provides a method for reducing the data sent by an endpoint in response to flow control messages sent by the MCU in response to a change in the size at which the endpoint's image is being viewed.

  • Publication number: 20070133414
    Abstract: A method, network receiver and TCP network that enables a receiver-side triggering of the fast retransmit mechanism when a TCP packet/segment is lost or received out-of sequencing order. The receiver is enhanced with a Fast Retransmit Support (FRS) utility that monitors when a next received packet is out-of-order and responds by transmitting a duplicate acknowledgment (ACK) response that includes therein the same window value as the previous ACK. By including the previous clock time, even when the current window value has advanced, the fast retransmit algorithm at the transmitter is triggering before the timeout period.

  • Publication number: 20070133416
    Abstract: A transport control method in a transmitter of a wireless communication system, which includes a transport layer having a congestion control function of transmitting data in a segment basis and retransmitting a segment if an RTO timer expires before receipt of an ACK segment is received in response to transmission of the segment and a MAC layer for detecting receipt of an ACK segment through a wireless link and transporting the detected ACK segment to the transport layer, includes temporarily storing received ACK segments in the MAC layer; detecting an average transmission rate of data segments; and transporting the stored ACK segments to the transport layer at the average transmission rate. Accordingly, by controlling an upward transport rate of a received ACK message by referring to an RTO value of a TCP in a MAC layer, unnecessary retransmission can be prevented by a congestion control function.

    Abstract: A data transmission method etc. is provided. At a transmitting side, if a frame contains transmission data, frame data containing the transmission data and a calculated error-detecting code is generated. If the frame contains no transmission data, frame data containing neither transmission data nor an error-detecting code is generated. At a receiving side, one or more final bit positions of the frame data are assumed in the frame, transmission data and an error-detecting code are assumed in the frame, and the error-detecting code of the assumed transmission data is calculated. If there is a position where the assumed error-detecting code matches the error-detecting code calculated based on the assumed transmission data, it is decided that the position is the final bit position. Otherwise, it is decided that the frame contains no transmission data or that the received frame data contains an error.

  • Publication number: 20070133436
    Abstract: An audio management apparatus manages simultaneous streams of packet-switched audio data for a network conference tool. The apparatus uses a receiver thread to receive packets input from different audio connection points, and a sender thread to send modified packets to the audio connection points. The apparatus uses a plurality of member objects, each associated with a different connection point, to modify the packets to create a custom mix of audio data for each connection point. A common mix, consisting of all of the packets input from all of the connection points, is also maintained, and is used by each of the member objects, along with the packets maintained by the member objects, to perform the desired mixing. The overall number of receiver threads and sender threads is independent of the number of member objects, thereby allowing the system to be highly scalable.

  • Publication number: 20070133445
    Abstract: The present invention provides a method and an apparatus for a wireless communication between a base station and at least one mobile station. The method includes receiving a request for a data rate from the mobile station on a reverse link channel to the base station. The method further includes, in response to the request, skipping a first slot after a delay for a portion of a slot on a forward link transmission before transmitting a data packet in a second slot. By beginning the forward link transmission at the start of the second slot, for example, a software module may cause the base station to skip a slot immediately after the half slot delay. This additional delay of one slot or a portion of the slot may expand radius of a cell for a wireless communication between the base station and the mobile station in a relatively high-speed wireless data network.

  • Publication number: 20070133462
    Abstract: A transmitter (22) of a telecommunications system transmits hopped pilot signals as a distinct (i.e., locally unique) time-frequency shift of a time frequency plane array wherein the pilot signals are hopped using a hopping sequence. Differing transmitters of the system (20) preferably transmit using different time-frequency shifts of the same time frequency plane array. The transmitter (22) knows which hopping sequence to employ to generate the time frequency plane array in view of its storage of the hopping sequence, and further knows how to perform its signature time-frequency shift the time frequency plane array thusly created in view of its storage of the time-frequency shift pattern. A receiver (24) identifies a transmitter from which the receiver obtains signals by detecting the particular time-frequency shift of the time frequency plane array and associating the particular time-frequency shift with the originating transmitter.
