Abstract:
Video send and receive capabilities of participants are determined by the respective machines determining available combinations, as well as preferences for the receivers. Receiver capabilities are forwarded to the source for computation of negotiated video capabilities through a logic intersection of the determined capabilities based on desired number of streams and resolutions. If a resolution of a send capability exists within the receive capability, the highest frame and/or bit rate may be selected for transmission.
Abstract:
Technologies are described herein for detecting and managing congestion on a shared network link. A determination is made whether the shared network link is congested based on loss rate and round-trip time (RTT) between a computer and a receiver operatively coupled by the shared network link. Upon determining that the shared network link is congested, a back-off operation is performed on the computer. The back-off operation may reduce an allocated bandwidth of the computer on the shared network link by transforming a higher allocated bandwidth into a lower allocated bandwidth.

Abstract:
Video receiving capabilities of participants and source capabilities are compared and conference capabilities for providing different resolutions, frame rates, bit rate, and number of streams are determined by maintaining a conference receiving capability list updated as number and capability of participants' changes. Preferred receiving capabilities of participants are also taken into account in determining conference characteristics based on comparison with allowed capabilities.
Abstract:
A multiple frequency band planar antenna formed on one-side surface of a circuit board comprises: a first antenna pattern, a second antenna pattern, a third antenna pattern and a fourth antenna pattern, each antenna pattern further comprising an elongated portion and a conductor portion; wherein the second elongated portion at a point between its two ends is short-circuited to a feeding transmission line formed on another-side surface of the circuit board through a via. Thus, the multiple frequency band planar antenna can operate at three frequency bands with their central frequencies at 2.4 GHz, 3.5 GHz and 5.8 GHz, respectively, suitable for both WIFi LAN and WiMAX MAN applications.
