20090135810 | Device to terminate a modem relay channel directly to an IP network - A modem data aggregating gateway that supports modem relay functionality for permitting reliable switching of modem traffic between a VoIP network and a data packet switch Internet Protocol (IP) network, s.a. the Internet. The modem relay aggregator may receive modem data encapsulated as Voice over IP (VoIP) data packets in accordance with a Simple Packet Relay Transport (SPRT) mechanism. The packet data may be error corrected and/or decompressed before being repackaged for forwarding to the ultimate destination. In the event that the destination is itself an IP device, the modem relay aggregator may forward the packets directly over the IP network. As a result, if the destination of a modem call is an IP device (such as a Web site or other Internet-enabled device) the technique eliminates two points from a processing path in which digital signal processing (DSPs) would otherwise have to perform modem protocol processing. Otherwise, minimal modem reformatting can be performed at the aggregation point. | 05-28-2009 |
20120127262 | Automatic Layout and Speaker Selection in a Continuous Presence Video Conference - Techniques are provided for managing display layouts for a continuous presence video conference. Each display layout has a fixed number of positions, and one of the display layouts has a maximum number of positions for display to participants in the video conference. The display layouts comprise video display positions for participants in a video conference. When the number of participants is greater than a threshold, one of the positions in that layout is used as a shared position assigned to a video stream of participants not assigned to fixed positions in that layout. The shared position is used in a scanning manner such that video streams of participants not assigned to fixed positions in the layouts are classified as scanning streams and are displayed in the non-fixed (shared) position over a predetermined time interval. | 05-24-2012 |
20130083909 | GAIN CONTROL ENHANCEMENT FOR MODULATED COMMUNICATIONS - In one implementation, a method for implementing gain control enhancement for modulated communications includes establishing a communication session between a first endpoint and a second endpoint. The communication session involves forwarding a call signal using an initial gain level until a state transition is detected in the communication session at a digital signal processor. The detection may occur in a transmitting gateway associated with the first endpoint or a receiving gateway associated with the second endpoint. The state transition indicates modulated communications, which may include fax, modem, or text telephony. For example, communication session may be fax over IP (FoIP). The call signal is forwarded using an adjusted gain level based on the state transition. The adjusted gain level may be selected to avoid clipping in the call signal. | 04-04-2013 |
20130135427 | Techniques For a Rate-Adaptive Video Conference Bridge - A rate adaptive video conference bridge and related techniques are provided. At a video conference bridge, a source video stream is received from a source endpoint device in a network. The source video stream is encoded using a first encoder unit and second encoder unit to generate respective first and second encoded video streams. A determination is made whether to decrease or increase a bit rate of the source video stream based on network condition information. If the bit rate is to be decreased, the first encoder unit is instructed to send the first encoded video stream to a destination endpoint device. If the bit rate is to be increased, the second encoder unit is instructed to send the second encoded video stream to the destination endpoint device. | 05-30-2013 |
20130195262 | Techniques for Handling High Delay Fax Transmissions - A method, apparatus, and logic (encoded within a computer-readable tangible storage media) are provided for detecting, at an intermediate device, a presence of a delay for a fax communication between a source device and a destination device in a network. The delay for the fax communication is sufficient to produce a failure of a corresponding fax operation. The intermediate device includes a buffer to receive packets and is disposed in the network between the source and destination devices. A first time value of the buffer is adjusted at the intermediate device in response to detection of the delay to modify the delay to be within a range enabling the corresponding fax operation to be performed. | 08-01-2013 |

20150015722 | Endpoint Information for Network VQM - Video quality management (VQM) may be provided. First, transmitter metrics corresponding to a video stream may be determined by a transmitting endpoint. The determined transmitter metrics may then be transmitted from the transmitting end point and received by a receiver. The receiver may then determine receiver metrics for a video stream received at the receiver. A quality score may then be determined by the receiver. The quality score may be based on the received transmitter metrics and the determined receiver metrics. | 01-15-2015 |
