Kevin J Connor, Michael E Knappe, David R Oran: Spatial audio processing method and apparatus for context switching between telephony applications. Cisco Technology, Marger Johnson & McCollom, January 4, 2000: US06011851 (81 worldwide citation)

Multiple audio streams are spatially separated with a context switching system to allow a listener to mentally focus on individual point sources of auditory information in the presence of other sound sources. The switching system simultaneously directs incoming sound sources to different spatial pro ...

Kevin J Connor: System for automated testing of perceptual distortion of prompts from voice response systems. Cisco Technology, Marger Johnson & McCollom PC, November 5, 2002: US06477492 (53 worldwide citation)

A Perceptual Speech Distortion Metric (PSDM) generates perceptual distortion values for voice prompts received from a voice response system by comparing the received voice prompts with reference signals associated with the same states in the voice response system. The perceptual distortion values id ...

Bich Nguyen, Ilya Slain, Kevin J Connor, Luke K Surazski, Ramanathan T Jagadeesan: Devices and methods for minimizing start up delay in transmission of streaming media. Cisco Technology, Marger Johnson & McCollom P C, May 13, 2008: US07373413 (40 worldwide citation)

Devices and methods are provided for minimizing the startup delay of streaming media transmitted through networks. A server maintains a portion of the media stream stored in an initial burst transmit buffer. At startup, the stored portion is transmitted at a rate higher than the fixed frame rate, ex ...

Bich Nguyen, Ilya Slain, Kevin J Connor, Luke K Surazski: Server and method for transmitting streaming media to client through a congested network. Cisco Technology, Marger Johnnson & McCollom P C, September 19, 2006: US07111058 (24 worldwide citation)

A server is provided with a transmit buffer, a transcoder, and a redundancy encoder. The server is for transmitting streaming media to a client through a communication network. A control unit senses when the network is temporarily congested, and activates the transcoder and the redundancy encoder. T ...

Kevin J Connor, Michael E Knappe, Ramanathan T Jagadeesan: Method and apparatus for testing echo canceller performance. Cisco Technology, Marger Johnson & McCollom PC, February 14, 2006: US06999560 (6 worldwide citation)

A test system measures performance of telephone network echo cancellers using a primary criterion of estimated user annoyance due to audible returned echo. The invention generates live telephone calls, uses real speech samples as stimulus signals and provides tail-circuit emulation using actual meas ...

Randall PJ Ethier, Rajesh Kumar, Robert J Biskner, Chelliah Sivachelvan, Mohamed S Mostafa, Scott S Firestone, Michael A Ramalho, Kevin J Connor, James C Frauenthal, Michael P Hammer: Method and System for Adaptive Media Quality Monitoring. Cisco Technology, Baker Botts, Bart Showalter, December 13, 2007: US20070286351-A1

A method for adaptive media quality monitoring includes monitoring at least one metric of a call between at least two endpoints and detecting a threshold crossing event via the monitoring of the at least one metric. The method also includes executing a threshold crossing action based on detecting th ...
