20100138501 | END-TO-END VALIDATION IN A PUSH ENVIRONMENT - In a push environment having a communication path along which a service provides messages to a computing device via a gateway, an inactivity timeout value and a registration timeout value enable the computing device to detect failures in the communication path. An application executing on the computing device registers an application endpoint with the gateway. The application separately subscribes to the service to receive the messages. If there is inactivity in accordance with the inactivity timeout value, the application de-registers and re-registers with the gateway, and unsubscribes and re-subscribes with the service. | 06-03-2010 |

20090252315 | Audio Signal Routing - A communication system that includes multiple conferencing devices connected in a daisy-chain configuration is communicably connected to far-end conference participants. Multiple conferencing devices provide improved sound quality to the far-end participants by reducing aural artifacts resulting from reverberation and echo. The daisy-chain communication system also reduces the processing and transmission time of the near-end audio signal by processing and transmitting the audio signal in frequency domain. Each conferencing device in the daisy chain performs signal conditioning on its audio signal before transmitting it in the frequency domain to a mixer. The output signal of the mixer is converted back to the time domain before being transmitted to the far-end. The daisy-chain configuration also provides a distributed bridge to external communication devices that can be connected to each conferencing device. | 10-08-2009 |

20130283143 | System for Annotating Media Content for Automatic Content Understanding - A system for annotating frames in a media stream frames includes a pattern recognition system (PRS) to generate PRS output metadata for a frame; an archive for storing ground truth metadata (GTM); a device to merge the GTM and PRS output metadata and thereby generate proposed annotation data (PAD); and a user interface for use by the HA. The user interface includes an editor and an input device used by the HA to approve GTM for the frame. An optimization system receives the approved GTM and metadata output by the PRS, and adjusts input parameters for the PRS to minimize a distance metric corresponding to a difference between the GTM and PRS output metadata. | 10-24-2013 |
20140168517 | System for Annotating Media Content for Automatic Content Understanding - A method to correct for temporal variability in incoming streams of media and data to optimize the performance of a pattern recognition system includes the steps of receiving from one of the incoming streams a point in time when an event is announced, applying a probability distribution about the point in time, shifting a point of highest probability of the probability distribution back in time by an amount effective to accommodate for a delay between the event and the announcement, comparing a detected pattern of the event to a stored pattern of similar events and applying a confidence value to the comparison, and confirming to the pattern recognition system that the event occurred at the point of highest probability when the confidence score exceeds a predefined threshold. The method is useful to determine the time at which a particular play occurs during a sporting event, such as the time of a shot-on-goal in a soccer match. | 06-19-2014 |
