20140049595 | Videoconferencing System Having Adjunct Camera for Auto-Framing and Tracking - A videoconference apparatus and method coordinates a stationary view obtained with a stationary camera to an adjustable view obtained with an adjustable camera. The stationary camera can be a web camera, while the adjustable camera can be a pan-tilt-zoom camera. As the stationary camera obtains video, faces of participants are detected, and a boundary in the view is determined to contain the detected faces. Absence and presences of motion associated with the detected face is used to verify whether a face is reliable. To then capture and output video of the participants for the videoconference, the view of the adjustable camera is adjusted to a framed view based on the determined boundary. In the end, active video captured in the framed view with the adjustable camera can be sent to a far-end for the videoconference. | 02-20-2014 |
20140072143 | AUTOMATIC MICROPHONE MUTING OF UNDESIRED NOISES - Methods and systems for cancelation of table noise in a speaker system used for video or audio conferencing are disclosed. Table noise is cancelled in one embodiment by providing a signal or a message whenever a key is depressed on a keyboard or a mouse is clicked. When the key depression signal or message is received, the system evaluates whether speech is occurring. If speech is not occurring, then the microphone in the system is muted. However, if speech is occurring, the microphone is not muted for a period of time to allow the speech to be transmitted to the far end. This allows the conference to be continued in the presence of keyboard sounds if speech is occurring at the same time but also silences the keyboard sounds if speech is not occurring. | 03-13-2014 |
20150030149 | Speech-Selective Audio Mixing for Conference - A conference apparatus reduces or eliminates noise in audio for endpoints in a conference. Endpoints in the conference are designated as a primary talker and as secondary talkers. Audio for the endpoints is processed with speech detectors to characterize the audio as speech or not and to determine energy levels of the audio. As the audio is written to buffers and then read from the buffers, decisions for the gain settings of faders for read audio of the endpoints being combined in the speech selective mix. In addition, the conference apparatus can mitigate the effects of a possible speech collision that may occur during the conference between endpoints. | 01-29-2015 |
20150208033 | Pairing Devices in Conference Using Ultrasonic Beacon amd Subsequent Control Thereof - A videoconferencing system has a videoconferencing unit that use portable devices as peripherals for the system. The portable devices obtain near-end audio and send the audio to the videoconferencing unit via a wireless connection. In turn, the videoconferencing unit sends the near-end audio from the loudest portable device along with near-end video to the far-end. The portable devices can control the videoconferencing unit and can initially establish the videoconference by connecting with the far-end and then transferring operations to the videoconferencing unit. To deal with acoustic coupling between the unit's loudspeaker and the portable device's microphone, the unit uses an echo canceller that is compensated for differences in the clocks used in the ND and D/A converters of the loudspeaker and microphone. | 07-23-2015 |
