Abstract: Video is obtained in a video conference session that includes one or more participants in a video conference room, wherein the video conference room includes a video display and a one video camera, and wherein a participant is remote with respect to the video conference room. During the video conference session, it is determined that video captured by the camera in the video conference room includes a face of a person not physically present in the video conference room and which face is displayed on the video display. Video of each participant in the video conference room is assigned to a respective video layout window except for video of the face of the person not physically present in the video conference room that is displayed on the video display.

Abstract: A video conference endpoint determines a position of a best audio pick-up region for placement of a sound source relative to a microphone having a receive pattern configured to capture sound signals from the best region. The endpoint captures an image of a scene that encompasses the best region and displays the image of the scene. The endpoint generates an image representative of the best region and displays the generated image representative of the best region as an overlay of the scene image.

Abstract: Managing noise during an online conference session includes obtaining audio data from an endpoint participating in an online conference session. The audio data is derived from audio captured at the endpoint that includes musical sounds. The audio data is processed to identify a portion of the audio data in which a decibel level of the musical sounds is stable for a period of time. Non-musical noise present, if any, in the audio data with the musical sounds is identified and the non-musical noise is attenuated from the audio data to generate noise-reduced musical audio data. The noise-reduced musical audio data is transmitted for play out at one or more other endpoints participating in the online conference session.

Abstract: Disclosed is a method that includes receiving an audio video stream, decoding the audio video stream to yield decoded video and decoded audio, transmitting the decoded video on a video cable to a display, transmitting a signal, such as, for example, a signal on an audio channel of the video cable, identifying an impulse response based on a received signal responsive to the transmitting of the signal, identifying a delay amount based on the impulse response and transmitting the decoded audio to a loudspeaker according to the delay amount. The cable can include an HDMI cable with the audio return channel (ARC) capability.

Abstract: A telepresence video conference endpoint device includes spaced-apart microphone arrays each configured to transduce sound into corresponding sound signals. A processor receives the sound signals from the arrays and determines a direction-of-arrival (DOA) of sound at each array based on the set of sound signals from that array, determines if each array is blocked or unblocked based on the DOA determined for that array, selects an array among the arrays based on whether each array is determined to be blocked or unblocked, and perform subsequent sound processing based on one or more of the sound signals from the selected array.
