Embodiment Construction

[0036] A. Video conferencing endpoint

[0037] Figure 1A A video conferencing device or endpoint 10 in a network 12 communicates with one or more remote endpoints 14. The endpoint 10 has an audio module 20 with an audio codec 22 , and a video module 30 with a video codec 32 , among some common components. These modules 20 / 30 are operatively coupled with the control module 40 and the network module 60 .

[0038] During a video conference, two or more cameras 50A-B capture video and provide the captured video to video module 30 and codec 32 for processing. Additionally, one or more microphones 28 capture audio and provide the audio to audio module 20 and codec 22 for processing. These microphones 28 may be table or ceiling microphones, or may be part of a microphone pod or the like. Endpoints 10 use the audio captured with these microphones 28 primarily for conference audio.

[0039] Independently, microphone arrays 60A-B having orthogonal arrays of microphones 62 also ca...

Abstract

A videoconferencing apparatus automatically tracks speakers in a room and dynamically switches between a controlled, people-view camera and a fixed, room-view camera. When no one is speaking, the apparatus shows the room view to the far-end. When there is a dominant speaker in the room, the apparatus directs the people-view camera at the dominant speaker and switches from the room-view camera to the people-view camera. When there is a new speaker in the room, the apparatus switches to the room-view camera first, directs the people-view camera at the new speaker, and then switches to the people-view camera directed at the new speaker. When there are two near-end speakers engaged in a conversation, the apparatus tracks and zooms-in the people-view camera so that both speakers are in view.

Description

[0001] Cross References to Related Applications [0002] This application is filed jointly with U.S. Patent Applications entitled "Automatic Camera Framing for Videoconferencing" (Attorney Docket No. 199-0717US) and "Voice Tracking Camera with Speaker Identification" (Attorney Docket No. 199-0722US), the entirety of which The contents are incorporated herein by reference. technical field [0003] The present invention relates to video conferencing. More specifically, the present invention relates to video conferencing methods and devices. Background technique [0004] Typically, a camera in a video conference takes a picture of all the participants. Unfortunately, far-end participants lose a lot of valuable content in the video because the size of the near-end participants displayed at the far end will be small. In some cases, far-end participants cannot see the facial expressions of near-end participants, making it difficult to determine who is speaking. These issues gi...
