Abstract: A microphone bar for obtaining audio input for a video conferencing system includes a master module and one or more slave modules. The master module houses a first pair of unidirectional microphones for obtaining audio from opposite sides of the bar, and each of the slave modules houses a second pair of unidirectional microphones for obtaining audio from opposite sides of the bar. Extensions connect the modules together, and at least one bus conducts audio signals through the extension from the microphones to the video conferencing system. The microphones are operable according to a broadside mode of stereo operation when a central axis of the bar is substantially orthogonal to a view angle of the conferencing system. Furthermore, the microphones are operable according to an end-fire mode of stereo operation when the central axis of the bar is substantially parallel to the view angle of the conferencing system.

Abstract: Disclosed herein is a videoconferencing system that has been integrated into a flat panel display or computer monitor. The integration provides an improved form factor for the videoconferencing system. In addition, the integration offers the dual use as a computer monitor and as a videoconferencing system. The system includes a videoconferencing module attaching to a back of the flat panel display. The videoconferencing module has videoconferencing electronics that electronically connect to integral electronics of the display. The system also includes a microphone/camera module attaching to a top of the flat panel display. The microphone/camera module has a camera and microphone that both electronically connect to the videoconferencing electronics.
