Abstract: A videoconferencing system has a plurality of displays arranged side-by-side. Top loudspeakers are arranged adjacent the tops of the displays, and bottom loudspeakers are arranged adjacent the bottoms of the displays. A control unit operatively coupled to the displays and the loudspeakers routes video to each of the displays and routes audio corresponding to each display to any of the top and bottom loudspeakers arranged adjacent the display. Thus, the top and bottom loudspeakers form a vertical pair of loudspeakers that output the corresponding audio for its respective display. In this way, the audio for the video of a given display is perceived by participants to originate from the center of the given display. If one of the loudspeakers is not provided, gain setting and mixing between adjacent sets of loudspeakers can produce a virtual loudspeaker for the one that is missing.

Abstract translation: 视频会议系统具有并排布置的多个显示器。 顶部扬声器布置在显示器的顶部附近，并且底部扬声器布置在显示器的底部附近。 可操作地耦合到显示器和扬声器的控制单元将视频路由到每个显示器，并将对应于每个显示器的音频路由到与显示器相邻布置的顶部和底部扬声器中的任一个。 因此，顶部和底部扬声器形成垂直的一对扬声器，其输出相应的音频以用于其相应的显示器。 以这种方式，给定显示器的视频的音频被参与者感知为源自给定显示器的中心。 如果没有提供其中一个扬声器，相邻扬声器组之间的增益设置和混音可以为缺失的扬声器产生虚拟扬声器。
