PLACEMENT OF TALKER IN 2D OR 3D CONFERENCE SCENE

摘要

PROBLEM TO BE SOLVED: To set up and manage two-dimensional or three-dimensional scenes for audio conferences.;SOLUTION: A conference controller (111, 175) is configured to place an upstream audio signal (123, 173) associated with a conference participant within a 2D or 3D conference scene to be rendered to a listener (211). An X-point conference scene with X different spatial talker locations (212) is set up within the conference scene. The X talker locations (212) are positioned within a cone around a midline (215) in front of the head of the listener (211). A generatrix (216) of the cone and the midline (215) form an angle which is smaller than or equal to a pre-determined maximum cone angle. The upstream audio signal (123, 173) is assigned to one of the talker locations (212) and metadata identifying the assigned talker location (212) are generated, thus enabling a spatialized audio signal.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
